According to the invention, a pulling method is adapted to coat; the antireflection rate of a double-sided coating is about 5%; the antireflection rate of a single-sided coating is about 2.5%; the adhesive force between the film and the glass is good; no demoulding phenomenon exists; the stability of the antireflection liquid is good; the antireflection liquid does not volatilize hardly, and the yield of glass coating can be effectively improved.
Description
Technical field
The invention belongs to the anti-reflection liquid of photovoltaic industry AR glass preparation, relate in particular to the anti-reflection liquid of water-based AR glass.
Background technology
The anti-reflection film of AR glass, also referred to as antireflective coating, is according to electromagnetic theory, by film, is to adjust path difference, makes the reflected light of a certain wavelength just in time produce interference, thereby reaches the object of high transmission.Current anti-reflection liquid alcohol system more, the anti-reflection liquid of alcohol system is unstable, needs constantly supply auxiliary agent when producing continuously, the more difficult control of production process, the production efficiency of product and yield rate are all lower.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the object of this invention is to provide the anti-reflection liquid that a kind of rolling method is prepared AR glass, it can keep the anti-reflection rate of AR glass more than 2% in rolling method.
Technical scheme: for achieving the above object, the present invention by the following technical solutions: a kind of water-based is anti-reflection liquid, each component and the volume percent thereof that comprise are as follows:
Silicon sol 12%～20%;
Aluminium colloidal sol 10%～15%;
PVP-k30 1%～3%；
KH-560 1%～2%；
Hexanaphthene 1%～5%;
Nitric acid 1%～3%;
Alcohols mixture 5%～10%, and the deionized water of residual content.
As preferably, described alcohols mixture be in ethanol, ethylene glycol or propyl carbinol one or more.
As preferably, described alcohols mixture is comprised of ethanol, ethylene glycol and propyl carbinol, and the volume percent that they account for anti-reflection liquid is respectively 5%, 2% and 2%.
As preferably, the granularity of described silicon sol is below 100nm.
Beneficial effect: compared with prior art, the present invention has the following advantages: adopt crystal pulling method plated film, rate that double-sided coating is anti-reflection is 5% left and right, and rate that coating single side is anti-reflection is 2.5% left and right; Sticking power between rete and glass is good, does not have stripping phenomenon; The good stability of anti-reflection liquid, almost non-volatile, can effectively improve the yield rate of glass coating.
Embodiment
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
Embodiment 1:
A composition for the anti-reflection liquid of water-based, in Table 1

By each component proportion in table, preparing anti-reflection liquid, is 20 ℃ in envrionment temperature, and humidity is less than under 60% environment ageing 2 days, and plated film also need carry out under identical temperature and humidity.After ageing, adopt crystal pulling method plated film, pull rate is 120 millimeters/min.After plated film, two-sided anti-reflection rate is 4.8%, and one side is anti-reflection is 2.4%, and the sticking power of rete is good, and hardness reaches 4H.
Embodiment 2:
A composition for the anti-reflection liquid of water-based, in Table 2
Table 2 is anti-reflection, and each component of liquid forms
| Hexanaphthene | Ethylene glycol | Propyl carbinol | KH-570 | Alcohol | PVP-k30 | Nitric acid | Silicon sol | Aluminium colloidal sol | Deionized water |
| 2% | 2% | 2% | 1% | 5 % | 2% | 1% | 15% | 10% | 60% |
By each component proportion in table, preparing anti-reflection liquid, is 20 ℃ in envrionment temperature, and humidity is less than under 60% environment ageing 2 days, and plated film also need carry out under identical temperature and humidity.After ageing, adopt crystal pulling method plated film, pull rate is 120 millimeters/min.After plated film, two-sided anti-reflection rate is 5%, and one side is anti-reflection is 2.5%, and the sticking power of rete is good, and hardness reaches 4H.
Silicon sol is the main film forming substance of this anti-reflection liquid, therefore for silicon sol require highly, its granularity need be below 100nm, silane coupling agent can be used for improving sticking power, deionized water is solvent, and other auxiliary agent is used for regulating the viscosity of anti-reflection liquid, thereby controls SiO
2the pore size distribution of film.After employing crystal pulling method plated film, the two-sided anti-reflection rate of glass reaches 5% left and right, and rate that coating single side is anti-reflection is 2.5% left and right, and sticking power is good, and possesses certain hardness.Known by embodiment 1～2, the performance of film: one side is anti-reflection 2 ~ 2.5%, sticking power is good, and hardness reaches 4H.From anti-reflection liquid itself, this is anti-reflection, and liquid is the anti-reflection liquid of water-based, and with the anti-reflection liquid phase ratio of alcohol system, volatility is very little, can steady and continuous produce, and enhances productivity and yield rate.
