Abstract

The invention discloses ultraviolet curing white base paint and a construction process on the medium density fiber by using same. The ultraviolet curing white base paint comprises the following components in parts by weight: 20-35 parts of urethane acrylate, 20-30 parts of modified polyester acrylate, 15-20 parts of monomer, 10-20 parts of filler, 3-5 parts of photoinitiator, 0.5-1 part of anti-settling agent and 0.2-0.3 parts of defoaming agent. The construction process of the invention comprises the following steps: firstly spraying quick-drying water-based white base paint on a bottom plate, polishing, coating the ultraviolet curing white base paint on the bottom plate once, performing ultreviolet curing, polishing, and then coating polyurethane (PU) colored paint. Compared with the traditional process, the adhesive force of the base paint used in the construction process of the invention is not lower than that of the base paint used in the traditional process, or even higher; and the operation is simple, the construction time is short, the efficiency can be greatly increased, the energy can be saved and the emissions of the volatile organic compound (VOC) can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to the coating of paint on a medium-fiber board, in particular to an ultraviolet-curable white primer and a construction process using the white primer on a medium-fiber board. Background technique [0002] In recent years, cabinet furniture mostly uses MDF as the base material, on which different colors and colorful effects can be made. [0003] Coating paint on the MDF, the traditional process is to first make a PU sealing primer on the MDF, after polishing, do 2~3 PE white primers, after it is completely dry, polish and then apply PU color paint . This process involves a long time (at least 58 hours in rough calculation), high energy consumption, serious volatilization of organic solvents, great pollution to construction personnel and the environment, and low overall benefits and efficiency. [0004] UV curing coatings, referred to as UV coatings, also known as photoinitiated ...
