Abstract

The invention relates to the technical field of paint, in particular to a UV wiping paint comprising following components in percentage by weight: 5-30 percent of TPGDA, 1-10 percent of TMPTA, 1-15 percent of HEMA, 1-10 percent of 2-EHA, 4-15 percent of photoinitiators, 40-60 percent of acrylic resin, 10-25 percent of toner, 0.1-0.5 percent of defoamer and 0.1-0.5 percent of anti-settling agent. The invention breaks through the characteristics of the traditional UV paint, modifies the UV paint, dyes in a wiping mode, and squeezes color into a wood pipe to enable the pipe to have deep color but the surface to only have light color so as to form three-dimensional grain effect.

Description

technical field [0001] The invention relates to the technical field of paint, in particular to a UV wiping paint. Background technique [0002] UV paint is the English abbreviation of Ultraviolet Curing Paint, that is, ultraviolet light curing paint, also known as photoinitiated coating, light curing coating. Different from PU, PE, NC and other paints named after the film-forming substances, it is automatically rolled and sprayed on the surface of the furniture board by machinery and equipment, and the initiator is decomposed under the irradiation of ultraviolet light (wavelength: 320-390nm) , generate free radicals, initiate resin reaction, and instantly solidify into a film. [0003] UV paint is different from PU paint, PE paint and NC paint commonly used by ordinary furniture companies. It not only has extremely high solid content, good hardness, and high transparency, but also has excellent yellowing resistance, long activation period, high efficiency, and low coating c...
