The invention belongs to the technical field of building energy conservation, and discloses a preparation method of rubber powder polyphenyl granule thermal insulation mortar. The preparation method comprises the following steps: (1) crushing plant straws, putting the crushed plant straws into lime slurry, and adding a citric acid aqueous solution and a phosphate solution to prepare modified plantfibers; (2) soaking the rubber powder in an aqueous solution of a diaminosilane coupling agent, mixing the soaked rubber powder with a styrene-butadiene emulsion and an EVA emulsion, carrying out heat treatment, and cooling to obtain modified rubber powder; (3) mixing the graphene oxide aqueous solution with the polyphenyl particles to obtain modified polyphenyl particles; and (4) mixing and stirring ordinary Portland cement and a silane coupling agent, adding starch sulfate grafted acrylic acid, the modified plant fiber, the modified rubber powder and the modified polyphenyl particles, thenadding fly ash, silica fume and water, and stirring and mixing to obtain the rubber powder polyphenyl particle thermal insulation mortar. According to the preparation method, the plant straw, the rubber powder, the modified polyphenyl granules and the ordinary Portland cement are modified, so that the strength and the thermal insulation property of the material are relatively ideal.
本发明属于建筑节能技术领域，公开了一种胶粉聚苯颗粒保温砂浆的制备方法。所述制备方法包含：（1）取植物秸秆粉碎放入石灰浆中，加入柠檬酸水溶液和磷酸盐溶液，制备改性植物纤维；（2）橡胶粉于双氨基硅烷偶联剂水溶液中浸泡后与丁苯乳液和EVA乳液混合，热处理后冷却得改性橡胶粉；（3）氧化石墨烯水溶液和聚苯颗粒混合得改性聚苯颗粒；（4）将普通硅酸盐水泥和硅烷偶联剂混合搅拌，加入淀粉硫酸酯接枝丙烯酸、改性植物纤维、改性橡胶粉和改性聚苯颗粒，再添加粉煤灰、硅灰和水，搅拌混合得胶粉聚苯颗粒保温砂浆。该制备方法通过对植物秸秆、橡胶粉、改性聚苯颗粒和普通硅酸盐水泥进行改性，使得材料强度和保温性能都比较理想。
