The invention discloses a preparation process of an energy-saving thermal insulation material, and belongs to the technical field of thermal insulation materials, the preparation process comprises the following steps: stirring cement, fly ash, mineral powder, an activator Na2SO4, an MN-I I type superplasticizer and hydroxypropyl methyl cellulose to obtain a cementing material; and adding an AC foaming agent and water into the cementing material, stirring, adding the hydrophilic modified polystyrene particles, stirring, pouring into a mold, carrying out drying pretreatment, and foaming to obtain the energy-saving thermal insulation material. According to the invention, the hydrophilic modified polystyrene particles are used as the lightweight aggregate and are mixed with the cementing material for foaming, so that the binding power of the hydrophilic modified polystyrene particles and the cementing material is improved, and the situation that the mechanical property of the finished thermal insulation material is poor due to the fact that polystyrene floats upwards in the stirring and forming process due to the small density is effectively prevented.
本发明公开了一种节能保温材料的制备工艺，属于保温材料技术领域，包括如下步骤：将水泥、粉煤灰、矿粉、激发剂Na2SO4、MN‑I I型高效减水剂、羟丙基甲基纤维素，搅拌，得胶凝材料；向胶凝材料中加入AC发泡剂、水，搅拌后，加入亲水改性聚苯乙烯颗粒，搅拌，倒入模具进行干燥预处理后进行发泡，得一种节能保温材料。本发明通过以亲水改性聚苯乙烯颗粒作为轻骨料，与胶凝材料混合发泡，提高了亲水改性聚苯乙烯颗粒与胶凝材料的粘结力，有效防止聚苯乙烯因密度较小在搅拌成型过程中出现上浮，导致成品保温材料力学性能较差。
