example 1

[0025] A processing method of a light flame retardant board, the processing method is: after heating 25 parts by weight of epoxy resin at 50-70°C for 40 minutes, adding 50 parts by weight of polypropylene, 18 parts of flame retardant, 5 parts of foaming agent, 3 parts of stabilizer, and 12 parts of clay are heated while stirring to make them fully mixed, and then the fully mixed components are added to the extruder for extrusion molding. The heating temperature is 130°C, and the heating time is for 3h.

[0026] Wherein, the flame retardant is tris(2-chloroethyl) phosphate acid, and the foaming agent is prepared by mixing calcium carbonate, dichlorotetrafluoroethane, and silicon carbide in a weight fraction ratio of 1:3:5. The stabilizer is formed by mixing 12 parts of pentaerythritol, 5 parts of polyglycerol ester, 22 parts of sodium pyrophosphate, 15 parts of hexamethyltriamine phosphate and 10 parts of ethanol in parts by weight.
