Abstract

The invention relates to a preparing method of glass-flake mastic resin, and belongs to the technical field of preparation of chemical coatings. The preparing method comprises the steps of firstly, taking wheat straw and aluminum chloride as raw materials to prepare a calcined product, then mixing the calcined product with glucose and potato slices for microbial fermentation treatment, conductinghigh-temperature calcination, and then mixing a calcined product with polyurethane, glass flakes and other auxiliary agents to obtain the glass-flake mastic resin. According to the preparing method, part of fibers are decomposed into carboxy groups, hydroxy groups, epoxy groups and other organic groups, the bonding effect among all molecules in the glass-flake mastic resin is enhanced, and the crosslinking density of the microcosmic spatial structure of the mastic resin is increased; meanwhile, cracking of a mastic resin coating is effectively prevented, and shedding is avoided. According to the preparing method, aluminum ions are introduced into the glass-flake mastic resin, then alkaline liquor is dropwise added so that the aluminum ions can form an aluminum hydroxide precipitate to coatthe fibers, and it is ensured that the mastic resin coating is unlikely to be corroded by microorganisms and salt; meanwhile, the glass-flake mastic resin has good permeation resistance and a wide application prospect.

Description

technical field [0001] The invention relates to a method for preparing glass flake cement, which belongs to the technical field of chemical coating preparation. Background technique [0002] Glass flake cement is a mixed material that is composed of resin as a binder and added with glass flake pigments, curing agents, additives and solvents. It can be scraped and wiped. Glass flake cement has become an indispensable and important raw material for the production of heavy-duty anti-corrosion coatings, pearlescent pigments and plastic products due to its excellent properties such as high temperature resistance, corrosion resistance, wear resistance, penetration resistance, adhesion, durability and impact resistance. The glass flake cement component contains a large number of glass flakes, which have strong shielding properties after film formation, can effectively prevent the penetration of corrosive media, and achieve the purpose of isolation and antirust. Glass flake coating...
