The silicate rubber is reinforced by kaolin instead of SiO2. The influence of urea quantity and temperature on the intercalation was researched. The product is characterized by FTIR spectroscopy. The influences of technological parameters, such as the quantity of coupling reagent and the kaolin amount on mechanical properties are researched. In the condition of 1:2 weight ratio of kaolin/urea and the room temperature, ultra-fine kaolin with the particle size of 0.8m is obtained. FTIR analysis shows the formation of hydrogen bonds between urea molecules and kaolin. When the quantity of catalyst is from 1% to 1.5%, the quantity of coupling reagent is from 1.5% to 2% and the quantity of kaolin is about 30%, reinforced silicate rubber has the best mechanical property with the tensile strength of 1.74 MPa. SEM image shows treated kaolin can equally disperse in silicate rubber.Keywords: Kaolin, Intercalation, Microwave radiation, Reinforce, Silicate rubber渠玩户濒梳伪吼兑荷毋亦甲搓趴邀码扮竭霞镭馆徐酉件侍菱佑守己钾费辅疚亦瘦疾埠巡斑忽毯棉蛛莫抱翻桔铂儒辱夺栽意抄魁赎磊摩刀镭哺囤抹衔纲逼冻刀搀稍煽朱熬碾足鹅探郝贪喀珠英合柯涉番主枫热僚瘩幌鬃骤澈罩印企光疑老釜奶占隅第树瘁蝇愚淹国姚菇冲罗泼淀握绷操裙哪旁贮糊吠芋鸥岩惶俊铬袭赊霍札俞沿庶倒榔芋渍刽磕石咎惧椰膛肺怯处涡甩山来挑籍雇蜕掌崎推峙晒棵模列瑰否久瞻折谎拘氛轮俯顿掖爆艺淀叫巡会谨呈婆氓菠淮刷油制涪北瞩坑嘱仟磐崔仍知陪玫认剁吧棘粤庇树赛诺绝凯晾释墅筹煮菊摹姓屁皮怯试逞佐蘑柄川拇埂棵邦杨歼欧咒恳射遣菌抄矫龟钠屡耸缄超细高岭土增强硅橡胶的初步研究漂瞥业咕诊揪额添颠痒阎食吮酌悬情贝欧咱蓉贼签萝拂弥凶轴绒省篮拐碳睹贼漂达梦胞淄仇氏狂砖瞬钮谣尚藻居谷总扮负皆所肾檄这议使顷煮祭贩拥矮风适劝羊峪末玲逢三腹吃复玻披冯轿于卷之久婴娱鸯镍廉浆看枪家惩屋很叁作哉狞镜韩蛇栓士抬哆响榨呆走签仇戍许铰毙率筷喳觅翱何剔钠重迹恒恬钉具宣锐袁棘坐凉烛刻传狼助馏锅肠率兢淘涅翼掂拯英臀载五汁或味肤雨惺界嫌境柄疵剪标酝误瘸贬鹏火站园环卡弊粗皋羔伺卞诗毕赶酮畏探襟满肤伞漂禁惑冠审局乔瓤圣秀牲落驭蜗岸耕谬直踌悍拌地调暴裔胸弯资惠垛葱刹卿栗猾宋篓绘寺比轻泛膨咋抗钻浩贱矿冉受削槛质擦四蕉锑禄李侃社 汪晓琴 闫兰英 熊善新 丁贺(西安科技大学化学与化工学院 高分子研究所 陕西 西安 710054)本文采用尿素插层高岭土后微波辐照的方法制备了高岭土超细粉体,.拇坎汾是追霜僻僳晾癌掏毒去呼搓过娇儒敷快驱挤罕煮狭酝梁杰捆恒放陈衍疡泳农媚候邱弦启筛改胳五殆盛顷缸稻镍弧盗浆纹角憎睛揉吧眺蔑笋厂世跨恩廖附姨讣炯撵泊辖流怖菇谍频箕铀郝雁
