Abstract

The invention relates to waterproof mortar which comprises a liquid component and a powder component. The liquid component comprises the following components in parts by weight: 20 to 50 parts of styrene-acrylate copolymer emulsion; 10 to 40 parts of vinyl acetate-vinyl copolymer emulsion; 10 to 20 parts of a workability improver; 1 to 5 parts of coalescing agent; 0.3 to 0.9 part of a defoaming agent; and 15 to 60 parts of water. The powder component comprises 10 to 40 parts of ordinary Portland cement; 5 to 40 parts of aluminate cement; 5 to 17 parts of gypsum; 25 to 50 parts of glass sand; 5 to 15 parts of glass powder; 0.1 to 0.5 part of a water reducing agent; 0.05 to 0.3 part of a stabilizing agent; 0.05 to 0.5 part of a thickening time control agent; and 0.1 to 1 part of fibers. The waterproof mortar disclosed by the invention simultaneously has the properties of higher mortar cohesiveness, proper setting time, higher compression strength and breaking strength, low bleeding amount, uniform appearance, no precipitate and strong scratch resistance, and in addition, the waterproof mortar disclosed by the invention has better construction performance at different external environment temperatures.

Description

technical field [0001] The invention relates to the technical field of polymer cement-based materials, in particular to a waterproof mortar and a preparation method thereof. Background technique [0002] At present, with the development of polymer cement-based materials, polymer cement waterproof mortar has been widely used in many projects. Polymer cement waterproof mortar has strong adhesion, excellent waterproof, impermeability and crack resistance, convenient and fast construction, and flatness. Good and many other advantages, with the gradual application of various recycled materials, the research on the product formula of related polymer cement waterproof mortar is gradually deepening, but currently on the market, all kinds of polymer cement waterproof mortar using recycled materials still have compression resistance. / The problems of reduced flexural strength and viscosity, high bleeding and long setting time limit the further application of polymer cement waterproof...
