[0036] The preparation method of the modified silicon-containing powder is a method well known in the art, and is not specifically limited. In one embodiment, the preparation method of the modified silicon-containing powder includes: adding the silicon-containing powder into water, After ultrasonication, heating to 60-80° C., adding a titanate coupling agent, reacting for 3-5 hours, washing and drying to obtain the modified silicon-containing powder.
[0037] The functional masterbatch can be prepared by a method of melt blending, without specific limitation. In one embodiment, the preparation method of the functional masterbatch includes: blending and extruding the preparation raw materials of the functional masterbatch to obtain The functional masterbatch.
[0038] In the present invention, by selecting a low-smoke, halogen-free flame retardant and a flame retardant synergist to work together, the polymer can be promoted to be carbonized, and the free radicals can be removed...
