Abstract

A modified calcium carbonate with enhanced wear resistance is disclosed. The modified calcium carbonate is characterized in that: the modified calcium carbonate is prepared from raw materials 85-90 parts by weight of calcium carbonate, 2-3 parts by weight of quartz powder, 5-7 parts by weight of epoxy resin, 4-6 parts by weight of glycerol triacetate, 6-8 parts by weight of nylon 66, 3-4 parts by weight of molybdenum disulfide, 2-3 parts by weight of copper oxide, 2-3 parts by weight of smashed nut shell, 1-1.5 parts by weight of high-wear-resistance carbon black, 2-3 parts by weight of brown aluminium oxide, 4-6 parts by weight of turpentine, 2-4 parts by weight of liquid paraffin and 3-4 parts by weight of modified titanium dioxide; by addition of the high-wear-resistance carbon black, the molybdenum disulfide and other wear-resistant lubricants, a filling material has a self-lubricating property so as to reduce external friction, thus achieving an effect of wear resistance; and by adoption of the modified titanium dioxide, the dispersion property and the compatibility are enhanced, thus generating strong binding force and not reducing the comprehensive properties of products. The modified calcium carbonate is used as additives for plastics, rubber and coating, and the like.

Description

technical field [0001] The invention relates to the field of industrial fillers, in particular to a modified calcium carbonate with enhanced wear resistance 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. [0003] 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 o...
