Problems solved by technology

When coating products with deep wood grain eyes to highlight wood grain, the wood eye and wood diameter cannot be penetrated in a directional way, resulting in oil accumulation in the wood eye and no oil in the wood diameter, and finally the beautiful pattern of the wood grain cannot be reflected, and There will be various defects such as sagging, pinholes, and sagging during painting, which will affect the painting efficiency and product production effect

Abstract

The invention discloses white polyurethane paint capable of highly highlighting wood grains. The paint is prepared from a polyurethane colored paint host, a curing agent and a diluent in the weight ratio being 1:0.5:(0.5-0.8). According to the formula of the polyurethane colored paint host, self-made high-permeability alkyd resin, aids and powder are matched, and a paint film of the white polyurethane paint can realize quick and directional permeation leveling, cannot produce paint film sinking caused by bubble bursting, has no black spots and makes wood grains smooth and wood diameters flat under the dual effects of permeation sealing and permeation leveling. The wood grains can be displayed stereoscopically and obviously after following coating while wood coating is performed.

Description

technical field [0001] The invention relates to a polyurethane white paint, in particular to a highly prominent wood grain polyurethane white paint. Background technique [0002] Now the obvious wood grain paint coating of wood products usually adopts conventional polyurethane color paint to be equipped with curing agent for coating production. When coating products with deep wood grain eyes to highlight wood grain, the wood eye and wood diameter cannot be penetrated in a directional way, resulting in oil accumulation in the wood eye and no oil in the wood diameter, and finally the beautiful pattern of the wood grain cannot be reflected, and There will be various defects such as sagging, pinholes, and filth during painting, which will affect the painting efficiency and product production effect. [0003] Therefore need to develop a kind of highly prominent wood grain polyurethane white paint that can show the three-dimensional effect of wood grain when wood products are exp...
