| Abstract: | The moisture-curable polyurethane hotmelt adhesives for autolamps were synthesized from polyol and diphenyl methane-4,4-diisocyanate （MDI）. The viscosity, viscosity stability and green strength of the adhesive were studied. The peel strength was 980 N/25 mm and thermal resistance was 180 ℃ when the crystalline polyester content was 10% and the thermoplastic polyester content was 15%. The hotmelt adhesive satisfied with the requirements of autolamps sealing and assembling. |
