Problems solved by technology

[0003] Although LED cold light curing has many advantages, the attenuation of light is also obvious. It is difficult to cure when the distance is more than 30cm, so it is difficult to realize the curing of heterogeneous parts and large parts, which makes it difficult to promote LED, especially in the furniture industry.
[0004] For example, the published patent CN108690389 A discloses a water-based wood varnish that can be light-cured by LED lamps, CN 108517141 A LED discloses a light-curable water-based antibacterial wood varnish, and CN 107227056 A discloses a water-based antibacterial wood varnish that can be cured under any weak light source. The paint that can be cured into a film for wood surface coating, and CN 108410347 A discloses a kind of LED light source water-based UV paint. These existing paints for wood are cured to ensure the curing effect. The curing distance is less than 30cm. Unable to meet the curing needs of heterosexual pieces and large pieces of furniture

Abstract

The invention belongs to the technical field of wood coatings, and relates to a preparation method of a remotely-cured water-based LED (light-emitting diode) blue-light UV (ultraviolet) wood coating. Comprising the following components in parts by weight: 80-100 parts of water-based UV cured resin, 5-10 parts of a UV monomer, 0.1-0.3 part of a pH regulator, 5-10 parts of water-based normal-temperature self-crosslinking resin, 5-10 parts of water-based inorganic nano resin, 0.2-0.5 part of water-based polyamide wax, 0.2-0.6 part of a water-based base material wetting agent, 3-6 parts of a photoinitiator, 0.1-0.3 part of a water-based defoaming agent, 0.3-1.5 parts of a water-based thickening agent, 0.2-0.6 part of a water-based flatting agent and 5-8 parts of water-based hardening scratch-resistant hand feeling wax emulsion. And 5-10 parts of deionized water. According to the invention, reasonable compatibility of the components is achieved through optimization and improvement of a formula, so that the LED curing distance can basically break through 70cm, and the problems of oxygen resistance and light attenuation are solved; the performance test of the wood coating at the distance of 60/70cm shows that the performance of the coating is not influenced while long-distance curing is realized, and the wood coating is suitable for spray coating and roll coating.

Description

technical field [0001] The invention relates to the technical field of woodware coatings, in particular to a preparation method of a long-distance curing water-based LED blue light UV woodware coating. Background technique [0002] At present, wood furniture coatings are divided into two categories: oil-based and water-based. With environmental protection and excessive formaldehyde and benzene, oil-based coatings are no longer suitable for home improvement requirements, especially for whole-house custom furniture. Water-based coatings just make up for the shortcomings of oil. Water-based wood coatings include water-based acrylic coatings, water-based polyurethane coatings, water-based alkyd coatings, water-based epoxy coatings, sol-gel coatings, and water-based light-curing coatings. The curing methods of water-based light-curing coatings include mercury lamp curing, halogen lamp curing, LED cold light source curing, mercury lamp curing and halogen lamp curing due to high en...
