GN-90-nm in aqueous solution of inorganic silica coating application properties 

 1, the energy saving: nano-particles with large particles do not have special optical properties, the prevalence of the "blue shift" phenomenon. The spectrophotometer tests showed, GN-9O Inorganic silica particles with a strong UV absorption, infrared reflection characteristics of the wavelength of 400nm or less of the UV absorption rate of 70% or more, for less than 400nm wavelength infrared light reflectivity of more than 70%. Add it at the water-based paints, can coatings form a shielding effect, to UV aging and thermal aging purposes, while increasing the insulation coating. So there are energy saving effect. 

 2, resistant to washing: Add GN-90-nm silicon solutions of inorganic water-based paint washability substantial increase, especially in areas used for interior and exterior latex paints, scrub resistance from one thousand to about 5-7 thousand or so. 

 3, the weather: weather can be increased by 3 times, adding a certain amount of GM-9O Inorganic silicon allows the traditional water-based paint products, ultraviolet aging properties from the original 250h (powder 1, color 2) to 600 h (no powder, no color film, color value of 4.8) or more. Vehicles and vessels used in water-based paint, add the GN-90 inorganic silicon solution is to improve the coating finish and the key anti-aging properties, the coating is dry, GN-90-nm silicon-inorganic network structure can be formed quickly, so aging resistance, smoothness and strength improved several times, weather-resistant up to 10 years. 

 4, stain resistance and self-cleaning: Studies have shown that, through the following ways can improve the coating of stain resistance and self-cleaning, one use of GN-90-nm silica particles of inorganic microporous structure, through a certain surface coating process means in the context of nano-scale geometry of complementary (such as convex and concave white) interface structure, adsorption to the surface layer of air stable in the gas barrier film; Second is the GN-90-nm inorganic silicon particle surface treatment to the surface showing parents or dual-sparse, thus effectively improving the water on the surface of the wetting film architectural coatings and dust adhesion, stain-resistant coating to improve and self-cleaning ability. 

 5, antibacterial: in water-based coatings, when the GN-90-nm inorganic silicon solution to add more than 3%, the coating showed significant antibacterial effect. 

 6, the hydrophobic acid alkaline corrosion: add GN-90 aqueous solution Inorganic hydrophobic silicon anti-corrosion coating, not only has good adhesion, corrosion resistance, anti-acid, but also has high resistance and ion density permeability. 

 7, Transparency: GN-90-nm silicon solutions of inorganic nano-modified water-based paint can to ensure transparency. The use of GN-90 Inorganic silicon solution can be obtained highly wear-resistant transparent water-based coatings to improve wear resistance 10 times more than the original. 

 8, hardness and flexibility: When the GN-90-nm silica particles of inorganic materials in organic individual particles were uniformly dispersed and nano-particles as rigid as the chain from the enhanced role of the organic material to improve the film hardness of UV-curable coatings up to 2.5 times, and after the coating film has some flexibility. 

 9, thermal stability: the water-based UV-curable coatings, GN-90-nm inorganic silicon solution can improve the coating of the glass transition temperature. 

 10, temperature: the product has a high temperature performance, high temperature of 1100 degrees. 

 11, the film of any such modification with the organic compound, monomer film, joined GN-90-nm silicon solutions of inorganic water-based paint is more superior film quality. 

 Add water-based coating materials of inorganic silicon nano-GN-90 solution after solution, there is the suspension stability is poor, poor thixotropy, finish, not high also be a good solution; add GN-90-nm silicon solutions of inorganic water-based paint cans effect of also significantly improved, coating non-hierarchical, anti-sagging, the construction of a good, strong adhesion. 

 Three using methods 

 GN-90 nm dispersed inorganic silicon solution can use a variety of methods, such as milling, high shear, milling, sanding, ultrasonic dispersion, etc., of which the first two methods use more. The GN-90-nm inorganic silicon solution to the water-based paint, the dispersion step is divided into one-step and two-step method. 

 Step refers to the KH-modified nano-silica solution was added to the product of inorganic materials systems directly to obtain the required content of certain products in the paint grinding stage to join with other fillers, or added to the water-based paste in the first to participate in high-speed dispersion, and then mixed with the emulsion. Step is characterized by the production process is simple, more suitable for high-volume, single-product production. 

 Two-step method is the first GN-90 Inorganic silicon solution to the ratio of scattered to higher raw material master batch, and then diluted by adding material to a certain proportion. As the two-step method is characterized by high viscosity, shear force when dispersing large, GN-90-nm well dispersed inorganic silicon solution for multi-variety production. At present, domestic enterprises to use good quality products distributed mainly taken the step of the way high-speed shear dispersion, can basically meet the needs of users. 

 Fourth, applications, add the amount (%), product characteristics and performance 

 1 water-based sealer because the GN-90-nm silicon solution has a strong inorganic adsorption capacity and acid corrosion resistance, the production capacity of up to 30% of the added primer, an excellent sealing effect, excellent adhesion, reduce costs significantly improve the quality effect is remarkable. 

 2, water-based interior and exterior latex paint: Add 3 to 13, can play a good thixotropy, anti-settlement, anti-sagging, increase strength, increase wear resistance, enhanced weather resistance, water resistance and so on. 

 In the production of water-based putty, water-based sealers, water-based interior and exterior latex paint, because of GN-90 silicon solution and the production of inorganic nano-emulsion paint mixed with a nano-emulsions, nano-emulsion as the main film-forming substances, can effectively penetrate the wall of micro- hole in the wall surface of a dense film of high alkali resistance, good closed, closed for the needs of alkali and the role of residential, office, hotel and other old and new walls. Use this water-based products and water-based sealer paste putty, can form an effective alkali, can effectively prevent the precipitation of water-soluble salts are alkali, alkaline salts to protect the finish against corrosion, has excellent adhesion and good mildew, a balanced absorbent substrate can maximize paint color and opacity. 

 3, water-based metallic paint: Add the amount of 5-12, corrosion, rust, good coverage, hardness, increased adhesion. 

 4, water-based paint relief: the amount of 6 added to increase the adhesion, good coverage, increase wear resistance, enhanced durability. 

 5, water-based lacquer: Add the amount of 6-7, to increase adhesion, good coverage, enhanced weather resistance, increased hardness and toughness. 

 6, water-based glass paint: Add the amount of 5-10, increased adhesion, enhanced weather resistance. 

 7, heritage paint: Add the amount of 6-12, to increase adhesion, increased wear resistance, good coverage, enhanced durability 

 8, water-based Wood: Add the amount of 5-20, increased wear resistance, enhanced weather resistance, increased hardness and adhesion. 

 9, water-based paste: Add the amount of 5, anti-settlement. 

 10, water-based ink: Add the amount of 5, thickening, thixotropic, anti-settlement, to increase adhesion and improve the brightness and contrast. 

 In short, adding GN-90-nm inorganic silicon solution produced a change in water-based paint water-based paint on traditional prejudices, to first-class quality, a significant effect, energy saving is getting people approved the production of water-based paint manufacturers to improve product quality, production cost reduction, economic efficiency significantly, greatly enhanced the competitiveness of enterprises.
