Abstract

The invention relates to the field of wood coatings, in particular to an ultraviolet curing high hardness wood coating and a preparation method thereof. The ultraviolet curing high hardness wood coating includes, by weight parts, 30-70 parts of oligomer, 10-30 parts of thinner, 2-5 parts of photoinitiator, 5-10 parts of the filler and 1-5 parts of functional auxiliary. Compared with a UV curable material for conventional wood coatings, the material can reach a hardness of 78 Shore D or more, and can reach a hardness as high as 90 Shore D, and has excellent properties such as high hardness, high tensile strength and high light transmittance and the like. Therefore, the ultraviolet curing high hardness wood coating has a very broad application prospect and can be widely applied in the fieldof wood coating.

Description

technical field [0001] The invention relates to the field of wood coatings, in particular to an ultraviolet-cured high-hardness wood coating and a preparation method thereof. Background technique [0002] Ultraviolet light curing is also called UV curing. The advantages of UV coatings such as fast curing, high efficiency, low VOC, and energy saving make it have the vitality of rapid development. Over the past 20 years in China, UV curable coatings have been growing at double digits. With its advantages of fast curing, low pollution and energy saving, UV curable coatings are used in wood, ink, plastic, adhesives, printed artwork, printed circuit boards, electronic component packaging materials, canned iron printing, metal, stone, cement products, fabrics, leather , Glass and other fields have been applied. UV curable wood coatings have high coating efficiency and are suitable for assembly line production, especially after curing, the coating film has excellent performance, ...
