Example Embodiment

[0034] Taking Example 1 as an example, the preparation method of the first part of the product of the present invention is described, and the preparation steps are as follows:

[0035] (1) Add 2 / 3 of the total amount of pure water in the formula of Part A to the paint tank, then add dispersant BYK190 and part of defoamer 1-BYK024 while stirring, and stir and disperse 5 at a speed of 1500-1800 rpm. minutes to make a pre-dispersed water mixture;

[0036] (2) Slowly add fumed silica A200, titanium dioxide R-900, 1250 mesh heavy calcium carbonate and 800 mesh talc into the pre-dispersed water mixture, and disperse to the specified fineness at a speed of 1800-2000 rpm ;

[0037] (3) Slowly put water-based polyurethane PU800, water-based acrylic emulsion 6716 and water-based silica sol SPD30 into the paint-making tank at one time under stirring conditions;

[0038] (4) Mix the film-forming aid 1DPM, the film-forming aid 2DPNB and the remaining pure water evenly in advance, and slo...

Abstract

The invention belongs to the field of coatings and particularly relates to single-component white waterborne adhesion primer and a preparation method thereof. The high-performance and single-component white waterborne adhesion primer comprises a part A and water, wherein the part A comprises components in percentage by weight as follows: 25%-30% of waterborne single-component polyurethane, 8%-10% of a waterborne acrylic emulsion, 5%-10% of waterborne silica sol, 0.5%-1.0% of an adhesion promoter, 3.9%-6.3% of a function auxiliary, 31%-45% of filler and 10%-15% of water. The problems of hot sticking, cold shortness, high probability of cracking through thick coating and difficulty in adhesion of an oily substrate of conventional single-component white primer are solved, and the high-performance and single-component white waterborne adhesion primer contains few volatile organic solvents and meets the environment-friendly requirement.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a one-component water-based white adhesion primer and a preparation method thereof. Background technique [0002] With the increasing popularity of water-based wood coatings and the improvement of application technology, the terminal market has more and more requirements for the application of white wood coatings, especially wooden doors, cabinets, children's furniture, bookshelves, plus some flat furniture and so on. However, due to the problems of poor sealability, low hardness, poor fullness and high price of water-based wood coatings, the promotion and application of water-based wood coatings in the industry is limited to a certain extent, especially for difficult-to-use wood coatings such as large grease, many burrs, and heavy pigments. Closed substrates, such as Pinus sylvestris, rubber wood or MDF, etc., often require multiple constructions to seal the grease, burrs and...
