Concrete microorganism self-repairing material and preparation method thereof
The invention discloses a concrete microorganism self-repairing material and a preparation method thereof. The concrete microorganism self-repairing material comprises microorganism starch microspheres, water-absorbent resin, silicon dioxide, calcium oxide and calcium phosphate. The microbial starch microspheres are prepared by crosslinking microbial components and modified starch; the modified starch is prepared by carrying out grafting reaction on silylene phosphate and starch; the silylene phosphate has a structure as shown in a formula A in the specification. According to the concrete microorganism self-repairing material provided by the invention, the microorganism components and the modified starch are crosslinked to prepare the microorganism starch microspheres, and then the microorganism starch microspheres are compounded with the water-absorbent resin, the silicon dioxide, the calcium oxide and the calcium phosphate to prepare the concrete microorganism self-repairing material, moreover, the high-temperature resistance and anti-permeability of the self-repairing material can be improved, so that the concrete microorganism self-repairing material can permanently and stably play a repairing role in concrete, and the service life of the concrete material is prolonged. # imgabs0 #
本发明公开了一种混凝土微生物自修复材料及其制备方法，其包含微生物淀粉微球、吸水树脂、二氧化硅、氧化钙和磷酸钙；所述微生物淀粉微球通过微生物成分与改性淀粉交联制得；所述改性淀粉通过硅烯磷酯与淀粉进行接枝反应制得；所述硅烯磷酯具有如下式A所示结构。本发明提供的混凝土微生物自修复材料，通过将微生物成分与改性淀粉交联制得微生物淀粉微球后复合吸水树脂、二氧化硅、氧化钙和磷酸钙制得，其中的微生物淀粉微球不但可以包覆微生物成分提高其在混凝土中的相容性和稳定性，并且可以提高自修复材料的耐高温能力和抗渗能力，使混凝土微生物自修复材料可以持久、稳定地在混凝土中发挥修复作用，提高混凝土材料使用寿命。#imgabs0#
