47.一种可作为高级橡胶产品补强填料的硅铝炭黑(CN1172127A) 本发明涉及一种可作为高级橡胶产品补强填料的硅铝炭黑。所用的原料为煤矸石或过火煤矸石,原料经选料→除铁→粉碎→焙烧→加入偶联剂→脱硫→缺氧冷却→细磨→包装后制成产品。所制得的硅铝炭黑产品有黑色、白色和其它彩色。由于在工艺过程中采用了除铁、脱硫、加入偶联剂和在缺氧的条件下冷却等工艺,使所制得的炭黑在橡胶产品中可以起增粘作用,具有防烧焦和提高伸长性的作用,增加了补强性能。生热低、抗老化性能好,胶与线的结合力增加。可以用于汽
47. A silica-alumina carbon black (CN1172127A) as a reinforcing filler for high-grade rubber products. The present invention relates to a silica-alumina carbon black which can be used as a reinforcing filler for high-grade rubber products. The raw materials used are coal gangue or over-fired coal gangue, and the raw materials are selected by the following methods: removing iron → smashing → roasting → adding a coupling agent → desulfurization → anoxic cooling → fine grinding → packaging to make a product. The silica-silica carbon black products produced are black, white and other colors. Because the process of removing iron, desulfurizing, adding a coupling agent and cooling under anoxic conditions are used in the process, the prepared carbon black can play a tackifying effect in a rubber product, and has anti-burning charring and improvement. The effect of elongation increases the reinforcing properties. Low heat generation, good anti-aging properties, and increased adhesive force of the glue and thread. Can be used for steam
