[0032] Example 1
[0033] Preparation of an electrostatic adsorption flame-retardant film:
[0034] (1) Add polyethylene terephthalate and polyvinyl chloride to the smelter, heat it to melt, add homogeneous oil, antioxidant, liquid silica gel and solvent after mixing, and add it after mixing evenly Go to the high-speed dispersing machine to prepare the heat-insulating base layer compound, inject the heat-insulating base layer compound into the injection mold, hold the pressure at 5-10MPa for 5-10 minutes, and then lower to room temperature for demoulding to obtain the heat-insulated base layer .
[0035] (2) The degree of polymerization of ammonium polyphosphate is greater than 1000. Mix the bisphenol A epichlorohydrin resin, ammonium polyphosphate and melamine cyanurate at a high temperature of 90°C, stir and mix uniformly, add the curing agent, and then pour into the mold. Cured at 50°C for 8 hours, then extruded and stretched to form a flame-retardant layer.
