Abstract

The invention provides a waterborne machine sprayed stone-like paint and a preparation method thereof. The waterborne machine sprayed stone-like paint comprises the following components in percentage by mass: 10-20% of waterborne acrylic resin, 1-5% of a waterborne cosolvent, 1-5% of a polyacrylamide water solution, 0.1-2% of hydroxyethyl cellulose, 0.01-2% of a waterborne antifoamer, 60-80% of color sand, 0.1-2% of a waterborne thickening rheological agent, 0.01-2% of a pH regulator, and the balance of deionized water. The waterborne machine sprayed stone-like paint is suitable for a full-automatic paint spraying machine and a semi-automatic screw pump paint spraying machine, the machine-spraying construction atomization effect and surface texture are good, the color and plate moving speed can be adjusted according to the required coating thickness, no abnormity is found after spraying top-coat for 12 h and then soaking in water for 144 h, and a paint film has good water white resistance at the early stage. The waterborne machine sprayed stone-like paint meets the requirements for safety and environmental friendliness and energy conservation, is favorable for human health, has high spraying efficiency and low cost, and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of real stone paint, and specifically discloses a water-based machine-sprayed real stone paint and a preparation method thereof. Background technique [0002] Real stone paint, the decorative effect is similar to marble and granite, also known as liquid stone colorful paint. It is specially used for texture effect finish paint on building exterior walls. Real stone paint is very popular in the field of decorative exterior walls nowadays. Its imitation stone effect is lifelike, and its cost has obvious advantages compared with marble and granite. And the real stone paint uses natural colored sand as raw material, which has good weather resistance, high hardness and no discoloration. It has become the mainstream product of exterior wall decoration. [0003] In today's domestic real stone paint market, project site construction occupies the absolute main force of the entire real stone paint, and with the large-scale co...
