Abstract

The invention relates to the technical field of coating material production, in particular to a modified acrylic coating material and a preparation method thereof, a glossiness adjusting method and anapplication. The modified acrylic coating material is mainly prepared from the following components in parts by weight: 10-20 parts of alkyd resin, 35-50 parts of acrylic resin, 2-3 parts of proprylene glycol monomethyl ether, 1-2 parts of dipropyl methanol butyl ether, 0.5-2 parts of water, 20-26 parts of color paste, 3-8 parts of auxiliary agents and 0.1-40 parts of polyaldehyde resin solution,wherein the polyaldehyde resin solution is mainly prepared by dissolving polyaldehyde resin in a composite solvent. The coating material adopts the polyaldehyde resin, which comprises multiple N, C =O,-OH groups with high molar refractive index and a saturated cyclic structure, and the polyaldehyde resin is dissolved in the composite solvent in advance to promote the polyaldehyde resin to be well dispersed in an aqueous paint system, so that the coating layer prepared by the coating material has high gloss, hardness, degradation resistance, weather resistance, water resistance and heat resistance.

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to a modified acrylic paint, a preparation method thereof, a gloss adjustment method and application thereof. Background technique [0002] The surface coating of high-speed rail, new energy vehicles, passenger cars, buses, trucks, mechanical equipment, hardware components, etc. all require certain paint aesthetics, and this paint aesthetics is closely related to culture and habits. For chemical researchers, more attention is paid to the physical properties of coatings, but less attention is paid to the aesthetics of coatings. As everyone knows, the aesthetics of coatings in the market largely affects consumer choices, even more important than physical properties. Coating aesthetics are diverse, including tactile aesthetics and visual aesthetics. Tactile aesthetics includes thickness, wetness, slippery, etc.; visual aesthetics includes color, texture, texture, fullness, g...
