Bi-component aerogel thermal insulation decorative mortar and preparation method thereof
The invention relates to the technical field of aerogel, in particular to bi-component aerogel thermal insulation decorative mortar and a preparation method thereof. The bi-component aerogel thermal insulation decorative mortar is prepared from the following components in parts by weight: a material A: 180 to 200 parts of white cement, 650 to 750 parts of sand, 20 to 25 parts of redispersible latex powder, 20 to 30 parts of silica fume, 3 to 5 parts of wood fiber, 2 to 5 parts of alkali inhibitor, 0.5 to 1 part of starch ether and 1.5 to 3 parts of hydroxypropyl methyl cellulose; and a material B: 22-25 parts of aerogel powder, 70-75 parts of glue, 2-5 parts of a dispersant and 0.5-1 part of propylene glycol. The aerogel and the decorative mortar are compounded, so that the effect of integrating heat preservation, heat insulation and decoration is achieved; according to the building glue, the aerogel powder is uniformly dispersed, so that environmental pollution caused by easy flying of the aerogel powder due to low density during use is avoided; the phenomenon of cracking of the decorative mortar layer caused by the composite aerogel powder is solved by utilizing the high cohesiveness of the glue, and meanwhile, high cohesive force between the decorative mortar layer and the wall surface is ensured.
本发明涉及气凝胶技术领域，更具体而言，涉及一种双组分气凝胶保温装饰砂浆及其制备方法。双组分气凝胶保温装饰砂浆包括以下重量份数的组成：A料：白水泥180‑200份、砂650‑750份、可再分散乳胶粉20‑25份、硅灰20‑30份、木质纤维3‑5份、阻碱剂2‑5份、淀粉醚0.5‑1份、羟丙基甲基纤维素1.5‑3份；B料：气凝胶粉体22‑25份，胶水70‑75份、分散剂2‑5份、丙二醇0.5‑1份。本发明利用气凝胶与装饰砂浆的复合，达到了保温隔热装饰一体化的效果；建筑胶水将气凝胶粉体进行分散均匀，避免了气凝胶粉体使用时由于低密度易飞散形成的环境污染；利用胶水的高粘结性解决了复合气凝胶粉体导致装饰砂浆层开裂的现象，同时保证装饰砂浆层与墙面之间有着高粘结力。
