Abstract

The invention relates to a bismalepolyimide-modified calcium carbonate filler having good self-lubricating property. The filler is prepared from the following raw materials in parts by weight: 200 parts of calcium carbonate powder, 4-5 parts of polybutylene terephthalate, 2-3 parts of a silane coupling agent, 4-5 parts of glassiness, 3-5 parts of decabrominated dipheny ethane, 4-5 parts of antimonous oxide, 2-3 parts of melamine cyanurate, 3-5 parts of diphenyl phosphate, 80-100 parts of hydrogen peroxide, 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-diphenyl methane bismaleimide, 2-3 parts of diethyl malonate, 0.5-1 part of a catalyst, right amount of acetone and right amount of deionized water. After being modified, the calcium carbonate is good in self-lubricating property and has good dispersity in polyvinyl chloride (PVC), the lipophilicity is improved, and the mechanical property of the PVC is improved; furthermore, after the filler is used, the cost is lowered.

Description

technical field [0001] The invention relates to a calcium carbonate filler, in particular to a calcium carbonate filler modified by bismaleic polyimide with good self-lubricating properties. 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, paint, paper, etc., because calcium carbonate is a hydrophilic compound, there are defects such as insufficient compatibility with polymers, poor dispersion, and poor self-lubricating properties in practical applications, and satisfactory filling and filling cannot be achieved. Therefore, it is necessary to modify calcium carbonate to improve its dispersion, compatibility and self-lubrication in various mat...
