Abstract

The invention discloses a VOC-free coating for wood. The VOC-free coating is prepared from the following substances: an acrylic emulsion, water-dispersible polyisocyanate, epoxidized soybean oil, an antioxidant, sodium pyrophosphate, sodium dodecylbenzenesulfonate, polyvinyl alcohol, sodium carboxymethyl cellulose, an adsorption-enhancing filler, an antifoaming agent and water. The coating for wood in the invention has the following advantages: the varieties of the components of the coating are simple, and the components are reasonably matched; the coating is easy to produce and promote and has strong temperature resistance, corrosion resistance and weather resistance; and a formed film has good mechanical quality, high stability and no harmful volatile organic compounds, is green and safe, and has strong market competitiveness.

Description

technical field [0001] The invention belongs to the technical field of paint processing and treatment, and particularly relates to a zero-VOC paint for wood. Background technique [0002] Wood is one of the essential materials in people's life now. Such as building decoration, wicker weaving, ships and bridges and other industries need a lot of wood raw materials. In the above-mentioned industries, wood needs to be coated with coatings in order to improve the service life, aesthetics, and application performance of the wood. In home decoration, because wood is in direct contact with people's living environment, the wood coated with paint usually emits harmful substances, which will damage health in the long run. With the strengthening of people's awareness of environmental protection, high-quality non-volatile coatings are becoming more and more more respected. [0003] Application No.: 201610679192.2 discloses a zero VOC volatilization water-based woodware coating, where...
