The aqueous emulsion contains ethane-vinyl acetate copolymer aqueous emulsion(A), polybasic carboxylic acid composite or polybasic carboxylic acid composite salt(B) in which one molecule has at least two carboxylic acids and amino alcohol(C), wherein the aqueous emulsion can inhibit the generation of salt efflorescence without affecting cement solidification, and is a novel aqueous emulsion for polymer concrete waterproofing agents, which is optimally applied to civil engineering and architectural fields.
Description
Technical field
The present invention relates to polymer cement is water-resisting agent use emulsion, more specifically, relate to the improvement that do not hinder cement solidification the polymer cement of generation of salt efflorescence (frosting) be water-resisting agent use emulsion.
Background technology
At building, building field, facts have proved: by mixing the water dispersion of synthetic resins in cement, sand, comparing when not adding, significantly improved physical strength and weather resistance, is water-resisting agent as polymer cement, is widely used as the water-resisting agent on balcony and roof.But contained calcium ion and airborne carbon dioxide reaction in the cement can produce the calcium carbonate that is called as salt efflorescence (frosting) by the cement surface after construction.To the inhibition that this salt efflorescence produces, insufficient under the water dispersion of existing synthetic resins, be the reason of the poor attachment of salt efflorescence when producing caused bad order and bonding surface layer paint and waterproof sheet etc.
As the method that prevents that this salt efflorescence from producing, disclosing to mixed olefins is that the mixed solution of monomer and acrylic monomer is given the method (patent documentation 1) that water tolerance, water-retentivity produce to suppress salt efflorescence.But its main application is the content of implementing in respect to the few scope of the resin content of cement, sand for being used for polymer cement mortar.Polymer cement in reality is in the common cooperation of water-resisting agent, because the amount of the polymkeric substance emulsion that uses is many, therefore, because of the various promoting agents that use in ethylene series monomer and the acrylic monomer, the impact of additive, the solidification delay of cement can occur, and the practicality aspect still has problems.
