Embodiment 1

[0031] (1) Preparation of 80% titanium dioxide slurry:

[0032] It is not easy to disperse when titanium white pulp is added directly to the wood lacquer system. Because the stable nano-alumina pulp is prepared in advance, it is added to the wood lacquer system during the let-down stage.

[0033] A. Titanium dioxide paste is prepared from the following raw materials in parts by weight:

[0034]

[0035] Mix and stir deionized water, defoamer, dispersant, and bactericide according to parts by weight, disperse at medium and low speed for 5-10 minutes, add titanium dioxide, disperse at high speed for 20-30 minutes, fineness ≤ 15um, and obtain titanium dioxide pulp.

[0036] The titanium dioxide content in the titanium dioxide slurry is 80%, and there is no delamination and coarsening phenomenon at 50°C / 7d.

[0037] Preparation of water-based one-component white flour material:

[0038]

[0039] Preparation:

[0040]Mix polyacrylic acid emulsion, polyurethane emulsion, d...

Embodiment 2

[0044] The preparation process is the same as in Example 1, except that the polyurethane emulsion in this example uses NEOREZ-986. Simultaneously present embodiment each component specific gravity is also different:

[0046]

Embodiment 3

[0048] The preparation process is the same as in Example 1, except that the water-based single-component white flour material polyacrylic acid emulsion of this example uses AC2524 as follows:

Abstract

The invention discloses a water-based single-component white surface material as well as a preparation method and application thereof. The water-based single-component white surface material is prepared from 30-40 parts of polyacrylic emulsion, 10-20 parts of polyurethane emulsion, 0.1-0.5 parts of an antifoaming agent, 1-5 parts of a wetting dispersant, 0.5-1.5 parts of a thickening agent, 25-30parts of titanium dioxide slurry, 1-3 parts of organic extinction powder, 3-5 parts of Fischer-Tropsch wax, 5-10 parts of a coalescing agent, 0.1-0.2 parts of a pH regulator, 0.1-0.2 part of a bactericide and 5-10 parts of water. The water-based single-component white surface material is high in paint film compactness, excellent in water resistance, high in fullness, good in construction performance and high in adhesive force, overcomes the defect that an existing water-based single-component white surface material is low in fullness, poor in compactness, poor in adhesive force, common in water resistance and the like, has a certain yellowing resistance effect and is a novel composite water-based environment-friendly product.

Description

technical field [0001] The invention belongs to the technical field of water-based wood lacquer, and in particular relates to a water-based single-component white surface material and its preparation method and application. Background technique [0002] With the further improvement of environmental protection regulations, in order to reduce the load on the earth, new low-VOC or zero-VOC emission coatings have become the focus of research and development. The research, development, promotion and application of water-based wood coatings have attracted more and more attention. In recent years, the research and development of water-based wood paint has achieved unprecedented development in our country. [0003] Water-based wood paint has been successfully applied in home decoration and ordinary furniture, and is expanding its market share. However, in some mid-to-high-end fields, such as bathrooms and cabinets, based on cost requirements, it is difficult for water-based one-com...
