SiO2 aerogel composite thermal insulation material and preparation method thereof
The invention discloses a SiO2 aerogel composite thermal insulation material and a preparation method thereof.The SiO2 aerogel composite thermal insulation material is formed by mixing a component A and a component B. The component A is aerogel composite paste and comprises styrene-butadiene emulsion, silica fume, SiO2 aerogel, polyphenyl granule lightweight aggregate, HPMC and water, the component B is cement-based powder material, and the component B is cement-based powder material. Comprising P.II52.5 Portland cement, I-grade fly ash, ash calcium powder, a polycarboxylate superplasticizer, wood fibers and PP fibers, and solves the problems of small volume mixing amount, uneven mixing and hydrophobicity of SiO2 aerogel in a composite thermal insulation material, so that the SiO2 aerogel can be uniformly mixed with liquid to form a stable paste under the large volume mixing amount, and the composite thermal insulation material has good thermal insulation performance. Meanwhile, the powder can be uniformly mixed with the aerogel paste through stirring.
本发明公开了一种SiO2气凝胶复合保温材料及其制备方法，其中，SiO2气凝胶复合保温材料由A组分和B组分混合而成，A组分为气凝胶复合膏料，包括丁苯乳液、硅灰、SiO2气凝胶、聚苯颗粒轻骨料、HPMC和水，B组分为水泥基粉体材料，包括P.Ⅱ52.5硅酸盐水泥、Ⅰ级粉煤灰、灰钙粉、聚羧酸减水剂、木质纤维和PP纤维，本发明解决了SiO2气凝胶在复合保温材料中体积掺量小、混合不均及疏水问题，使SiO2气凝胶在大体积掺量下和液体能够均匀混合形成稳定的膏体，同时使粉料能够通过搅拌与气凝胶膏料均匀混合。
