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 true mineral varnish coating and multicolor finish at present, and multicolor finish is imitated with its distinctive decorative pattern True effect is the most true to nature.True mineral varnish is formed by natural colour sand allotment, and natural color placer is the most exhausted, and the prospect of true mineral varnish may Melancholy.Multicolor finish, based on synthetic emulsion, does not relies on color sand, has sustainability, 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, ornamental poor, in civil engineering, application is the strongest.Reflective insulation technology is combined with multicolor finish, is to improve Building external wall energy-saving and an ornamental important technology are broken through.
Chinese invention patent application CN 104151979 A discloses a kind of water-water reflective insulation multicolor finish, by adding Adding 2 ~ the reflective insulation powder of 30% gross weight realizes reflective insulation effect, and reflective insulation powder is rutile titanium dioxide powder body, Expensive, it is unfavorable for a large amount of uses of product.
Chinese invention patent application CN 104804601 A discloses a kind of high-performance heat-insulation and heat-preservation multicolor finish, in dispersion Basic colored paint adds the cenosphere of gross weight 10-15% mutually, makes color some granule and have reflective insulation effect, and coloured silk puts granule The coverage rate on surface is only 30%-80%, is not enough to cover whole metope, cause reflective insulation effect to decline, affect product Energy.
Summary of the invention
Problem to be solved by this invention is the deficiency overcoming prior art to exist, it is provided that a kind of reflective insulation multicolor finish And preparation method thereof.
Multicolor finish of the present invention can carry out reflective insulation to sunlight, thus reaches to save energy consumption of air conditioning system in buildings Function.Similar reflective insulation liquid granite polychrome finish only have the color some granule that dispersion phase base paint makes have reflection every Hot merit energy, and color some granule is only 30%-80% to the coverage rate on surface, causes reflective insulation effect to decline.The present invention contrasts same The one of class reflective insulation multicolor finish is big, and strategic structural point is: initiative adding in continuous phase varnish has reflective insulation effect The glass microballoon of fruit, makes whole polychrome finish all have reflective insulation function, thus improves energy-saving effect.
Tests prove that, in dispersion phase base paint, when the addition of hollow glass micro-ball reaches 8%, gained coating begins with More significantly reflective insulation effect, along with addition rises reflective insulation effect promoting, when dosage reaches 15% or more, instead Penetrate effect of heat insulation lifting trend to start to slow down.Integrated cost factor and reflective insulation effect, hollow glass micro-ball optimum addition At 8%-15%.
The present invention uses deionized water rather than general industrial tap water or subsoil water, described dispersion phase base paint, In protection colloidal sol and continuous phase varnish deionized water be through the specialty water that processed of equipment of De-ionized Water.Protecting colloid salt Being the mixture with lithium magnesium silicate as main component, lithium magnesium silicate is swelling but will not dissolve in water, water and during gradually Peel off the charged thin slice of slabbing, lamella aspect enrichment negative charge, the end face enrichment positive charge of lamella, in water disperse water and After, gradually forming " card room " structure, i.e. lamella aspect is connected with end face.Layered electronic can be with the hydroxyl second in dispersion phase base paint Functional groups on base cellulose, forms the protecting film of one layer of water resistant, makes the dispersion phase base paint colour TV granule of shades of colour Will not mutual colour mixture.Rich in multivalent ions such as the divalent calcium ions of positively charged, divalent magnesium ions in tap water or subsoil water, band The multivalent ion of positive electricity can adsorb the protecting colloid salt thin slice with negative electricity, destroys " card room " structure and above-mentioned water resistant protecting film. Therefore, the present invention uses the deionized water of the multivalent ion without positively charged.
What the present invention was initiative adds reflective insulation material, the most perfect multicolor finish in multicolor finish continuous phase Reflective insulation performance.Tests prove that, when the dosage of continuous phase hollow core glass microsphere reaches 3%, to coating reflective insulation Can there is more apparent lifting.Along with the increase of hollow glass micro-ball dosage, the reflective insulation performance of coating promotes the most therewith.But it is hollow The lifting of glass microsphere dosage also brings following several respects counter productive: a simultaneously, affects coating transparency, has influence on final dress Decorations effect;B, make dope viscosity too high, affect application property;C, hollow glass micro-ball proportion less than water, easily float, dosage mistake It is unstable that height is easily caused system, and microsphere floats, agglomerate caking;The raising of d, hollow glass micro-ball will result directly in coating PVC and improves, Too high PVC will cause strength of coating, weatherability to decline.E, cost increase.Comprehensive above pros and cons, tests prove that, continuous phase The dosage of hollow core glass microsphere is optimum addition between 3%-5%.Easily float for above-mentioned hollow glass micro-ball, agglomerate is tied The problem of block, the present invention is selected alkali swelling type thickening agent and hydroxyethyl cellulose, as the thickening agent of coating system, solve The problem of anti-settling anti-floating.
