Abstract

The invention specifically relates to an antifogging paint, belonging to the field of chemical paints. The antifogging paint comprises the following substances by weight: 30 to 50 parts of acrylate monomer, 30 to 45 parts of n-butyl acetate, 5 to 8 parts of a modified surfactant, 0.5 to 1.2 parts of an initiator, 0.01 to 0.05 part of a catalyst, 5 to 8 parts of an active diluent, 15 to 20 parts of a nonionic surfactant, 0.5 to 0.8 part of a modified fluorocarbon leveling agent, 35 to 40 parts of isopropanol and 40 to 55 parts of deionized water. The antifogging paint provided by the invention forms macromolecular hydrophilic acrylic resin with sufficient hydrophilicity, so the contact angle of water vapor on the surface of a film formed by the paint can be increased; thus, water vapor does not condense into water drops, and antifogging effect is improved. The antifogging paint has the advantages of simple preparation, low equipment investment, low cost for raw materials, environmental protection, low VOC content and little odor and maintains the definition and cleanness of a matrix 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...
