Embodiment 1

[0050] Prepare the water-based black wood finish of vegetable oil modification by the formula weight part of table 3, comprise the following steps:

[0051] a) Prepare raw materials according to the weight parts set by the formula, put water, wetting and dispersing agent, black paste ColanylBlackN, and defoamer into the container and stir at a high speed of 1200-1400 rpm, stir for 15 minutes, and then reduce the speed to 1000 rpm , while stirring, add aliphatic modified polyurethane dispersion and hardening resin, after stirring for 10 minutes, add antifreeze, wax emulsion, plant-based composite nano-bactericidal powder and stir for 5 minutes, reduce the speed to 600 rpm, add pH adjustment Adjust the pH value to 8 with the agent, and add the thickener to adjust the viscosity required by the customer.

[0052] b) Detection-filter-package-sample retention.

Abstract

The invention discloses water-based wood paint modified by vegetable oil and a preparation method of the water-based wood paint. The water-based wood paint is prepared from, by weight, 60-85 parts of aliphatic series modified polyurethane dispersoid, 1-3 parts of hardness-enhancing resin, 7-12 parts of water, 1-3 parts of wax emulsion, 2-5 parts of coalescing agents, 0.2-0.7 part of wetting dispersant, 0.1-0.5 part of flatting agents, 0.2-0.7 part of deforming agents, 1-2 parts of antifreezing agents and 0.3-0.7 part of thickening agents. According to the water-based wood paint modified by the vegetable oil and the preparation method of the water-based wood paint, formula adjustment is utilized, the environment-friendly type water-based hardness-enhancing resin is matched, and the hardness-enhancing resin comprises solvent-free water-based modified aldehyde ketone resin dispersoid. The water-based wood paint can reach or exceeds oil-based wood paint in physical and chemical technical index, and all comprehensive properties are excellent.

Description

technical field [0001] The invention relates to the technical field of water-based wood lacquer, and particularly discloses a vegetable oil-modified water-based wood lacquer and a preparation method thereof. Background technique [0002] Polyurethane coatings have various excellent properties and are widely used in coatings and paints. Solvent-based polyurethane paint is not environmentally friendly due to the volatility and toxicity of the solvent, and is gradually replaced by water-based polyurethane paint. [0003] Polyurethane water-based paint can also be used in wood coatings, the use of aminosilane coupling agent modified polyurethane aqueous emulsion can improve the adhesion, water resistance and mechanical properties of the corresponding coating ("The development of aminosilane coupling agent modified water-based polyurethane wood coatings ", Hou Menghua, etc., decoration materials). However, the hardness, corrosion resistance, solvent resistance, glossiness, scra...
