Problems solved by technology

[0005] However, most of the conventional polymer cement waterproof mortar is rubber powder with poor water resistance, and polymer emulsions with excellent acid and alkali resistance, blister resistance and excellent comprehensive properties are rarely used, resulting in poor acid and alkali resistance and corrosion resistance of the material. , and because the formula design is not scientific enough, the coating strength is low, and the safety of the next construction cannot be guaranteed

Abstract

Disclosed is a polymer cement waterproofing mortar comprising a liquid material component and a powder material component, wherein the liquid material component includes styrene-acrylic emulsion, a dispersing agent, an anti-corrosion agent, a defoamer and the balanced being water; and the powder material component includes ordinary Portland cement, ultrafine furnace slag, ultrafine steel slag, desulfurization gypsum, graded quartz powder, bentonite, silicon oxide, citric acid, diatomite and a water reducer. The polymer cement waterproofing mortar has excellent anti-seepage and adhesive performances, is anti-aging and acid- and alkali-resistant, can effectively consume solid wastes, is reduced in environment damage and meanwhile production cost, is wide in market prospect and can be popularized in large scope.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a polymer cement waterproof mortar. Background technique [0002] Mortar is made by mixing inorganic cementitious material with fine aggregate and water in proportion, also known as mortar. For masonry and plastering projects, it can be divided into masonry mortar and plastering mortar. The former is used for masonry and component installation of bricks, stones, blocks, etc.; the latter is used for walls, floors, roofs and beams. Plastering of the surface of the column structure, etc., to meet the requirements of protection and decoration. Some of the ordinary mortar materials are gypsum, lime plaster or clay mixed with fibrous reinforcing materials and water to prepare a paste, which is called ash, paste, mud or cement. Commonly used are hemp knife ash (lime plaster mixed with hemp knife), paper ash (lime plaster mixed with paper rebar), gypsum ash (lime plaster mixe...
