Widely applied really stone paint what hidden secret?

Today, really stone paint has become more and more popular. Urban construction and the outer walls of the cottage, true stone lacquer is essentially choose architecture. In recent years, really stone paint won the favour of people. Why true stone lacquer is so popular and loved? Next, small KeBao building materials series will uncover the secret of true stone paint. Advantages: 1, adornment sex is strong, with natural stone, marble and granite of thick slurry coating. Natural color, has the natural stone texture, a variety of line design, can provide a variety of solid structure, can directly show the elegant solemn beauty of the building, is the best alternative of dry hanging stone wall. Advantage 2: widely used can be used in the cement brick wall, foam, gypsum, aluminum plate, glass and other base, according to the architectural shape any paint. Advantage 3: water-based environmental protection really stone paint USES water-based emulsion, avirulent environmental protection, accord with the requirement of people for environmental protection. Advantages 4: good resistance to 90% of the dirt to dirt adhesion. By rain washed after it as bright as new, more easy to wash by hand. Advantage 5: long service life and high quality really stone paint sustainable for 15 years. Advantage 6: economical really stone paint quality is good, the market price of every square metre is about 70 - 150 yuan, Including buildings) , dry hanging stone installation costs at least 400 yuan/square meters. True stone lacquer is, by contrast, the cost effectiveness of absolute advantage. Advantage 7: no potential safety hazard dry hanging stone wall will increase the extra burden of thousands of tons, seriously endanger the lives and property. Use 4 - really stone paint 5 ㎡ / ㎡, only 1/30 of the stone weight. Strong adhesion, don't fall off like a stone, effectively guarantee the safety. Fixed after coating is very hard, really stone paint dry nails are not scrape. If ordinary really stone paint in construction after three days of good weather conditions can still be a nail scratch, coating should be considered too soft, mainly because of the choice of the emulsion is not appropriate. When preparation really stone paint, construction personnel using the same emulsion and latex paint, really stone paint formulation emulsion levels were lower, film-forming exists when a large number of sand and gravel, coating is not quite close together. Researchers according to coating, really stone paint used in the preparation of emulsion adhesive strength should not be less than 3 mpa, the minimum film-forming temperature should not be below 15 ℃. Higher minimum film-forming temperature may cause when the air temperature is low is not easy to film defects, this can be achieved by adding more appropriately film additive to solve. Film forming additive in completely volatilize after coating is dry, generally does not affect the performance of the coating. True stone lacquer is a kind of high adhesion and high minimum film-forming temperature of composite emulsion, fundamentally solve the problem of the coating is too soft. Every time after the rain, some real change white stone paint coating will become loose. However, after the rain stopped, the coating after exposure to the sun will return to its original color. In fact, this is due to the poor resistance to water and water imbibition of coating. The formula is based on the fact that the choice of acrylic emulsion need to add the surfactant in the synthesis process. Some manufacturers use a lot of surface active agent to increase the stability of the emulsion. Some manufacturers to join in the preparation of really stone paint materials such as carboxymethyl cellulose, hydroxyethyl cellulose as a thickening agent, sodium benzoate as a preservative. These substances is a water soluble or hydrophilicity, and when stay in the coating after coating in the film, the water resistance of coating is reduced greatly. Experiments show that the coating of pure acrylic emulsion and quartz sand coating formed by bibulous rate is 0. 42? 0. 4? Ethyl cellulose, bibulous rate is up to 4. 3? Because really stone paint coating is relatively thick, suction, once it is not easily released in a short period of time, resulting in loose white appearance and internal coating. Really stone paint ESE film-forming additive is silicone modified acrylate emulsion ( Silicone acrylic emulsion) 。 After drying, good water resistance
