Abstract

The invention relates to a yellowing-resistant real stone paint, which is made of the following raw materials in the weight ratio: 5.0-12.0 parts of water, 0.14-0.18 parts of hydroxyethyl cellulose, 0.05-0.1 parts of water-based multifunctional additives, and a dispersant 0.08-0.15 parts, 0.04-0.08 parts of wetting agent, 0.4-0.6 parts of water-based titanium dioxide paste, 11.0-18.0 parts of water-resistant white emulsion, 0.5-0.8 parts of coalescent agent, 0.3-0.5 parts of co-solvent, and 0.05 parts of defoamer ‑0.12 parts, rheological additives 0.04‑0.06 parts, preservatives 0.1‑0.15 parts, aggregate 73.0‑76.0 parts. This invention overcomes the shortcomings of the existing light-colored real stone paint, such as staining, yellowing, and decomposition, which are easily damaged by ultraviolet radiation due to the non-dense paint film and the binder used. The advantages of stain resistance, yellowing resistance, and not easy to decompose.

Description

technical field [0001] The invention relates to a yellowing-resistant real stone paint and a preparation method thereof. Background technique [0002] As a new type of environmentally friendly building material, real stone paint has occupied an important position in the field of exterior wall engineering coating, gradually replacing traditional decorative materials such as ordinary stone, and it will continue to maintain this advantage in the future, with broad market prospects. [0003] Existing white and other light-color real stone paints are prone to color deepening problems such as yellowing as the use time increases. The reasons are as follows: 1. Because the microstructure of the real stone paint is uneven and the paint film is not dense, solid particles such as dust are easy to accumulate on the surface, which is easy to cause contamination and yellowing. 2. The acrylic emulsion used as a binder in the base material, especially the styrene-acrylic emulsion, after ul...
