Waterborne ultralow-VOC-content high-weatherability real stone paint and preparation method thereof

Abstract

The invention discloses a waterborne ultralow-VOC-content high-weatherability real stone paint and a preparation method thereof. The waterborne ultralow-VOC-content high-weatherability real stone paint is prepared from the following raw materials by weight: 9 to 11 parts of pure acrylic emulsion, 4 to 6 parts of silica sol, 0.2 to 0.3 part of a compatibility stabilizing agent, 9 to 11 parts of deionized water, 0.2 to 0.25 part of cellulose, 0. 1 to 0.3 part of an antifoaming agent, 0.1 to 0.2 part of an antiseptic, 1 to 1.5 parts of an antifreezing agent, 0.6 to 0.8 part of a film forming aid, 65 to 75 parts of sintering colored sand, 0.5 to 1.0 part of aluminum-magnesium silicate and 0.1 to 0.5 part of a thickening agent. The real stone paint provided by the invention has the characteristics of healthiness, environmental protection, excellent water resistance, stain resistance and weatherability, excellent slipperiness in construction, simplicity, etc.

Description

technical field [0001] The invention relates to the technical field of coatings, and more specifically relates to a water-based ultra-low VOC high-weather-resistant real stone paint and a preparation method thereof. Background technique [0002] Real stone paint is a kind of decorative effect similar to marble and granite. It is mainly made of natural stone powder of various colors. The buildings decorated with real stone paint have natural and real natural color, which gives people a sense of elegance, harmony and solemnity. It is suitable for indoor and outdoor decoration of all kinds of buildings. Especially when it is decorated on curved buildings, it is vivid and lifelike, and has an effect of returning to nature. Real stone paint has fire protection, waterproof, acid and alkali resistance, and pollution resistance. Non-toxic, tasteless, strong adhesion, never fade and other characteristics, can effectively prevent the external harsh environment from eroding the buil...

Problems solved by technology

Real stone paint has the advantages of simple construction, easy drying, time saving, and convenient construction. However, the performance of real stone paint on the market is generally poor in actual applications, which affects the appearance and service life of the coating. The production technology is scarce, so it is optional. very low

[0003] Chinese patent CN103409024A discloses a regenerated genuine stone paint, in which regenerated sand is added to the raw material, so that the real stone paint can consume a large amount of regenerated sand, but the regenerated sand is processed in the foundry production and basically restores the usability and can be reused The used sand has strict requirements on processing methods and unstable quality

[0004] Chinese patent CN104804565A discloses a pottery sand real stone paint and its preparation method. Pottery sand and quartz sand are added to the raw materials to make the real stone paint have a certain thermal insulation performance, but the pottery sand is porous inside and the compressive strength is low. Easily damaged during production, affecting product performance
