Abstract

The invention provides a noise reduction powdery coating containing glazed hollow beads. The coating is prepared from, by weight, 60-70 parts of epoxy resin, 20-30 parts of polyester resin, 4-6 parts of silicone rubber, 10-15 parts of a curing agent HT835, 1.0-1.3 parts of a polyacrylate leveling agent, 0.5-1.0 part of polypropylene micro-powder wax, 0.2-0.4 parts of benzoin, 10-15 parts of titanium dioxide, 3-4 parts of the glazed hollow beads, 2-4 parts of perlite, 0.3-0.5 parts of linseed oil, 1-2 parts of a silane coupling agent, 0.3-0.6 parts of pure polytetrafluoroethylene micro-powder wax, 8-10 parts of ultrafine calcium carbonate, 5-7 parts of ultrafine blast slag powder, 0.5-0.8 parts of organic bentonite, 0.3-0.5 parts of pentaerythritol tetra[beta-(3,5-tert-butyl-4-hydroxyphenyl) propionate], 0.1-0.3 parts of phosphite ester and 3-5 parts of a modification assistant. The coating has the advantages of low solidification temperature, short solidification time, realization of good levelability, strong adhesion, good appearance and acid and alkali resistance of a film formed by the coating; and the film of the powdery coating has better yellowing resistance than films formed by epoxy powdery coatings in the baking solidification process; and the coating provided by the invention also has the advantages of reduction of spraying energy, production efficiency increase, and noise reduction effect.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a noise-reducing powder coating containing hollow vitrified microspheres and a preparation method thereof. Background technique [0002] With the advancement of modern science and technology and the development of modern industry, the problem of environmental pollution has become increasingly prominent, which poses a great threat to human beings themselves and the environment on which human beings depend. Traditional coatings will produce a large amount of toxic and harmful waste gas and waste water during the manufacturing process or during the construction process, which will pollute the environment, air and water resources, especially solvent-based coatings, which will release Volatile organic compounds (VOC) into the atmosphere, its amount has reached more than 50%, causing serious secondary pollution. This problem has attracted the attention of many industrial countries. [0003] A...
