additives in the rubber

oleophylic & hydrophilic additivesProduct introduction SQYS coupling agent is Jiashitai in Chongqing Institute of Applied plastic materials modified by long-term research, has developed a new type of functional coupling agent. Unique properties, especially for high water content and a large number of hydroxy-containing powder surface modification, can handle dry and wet powder of inorganic material. Models, characters, dosage and application Models Appearance Usage Dosag(%) Application ZF-101 White waxy solid Dry 0.5-2 Heavy calcium carbonate, wood (bamboo) powder, starch, Sodium Sulfate, calcium oxide, light calcium carbonate, magnesium hydroxide, such as aluminum hydroxide. Features This product is a result of three-dimensional network structure contains a group of parents, there is a good stability against hydrolysis. Can dissolve in water, can dissolve in organic solvents. Of inorganic powders and organic materials have a strong interface adhesion. Both for dry processing, wet processing can also be used for powders with low moisture content also modified the effect of coupling. Of high moisture content and a large number of hydroxy-containing powder has good compatibility and dispersion can significantly reduce the viscosity of filler system to improve the mechanical properties of composite materials and processing performance. When used in a transparent masterbatch, transparent masterbatch can enhance transparency and in the products of mechanical strength. Masterbatch for the moisture absorption can increase the dispersion, reduction or removal of products, and marks the surface of spent grain points. For the heavy calcium carbonate, talc, barite, calcium sulfate anhydrous when Masterbatch, Masterbatch make a translucent or transparent. Usage Dry processing u Pretreatment method: high-speed mixer in powder mixing by adding coupling agents are not subject to restrictions under the expected temperature, activation time greater than 5 minutes to the expected temperature of 120-140 centi-degree appropriate. u Direct modification method: in plastic, rubber products, such as the production process can be mixing in the filler and the polymer coupling agent when adding the order of the first filler, coupling agent and a small amount of plasticizers, lubricants, antioxidants, etc. organic additives, and then adding an organic polymer to form a composite material. u In the paint, ink, pigment production (for ensure it will dissolve ,the temperature will be 60 centi-degree above )can be directly used as a dispersant. Wet processing u The measurement of the coupling agent in the container by adding 8-10 times the uniform mixing of water (preferably water temperature 60-80 centi- degree). u Put the prepared coupling agent in aqueous solution under stirring slurry fully (> 30min) ,after modify ,drying dehydration. u After the measured coupling agent is dissolved by the hot water (usually by dry powder of 0.1-0.3%) in the second dry before spraying on the powder, the dynamics of cyclones, such as dry, so as to achieve full activation of the effect.
