Description
Technical field
The invention belongs to the material technology field, be specifically related to a kind of fluorocarbon art flock curtain wall board with anti-dirty and automatic cleaning function and preparation method thereof.
Background of invention
China's curtain wall development is swift and violent, faces new 21st century, and the Chinese curtain wall development of stepping into the WTO gate is that a brand-new contract is met.The coating of existing curtain wall material is mainly used fluorocarbon coating, and fluorocarbon coating has two kinds, be liquid fluorocarbon and powder fluorine carbon, and powder fluorine carbon need not use solvent, the coating utilization rate is 90-100%, hardening time is short, and therefore environmental protection, economy, efficient, energy-conservation, characteristics such as hardness is strong, operating procedure is easy are more arranged.And to make powder fluororine-carbon coating surface crude, but need possess this function of dirt-resistant self-cleaning, be the key subjects of curtain wall area research, pointed in the Tenth Five-Year Plan (2001-2005) outline: the adjustment of Industry Structure and upgrading, give prominence to new and high technology and advanced and applicable technological transformation and lifting conventional industries.At the curtain wall industry: can give prominence to the new and high technology that is applied to curtain wall at present is nanometer technology.
The basis of nanometer technology is a nano material, what wherein comparative maturity, industrialization and commercialized degree were high is: the nano material that nano particle and some traditional materials compound (hydridization) form, their application in the curtain wall field can be looked forward to as follows: nano powder can be made wear-resisting, corrosion-resistant, ageing-resistant, and has hydrophobic, oleophobic, anti-dirty automatic cleaning coating.It may be the improvement upgraded product of coatings such as current fluorine carbon, polyamine fat, electrophoresis, electrostatic powder.
Along with continually developing of nano material, the coating of utilizing the production of nanometer manufacturing development to have the dirt-resistant self-cleaning surface property is reality, makes coatings industry enter new epoch.Nano material on inlaying in coating makes coating surface present distinctive nanostructured characteristic, shows the ability of oleophobic.The performance of coating surface absorption foul mainly is because the factor of electrostatic adsorption between coating and the foul body and the intermolecular suction of the two.Here it is why the total surface of building be to adsorb foul easily and contaminated reason.
Summary of the invention
The object of the present invention is to provide a kind of fluorocarbon art hair side curtain wall panel and preparation method thereof with dirt-resistant self-cleaning function.
The fluorocarbon art hair side curtain wall panel with dirt-resistant self-cleaning function that the present invention proposes is made up of base material and the anti-soil fluororine-carbon coating that is coated on this substrate, and coating layer thickness is 30-50 μ m, and the coating constituent is as follows by weight percentage:
Mylar and fluorine resin 60-70%,
Curing agent 3-8%,
Auxiliary agent 1-4%,
Pigment 22-30%,
Dirt-resistant self-cleaning agent 1-5%,
Total amount satisfies 100%.
Wherein, polyester resin and fluorine resin are the basic film forming matter of coating.Used curing agent can be a hydroxyalkyl amide.Used auxiliary agent comprises levelling agent, degasser etc., and for example levelling agent is the acrylic compounds material, and degasser is a styrax class material.Pigment can be selected as required, as using the various pigment of carbon black, titanium white and organic or inorganic.Used dirt-resistant self-cleaning agent is a nanometer grade silica.Used base material can be metal material, plastics etc., and form can sheet material, also can be various workpiece etc.
The preparation method of above-mentioned fluorocarbon art hair side curtain wall panel is as follows:
1, base material is carried out conventional preliminary treatment.Comprise: processing such as degreasing, alkaline etching, table accent, conversion film make the surface meet the AAMA2605 standard.
2, carry out hanger, the Quality Initiative line speed is 1.5-1.6m/min.
3, the material powder of coating is mixed by aforementioned weight proportion, put into dusting device, cover lid stirs, and makes the dusty material in the efflorescence bucket of packing into enter fluidized state.
4, open the electrostatic generator switch, control air pressure is 1.5-2kg/cm
2, voltage is 75-85KV, atomization air pressure is 1.5-2kg/cm
2, powder outlet quantity is 2.7-3.2m
3/ h.
5, unlatching is stretched and is fallen machine, and the control elevator speed is 23-28m/min.
6, the control coating layer thickness is 30-50 μ M, flow time 6-8 minute.
7, enter in the baking oven and be cured, oven temperature is 230-240 ℃, and be 7-12 minute hardening time, promptly gets required high-quality dirt-resistant self-cleaning fluorine carbon curtain wall panel.
Scientific research finds that lotus leaf surface has special nanostructured, presents hydrophobic and activity oleophobic, thereby has anti-soil and self-cleaning magical function.And the coating of dirt-resistant self-cleaning is according to this phenomenon of lotus leaf, in powder fluorine carbon, add specific nano material, make to have nanostructured in the fluorocarbon coating, how obvious the crude artistic effect of the body surface after the spraying is, and water and foul are all produced stronger intermolecular repulsive force.Although Electrostatic Absorption may make coating surface adsorb fouls such as some dusts, but rainwater arrives the surface when rainy, coating is all repelled rainwater and foul, and two of rainwater and fouls have intermolecular suction, attract each other, the two breaks away from coating surface easily, the self-cleaning operation principle of dirt-resistant self-cleaning coating that Here it is.It has opened up new space for the more wide application of fluorine carbon application product.
In the fluorocarbon-sprayed curtain wall panel through the adding nano material, it has more following advantage than common fluorine carbon curtain wall panel:
(1) high temperature resistance, coating hardness is lasting:
General fluorocarbon-sprayed product coating is under outdoor 60 ° of temperature irradiation, and surface meeting deliquescing, surface micropore are expanded, and dust granule can't break away from attached to the surface, does not reach self-cleaning effect.The special sprayed coating of the present invention has the function of high temperature resistance, even more than 80 degree, can keep original hardness, avoids dust granule to invade, thereby ensures that the self-cleaning effect of exterior wall is remarkable.
(2) surface has special artistic effect:
The general fluorocarbon-sprayed this artistic hair side effect that do not reach, originally can only use polyester powder and reach this effect, surface coating quality guarantee period is 3-5, polyester powder after the silicon modification, the surface reaches 5-8 quality guarantee period, and existing the most high-quality year follows is 10 years, and the special spraying raw material of nanometer of the present invention, the surface has not only reached the performance requirement of fluorocarbon coating, but also has reached the appearance of polyester powder.Complete set has suffered both advantages, can show different artistic effects arbitrarily according to designer and proprietor's requirement, cross-linking reaction can take place and form space network in its surface coating in solidification process, reach 20 years quality guarantee period, reach 25 years even, examination criteria reaches every requirement of international AAMA2605 fully.Per time limit increase quality guarantee period 1 year just increases very requirement to its raw material and spraying coating process.
Compare with other like product, outward appearance of the present invention have break through traditional visual angle, hardness height, be difficult for scratch, aberration is little, anti-dirty self-cleaning, produce advantage such as control easily.
