Magnesium-calcium series anti-crack agent, preparation method thereof and waterproof cement mortar
The invention discloses a magnesium-calcium series anti-crack agent, a preparation method thereof and waterproof cement mortar. The anti-crack agent comprises a mixture formed by magnesium oxide and calcium oxide to which graphene oxide is attached. The preparation method comprises the following steps: (1) fully mixing magnesium oxide and calcium oxide to obtain magnesium-calcium powder, and then fluidizing the powder; and (2) a dispersion liquid formed by atomized graphene oxide and a volatile non-aqueous dispersion medium is applied to the fluidized powder. And mechanically grinding the obtained mixture to obtain the magnesium-calcium series anti-crack agent. The waterproof cement mortar is prepared from the following raw materials in parts by weight: 100 parts of a cementing material, 2 to 10 parts of the magnesium-calcium series anti-crack agent disclosed by the invention, 120 to 350 parts of fine aggregate and 30 to 60 parts of mixing water. The anti-crack agent effectively realizes real-time compensation of the internal volume change of the cement mortar, prevents micro-crack development, and realizes efficient water resistance of the cement mortar.
本发明公开一种镁钙系防缝剂及其制备方法与防水水泥砂浆。所述防缝剂包括附着有氧化石墨烯的氧化镁、氧化钙形成的混合物。所述制备方法包括步骤：（1）将氧化镁、氧化钙充分混合得到镁钙系粉料，然后将该粉料流态化。（2）在所述流态化的粉料中施加雾化的氧化石墨烯和易挥发的非水分散介质形成的分散液。完成后将得到的混合物进行机械研磨，完成后得所述镁钙系防缝剂。所述防水水泥砂浆，包括如下原料：胶凝材料100重量份、本发明的所述镁钙系防缝剂2~10重量份、细骨料120~350重量份、拌和水30~60重量份。所述防缝剂有效实现了水泥砂浆内部体积变化的实时补偿，预防微裂纹发展，实现水泥砂浆的高效防水。
