Description
Technical field
The present invention relates to solar energy heat utilization technical field, more particularly to the preparation method of solar energy reflective aluminum mirror,
The invention also provides the solar energy reflective aluminum mirrors being prepared by above-mentioned preparation method.
Background technology
Basic type material of the reflective mirror as solar energy high temperature heat utilization has compared with high reflecting rate, specific shape,
By reflecting the solar light of large area, generally can also daylight be followed to rotate, the solar energy that light is converged in small area connects
It receives on device, improves energy density by converging light, so as to which receiver and its interior media be made to be rapidly heated, reach higher temperatures
Degree facilitates and carries out high temperature heat utilization.
Reflective mirror type common at present can be divided into the focal groove type solar optically focused system of tool in form from utilizing
System, CPC condenser systems, disc type solar energy condenser system use parabola focusing-type solar energy reflective aluminum mirror and non-focusing type tower
The plane mirror that formula condenser system, linear Fresnel condenser system, point type Fresnel condenser system use either plane is micro-
Arc reflective mirror.
In terms of the base material of reflective mirror, it is generally divided into glass material, metal material and plastic material etc..Wherein glass material and
The base material cost of plastic material is relatively low.The rigidity of plastic material mirror is relatively low, and purposes is less.Glass material is with its price is low, rigidity
It is good, more it is used for solar thermal utilization occasion.The solar energy reflective aluminum mirror of mainstream is glass material at present, thickness 4mm, but
Shortcoming is high cost, heaviness, frangible, installation difficulty is big and is unfavorable for recycling.The characteristics of these shortcomings are by glass itself
It is determined.
Existing solar energy reflective aluminum mirror is primarily present following deficiency：1st, easily occur after reflective mirror brittle fracture all broken
Danger；2nd, weight is big, and unit area building cost is of high cost.
Invention content
For existing glass reflector there are the defects of, the present invention propose a kind of preparation side of solar energy reflective aluminum mirror
Method, it is at low cost, and the solar energy reflective aluminum mirror being prepared solves that glass product is heavy, frangible, installation difficulty greatly and not
The problem of conducive to recycling.
In order to solve the above technical problems, the technology of the present invention uses following technical scheme：
A kind of preparation method of solar energy reflective aluminum mirror, includes the following steps：
a：First with the surface of wet type multi- pass rolling technique aluminum volume substrate to form primary minute surface, minute surface degree is
80-85%；
b：The aluminic acid for being 17-22% with free acid concentration takes off degreasing degreasing agent and carries out degreasing degreasing processing to primary minute surface,
Processing time is 45-60 seconds；
c：Then aluminium volume substrate clear water is rinsed 35-50 seconds, is placed 40-50 seconds after the completion of rinsing, then at 130-150 DEG C
Drying and processing is carried out in temperature, obtain it is clean without aluminium powder dust and the aluminium minute surface of greasy dirt, at this time with clean blank sheet of paper towel
Wiping should can't see any spot；
d：The Polyester Paint that viscosity is 60-65 degree is coated on to the back side of aluminium volume substrate with applicator roll, using 210-230 DEG C
Temperature, the baking of 80-100 seconds time form 15-25 microns of polyester protective layer；
e：Aluminium minute surface is subjected to dry type rolling by ultraphotic mirror roller, the roughness of the mirror roller is 0.006-0.008
Micron rolls processing capacity 2-20%, and draught pressure is 20-45 tons unilateral, and passes through luminous flux instrument monitoring and controlling, so as to fulfill minute surface
Spend the level of 90-95%；Rolling processing capacity is (original thickness-finished product thickness)/original thickness, the specific starting shape for regarding blank
Depending on state；
f：Finally high transparency fluorocarbon resin coating, coating viscosity are 60-65 seconds in coating on the minute surface of formation, then
Through 210-230 DEG C of temperature, the baking of 90-110 seconds time forms 10-15 microns of fluorine carbon protective layer, with extremely strong weathering
Property, heat resistance, resistance to acid and alkali and salt fog resistance.Indices are up to or over requirements of the national standard.Wherein weatherability surpasses
Cross standard GB/T/T 1865 4000 hours can reach 6000 hours.
The high transparency Fluorocarbon resin coating simultaneously, can realize that minute surface (about 5%) in the case of limited attenuation reaches
Outdoor round-the-clock uses the target of 10 years, and both material technology technologies it is beautiful with reference to and body into product can perfection replace
For existing glass reflecting mirror board.
In Step d, this back-protective coating is very crucial, and there are two extremely important effects：First, aluminium is avoided to roll up substrate
Because the variation of tension itself makes to abrade the new aluminum particle of generation, scratch between aluminium volume substrate when being wound after the completion of step in front
Aluminium volume real estate can also destroy the surface foundation of mirror finish, and the two is all big the avoiding of aluminium volume substrate mirror finish；Two
It is to be proved by the production practices over nearly 5 years, which has the reflecting rate for improving aluminium minute surface when rolling specular aluminium
Very big help.
Polyester Paint is also unsaturated polyester varnish, and English name Polyester paint, abbreviation PE, it is a kind of multicomponent paint,
It is with a kind of polyester resin thick matter paint made of main film forming matter.The paint film of Polyester Paint is plentiful, and thickness face is hard.Polyester paint is constructed
Cured in the process, the deal of these curing agent accounts for painting total deal 1/3rd.These curing agent are also referred to as hard
Agent, main component are TDI (toluene di-isocyanate(TDI)s/toluenediisocyanate), and Polyester Paint is most common aluminium sheet
One of protective paint.
The principle of the present invention is as follows：Pre- primary coat aluminium super mirror surface is dry to roll technology, utilizes no medium roller milling roller minute surface height
The principle of reduction is highly restored to the super mirror surface of roll on aluminium sheet, realizes the superelevation minute surface degree on aluminium sheet minute surface.It is real simultaneously
Trampling proves that pre- primary coat aluminium has extremely important effect in dry roll to the raising of minute surface degree；Utilize the weather-proof guarantor of newest fluorocarbon resin
On shield technology combination ultraphotic minute surface aluminium sheet, reflecting glass minute surface is substituted so as to perfect.
The invention also provides the solar energy that a kind of preparation method according to above-mentioned solar energy reflective aluminum mirror is prepared is anti-
Light aluminium mirror rolls up substrate including aluminium and is respectively arranged on the fluorine carbon protective layer of its positive and negative and polyester protective layer.
Compared with prior art, the device have the advantages that being：
Advantage 1：The minute surface degree of specular aluminium that can be produced than the prior art improves more than 10%, so that photothermal conversion is imitated
Rate is improved close to the level for reaching glass mirror panel, implement technical means aspect：It is rolled with ultraphotic mirror roller is dry by oil removing degreasing
The primary minute surface of processing is applied to improve minute surface degree level with the back of the body, is unprecedented in industry；With reference to newest resinous protective coating layer
Protection to aluminium minute surface, to reach long-time service life 10 years outdoor.
Advantage 2：Because the material cost and process costs of the present invention are relatively low, therefore cost unit area is reduced
72%；The present invention reduces 90% relative to glassware, unit of weight area；Transportation cost reduces 90%, and installation difficulty is low；
The production loss of the present invention is reduced to by the 1-2% of glassware close to 0；Product recycle value of the present invention improve 50% with
On.
