うという問題があった。(Prior Art) In recent years, flame-retardant resin compositions that have been used as various sheets, films, or as insulation materials for electric wires and cables are:
In order to prevent smoke during combustion, a non-halogen composition is used to prevent the generation of corrosive hydrogen halide gas. As such a composition, a composition in which a hydrated metal compound such as magnesium hydroxide or aluminum hydroxide is added to a non-halogen resin, ie, a resin such as polyethylene or ethylene-ethyl acrylate, is generally used. However, hydrated metal compounds must be blended in large amounts in order to obtain sufficient flame retardancy, resulting in a problem in that the Is mechanical properties of the resulting composition are significantly reduced. .
そこで、難燃効果の高い赤リンを単独あるいは水和金属

Zinc powder that has been surface-treated with a polymer compound at 0° C. may be used. If the particle size of the zinc powder exceeds 85 μm, dispersion in the resin will be poor, and the IIA mechanical strength of the resulting composition will be reduced. Also, melting point 200-30 used for surface treatment.
Examples of the polymer compound at 0°C include acrylic VA resin and polycarbonate resin. 11 with these resins!

Demonstrates excellent flame retardant effects. The surface treatment method is as follows: 1. Spray your favorite polymer compound at a temperature near the melting point of If the amount is less than this, the flammability will be insufficient, and if it is more than this, the resulting composition will tend to have poor 8! parts.
