Abstract
The present invention relates to modified acrylic ester copolymerized emulsion which is mainly composed of an alkene monomer, an emulsifier, an initiator, a PH regulator and water, wherein the emulsifier is emulsifier without alkylphenol, and comprises alkyl ether sodium succinate and alkyl polyoxyethylene ether. Simultaneously, the distribution ratios of components of the emulsion are newly regulated and improved. The copolymerized emulsion of the present invention is used for preparing latex paint for an inner and an outer walls. Because the emulsifier without alkylphenol has no harm to human bodies and endocrine systems of relevant species, the present invention conforms to the requirement of environmental protection and is worthy of popularizing. Under the new matching relation, an alkene base silane coupling agent takes part for copolymerization so that the water resistance, the wash resistance and the freeze-thaw stability of the emulsion and the bearing capacity of pigments are improved. Thereby, the using performance of the emulsion is obviously improved.
Description
Technical field
The present invention relates to the acrylate copolymer emulsion of exterior wall latex coating in a kind of being used for, process modification.
Background technology
Acrylate copolymer emulsion is mainly used in confecting inner-outer wall latex coating in the building trade.Domestic widely used this kind emulsion mainly is made up of vinyl monomer, emulsifying agent, initiator, PH conditioning agent and water at present, and wherein used emulsifying agent is octyl group nonyl phenol negatively charged ion, nonionic etc., is a kind of induced by alkyl hydroxybenzene (APE) emulsifying agent that contains.Studies show that the existence that contains the induced by alkyl hydroxybenzene emulsifying agent has certain injury effect to human body and adjacent species (as fish) endocrine system, the use of therefore existing emulsion does not meet environmental requirement, has set about restriction abroad.In addition, the proportioning of each composition is unreasonable in the existing emulsion, and polymkeric substance inner particles structure bonding force is not strong, and ubiquity is water-fast, washable wiping and many deficiencies such as freeze-thaw stability and color stuffing supporting capacity difference, influences its use properties.
Summary of the invention
The technical problem to be solved in the present invention is the weak point that overcomes existing acrylic emulsion, and a kind of both compliance with environmental protection requirements are provided, and can improve the modified acrylic ester copolymer emulsion of use properties again.
Technical scheme of the present invention is: modified acrylic ester copolymer emulsion, mainly form by vinyl monomer, emulsifying agent, initiator, PH conditioning agent, deionized water, improvements are that described emulsifying agent is no induced by alkyl hydroxybenzene emulsifying agent, comprise alkyl oxide sodium succinate and alkyl polyoxyethylene ether, the per-cent that its content accounts for the emulsion gross weight is respectively: 0.8～1.5%, 0.5～1.5%; The weight percent of all the other compositions is respectively in the emulsion:
Vinyl monomer: vinylbenzene 5～25%, methyl methacrylate 2～16%, butyl acrylate 8～25%, the vinylformic acid diethyl is ester 5～12%, vinylformic acid 0.3～1%, acrylamide 0.3～0.8%, vinyltrimethoxy silane 0.1～0.3%, r-methacryloxy Trimethoxy silane 0.1～0.3%;
Initiator: ammonium persulphate 0.05～0.5%;
PH conditioning agent: sodium bicarbonate 0.05～0.08%;
Deionized water: 43～53%.
Above-mentioned no induced by alkyl hydroxybenzene emulsifying agent also comprises one or more in polyoxyethylene polyoxypropylene block polymer, allyl hydroxyl sulfonate, the allyl polyethenoxy ether vitriol, and the percentage score that its content accounts for the emulsion gross weight is in addition: 0.3～0.8%, 0.1～0.5%, 0.2～0.5%.
Owing to adopt no induced by alkyl hydroxybenzene emulsifying agent, such emulsifying agent does not have injury to the mankind and adjacent species endocrine system in the copolymer emulsion of the present invention, thereby makes and be worthy to be popularized the application compliance with environmental protection requirements of emulsion.Simultaneously, the present invention has done new adjustment and improvement to each composition proportion relation, under new proportion relation, thiazolinyl one type of silane coupling agent participates in copolymerization better, monomer in the vinyl monomer and the hydrogen bond that is adsorbed lip-deep water molecules formation covalency system, itself and adsorption layer intensive are coupled together, water-fast, washable wiping is significantly improved; The three-dimensional net structure that forms helps the more pigment particles of carrying, strengthens the adsorption type combination, and freeze thaw stability, freeze-thaw stability are better, has therefore improved the use properties of this copolymer emulsion greatly, can be used for preparing high-grade PVC latex coating.
Embodiment
Further specify component of the present invention and content (weight percent) below by embodiment:
Example one: vinylbenzene 22, methyl methacrylate 4.2, butyl acrylate 10, the vinylformic acid diethyl is ester 10, vinylformic acid 0.8, acrylamide 0.5, vinyltrimethoxy silane 0.2, r-methacryloxy Trimethoxy silane 0.2, alkyl oxide sodium succinate 1.3, alkyl polyoxyethylene ether 1, ammonium persulphate 0.45, sodium bicarbonate 0.06, deionized water 49.29.With above each component routinely technology make modified acrylic ester copolymer emulsion.
Example two: vinylbenzene 12, methyl methacrylate 12, butyl acrylate 15, the vinylformic acid diethyl is ester 6, vinylformic acid 0.5, acrylamide 0.7, vinyltrimethoxy silane 0.1, r-methacryloxy Trimethoxy silane 0.3, allyl hydroxyl sulfonate 0.3, allyl polyethenoxy ether vitriol 0.4, alkyl oxide sodium succinate 0.8, alkyl polyoxyethylene ether 1.4, ammonium persulphate 0.3, sodium bicarbonate 0.07, deionized water 50.13.With above each component routinely technology make modified acrylic ester copolymer emulsion.
