Description
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of water type multi-color coating.
Background technology
Water-water colorful marble paint rich color is colorful, and special color can be provided on request and emulation property high, it is unrestricted in designer, can change shape arbitrarily according to the intention of Designers.The general name of the ester class of vinylformic acid and homologue thereof.Important has methyl acrylate, polyvinyl alcohol, 2-methyl methacrylate and 2-methyl polyethylene alcohol etc.Can autohemagglutination or and other monomer copolymerizations, be manufacture the monomer of tackiness agent, synthetic resins, specialty elastomer and plastics.
Multicolor finish is mainly used in copys stone material effect, so also known as liquid stone, is also local horizon exterior coating.Be made up of inconsistent two phase compositions, wherein a phase dispersion medium is external phase, and another is disperse phase mutually, during application, by disposable spray finishing, just can obtain luxurious, attractive in appearance, colorful pattern.This pattern formed by disposable spray finishing is completely different from the method being completed the multicolour pattern that could be formed by multiple working procedure successively.But along with China is more and more stricter to the protection of natural resources and national environmental protection and energy saving policy, relevant laws and regulations, make the exploitation of lithotome, processing, transportation cost constantly increase, this affects the application of lithotome in building decoration field to a certain extent.
Granite is a kind of natural stone material, belongs to magmatite, is widely used in the outdoor facing of building.But granite cost is very expensive, and have public danger at external wall as facing, not easily big area or external wall of high-rise building are shown consideration for and are established use.Therefore, in order to buildings can reach the luxurious effect of granitic outward appearance, imitated granitic material is constantly gushed out, due to granitic color many opposite sex, that imitating technology is brought is very complicated, people need a kind of imitated easy coating to simplify the complicacy of imitating technology, in this context, multicolor finish arises at the historic moment.In addition, the continuous presumption principle of building energy conservation also makes the application of External Thermal Insulation Technology for External on external wall obtain penetration and promotion.And in heat insulation base layer, carrying out stone decoration technique again, its construction process relative complex, much new thermal retardation form can not get adopting.
Polyvinyl alcohol, organic compound, white plates, cotton-shaped or pulverulent solids, tasteless.Water-soluble, be insoluble to gasoline, kerosene, vegetables oil, benzene, toluene, ethylene dichloride, tetracol phenixin, acetone, vinyl acetic monomer, methyl alcohol, ethylene glycol etc.Be slightly soluble in dimethyl sulfoxide (DMSO).Polyvinyl alcohol is important industrial chemicals, for the manufacture of polyvinyl acetal, resistance to gasoline pipeline and vinylon synthon, fabric-treating agent, emulsifying agent, paper coating, tackiness agent, glue etc.After coating, due to uneven, there is dispersion and multiple color decorative pattern can be obtained, stereoscopic sensation is strong, gloss is graceful, appearance tactile impression is good relief-type coating.The characteristic such as it has acid and alkali-resistance, water-fastness, anti-pollution, wear-resisting, bonding strength is high, can be applied to plaster, cement, asbestos, brick, wood, metallic surface.Which field is does water-water multicolor finish mainly used in? its range of application that a lot of people can feel not is very wide, actually this is not so, lithotome is long at the applicating history in building decoration field, firmly getting architect and user's favor with its noble, natural, simple and unsophisticated, luxurious style, is also one of important symbol of high-end buildings external image.
Oil-in-water-type, water-in-oil-type, oily oil-in and water-in-water type four class can be divided into by its medium condition, best with water-in-oil-type package stability, and most widely used, water-in-water type environmental protection multicolor finish is being developed in practicality.The colorful marble paint of water-water is water-based coating, meet environmental requirement, non-harmful product during construction, because containing supra polymer element, construct after complete drying, have wear-resistant, wash away the characteristic changed with uviolizing, antistatic, high temperature resistant, acid rain resistant, waterproof, anti-be full of cracks, high strength, resistance to long-term multiple weather condition, property retention is constant, is easy to maintenance and cleaning, self-cleaning is excellent, multicolour once sprays, constructs easily, is a kind of excellent water tolerance, weathering resistance, a coating material.
Multicolor finish is the new decorative material for building of beautifying hotel, movie theatre, entertainment place, shop, office building, house etc.Water-water multicolor finish is a kind of series product of Environmental Protective Water-paint system, is born for meeting the building external paint market of development now.That the pigment of modified resin and the good stability obtained with High-tech Research And Development is made, full water-based, the colorful granite coating of disposable spray finishing, the color produced is more true to nature, more durable, by the granite sample that Designers provides, emulator can reach 99%, is the best product of alternative exterior wall grouan, therefore also known as liquid stone.The performance of polyvinyl alcohol rubber affects by atomic number of alkyl carbon object in its principal monomer alkyl acrylate.Rubber based on polyvinyl alcohol, oil resistant, thermotolerance are better; And the rubber based on butyl acrylate, because atomic number of alkyl carbon object increases, the shielding effect of ester group polar group is increased, therefore water tolerance is made to make moderate progress, simultaneously due to shielding effect, reduce power between rubber molecule, increase inner plasticity, thus temperature limit of brittleness is reduced, winter hardiness is better.If by above-mentioned two kinds of monomers and use, then can obtain the rubber between both performances.
Domestic PVA consumption 51.2 ten thousand t in 2007,2000-2007 average growth rate per annum reaches 7.2%.Within 2008, affect by global financial crisis, the industry developments such as PVA downstream building, weaving seriously baffle, and domestic PVA consumption falls 4.5% on a year-on-year basis.The second half year in 2009, PVA Downstream Market took a turn for the better to some extent, and domestic PVA consumption rises 2.7% on year-on-year basis.A few years from now on, domestic PVA demand will with more stable speed increment, and consulting prediction consumption in 2015 is opened up in sky will reach 72.8 ten thousand t, 2009-2015 average growth rate per annum 6.4%.Multicolor finish is mixed into the two or more different colours of liquid or gel, size and different band look particulate in basic coating, the suspended dispersion coating of a kind of compound of composition.Water-water multicolor finish is a kind of series product of Environmental Protective Water-paint system, is born for meeting the building external paint market of development now.That the pigment of modified resin and the good stability obtained with High-tech Research And Development is made, full water-based, the colorful granite coating of disposable spray finishing, the color produced is more true to nature, more durable, by the granite sample that Designers provides, emulator can reach 99%, is the best product of alternative exterior wall grouan.
