The invention relates to a curing agent and a preparation method thereof. The curing agent is prepared by takingnanoscale particle silica sol as a raw material, can effectively permeate into concrete,and is subjected to hydration reaction with free active calcium ions to form a compact and firm protective layer with a hydrophobic effect, so that the firmness, wear resistance, impermeability and efflorescence performance ofconcrete are greatly improved; the solid content of the curing agent is 40% or above, the wear resistance is larger than 0.02 g/cm < 2 >, the compressive strength is largerthan 65 MPa, and it is shown that the curing agent has excellent mechanical properties; the preparation method is simple and convenient, and has the characteristics of simple production, environmentalprotection and convenient construction.
本发明涉及一种固化剂及其制备方法，本发明的固化剂以纳米级颗粒硅溶胶为原料，能有效渗透到混凝土中，与游离的活性钙离子发生水化反应，形成致密坚固具有憎水效果的防护层，从而大幅提高混凝土的坚固、耐磨、抗渗、泛碱性能；本发明固化剂固含量为40％以上，耐磨性大于0.02g/cm2，抗压强度大于65MPa，表明本发明的固化剂具有优异的力学性能；其制备方法简单，方便，具有生产简单，绿色环保，施工方便的特点。
