【摘要】 以两种通用牌号的有机硅树脂为基料,制备出一种能耐700℃的高温涂料,并对低熔点玻璃粉、滑石粉、铝粉和硅烷偶联剂在有机硅耐高温涂料中的作用机理以及对涂料性能的影响进行了讨论。试验发现,有机硅树脂、低熔点玻璃粉、铝粉、滑石粉、硅烷偶联剂质量分别为30~50 g、20~30 g、1.5~6.0 g、10 g和1.5 g时涂层性能最佳。更多还原

【Abstract】 A kind of high temperature organic silicone coating that can resist 700?℃ was prepared.Two general trademark silicone resins were used.The effect of the low melting-point glass powder,talcum powder,aluminium powder and the silicon alkyl coupling agent on the performance of the coating and their mechanism of action were studied.The results showed that the performance of the coating is best when the mass of organic silicone resin,low melting-point glass powder,talcum powder,aluminium powder,and silicon alkyl coupling agent is(30～)50?g,20～30?g,1.5～6.0?g,10?g and 1.5?g,respectively.更多还原
