Filler capable of enhancing low-temperature resistance of plastic and preparation method thereof

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.

Description

technical field [0001] The invention belongs to the field of plastics, in particular to a filler for enhancing the low-temperature resistance of plastics and a preparation method thereof. Background technique [0002] Plastics are widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances. In recent years, my country's economy has achieved sustained and stable growth. Industries such as home appliances, automobiles, mobile phones, PCs, and medical equipment have benefited from a favorable external environment and have also achieved rapid development. The development of downstream industries has further stimulated the demand for plastics. Compared with the advanced level, there is still a certain gap in my country's synthetic resin industry. The quantity of some domestic high-end products cannot meet the market demand, and the quality needs to be improved and improved. At present, the performance ...

Problems solved by technology

In recent years, my country's economy has achieved sustained and stable growth. Industries such as home appliances, automobiles, mobile phones, PCs, and medical equipment have benefited from a favorable external environment and have also achieved rapid development. The development of downstream industries has further stimulated the demand for plastics. Compared with the advanced level, there is still a certain gap in my country's synthetic resin industry. The quantity of some domestic high-end products cannot meet the market demand, and the quality needs to be improved and improved.

At present, the performance defects of plastics are manifested in wear resistance, aging resistance, oil resistance, high temperature resistance, strength, chemical stability, bending strength, creep performance, etc., which need continuous improvement
