The moisture-curing PUR(polyurethane hot melt adhesive) was prepared when polyester polyol,polyether polyol and MDI(4,4'-diphenyl methane diisocyanate) were used as main raw materials,carbon black was used as filler,and its aging-resistance was investigated.The research results showed that the moisture-curing PUR had the relatively better combination property when mass fractions of —NCO and carbon black were 2.8%and 1.5% respectively in prepolymer because the 180° peeling strength between PC(makrolon) subst...
