Problems solved by technology

[0002] Filling means that in the process of plastic processing and molding, for the convenience of operation, the required various additives, fillers and a small amount of carrier resin are first mixed and kneaded, and the obtained granules and powders are called fillers. Calcium carbonate powder is the main component of the filler in the preparation of plastic products, its addition is very small, about 30%-40%, the cost of the prepared plastic products is high and the strength is not high

Abstract

The invention discloses a plastic filler and a preparation method thereof. The filler comprises, by weight, 35-38% of talcum powder, 35-38% of calcium carbonate powder, 14-20% of plastic particles and 10% of an assistant, a ratio of the talcum powder to the calcium carbonate powder is 1:1, and the assistant is one or a combination of polyethylene wax, stearic acid and a coupling agent. The plastic filler is prepared through primary mixing of all raw materials, secondary mixing, granulation and cooling. The preparation method has the advantages of great convenience in production of plastic product processing enterprises, simplification of the proportioning process, and improvement of the production efficiency and the quality; and the filler prepared mainly from the 1500 mesh talcum powder and the calcium carbonate powder effectively reduces the use amount of plastics in the plastic product manufacturing process, and reduces the manufacturing cost.

Description

technical field [0001] The invention relates to a filling material and a preparation method thereof, in particular to a plastic filling material and a preparation method thereof. Background technique [0002] Filling means that in the process of plastic processing and molding, for the convenience of operation, the required various additives, fillers and a small amount of carrier resin are first mixed and kneaded, and the obtained granules and powders are called fillers. Calcium carbonate powder is the main component of the filler when the plastic product is prepared, its addition is very small, about 30%-40%, and the prepared plastic product has high cost and low strength. In view of the above defects, it is necessary to design a plastic filler and a preparation method thereof. Contents of the invention [0003] The purpose of the present invention is to provide a plastic filler and a preparation method thereof. When the plastic filler is used to prepare plastic products,...
