The present invention relates to a flame retardant resin composition containing guanidine cyanurate. polyolefin resin, polystyrene resin,
ABS resin, epoxy resin, polyester resin,
Synthetic resins such as acrylic resins, polycarbonate resins, polyamide resins, phenolic resins, polyurethane resins, and polyacetal resins have various properties and are used in various fields. However, since these synthetic resin materials are generally flammable, the scope of their use is limited, with regulations on flame retardancy in some uses, such as electrical appliances, and flame retardancy is strongly desired. ing. Many methods have been proposed to make these synthetic resins flame retardant, but none are perfect yet. For example, in the case of polyolefin resins, the most widely used compounds are halogen-containing compounds,
Bromine compounds are reported to be particularly effective. However, these halogen-containing compounds are unstable to heat and light, and when molding polymers containing flame retardants, they may become colored and turn brown, or if they decompose rapidly, they may corrode the metal surface of the molding machine. I do things. Even if it can be processed, it will discolor if exposed to high temperatures or light. Furthermore, when the amount of flame retardant added increases, flame retardancy increases, but the physical properties of the resin are impaired. Similarly, in the case of vinyl resins, it is necessary to mix an extremely large amount of flame retardant in order to make them sufficiently flame retardant, and as a result, the physical properties of the resin, such as strength, whiteness, However, it has the disadvantage that electrical insulation properties are reduced. As a result of intensive research to obtain a resin composition free of the above-mentioned drawbacks, the present inventors learned that the objective could be achieved by adding a specific compound, and completed the present invention. did. That is, the resin composition according to the present invention is a flame-retardant resin composition containing guanidine cyanurate. Any synthetic resin can be used to add guanidine cyanurate used in the present invention, and some examples include 6・6-, 6-, 6・10-, 11-,
12- Polyamide resins such as nylon, polycarbonate resins, epoxy resins, polyester resins such as polyethylene terephthalate resins, polybutylene terephthalate resins, phenolic resins, polyurethane resins, polyethylene, polypropylene,
Polybutene-1, polypentene-1, ethylene vinyl acetate copolymer, saponified ethylene vinyl acetate copolymer, polyacrylonitrile, polyvinyl chloride, polystyrene, polyvinyl acetate, polyvinyl alcohol, polymethyl methacrylate, ABS
Such as resin. Among these, the combustible synthetic resins used in the present invention are mainly polyester resins such as polyethylene terephthalate, polybutylene terephthalate, 6/6-, 6-, 6/10-, 11-, 12-
- Examples include polyamide resins such as nylon, polycarbonate resins, epoxy resins, phenolic resins, polyurethane resins, and the like. These synthetic resins may be used alone or in combination of two or more. Furthermore, it may contain stabilizers, colorants, weather resistance agents, ultraviolet absorbers, matting agents, antistatic agents, fillers, and other additives. The guanidine cyanurate of the present invention can be produced, for example, by adding a guanidine salt as a solid or an aqueous solution to an aqueous solution of cyanuric acid, adjusting the pH if necessary depending on the type of guanidine salt, stirring the reaction, and filtering out the formed precipitate. It can be obtained by The acid group of the guanidine salt used in this case may be either a weak acid such as carbonic acid or acetic acid or a strong acid such as hydrochloric acid or nitric acid. Further, in the guanidine cyanurate used in the present invention, some of the hydroxyl groups or amino groups may be substituted with other substituents. Guanidine cyanurate is usually present in the resin composition at 1
It is added to contain up to 30% by weight, preferably 2 to 15% by weight. If it is too small, no flame retardant effect can be expected, and if it is too large, it may have no effect on mechanical properties, which is not preferable. In the case of thermoplastic resins, conventional blending methods can be utilized to produce the flame retardant resin compositions of the present invention. That is, it can be produced by mixing synthetic resin powder or pellets with guanidine cyanurate and melting and blending the mixture using a kneader, screw type extruder, Banbury mixer, mixing roll, or the like. In the case of thermosetting resins such as epoxy resins and phenolic resins, they can be manufactured by mixing them with the raw materials used prior to curing. Similarly, it can be present during polymer production reactions by mixing with monomers, etc.
In many cases, it is also possible to mix simultaneously with polymer production. Furthermore, when molding a synthetic resin into a porous body, a method of adding the foaming agent at the same time can also be adopted. The flame-retardant resin composition of the present invention can be molded into any shape such as a film, tape, ribbon, plate, tube, pipe, fiber, foam, etc., and these can be used as construction materials, electrical equipment materials,
It can be used as interior goods, clothing items, and other miscellaneous goods. The flame-retardant resin composition of the present invention has excellent flame retardancy and is particularly superior in that it is less corrosive to metal materials such as molds than flame-retardant resin compositions using halogen-based flame retardants. ing. Furthermore, there is less generation of toxic gases that may have an adverse effect on the human body. Furthermore, since there is no plate-out, there are fewer defective products due to poor mold release or contamination, and there is no damage to the appearance. In addition, unlike metal hydroxide-filled flame-retardant resins, it does not generate moisture, so it can be processed at relatively high temperatures, and large molded products can be easily made. Furthermore, compared to inorganic-filled flame-retardant resins, the specific gravity of the product is as low as that of a general-purpose resin, and the processability is good, making it possible to obtain an economical product. The present invention will be further explained below with reference to Examples. Example 1 5 parts by weight of guanidine cyanurate was added to 100 parts by weight each of polystyrene, polyethylene, polypropylene, polyvinyl chloride, and ABS resin shown in Table 1 under the respective temperature ranges shown in Table 1 using a mixing roll. The mixture was kneaded and press-molded using a heating compressor under 50 atmospheres, and then subjected to an ASTM-D635-56T combustion test. The results are shown in Table 1.

[Table]
Example 2 100 parts by weight of commercially available polyamide 66 chips, 7 parts by weight of guanidine cyanurate, and 0.1 parts by weight of titanium dioxide were melt-kneaded at 270°C using an extruder type kneader, and molded into UL-94 by using an injection molding machine. A flame retardant test piece was prepared as specified in the following. This test piece was tested for flammability in accordance with the regulations of UL-94, and a result of passing 94V-1 was obtained. Note that the product without added flame retardant did not pass 94V-1. The mixed guanidine cyanurate had very good dispersibility, and a molded product with a beautiful surface was obtained. Example 3 Emulsion polymerization solution of vinyl acetate (resin concentration 50% by weight)
6 parts by weight of guanidine cyanurate were added to 100 parts by weight and thoroughly stirred. Next, this emulsified solution was poured onto a glass plate placed on a horizontal surface and left at room temperature for 3 days to remove the aqueous solution and form a film. This film was then thoroughly dried in a vacuum dryer.
At the same time, a film sheet to which no flame retardant was added was prepared in a similar manner. A combustion test similar to that in Example 1 was conducted on these films. As a result, the film without the addition of guanidine cyanurate burned, but the film with the addition of guanidine self-extinguished.
