The invention belongs to the technical field of building materials, and discloses a preparation method of a gypsum-based building external wall thermal insulation material. The preparation method comprises the following steps: (1) soaking rubber powder in a diamino silane coupling agent aqueous solution, taking out, mixing with polyvinyl ester type epoxy resin and EVA emulsion, carrying out heat treatment, and cooling to obtain modified rubber powder, (2) mixing 3-5 parts by weight of a waterproof agent, 0.5-2 part by weight of aluminum powder, 4-8 parts by weight of hydrated calcium sulphoaluminate, 0.5-1 part by weight of nano silicon dioxide and 60-80 parts by weight of water, adding 8-15 parts by weight of modified rubber powder, uniformly stirring, and drying, and (3) adding the wasteglass fiber reinforced plastic powder and the material dried in the step (2) into slurry prepared from the building gypsum, and uniformly stirring. According to the method, a diamino silane couplingagent is firstly used for soaking the rubber powder, then polyvinyl ester type epoxy resin and EVA emulsion are added for modification treatment, the binding force of the rubber powder and a gypsum material is improved, it is guaranteed that the strength of a gypsum base material is not reduced, and the heat preservation performance is improved.
本发明属于建筑材料技术领域，公开了一种石膏基建筑外墙保温材料的制备方法。本发明的制备方法包括以下步骤：(1)将橡胶粉于双氨基硅烷偶联剂水溶液中浸泡后取出，与聚乙烯酯型环氧树脂和EVA乳液混合，热处理后冷却得改性橡胶粉；(2)按重量份数计，将3‑5份防水剂、0.5‑2份铝粉、4‑8份水化硫铝酸钙、0.5‑1份纳米二氧化硅和60‑80份水混合，加入改性橡胶粉8‑15份，搅匀后干燥；(3)将废玻璃钢粉和步骤(2)干燥所得的物料加入到建筑石膏所制料浆中搅拌均匀。该方法先使用双氨基硅烷偶联剂浸泡处理橡胶粉，再加入聚乙烯酯型环氧树脂和EVA乳液改性处理，提高了橡胶粉与石膏材料的结合力，保证了石膏基材的强度不降低，且保温性能有所提升。
