Decoration waste aerogel mortar with thermal insulation and fireproof performance and preparation method thereof
The invention discloses decoration waste aerogel mortar with heat preservation and fireproof performance and a preparation method of the decoration waste aerogel mortar. The aerogel mortar is prepared from the following raw material components in parts by weight: 104 to 106 parts of slag, 4.5 to 4.7 parts of NaOH, 37.4 to 37.6 parts of Na2SiO3, 17.08 to 51.25 parts of decoration waste recycled fine aggregate, 34 to 35.7 parts of distilled water, 10.5 to 13.5 parts of SiO2 aerogel, 1.2 to 1.3 parts of methyl cellulose ether, 1.2 to 1.3 parts of latex powder, 0.3 to 0.4 part of polypropylene fiber, 0.1 to 0.15 part of air entraining agent and 0.21 to 0.27 part of silane coupling agent. According to the invention, the slag is used as the cementing material, CO2 emission is effectively reduced, the aerogel is used as the lightweight aggregate, so that the mortar has good thermal insulation and fireproof performance, and the decoration garbage is used for replacing the aerogel as the lightweight aggregate, so that the working requirements of the mortar are met, and the production cost is reduced. By means of the innovation, resource utilization of solid waste decoration garbage is achieved, the problem of environmental pollution caused by random stacking of the decoration garbage is solved, and the method not only has good social and economic benefits, but also conforms to the concept of sustainable development.
本发明公开了一种具有保温和防火性能的装修垃圾气凝胶砂浆及其制备方法，所述气凝胶砂浆原料组分包括，所述气凝胶砂浆原料组分包括矿渣104～106份、NaOH 4.5～4.7份、Na2SiO337.4～37.6份、装修垃圾再生细骨料17.08～51.25份、蒸馏水34～35.7份、SiO2气凝胶10.5～13.5份、甲基纤维醚1.2～1.3份、乳胶粉1.2～1.3份、聚丙烯纤维0.3～0.4份、引气剂0.1～0.15份以及硅烷偶联剂0.21～0.27份。本发明采用矿渣作为胶凝材料，有效减少了CO2排放，通过使用气凝胶作为轻骨料，使砂浆具备良好的保温和防火性能，用装修垃圾替代气凝胶作为轻骨料，既满足了砂浆的工作要求，又降低了生产成本。这一创新实现了固体废弃物装修垃圾的资源化利用，缓解了装修垃圾随意堆放所带来的环境污染问题，此举不仅具备良好的社会和经济效益，也符合可持续发展理念。
