Abstract
The invention discloses a preparation method of vinyl acetate-vinyl versatate copolymer emulsion. The emulsion with perfect alkali resistance, water resistance and weather resistance can be prepared by modifying vinyl acetate emulsion with a vinyl versatate monomer, adopting a seeding polymerization process, taking potassium persulfate as an initiator and an anion-nonionic compound emulsifier and adding a certain amount of acrylate monomer. According to the method disclosed by the invention, goo-performance special emulsion for an external wall building coating can be obtained by adopting a vinyl acetate-vinyl versatate copolymer; and by adopting the method, the reaction in the production process is steady and easy to control while three wastes are avoided and the alkali resistance is enough.
Description
Technical field
The invention discloses the method for production of vinyl acetate and tertiary ethylene carbonate copolymer emulsion.
Background technology
The monomer such as vinyl acetate between to for plastic and tertiary ethylene carbonate forms copolymer emulsion by letex polymerization, it is the modified product of vinyl acetate, because vinyl acetate between to for plastic and tertiary ethylene carbonate belong to vinyl unsaturated monomer, polarity is substantially consistent, unexpectedly poly-rate is close, thus can form uniform multipolymer polymer in copolyreaction.
At present, domestic for the production of exterior wall latex paint mainly based on pure Class C emulsion, but it is on the high side, can reach the performance similar to pure-acrylic emulsion, and cost is lower than pure-acrylic emulsion with vinyl acetate to the emulsion of tertiary ethylene carbonate copolymerization gained.By more known, the performance of tertiary vinegar milk shellac varnish is suitable with pure-acrylic emulsion, is better than vinegar third, styrene-acrylic latex coating.
Summary of the invention
The present invention relates to the method for production of vinyl acetate and tertiary ethylene carbonate copolymer emulsion, modification is carried out with tertiary monocarboxylic acid ethene alicyclic monomer Dichlorodiphenyl Acetate ethene fat liquor, adopt the method for seeding polymerization, take Potassium Persulphate as initiator, use negatively charged ion and the composite emulsifying agent of nonionic, add a certain amount of acrylic ester monomer, the alkali resistance that can make, water tolerance, the all extraordinary emulsion of weathering resistance, production method is as follows: in still, add water, add protective colloid under agitation, emulsifying agent and other reagent, after abundant dissolving, partial monosomy and initiator are added in reactor, be heated to 76 degrees Celsius, after keeping this thermotonus 15min, remaining monomer and initiator are dripped in reactor, temperature of reaction is made to remain on 76 degrees Celsius, monomer drips off at 3h ~ 4h, insulation 1h, after having reacted, cooling filter coating material, both emulsion was obtained.
Described logical emulsifier system adopts the method for anion surfactant and nonionogenic tenside compound use, takes into account mechanical stability and the chemical stability of emulsion.
Described interpolation buffer reagent is the pH value in order to regulate reactive system, the pH value of reactive system can be maintained in certain scope, and playing the effect controlling speed of reaction, is the distribution narrow of latex granularity, improve the over-all properties of emulsion, the buffer reagent adopted in test is acetic acid and borax.
The positively effect that the present invention has is:
The outer wall building coating special emulsion that the present invention selects vinyl acetate between to for plastic one tertiary ethylene carbonate system interpolymer available energy excellent, adopts this technique, production process reacting balance, easy to control, without the three wastes, and has enough alkali resistances.
