Property, the fields such as magnetic recording, photosensitive material, electronics, electric insulation, industrial film, package decoration can be widely used in, are also suitable for
The secondary operation such as printing, paper bag.The good mechanical performance of PET film (high temperature resistance polyester film), obdurability are all thermoplasticity
Best in plastics, tensile strength and impact strength are more much higher than general film；To cater to market needs, a variety of PET films, such as
High bright film, transfer membrane, reflective membrane, chemical application film etc., are made in succession.
To further improve the optical property of PET film, using special coating technique, such as spin-coating method, czochralski method etc. will
Certain special optical materials are equably applied to PET film surface and become optical thin film, real with the science for being applied to specific demand
Test with actual production life in.

Summary of the invention
Goal of the invention: for the application demand for meeting scientific experiment and actual production life, the present invention proposes a kind of visible light
The preparation method of high transmittance film can further improve the optical property of the light-transmitting substrates such as PET film.
Technical solution: to achieve the above object, the present invention adopts the following technical scheme:
A kind of preparation method of visible light high transmittance film, comprising the following steps:
Step 1: polyvinylpyrrolidone being dissolved in water or ethylene glycol, obtains aqueous povidone solution or polyethylene
Pyrrolidones ethylene glycol solution；
Step 2: mantoquita being dissolved in water or ethylene glycol, copper salt solution or mantoquita ethylene glycol solution is made, to gained mantoquita
The resulting aqueous povidone solution of step 1 or polyvinylpyrrolidone second are added in aqueous solution or mantoquita ethylene glycol solution
Glycol solution obtains the mantoquita colloidal liquid of near-infrared light intensity absorption；
Step 3: step 2 gained mantoquita colloidal liquid being uniformly applied in light-transmitting substrate, is obtained to visible light high transmission, closely
The optical thin film of infrared light intensity absorption.

Step 2: mantoquita, including copper nitrate, copper chloride, copper sulphate, copper acetate being dissolved in water and ethylene glycol respectively, made
Obtain the identical copper salt solution of concentration and mantoquita ethylene glycol solution.
Embodiment 1: taking each portion of step 2 gained copper salt solution, and is separately added into step 1 gained PVP second two thereto
Alcoholic solution is to get mantoquita colloidal liquid, and wherein the concentration of mantoquita and PVP are 3mol/L, and the volume ratio of water and ethylene glycol is small
In 5.
Embodiment 2: each portion of step 2 gained copper salt solution is taken, and the PVP for being separately added into different volumes concentration thereto is molten
Liquid configures identical viscosity, the mantoquita colloidal liquid of different transmitances.Keep the concentration of PVP constant, the concentration of mantoquita 2~
4mol/L。
Step 3: utilizing glue spreader, the mantoquita colloidal liquid prepared in embodiment 1 and embodiment 2 is uniformly applied to light transmission
On substrate (PET film or sheet glass), visible light (wave-length coverage 350-600nm) high transmission, near-infrared light intensity absorption are prepared
Optical thin film.Using ultraviolet-visible-infrared spectrometer (UV-6300 and UV-3600) to mantoquita colloidal liquid obtained and optics
Film is tested, and transmission spectrum is drawn.
A certain amount of copper sulphate, copper chloride, copper nitrate, copper acetate are dissolved in water and ethylene glycol respectively, above-mentioned mantoquita is readily soluble
Yu Shui generates blue liquid；And copper chloride ethylene glycol solution, at green, copper nitrate solution is at blackish green, copper sulphate and copper acetate
Solubility in ethylene glycol is lower.Fig. 1 (a) is in step 1 by mantoquita, including copper nitrate, copper chloride, copper sulphate, copper acetate,
The transmission spectrum of obtained copper salt solution soluble in water respectively, Fig. 1 (b) are by mantoquita, including copper nitrate, copper chloride, sulfuric acid
Copper, copper acetate are dissolved in mantoquita ethylene glycol solution transmission spectrum obtained in ethylene glycol respectively, and wherein copper sulphate ethylene glycol solution is
Emulsion, therefore be not discussed.As shown in Figure 1, the above copper salt solution, mantoquita ethylene glycol solution are shown in visible region
High transmittance, and acetic acid copper liquor and copper acetate ethylene glycol solution are also partially penetrated near infrared region, are unsatisfactory for mantoquita glue
Liquid prepares demand.
Fig. 2 is separately added into configured copper nitrate aqueous solution among the above, copper chloride solution, copper sulfate solution
A certain amount of PVP ethylene glycol solution, the transmission spectrum of gained difference mantoquita colloidal liquid.In each mantoquita colloidal liquid mantoquita with
The concentration of PVP is 3mol/L, and the volume ratio of water and ethylene glycol is less than 5.Mixed solvent mantoquita colloidal liquid is high to visible light thoroughly
It crosses, near-infrared absorption.Meanwhile ethylene glycol is not volatile, mantoquita colloid can keep wettability for a long time.
(a) and (b) is the reflection spectrogram and transmission spectrum of glass, single or double layer PET film respectively in Fig. 3.Light-transmitting substrate,
Including glass, single or double layer PET film, in visible light-near infrared region, transmitance is all larger than 85%.
(a), (b), (c) are that 3mol/L copper chloride colloidal liquid, 3mol/L copper nitrate colloidal liquid difference is uniform in Fig. 4
It is applied to transmission spectrum obtained in sheet glass, single-layer PET film and double-layer PET film.As seen from the figure, on various substrates, nitric acid
Copper colloidal liquid visible region is through spectral line is wider than copper chloride colloidal liquid and blue shift；Manufactured optical thin film is saturating in visible region
Rate is crossed greater than 80%, near infrared region less than 20%.
Using glue spreader by copper nitrate mucilage binding liquid applicator in double-layer PET film, when the viscosity of glue and concentration it is lower when,
It is uneven to be applied on film products obtained therefrom, the gravity the effects of under easily assemble；When concentration is greater than 3mol/L, uniform film can be obtained
Product.
Fig. 5 be the copper nitrate colloidal liquid (2mol/L, 3mol/L, 4mol/L) of various concentration is uniformly applied to respectively it is double
Transmission spectrum in layer PET film.
Using ultraviolet-visible-infrared spectrometer (UV-6300 and UV-3600) to mantoquita colloidal liquid obtained and optics
Film is tested, and is absorbed, is transmitted and reflectance spectrum accordingly, by spectrogram it is found that the absorption of mantoquita colloidal liquid exists
Near infrared region, optical thin film is high in visible region transmitance, and ultraviolet and near infrared region absorbs by force.
It is detected using ultraviolet-visible-infrared spectrometer (UV-6300), mantoquita colloidal liquid is uniformly applied to light transmission base
On material, select different mantoquitas that will all cause the change of light absorbent transmission spectrum as the variation of raw material and light-transmitting substrate material
Change.
It is detected using ultraviolet-visible-infrared spectrometer (UV-3600), the reflection coefficient of optical thin film is very low.
PET film and mantoquita colloidal liquid combination degree are excellent in the present invention, and without apparent in gravity test experiments
Fluid flow phenomenon.Mantoquita colloidal liquid thickness is uniform in entire PET film, thus still can be vertical after guaranteeing light vertical incidence
It projects, optical path deviation will not occur.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
