In particular, if it exceeds 150 parts by weight, the bulk density increases, which is not preferable. Therefore, the amount of diatomaceous earth is 50 to 150 parts by weight, preferably 70 to 120 parts by weight.

果で著しく良好な補強効果が得られる。If the wollastonite as the reinforcing fiber is less than 1 part by weight, a sufficient reinforcing effect cannot be obtained, and if it exceeds 30 parts by weight, the strength is lowered and the bulk density is increased. If the carbon fiber content is less than 1 part by weight, a sufficient reinforcing effect cannot be obtained, and if it exceeds 3 parts by weight, the cost is high. If the pulp content is less than 0.01 parts by weight, sufficient processability cannot be obtained, and if it exceeds 2 parts by weight, the flammability becomes strong. Therefore, as the reinforcing fiber, 1 to 30 parts by weight of wollastonite, particularly 5 to 15 parts by weight, 1 to 3 parts by weight of carbon fiber, particularly 1.5 to 2.5 parts by weight, pulp 0.
It is preferably from 1 to 2 parts by weight, particularly from 0.5 to 1.0 part by weight. In the present invention, the reinforcing fiber is not limited to the mixed use of these wollastonite, carbon fiber and pulp, and other fibers can be used, but by adopting a combination of these. The synergistic effect provides a remarkably good reinforcing effect.

If the amount of the resin solid content is less than 1 part by weight, sufficient strength and processability cannot be obtained, and if it exceeds 20 parts by weight, the flammability tends to be high. It is preferably about 6 parts by weight.
