Abstract

The invention relates to a heat-insulating and heat-preserving polyurethane wood varnish and a preparation method thereof. The heat-insulating and heat-preserving wood varnish of the present invention is prepared from the following components according to the following weight ratios: 65-75 parts of wood short-oil alkyd resin, amino resin 8‑10 parts, hollow micro powder 1.5‑4.5 parts, polyurethane paint thinner 10‑25 parts, defoamer, 0.5‑1.5 parts, leveling agent 0.5‑1.5 parts, dispersant 0.5‑1.5 parts, matte powder 0.5‑3 parts 1-3 parts of p-toluenesulfonic acid, 0.5-1 parts of methyl ethyl ketone oxime. The heat-insulating and heat-preserving polyurethane wood paint prepared by the present invention is applied on the surface of wood with a commercially available curing agent to form various cross-linked structures, and the fixed hollow micro-powder is evenly distributed among them, which can delay the heat exchange speed between air and wood and play a good role in insulation. Heat and insulation effect.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a heat-insulating polyurethane wood varnish and a preparation method thereof. Background technique [0002] Wood paint refers to a type of resin paint coated on the surface of wood. Among them, polyurethane paint is widely used in wooden furniture and wooden floors because of its tough film, full luster, strong adhesion, water resistance and wear resistance. Paint does not have the effect of heat insulation, so wooden furniture and wooden floors are prone to problems such as cracking and deformation of wooden furniture and wooden floors when they are exposed to alternating cold and hot seasons during use. At present, it is particularly important to solve the heat insulation of polyurethane paint. Contents of the invention [0003] The invention provides a heat-insulating polyurethane wood varnish and a preparation method thereof, which solves the technical problem that the existing woo...
