A preparation method of the ultraviolet-proof, short-wave and blue-light PVC preservative film comprises the following steps: dissolving the phenyl salicylate in ethanol; violently stirring until the phenyl salicylate is dissolved completely; adding in a kilogram of the PVC masterbatches; drying the mixture at the temperature of 50 DEG C; after mixing the prepared mixed masterbatches, the dioctyl adipate, the soybean oil, the silane coupling agent KH550 and the glycol according to the proportion, mixing evenly in a high-speed mixer; and then carrying out extrusion, filtering, casting cooling, dragging edge cutting and reeling on materials which are mixed evenly; and preparing ultraviolet-ray-absorbing PVC preservative film with different proportions according to difference of the proportions of phenyl salicylate and glycol. Absorption of the prepared PVC preservative film to light within 200-700 nm is measured by an ultraviolet-visible spectrophotometer. Measured 450 nm light transmittance is 79.32, 400 nm light transmittance is 1.57, and 350 nm light transmittance is 0.01.
Description
The invention belongs to technical field prepared by preservative film based packaging material, ultraviolet can be intercepted particularly to one
The method of the preparation of line PVC fresh-preserving film.
Technical background
As a kind of packaging material, PVC fresh-preserving film can intercept dust: has certain breathability, enables air to
Enough pass through, thus suppress the growth of anaerobe；And the content of certain moisture can be kept, thus extend food
Freshness date.Fresh food can rot to ruin, and one of the main reasons is in placement process, food aging and draw
Rise denaturalization phenomenon, such as starch not aged time molecules align closely, aging after molecules align
The most loose, even can become pasty state, thus for the invasion of antibacterial with rot and create condition.
In natural light, ultraviolet accounting example is about 4%, and its wavelength is under 380nm, and blue light is visible
The important component part of light, its wavelength is between 380-480nm.Ultraviolet and blue light wavelength are short, and energy is high,
The molecule on fresh food surface can be destroyed, promote the aging of food and the generation ruined of rotting.If by ultraviolet
Line and blue light absorption, make fresh food avoid the irradiation of high energy light in processing accumulating, processing procedure, delay
Aging and the generation ruined of rotting of food such that it is able to extend shelf life and the safety of fresh food.
Salicylic acid esters is a kind of organic compound that can absorb ultraviolet light, is tied with PVC material by salicylate
Preparing the compatibility altogether good, ultraviolet and blue light preservative film packaging material that energy absorbing wavelength is short are the present invention
Main intention and thinking.
Summary of the invention
The technical problem to be solved is: for the deficiencies in the prior art, it is provided that a kind of preparation process letter
Single, appliance arrangement requires ultraviolet low, that the compatibility good, energy absorbing wavelength is short and blue light preservative film packaging material
Preparation method.
The present invention solves its technical problem and uses following technical scheme:
What the present invention provided prepares the short ultraviolet of energy absorbing wavelength and the method for blue light preservative film packaging material, is
The method that employing comprises the following steps:
The phenyl salicylate of 10 grams is dissolved in the ethanol of 1L by the first step, is stirred vigorously, until being completely dissolved.
The solution that the first step prepares is joined in the PVC masterbatch of 1 kilogram by second step, is stirred vigorously, waits to stir
After even, at 50 DEG C, this mixture is dried.
3rd step is by mixing masterbatch prepared for second step, adipic acid dibutyl ester, soybean oil, silane coupler
KH550, ethylene glycol proportionally mix at 68: 21: 9: 0.9: 1.0.Wherein phenyl salicylate accounts for always
Ratio is 0.68%.I.e. phenyl salicylate: adipic acid dibutyl ester: soybean oil: Silane coupling agent KH550: second
Glycol is 0.68: 21: 9: 0.9: 1.0
4th step mix homogeneously in high-speed mixer by a certain percentage, then by the material of mix homogeneously through squeezing
Go out, filter, be cast cooling, traction trimming and rolling.According to phenyl salicylate, ethylene glycol proportion not
With, prepare the absorption ultraviolet PVC fresh-preserving film of different proportion.
5th step by ultraviolet-visible spectrophotometer measure prepared by PVC fresh-preserving film at 200-700nm
Between absorbing state to light.Method, for making a square frame after being stretched by PVC fresh-preserving film, is positioned over instrument
In, make light pass through film, detector can detect the light passed through.
First the present invention contains the PVC masterbatch of ultraviolet absorber phenyl salicylate, then by masterbatch and plasticizer,
Stabilizer, antifoggant mix, and are uniformly dispersed, and prepare different ultraviolet and the blue light of can absorbing after molding
PVC fresh-preserving film.
The present invention uses above-mentioned preparation method, different mixed proportions can obtain the material that light absorption performance is different
