Description
[technical field]
The present invention relates to transparent resin film antifogging agent technical field, a kind of specifically antifogging agent constituent and methods and applications thereof.
[background technology]
Polyester resin sheet is the hydrophobic resin sheet; Its surface tension is low, when it is used for the refrigerated food packing, because the surface tension of water is higher; Its steam can the form with little water droplet form water smoke on the resin sheet surface; This just makes the transparent variation of wrapping material, and the content visibility reduces, thereby has reduced the magnetism to client.
Mainly be through using antifogging agent to address the above problem at present; With antifogging agent be coated on resin sheet surface or with its blend; To improve the surface tension and the wetting ability of resin sheet, reduce contact angle between resin sheet surface and the water, thereby make it can form a uniform thin layer; It is transparent that resin sheet still keeps, the optics obstacle that the discrete water droplet of having gone out causes.
It mainly is the hydrophilic surfactant active that tradition is used more antifogging agent; Like polysaccharide fatty acid tensio-active agent, though above-mentioned tensio-active agent has certain anti-fog effect, because the polysaccharide fatty ester has certain oiliness; Its coating back resin sheet oil stain is heavier, causes following problem
Film with the lines of the hand appear after hand contacts, outward appearance is defective;
After producing for some time, the roller of surface in contact promoting agent can be contaminated.
In order to address the above problem, can in above-mentioned tensio-active agent, add hydrophilic Z 150PH, it can reduce the oiliness of polysaccharide fatty ester, solves the oil stain problem that occurs.But the specification of Z 150PH is very big to the production influence of antifog resin sheet, and inappropriate specification can cause following problem:
Inhomogeneous, the antifog deleterious of spraying during production.
With poor, the antifog resin sheet of antifogging agent consistency become opaque.
[summary of the invention]
The objective of the invention is to solve the deficiency of prior art, a kind of antifogging agent constituent and methods and applications thereof are provided.
For realizing that above-mentioned purpose designs a kind of antifogging agent constituent, it is characterized in that said antifogging agent constituent by hydroxyl fatty ester, Z 150PH and solvent composition, wherein the weight ratio of hydroxyl fatty ester and Z 150PH is 0.1～10; The Z 150PH alcoholysis degree is 80～90%, viscosity is 5-10; Described solvent and water dissolve each other, and described hydroxyl fatty ester is Surfhope SE Cosme C 1216 or sucrose stearate, and described Z 150PH alcoholysis degree is preferred 88%, and Z 150PH viscosity is preferably 5.7, and described solvent is water or ethanol.
The present invention also comprises a kind of transparent antifog resin film that is coated with the antifogging agent constituent, comprises the resin film, it is characterized in that being coated with the antifogging agent constituent on the described transparent antifog resin film said antifog resin film mist degree≤4%.
The present invention also comprises a kind of method of antifogging agent constituent production resin film, it is characterized in that this method comprises the steps:
Be heated to 80～90 ℃ with alcoholysis degree is 80～90%, viscosity is 5-10 Z 150PH with solvent that water dissolves each other, stir 1 hour to dissolving fully;
Then, said hydroxyl fatty ester also stirs, and the weight ratio of hydroxyl fatty ester weight and Z 150PH is 0.1～10;
At last, with preparing transparent antifog resin film on the solution spraying that stirs to the said resin film.
The present invention also comprises a kind of application of antifogging agent constituent, it is characterized in that described antifogging agent constituent can be used for food product pack.
The present invention compares with prior art, can produce the good transparent resin sheet of anti-fog performance through the Z 150PH specification that this method adopts, and can not produce the oil stain problem, and through the production of long period, roller can be not contaminated yet.

In conjunction with specific embodiment, the present invention is done further explanation:
Embodiment 1:
Experimental raw:
Surfhope SE Cosme C 1216 125g
The PET film
Deionized water 4.875kg
Preparation technology:
Take by weighing the 125g Surfhope SE Cosme C 1216, join in the 4.875g water, be configured to antifog solution after stirring.With above-mentioned antifog solution spraying to PET film surface, prepare antifog PET film.
Embodiment 2:
Test raw material:
Preparation technology:
Take by weighing the 50g Z 150PH; Join in the 4.875kg water, be heated to 80～90 ℃, stir after 1 hour to dissolving fully; In this aqueous solution, add the 125g Surfhope SE Cosme C 1216; Be configured to antifog solution after stirring, above-mentioned anti-fogging liquid is sprayed into PET film surface, promptly prepare antifog PET film.
Embodiment 3:
Change the Surfhope SE Cosme C 1216 among the embodiment 2 into sucrose stearate, its wetting ability is less than Surfhope SE Cosme C 1216, and preparation technology is constant.
Embodiment 4:
Z 150PH specification among the embodiment 2 is changed into: alcoholysis degree 88%, viscosity 22.4, preparation technology is constant.Excessive because of its viscosity, cause spraying inhomogeneous, antifog deleterious.
