Abstract
The invention discloses an amino resin-containing calcium carbonate powder modifier. The amino resin-containing calcium carbonate powder modifier comprises, by weight, 3-5 parts of amino resin, 25-30 parts of glycidyloxypropyltrimethoxysilane, 5-8 parts of sodium carbonate, 3-5 parts of an 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 amino resin-containing calcium carbonate powder modifier has the advantages of scientific and reasonable design, simple processes, safety, reliability, control easiness, operation convenience, large-scale production feasibility 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...
