Really stone paint technology status quo

Really stone paint in construction market vigorous development in recent years. Its advantages are simple technology, low cost, market demand is big. However, in the long run, really stone paint industry will become more and more fierce competition. Future development must depend on technological upgrading, out of the differentiation of product development, looking for the high-end market space. By mainstream really stone paint in the market, the analysis of the practical application, some deficiencies still exist really stone paint, mainly manifested in the following aspects, need to improve the item by item on product technology and perfect. 1. Really stone paint latex is mainly type high glass transition temperature. Although can guarantee a certain hardness of paint film, but also lack of paint film toughness of potential danger, especially the film at low temperature easily embrittlement after long-term use, prone to frost heave after repeated stress cracking. 2. Really stone paint coating thickness of general control in 15 mm to 2. 0 mm, between relatively thick. Although the film have certain water proofing property and air permeability, after but the color sand particle surface is emulsion coating is relatively dense, directly affect the permeability of coating is poor. If the emulsion dosage reduction, coating adhesion decreases, the coating quality cannot be guaranteed. 3. Really stone paint with natural color sand due to the different composition and purity, mostly with acid and reactive, this greatly limits the acid alkali and salt fog corrosion resistance coating, which affects the use of paint film durability. 4. Really stone paint with different number of mesh graded sand and stone powder system. Coating coverage is mainly the suitability is determined by the packing density of the sand. As a feature of the shape of sand coating, the coating after nature presents obvious gap problem, so the color paint film defects caused by the phenomenon such as off color, yellow, white will directly affect the effect of covering film. 5. Really stone paint with film-forming substances are mostly acrylic modified acrylic polymer emulsion or film-forming temperature is higher. As a result of thick coating process, coating drying time is longer, and much affected by temperature. If the environment temperature is too low, paint film is subject to the influence of uneven luster and fog shadow white.
