一、前言无机胶粘剂是无机非金属材料的一种,它在国民经济中所起的作用已越来越受到各国的重视。磷酸盐系、碱金属硅酸盐系以及硅溶胶等是具有代表性的无机胶粘剂。碱金属硅酸盐系这一类胶粘剂如;K_2On、SiO_2、NaO.N.SiO_2等适合中温条件下使用;而磷酸盐系胶粘剂如:Al(H_2PO_4)_3、Zn(H_2PO_4)_2和Mg(H_2PO_4)_3,等存在价格太高等缺点。为此,我所从1983年起开展了GJ一90耐高温无机胶粘剂在研
I. INTRODUCTION Inorganic adhesives are a kind of inorganic non-metallic materials. Their role in the national economy has drawn more and more attention from all the countries. Phosphate, alkali silicate and silica sol are typical inorganic adhesives. Alkali metal silicate is a kind of adhesive such as K 2 O n, SiO 2, NaO.N.SiO 2, which is suitable for use under moderate temperature. Phosphate adhesives such as Al (H 2 PO 4) 3, Zn (H 2 PO 4) 2 and Mg (H 2 PO 4 ) _3, etc. There are disadvantages such as the price is too high. To this end, I since 1983 launched a GJ a 90 high temperature inorganic adhesives in the study
