Aerogel modified LED-UV scalding-resistant paint and preparation method and using method thereof

Abstract

The invention provides an aerogel modified LED-UV scalding-resistant paint which is obtained by mixing, by weight, 30-45 parts of 3 functional modified O-cresol formaldehyde epoxy acrylate resin, 15-20 parts of low-energy-curing special functional acrylic resin, 5-10 parts of 8 functional hyperbranched polyester acrylic resin, 10-23 parts of monomer, 4-5 parts of photoinitiator, 0.3-0.5 part of wetting dispersant, 0.3-0.5 part of defoamer and 12-20 parts of nano silicon dioxide aerogel slurry. The LED-UV paint is high in low-energy curing efficiency, environment-friendly, free of VOC emission,convenient in construction and good in heat-resistant and scalding-resistant performance; a LED-UV lamp is used in the process of curing and drying of the paint, and an obtained film is high in hardness, high in resistance to heat and scalding, smooth in surface and good in hand feel. The invention further provides a preparation method and a using method of the LED-UV scalding-resistant paint.

Description

technical field [0001] The invention relates to the technical field of functional coatings, in particular to an airgel-modified LED-UV heat-resistant coating and a preparation method and application method thereof. Background technique [0002] Furniture products used in daily life, such as office desks, tea tables, dining tables, bar counters, etc., are often damaged by high temperatures such as boiling water and cigarette butts, resulting in damage to the surface of the paint film that cannot be repaired and can only be restored by repainting As it is, it seriously affects the convenience and service life of the furniture. [0003] In order to solve the above problems, many companies have successively developed various heat-resistant coatings such as water-based, oil-based, traditional light-cured and PU two-component coatings, but these products have many defects, for example: water-based paint film plumpness is worse than oil-based, At the same time, it has the disadvan...

Problems solved by technology

[0002] Furniture products used in daily life, such as office tables, tea tables, dining tables, bar counters, etc., often encounter high temperature damage such as boiling water and cigarette butts, resulting in damage to the surface of the paint film that cannot be repaired and can only be restored by repainting As it is, it seriously affects the convenience and service life of the furniture

[0003] In order to solve the above problems, many companies have successively developed various heat-resistant coatings such as water-based, oil-based, traditional light-cured and PU two-component coatings, but these products have many defects, for example: water-based paint film fullness is worse than oil-based, At the same time, it has the disadvantages of insufficient hardness of the paint film and poor heat resistance; the PU two-component oily coating takes a long time to dry, the paint film is poorly resistant to cigarette burns, and the construction needs to add curing agents and thinners for construction, and VOC emissions are poor in environmental protection; traditional UV light Although the cured coating has the advantages of high film hardness, good wear resistance and high curing efficiency, it must use high-pressure mercury lamp luminescent radiation drying equipment to complete the cross-linking and curing reaction in the drying process, complete the film-forming and curing of the paint, and high-pressure mercury Due to the high power (generally 80W / cm), the lamp has strong light intensity and brightness, strong heat radiation (it will increase the surface temperature of the workpiece by about 20°C when it shines on the surface of the workpiece), and it will generate ozone when working, which requires a matching cooling system.
