A one-coat adhesive composition which utilizes environmentally acceptable ingredients and which can withstand high temperature conditions such as those experienced during injection molding processes. The adhesive contains a Diels-Alder adduct of a perhalogenated cyclic conjugated diene and an olefinically unsaturated dienophile having a vinyl content in excess of 50 percent, a phenolic resin, an aromatic hydroxy compound, a formaldehyde donor, a heat-activated unsaturated elastomer crosslinker, a vulcanizing agent, and a metal oxide. An adhesive bond prepared with the adhesive is resistant to high temperature fluids and corrosive agents.
一种单涂层粘合剂组合物,它使用环境可接受的成分,并能承受高温条件,如注塑成型过程中的高温条件。该粘合剂含有过卤化环共轭二烯和
乙烯基含量超过 50% 的烯烃不饱和亲二烯的 Diels-Alder 加合物、
酚醛
树脂、芳香族羟基化合物、
甲醛供体、热活化不饱和弹性体
交联剂、
硫化剂和金属氧化物。用这种粘合剂制备的粘合剂具有耐高温流体和腐蚀性介质的性能。
