preparation example Construction

[0045] The invention also discloses a preparation method of wood water paint, specifically comprising the following steps:

[0046] (1) Preparation of pre-cured paddle: weigh according to the formulation amount of the high-solid wood white primer described in any one of claims 1 to 6, first add water-based self-crosslinking acrylic acid emulsion to the container and start stirring, then Slowly add film-forming aids into the container under low-speed stirring, and start to disperse them at high speed after the addition is completed, and the dispersion time is 5-10 minutes;

[0047] (2) Add deionized water, pH adjuster and dispersant sequentially under low-speed stirring state. After the addition is completed, start to disperse them at a high speed. The dispersion time is 5-10 minutes. 800-mesh heavy calcium stirring at high speed, the stirring time is 15-20 minutes, and the mixed material paddle is obtained;

[0048] (3) Add the above-mentioned mixed slurry components into a g...

Embodiment 1

[0055] A kind of water-based paint for wood, which is prepared by the following raw material ratio in parts by mass: 32% of water-based self-crosslinking acrylic emulsion, 41% of film-forming aid, 45% of pigment, 0.5% of dispersant, and 0.3% of wetting agent , Leveling agent 0.3-1.5%, thickener 0.5%, pH regulator 0.15%, titanium dioxide 2.5%, 800 mesh heavy calcium 6%, deionized water balance;

[0056] Among them, the water-based self-crosslinking acrylic emulsion is self-crosslinking acrylic acid with a solid content of 45%, the leveling agent is an associative polyurethane thickening and leveling agent, and the thickener is a polyurethane thickener and dipropylene glycol methyl ether in a mass ratio of 2:1 uniform mixture, the dispersant is a wetting and dispersing agent, the wetting agent is a fluorosurfactant, and the film-forming aid is dipropylene glycol methyl ether.

Abstract

The invention discloses a woodenware water paint and a preparation method thereof. The woodenware water paint is prepared from the following raw materials by proportion: 30 to 40 percent of waterborneself-crosslinking acrylic emulsion, 40 to 50 percent of a coalescing agent, 45 to 55 percent of pigment, 0.3 to 1.5 percent of a dispersing agent, 0.1 to 1.0 percent of a wetting agent, 0.3 to 1.5 percent of a leveling agent, 0.1 to 1.0 percent of a thickening agent, 0.1 to 0.3 percent of a pH modifier, 1.5 to 5 percent of titanium dioxide, 3 to 15 percent of heavy calcium carbonate with 800 meshes and the balance of deionized water. The woodenware water paint prepared by the preparation method disclosed by the invention has the advantages of low cost, high hardness and the like; in addition,the woodenware water paint can seal tannic acid in wood and solve the problems of solid wood bloating and fiberboard bloating; construction procedure are effectively simplified and the coating cost is reduced; the woodenware water paint has great market application and popularization value.

Description

technical field [0001] The invention relates to the technical field of coating compositions, in particular to a water paint for woodware and a preparation method thereof. Background technique [0002] With people's increasing requirements for environmental protection and health, as well as the continuous improvement and strengthening of domestic and foreign environmental protection regulations, oil-based furniture paints have withdrawn from the market following environmental protection regulations, and water-based wood coatings have attracted more and more attention. Water-based wood coatings are a type of coating with water as the dispersion medium. They have the advantages of non-combustibility, non-toxicity, no pollution to the environment, and energy saving. The market prospect is broad. [0003] Moreover, on the premise of meeting the requirements of health and environmental protection, wood water-based paint has good filling, sanding and anti-cracking properties, and i...
