Ultraviolet (UV)-hardened primer

Abstract

The invention discloses a kind of ultraviolet (UV)-hardened primer, which comprises the following ingredients by weight percent: 50 to 65 percent of 100% UV resin, 0.1 to 0.3 percent of defoaming agent, 0.2 to 0.4 percent of dispersing agent, 6 to 10 percent of stuffing, 2.5 to 4 percent of initiator, 0.3 to 0.7 percent of anti-settling agent and the balance of monomer; the 100% UV-resin is quadri-functional polyurethane acrylic resin, tri-functional modified epoxy acrylic resin or mixture of the quadric-functional polyurethane acrylic resin and the tri-functional modified epoxy acrylic resin; the monomer is acrylate, modified acrylate or mixture of the acrylate and the modified acrylate; and the stuffing is the organism modified high-pure and high-hardness glass powder or quartz powder. The paint has good flexibility, has high hardness and good flexibility, also has certain tensile strength and can improve the hardness of furniture, floor or soft lumber so as to form durable protection for the surface of the wooden furniture and the floor board and to prolong the service life.

Description

technical field [0001] The invention relates to a UV-light curing wood coating, in particular to a tough UV-hardening primer. Background technique [0002] UV is the English abbreviation of Ultraviolet (ultraviolet), and UV paint is ultraviolet light curing paint. Ordinary wood boards, silicon-calcium boards and other boards are painted with UV paint, and then dried by a UV light curing machine to form stone boards. They have bright surface treatment, bright color, strong visual impact, wear resistance, and strong chemical resistance. Long service life, no discoloration, easy to clean, is an ideal plate maintenance treatment process. The surfaces of existing wooden furniture, wooden floors and other wood products all adopt UV paint, that is, UV curing paint maintenance treatment process. However, due to the poor toughness and hardness of ordinary UV-curable primers and limited wear resistance, the surface of wooden furniture, wooden floors and other wood products is prone ...

AI Technical Summary

Problems solved by technology

However, due to the poor toughness and hardness of ordinary UV-curable primers and limited wear resistance, the surface of wooden furniture, wooden floors and other wood products is prone to scratches or scratches. In order to avoid this situation, consumers usually use Be careful, but still can not avoid scratches

Existing wood surface coatings do not meet the requirements in terms of strength and toughness, and at the same time, it is difficult to achieve high-quality products stably in the national standard test

This directly affects the beauty and service life of wooden furniture and wooden floors
