Description
Technical field
The present invention relates to a kind of aluminium foil, particularly relate to hydrophilic aluminium foil of a kind of organic inorganic hybridized paint and preparation method thereof and the application in air-conditioning, belong to organic-inorganic hybrid nanometer technical field of function materials.
Background technology
Hydrophilic aluminium foil is the main raw material of heat exchanger fin in conditioner, is widely used in domestic air conditioning, refrigerator, the refrigeration equipments such as automative air conditioning.GB GB/T3880 ?in 2006 specific thickness be called aluminium foil at the aluminium flake of below 0.2mm, hydrophilic aluminium foil carries out hydrophilic treatment to base material aluminium foil by special process, at its surface-coated one deck hydrophilic coating.Water of condensation can rapid drawout on hydrophilic aluminium foil, can not condense into the globule, thus increases heat exchange area, accelerates cooling and warming speed, can also effectively avoid water of condensation to hinder air flowing and the noise that produces.Hydrophilic aluminium foil is the main raw material(s) of domestic air conditioning heat exchanger fin, has extreme influence to the efficiency of conditioner.Compared with common blank aluminium foil, there is following advantage: can preservative property be increased, mould proof, the function of free from extraneous odour; The water of condensation of heat exchanger fin accumulating surfaces is evenly distributed on the surface, causes the gathering between heat exchanger fin to block, affect heat exchange conditions, thus improve rate of heat exchange 5% because of the globule after can not being formed; Because water is without pearl, the corresponding noise decreasing vibrations and cause; Conditioner oxide powder can be prevented to be blown into indoor have a negative impact to human body, meet environmental requirement; Hydrophilic aluminium foil used for air conditioner radiation fin should meet YS/T95.2 ?2001 regulation.
Prepare hydrophilic aluminium foil ubiquity at present because the consistency on hydrophilic polymer and aluminium flake surface is poor, and the problem causing the sticking power of hydrophilic coating poor.Publication number CN101942259A discloses a kind of bottom surface unified hydrophilic aluminum foil coating, by epoxy resin, vinylformic acid and urethane, by precrosslink, becomes a kind of single component coating material.By this paint on base material aluminium foil, 180 DEG C time, epoxy resin reacts prior to urethane crosslinks, forms the priming paint that one deck has corrosion resistance nature; 230 DEG C time, acrylic resin and urethane crosslinks are solidified, and form the finish paint that one deck has water-wet behavior, thus reduce by an application and once toast, enhance productivity and reduce facility investment and energy consumption.This technique solidification value is higher, and energy consumption is large.But do not adopt silane coupling agent to carry out pre-treatment, because the consistency of organic materials and metallic inorganic materials is poor, cause hydrophilic coating poor at the sticking power of aluminium foil surface.And this patent application does not carry out inorganic hydrophilic nanoparticle doped, do not investigate the planarization on the surface of film to hydrophilic impact.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of environmental protection, the surface of film defines micro-nano coarse structure, wetting ability is fabulous, the contact angle of water only 0 ?5 °, hydrophilic coating sticking power is fabulous, reach 0 ?the hydrophilic aluminium foil and preparation method thereof of organic inorganic hybridized paint of 1 grade.
Another object of the present invention is to provide the application of the hydrophilic aluminium foil of described organic inorganic hybridized paint in air-conditioning.
Hydrophilic aluminium foil of the present invention, using aluminium flake as base material, after polishing and clean, applies hydrophilic aluminum foil paint formation hydrophilic coating thereon and obtains hydrophilic aluminium foil.Hydrophilic aluminium foil surface has micro-nano coarse structure, in atmosphere to the contact angle of water be 0 ?5 °, the sticking power of hydrophilic coating be 0 ?1 grade.
The present invention carries out inorganic doping with inorganic nano hydrocolloid particle, thus can improve the wetting ability on the surface of film further.Wenzel revises YoungShi equation, obtains Wenzel equation, i.e. cos θ
w=rcos θ, in formula, r is the Rough factor of solid surface, for real surface amasss the ratio long-pending with apparent surface.Known by Wenzel equation, hydrophilic film will be more hydrophilic after increase roughness, and hydrophobic membrane is then more hydrophobic.In addition, the pretreating reagent of the present invention using silane coupling agent as hydrophilic aluminium foil surface, plays function served as bridge, thus enhances the sticking power of hydrophilic coating at aluminium foil surface.Silane coupling agent is the material that a class has special construction, itself is equivalent to an organic inorganic hybridization molecule, and at molecular chain two ends all with active group, molecular structure is: Y-Si-X
3, X is alkoxy grp, can be hydrolyzed the silicone hydroxyl forming polarity, is adsorbed in metallic substrate surface and reacts with it; Y is the another kind of active group compared with long-chain, as organic groups such as amino, epoxy group(ing), acryloxies, can react with the active group in organic coating system.Such silane coupling agent just can form one and be connected tie between coating with metal base, improves the sticking power of coating and base material.
The object of the invention is achieved through the following technical solutions:
A preparation method for the hydrophilic aluminium foil of organic inorganic hybridized paint, comprises the steps:
1) by alcohol and water in mass ratio 1:5 ?5:1 be mixed with solvent, by siloxanes or titanoxane and described solvent in mass ratio 1:1 ?1:5 be mixed in 20 ?80 DEG C of waters bath with thermostatic control, after stirring, drip catalyzer, insulation, namely obtains Nano sol; Described siloxanes or titanoxane are tetraethoxysilane, tetramethoxy-silicane and purity titanium tetraethoxide; Described alcohol is the one in ethanol, propyl alcohol, Virahol, propyl carbinol, sec-butyl alcohol and isopropylcarbinol; Described catalyzer is hydrochloric acid, nitric acid, boric acid, sulfuric acid, ammoniacal liquor, sodium bicarbonate or sodium hydroxide;
