Paint knowledge advantages and attention of real stone paint

Core tips: the production process of real stone paint is simple, low cost, excellent performance, and it has broad prospects for development to higher grade, such as environmental protection, high elasticity, non stick dust series It is suitable for concrete or cement inside and outside walls and brick walls, as well as asbestos cement boards, boards, gypsum boards, polyurethane foam boards and other base materials The base course on the surface of construction base material shall be flat, clean and of good strength The new wall shall be dry for one month before construction The old wall shall be renovated The base course shall be leveled first, and the impurities such as loose, peeling surface and dust and oil dirt shall be removed before construction In order to meet the needs of the increasingly personalized development of high-grade building decoration industry, such as imitation marble, imitation granite coating Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings news: the production process of real stone paint is simple, low cost, excellent performance, and it has broad prospects for higher-grade development, such as environmental protection, high elasticity, non stick dust series It is suitable for concrete or cement inside and outside walls and brick walls, as well as asbestos cement boards, boards,

construction In order to meet the needs of the increasingly personalized development of high-grade building decoration industry, such as the development of imitation marble and granite paint, the importance of spraying technology is more shown Only a more complete and matching construction technology can fully show the unique appearance and excellent performance of real stone paint The high-grade real stone paint must be matched with strict construction technology Although the quality of the paint is good, if the construction personnel are inexperienced and of low quality, and do not understand or understand the performance of different real stone paint, it will also cause various problems The hardness of the coating is very hard after the construction of the stone paint The nail can not be scratching The ordinary genuine lacquer can still be drawn with nails when it is in good weather for three days It should be considered that the coating is too soft The main reason is that the emulsion is not suitable When preparing genuine stone lacquer, they use the same emulsion as the latex paint, which results in the low emulsion content in the formula of the real stone paint, and the coating is not tight enough because of the existence of a large amount of sand and gravel during the film formation Research by paint researchers: the bonding strength of the emulsion used for genuine stone paint should not be lower than 3MPa, and the minimum film forming temperature should not be below 15 C A higher minimum film forming temperature may cause the disadvantage that it is not easy to form film at a lower temperature, which can be solved by adding more film forming AIDS appropriately The film-forming agent can volatilize completely after the coating is dried, which will not affect the performance of the coating generally The choice of genuine stone paint is the composite emulsion with high cohesive force and the lowest film forming temperature, which fundamentally solves the problem of too soft coating The coating has good water resistance, stable coloring coating has good water resistance, stable coloring, no whitening, no color difference Some real stone paint coating will turn white after every rain, and the coating will become loose After the rain stops, the coating will return to its original color after a sun exposure In fact, this is due to the poor water resistance of the coating and the absorption of moisture The formula is that the acrylic emulsion used in the synthesis needs surfactant when it is synthesized Some manufacturers add carboxymethylcellulose, hydroxyethyl cellulose and other substances as thickeners and sodium benzoate as preservatives in the preparation of real stone paint These substances are water-soluble or hydrophilic If the coating remains in the coating after film formation, the water resistance of the coating will be greatly reduced Experiments showed that the pure acrylic emulsion mixed with quartz sand without any auxiliaries, the water absorption rate of the sprayed coating was 0.42%, and the water absorption rate increased to 4.3% on the basis of the above coating by adding 0.4% hydroxyethyl cellulose Due to the thick coating of real stone paint, once the moisture is absorbed, it is not easy to release in a short time, resulting in the appearance of white, loose coating The film builder used in genuine stone lacquer ESE: silicone modified acrylate emulsion (silicone acrylic emulsion) It has good water resistance after drying, so the coating will not turn white when it meets water after drying With the improvement of decorative requirements for interior and exterior wall coatings, natural stone paint is more and more popular with people for its unique appearance and performance Many high-end residential buildings, courtyards and even high-rise buildings have put forward the real stone paint which is very close to the natural stone appearance such as natural granite and marble In terms of performance, it is required to have strong hardness, waterproof, aging resistance, etc According to our experience, we will briefly introduce some experience in the preparation and spraying process of natural stone paint Paint, ink, resin, adhesive, formula I, natural stone paint natural stone paint is mainly made of high polymer, natural color stone sand and related additives After dry curing, it is hard as stone, with the effect of imitating natural stone, strong adhesion, weather resistance, water resistance, and easy to repair The supporting construction includes alkali resistant sealing base oil, weather resistant waterproof surface oil Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and
