Coating knowledge: in order to adapt to social development, new environmental protection coatings are launched

Core tip: when people choose houses now, they have passed the era with the main purpose of solving the problem of food and clothing, and began to pay more attention to the beauty and other properties, such as the South tends to heat insulation exterior wall coating, the North pays more attention to weather resistance and so on However, no matter the South and the north, the whole world tends to one direction - green environmental protection This is also to better meet the needs of consumption and social development Several common new exterior wall coatings are introduced as follows: 1 Nano coating: nano Ti02 has attracted more and more attention due to its unique photocatalytic performance, UV shielding and angular heterochromism since it was invented in 1980s 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 Paint House News: when people choose houses now, they have passed the era with the main purpose of solving the problem of food and clothing, and began to pay more attention to the beauty and other properties, such as the south is inclined to heat insulation exterior wall paint, the north is more inclined to weather resistance, etc., however, the whole world in the north and the south is inclined to one direction - green environmental protection This is also to better meet the needs of consumption and social development Several common new exterior wall coatings are introduced as follows: 1 Nano coating: nano Ti02 has attracted more and more attention due to its unique photocatalytic performance, UV shielding and angular heterochromism effect since its appearance in 1980s At present, as a new functional material, nano-TiO2 provides a good condition for the development of green coatings; nano-TiO2 modified building coatings have high washability, antibacterial, self-cleaning and aging resistance Adding nano-TiO2 into epoxy resin coating as UV absorber can prevent the chain from cracking due to long-term UV irradiation, so as to make up for its poor weather resistance and significantly improve its aging resistance 2 Energy storage and luminous paint: energy storage and luminous paint for exterior wall belongs to special functional paint, which can fully show the appearance of the whole building at night, with good decorative effect; If this kind of coating can be successfully industrialized and applied in all commercial areas of the city, the quantity of floodlighting can be greatly reduced while enhancing the night scene decoration of the city, which not only saves the initial investment of the building, but also saves considerable power The afterglow of building exterior wall water-based energy storage luminous coating increases with the increase of illuminance, which is related to the length of illumination time Generally, it takes more than 20 minutes to reach saturation state, and it reaches saturation within 10 minutes when the light is very strong After dark, its afterglow is higher within 4 hours, and the effect is obvious Then with the extension of time, the afterglow time of the luminescent coating can reach 14h In addition, the result of radioactivity test of the coating belongs to class A, which proves that the luminous coating can be used in various environments 3, powdery architectural coatings: Architectural Coatings powder has many unique technical, economic and environmental advantages, especially for synthetic resin emulsion coatings, auxiliaries in the cost of a large proportion of the formula, many of these auxiliaries are used to maintain the storage performance of the paint, after the powder can eliminate the use of such auxiliaries, but also can save considerable packaging costs Not only that, because after the coating is powdered, the Portland cement, gypsum and lime with low price and many unique performance advantages can be easily used in its components, without high-temperature baking, so that the powder building coating has a good performance cost comprehensive advantage, and has a good development prospect 4 Elastic exterior wall coating: most of the exterior walls of buildings are leveled with cement mortar before surface coating Due to the inherent characteristics of cement-based materials, when affected by environmental factors such as temperature change, dry wet alternation, freeze-thaw cycle, cracks often occur If the surface is painted with paint, it will lead to cracks In view of this kind of malpractice of building exterior wall, a kind of elastic exterior wall coating has been developed recently Elastic exterior wall coating is a kind of functional architectural coating, which not only has a good decorative effect on the exterior wall, but also has a special function of covering the cracks in the base layer [focus on WeChat official account "paint net";
