一种氧化铝和氧化铜气凝胶发泡水泥
摘要：
本发明提供的氧化铝和氧化铜气凝胶发泡水泥包括按质量份计的下述组份：普通硅酸盐水泥，30～65份；氧化铝气凝胶，5～15份；氧化铜气凝胶，5～15份；微硅粉，4～10份；促凝剂，2～4份；减水剂，2～4份；稳泡剂，4～8份；发泡剂，5～15份；粉煤灰，5～25份。和现有技术比，本发明提供的发泡水泥导热系数为0.075～0.095W/(m·K)，吸音能力为0.10～0.25％，干体积密度为250～500kg/m3，抗压强度为3.5～5.0Mpa，且还具有较好的防水性、收缩率低、寿命长及施工简单易操作。
摘要（英）：

The invention provides alumina and copper oxide aerogel foam cement. The alumina and copper oxide aerogel foam cement is prepared from the following components in parts by mass: 30 to 65 parts of ordinary Portland cement, 5 to 15 parts of alumina aerogel, 5 to 15 parts of copper oxide aerogel, 4 to 10 parts of silica fume, 2 to 4 parts of coagulation accelerator, 2 to 4 parts of water reducing agent, 4 to 8 parts of foam stabilizer, 5 to 15 parts of foaming agent and 5 to 25 parts of fly ash. Compared with the prior art, the foam cement provided by the invention has the advantages that a heat conductivity coefficient is 0.075 to 0.095W/(m.K), the sound absorbing power is 0.10 to 0.25 percent, the desiccated bulk density is 250 to 500kg/m<3>, and the compressive strength is 3.5 to 5.0Mpa; in addition, the alumina and copper oxide aerogel foam cement has the advantages of better water resistance, low shrinking percentage, long service life, simple construction and easiness in operation.
