Abstract

The invention discloses a bi-component waterborne woodware waterproof coating and belongs to the technical field of building materials. A preparation method of the coating includes: putting, by weight, 50-60 parts of waterborne polyurethane emulsion, 2-3 parts of mixed enzyme liquid, 3-5 parts of organic acid, 8-10 parts of bacterial cellulose, 5-6 parts of rare earth, 5-6 parts of defoamer, 5-6 parts of thickener, 8-10 parts of modified sodium alginate liquid, 5-6 parts of coated sodium peroxide and 20-30 parts of water into a 3# beaker, and stirring and mixing at rotating speed of 300-500r / min for 30-50min to obtain a component A; putting, by weight, 10-20 parts of ethyl orthosilicate, 10-20 parts of nano alumina powder, 10-20 parts of sodium fluosilicate and 5-8 parts of animal bone powder into a ball mill, and ball mill mixing for 30-50min to obtain a component B; separately packaging the component A and the component B to obtain the bi-component waterborne woodware waterproof coating. The coating has excellent mechanical performance and waterproof performance.

Description

technical field [0001] The invention discloses a two-component water-based water-resistant paint for woodware, which belongs to the technical field of building materials. Background technique [0002] Wood coatings can protect, decorate and beautify wood. According to different construction techniques, different application fields, and different technical requirements, the requirements for water resistance of water-based wood coatings are also different. Including early water resistance, long-term water resistance, water whitening resistance, water whitening recovery resistance, boiling water resistance and so on. This is not only a comprehensive assessment of the water resistance of water-based wood coatings, but also a simulation of the actual use environment. Early water resistance is very important for exterior waterborne wood coatings. Early water resistance means that the solvent in the coating film has not been completely volatilized, and it has not been completely...
