Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curing agent for a radical curable resin and a fixing agent for anchor bolts containing the curing agent.

[0002]

2. Description of the Related Art Conventionally, a curing agent containing an organic peroxide as a main component has been used as a polymerization initiator such as an unsaturated polyester resin, an epoxy acrylate resin or a polyester acrylate resin which is a radical curable resin. These curing agents are used by being classified according to the purpose of use and the temperature of use, and are often used in combination with curing accelerators such as aromatic amines at low temperatures and normal temperatures.

The radical curable resin using an organic peroxide as a curing agent has various uses such as a corrosion resistant lining, a mold molding, and a main agent for a resin capsule anchor. Resins for resin capsule anchors include unsaturated polyester resins,
Epoxy acrylate resins are common.

The resin capsule anchor is used for embedding an anchor bolt in a concrete structure, rock, etc., and installing equipment such as a curable viscous liquid resin and two components of a curing agent or an aggregate. There are two types, one with components, which is used to drive anchor bolts and reinforcing bars with a hammer, and the other which is embedded while being rotated and hit with a hammer drill.

The resin capsule anchor of the type in which anchor bolts and reinforcing bars are embedded while being rotated and hit with a hammer drill, etc., is a main agent that can be hardened in a crushable cylindrical container, a hardening agent that is encapsulated in an aggregate and an inner container. A resin capsule anchor having a double container structure in which an agent is arranged is generally used (Japanese Patent Publication No. 62-37076). Further, in a bolt fixing cartridge comprising an crushable outer container and a crushable inner container, one of which is filled with a viscous liquid resin, and the other of which is filled with a hardening agent of the viscous liquid resin and an aggregate, a solid granular A cartridge for fixing bolts (Japanese Patent Publication No. 4-1160), characterized in that a hardening agent and an aggregate are mixed substantially uniformly, and a viscous liquid resin and a granular aggregate mixed in the viscous liquid resin, An organic binder, a diluent, and a peroxide are molded into a rod shape, and a curing agent having a resin coating layer over the entire surface of the rod-shaped molded article is filled into an opaque cylindrical tube, A fixing agent for fixing bolts is known in which a transparent plastic cap is tightly fitted to the mouth of an opaque cylindrical tube (Japanese Patent Publication No. 63-13000).

There is also known an anchor bolt seal cartridge in which a curable polymer system is multi-segmented by macro-encapsulation, and these macro-capsules are configured as a fixed three-dimensional cylindrical array. 55-32814). They are designed such that when the capsules are crushed, the wall material of the capsules forms flaky debris, and the flakes function as a "static stirrer" to achieve homogeneity of the polymerization system.
Therefore, the capsules are crushed reliably by inserting bolts as a three-dimensional cylindrical array in which the capsules are substantially fixed to each other. Also, the capsule must be such that the wall material can then form flakes.

Furthermore, as a curing composition which is not a fixing agent for anchor bolts but is used for adhesives, sealants, coating materials, molding materials, etc., polymerizable polyacrylates and / or polymethacrylates and organic peroxides can be used. In the composition consisting of the organic peroxide, a redox system is formed, an accelerator for polymerizing the polyacrylate and / or polymethacrylate is used as an internal phase substance, and a film composed of a film-forming hydrocarbon compound is formed. A one-part curing composition in which multiple microcapsules coated with an inner wall film are dispersed is also known (Japanese Patent Publication No. 54-32480).

[0008]

The curing agent for the radical-curable resin is generally liquid, powdery or granular, diluted with an inorganic or organic substance. When these liquid, powdery, and granular curing agents are mixed with a radical-curable resin and poured into a mold or holes, the curing agent is uniformly mixed with the resin in a short time. However, for example, when these curing agents are used as a fixing agent for anchor bolts in a resin capsule anchor having a generally well-known double container structure, the curing agent is filled in a thin inner container, so that the curing agent is Is difficult to fill and the workability is very poor, and the fine particles of the curing agent are scattered during filling into the container to deteriorate the working environment, and the bridge of the curing agent in the filling hopper and container is generated, resulting in poor workability. There is a problem of getting worse. Further, the occurrence of this bridge causes a shortage of the amount of the curing agent added to the capsule, but it is difficult to detect whether or not the curing agent is not added.

The bolt fixing adhesive disclosed in Japanese Examined Patent Publication No. 63-13000 solves the above problems. However, since the molded product of the hardening agent has a rod-like shape, the fixing agent for fixing bolts cannot be mixed and filled with the granular aggregate at the time of capsule production, and the granular aggregate must be filled after the rod-shaped hardening agent is loaded. However, there are disadvantages such as waste of manufacturability, and the granular aggregate to be filled causes a bridge in the gap between the cylindrical tube and the rod-shaped hardening agent, which makes the sedimentation of the granular aggregate worse. In addition, the stick-shaped curing agent often breaks due to rotation and impact of the hammer drill when embedding the anchor bolt, resulting in uneven mixing with the viscous liquid resin, resulting in large variation in the fixing performance and inability to exhibit stable and high fixing performance. Also occurs.

Further, in the technique disclosed in JP-A-55-32814, a phenol resin-glass sphere capable of forming flakes when the usable macrocapsule itself is crushed,
It is limited to hollow clay pillows and gelatin capsules. Therefore, the method of filling the components in the macrocapsule is also limited, and the capsule is immersed in a vacuum in the component,
Alternatively, it is carried out by a method with low productivity such as using a syringe, and the component is limited to a liquid component and cannot be applied to a solid or powder component.

The present invention provides a curing agent for a radical curable resin which has a long product life and is excellent in handleability, exhibits a high fixing performance, is excellent in manufacturability, and is free from problems such as lack of curing agent and unfilling. It is an object of the present invention to provide a high one-component type anchoring composition for anchor bolts.

[0012]

[Means for Solving the Problems] In a hardener molding for a radical curable resin, by forming a granular molding with a curing agent and an ingredient inactive to the radical curable resin, there is no bridge in the container, It has been found that even dispersion is possible, and that by forming a coating layer made of a cured radical curable resin on the surface portion made of a curing agent of a granular molded article, the manufacturability is excellent and the product life is extended. It came to eggplant.

Method of coating the surface of the molded body by a step of immersing it in, and forming a coating layer by the curing reaction at that time, 2) The curing agent molded body is put in a main agent containing a radical curable resin and a curing accelerator, at that time There is a method of forming a resin coating layer on the surface by the curing reaction of, but when used as a fixing agent composition for anchor bolts, considering the simplification of the manufacturing process, cost, etc., the molded product of 2) is added to the main component. A method of forming a resin coating layer on the surface by a curing reaction at that time is more preferable.

As the radical curable resin containing a curing accelerator, epoxy acrylate resin, polyester acrylate resin, acrylic urethane resin, unsaturated polyester resin and the like are used.

The thickness of the coating layer is preferably as thin as possible so long as the active portion of the curing agent can be sufficiently retained, but in order to retain the active portion of the curing agent, the film thickness is 0.
It is preferably set to 3 to 40%.

The coating layer is mainly composed of a radical curable resin, but may contain an unreacted curing agent or molding agent therein.

Regarding the particle size of the granular molded body, considering that the anchoring agent for an anchor is housed in a crushable container, the aggregate and the curing agent are not caught in the container during the mixing and filling with the aggregate, and are Can be settled to 0.5 mm
Those having a particle size of not less than 15.0 mm are preferable because they have good manufacturability and workability. Further, it is more preferable that the particle size is close to that of the aggregate and the curing agent can be dispersed more uniformly in the range of 1 to 10 mm.

The hardness of the granular molded product is not particularly problematic as long as it can be crushed by mechanical stirring at the time of construction as a fixing agent for anchor bolts, but when it is dispersed in the main component as a fixing composition for anchor bolts and further Is a crushing strength of 150 kgf / cm, considering that it is necessary to prevent the granular molded body from collapsing during handling when mixed and filled with aggregate.

The radical-curable resin used in the anchor bolt fixing agent of the present invention is epoxy acrylate resin, polyester acrylate resin, acrylic urethane resin, unsaturated polyester resin, or the like. Further, among the radical curable resins, it is more preferable to use an epoxy acrylate resin or a polyester acrylate resin, which is excellent in fixing performance, low temperature curability and alkali resistance, as a main component.

A reactive monomer may be mixed and used in these radical curable resins. Examples of the reactive monomer include styrene monomer, methyl methacrylate, ethyl methacrylate, ethylene glycol dimethacrylate, cyclohexyl acrylate, n-butyl methacrylate, 2-hydroxyethyl methacrylate, benzyl methacrylate, phenoxyethyl methacrylate, diethylene glycol dimethacrylate, and triethylene glycol dimethacrylate.

These curing accelerators are, for example, 0.2 to 3% by weight with respect to the radical curable resin.

The curing time of the base material of the present invention is determined by the workability and the fixing strength of the adhesive. If the curing time of the main agent is short, the resin will not be embedded due to curing during anchor bolt embedding. Conversely, if the curing time is long, the resin will be uncured during low-temperature construction and the adhesive strength will not be exhibited, or the curing agent When the coating layer is formed by directly adding the granular molded product into the main agent, the reactive monomer permeates the coating layer of the curing agent to react the reactive monomer with the curing agent component. As a result, the curing agent component is lost and the product life is shortened. Therefore, when the curing time of the main agent is adjusted to 60 minutes or less by adjusting the addition amount of the curing accelerator and the minimum curing time measured at 25 ° C. of JIS-K6901 (normal temperature curing property), the resin is not cured at low temperature.

Further, by using an aggregate for the anchor bolt fixing agent of the present invention, the hardening agent molded body is finely crushed, the mixing effect with the main agent is improved, and after hardening, the resin hardened product is also hardened. Is obtained, and higher fixing performance can be exhibited. Aggregate, if the particle size is relatively large, can be crushed by rotation, hitting, etc. during anchor bolt construction, generally magnesia clinker or glass, artificial aggregate such as ceramics, silica stone, Although an inorganic substance such as natural stone such as quartz is used, an organic substance such as a hard plastic such as hard vinyl chloride may be used. As the shape of the aggregate, a granular shape is preferable in consideration of dispersibility, mixing and filling with a curing agent, and the like. The particle size of the aggregate may be determined according to the construction conditions (perforation diameter, anchor bolt size, etc.). The aggregate can be used, for example, in an amount of 0 to 500% by weight, preferably 50 to 300% by weight, based on the main agent.
