Titanium dioxide in the rubber industry, both as a coloring agent, but also has reinforced, anti-aging, filling effect. Join in white and colored rubber products titanium dioxide, in the sunlight, sun-resistant, no crack, no discoloration, large elongation and acid. Rubber with titanium dioxide, is mainly used for automobile tires and rubber shoes, rubber flooring, gloves, sports equipment, etc., generally the main anatase. However, for the production of automobile tires, often adding a certain amount of rutile products to enhance the anti-ozone and UV resistance. Titanium dioxide in cosmetics applications are becoming increasingly widespread. Due to non-toxic titanium dioxide, than the lead white is superior, almost all kinds of powder are used in place of titanium dioxide, white lead and zinc white. Powder in only 5% -8% of titanium dioxide can be obtained permanent white, make spice more creamy with adhesion, absorption and opacity. In gouache and cream in a transparent titanium dioxide can be reduced and the feeling greasy. Various other spices, sunscreen, soap flakes, white soap and toothpaste are also available titanium dioxide. Enamel transparency obtained with titanium dioxide, and has a small mass, impact resistance, good mechanical properties, colorful, easy to pollution. Food and medical use titanium dioxide as high purity, low heavy metal content, strong hiding power of titanium dioxide. GR composite titanium dioxide pigment titanium dioxide --- ---- --- replace titanium dioxide using titanium white pigment titanium dioxide --- ---- ---- composite titanium white pigment titanium dioxide GR composite titanium dioxide pigments are selected and particle size distribution profile of a structure similar to titanium dioxide and the like, and the surface reactive inorganic powder as the basic raw material (core), TiO2 was coated material, the application of new composite material modification preparation, inorganic coating, powder homogenization and other high-tech, prepared from refined segmentation by both surface hydroxylation transformation and mechano-chemical reactions, etc. new composite white pigment, titanium dioxide, which has the same or similar physical and chemical properties, which has a titanium dioxide pigment properties. Widely used in paints, plastics, rubber, ink industry, titanium dioxide can be obtained with the use of the same technical performance, and less dramatically reduce the cost of raw materials. Production and application of GR composite titanium dioxide pigment, is to solve the shortage of resources in the production of titanium dioxide, reduce environmental pollution, improve resource utilization titanium dioxide effective way. Preparation and application of technology products by the Beijing Municipal Science and Technology Organization experts, has been assessed to reach the international advanced level, the products have been assessed as high-tech products in Anhui Province. GR composite titanium dioxide pigment performance characteristics 

1, GR composite titanium dioxide pigment preparation technology reached the international advanced level, including the choice of nuclear material, nuclear material and capsular bag surface hydroxylation and composite white pigment titanium dioxide or having close to the same performance Features are the first at home and abroad. 

2, GR composite titanium dioxide pigment particle surface properties of a crystalline TiO2, rutile crystal form stars and anatase titanium  dioxide so the product has the same or similar properties, such as: hiding power, whiteness, oil absorption. 

3, GR composite titanium dioxide and titanium dioxide pigment ratio: product particle size, particle size distribution is better, complex heterogeneous nature and low density, so that the product has a better dispersion and applicability in coating systems. 

4, consumption costs significantly lower than that of titanium dioxide, titanium dioxide product costs less than the 3000-5000 yuan / ton. 

5, the production process of environmental pollution, in line with national industrial policy for sustainable development. 

GR composite titanium dioxide pigment performance verification 

1, GR composite titanium dioxide pigment covering performance ratio of the coating properties of the coating is the most direct and most critical indicators reflect the performance of the white pigment in paint under the same conditions and the premise of the other components paint hiding power is stronger, the stronger hiding properties of the pigment. 

2, GR composite titanium dioxide pigments absorb ultraviolet light shielding performance of the GR composite titanium dioxide pigment (rutile) and rutile titanium dioxide (R818) water suspension dubbed 0.2% after 20 minutes by ultrasonic dispersion, the sample placed 72 UV and visible light transmittance spectrophotometer tested (see Table 4), in order to determine whether the product against UV  absorption. GR composite titanium dioxide pigments, rutile titanium dioxide, respectively, with water as the suspension of the laws of each wavelength monochromatic light transmittance and basically the same wavelength less than 400nm UV transmission are very low, with the wavelength of incident increases light transmittance of the suspension increased significantly, to 700nm reached more than 40%. Transmittance due to differences in the suspension can be approximated that the solid material itself caused by factors, so that the GR composite titanium dioxide pigment compared with rutile titanium dioxide, absorb ultraviolet light shielding effect are very strong. Rutile titanium dioxide to absorb ultraviolet light shielding effect is that it has embodied the best chemical stability and good anti-aging, anti-chalking and discoloration resistance, and optical properties similar to GR composite titanium dioxide pigment exhibits show the same with its anti-aging and other light stability. Through the above two experiments it can be seen: the use of GR composite titanium dioxide pigment in the coating system can be restricted with the titanium dioxide obtained the same or similar performance; 

GR composite titanium white pigment widely used in paint systems, improve coating performance, reduced significantly the cost of materials. Physical and chemical properties (Physical Properties)
