CR/MMA/SBS三元接枝共聚胶粘剂的研制

Preparation of Adhesive of Three-units Graft Copolymerization of CR/MMA/SBS

针对CR和CR/MMA二元接枝共聚胶粘剂初粘力低、剥离强度低这一问题 ,研制了CR/MMA/SBS三元接枝共聚胶粘剂 ,并测定了该胶粘剂的有关物性 .结果表明 :该胶粘剂的粘结强度 (尤其是初粘强度 )和剥离强度有明显的提高 .

In allusion to the problem that CR adhesive and the adhesive of two unites graft copolymerization of CR/MMA are low felting and peeling intension,we prepared the adhesive of three units graft copolymerization of CR/MMA/SBS, and determined the properties of the adhesive. The results showed that felting and peeling intension (especially early felting intension) of the adhesive were obviously advanced. The effects of main reaction condition to the graft copolymerization are discussed.
