Abstract
The invention relates to an acrylic ester waterproof paint copolymerization emulsion and a preparation method of the acrylic ester waterproof paint copolymerization emulsion. The acrylic ester waterproof paint copolymerization emulsion is characterized in that the acrylic ester waterproof paint copolymerization emulsion mainly comprises methyl methacrylate, styrene, crylic acid 2-ethyl ethyl hexyl ester, butyl acrylate, a non-ionic emulsifier, an anionic emulsifier, monohydroxyl ethyl phosphate, N,N-dimethylethanolamine, deionized water and the like. According to a paint prepared by the acrylic ester waterproof paint copolymerization emulsion, after a film of a coating is dried, a continuous coating is formed, and the coating has the characteristics of good breaking strength for ductility, excellent water resisting property and alkali resistance, convenience in construction, no environmental pollution and the like.
Description
Technical field
The present invention relates to a kind of acrylate waterproof paint copolymer emulsion and preparation method thereof, belong to chemistry painting industry protection field.
Background technology
It has good processing performance, mechanical property and physicals acrylate resin coating, uses very extensive.But present most acrylate resin coating is solvent based coating; mostly be the liquid or solid of thickness; water insoluble; and be dissolved in the organic solvents such as aromatic hydrocarbons, ketone, and organic solvent is volatile and inflammable and explosive, poisonous; environment and human body are caused very large harm; along with people are day by day urgent and strict to the requirement of environment protection, use the requirement of preventing water coating to grow to even greater heights, the acrylate resin coating water-repellancy is just used and is given birth to.
So-called aqueous epoxy resins is the method by physics or chemistry, makes Resins, epoxy be dispersed in the stable dispersion of preparing in the dispersion medium take water as external phase with the form of particulate or drop.Can be divided into water-latex type system and water-soluble system by physical property.Wherein, take Resins, epoxy as parent, free radical causes methacrylic acid, Ethyl acrylate, Butyl acrylate and vinylbenzene, graft copolymerization.Then add the ammoniacal liquor salify, make aqueous epoxy coating.This coating can not self-vulcanizing; Water-latex type system typical method is as emulsifying agent take its aggressiveness of the polynary block of polyoxyethylene glycol-Tetra hydro Phthalic anhydride-Resins, epoxy, Resins, epoxy is scattered in water and forms translucent to milky emulsion system in the mode of drop, the drop surface is for having the emulsifying agent molecule drop of wetting ability gene, inside is hydrophobic Resins, epoxy molecule, although this system technique is simple, stability of emulsion is poor; Also handlebar Resins, epoxy is dissolved in butyl glycol ether and the alcohol mixed solvent, reacts with benzaminic acid, and product neutralizes with thanomin, add water and make emulsion, and this film can not be in self-vulcanizing, application is restricted.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the objective of the invention is to provide a kind of for
Acrylate waterproof paint copolymer emulsion and preparation method thereof, it is characterized in that this acrylate waterproof paint copolymer emulsion is mainly by methyl methacrylate, vinylbenzene, vinylformic acid 2-ethyl b hexyl, butyl acrylate, nonionic emulsifier, anionic emulsifier, single hydroxyl acetophos hydrochlorate, N, the compositions such as N-dimethylethanolamine, deionized water.
By take weight part as methyl methacrylate 5~10%; Vinylbenzene 10~20%; Vinylformic acid 2-ethyl b hexyl 10~20%; Butyl acrylate 10~30%; Non-ionic type emulsion 30~40; Anionic emulsifier 5~10; Single hydroxyl acetophos hydrochlorate 2~7; N, N-dimethylethanolamine 1~3; Deionized water 40~60% forms.
Its nonionic emulsifier is the nonylphenol with 100 oxygen ethylene chain links; Its anionic emulsion is for being with 5 oxygen ethylene chain link nonylphenol phosphoric acid salt
Its preparation method is:
The amount that monomer is arranged by prescription and nonionic emulsifier, anionic emulsifier, single hydroxyl acetophos hydrochlorate, N, N-dimethylethanolamine and water carry out suction header tank after the pre-emulsification, vinylformic acid 2-ethyl b hexyl with deionized water dissolving after another header tank of suction, the two enters reactor in the mode that drips simultaneously and carries out polyreaction, temperature of reaction is controlled at 70~85 ℃, the control rate of addition drips off reaction mass in 3~3.5h, last insulation reaction 1~1.5h.Make to react completely, then cooling transfers to 7~8 with ammoniacal liquor with the emulsion pH value.Leach by filter screen, make emulsion.
Specific implementation method
(1) takes by weighing by weight methyl methacrylate 10%; Vinylbenzene 15%; Vinylformic acid 2-ethyl b hexyl 15%; Butyl acrylate 20%; Non-ionic type emulsion 35%; Anionic emulsifier 10; Single hydroxyl acetophos hydrochlorate 5%; N, N-dimethylethanolamine 2%; Non-ionic type emulsion 37%; Anionic emulsifier 8%; Single hydroxyl acetophos hydrochlorate 5%; N, N-dimethylethanolamine 2%, for subsequent use.
(2) amount that above-mentioned monomer is arranged by filling a prescription and nonionic emulsifier, anionic emulsifier, single hydroxyl acetophos hydrochlorate, N, N-dimethylethanolamine and water carry out suction header tank after the pre-emulsification, vinylformic acid 2-ethyl b hexyl with deionized water dissolving after another header tank of suction, the two enters reactor in the mode that drips simultaneously and carries out polyreaction, temperature of reaction is controlled at 70~85 ℃, the control rate of addition, reaction mass is dripped off, last insulation reaction 1~1.5h in 3~3.5h.Make to react completely, then cooling transfers to 7~8 with ammoniacal liquor with the emulsion pH value.Leach by filter screen, make emulsion.
