摘要
国家建筑节能标准的提高对传统的外墙保温材料提出了更高要求.为了改善外墙保温材料的保温性能和物理力学性能,通过向保温粘结砂浆中掺加亲水性聚苯颗粒(EPS)等材料,针对不同配合比的改性EPS保温砂浆进行试验研究,确定了改性EPS保温砂浆的最优配合比.试验研究表明:在传统保温砂浆中掺加改性材料,可在满足保温砂浆粘接性能的基础上,改善砂浆的导热系数和软化系数,达到外墙永久性保温砌模材料各项性能指标要求,并满足国家关于寒冷地区节能65%的相关标准对材料保温性能的要求.
The improvement of building energy standard presents more requirement for traditional external wall thermal insulating material in China.In order to improve the thermal and mechanical properties of thermal insulating material,hydrophilic expandable polystyrene granules was added to thermal insulating material,which is called modified EPS thermal insulating mortar.Then experimental investigation was conducted on modified EPS thermal insulating mortar with different mix proportion of hydrophilic expandable polystyrene granules.Finally,the optimum mix proportion of modified EPS thermal insulating mortar was achieved.The experimental results indicate that： the thermal conductivity and softening coefficient of thermal insulating mortar can be improved by adding modified material to traditional thermal insulating mortar.The modified EPS thermal insulating mortar can not only meet the requirements of external wall perpetual thermal insulating material,but also satisfy the requirements of thermal insulation property in Chinese cold area.
