Antistatic bismale-polyimide modified calcium carbonate filling

Abstract

The invention relates to an antistatic bismale-polyimide modified calcium carbonate filling. The antistatic bismale-polyimide modified calcium carbonate filling is prepared from the following raw materials in parts by weight: 200 parts of calcium carbonate powder, 4-5 parts of glass fibers, 3-5 parts of glycerin monostearate, 1-2 parts of graphene, 80-100 parts of a hydrogen peroxide solution, 8-10 parts of peroxidase, 6-8 parts of polyethylene glycol octylphenol ether, 200-250 parts of dimethyl formamide, 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 methyl tin mercaptide, 2-3 parts of alkyl sodium sulfonate, 2-3 parts of sodium lignosulfonate, 2-3 parts of hydroxyl silicone oil, an appropriate amount of acetone and an appropriate amount of deionized water. The filling disclosed by the invention is homogeneous in particle diameter and good in dispersibility, has good substantivity with organic high polymers, and has favorable stuffing properties.

Description

technical field [0001] The invention relates to a calcium carbonate filler, in particular to an antistatic bismaleimide modified calcium carbonate filler. 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 effect of improving product performance. ...
