Lightweight thermal insulation mortar as well as preparation method and application thereof
The invention discloses lightweight thermal insulation mortar as well as a preparation method and application thereof. The light thermal insulation mortar I provided by the invention comprises the following components in parts by weight: 150-260 parts of cement; 20 to 50 parts of modified glass beads; 30 to 60 parts of modified silica aerogel; 60 to 150 parts of light sand; 1-3 parts of redispersible latex powder; 1 to 1.5 parts of hydroxypropyl methyl cellulose ether; wherein the modified glass beads are obtained by modifying styrene butadiene rubber emulsion and a sulfur-containing silane coupling agent; the modified silica aerogel is formed by compounding chopped polypropylene fibers and silica aerogel. The modified glass beads and the modified silica aerogel are introduced and matched with other components, so that the prepared mortar has lower heat conductivity coefficient and higher compressive strength.
本发明公开了一种轻质保温砂浆及其制备方法和应用。本发明提供的轻质保温砂浆一包括如下按重量份计算的组分：水泥150～260份；改性玻化微珠20～50份；改性硅气凝胶30～60份；轻质砂60～150份；可再分散性乳胶粉1～3份；羟丙基甲基纤维素醚1～1.5份；其中，所述改性玻化微珠是通过丁苯橡胶乳液和含硫硅烷偶联剂改性得到；所述改性硅气凝胶是由短切聚丙烯纤维和硅气凝胶复合而成。本发明引入了改性玻化微珠和改性硅气凝胶，以及配合本发明的其他组分，使得制备的砂浆具有更低的导热系数和更高的抗压强度。
