Mortar admixture containing SiO2 aerogel as well as preparation method and application of mortar admixture
The invention belongs to the technical field of new building materials. The invention provides a mortar admixture containing SiO2 aerogel. The mortar admixture is prepared from the following components: 1 part of cellulose ether, 0.1 to 0.5 part of starch ether, 0.2 to 0.8 part of redispersible latex powder, 0.01 to 0.2 part of polyvinyl alcohol, 0.1 to 0.3 part of SiO2 aerogel particles, 0.1 to 0.2 part of potassium titanate whisker, 0.1 to 0.2 part of nano aluminum oxide and 0.01 to 0.5 part of foaming agent. The invention also provides a preparation method and application of the mortar admixture. According to the mortar admixture containing the SiO2 aerogel, disclosed by the invention, by adding the cellulose ether, the SiO2 aerogel particles with different particle sizes, the potassium titanate whiskers and the nano aluminum oxide, the thermal insulation, hydrophobic property and high-temperature resistance of thermal insulation mortar are improved.
本发明属于建筑新材料技术领域。本发明提供了一种含有SiO2气凝胶的砂浆外加剂，由如下组分组成：纤维素醚1份、淀粉醚0.1～0.5份、可再分散乳胶粉0.2～0.8份、聚乙烯醇0.01～0.2份、SiO2气凝胶颗粒0.1～0.3份、钛酸钾晶须0.1～0.2份、纳米氧化铝0.1～0.2份、发泡剂0.01～0.5份。本发明还提供了一种砂浆外加剂的制备方法和应用。本发明的含有SiO2气凝胶的砂浆外加剂通过加入纤维素醚、粒径不同的SiO2气凝胶颗粒、钛酸钾晶须和纳米氧化铝，提高了保温砂浆的保温、疏水以及耐高温性能。
