The invention discloses a thermal insulation material for a building external wall. The thermal insulation material is prepared from the following raw materials in parts by weight: 25-40 parts of modified expanded polystyrene, 30-40 parts of fly ash, 100-110 parts of Portland cement, 10-20 parts of a flame retardant, 10-15 parts of glass fibers, 75-100 parts of an elastic emulsion and 1-5 parts ofa binder. The invention further discloses a preparation method of the thermal insulation material for the building external wall. The expanded polystyrene granule molecules are spherical molecules and are stable in structure and compact molecules, so that the methoxypolyethylene glycol can be grafted to the surfaces of the expanded polystyrene granules, hydrophilic groups can be given to the expanded polystyrene granules, the hydrophilic performance of the expanded polystyrene granules is enhanced, and the methoxypolyethylene glycol is usually used as a raw material of a cement superplasticizer and can provide relatively strong dispersing performance for cement granules, and therefore, the stability of slurry can be improved after the prepared modified expanded polystyrene granules are mixed with cement.
本发明公开一种建筑外墙用保温材料，由如下重量份原料制成：25‑40份改性聚苯，30‑40份粉煤灰，100‑110份硅酸盐水泥，10‑20份阻燃剂，10‑15份玻璃纤维，75‑100份弹性乳液，1‑5份粘结剂；本发明还公开了一种建筑外墙用保温材料的制备方法；聚苯颗粒分子为球状分子，本身结构稳定为紧密型分子，所以聚乙二醇单甲醚能够接枝在聚苯颗粒表面，一方面能够为聚苯颗粒赋予亲水基团，增强其亲水性能，另一方面聚乙二醇单甲醚常被用于作为作水泥高效减水剂的原料，能够为水泥颗粒提供较强的分散性能，所以当制备出的改性聚苯颗粒与水泥混合后一能够增加浆液的稳定性。
