Ultraviolet-curing-based waterproof coating primer for furniture and production method thereof

Abstract

The invention discloses a UV-cured waterproof coating primer for furniture and a production method thereof, which belong to the technical field of chemical industry. The components in parts by weight include: 4-7 parts of epoxy resin, 75-90 parts of zinc powder, silicon-containing 3-5 parts of nano additives, 2-3 parts of anti-sedimentation agent, 5-12 parts of organic solvent, 15-35 parts of modified polyester acrylate, 10-25 parts of monomer, 25-45 parts of filler, light 2 to 7 parts of initiator, 0.8 to 1.2 parts of anti-settling agent, and 0.5 to 0.7 parts of defoamer, the UV-cured waterproof coating primer for furniture of the present invention can improve adhesion and salt spray resistance, which is better than traditional technology Excellent primer adhesion, simple operation, short time-consuming, greatly improved efficiency, saved energy, greatly reduced VOC emissions, and avoided bulging and detachment after construction.

Description

Technical field [0001] The invention relates to an ultraviolet curing-based waterproof coating primer for furniture and a production method thereof, and belongs to the technical field of chemical engineering. Background technique [0002] In the prior art, when the metal zinc content of the dry film based on the epoxy zinc-rich primer is ≥70%, the coating adhesion, impact resistance and other mechanical properties will decrease as the zinc content increases, and the salt spray resistance will also be improved. This will affect the coating easily damaged by external forces during the construction process and return rust, increasing the workload of repair, even if the coating is not damaged, it will eventually affect the service life. [0003] Ultraviolet light curing technology is a kind of automatic roller coating, curtain coating or spraying on the furniture board through the machine and equipment. Under the irradiation of ultraviolet light, it promotes the decomposition of the ph...

Problems solved by technology

[0002] In the prior art, when the metal zinc content of the dry film based on epoxy zinc-rich primer is ≥70%, the mechanical properties such as coating adhesion and impact resistance will decrease with the increase of zinc content, and the salt spray resistance will also decrease. This will affect the construction process. The coating is easily damaged by external forces and rust will appear, which will increase the workload of repair. Even if the coating is not damaged, it will eventually affect the service life
