Background technology
Because weather condition are changeable, the exterior wall surface of buildings usually there will be Local Cracking phenomenon, and under the effect of expanding with heat and contract with cold, crack also becomes large thereupon or reduces, and this just requires that metallic paint coating has certain elasticity and water-repellancy.
Traditional solvent-borne type fluorine carbon metal paint coating is hard, fine and close, do not have elasticity, can not effectively cover crackle, the phenomenon that metallic paint cracking, hollowing even come off becomes a common quality defect, and during the construction of solvent-borne type fluorine carbon metal paint, environmental pollution also limit more greatly its application in addition.
Existing aqueous metallic paint, due to the metallic pigment such as Cu-Zn alloy powder, aluminium powder in water, very easily there is chemical reaction and eclipsed, dimmed, lose metalluster, thickening, the tank that rises, flocculation phenomenon also of common occurrence, great problems is brought to the production of aqueous metallic paint, transport, stability in storage and application property, the elasticity of water-miscible paint coating is larger, contamination resistance and the Bao Se gloss retention of coating are poorer, and above many reasons limit the promotion and application of aqueous metallic paint.
No matter solvent-borne type or aqueous metallic paint, under sun exposure, in coating, metallic pigment temperature raises very fast, but in the coating again cannot quick heat radiating, thus causes the variable color of the accelerated deterioration of metal paint film and metallic pigment itself to fade; In summer, because the thermal insulation of metallic pigment is very poor, metallic paint can also cause the rising of room temp, increases the energy consumption that the cooling systems such as air-conditioning bring further.
Application number be 200810021665.5 Chinese patent disclose a kind of two part solvent type plastic-aluminum sheet metal imitating paint of easy construction, this coating is with fluoro-resin and gather fluorine silicon resin on a small quantity for base-material, with weather resistant isocyanic ester or biuret for solidifying agent is made, there is super-weathering resistance, the features such as guarantor's look gloss retention of super contamination resistance and excellence, but because selected fluoro-resin Lumifion302(Fu – carbon bond can up to 116Kcol/mol), poly-fluorine silicon resin B605 and solidifying agent all do not have elasticity, the metallic paint coating made is fine and close, hard, ventilation property is bad, thus splitting resistance difference and easily come off.
Application number be 200910047616.3 Chinese patent disclose a kind of thermosetting metallic paint of solvent-resisting, the solvent resistance of metallic paint is improve by adding appropriate silane coupling agent, this coating has the advantage of high tenacity, high rigidity, high-wearing feature, but need high bake (200 ~ 260 DEG C) ability film forming, and the exterior wall not being suitable for buildings uses.
Application number be 200710044183.3 Chinese patent disclose a kind of nano fluorescent elastic water soluble metal lacquer, with aqueous polyvinyl acetate emulsion and silicon sol for a kind of organic-inorganic hybrid coatings made by base-material.Silicon sol based inorganic material, its advantage is that after film forming, physicals is superior, and its shortcoming is that rigidity chaps by force, easily, and aqueous polyvinyl acetate emulsion is composite makes film forming matter, and paint film has certain toughness, but thickening behavior after easily producing, stability in storage and application property bad.
In sum, the metallic paint that a kind of good springiness is needed in market badly, splitting resistance is excellent, contamination resistance is good, protect that look gloss retention is good, suitability strong and have certain effect of heat insulation and a water-proof function is to meet decoration of exterior wall demand.
