Abstract

The invention discloses a calcium carbonate filler for improving the stability of plastic products and a preparation method thereof. The calcium carbonate filler consists of 0.2 parts of sodium bicarbonate, 0.8 parts of stannous chloride, 1.4 parts of sodium polyacrylate and 4 parts of nano iron slag , 0.9 parts of isopropyl palmitate, 0.9 parts of pregelatinized starch, 1.1 parts of magnesium stearate, 0.9 parts of cerium dioxide, 230 parts of heavy calcium carbonate, 8 parts of auxiliary agents, and 30 parts of water; its preparation method Yes: add sodium bicarbonate, stannous chloride, sodium polyacrylate, and cerium oxide into water, and stir to obtain a slurry; blow hot air to heavy calcium carbonate to make it tumbling, and then spray mist into the tumbling powder After fully mixing, keep the temperature at 70-80°C, continue to tumbling for 30-40 minutes, then dry, add to the high-speed kneader, add other remaining ingredients, then raise the temperature to 110-120°C, keep warm and knead for 15- After 20 minutes, grind it into 5-40μm particles.

Description

technical field [0001] The invention relates to the technical field of preparing plastics, in particular to a calcium carbonate filler for improving the stability of plastic products and a preparation method thereof. Background technique [0002] Calcium carbonate has made a significant contribution to the sustained and rapid development of the plastics industry, and has also made significant contributions to saving oil resources, implementing circular economy strategies, changing economic growth models, and building a resource-saving and environment-friendly society. In the new historical period, in the face of more and more calcium carbonate products entering the market, more and more other types of non-metallic mineral powder materials are competing in the plastic application market. Calcium carbonate currently has chemical stability as a plastic filler. The disadvantages of poor performance and weak bending strength lead to defects in the performance of plastic products....
