Description
Technical Field
The invention belongs to the field of coatings, and particularly relates to a vinyl acetate-tert emulsion, a coating containing the vinyl acetate-tert emulsion, a raw material composition of the vinyl acetate-tert emulsion, a preparation method and application of the vinyl acetate-tert emulsion.
Background
The waterproof coating is widely applied to the field of buildings, is used as an inner and outer wall coating to be coated on the surface of a cement base material, and generally selects a coating with better water resistance and alkali resistance because the cement base material has stronger alkalinity. At present, the commonly used waterproof coating comprises styrene-acrylic emulsion, vinyl acetate-acrylic emulsion and the like. The styrene-acrylic emulsion has a large odor, so that requirements of part customers on low odor, excellent opening time, good workability and the like cannot be met, and the application of the styrene-acrylic emulsion is limited. Although the vinyl acetate-acrylic emulsion has the advantages of low odor, high gloss, high fullness, good can opening effect and the like, the application of the vinyl acetate-acrylic emulsion is limited due to the poor water resistance, alkali resistance and weather resistance of the vinyl acetate-acrylic emulsion.
The vinyl acetate-acrylic emulsion is an aqueous polymer resin prepared by copolymerizing vinyl acetate, an acrylate monomer and a vinyl versatate monomer serving as main raw materials, and is an upgraded variety of the traditional vinyl acetate-acrylic emulsion. Because the film forming temperature of the vinyl acetate is lower, the addition amount of the film forming auxiliary agent can be reduced, the production cost of a coating enterprise can be effectively reduced, the vinyl acetate and the vinyl versatate belong to vinyl ester unsaturated monomers, the reactivity ratios are similar, and the copolymerization reaction can be stably carried out. Vinyl versatate is grafted on a molecular chain of the vinyl versatate copolymer, and the performance of the vinyl versatate emulsion can be improved through an umbrella-shaped protection effect formed by steric hindrance of alkyl of the vinyl versatate copolymer, but the higher the addition of the vinyl versatate, the better the addition, on one hand, the higher the price of the vinyl versatate, and the lower the cost performance; on the other hand, with the increase of the dosage of the ethylene versatate, the viscosity of a paint film is increased, dust is easy to adhere, and the compactness of a formed film is reduced. At present, the vinyl acetate-tert emulsion is generally prepared by copolymerizing 70-80% of vinyl acetate and 20-30% of acrylic ester with 20-30% of vinyl versatate, and has low cost performance, so the vinyl acetate-tert emulsion is not well applied and popularized in the market.
Therefore, there is a need in the art to develop a waterproof coating material that has the advantages of high cost performance, low odor, high gloss, high fullness, water resistance, alkali resistance, weather resistance, good film-forming compactness, etc.
Disclosure of Invention
The invention aims to solve the technical problems that vinyl versatate emulsion in the prior art is poor in water resistance, alkali resistance and weather resistance, and the addition of vinyl versatate can improve the product performance, but the vinyl versatate emulsion is high in cost, and the addition of the vinyl versatate can cause the increase of viscosity and the possibility of dust, so that the vinyl versatate emulsion, the coating containing the vinyl versatate emulsion, the raw material composition containing the vinyl versatate emulsion, the preparation method and the application of the vinyl versatate emulsion are provided. The prepared vinyl versatate emulsion reduces the addition amount of vinyl versatate and reduces the cost under the condition of considering performance; the paint prepared by the method has ideal mechanical property and strong water resistance and alkali resistance.
