example 1

[0026] An environment-friendly flame-retardant board, which is composed of 92% by weight polypropylene and 8% by weight of flame retardant. The flame retardant is provided by Shenzhen Jiashengwei Chemical Technology Co., Ltd., and the model is MPC-01. :

[0027] 1. Use 92% by weight polypropylene as the base material (homopolymerization or copolymerization grade raw material), add 8% by weight of flame retardant and mix;

[0028] 2. Stir the mixed raw materials at a speed of 100 rpm for 45 minutes;

[0029] 3. Dehumidify and dry the evenly stirred materials for 2 hours at a temperature of 80°C;

[0030] 4. After the material is dried, it is extruded and finally cut into shape by three-roll calendering. The extrusion temperature is 195°C.

[0031] The specific gravity, tensile strength, notched Izod impact strength, elongation at break, flexural strength, heat distortion temperature and other properties of the polypropylene material added with the flame retardant are basicall...
