甲酚樹酯
英文
cresol resin-
By means of the elasto - plastic finite element method ( fem ), the effect of fillets on the stress distribution in aluminum alloy single lap joints was investigated under the condition of four types of adhesives with different elastic modulus ( i. e. acrylate, polyurethane, epoxy and phenolic - resin adhesives ) to form the fillets
摘要利用彈塑性有限元法,研究四種不同彈性模量的膠粘劑(丙烯酸酯膠、聚氨基甲酸乙酯膠、環氧樹脂膠和酚醛樹脂膠粘劑等)形成的膠瘤對鋁合金單搭接接頭應力分佈的影響。( 3 ) volume shrinkage of composite decreases greatly with wpu increasing, even can arrive a negative number, but thermal stability is still good. ( 4 ) toughening mechanism is that : the formation of high molecular linear amino formate construct is the toughening reason ; hydroxyl - terminated pu - prepolymer and pf react to produce chemical bond effect which participate cure ; carboxyl - terminated pu - prepolymer and pf form semi - ipn which make toughened pf occur maximum
( 4 )通過紅外光譜對pf / pu共混物分子結構進行的定性分析、以及掃描電鏡對沖擊斷面形貌進行的分析,可證明聚氨酯預聚物增韌酚醛樹脂的機理是:兩個體系都是由於高分子量的線形氨基甲酸酯結構而增韌;端羥基pu與pf在共固化中產生化學鍵效應,參與pf的固化;而端羧基pu則與pf形成半互穿網路而增韌。Determination of free ammonia in phenol - formaldehyde moldings
