Nano weather-resistant coating and preparation method thereof

Abstract

The invention discloses a nano weather-resistant coating and a preparation method thereof. The nano weather-resistant coating comprises the following components in parts by weight: 9-17 parts of polytrifluorochloroethylene resin, 5-12 parts of polyvinylidene fluoride resin, 4-9 parts of tri-chloride-vinyl acetate resin, 3-8 parts of polyethylene glycol 6000, 3-7 parts of aluminum silicate, 3-5 parts of nano zirconium dioxide, 12-22 parts of 2-methyl-1-pentanol, 3-7 parts of diethyl sebacate and 5-10 parts of vinyl distearamide. The preparation method of the nano weather-resistant coating comprises the steps of crushing, mixing and the like. The prepared nano weather-resistant coating has the characteristic of good weather resistance.

Description

technical field

[0001] The invention belongs to the field of coatings, and relates to a coating and a preparation method thereof, in particular to a nanometer weather-resistant coating and a preparation method thereof. Background technique

[0002] After the paint is painted, it forms a uniform and continuous coating film on the surface of the inner and outer walls of the building. The coating film has a certain thickness, flexibility and hardness, and has the characteristics of wear resistance, water resistance, acid and alkali corrosion resistance, pollution resistance, ultraviolet radiation resistance, climate change resistance, mold resistance, etc., which can reduce or eliminate air, moisture, acid rain , Dust, and microorganisms can damage buildings. There are many factors that affect the service life of coatings. Generally speaking, they are: ultraviolet rays, humidity, ozone, high temperature, acid rain, industrial waste gas, etc.
