Abstract

The present invention discloses a white composition for ultraviolet solidification. The composition comprises the components of the weight percentages: (1) 10 percent to 40 percent of epoxy acrylate containing carboxyl; (2) 5 percent to 20 percent of polyurethane acrylic ester containing carboxyl; (3) 10 percent to 30 percent of super branching polyester acrylate; (4) 15 percent to 40 percent of acrylic monomer of single- or multi-functional degree; (5) 8 percent to 20 percent of titanium dioxide; (6) 1 percent to 8 percent of light initiator; (7) 0.5 percent to 3 percent of auxiliary aid; and (8) 0.5 percent to 10 percent of adhesive assistant agent. The construction process of the coating of the present invention is simple; the coating can be widely used (not limited) for various density boards, and solid plate materials. After the coating is solidified by ultraviolet irradiation, the coating film has good adhesive capability, high hardness, good covering capability and leveling performances.

Description

technical field [0001] The invention relates to an ultraviolet light-curable white composition, which can be widely used in various density boards and solid wood boards, and has good hardness and good hiding power. Background technique [0002] UV curing materials have been widely used in wood, plastic, metal, paper and other industries due to their high efficiency, energy saving and environmental protection. Due to the absorption of ultraviolet light by inorganic pigments, especially titanium dioxide (titanium dioxide), it has always been difficult to design and prepare UV-curable thick coating materials that can be completely covered. At present, the UV curing materials used commercially are mainly transparent. CN1225642A discloses a photosensitive composition and white paint. This invention adopts a special photosensitive composition, which is colorless and transparent at room temperature, but can It is cured and whitened by ultraviolet light to produce a white substance...
