Embodiment 1
[0056]Weigh 16g fumed white carbon black, 0.2g sodium dodecylbenzene sulfonate, 1g maleic anhydride, mix them in a high-speed mixer (temperature 115℃, time 5min, 800r / min), then add 160g low linearity Density polyethylene particles (Yuyao Changying Plastic Chemical Co., Ltd., model LLDPE-5110), after being uniformly mixed, pelletized by single screw extrusion (temperature 120~180℃) to obtain 174g of reinforced carbon chain polymerization Masterbatch.
[0057]Weigh 40g aluminum hypophosphite, 20g sorbitol, 40g melamine in proportion, dissolve them with 1300ml 92% alcohol aqueous solution, stir magnetically for 5min, add 2g sodium lauryl sulfate, 0.5g sodium persulfate, and heat to Keep the temperature at 45°C and stir for 2h. After the mixture is uniform, cool at room temperature. 1g of vinyl triethoxy silane was dropped into the mixed solution, the temperature was raised to 65°C, kept for 3h and stirred, the mixture was cooled to room temperature, and suction filtered, the solid obtain...
