Description
Technical field
The present invention relates to background color coating, colorful environmental protection coating material of anti-water-white being particularly used for exterior wall and preparation method thereof.
Background technology
Multicolor finish is by continuous phase or claims disperse medium, and dispersion phase composition, continuous phase low concentration, low viscosity；Dispersion phase is high concentration then, high viscosity, and containing coloring pigment.Under stirring, the dispersion phase of different colours is dispersed to respectively in continuous phase and forms macroscopic tiny grain bar or grain drips, and then mixes.Also disposable the pigmented base of different colours can be distributed in medium and form multicolor finish.According to biphase character.Multicolor finish can be divided into four classes: oil-in-water type, water-in-oil type, oil oil-in and water-in-water type.Water-in-water type and water paint, this be in aqueous latex paint add can gelation water soluble paint dispersion form.Water type multicolor paint for water drum, is actually a kind of droplet with water emulsion coating and is constituted the dispersion phase of coating, and protection glue solution constitutes the heterogeneous suspended substance of continuous phase.Obtain uniform, stable this suspended substance, be necessary for carrying out that water emulsion coating is added drop-wise to this process in protection glue solution.Do not occur the protection glue solution dilution to water emulsion coating, the condensation of latex paint and pigment to infiltration in protection sol solution etc. in this course simultaneously.Water type multicolor paint for water drum is to have the dispersing droplets of former latex paint proportioning thing wherein, forms protection glue solution continuous phase and is wrapped in the suspended substance of latex paint droplet.Realize the suspended substance of this " water-water "; it is necessary for asking in wink in water emulsion coating being scattered in protection glue solution; one layer of water-fast flexible membrane is formed on the surface being coated with gob; this layer of flexible membrane is except can outside the protection glue component except block film inside courtyard component and film spreads mutually, also prevent from assembling between Paint Drip, condensing.After spraying application, at first the gob that is coated with in wet film still protects the suspended state in aqueous phase, along with the volatilization of moisture in film, is coated with gob and mutually piles up, merges, ultimately form firmly multi-color decorative pattern film.
Patent application 201210178825.3 discloses a kind of water-soluble colorful coating and preparation method thereof.Described water-soluble colorful coating, including dispersion phase and continuous phase, wherein, described dispersion phase includes waterborne film-forming thing, pigment and water；Described continuous phase includes waterborne film-forming material, protection glue and water.This coating coloured silk point is moderate, the pattern effect of different pattern different colours can be obtained by change background color or mould, and processing technology is simple, can extensively replace wallpaper, also can be sprayed on the objects such as body of wall, wood furniture, metal, plastics and form floral designs, reach decorative effect.
But multicolor finish is along with the maturation of technology, the stability of product is become better and better, popularization and the dynamics of use in market are increasing, practice and construction in the middle of exist some problems also outstanding day by day out, after construction completes, except marmorean phase knowledge and magnanimity, it is more and more higher that to external world water-fast weather-proof also requires that, currently yet there are no about existing elongation percentage, have again water-fast, the coating of weatherability makes, as the main material of multicolor finish, the relevant report that its resistance to water-white problem is eased.
Summary of the invention
