Embodiment 1-3

[0054] According to the prescription of table 2-1 (embodiment 1), 2-2 (embodiment 2), 2-3 (embodiment 3) respectively, each component in the table is mixed and prepared to obtain three kinds of paint surface treatment compositions of the present invention . The specific preparation method is: under the condition of low-speed (400-800 rpm) disperser stirring, according to the formula sequence and proportion of each sample in Table 2, the raw materials are sequentially added to the container, first half of the rheological agent is added, and the high-speed (3000-5000 rpm / min) disperse and stir for 10-15 minutes. Then add a rheological agent to adjust the viscosity (12000-20000 centipoise) under the condition of stirring at a medium speed (1200-1400 rpm) to obtain a stable grinding paste system with a pH of 8.2-8.4.

Abstract

The invention provides a lacquer painting processing composition comprising a dispersion medium and a grinding aid dispersed in the dispersion medium. The average grain diameter of the grinding aid is 12-55 microns, and the Mohs hardness of the grinding aid is 5.5-6. The invention also provides a lacquer painting processing method and a lacquer painting mending method adopting the lacquer painting processing composition.

Description

Technical field: [0001] The invention relates to a paint surface treatment composition, a paint surface treatment method and a paint surface repair method, in particular to a low-gloss paint surface treatment composition, especially a low-gloss paint surface abrasive paste, and the paint surface treatment method The method for treating the paint surface of the composition and the method for repairing the paint surface. Background technique [0002] A matt surface is an important application performance in the coatings and varnish industry. Matting effects can be found everywhere in everyday life: at home, on the way to work, or in a restaurant at night. Most of the indoor furniture adopts a matte surface, and the wooden panels covering the exterior of the restaurant basically also have a matte appearance. When faced with the choice of glossy or matte effects, we are not limited to fashion and appearance needs. Practice has proved that the requirements for easy cleaning, g...
