A preparation method of the novel polyvinyl acetate coating comprises the following steps: uniformly mixing deionized water, polyvinyl acetate emulsion, propylene glycol, butanol, tributyl phosphate and silicone oil, adding talcum powder and quartz powder, and performing rolling to obtain the product. The emulsion coating disclosed by the invention has the characteristics of no toxicity, no irritant gas and non-inflammability; and Compared with common coatings, the emulsion coating has excellent water resistance.
Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of floor paint of polyvinyl acetate emulsion and preparation method thereof.
Background technology
Coating, is called paint in Chinese tradition name.So-called coating is coated in protected or decorated body surface; and the continuous film of firm attachment can be formed with coated article; normally based on resin or oily or emulsion; add or do not add pigment, filler; add corresponding additive, with organic solvent or the formulated thick liquid of cobalt naphthenate.Coating normally based on resin or oil, and adds or does not add face, filler, the thick liquid modulated with organic solvent or water, has also occurred with the coating new variety of solid form existence as powder coating.No matter the form (liquid or solid) of all kinds of coating coating variety, at least should be made up of two or three basal component.Namely main film forming substance is divided into; Film forming subsidiary material matter and auxiliary film forming matter.Coating can be coated on substrate surface and form the liquid or solid macromolecular material of tough and tensile continuous film (paint film).Paint finishing can bond very well with body material in body surface and form the material of complete and tough and tensile protective membrane, is called coating.Coating and paint are identical concepts.Paint is people's custom titles used for a long time, after introducing China, just utilizes in building trade always.The effect of coating may be summarized to be three aspects: provide protection, decoration function, specific function effect.The general composition of coating: comprise filmogen, color stuffing, solvent, auxiliary agent.
Coating refers to and is applied to body surface and the general name forming the material of tough and tensile protective membrane, and building coating is an important class in coating, in China, generally will be used for inner wall of building, exterior wall, ceiling, ground, and the coating of toilet is called building coating.Polyvinyl acetate emulsion, it is a kind of conventional white glue with vinyl, be mainly used in timber, decorative sheet, sheet processing, without traditional thread binding door, leather goods, wooden bonding with cement products and sticking agent etc. of printing and dyeing, easy to use, nontoxic odorless, corrosion-free piece, divide D505 type, I type, II type and type III four kinds of models, solid content 18-45%
