Modified silk fibroin reinforced fiber calcium silicate thermal insulation material and preparation method thereof

The invention belongs to the technical field of building materials, and discloses a modified silk fibroin reinforced fiber calcium silicate thermal insulation material and a preparation method thereof. According to the invention, a silk fibroin solution containing calcium chloride and a sodium silicate emulsion are rapidly mixed at a certain flow rate in a manner of dissolving and then mixing, such that modified silk fibroin reinforced fibers are obtained; and adding the obtained fiber into a calcium silicate thermal insulation material to obtain the modified silk fibroin reinforced fiber calcium silicate thermal insulation material. The method is simple in process, easy to operate, high in practicability and suitable for industrial application and popularization. 本发明属于建筑材料技术领域，公开了一种改性丝素蛋白增强纤维硅酸钙保温材料及其制备方法。本发明采用先溶解再混合的方式将含有氯化钙的丝素蛋白溶液和硅酸钠乳浊液在一定流速下快速混合，得到改性丝素蛋白增强纤维；再将所得纤维加入硅酸钙保温材料中，得到改性丝素蛋白增强纤维硅酸钙保温材料。本发明工艺简单易操作，实用性强，适宜工业的推广应用。
