Abstract

The invention relates to a waterproof polyurethane coating for woodware, which comprises the following components in parts by weight: 25 parts of polyurethane emulsion, 12 parts of bentonite, 5 parts of urea-formaldehyde resin, 6 parts of silicon dioxide, 5 parts of ethanol, 8 parts of epoxy resin, 4 parts of polyvinyl alcohol, 2 parts of formaldehyde, 2 parts of magnesium sulfate, 23 parts of talcum powder, 2 parts of a flame retardant, 12 parts of titanium dioxide, and 3 parts of a defoaming agent. Compared with the prior art, the waterproof polyurethane coating for woodware has good elasticity, low temperature flexibility, aging resistance, and no flowability at high temperature, and therefore, the quality of products can be improved, and the using temperature range of products can be expanded.

Description

technical field [0001] The invention relates to a chemical product, in particular to a waterproof polyurethane paint for woodware. Background technique [0002] Paint is also called paint. Refers to a class of liquid or solid materials that can form a thin film coated on the surface of an object under certain conditions to provide protection, decoration or other special functions (insulation, rust prevention, mildew resistance, heat resistance, etc.). Because most of the early paints used vegetable oil as the main raw material, they are also called paints. Now synthetic resins have mostly or completely replaced vegetable oils, so they are called paints. Waterproof coatings are composed of synthetic polymers, polymers and asphalt, polymers and cement as the main film-forming substances. Though this waterproof paint used raw material is cheap, makes product quality not guaranteed, can only produce low-grade waterproof paint, and existing production process is complicated, m...
