Polyurethane cured acrylic resin anti-fogging and abrasion-resistant paint and preparation method thereof

Abstract

The invention discloses polyurethane cured acrylic resin anti-fogging and abrasion-resistant paint and a preparation method thereof. The paint is prepared from the following components in parts by weight: 130-190 parts of hydrophilic acrylic resin, 210-525 parts of blocked polyether-isocyanate used as curing agent and 2.00-5.00 parts of butyltin dilaurate used as catalyst, wherein the blocked polyether-isocyanate curing agent uses polypropylene glycol and isophorone diisocyanate as raw materials. The preparation method of the paint comprises the following steps: reacting to obtain polyether-isocyanate prepolymer and then reacting with methyl ethyl ketoxime used as sealing agent. The test result shows that the paint prepared by the method has high anti-fogging property, good transparency and abrasion resistance and low production cost; and under the premise of ensuring the good anti-fogging property of the paint, the surface wear resistance can be increased and the application prospectis wide.

Description

technical field

[0001] The invention relates to a polyurethane cured acrylate resin anti-fog wear-resistant coating and a preparation method thereof. Background technique

[0002] In daily life, transparent plastics are widely used, such as automobile lighting fixtures, plastic insulation greenhouses, etc., but in the process of use, as the environment changes in temperature and humidity, fogging will occur on the surface . Fog exists in the form of tiny water droplets. These small water droplets will refract and reflect light, thereby significantly reducing the light transmittance of transparent substrates and bringing inconvenience to life and work. For example, the lighting fixtures of automobiles will condense into fog on the inner wall of the light distribution mirror, and in severe cases, the light transmittance can be reduced by about 20%, which will affect the safety of driving. Therefore, how to solve the anti-fog problem of car lights has attracted extensive atte...
