Problems solved by technology

However, because its surface is hydrophilic, oleophobic and easy to agglomerate, its interface properties are different from those of organic polymers, and its compatibility is poor. Direct or excessive filling will easily lead to a decrease in the mechanical properties of the material.

Abstract

The invention discloses modified calcium carbonate with wide applicable strength. The applicable modified calcium carbonate is characterized by being prepared from the following raw materials in parts by weight: 85-90 parts of calcium carbonate, 3-4 parts of zinc hydroxide, 5-7 parts of butadiene styrene rubber, 2-3 parts of carbon black, 2-4 parts of smectite flour, 2-3 parts of kaolin, 2-4 parts of magnesium silicate, 1-2 parts of antiager RD, 4-6 parts of glycerol triglycerin acid ester, 4-6 parts of polyvinyl acetate, 2-3 parts of dispersible rubber powder and 3-4 parts of modified titanium dioxide. The modified calcium carbonate is reasonable in formula, and simple in production technology, the toughness of a cellulosic fiber is enhanced by reinforcing action on the carbon black, and the modified titanium dioxide is added to coat after the grinding process, so that not only is the dispersibility increased, but also raw materials are saved, and the cost is reduced. The packing disclosed by the invention can be conveniently applied to plastic, rubber, coatings and the like.

Description

technical field [0001] The invention relates to the field of industrial fillers, in particular to a wide-strength modified calcium carbonate and a preparation method thereof. Background technique [0002] Due to its good stability, pure color, low wear, easy processing, non-toxicity, wide range of sources, low price and many other advantages, calcium carbonate is often used to fill plastics, rubber and other materials to increase capacity, increase and reduce production costs. However, because its surface is hydrophilic and oleophobic and is easy to agglomerate, it has different interfacial properties with organic polymers and poor compatibility. Direct or excessive filling will easily lead to a decrease in the mechanical properties of the material. Through modification, its surface properties can be improved, and the comprehensive properties such as dispersibility, compatibility with the polymer interface and mechanical strength of the material can be improved.
