Abstract

A magnesium hydroxide coated polyimide bismaleimide modified calcium carbonate filler is prepared from the following raw materials by weight: 200 parts of calcium carbonate powder, 4-5 parts of PVC resin powder, 1-2 parts of glass powder, 80-100 parts of hydrogen peroxide, 8-10 parts of peroxidase, 6-8 parts of polyethylene glycol phenyl ether, 200-250 parts of dimethylformamide, 1-2 parts of 5-hydroxylevulinic acid, 2-3 parts of 4,4-dibenzyl methane bismaleimide, 2-3 parts of diethyl malonate, 0.5-1 part of a catalyst, 1-2 parts of cetyl trimethyl ammonium bromide, 40-60 parts of magnesium sulfate, 20-25 parts of calcium hydroxide, 2-3 parts of dimethyl diisooctylmercaptoacetate tin, 2-3 parts of sodium ligninsulfonate, 2-3 parts of hydroxy silicone oil, and a proper amount of acetone and deionized water. The filler has good filling performance, excellent flame retardancy and smoke suppression performance of magnesium hydroxide.

Description

technical field [0001] The invention relates to a calcium carbonate filler, in particular to a magnesium hydroxide-coated 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 p...
