化学物質に指定されている塩素ガスが発生する。(Problems to be Solved by the Invention) In the conventional case where halogenated epoxy resin is used as a molding material, mechanical properties such as bending strength and tensile strength are 3 to 5 compared to non-halogenated epoxy resin. Therefore, in order to maintain mechanical strength, it is necessary to increase the wall thickness of the molded product. Furthermore, when the resin burns, harmful corrosive gas is generated by the halogen contained in the resin, and in particular, chlorine gas, which is designated as a special chemical substance requiring caution, is generated in the case of chlorinated epoxy resin.

完成するに到った。[Structure of the Invention] (Means for Solving the Problems) Conventionally, as a method for making plastics flame retardant, flame retardant aids such as halogen-based and/or phosphorus-based flame retardants and antimony trioxide are added to plastics. There is a way. As a result of conducting various tests and studies in order to obtain a composition for plastic molding with high reliability, the present inventor discovered that metal hydrates, especially aluminum hydroxide Al2O3.XH2O, were added to plastics, especially epoxy resins. By doing so, we have found that there is no generation of corrosive gases such as chlorine gas that are harmful to the human body, and that it is possible to make the epoxy resin flame retardant. Based on this knowledge, we conducted further tests and research and found that adding inorganic short fibers to hydrated epoxy resin improves bending strength, tensile strength, etc., and improves moldability. The product is strong and has low crack resistance.
That is, they discovered that cracking can be prevented and completed this invention.

強さ、引張強さは約２倍に改善される。また、外観の観
察から、耐クラツク性ら改良されていた。Table 1 As can be seen from Table 1, the composition according to the present invention has the same heat resistance category as the conventional composition, but its bending strength and tensile strength are improved by about twice. Furthermore, from the observation of the external appearance, crack resistance and other properties were improved.
