[0032] Correspondingly, the embodiment of the present invention also provides a preparation method of the above solid wood fully-sealed water-based primer. The method comprises the steps of:

[0033] S01. Take each component respectively according to the described solid wood fully-sealed water-based primer;

[0034] S02. Perform mixing treatment on the weighed film-forming aid and water to obtain a first mixed material;

[0035] S03. The acrylic polymer emulsion, the thickener, the auxiliary agent, and water that have been weighed are mixed to obtain a second mixed material;

[0036] S04. The first mixed material, the second mixed material, the lignocellulose, the aqueous calcium stearate dispersion, the rheological additive, and water are mixed, and the obtained solid wood whole Sealing water-based primer.

[0037] Specifically, the solid wood fully-sealed water-based primer in the above-mentioned step S01 and the preferred content and type of each component thereof are as...

Embodiment 1

[0044] Component content and preparation method of solid wood fully-sealed water-based primer. Wherein, the weight ratio component contained in the solid wood fully sealed water-based primer component is as described in Table 1 below. The additive composition of described auxiliary agent is 0.3% wetting agent, 1% defoamer, 0.1% bactericide.

Abstract

The invention provides a kind of solid wood fully-sealed water-based primer, which comprises the following components by weight: 70%-80% acrylic polymer emulsion, 5%-80% acrylic polymer emulsion, 5%- 8% coalescent, 0.1%‑0.3% rheology additive, 1%‑3% lignocellulose, 2%‑6% aqueous calcium stearate dispersion, 1%‑3% thickener, 1‑ 3% additives, the balance is water. By adding film-forming additives and rheological additives, the thixotropy of the primer can be enhanced, and by adding lignocellulose, the filling property can be improved, the construction work can be reduced, and the construction is convenient and fast. The filling and sanding properties of the obtained solid wood fully-sealed water-based primer can achieve the effect of one-time thick coating, and at the same time, it can ensure that the thick coating will not hang, reduce the number of constructions, save time and improve efficiency during use.

Description

technical field [0001] The invention relates to polymer materials, in particular to a solid wood fully-sealed water-based thick coating primer and a preparation method thereof. Background technique [0002] At the beginning of the 20th century, major achievements in polymer scientific theory and the successful development of various polymer compounds were put into production, creating a new era for the development of paints. In the 1920s, alkyd resins specially used as film-forming substances for coatings were successfully developed. From then on, various newly developed synthetic resins were quickly applied in coatings, making coatings enter an era dominated by synthetic film-forming substances. In 1980, the annual output of coatings in the world exceeded 20 million tons, and the annual per capita consumption of coatings in developed countries reached more than 10kg. The modern coatings industry has become an important industry in the modern chemical industry. [0003] Woo...
