Embodiment 1

[0039] This embodiment provides a water-based two-component bright white topcoat, its composition and specific preparation process are as follows:

[0040] A component:

[0041] First add 6.5kg of water-based hydroxyl polyacrylic acid dispersion 2470, 0.5kg of water, 0.02kg of pH regulator AMP95 into the dispersion container, adjust the pH to 8-8.5, 0.3kg of dipropylene glycol butyl ether DPNB, 0.2kg of dipropylene glycol methyl ether DPM, 0.05 Add kg defoamer BYK024, 0.1kg surfactant F204E, 0.2kg acrylate leveling agent PW336 into the dispersion container in turn, stir well and add 1.2kg titanium white paste (70%), 0.05kg thickener RM2050D to disperse for 15 minutes , Stir 1kg of water evenly.

[0042] B component:

[0043] Hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI).

[0044] During construction, the ratio of component A and component B is 100:14 and mixed evenly.

Embodiment 2

[0046] The present embodiment provides a kind of water-based two-component bright white finish paint, and the preparation process is the same as in Example 1, and the difference is that the composition of the water-based two-component bright white finish paint of the present embodiment is as follows:

[0047] A component:

[0048]

[0049]

[0050] Component B: Hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI).

[0051] During construction, mix evenly according to the weight ratio of component A and component B at 100:20.

Embodiment 3

[0053]This embodiment provides a kind of water-based two-component bright white finish paint, and the preparation process is the same as in Example 1, and the difference is that the composition of the water-based two-component bright white finish paint of the present embodiment is as follows (water is divided into two parts and used):

[0054] A component:

[0055]

[0056]

[0057] Component B: Hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI).

[0058] During construction, mix evenly according to the weight ratio of component A and component B at 100:15.

Abstract

The invention provides waterborne bi-component bright white finish. The waterborne bi-component bright white finish is prepared from, by weight, a component A and a component B. The component A is prepared from, by weight, 60-70 parts of waterborne hydroxyl polyacrylic acid dispersions or waterborne modified acrylic resin, 0.4-1 part of defoaming agent, 0.5-1.5 parts of surface active agent, 0.5-2.5 parts of flattening agent, 0.2-0.5 part of thickening agent, 10-15 parts of sizing agent and 5-16 parts of water. The component b is prepared from, by weight, hydrophilic aliphatic series aliphatic series. The weight ratio of the component A and the component B is 100:(14-25), wherein the preferential weight ratio is 100:(14-20). The waterborne bi-component bright white finish is excellent in materialization, high in fullness, gloss and construction performance, strong in adhesive force and long in constructability time. Most importantly, health of constructors can not be hurt, and the waterborne bi-component bright white finish is a waterborne environment-friendly product.

Description

technical field [0001] The invention relates to a bright white finish paint, in particular to a water-based two-component bright white finish paint and its application. Background technique [0002] Most of the bright white surfaces of high-end furniture on the market are mainly solvent-based paints. At present, the main coating systems used are mostly solvent-based polyurethane (PU) paints and solvent-based nitro (NC) paints. Although the above product systems have high gloss and good hardness, they all contain a large amount of organic solvents, and their environmental protection is their biggest weakness; [0003] Water-based wood coatings are currently recognized as the most environmentally friendly coating type, featuring ultra-low volatile organic compound content (VOC), which greatly reduces the use of organic solvents. It is of great significance to develop a high-performance, high-hardness, high-fullness that can not only meet the high-end furniture market, but als...
