Embodiment example 1

[0030] The mass parts of each component of the anti-fog glue are: 15 parts of Cytec EBECRYL8415, 10 parts of Cytec EBECRYL8713B, 3 parts of benzoin dimethyl ether, 10 parts of nano-zinc oxide modified by polar groups, coupling agent 3-formaldehyde 1 part of acryloyloxypropyltrimethoxysilane, 2 parts of lithium amine salt antistatic agent, and 30 parts of solvent.

[0031] Spray the paint on the glass, adjust the outdoor temperature difference to 20°C, observe after 24 hours, there is no fog on the glass, and the anti-fog effect is good. The glass that has been sprayed with the paint is tested for abrasion resistance, and there is no obvious scratch. The glass is tested for impedance, and the impedance is 1010, which has a certain antistatic ability.

Embodiment example 2

[0033] The mass parts of each component of the anti-fog glue are: Cytec EBECRYL8602 10 parts, Changxing DR-050M1 15 parts, initiator 2-methyl-1-[-4-methylthio)phenyl]-2-morpholine 3 parts of base-1-acetone, 10 parts of nano silicon oxide modified by polar groups, 1 part of coupling agent 3-methacryloxypropyl triethoxysilane, 2 parts of carbon nanotube antistatic agent , 30 parts of solvent.

[0034] Spray the paint on the glass, adjust the outdoor temperature difference to 20°C, observe after 24 hours, there is no fog on the glass, and the anti-fog effect is good. The glass that has been sprayed with the paint is tested for abrasion resistance, and there is no obvious scratch. The glass is tested for impedance, and the impedance is 1010, which has a certain antistatic ability.

Embodiment example 3

[0036] The mass parts of each component of anti-fog glue are: 12 parts of Sartomer CN9013NS, 13 parts of EBECRYL8713B, 3 parts of initiator 2,4,6-trimethylbenzoyl-diphenylphosphine oxide, polar group 10 parts of modified nano-iron oxide, 1 part of coupling agent benzophenone, 4-benzoyl-4'-methyl-diphenyl sulfide, 2 parts of indium tin oxide antistatic agent, and 30 parts of solvent.

[0037] Spray the paint on the glass, adjust the outdoor temperature difference to 20°C, observe after 24 hours, there is no fog on the glass, and the anti-fog effect is good. The glass that has been sprayed with the paint is tested for abrasion resistance, and there is no obvious scratch. The impedance test of the glass shows that the impedance is 107, and the anti-static effect is good.

Abstract

The invention provides an ultraviolet curable anti-fog glue, which is characterized by comprising the following components by weight: 10-15 parts of first polyurethane acrylate; 10-15 parts of secondpolyurethane acrylate; 10-15 parts of polar group modified nanoparticles; 2-4 parts of an initiator; 1-3 parts an antistatic assistant; 1-3 parts of a coupling agent; and 30-50 parts of a solvent. Theultraviolet curable anti-fog glue provided by the invention adopts modified particles to combine photocurable resin, not only increases the anti-fog effect, but also improves the surface hardness andmechanical strength, and has excellent wear resistance. The coupling agent is added between the particles and the resin to well connect the particles and the resin, effectively improves the wear resistance of the resin, and at the same time improves the adhesion. The added antistatic agent endows the film with antistatic effect and prevents the film from adsorbing dust.

Description

technical field [0001] The invention relates to the technical field of glue coatings, in particular to an ultraviolet light curing anti-fog glue and a manufacturing method thereof. Background technique [0002] Anti-fog coating is a kind of functional coating. It is mostly suitable for the surface of transparent materials. Transparent substrates are indispensable materials in people's daily work, such as window glass in winter, car windshield glass, bathroom glass, plastic greenhouses Wait. Due to the temperature difference, there is often a certain temperature difference between the two sides of the transparent material. The saturated vapor pressure of the moisture on the surface with low temperature is lower than the vapor pressure of the surrounding environment, which will cause the water vapor to accumulate on the surface of the object and produce fog, which will affect the light transmittance of the transparent material and affect the line of sight. .
