摘 要:以膨胀珍珠岩和微珠保温砂岩为对象,通过实验法获得了不同骨料级配下膨胀玻化微珠无机保温砂浆,并分析研究了材料的吸水特性、保温骨料、纤维用量等变量对无机保温砂浆的使用性能的影响。结果表明,随玻化微珠掺量的增加,无机保温砂浆干密度不断增加,孔隙率表现出先下降后上升的变化趋势,当m(膨胀珍珠岩)∶m(玻化微珠)为1∶1.5时,孔隙率最小,最小值为0.236。当保温骨料为60%,可分散乳胶粉为3.8%,纤维素醚掺量为0.25%,引气剂用量为0.028%时,无机保温砂浆的导热系数、强度和干密度值满足标准要求。 Abstract: Taking expanded perlite and microbeads as the objects, the inorganic thermal insulation mortar with expanded glass bubbles under different aggregate grades was obtained by experimental method, and the application performance of inorganic thermal insulation mortar was analyzed and studied according to the water absorption characteristics of materials, the amount of thermal insulation aggregate and the amount of fiber. The results show that, with the increase of glass bubbles, the dry density of inorganic thermal insulation mortar increases continuously, and the porosity shows a change process of decreasing first and then rising. When the mass ratio of expanded perlite to glass bubbles is 1∶1.5, the porosity is the smallest and the minimum is 0.236. When the thermal insulation aggregate is 60%, dispersible latex powder is 3.8%, cellulose ether is 0.25%, and the amount of air attractant is 0.028%, the thermal conductivity, strength and dry density of the inorganic thermal insulation mortar meet standard requirement.

(1)随玻化微珠的增加,无机保温砂浆干密度不断增加,孔隙率表现出一个先下降后上升的变化过程,当m(珍珠岩)∶m(玻化微珠)为1∶1.5时,孔隙率最小,最小值为0.236。

(2)当保温骨料为60%,可分散乳胶粉为3.8%,纤维素醚掺量为0.25%,引气剂用
量为0.028%时,无机保温砂浆的导热系数、强度和干密度值在满足相关标准的前提下,取得较好的使用性能。
