Ultra-light organic-inorganic composite thermal insulation material and preparation method thereof
The invention discloses an ultra-light organic-inorganic composite thermal insulation material and a preparation method thereof. The ultra-light organic-inorganic composite thermal insulation material disclosed by the invention is mainly prepared from the following components in parts by weight through a pressurization foaming-pressure relief foaming process: 42 to 55 parts of sulphoaluminate cement, 12 to 16 parts of fly ash, 7 to 11 parts of silica fume, 0.2 to 0.5 part of rubber powder, 4.3 to 5.1 parts of a compound foaming agent, 0.3 to 0.5 part of a compound foam stabilizer, 0.15 to 0.25 part of a water reducing agent and 21 to 36 parts of water. A large number of stable and uniform bubbles are introduced into the organic-inorganic composite material under the pressurization condition through the pressurization foaming-pressure relief foaming technology, then a large number of uniform and stable pressurization bubbles are evenly mixed with the cement slurry to obtain the foaming slurry, in the pressure relief process, the bubbles in the pressurization foaming slurry are evenly expanded, the ultra-light design is achieved, and the foaming effect is good. Wherein the volume weight of the prepared ultra-light organic-inorganic composite thermal insulation material can reach 100-150kg/m < 3 >, and the heat conductivity coefficient is less than or equal to 0.065 W/(m.K).
本发明公开了一种超轻质有机‑无机复合保温材料及其制备方法。本发明的超轻质有机‑无机复合保温材料，按重量份计，主要由以下组分通过加压制泡‑泄压发泡工艺制得：硫铝酸盐水泥42‑55份，粉煤灰12‑16份，硅灰7‑11份，胶粉0.2‑0.5份，复配发泡剂4.3‑5.1份，复配稳泡剂0.3‑0.5份，减水剂0.15‑0.25份，水21‑36份。本发明通过加压制泡‑泄压发泡工艺，在加压条件下，向有机‑无机复合材料中引入大量稳定均一的气泡，然后大量均一、稳定的加压气泡与水泥浆料混合均匀得到发泡浆体，在泄压过程中，加压发泡浆体内部气泡均一膨胀，实现超轻化设计，其中，所制备的超轻质有机‑无机复合保温材料的容重可以达到100‑150kg/m3，导热系数≤0.065W/(m·K)。
