(Industrial Application Field) The present invention relates to thermoplastic resin and metal, thermoplastic resin and glass fiber reinforced resin (FRP resin), and FRP resin.
The present invention relates to an adhesive composition suitable for bonding resins together. (Conventional technology) Conventionally, thermoplastic resin and metal, thermoplastic resin and
As an adhesive composition used for adhering FRP resins and FRP resins to each other, there is an adhesive composition mainly containing an unsaturated polyester resin. (Problems to be Solved by the Invention) However, unsaturated polyester resins have drawbacks in impact resistance, poor adhesion with other corrugated materials, and furthermore, unsaturated polyester resins do not react well in the presence of moisture. It has disadvantages such as slow speed and difficulty in workability. Therefore, for example, when this adhesive composition is used to bond the main tube and the thin tube (antenna) of the support of a seaweed cultivation net that is constantly exposed to repeated stress in the ocean, the adhesive surface may peel off due to the repeated stress. This resulted in the antenna falling out of the main pipe and the aquaculture net being removed from the tip of the support, resulting in poor durability and impractical use. (Means for Solving the Problems) The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a method suitable for bonding members that are subjected to repeated stresses in the ocean or on land. The purpose of the present invention is to provide an adhesive composition that can be used for
An adhesive composition was prepared by adding and mixing 0.3 parts by weight and 60 parts by weight of talc, and then adding and mixing 60 to 100 parts by weight of urethane resin and 3 to 6 parts by weight of methyl ethyl ketone peroxide. (Function) As mentioned above, in the adhesive composition of the present invention, the amount of cobalt naphthenate as a curing accelerator is increased by 0.3 parts by weight to 100 parts by weight of the thermosetting resin whose main component is unsaturated polyester resin. and 60 parts by weight of talc as a viscosity (adhesion) improver and then mixed, and then the disadvantages of unsaturated polyester resins such as impact resistance, adhesion with other materials, and reaction in the presence of moisture are mixed. By adding and mixing 60 to 100 parts by weight of urethane resin to improve the delay in adhesive properties and 3 to 6 parts by weight of methyl ethyl ketone peroxide as a catalyst and crosslinking agent, an adhesive composition with high adhesive strength can be produced. It is used to bond marine-related components such as net supports for seaweed cultivation, fish cage frames, pearl rafts, etc., and to maintain adhesive strength over a long period of time, and can be repeatedly stressed by wind and waves. It is now possible to prevent the adhesive from peeling off or coming off the adhesive surface. Furthermore, since the urethane resin is added to the unsaturated polyester resin, which is the main component, the reaction rate (curing rate) is increased and the bonding work can be carried out smoothly. (Example) Examples of the present invention will be described below, but the present invention can be implemented in various embodiments and is not limited to these examples. In the examples, parts and % mean parts by weight and % by weight, respectively. Example 1 100 parts of unsaturated polyester resin, 0.3 parts of cobalt naphthenate, 30 parts of saturated polyester resin
1 part, 60 parts of talc were added thereto and mixed well, and then 80 parts of urethane resin and 3 parts of methyl ethyl ketone peroxide (hereinafter referred to as "MEKPO") were added and mixed to produce an adhesive. Note that the saturated polyester resin was added to increase chemical affinity and improve viscosity (adhesive force). Example 2 0.3 parts of cobalt naphthenate and 50 parts of saturated polyester resin per 100 parts of unsaturated polyester resin
1 part, 60 parts of talc were added thereto and mixed well, and then 60 parts of urethane resin and 3 parts of MEKPO were added and mixed to produce an adhesive. Example 3 0.3 parts of cobalt naphthenate and 60 parts of talc were added to 100 parts of unsaturated polyester resin, mixed well, and then mixed with 100 parts of urethane resin.
Three parts of MEKPO were added and mixed to produce an adhesive. Example 4 0.3 parts of cobalt naphthenate and 60 parts of talc were added to 100 parts of unsaturated polyester resin, mixed well, and then mixed with 60 parts of urethane resin.
6 parts of MEKPO was added and mixed to produce an adhesive. Use these adhesives to attach vinyl chloride boards to
After bonding the vinyl chloride board, vinyl chloride board-steel board, and vinyl chloride board-FRP board, and leaving it in an atmosphere at 20℃ for 4 days, JISK6858 and JISK6858 and
Adhesive strength was actually measured using JISK6850. The results are shown in Table 1. Note that the conventional adhesive in the table is an adhesive composition consisting of 100% unsaturated polyester resin.

Adhesives made of urethane resin and unsaturated polyester resin work very well for adhesion between boards and FRP boards, and by mixing urethane resin, interfacial peeling can be prevented and adhesive strength can be increased. I was able to increase it significantly. As explained above, in the adhesive composition of this example, 0.3 parts by weight of cobalt naphthenate and talc are added to 100 parts by weight of a thermosetting resin mainly composed of an unsaturated polyester resin. Add 60 parts by weight and mix, then add urethane resin 60 to improve the shortcomings of unsaturated polyester resins, such as impact resistance, adhesion with other materials, and delayed reactivity in the presence of moisture. ~100 parts by weight and methyl ethyl ketone peroxide 3 as a catalyst and crosslinking agent
By adding and mixing ~6 parts by weight, it is possible to produce an adhesive composition with high adhesive strength, and it is suitable for use in marine-related materials such as supports for seaweed cultivation, fish cage frames, pearl rafts, etc., and for each component. It has become possible to use it for adhesion to maintain adhesive strength over a long period of time, and to prevent it from peeling or coming off from the adhesive surface even when subjected to repeated stress from wind and waves. In addition, with the addition of saturated polyester resin, the elongation of the adhesive is improved, and when used to bond the antenna and the main pipe of a support for seaweed cultivation, the adhesive is sufficiently applied to the mating part. , we were able to increase the adhesive strength between the main pipe and the antenna. (Effects of the Invention) As explained above, in the adhesive composition of the present invention, as described above, a curing accelerator is added to 100 parts by weight of a thermosetting resin containing an unsaturated polyester resin as a main component. 0.3 parts by weight of cobalt naphthenate and 60 parts by weight of talc are added and mixed, and then the disadvantages of unsaturated polyester resins are impact resistance, adhesion with other materials, and delayed reactivity in the presence of moisture. By adding and mixing 60 to 100 parts by weight of urethane resin and 3 to 6 parts by weight of methyl ethyl ketone peroxide as a catalyst and crosslinking agent, it is possible to produce an adhesive composition with high adhesive strength. It is used to bond related components such as supports for seaweed cultivation, fish cage frames, pearl rafts, etc., and each component to maintain adhesive strength over a long period of time, and even when subjected to repeated stress from wind and waves, the bonded surface remains intact. It is now possible to prevent it from peeling off or coming off. Furthermore, since the urethane resin was added to the unsaturated polyester resin, which is the main component, the reaction rate (curing rate) was increased and the adhesion work could be carried out smoothly.
