Abstract

The invention discloses multi-purpose ultrafine modified calcium carbonate which is characterized by being prepared from the following raw materials in parts by weight: 85-90 parts of light calcium carbonate, 6-8 parts of ethylene-propylene-diene-terpolymer rubber, 2-3 parts of zinc stearate, 1-2 parts of ferrocene, 2-3 parts of glycerin monostearate, 1-1.5 parts of cetanol, 1-2 parts of tween 80, 2-4 parts of epoxy caster oil, 2-3 parts of quartz powder, 6-8 parts of acetal homopolymer, 1-2 parts of lignosulfonate and 3-4 parts of modified titanium dioxide. By adopting a special production process, such surfactants as glycerin monostearate and oily substances are added in the grinding process and are ground and dispersed uniformly. Modified titanium dioxide is added after being ground, so that the waste of raw materials is avoided and the cost is lowered. The ultrafine packing disclosed by the invention is suitable for production of functional products such as a functional paper auxiliary, a preservative film auxiliary, a pigment or coating additive and the like.

Description

technical field [0001] The invention relates to the field of industrial fillers, in particular to multipurpose ultrafine modified calcium carbonate and a preparation method thereof. Background technique [0002] Calcium carbonate is a very important functional inorganic filler, which is widely used in industrial fields such as plastics, rubber, coatings and papermaking. In the application field of calcium carbonate, most products belong to the category of polymers, [0003] Such as plastics, rubber, adhesives, coatings, etc., and occupy an important market share. Modifiers play an important role in the performance and application of nano calcium carbonate. For example, the addition of dispersant can reduce the agglomeration of nanoparticles and improve the dispersion; the addition of surface modifier can improve the compatibility of nano-calcium carbonate in the polymer system. It can be seen that dispersants and surface modifiers are crucial for the application of nano-c...
