Cement additive capable of preventing cement dialysis and preparation method thereof
The invention discloses a cement additive capable of preventing cement dialysis and a preparation method of the cement additive. The cement additive comprises the following raw materials in parts by weight: 10-30 parts of a cement adhesive, 6-28 parts of waterproof performance liquid, 0.02-0.2 parts of an organic tin catalyst, 0.1-0.2 parts of a stabilizer and 0.5-3 parts of a defoaming agent. Thecement added with the additive has hydrophobicity after being cured and does not absorb moisture any more, so that the problem of water absorption of the stone can be solved fundamentally. Therefore,the problem that crystals are formed and stone is rusted, yellowed and mildewed due to the fact that alkaline substances are separated out of the surface of the stone through micropores and capillarypores in the stone after the stone absorbs water is solved.
本发明公开了一种能够防止水泥透析的水泥添加剂及其制备方法，包括以下重量份数的原料，水泥胶粘剂10‑30份，防水性能液体6‑28份，有机锡催化剂0.02‑0.2份，稳定剂0.1‑0.2份，消泡剂0.5‑3份。添加本发明的添加剂的水泥，固化后具有憎水性，不再吸收水分，可以从根源上解决石材吸水问题；从而避免了石材吸水后碱性物质经石材中的微孔、毛细孔析出石材表面形成的结晶、以及石材的锈黄、霉变的问题。
