をあたえる等の問題を生じているものであった。Conventionally, this flame-retardant resin composition has been mainly composed of a halogen-containing resin such as polyhinyl chloride, chloroprene rubber, chlorosulfonated polyethylene, chlorinated polyethylene, or fluorine-based resin, mixed with a halogen-based flame retardant. There is. Therefore, these flame-retardant resin compositions generate halogen gases such as hydrogen chloride when burned, which causes problems such as corroding equipment or being harmful to the human body.

難燃性を向上せしめているものである。From this point of view, resin compositions containing non-halogen-containing resins such as ethylene-vinyl acetate copolymer and inorganic flame retardants such as aluminum hydroxide and magnesium hydroxide have recently been used. When the material burns, it emits crystal water and reduces the combustion heat in the system, improving flame retardancy.

m (maximum specific optical density) was 150 or more, and could not be used practically. It is also possible to mix a large amount of the above-mentioned inorganic flame retardant in order to reduce this smoke-emitting property, but if a large amount of aluminum hydroxide is mixed, the viscosity of the resin composition becomes high and extrusion molding becomes difficult. Become. In addition, when magnesium compounds such as magnesium hydroxide and magnesium carbonate are used in inorganic flame retardant materials, even if a small amount is added, the magnesium ions chemically bond with the crosslinked side of the ethylene acrylic elastomer, which is the base material. This has disadvantages in that it promotes scorch or reduces mechanical properties such as tensile strength and elongation.

とにより難燃性における相乗効果を発揮することが出来
るのである。Further, the resin composition of the present invention contains aluminum hydroxide and acicular calcium metasilicate in combination in order to impart flame retardancy, which is the main objective. The reason for this is that sufficient flame retardancy cannot be imparted by blending these alone, and by using both in combination, a synergistic effect on flame retardancy can be exhibited.

０重量部を超えた場合には引張特性等の機械的特性を低
下せしめるためである。The amount of aluminum hydroxide is 50 to 150 parts by weight, and the amount of acicular calcium metasilicate is 50 to 20 parts by weight.
The reason why it is limited to 0 parts by weight is that if both are less than 50 parts by weight, sufficient flame retardancy cannot be imparted.
Moreover, if the aluminum hydroxide content exceeds 150 parts by weight, the viscosity of the resin composition of the present invention increases, making extrusion molding difficult. Also, 20 acicular calcium metasilicate
This is because if the amount exceeds 0 parts by weight, mechanical properties such as tensile properties will be deteriorated.
