Problems solved by technology

[0002] The water-based styrene-butadiene waterproof mortar emulsion on the existing market has good water and alkali resistance and rigidity, but poor flexibility. The acrylic waterproof mortar emulsion has slightly water and alkali resistance and rigidity. Worse than styrene-butadiene emulsion, but better flexibility; market polarization is serious, styrene-butadiene waterproof mortar emulsion pursues better hydrophobic effect, far exceeding the national standard in bonding strength, flexural and compressive strength, but ignores flexibility; Due to the structural characteristics of acrylic acid, it is difficult to improve the balance between flexibility and rigidity, and its bond strength and flexural compressive strength cannot reach the level of styrene-butadiene

Abstract

The invention discloses a butylbenzene modified zero-ammonia acrylic acid waterproof mortar emulsion and a preparation method thereof, and waterproof mortar. The waterproof mortar emulsion comprises 100 parts of deionized water, 25-35 parts of styrene, 50-60 parts of butyl acrylate, 1-5 parts of hydroxyethyl acrylate, 1-3 parts of hydroxyethyl methacrylate, 0.5-3 parts of methacrylic acid, 0.1-0.5part of allyl methacrylate, 0.1-0.5 part of a silane coupling agent, 55-65 parts of a styrene-butadiene emulsion, 1-10 parts of an emulsifier, 0.1-1 part of an initiator and 0.1-2 parts of sodium hydroxide. The waterproof mortar emulsion has excellent bonding strength and flexural and compressive strength, is ammonia-free and low-odor, and has good flexibility; and the preparation method is simple in process, high in controllability, low in equipment requirements and low in cost.

Description

technical field [0001] The invention relates to the emulsion and its preparation technology and the field of mortar proof, in particular to a styrene-butadiene-modified zero-ammonia acrylic acid waterproof mortar emulsion, a preparation method thereof and the waterproof mortar. Background technique [0002] The water-based styrene-butadiene waterproof mortar emulsion on the existing market has good water and alkali resistance and rigidity, but poor flexibility. Acrylic waterproof mortar emulsion is slightly worse in water and alkali resistance and rigidity than styrene-butadiene emulsion, but its flexibility is better; the market is polarized Seriously, the styrene-butadiene waterproof mortar emulsion pursues a better hydrophobic effect, which far exceeds the national standard's bond strength, flexural and compressive strength, but ignores flexibility; The balance of rigidity and strength is difficult to improve, and its bond strength and flexural compressive strength are di...
