ている。BACKGROUND OF THE INVENTION Many thermoplastic resins have the property of burning when heated, such as by contacting with flame. In order to improve this drawback of thermoplasticity, methods such as filling with inorganic fillers or adding flame retardants are taken, but it is difficult to achieve fundamental flame retardation with the method of blending inorganic fillers. Furthermore, the method of adding a flame retardant often does not provide a sufficient effect, and in some cases, the added flame retardant may impair the properties of the resin. As described above, flame retardant thermoplastic resins have many technical challenges.

That is, all resins such as polyolefins, vinyl resins, polyesters, polyamides, polyethers, polyoxymethylenes, polycarbonates, polyimides, and cellulose derivatives can be used. There are no particular restrictions on the type of raw material for the lignocellulose material to be subjected to flame retardant treatment. That is, wood fibers, hemp, silk thread, fibers made from herbs such as rice, lignocellulose powder, etc. can be used. Among these, particularly suitable for the purposes of the present invention are pulps made from wood. The raw material tree species for pulp are hardwood,
Any softwood may be used, and both bleached pulp and unbleached pulp can be suitably used. The blending ratio of the lignocellulose material to the resin is 5 to 300 parts, particularly preferably 40 to 250 parts, based on 100 parts of the resin.

る。[0006] There are no particular restrictions on the flame retardant treatment applied to lignocellulosic materials. That is, flame retardants such as boron compounds, sodium bicarbonate, water glass, phosphates, ammonium sulfate, polyphosphates, sulfamates, and guanidine salts can be used. Among these, flame retardants containing guanidine salts, especially guanidine sulfamate, as a component are particularly suitable for the purposes of the present invention. There are no particular restrictions on the method of attaching these flame retardants to the nognocellulosic material, but generally, these flame retardants are dissolved in water or other solvents, and the lignocellulosic material is immersed in the solution. Alternatively, this can be achieved by applying or spraying the solution onto the lignocellulose material and then drying it. There is no particular restriction on the adhesion rate of the flame retardant to the lignocellulose material, but 2 to 80% is suitable, and 5 to 50% is particularly suitable.

The temperature when kneading flame retardant-treated lignocellulose material with thermoplastic resin must be at least the melting temperature of the resin, but it must be at a temperature that does not cause decomposition of the flame retardant and kneading aid. It is desirable to do so. When kneading a lignocellulose material subjected to flame retardant treatment with a thermoplastic resin, there is no problem in adding various additives (antioxidants, coupling agents, plasticizers, flame retardants, etc.), fillers, etc.
