Coating classification: waterborne nano color paste

Core tip: product brief introduction: water-based nano color paste is a kind of special effect of nano particles, such as quantum size effect, surface effect, macro quantum tunneling effect, dielectric confinement effect, etc., which is achieved by nano particles of common pigments or by proper combination of nano materials and common pigments through advanced technology, precise equipment and reasonable control Nano ultra-fine grinding technology used in the preparation of water-based color paste can make the particle size of pigment dispersion smaller and the particle size distribution narrower, and can improve the color strength, color light, UV resistance (weather resistance), transparency (freshness) of color paste Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Coating House News: Product Introduction: water-based nano color paste is to nanometer common pigment particles through advanced technology, precise equipment and reasonable control, or to achieve water-based and sizing through proper combination of nano materials and common pigments, It has the special effects of quantum size effect, surface effect, macroscopic quantum tunneling effect, dielectric confinement effect and so on Nano ultra-fine grinding technology used in the preparation of water-based color paste can make the particle size of pigment dispersion smaller and the particle size distribution narrower It can improve the color strength, color light, UV resistance (weather resistance), transparency (freshness), antibacterial and mildew resistance and state stability of color paste Some color pastes also have dispersion that ordinary pigments can't match For example, the superfine (nano) of iron oxide red eliminates the flocculation caused by magnetic attraction, so it is easy to disperse and has excellent anti flocculation property Function: due to different particle size of the same nano material, the material performance will be greatly different, and different nano materials also play different functions in the modification of coating Main varieties: aging resistance of nano TiO 2 is an important index of coating Generally, the coating film will be aged, yellow, brittle or even peeled in a short period of time, which is mainly caused by the chemical bond degradation fracture of polymer, including thermal degradation, oxidation degradation, hydrolysis and biodegradation The aging of coating film used at room temperature is mainly caused by photo oxidation degradation Nano-TiO2 has strong UV absorption and scattering properties Therefore, adding nano-TiO2 to the coating formulation can effectively improve the UV (aging) resistance of the coating Under the irradiation of ultraviolet light, nano-TiO2 particles can decompose free moving negative electrons (E -) and positive holes (H +), forming electron hole pairs, which can interact with oxygen and H2O in the air, and form atomic oxygen (o) and hydroxyl radicals (HO) through a series of chemical reactions ）This kind of atomic oxygen and hydroxyl radicals have high chemical activity, can react with the organic compounds in bacteria, and generate carbon dioxide and water, so as to kill bacteria Therefore, adding nano-t-io2 to the coating can also give the coating bactericidal, antifouling, deodorizing and self-cleaning functions, which are generally used for the interior wall surface of families and hospitals, and can also completely remove the harmful organic poisons in the air and water to play a cleaning role Nano silicon dioxide (SiO2) nano silicon dioxide is an amorphous white powder There are unsaturated residual bonds and hydroxyl groups in different bonding states on its surface Its molecular state is a three-dimensional chain structure, which can give the coating excellent thixotropy and dispersion stability At the same time, nano-SiO2 has a strong UV reflection ability, which can form a shielding effect in the coating, achieve the purpose of anti UV aging, and increase the thermal insulation of the coating Therefore, nano-SiO2 is a good coating additive Adding nanoscale silicon dioxide into the coating can obviously improve the opening effect of the coating The coating is not easy to be layered, has thixotropic property, prevents flow hanging, has good construction performance, and improves the aging resistance, thermal stability and intensity The free moving electrons (E -) and positively charged holes (H -) can be dissociated by nano ZnO in water and air under sunlight, especially under ultraviolet irradiation+ ）This kind of hole can activate the oxygen in the air to become the active oxygen The active oxygen has a strong chemical activity and can react with a variety of organic matters (including the organic matters in the bacteria), so as to eliminate a large number of bacteria and viruses Therefore, when nano ZnO and other nano materials are used in the coating, the coating has the functions of shielding ultraviolet, absorbing infrared light, anti bacteria and anti mildew, which can not only purify the air, but also anti bacteria and deodorization At the same time, nano ZnO has strong ultraviolet absorption capability and can be used as anti-aging additive for coatings Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
