【Abstract】 Using phenol, formaldehyde, exoxy-resin and poly etc. as materials and in the acid catalysing condition, one kind of new modified epoxy-resin is developed. Through the function evaluation and the applications used for grinding wheel and cutting piece, it shows that the coherent function, intensity and toughness of this glue all achieve the intemal advanced level comparing with the similar products. The emery wheel and cutting piece manufactured by this adhesive have fine functions.更多还原
