Carbon fiber-based SiO2 aerogel foam cement and preparation method thereof
The invention belongs to the technical field of building material application, and relates to foam cement, and particularly relates to carbon fiber-based SiO2 aerogel foam cement and a preparation method thereof. The concrete comprises the following effective components in parts by weight: 60-80 parts of cement, 10-20 parts of carbon fiber-based SiO2 aerogel, 10-20 parts of porous ceramic powder,5-8 parts of a hydrogen peroxide foaming agent, 0.3-0.5 part of a foaming catalyst, 5-8 parts of a coagulant, 2-4 parts of a foam stabilizer, and the balance of water, wherein the carbon fiber-based SiO2 aerogel is the carbon fiber-based SiO2 aerogel provided by the claim 1, and water is added according to the water cement ratio of 0.46. According to the invention, the strength of the foam cementis enhanced by using the carbon fibers, and meanwhile, the technical problems of flat bubbles, small bubbles at the bottom of a mold, large bubbles at the top, uneven bubble distribution, a large number of microcracks on bubble walls and low closed-cell rate caused by hydrogen peroxide serving as a foaming agent are solved by using nano air holes formed by the carbon fiber-based SiO2 aerogel.
本发明属于建筑材料应用技术领域，涉及发泡水泥，尤其涉及一种碳纤维基SiO2气凝胶发泡水泥及其制备方法。按照重量份数包括以下有效成份：水泥60份～80份；碳纤维基SiO2气凝胶10份～20份；多孔陶瓷粉末10份～20份；双氧水发泡剂5份～8份；发泡催化剂0.3份～0.5份；促凝剂5份～8份；稳泡剂2份～4份；余量为水其中，所述碳纤维基SiO2气凝胶为权利要求1所提供的碳纤维基SiO2气凝胶，水的添加量按照水灰比0.46进行添加。本发明利用碳纤维增强发泡水泥的强度，同时，利用碳纤维基SiO2气凝胶所形成的纳米气孔填补双氧水作为发泡剂导致的气泡扁平、模具底部气泡小、顶部气泡大，气泡分布不均匀及气泡壁有大量微裂纹，闭孔率低的技术问题。
