Problems solved by technology

However, the surface of heavy calcium carbonate is hydrophilic and oleophobic, the specific surface area is large, the surface energy is high, and the particles are easily agglomerated. When directly or in large quantities filled in organic matrix materials, it is not only difficult to disperse evenly, but also has a weak binding force with the matrix. , resulting in defects at the two-phase interface and some performance degradation of the composite

Abstract

Disclosed waterproof fireproof modified calcium carbonate is characterized by being prepared from the following raw materials in parts by weight: 90-95 parts of calcium carbonate, 4-6 parts of styrene-maleic anhydride copolymer, 2-3 parts of glass fiber, 3.5-5.5 parts of epoxy resin glue, 2-3 parts of antimony trioxide, 2-3 parts of sepiolite fiber, 0.8-1.2 parts of titanate coupling agent TC-114, 3-5 parts of ethyl silicate, 1-2 parts of trioctyl phosphate, and 2.5-3.5 parts of modified titanium dioxide. According to the modified calcium carbonate, glass fiber, ethyl silicate, trioctyl phosphate and other flame-retardant fireproof raw materials and oily waterproof raw materials are added, and modified titanium dioxide is added, so that the dispersing effect is increased. The modified calcium carbonate is usable as a building filling material. A produced product is smooth and flat in surface and excellent in mechanical properties. The waterproof fireproof modified calcium carbonate has good social popularization value.

Description

technical field [0001] The invention relates to the field of industrial fillers, in particular to a waterproof and fireproof 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, such as plastics, rubber, adhesives, coatings, etc., and occupy an important market share. Compared with metal materials, polymer materials are widely used in many fields due to their advantages of light weight, easy processing, and good specific strength. However, the surface of heavy calcium carbonate is hydrophilic and oleophobic, the specific surface area is large, the surface energy is high, and the particles are easily agglomerated. When directly or in large quantities filled in organic matrix materials...
