preparation example Construction

[0053] The preparation method of the above main components is as follows:

[0054] S1. Put water-based acrylic emulsion into the paint making tank, then put in pH regulator under the condition of stirring, disperse at a speed of 600-800r / min, and adjust the pH value to 8-9;

[0055] S2. Add wetting agent and defoamer in turn, and disperse for 5 minutes at a speed of 800-1000r / min;

[0056] S3. Mix the film-forming aid, slow-drying agent and deionized water evenly in advance, and slowly put them into the paint-making tank under stirring conditions;

[0057] S4. Finally, slowly put the antifungal agent and bentonite into the paint tank one by one, stir at a speed of 1000-1200r / min for 20 minutes until completely mixed, filter and pack.

Embodiment 1

[0059] Mix the main component-A with the supporting color paste according to the ratio of 100:20, and adjust to a suitable construction viscosity to obtain the substrate color wiper of Example 1.

Embodiment 2

[0061] Mix the main component-B with the matching color paste at a ratio of 100:15, and adjust to a suitable construction viscosity to obtain the base material color wiper of Example 2.

Abstract

The invention provides a base material coloring agent, which comprises a main component and a matched color paste. The main component and the matched color paste are mixed according to a proportion of100:(5-30); the main component is composed of the following components by weight percentage: 10-50% of a water-based acrylic emulsion, 0.2-0.5% of a pH regulator, 0.3-0.5% of a wetting agent, 0.2-0.5% of a defoaming agent, 2-5% of a film-forming assistant, 5-40% of a slow drying agent, 5-20% of deionized water, 0.1-0.3% of a mildew preventive and 0.3-0.5$ of bentonite. According to the base material coloring agent, the multi-layer core-shell structure water-based acrylic emulsion is used as the main body resin, and is matched with other auxiliary agents, so that a paint film has excellent wiping property and coloring property, and good packaging effect and color naturalness can be achieved by applying the coloring agent without spraying a water-based seal primer. The invention further provides a preparation method of the base material coloring agent.

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to a water-based base material color eraser and a preparation method thereof. Background technique [0002] With the implementation of environmental protection policies in various places, people are becoming more and more aware of green and environmentally friendly coatings, and water-based household coatings have become a product application trend. [0003] The color wiper is mainly used for the coating product of substrate coloring. In the existing market, when the products of water-based water-based surface and UV-based water-based surface are used for transparent and colored processes, they are often wiped by Grace. The operating process is water-based closed bottom-water-based transparent bottom-water-based topcoat; UV process: water-based bottom-UV bottom-UV bottom-UV topcoat (water-based topcoat). Among the above processes: the water-based process generally has the ...
