Abstract

The invention relates to a calcium carbonate gamma-aminopropyl triethoxy silane modifier, which is characterized by comprising the following components by weight: 1-3 parts of propylene maleate calcium rosinate, 25-30 parts of gamma-aminopropyl triethoxy silane, 5-8 parts of sodium carbonate, 3-5 parts of acrylic acid vinylpyridine copolymer, 5-8 parts of glycol, 5-6 parts of triacetin, 1-2 parts of dioctyltin, and 50-60 parts of water. The modifier has the advantages of scientific and reasonable design, simple process, safety and reliability, easy control, convenient operation, large scale production and low production cost.

Description

technical field [0001] The invention belongs to a production method of calcium carbonate powder. Background technique [0002] At present, calcium carbonate has been widely used in papermaking, plastics, plastic films, chemical fibers, rubber, adhesives, sealants, daily chemicals, cosmetics, building materials, coatings, paints, inks, putty, sealing wax, putty, felt packaging, medicine , food (such as chewing gum, chocolate), and feed, its functions include: increasing product volume, reducing cost, improving processing performance (such as adjusting viscosity, rheological properties, vulcanization properties), improving dimensional stability, reinforcing or semi-reinforcing , Improve printing performance, improve physical properties (such as heat resistance, extinction, abrasion resistance, flame retardancy, whiteness, gloss) and so on. Light calcium carbonate; also known as precipitated calcium carbonate, referred to as light calcium, is calcined limestone and other raw m...
