Tóm tắt
STUDY ON THE MODIFYING EPOXY RESIN WITH SILANE COMPOUND FOR FABRICATION OF AVIATION HEAT-RESISTANT ADHESIVE
This paper presents some results of the study on modifying epoxy resin with dichloro diphenyl silane and developing heat-resistant adhesive from this modified resin. Some important specifications such as the tensile strength and the heat resistance of the adhesive based on modified epoxy and curing agent of low-molecular polyamide resin have been tested. The tested results have shown that the obtained adhesives began to decompose at 300°C, the tensile strength is 20.5 MPa. The obtained adhesives can be used as aviation heat-resistant adhesive, replacing some imported adhesives.
