Aerogel modified inorganic fiber adhesive and preparation process thereof
The invention relates to a preparation process of an aerogel modified inorganic fiber adhesive, and belongs to the technical field of aerogel modified inorganic fiber adhesives. The aerogel modified inorganic fiber adhesive comprises the following steps: 1) sequentially adding 10-140 parts of water, 1-15 parts of a stabilizer and 3-40 parts of an inorganic fiber adhesive into a container of a high-speed dispersion machine, then conducting stirring for 3-30 minutes at a speed of 300-1500 r/min at normal temperature and normal pressure, and uniformly conducting mixing to obtain a solution; and 2) adding 1-20 parts of aerogel powder, 0.1-10 parts of an organic silicon hydrophobic emulsion and 0.01-10 parts of a silane coupling agent into the solution obtained in the step 1), then conducting stirring for 10-60 minutes at a speed of 500-5000r/min at normal temperature and normal pressure, and uniformly conducting mixing to obtain slurry of the aerogel modified adhesive. The aerogel powder, the fiber resin adhesive and the water are mixed into a whole on the premise of not destroying the nano structure and the performance of the aerogel, so that the heat conductivity coefficient of the prepared mixed adhesive slurry is remarkably reduced after the mixed adhesive slurry is heated and cured, and the hydrophobic capacity is remarkably enhanced.
本发明专利涉及一种气凝胶改性无机纤维胶粘剂的制备工艺，属于气凝胶改性无机纤维胶粘剂技术领域。包括以下步骤：1）、将水10‑140份、稳定剂1‑15份、无机纤维胶粘剂3‑40份依次加入到高速分散机的容器内，然后在常温常压下以300‑1500r/min的速度搅拌3‑30分钟，混合均匀获得溶液；2）、将气凝胶粉体1‑20份，有机硅憎水乳液0.1‑10份、硅烷偶联剂0.01‑10份加入到步骤1）获得溶液中，然后在常温常压下以500‑5000r/min搅拌10‑60分钟，混合均匀获得气凝胶改性胶粘剂的浆料。本发明在不破坏气凝胶的纳米结构和性能的前提下，将气凝胶粉体、纤维树脂胶粘剂、水三者混合形成一个整体，使其制备的混合胶粘剂浆料升温固化后导热系数显著降低，疏水能力显著增强。
