Polybismaleimide modified calcium carbonate filler for improving performance of plastic machine

Abstract

Polybismaleimide modified calcium carbonate filler for improving the performance of a plastic machine is prepared from, by weight, 200 parts of calcium carbonate powder, 4-5 parts of ferric stearate, 3-4 parts of molybdenum disulfide, 4-5 parts of polyphenylene, 80-100 parts of hydrogen peroxide, 8-10 parts of peroxidase, 6-8 parts of polyethylene glycol octylphenol ether, 200-250 parts of dimethylformamide, 1-2 parts of 5-hydroxylevulinic acid, 2-3 parts of 4,4-diphenylmethane-bismaleimide, 2-3 parts of diethyl malonate, 0.5-1 part of a catalyst, 1-2 parts of cetyl trimethyl ammonium bromide, 1-2 parts of titanium dioxide, 2-3 parts of methyltin mercaptide, 2-3 parts of sodium lignin sulfonate, 2-3 parts of hydroxyl silicone oil, a proper amount of acetone and a proper amount of deionized water. The filler can improve the hardness, heat resistance and mechanical performance of plastic and is widely applied to the fields of cars, electrical equipment, machines, buildings and the like.

Description

technical field [0001] The invention relates to a calcium carbonate filler, in particular to a bismaleimide-modified calcium carbonate filler for improving the mechanical properties of plastics. Background technique [0002] Calcium carbonate is an important class of functional inorganic fillers. It has the advantages of low price, abundant reserves, stable performance, easy processing, and non-toxicity. It can significantly improve the processing performance and physical properties of materials and reduce production costs. It is widely used In the fields of plastics, rubber, coatings, papermaking, etc., because calcium carbonate is a hydrophilic compound, there are defects such as insufficient compatibility with polymers and poor dispersion in practical applications, and satisfactory filling and reinforcing effects cannot be achieved. Therefore, Calcium carbonate needs to be modified to improve its dispersion and compatibility in various materials, so as to achieve the effe...
