The invention relates to a concrete anti-cracking waterproof agent and a preparation method thereof. The concrete anti-cracking waterproof agent is prepared from the following raw materials: calcium sulphoaluminate, phenolic resin, mineral fibers, a coupling agent, fly ash, silicone oil and water according to a proper proportion. The preparation method comprises the steps: firstly, heating the calcium sulphoaluminate to a certain temperature; adding the phenolic resin and the mineral fibers, performing uniform stirring, adding the coupling agent, performing stirring to react for a certain time, adding the fly ash, the silicone oil and the water, and performing stirring and mixing for reaction so as to obtain the concrete anti-cracking waterproof agent finally. The waterproof agent is usedfor concrete, shrinkage generated in the concrete hydration process is effectively reduced on the basis of not affecting the application properties of the concrete, cracks are reduced, shrinkage cracking of the concrete is prevented, and therefore the anti-cracking and waterproof performance of the concrete is greatly improved; and the anti-cracking waterproof agent can achieve the anti-cracking and waterproof effects in concrete at the same time, and the mechanical strength of the concrete is improved to a certain extent.
本发明涉及一种混凝土抗裂防水剂及其制备方法，所述混凝土抗裂防水剂通过以硫铝酸钙、酚醛树脂、矿物纤维、偶联剂、粉煤灰、硅油和水为原料并进行适当配比，制备时，先将硫铝酸钙加热到一定温度，再加入酚醛树脂和矿物纤维进行搅拌均匀，之后加入偶联剂搅拌反应一定时间后，再加入粉煤灰、硅油和水进行搅拌混合反应，最终制得混凝土抗裂防水剂，用于混凝土中，在不影响混凝土施工性能的基础上，有效减少混凝土水化过程中产生的收缩，减少裂缝发生，防止混凝土的收缩开裂，从而大大提高混凝土的抗裂防水性能；所述抗裂防水剂能够在混凝土中同时起到抗裂和防水的功效，还对混凝土的力学强度有一定提高。
