Abstract

The invention relates to a high-adhesion water-based electrostatic white finish paint. The white finish paint comprises, by mass, 45-70% of an aqueous emulsion, 16-32% of titanium dioxide, 0.1-3% of matt powder, 0.5-3% of a wax powder or wax emulsion, 3-8% of an anti-scratch functional filler, 0.5-3% of a dispersion wetting agent, 1-6% of a film forming aid, 0.3-5% of an anti-sagging aid, 0.2-2% of a thickener, 0.2-3% of a leveling agent, 0.2-2.0% of a base material wetting agent, 0.5-1.5% of other aids and 1-15% of water. The product disclosed in the invention meets the requirements of GB / T 23999-2008, and is safe and environmentally friendly, has the advantages of good leveling property, high electrostatic adsorbability, good wettability for a base material, good wear resistance, good scratch resistance, good chemical resistance, fine and smooth paint film, easiness in production and manufacturing, and improved construction safety in the coating process.

Description

technical field [0001] The invention belongs to the field of wood ware lacquer, and in particular relates to a high-adhesion water-based electrostatic white finish paint for wood ware decoration and a preparation method thereof. [0002] technical background [0003] The common coating methods of water-based paint are: dip coating, brush coating, roller coating, spray coating, etc. As a coating method that can best systemize the surface effect of decorative materials, spraying has developed airless spraying, air spraying, mixed air spraying, etc. Among them, the coatings with high coating efficiency and high paint utilization include: reciprocating machine Air-mixed spraying, electrostatic spraying. [0004] Electrostatic spraying is widely used in: metal (automobiles, containers, instruments, etc.), plastics (subway, home appliances, etc.), wood (pine furniture, bamboo furniture, etc.). As the mainstream product of export furniture: cabinet furniture, the common coating ma...
