Abstract
The present invention discloses subdivided polymer mucilage glue and a preparation method; the manufacturing of the subdivided polymer mucilage glue is that: an acetic acid ethylene ester, cinnamene and crylic acid ester are mixed together by the aggregation of latex under the condition of additive, emulsification and solicitation; and then the polymer latex is produced; and then the method uses a spraying drying to dry the polymer latex; besides, the adhesive-proof is added into. Because adding the adhesive-proof and the additive, the subdivided polymer mucilage glue is not easy to be felted to the solid; if adding the water, the subdivided polymer mucilage glue can become the stable separated liquid; the polymer in the separated liquid not only has much better dispersing ability, but also has much higher felting intension; the method can also keep the performance for the original polymer.
Description
Technical field
The present invention relates to a kind of property-modifying additive of cement-based material, be specifically related to a kind of redispersible polymer viscose glue powder that can be used as cement-based material properties-correcting agent and preparation method thereof.
Background technology
Begin from the fifties in last century, Japan material scholar Yoshihiko Ohama is applied to polymer latex in the cement material, not only improved the folding strength of cement-based material significantly, also because the plasticizing and the bleed effect of polymer latex Ruzhong emulsifying agent, flowability of newly mixing cement-based material and the freeze-thaw resistance that hardens the back cement-based material have been improved significantly, form network structure with cement-hydrate after the polymer latex film forming, the aperture structure that has suppressed cement-based material has reduced the sepage ventilation property of cement-based material significantly.The excellent properties of polymer emulsion remodeling cement-based material has caused the great attention of the researcher of being engaged in cement material research, now the polymer latex of successful Application mainly contains polyethylene vinyl acetate ester gum breast (EVA), styrene-butadiene latex (SB) and styrene-acrylic latex etc., mainly is used as concrete repair mortar, common mending mortar, terrace mortar, self-leveling terrace mortar, wall and floor tile adhesive agent, jointing agent etc.The successful Application of polymer latex has enlarged the use range of cement-based material, and improved some performance of cement-based material significantly, but utilize polymer latex modified cement sill in use to have following problem: at first to show and use inconvenience and proportioning to be difficult to accurate control, utilize polymer latex preparation cement-based material, need buy polymer emulsion and cement-based material respectively, be mixed in proportion during use, but the solid content of polymer latex is uncertain, so the proportioning of each component is difficult to accurate control; Next is that polymer latex Ruzhong at least 50% is a water, brings many inconvenience for transportation and storage, and has increased Packing Fee.
Therefore, the premium properties that people wish have a kind of single-component system to obtain polymer mortar more easily and had, the appearance of redispersible polymer powder makes this hope become reality.Redispersible polymer powder is meant the polymer latex that obtains by letex polymerization, the polymer powder that obtains through super-dry or other means, when with it with after water mixes by a certain percentage, can form stable polymer latex once more, and have the performance of original synthetic polymer latex.
The multiple performance of cement-based material can be significantly improved at the redispersible polymer viscose glue powder end as additive, as cohesive force, impermeability etc., compare with traditional polymer emulsion modified cement material with the cement works dry powder that this class is additive agent modified, have many advantages: because the proportioning of liquid material and powder is difficult to accurate grasp, cause the difference on each batch of material performance when (1) can be avoided using; (2) easy construction is easily gone; (3) owing to be Powdered, avoided emulsion form a large amount of water made that transportation difficulty, packing are big because of having, shelf lives weak point, winter problem such as easy freezing, reduced cost.
Yet, in the process at preparation redispersible polymer viscose glue powder end, the subject matter that runs into is, should make it that redispersibility is preferably arranged in water, can not reduce the water tolerance behind the material filming again, in the prior art, the component adjustment by polymkeric substance can improve its redispersibility in water, but the problem that but can cause the water tolerance after the film forming to descend simultaneously.Another difficult point is, makes behind the powder because polymer flexibility is big, is easy to return stick into piece again.Thereby, only address the above problem, just can make the redispersible polymer viscose glue powder end obtain large-scale promotion application.
Summary of the invention
The object of the invention provides a kind of redispersible polymer viscose glue powder and preparation method thereof, in the redispersibility after raising adds water, and water tolerance and cohesive strength after the assurance film forming, and keep original synthetic polymer performance constant.
For achieving the above object, the technical solution used in the present invention is: a kind of redispersible polymer viscose glue powder, it is to carry out copolymerization by letex polymerization by vinyl acetate, vinylbenzene and acrylic ester monomer in the presence of additive, emulsifying agent and initiator, make polymer emulsion earlier, again by dry this polymer emulsion of spray-drying process, add release agent simultaneously and make, described additive is selected from potassium hydroxide or sodium hydroxide.
In the technique scheme, described acrylic ester monomer is selected from methyl acrylate, ethyl propenoate, Octyl acrylate or Isooctyl acrylate monomer.
Letex polymerization is a kind of common polymerization process, and those skilled in the art can select emulsifying agent and initiator according to comonomer.Optimized technical scheme is, described emulsifying agent is selected from a kind of in gelatin, OP emulsifying agent, the polyvinyl alcohol; Described initiator is selected from a kind of in Potassium Persulphate, the ammonium persulphate.
In the technique scheme, described release agent is selected from a kind of in white carbon black, kaolin, talcum powder or the calcium formiate.
The concrete preparation technology of this redispersible polymer viscose glue powder may further comprise the steps:
(1) gets the emulsifying agent of 3%-10% of comonomer total mass and the additive of comonomer total mass 1%-3% and be dissolved in the water, obtain component a;
(2) get the initiator of the 0.2%-1% of comonomer total mass, be dissolved in water, obtain components b;
(3) with comonomer vinyl acetate, vinylbenzene, acrylic ester monomer by mass ratio 10-30: 10-50: 30-60 mixes, and obtains mix monomer;
(4) components b and mix monomer are added among the component a that has been warming up to 70-90 ℃, react after 3-4 hour, be warming up to 90-100 ℃ of reaction 1-2 hour, cooling obtains polymer emulsion;
(5) emulsion is used the spray method drying, when spraying, added the release agent of the 10%-25% of monomer total mass, promptly obtain required redispersible polymer viscose glue powder.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
1. because the present invention adopts vinyl acetate-cinnamic acrylic ester analog copolymer, and add sodium hydroxide or potassium hydroxide as additive, adjust the relation between redispersibility and the water tolerance, make redispersible polymer viscose glue powder when having good adhesiveproperties and redispersible, curing speed is fast, has excellent water tolerance, winter hardiness after the film forming.
2. owing to added release agent, dried powder can become discrete particles and be difficult for being bonded to piece.
3. be Powdered owing to product, thereby its shelf lives is long, even if also frozen problem can not take place in the winter time; Little, the convenient transportation of the packing of product be the more important thing is easy to use.
