Abstract

The invention belongs to the field of chemical coatings, in particular to an anti-fog coating. It is composed of the following parts by weight: 30-50 parts of acrylate monomers, 30-45 parts of butyl acetate, 5-8 parts of modified surfactants, 0.5-1.2 parts of initiators, and 0.01-0.05 parts of catalysts , 5-8 parts of active diluent, 15-20 parts of non-ionic surfactant, 0.5-0.8 parts of modified fluorocarbon leveling agent, 35-40 parts of isopropanol, 40-55 parts of deionized water. The anti-fog coating provided by the invention forms a macromolecular hydrophilic acrylic resin, which has sufficient hydrophilicity and can increase the contact angle of water vapor on the surface of the coating film, so that the water vapor will not condense into water droplets and improve the anti-fog effect , also has the advantages of simple preparation process, low equipment investment, low raw material cost, green environmental protection, low VOC, low odor, and maintains the clarity and smoothness of the substrate surface.

Description

technical field [0001] The invention belongs to the field of chemical coatings, in particular to an anti-fog coating. Background technique [0002] Glass and transparent plastic are indispensable materials in people's daily life. When using these materials, the problem of surface fogging often occurs, which brings inconvenience to people's work and life. The so-called atomization, also known as fogging, is more precisely called dew condensation, which refers to the phenomenon that the surface of glass or transparent plastic condenses into tiny dewdrops under high humidity. [0003] Fog on the surface brings many inconveniences to life, and the popularity of cars is getting higher and higher, and people are paying more and more attention to anti-fog. Anti-fog methods are roughly divided into heating methods and surface coating methods. The principle of the heating method is to eliminate the temperature difference between the water vapor and the surface of the object, and ac...
