摘要： A two part polyurethane adhesive system and method of using the adhesive to bond polyurethane foams, polystyrene foams, and other substrates. The first part of the adhesive system is a hydrophilic polyurethane prepolymer prepared by reacting a high molecular weight, multi-functional polyol which has been copolymerized randomly from propylene oxide and ethylene oxide, with a diisocyanate or polyisocyanate. This reaction mixture is then diluted with either a flame retardant, a plasticizer, a solvent which is not considered a low flash point volatile organic compound, or a combination of these chemicals. The second part of the adhesive system is an aqueous phase curing agent. In addition to water, the components of the aqueous phase may include a tackifying agent or a catalyst or both. The method of bonding using the adhesive essentially comprises applying the polyurethane prepolymer to one of the substrates which is to be bonded, applying the aqueous phase curing agent to the polyurethane prepolymer, and placing the second substrate in contact with the prepolymer. The prepolymer and the aqueous phase curing agent may be applied sequentially or simultaneously.
摘要翻译：双组分聚氨酯粘合剂系统和使用粘合剂粘合聚氨酯泡沫，聚苯乙烯泡沫和其它基材的方法。粘合剂体系的第一部分是通过将已经从环氧丙烷和环氧乙烷随机共聚的高分子量多官能多元醇与二异氰酸酯或多异氰酸酯反应制备的亲水性聚氨酯预聚物。然后将该反应混合物用阻燃剂，增塑剂，不被认为是低闪点挥发性有机化合物的溶剂或这些化学品的组合进行稀释。粘合剂体系的第二部分是水相固化剂。除了水之外，水相的组分可以包括增粘剂或催化剂或两者。使用粘合剂的粘合方法基本上包括将聚氨酯预聚物施加到要结合的基材之一中，将水相固化剂施加到聚氨酯预聚物上，并将第二基材与预聚物接触。预聚物和水相固化剂可以顺序地或同时地施加。

摘要： A method of bonding a roof tile (10) to a roof substrate (56) utilizing a two component polyurethane foam (16). The method includes the step of applying under low pressure a stream (18) of a two component foamable liquid polyurethane (16) on a roof substrate ((56). Preferably, the foamable liquid polyurethane (16) has a density in the range of about one and one-half to about two pounds per cubic foot and a reactivity period in the range of about one and one-half to about four minutes. Preferably, the foamable liquid polyurethane (16) is applied at a rate of about two to about three pounds per minute. The roof tile (10) is placed into contact with the foamable liquid polyurethane (16) during the reactivity period of the foamable liquide polyurethane (16).
摘要翻译：一种使用双组分聚氨酯泡沫（16）将屋顶瓦（10）结合到屋顶基底（56）的方法。该方法包括在低压下将双组分可发泡液体聚氨酯（16）的流（18）施加在屋顶基材（56）上的步骤。优选地，可发泡液体聚氨酯（16）的密度范围为约一至半至约两磅/立方英尺，反应时间为约一至二分之一至四分钟。优选地，可发泡液体聚氨酯（16）以约二至一在可发泡液体聚氨酯（16）的反应期间，屋顶瓦（10）与可发泡液体聚氨酯（16）接触。
