Description

A kind of reflective insulation multicolor finish and preparation method thereof
Technical field
The present invention relates to a kind of exterior coating, especially a kind of reflective insulation multicolor finish and preparation method thereof.
Background technology
Exterior wall stone-like coating mainly has lacquer coating and multicolor finish at present, and multicolor finish is imitated with its distinctive decorative pattern True effect is more true to nature.Lacquer is formed by natural colour sand allotment, and natural color placer increasingly depleted, and the prospect of lacquer may Sorrow.Multicolor finish, independent of color sand, has sustainability based on synthetic emulsion, will be the pillar of following stone-like coating Property product.
Reflective heat-insulation paint is a kind of important technology that external wall reduces energy consumption, and general reflective heat-insulation paint is due to color Color single, decorative poor, application is not strong in civil engineering.Reflective insulation technology is combined with multicolor finish, is to improve Building external wall energy-saving and a decorative important technology are broken through.
104151979 A of Chinese invention patent application CN disclose a kind of water-water reflective insulation multicolor finish, by adding Add the reflective insulation powder of 2 ~ 30% gross weights to realize reflective insulation effect, and reflective insulation powder is rutile titanium dioxide powder, It is expensive, it is unfavorable for a large amount of uses of product.
104804601 A of Chinese invention patent application CN disclose a kind of high-performance heat-insulation and heat-preservation multicolor finish, scattered The cenosphere of gross weight 10-15% is mutually added in basic colored paint, color spot particle is made and possesses reflective insulation effect, and color spot particle Coverage rate to surface is only 30%-80%, is not enough to cover whole metope, causes reflective insulation effect to decline, influences product Energy.
The content of the invention
Problem to be solved by this invention is to overcome the shortcomings of the prior art, there is provided a kind of reflective insulation multicolor finish And preparation method thereof.
Multicolor finish of the present invention can carry out reflective insulation to sunlight, so as to reach saving energy consumption of air conditioning system in buildings Function.The color spot particle that similar reflective insulation liquid granite polychrome finish only has dispersed phase base paint to make possess reflection every Hot function, and color spot particle is only 30%-80% to the coverage rate on surface, causes reflective insulation effect to decline.Present invention contrast is same Big strategic structural point of class reflective insulation multicolor finish is:The initiative addition in continuous phase varnish possesses reflective insulation effect The glass microballoon of fruit, makes whole polychrome finish possess reflective insulation function, so as to improve energy-saving effect.
Tests prove that in dispersed phase base paint, when the additive amount of hollow glass micro-ball reaches 8%, gained coating is begun with More obvious reflective insulation effect, as additive amount rises reflective insulation effect promoting, when dosage reaches 15% or more, instead Heat insulation lifting trend is penetrated to start to slow down.Comprehensive cost factor and reflective insulation effect, hollow glass micro-ball optimum addition In 8%-15%.
The present invention uses deionized water rather than general industrial tap water or underground water, the dispersed phase base paint, It is by the processed water of professional equipment of De-ionized Water to protect the deionized water in colloidal sol and continuous phase varnish.Protecting colloid salt The mixture using lithium magnesium silicate as main component, lithium magnesium silicate is swollen but not dissolves in water, water and during gradually Peel off the powered thin slice of slabbing, lamella aspect enrichment negative electrical charge, the end face enrichment positive charge of lamella, in water disperse water and Afterwards, " card room " structure is gradually formed, i.e. lamella aspect is connected with end face.Layered electronic can be with the hydroxyl second in dispersed phase base paint Functional groups on base cellulose, form the protective film of one layer of water resistant, make the dispersed phase base paint colour TV particle of a variety of colors Will not mutual colour mixture.The multivalent ion such as the divalent calcium ions rich in positively charged, divalence magnesium ion, band in tap water or underground water The multivalent ion of positive electricity can adsorb the protecting colloid salt thin slice with negative electricity, destroy " card room " structure and above-mentioned water resistant protective film. Therefore, the present invention uses the deionized water of the multivalent ion without positively charged.
The present invention is initiative to add reflective insulation material, further perfect multicolor finish in multicolor finish continuous phase Reflective insulation performance.Tests prove that when the dosage of hollow glass micro-ball reaches 3% in continuous phase, to coating reflective insulation There can be more apparent lifting.With the increase of hollow glass micro-ball dosage, the reflective insulation performance of coating is also lifted therewith.It is but hollow The lifting of glass microsphere dosage also brings following several respects counter productive at the same time:A, coating transparency is influenced, influences final dress Adorn effect;B, make dope viscosity excessive, influence application property;C, the proportion of hollow glass micro-ball is smaller than water, easily floats, dosage mistake It is unstable that height easily leads to system, and microballoon floats, agglomerate caking;D, hollow glass micro-ball, which improves, will result directly in coating PVC raisings, Excessive PVC will cause strength of coating, weatherability to decline.E, cost increase.In summary pros and cons, tests prove that, continuous phase The dosage of middle hollow glass micro-ball is optimum addition between 3%-5%.Easily float for above-mentioned hollow glass micro-ball, agglomerate knot The problem of block, the selected thickener of alkali swelling type thickener and hydroxyethyl cellulose as coating system of the present invention, solves The problem of anti-settling anti-floating.
