摘　　要：通过采用有机-无机复合改性剂对钠水玻璃粘结剂进行改性,提高了玻化微珠保温板的耐水性。研究了水玻璃固化方式、固化剂种类、水玻璃复合改性和KH560改性等对以钠水玻璃为主要粘结剂的玻化微珠保温板吸湿率和吸水量的影响。结果表明,复合改性剂的加入可有效提高玻化微珠保温板的耐水性,使其吸水量由2.25kg/m2降低到0.95kg/m2。This paper studies on improving waterproof property of glazed hollow bead insulation board by the organic-inorganic compound modification of adhesive. The influence of water glass curing methods,curing agents,water glass composite modification and KH560 modification on the hygroscopicity and water absorption rate were studied. The results show that compound admixture can effectively improve the water resistance of the hollow bead heat preservation formwork,and the water absorption rate was decreased from 2.25 kg/m^2 to 0.95 kg/m^2.
