Abstract

The invention discloses activated calcium carbonate and a preparation method thereof, and relates to the field of activated calcium carbonate, wherein the activated calcium carbonate is prepared from:at least one of calcium carbonate, graphene, ethylene propylene diene monomer, triethyl citrate, liquid epoxy resin, phenyl glycidyl ether, styrene oxide and butyl glycidyl ether: at least one of dicyandiamide, pentylamine trifluoride and 2-ethyl-4-methylimidazole; a coupling agent and an activating agent. The problem that existing activated calcium carbonate is poor in reinforcing, high-temperature-resistant and low-temperature-resistant effects can be solved.

Description

technical field [0001] The invention relates to the field of preparation of active calcium oxide, in particular to an active calcium carbonate and a preparation method thereof. Background technique [0002] As a high-grade filler with high filling content, active calcium carbonate is widely used in rubber, plastic, plastic-steel doors and windows, PVC cable materials, advanced coatings, pipes, tires, shoe soles, polyethylene blown film, sealing strips, glass steel products, cable packaging cloth , papermaking, building materials, ink, daily chemicals, textiles, feed, food additives and other industries. [0003] The existing active calcium carbonate has poor effects in terms of reinforcement, high temperature resistance and low temperature resistance, and needs to be enhanced. Contents of the invention [0004] The purpose of the present invention is to provide a kind of active calcium carbonate and preparation method thereof for above deficiency, solve the problem that t...
