Problems solved by technology

[0003] The technical formula of the existing waterproof coating, firstly, the selected main materials are mostly polymer emulsions emulsified by surfactants, and secondly, more plasticizers, dispersants and various surfactants are added to meet the elasticity, leveling, Viscosity, stability, brushing feel and other "construction performance", and the addition of these additives is harmful to the environment and human body
At the same time, it is found in engineering applications that most rigid waterproof mortar products have some problems such as poor impermeability, high water absorption and dry shrinkage, poor anti-aging ability and easy cracking.

Abstract

The invention discloses a double-component polymer-cement-base waterproof mortar and a preparation method thereof. The mortar comprises a liquid component and a powder component in a ratio of 1:(3.0-4.0). The liquid component comprises a VAE (vinyl acetate-ethylene) emulsion, a preservative, a defoaming agent and tap water. The powder component comprises Portland cement, quartz powder, fly ash, heavy calcium carbonate, talcum powder, modified bentonite, cellulose ether, a defoaming agent, a water reducing agent and a water repellent. The preparation method comprises the following step: mixing and stirring the liquid component and powder component. The double-component polymer-cement-base waterproof mortar has excellent physical and mechanical properties, does not do harm to the environment and human body, has excellent bending resistance, compression resistance and other physical properties, and is widely used in engineering buildings with high structural rigidity and low building deformation.

Description

technical field [0001] The invention relates to a mortar, in particular to a two-component polymer cement-based waterproof mortar and a preparation method thereof. Background technique [0002] Polymer Modified Cement Mortar For Waterproof, referred to as JF waterproof mortar, is mainly composed of cement and fine aggregate, with polymer emulsion or redispersible latex powder as modifier, and mixed with appropriate amount of additives Made of waterproof mortar. A kind of cement mortar waterproof material with certain impermeability is prepared by adjusting the mix ratio, reducing the porosity, and increasing the compactness of the interfaces of various raw materials. The two-component polymer cement-based waterproof mortar firmly bonds the ion-stabilized polymer emulsion and the cement-based aggregate produced by cement hydration into a network-like solid whole, which combines the rigid waterproof of the mortar and the flexibility and crack resistance of the polymer. The a...
