Abstract
A modified acrylate copolymer used for the emulsoid paint of internal and external walls is prepared from ene-type monomer, emulsifier without alkylphenol (such as sodium alkylether succinate and alkylpolyoxyvinylether), trigger, pH regulator and water. It can improve the performance of said emulsoid paint.
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, 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%, vinylformic acid ethylhexyl 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 per-cent that its content accounts for the emulsion gross weight is respectively: 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, vinylformic acid ethylhexyl 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, vinylformic acid ethylhexyl 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.
