Description of the Related Art Polypropylene resins are widely used in various fields such as home electric appliances, automobile parts, and containers because of their excellent electrical properties and mechanical strength. Sex is required. In recent years, the demands have become more and more advanced, and the V-
In many cases, those who pass 0 are required. Therefore, various flame retardant methods have been proposed. For example, a method of adding a halogen-based flame retardant such as a chlorine compound or a bromine compound is known, but the use of such a halogen-based flame retardant has a drawback that a corrosive gas or a toxic gas is generated during combustion. .. Therefore, metal hydroxide flame retardants such as magnesium hydroxide and aluminum hydroxide have been proposed as non-halogen flame retardants. However, these metal hydroxide flame retardants have a small effect, and in order to obtain a sufficient flame retardant effect, a large amount must be added,
It has a drawback that it is inferior in moldability and mechanical strength. Therefore, as disclosed in JP-A No. 64-14277, it has been attempted to solve the above problems by using an ammonium polyphosphate flame retardant. That is, [1] (A) thermoplastic resin 100 parts by weight (B) (I) silicone oil 20 to 60% by weight (II) silicone resin 10 to 40% by weight (III) compound containing both phosphorus and nitrogen A gas generating agent selected from the group consisting of or a gas generating agent which is a mixture of a phosphorus-containing compound and a nitrogen-containing compound. Flame retardant additive consisting of 5 to 60% by weight Flame retardant consisting of about 2 to about 30 parts by weight. Composition. [2] The composition according to claim 1, wherein the flammable additive further contains (IV) a polyhydric alcohol in a weight ratio of about 1/9 to about 1/5 with respect to the gas generating agent. The main content is, but the flame retardancy is still insufficient.

If it is less than 0.5 parts by weight, there is no effect in improving the flame retardancy, and if it exceeds 25 parts by weight, moldability is deteriorated, which is not preferable. Next, examples of the ammonium polyphosphate used in the present invention include Sumisafe-P (manufactured by Sumitomo Chemical Co., Ltd.) and PHOS-CHEK.
P-30, PHOS-CHEKP-40 (all manufactured by Monsanto), EXOLIT-422 (manufactured by Hoechst)
Examples of the melamine-modified ammonium polyphosphate include Sumisafe-PM (manufactured by Sumitomo Chemical Co., Ltd.) and EXOLIT-462 (manufactured by Hoechst). These compounds are polypropylene resin 1
It is used in an amount of 18 parts by weight or more, preferably 20 to 50 parts by weight, based on 00 parts by weight. When less than 18 parts by weight is used, high flame retardancy cannot be obtained. Next, as the polyhydric alcohol compound used in the present invention, for example, pentaerythritol, dipentaerythritol, tripentaerythritol, polypentaerythritol, sorbitol, glucose, mannitol, cellulose, glucose, glycerin, trishydroxyethyl isocyanate, polyethylene glycol, Examples thereof include bisphenol A, a reaction product of adipic acid and pentaerythritol, and a reaction product of adipic acid and dipentaerythritol. These compounds are polypropylene resin 100
It is used in an amount of 8 parts by weight or more with respect to parts by weight, preferably 10
30 parts by weight are used. When less than 8 parts by weight is used, high flame retardancy cannot be obtained. Further, the highest flame retardancy is obtained when the weight ratio of ammonium polyphosphate or melamine-modified ammonium polyphosphate and the polyhydric alcohol compound is 3/1 to 1/1. If the polyhydric alcohol compound is less than 1/3, a high degree of flame retardancy cannot be obtained, and if it exceeds 1/1, the flame retardancy may be deteriorated. Further, in the present invention, antioxidants such as phenol compounds usually used for polypropylene resins, neutralizing agents such as calcium stearate and hydrotalcite, lubricants such as amide stearate, light resistance such as phosphite compounds and hindered amine compounds. It goes without saying that a sex improving agent may be used in combination.
