限定され、広範な使用は望めなかった。(Problems to be Solved by the Invention) However, for example, when a composition using ethylene vinyl acetate copolymer (hereinafter abbreviated as EVA) as the polyolein and chlorinated polyethylene as the halogen-containing polymer is used as a coating material for an insulated wire ( (Japanese Unexamined Patent Publication No. 53-43883) It has the disadvantage of generating a large amount of smoke during combustion, and in order to overcome this disadvantage, the addition of smoke preventive agents such as molybdenum compounds is being considered. In addition, when a halogen compound and antimony trioxide, aluminum hydroxide, magnesium carbonate, etc. are blended into polyolefin, a large amount is required, and the obtained This deteriorates the tensile properties, processing properties, etc. of the flame-retardant composition, and the appearance of the molded product tends to be poor, which limits its application and range of use, and its widespread use cannot be expected.

。(Means for Solving the Problems) The present invention consists of a chlorinated polyurethane 30-F0 heavy-weight part with a chlorine content of 25% by weight or more and an ethylene-vinyl acetate copolymer with a vinyl acetate content of 45% by weight or less. 70 to 30 parts by weight of 0 phosphoric acid ester compounds
．． It is characterized by the addition of 5 to 20 weight areas.

ＡのＶＡ含有率を４５重量％以下としたのはＶＡ含有率
が４５重量％を越えると機械特性及び電気特性の低下が
大きいためである。The chlorine content of the chlorinated polyethylene in the present invention is 25
The reason why the content is set at more than 25% by weight is that if the content is less than 25% by weight, the flammability and flexibility of i4 will decrease. Also EV
The reason why the VA content of A is set to 45% by weight or less is that if the VA content exceeds 45% by weight, the mechanical properties and electrical properties will be significantly reduced.
又塩素化ポリエチレンとＥＶＡとの配合比はＥＶＡが７
０重量部を越えた場合には難燃性に劣り、３０重量部未
満の場合には耐熱性に劣るためである。Also, the blending ratio of chlorinated polyethylene and EVA is 7 for EVA.
This is because if it exceeds 0 parts by weight, the flame retardance will be poor, and if it is less than 30 parts by weight, the heat resistance will be poor.

が劣るためである。Further, as a phosphoric acid ester compound that can be used in the present invention, there is tricresyl phosphate, and the addition amount is limited to 0.5 to 20 parts by weight per 100 parts by weight of the base polymer because the addition amount is 0. This is because if it is less than .5 parts by weight, the smoking suppression effect will be small, and if it is more than 20 parts by weight, the heat resistance and thermal stability will be poor.
