研究了包覆凝聚法制备CR244粉末橡胶中,高分子树脂包覆剂组分、用量及2402树脂对所制备胶粘剂粘接性能的影响,同时对CR244粉末胶及片胶的溶解时间进行了比较。结果表明,M1、M2可提高胶粘剂的粘接强度;M3则会对粘接性能起到破坏作用。用包覆凝聚法制备的CR244粉末橡胶制备胶粘剂时仍可加入2402树脂,但用量应相对降低。用粉末胶代替传统片胶可大大缩短胶料溶解的时间,从而达到节能增效的目的。 The effects of composition and dosage of macromolecule resin coating agent and adhesion of 2402 resin on the prepared adhesive were studied. The dissolution time of CR244 powder adhesive and sheet adhesive were compared. The results show that, M1, M2 can improve the bonding strength of the adhesive; M3 will play a damaging role in adhesive properties. CR244 powder coating prepared by coating agglomeration method can still be added when the adhesive 2402 resin, but the amount should be relatively reduced. The use of powdered plastic instead of traditional glue can greatly shorten the time of rubber dissolving so as to achieve the purpose of energy saving and efficiency.
