Abstract
The present invention relates to a kind of synthetic resin emulsion of preparing building adhesive and preparation method thereof that is used to.The present invention is vinylbenzene-butyl acrylate-vinyl cyanide-acrylic acid quarternary copolymerized system, and it uses core-shell emulsion synthetic theory, substitutes segmentation and adds monomeric mode, makes institute's synthetic emulsion particle have the non-homogeneous structure of stone soft shell.Therefore, solved the contradiction of simple copolymer emulsion film-forming properties and bonding strength preferably.The easy film forming of product emulsion, intensity height after the film forming, adhesive power is strong, anti-ly stains, anti-solvent, and good with the color stuffing consistency, this emulsion is mainly used in the preparation building adhesive, is widely used in the stickup plastic floor, finishing material such as wood block floor, ceramic tile.
Description
The present invention relates to a kind of synthetic resin emulsion of preparing building adhesive and preparation method thereof that is used to.
At present, the synthetic resin emulsion that is used to prepare building adhesive mostly is a ternary copolymerization system, and available simple copolymerization realizes that the latex particle of gained is a homogeneous.The simple prepared emulsion of copolymerization exists the contradiction of the intensity after film-forming properties and the film forming.In addition, " research of quaternary acrylate copolymer emulsion and film properties thereof " literary composition of " coating process " magazine in May, 1988 publication is studied at acrylate-vinylbenzene-vinyl acetate between to for plastic-vinylformic acid, owing to contain relatively large vinyl acetate between to for plastic in the system, the products therefrom cost is low, but wetting ability and chance alkali saponified reason owing to Vinyl Acetate Copolymer, its poor water resistance, when using on cement face that is being alkalescence or the concrete surface, its water tolerance is poorer.And above-mentioned quadripolymer latex is to adopt the method for seeding polymerization to prepare.Therefore, the internal structure of emulsion particle is a uniformity in the system.
The objective of the invention is at above-mentioned shortcoming of the prior art, and a kind of quaternary phenylpropyl water-soluble emulsion and synthetic method thereof with stone soft shell structure is provided, it has solved the film-forming properties of simple copolymer emulsion and the contradiction of bonding strength preferably.
The present invention be achieved in that it be the blending theory of core-shell emulsion be applied in the base-material of building adhesive synthetic on.The present invention be styrene-propene acid butyl ester-propylene fine-acrylic acid quarternary copolymerized system, and adopt segmentation to add monomeric mode, make the emulsion particle of contained one-tenth become the non-homogeneous structure of stone soft shell.
It is specifically composed as follows:
According to the processing step requirement, it is made up of emulsifying agent, initiator, nuclear monomer, four groups of components of shell monomer, its respectively the composition and the proportioning of component be:
The first, emulsifying agent
Anionic emulsifier (by 100% content): the 0.6-1.4%(weight percent)
Nonionic emulsifier: 0.2-0.6%
Deionized water: 40-50%
The second, initiator:
Persulphate: 0.1-0.4%
Deionized water: 10-20%
Three, nuclear monomer:
Vinylbenzene: 3-8%
Butyl acrylate: 3-8%
Four, shell monomer:
Vinylbenzene: 3-10%
Butyl acrylate: 12-25%
Propylene is fine: 0.5-5%
Vinylformic acid: 0.5-3%
Above-mentioned anionic emulsifier can be chosen ms-1 or sodium lauryl sulphate.Nonionic emulsifier can be chosen op-10 or os-15.Above-mentioned persulphate can be chosen ammonium persulphate or Potassium Persulphate.
The processing step of synthetic quaternary phenylpropyl water-soluble emulsion is as follows:
The first, at first prepare respectively by above-mentioned prescription and respectively organize component solution.
The second, emulsifier solution is added in the reactor, and begin to stir, be warming up to 80-86 ℃.
Three, the formation of emulsion particle daughter nucleus:
Drip initiator solution and nuclear monomer solution in reactor simultaneously, controlled temperature is at 80-86 ℃, and control nuclear monomer solution added in 1-1.5 hour.Make system produce stable emulsion particle daughter nucleus.
Four, the formation of nucleocapsid:
Continuation drips initiator solution in reactor, and drips shell monomer solution, and controlled temperature is at 82-86 ℃, and control initiator solution and shell monomer solution add inter-sync in 2-2.5 hour.Make and carry out the lid layer soft shell on the surface of the emulsion particle daughter nucleus that in said process, forms.
Five, insulation: 82-86 ℃ of insulation 1.5 hours.
Six, be cooled to below 50 ℃, and stop to stir, use 60 order net filtration dischargings then.
Adding acrylic acid effect in the system is to make system stable, and possesses alkali thickening.Adding propylene fine is to have solvent resistance after making emulsion film forming.Because vinylformic acid and the fine possess hydrophilic property of propylene, be aggregated on the surface of emulsion particle daughter nucleus and carry out, so only becoming the shell phase to add this two kinds of monomers.
The present invention can be furnished with the dropping materials device, and reflux exchanger, temperature are taken into account on the reactor of agitator and implemented, and reactor has chuck, can be with hot water boiler or steam boiler heat supply, and with cooling water circulation from the beginning.Reactor adopts the insulation measure, and the whipped form of reactor is anchor formula or anchor frame, and mixing speed is controlled at 50-90 rev/min.
With above-mentioned prescription and technology synthetic emulsion, polymerization system is stable, and viscosity changes little, easily control.The easy film forming of product emulsion, intensity height after the film forming has stronger adhesive power, anti-ly stains, anti-solvent, and good with the color stuffing consistency, fusion is easy, and it is big that emulsion is eaten the ash amount, and cost is lower.
