摘　　要：研究了玻化微珠在隔热保温厚质腻子中的最佳、最大质量比,以及抗裂纤维、可再分散胶粉对隔热保温厚质腻子粘接强度的影响。重点研究了不同比例的玻化微珠改性剂对隔热保温厚质腻子的粘接强度的影响。结果表明:采取将不同粒径玻化微珠合理复配的方法,可以获得最大的体积密度、最低的容重、最低的导热系数。使用抗裂纤维、可再分散胶粉虽然可以提高粘接强度,但是提高幅度有限,不能满足产品技术要求。采用玻化微珠改性剂对玻化微珠表面进行改性,可以大幅度提高隔热保温厚质腻子的粘接强度,达到0.065 MPa,使腻子满足厚质涂装的要求。It was found in this article that there is an optimum and maximum mass ratio for glazed heads in heat insulation and preservation high build putty. The influence of crack resistant fiber and re - dispers- able latex powder on the adhesive strength of putty was studied, focusing on the effect of ratio of glazed beads mndifier on the adhesive slrengh of putty. The results showed that an optimum combination of glazed beads eouht lead to a maximum volume density, the lowest w^lume - weight and lowest heat conductivity. Use of crack resistant fiber and re - dispersible latex power could improve the adhesive strength, but only in a limit- ed range, which cannot meet the technical requirement. However, use of modified glazed bead can signifi- cantly increase the adhesive strength of putty, up to 0. 065 MPa, which meet the requirement for high build- ing finishing.
