Light-weight high-strength muck-based thermal insulation material and preparation method thereof
The invention discloses a light-weight high-strength muck-based thermal insulation material and a preparation method thereof. The light-weight high-strength muck-based thermal insulation material comprises the components in parts by mass: 45-55 parts of muck, 0-10 parts of fly ash, 25-35 parts of cement, 10-20 parts of polyphenyl particles, 5-10 parts of a foaming agent, 0.5-1.5 parts of a water reducing agent and 5-15 parts of aerogel. The preparation method comprises the steps: uniformly mixing the raw materials in proportion, adding the foaming agent, the water reducing agent and a proper amount of water, stirring to form slurry, adding the aerogel, stirring to form slurry, molding, and placing at the temperature of 20 DEG C-50 DEG C and curing. The thermal insulation material has the beneficial effects that the polyphenyl particles are used as lightweight aggregate, hydrogen peroxide is used as a foaming agent to increase the number of micropores of a matrix, and an aerogel modification technology is matched on the basis of a dual weight reduction scheme, so that the thermal insulation performance of the thermal insulation material can be effectively improved, and meanwhile, good mechanical properties are maintained; the thermal insulation material has the advantages of light weight, high strength, thermal insulation and energy conservation.
本发明公开了一种轻质高强渣土基保温材料及制备方法，其组分按质量份数计包括渣土45～55份、粉煤灰0～10份、水泥25～35份、聚苯颗粒10～20份、发泡剂5～10份、减水剂0.5～1.5份、气凝胶5～15份，制备方法包括：将原料按照配比混合均匀，然后加入发泡剂、减水剂和适量水搅拌成浆体，之后加入气凝胶搅拌成浆体后成型，最后放到20℃～50℃下进行养护。本发明的有益效果是采用聚苯颗粒作为轻质骨料，采用双氧水作为发泡剂增加基体微细孔数量，在双重减重方案基础上搭配气凝胶改性技术，可以有效提升保温材料的隔热性能，同时保持较好的力学性能；该保温材料具有轻质、高强、保温、节能的特点。
