摘要
Abstract
A phenol-formaldehyde resin adhesive was synthetized and modified with epoxy resin and organo-silicon. The effects of adding stage, species and dosage of epoxy resin and organo-silicon dosage on the properties of the phenol-formaldehyde resin adhesives were studied. The products were characterized by means of FTIR and TG-DSC. The results showed that the phenol-formaldehyde resin adhesive modified with about 1.5%(w) (based on the mass of system) bisphenol A epoxy resin(E51) and about 0.6%(w) (based on the mass of system) hydroxypropyl polydimethylsiloxane(organo-silicon 8427) before reflux had modest viscosity and good flexibility, with 0.037%(w) formaldehyde and 7.1 MPa tensile shear strength. The flexibility and thermal resistance of the modified phenol-formaldehyde resin adhesive are better than those of unmodified one.关键词
