Problems solved by technology

There are many situations in daily life that will face the phenomenon of fogging, for example: when the weather is wet and cold, the windows of the car or the glass curtain of the building are easy to fog and affect the sight of the driver or the indoor people; when the temperature is cold, the helmet of the motorcyclist Lenses or goggles are prone to fogging due to breathing; and transparent protective covers worn by medical staff, because breathing often fogs up on the protective cover, affecting vision
Therefore, the fogging phenomenon on the surface of objects will cause inconvenience to users in many usage scenarios, and it is of great significance to develop materials with excellent anti-fogging properties

preparation example Construction

[0036] The present invention also provides the preparation method of this high-definition anti-fog coating, and it comprises the following steps:

[0037] 1) The solvent is divided into four parts: the first part of solvent, the second part of solvent, the third part of solvent and the fourth part of solvent;

[0038] 2) Stir and dissolve the methallyl ether, polyester acrylic monomer, and polyurethane-modified acrylic resin prepolymer with the first solvent at 65-120° C. for 1-3 hours, and then lower the temperature to 40° C. -55 ℃, and keep warm, obtain the first mixture;

[0039] Stirring and dissolving the tetraethylamine perfluorooctane sulfonate and sodium 3-prop-2-enoyloxypropane-1-sulfonate with the second solvent for 15-60 minutes to obtain a second mixture;

[0040] adding nano-copper, nano-titanium dioxide, and nano-alumina to the third solvent, and stirring for 15-60 minutes to obtain a third mixture;

[0041] adding the coupling agent and the leveling agent to t...

Embodiment 1

[0047] A high-definition anti-fog coating, which includes the following raw materials in parts by weight:

[0048]

[0049] Wherein, the auxiliary agent includes 2 parts by weight of leveling agent, 3 parts by weight of coupling agent, 3 parts by weight of curing agent and 52 parts by weight of solvent. The leveling agent is a mixture of a fluorine-modified acrylic leveling agent and an organically modified polysiloxane. The coupling agent is a mixture of glycidyl ether silane and vinyl silane. The curing agent is diaminocyclohexane. The solvent is isopropanol.

Abstract

The invention discloses a high-definition anti-fog coating, which is prepared from the following raw materials in parts by weight: 20 to 60 parts of methyl allyl ether; 30-70 parts by weight of a polyester acrylic monomer; 30 to 70 parts by weight of a polyurethane modified acrylic resin prepolymer; 1 to 10 parts by weight of perfluorooctane sulfonate tetraethylamine; 1-10 parts by weight of 3-propane-2-enoyloxypropane-1-sodium sulfonate, 0.5 to 15 parts by weight of nano copper, 0.5 to 15 parts by weight of nano titanium dioxide, 0.5 to 15 parts by weight of nano aluminum oxide and 20-70 parts by weight of an auxiliary agent. According to the high-definition anti-fog coating, the surface of a base material is coated with the coating to form a coating layer, the base material can obtain excellent anti-fog performance, and the formed coating layer has high light transmission performance, good bonding strength, high weather resistance and high water resistance and has good market application prospects.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a high-definition anti-fog coating. Background technique [0002] Transparent substrates such as glass, transparent plastic, etc., due to internal and external temperature changes during use, cause water vapor in the air to condense on the surface of the substrate, forming an opaque "fog". There are many situations in daily life that will face the phenomenon of fogging, for example: when the weather is wet and cold, the windows of the car or the glass curtain of the building are easy to fog and affect the sight of the driver or the indoor people; when the temperature is cold, the helmet of the motorcyclist Lenses or goggles are prone to fogging due to breathing; as well as transparent protective covers worn by medical staff, breathing often fogs up on the protective cover, affecting vision. Therefore, the fogging phenomenon on the surface of objects will cause inconvenience to...
