Abstract

The invention relates to filler capable of enhancing the low-temperature resistance of plastic. The filler is prepared from the following raw materials in parts by weight: 0.5-0.7 part of mineral oil, 2-3 parts of aluminum oxide, 0.4-0.7 part of rosin, 0.5-0.8 part of polyamide wax micropowder, 0.7-1 part of polyester acrylate, 0.1-0.2 part of ammonium persulfate, 1-2 parts of 2-mercaptobenzimidazole, 1-1.5 parts of tetraethylortho silicate, 0.4-0.6 part of ammonia water, 1-2 parts of triphenyl phosphate, 2-3 parts of nanometer iron slag, 200-220 parts of light calcium carbonate, 5-9 parts of an additive and 20-30 parts of water. Since calcium carbonate is uniform in surface modification and good in lipophilicity and has good compatibility with the plastic, the strength and impact resistance of the plastic can be increased; by adding polyamide wax micropowder, the self-lubricating property of the filler is increased, the filler is easily and uniformly dispersed in the plastic and good low temperature resistance is achieved.
