Modified water-borne epoxy resin emulsion cement mortar suitable for cold environment and preparation method of modified water-borne epoxy resin emulsion cement mortar
The invention discloses modified water-borne epoxy resin emulsion cement mortar suitable for a cold environment and a preparation method thereof, the modified water-borne epoxy resin emulsion cement mortar is composed of four components A, B, C and D. The component A is Portland cement, the component B is river sand, the component C is modified water-borne epoxy resin emulsion, and the component D is a toughening agent and a defoaming agent. The water-based epoxy emulsion is modified through the nano clay and the rubber powder, the modified water-based epoxy emulsion is used as a main additive to prepare the cement mortar suitable for the northern winter cold environment, and the cement mortar can be used in the northern winter cold environment at the temperature ranging from the normal temperature to-30 DEG C; and the high strength characteristic, the chemical stability characteristic, the cold-resistant characteristic and the like are still kept in a cold environment.
本发明公开了一种适用于寒冷环境的改性水性环氧树脂乳液水泥砂浆及其制备方法，所述改性水性环氧树脂乳液水泥砂浆由A、B、C、D四种组分组成，A组分为硅酸盐水泥，B组分为河砂，C组分改性后水性环氧树脂乳液，D组分为增韧剂及消泡剂。本发明通过纳米粘土以及橡胶粉对水性环氧乳液进行改性，并作为主要的添加剂制备出适用于北方冬季寒冷环境的水泥砂浆，所述水泥砂浆可以在常温～‑30℃北方冬季寒冷环境下使用，并在寒冷环境下仍保持较高的强度特性、化学稳定特性和耐寒特性等。
