What is real stone paint?
Real stone paint is a kind of architectural paint with decorative effect similar to marble and granite.
How many parts does real stone paint consist of?
• Alkali resistant sealing primer: divided into oil-based and water-based two. Oil-based sealing primer is mainly composed of acrylic resin or silicone acrylic resin and solvent dilution; Water-based sealing primer is composed of special styrene acrylic emulsion and pure acrylic emulsion with water, additives, etc., which is divided into anionic emulsion sealing primer and cationic emulsion sealing primer, cationic emulsion sealing primer has the best performance. The function of the sealing primer is that after the evaporation of water or solvent, the emulsion or resin penetrates into the substrate gap and pores, enhances the waterproof performance of the surface of the substrate, prevents the substrate from caustic and flowers due to water migration, and enhances the adhesion between the main layer and the base layer of the real stone paint.
• Intermediate layer: composed of binder, aggregate, auxiliary and water.
• Binder: The most commonly used binder for real stone paint is synthetic resin emulsion or synthetic resin emulsion and silica sol composite class, there are many different properties of emulsion to choose from.
• Aggregate: mainly using natural colored sand, such as white marble, marble, granite and other stone, can also use quartz, dolomite, can also use artificial colored sand or natural colored sand and artificial colored sand mixed. Natural color sand is processed by crushing, cleaning, screening and other processes, with natural stone good weather resistance, acid and alkali resistance, hardness and natural color and luster. The particle grade of aggregate has a great impact on the state and constructability of real stone paint, and the grain size range of natural color sand is generally 10-120 mesh.
• Additives: mainly thickening agent, film forming agent, defoamer, dispersant, preservative, anti-mold agent, adhesion enhancer, waterproofing agent, penetrant and so on. Thickeners are used to increase the viscosity of real stone paint, meet the viscosity required for injection during construction, and improve its storage stability, commonly used thickeners are hydroxyethyl cellulose, polyacrylates, polyurethane association thickeners and other three categories, each can be used alone, can also be used together.
• Cover layer: It is a protective layer of finish, which can strengthen the waterproof function of the real stone paint layer, and improve the weatherability and pollution resistance of the coating, so that the surface of the coating is bright and transparent, and it is easy to clean later.
Real stone paint has the following characteristics and advantages:
• Decorative: can show the texture and texture of natural stone, such as marble, granite and other effects, colors and styles are diverse, giving people a vivid and vivid visual feeling of returning to nature, so that the building has a natural, solemn, atmospheric appearance, can enhance the aesthetics of the building and artistic value.
• Wide application: can be used for cement brick wall, foam, gypsum, aluminum plate, glass and other bases, can be arbitrarily painted with the shape of the building, and has a good adaptability to complex curved surfaces, whether indoor and outdoor decoration or arts and crafts, urban sculpture can be applied.
• Environmental protection: The use of water-based emulsion, non-toxic environmental protection, in the production, construction, use will not produce harmful substances (especially volatile benzene chemicals that cause great harm to human health).
• Good pollution resistance: large surface tension, with obvious water repellency, not easy to vacuum, not easy to pollute, 90% of the dirt is difficult to adhere, bright as new after rain wash, artificial cleaning is easier.
• Long service life: The service life of high-quality real stone paint can be up to 15 years, with good weather resistance, color preservation, anti-mildew and anti-dryness, no aging and other characteristics, can resist the erosion of natural factors such as ultraviolet light, acid rain, wind and sand, effectively extend the service life of buildings, especially suitable for use in cold areas.
• Anti-crack and anti-seepage: It has a slight extension, can effectively cover fine cracks, toughness, strong adhesion, can overcome the small cracks in the wall mortar, and play an impermeable and waterproof role in the external wall.
• No color change, high hardness: Select high-quality natural sand, long-term use of no yellow, no white, because the natural color sand from natural stone, with high-performance emulsion, the coating thickness of the finished stone paint is 2-4mm, with the hardness equivalent to marble, the wall protection effect is very significant.
• Convenient construction: Usually using spraying and other construction methods, construction speed is fast, high efficiency, can save labor costs to a certain extent.
• Affordable: Compared with other exterior wall decoration materials such as dry hanging stone, the price of real stone paint is relatively low, the overall cost is low, and it has a high cost performance.
• High safety: the external wall using stone dry hanging will load thousands of tons of additional burden, seriously endangering life and property, and the real stone paint material only accounts for 1/30 of the weight of the stone, the adhesion is strong, will not fall off like the stone as a whole, can effectively ensure safety.
The company produces water-based latex paint, which is the main component of real stone paint, emulsion is a paint containing acrylic polymers dispersed in water. It is commonly used as an adhesive in the manufacture of real stone paint. Real stone paint is an exterior wall paint designed to mimic the appearance of natural stone and is suitable for the following surfaces: concrete, stucco or brick
Properties:
Styrene-acrylic emulsion, good scrub resistance and water resistance.
Applications:
Raw material for building interior wall coating/building coating/Styrene-acrylic aqueous polymer emulsion for exterior and interior latex paint.
