Abstract

The invention discloses waterborne environmental-friendly nano coating with super stain resistance, prepared from, by weight, 20-30 parts of silicon resin emulsion, 10-20 parts of mica iron oxide, 6-10 parts of a crosslinking agent, 10-20 parts of a filling material, 3-9 parts of an anti-freezing agent, 2-6 parts of a flame retardant, 5-15 parts of an emulsifier, and 40-60 parts of deionized water. A preparation method includes: weighing materials for use; adding the emulsifier into deionized water, heating, and stirring for dissolution; adding the silicon resin emulsion, mica iron oxide and the filling material in sequence, and dispersing well; adding the crosslinking agent, the anti-freezing agent and the flame retardant, and dispersing well at the speed of 300-900 RPM to obtain the finished product. The waterborne environmental-friendly nano coating with super stain resistance prepared herein has excellent toughness, anti-freezing property, heat insulation and stain resistance, andhas good effect.

Description

technical field [0001] The invention relates to the technical field of nano-coatings, in particular to a super-pollution-resistant water-based environment-friendly nano-coating. Background technique [0002] With the continuous advancement and development of science and technology, there are more and more types of coatings. Nano-coatings are one of many coatings. Due to the small size effect, surface effect, quantum size effect and macroscopic quantum tunneling effect of nanoparticles, they In terms of magnetism, light, electricity, sensitivity, etc., it presents characteristics that conventional materials do not have. Therefore, nanoparticles have broad application prospects in magnetic materials, electronic materials, optical materials, sintering of high-density materials, catalysis, sensing, and ceramic toughening. [0003] At present, the nano-coatings on the market are also diversified, but there is a common defect that the stain resistance is not high. Taking Chinese ...
