Low-carbon high-strength building material and preparation method thereof
The invention discloses a low-carbon high-strength building material and a preparation method thereof. The preparation method comprises the following steps: mixing a liquid monomer and a coupling agent containing a double-bond functional group in proportion to obtain a monomer binder; the preparation method comprises the following steps: deoxidizing a monomer binder, adding an initiator, adding the obtained mixture into a mold filled with solid particles, uniformly mixing the materials by knocking or shaking the mold, and finally initiating in-situ polymerization to obtain the low-carbon high-strength building material. After a liquid monomer capable of forming a hydrogen bond and a coupling agent containing a double-bond functional group are combined for use, the liquid monomer can quickly infiltrate the surfaces of solid particles and enter gaps among the solid particles due to low viscosity and high flowability before in-situ polymerization, so that a self-assembly process is realized; the formed polymer not only can enhance the strength of the bonding system body, but also can enable the polymer chain to be firmly anchored on the surfaces of solid particles. The highest compressive strength of the building material prepared by the method can reach 190 MPa, which is far beyond the highest national standard of common bricks and concrete.
本发明公开一种低碳高强建筑材料及其制备方法。该制备方法包括：将液态单体和含有双键官能团的偶联剂按比例混合，得到单体粘结剂；将单体粘结剂除氧后，加入引发剂，之后将其加入到装有固体颗粒的模具中，通过敲击或震击模具的方式使各物料混合均匀，最后引发原位聚合得到低碳高强建筑材料。将可以形成氢键的液态单体与含有双键官能团的偶联剂组合使用后，使其在原位聚合前由于粘度低、流动性强可以快速浸润固体颗粒表面并进入固体颗粒间缝隙，实现自组装过程，在发生原位聚合后，形成的聚合物既能增强粘结体系本体强度，又能使聚合物链牢固锚定在固体颗粒表面。用本方法制得的建筑材料抗压强度最高可达190 MPa，远超普通砖和混凝土的最高国家标准。
