Problems solved by technology

[0003] Among the existing water-based coatings, the production cost of acrylic coatings is lower, and the film-forming properties, adhesion, weather resistance and stain resistance are better, but it has the disadvantages of low hardness and "hot stickiness and cold brittleness"; High, the water resistance and chemical resistance of the coating film are not good, but it has excellent wear resistance and flexibility; water-based fluorocarbon coatings have excellent gloss and color retention, super weather resistance, water resistance, anti-corrosion Stain, flame and chemical resistance with excellent adhesion and aging resistance

Abstract

The invention discloses a water-based wood coating with antibacterial, anti-fouling, mosquito-repellent and insect-repellent effects, and preparation method thereof. The water-based wood coating comprises, by weight, 24-30 parts of water-based polyacrylate, 7-12 parts of water-based polyurethane, 1.5-2.5 parts of water-based fluorocarbon resin, 0.5-0.8 part of a cosolvent, 3-6 parts of deionized water, 1.0-2.5 parts of silicone oil, 0.1-0.3 part of nanometer zinc oxide, 0.6-1.0 part of multiply modified nanometer titanium dioxide, 0.05-0.15 part of a surfactant and 0.6-1.8 parts of anhydrous ethanol. The water-based wood coating of the invention has good antibacterial, anti-fouling, anti-insect and mosquito-repellent effects; and a paint film formed by the coating also has good adhesion, toughness, water resistance, wear resistance, weather resistance and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an antibacterial, anti-fouling, mosquito-repelling and insect-repelling water-based wood coating and a preparation method thereof. Background technique [0002] At present, due to the increasingly serious pressure of environmental protection, the country has introduced a number of emission reduction policies, and the "water-based" of wood coatings is imminent. In Britain, Germany and other countries, water-based wood coatings have occupied 80%-90% of the market share in the entire coating industry, but in my country it is less than 20%. Water-based wood coatings use water as the medium and basically do not contain toxic and harmful substances such as formaldehyde, benzene series, VOC, and heavy metals. They can improve the indoor environment and living comfort, and have the advantages of energy saving, emission reduction, low-carbon environmental protection, etc., and the market...
