Problems solved by technology

[0002] Water-based wood coatings are widely used in the coating of indoor wood products because of their safety, environmental protection and non-toxicity. However, some indoor wood products are spliced ​​by adhesives and contain a large amount of formaldehyde. However, the existing water-based wood coatings cannot remove such formaldehyde, resulting in long-term Indoor volatilization damages health

Abstract

The invention discloses a formaldehyde degrading waterborne wood coating. The coating comprises the following raw materials: 75.0-85.0 parts of waterborne polyurethane emulsion, 1.0-2.0 parts of defoaming agents, 4.0-6.0 parts of film-forming additives, 0.3-0.5 part of dispersing agents, 0.2-0.4 part of wetting agents, 0.5-1.0 part of anatase nano titanium dioxide, 0.2-0.3 part of levelling agents, 0.2-0.4 part of bactericides, 1.0-1.5 parts of thickening agents and 5.0-10.0 parts of water by weight. The product is safe, non-radiative and nontoxic, does not cause secondary pollution, has antibacterial and sterilization functions and very stable properties and does not participate in reactions. The product can transform light energy into chemical energy under light to excite surrounding water molecules and oxygen molecules to undergo ionization. The product effectively degrades harmful substances in the air, such as formaldehyde, through photoemission.

Description

technical field [0001] The invention relates to a water-based wood coating for interior decoration, in particular to a water-based wood coating that degrades formaldehyde in the air through photoelectric effect. Background technique [0002] Water-based wood coatings are widely used in the coating of indoor wood products because of their safety, environmental protection and non-toxicity. However, some indoor wood products are spliced ​​by adhesives and contain a large amount of formaldehyde. However, the existing water-based wood coatings cannot remove such formaldehyde, resulting in long-term Indoor volatilization is harmful to health. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the existing defects and provide a water-based wood coating that degrades formaldehyde. [0004] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions: [0005...
