Embodiment
Below by embodiment, the invention will be further described.
A kind of UV color barrier agent, it is characterized in that: comprise UV light absorber and tinting material, described UV light absorber is for can absorb ultraviolet organism below 370nm, described tinting material is the dyestuff that dissolves in plastics, and this UV light absorber and dyestuff make the UV color barrier agent can shielding of ultraviolet and be not less than the visible ray of 450nm; Wherein tinting material is one or more in yellow, orange, green or brown, and in the present invention, tinting material is containing yellow.
A kind of manufacture craft of the PET bottle that contains this UV color barrier agent, in the time making PET bottle, in PET raw material, add above-mentioned UV color barrier agent, PET raw material and UV color barrier agent consisting of by weight percentage: PET raw material 97-99, ultraviolet-resistant absorbent 0.01 to 2, tinting material 0.02-2 in UV color barrier agent; The raw material of PET by weight percentage in the present embodiment is 98, and ultraviolet-resistant absorbent is 0.8, and tinting material is 1.2, and tinting material is yellow.
Shown in Fig. 1, the PET bottle that contains UV color barrier agent transmittance after wavelength is 470nm of making according to above-mentioned technique rises gradually, and this kind of PET bottle can absorb ultraviolet ray below 400nm and the visible ray below 470nm as seen.
Shown in Fig. 6, common PET bottle, the PET bottle that contains UV light absorber and the PET bottle that contains UV color barrier agent are carried out to simultaneous test:
One, object and method
(1) selection of sample sample: the beverage that contains lemon yellow.
(2) test method: the beverage that contains lemon yellow is put into the PET bottle that contains UV color barrier agent, natural light Exposure to Sunlight;
Control group: in the PET bottle that the beverage that contains lemon yellow of equivalent is respectively charged into common PET bottle and contains UV light absorber, natural light Exposure to Sunlight;
Test period: 15 days.
(3) physical data, is shown in Fig. 1, Fig. 2.
Visible with reference to Fig. 1, common PET is in the time that wavelength is 310nm, and transmittance rises gradually, has been both that 310-400nm ultraviolet ray does not almost shield to wavelength;
The PET bottle that contains UV light absorber is in the time that wavelength is 350nm, transmittance rises gradually, both the PET bottle that had contained UV light absorber can intercept the ultraviolet ray below 350 nanometers, but to seldom shielding of the ultraviolet ray between 350 nanosection, nanometer-400, the visible region of 400 nanometer-700 nanometers does not shield;
The PET bottle that contains UV color barrier agent is in the time that wavelength is 470nm, and transmittance starts to rise, and the PET bottle that had both contained UV color barrier agent can stop whole ultraviolet rays and the visible ray below 470nm.
Visible with reference to Fig. 2, the beverage that contains lemon yellow is in the time that wavelength is 325-440nm, beverage transmittance falls gradually, both the beverage that had contained lemon yellow in the time that wavelength is 325-440nm is larger to the absorption of light, the lemon yellow of light more easily and in beverage reacts, and causes beverage variable color, affects drink flavour.
Two, test-results
(1) impact of PET bottle on beverage light absorption ratio, is shown in Fig. 4, Fig. 5, Fig. 6;
Be loaded on the beverage in common PET bottle, be subject to having the greatest impact of Exposure to Sunlight;
Be loaded on the beverage in the PET bottle that contains UV light absorber, the impact that is subject to Exposure to Sunlight is less than the beverage being loaded in common PET bottle;
Be loaded on the minimum that affects that is subject to Exposure to Sunlight containing the beverage in the PET bottle of UV color barrier agent.
(2) Exposure to Sunlight consequence is loaded on the beverage colour intensity contrast in each PET bottle, in table 6.
Before Exposure to Sunlight, the colour intensity of beverage is 0.625;
Being loaded on containing the beverage colour intensity in the PET bottle of UV color barrier agent is 0.575;
The beverage colour intensity being loaded in the PET bottle that contains UV light absorber is 0.45;
The beverage colour intensity being loaded in common PET bottle is 0.4.
Three, conclusion
Through paired observation, be loaded on containing the colour intensity of beverage before the beverage colour intensity in the PET bottle of Exposure to Sunlight barrier agent and Exposure to Sunlight the most approaching, both the destruction minimum of light to beverage in PET bottle, PET bottle containing Exposure to Sunlight barrier agent is the most obvious to the protection of beverage, its major cause is: UV light absorber and yellow tinting material exist with molecularity in PET bottle, be distributed in completely equably on each position, wherein ultraviolet isolating agent absorbs the ultraviolet ray below 370nm, tinting material can first absorb to the light reacting with lemon yellow in natural light the yellow of self-assembling formation on PET bottle, thereby UV light absorber and yellow colorants match, make UV color barrier agent can effectively intercept ultraviolet ray and the following visible ray of 470nm, beverage in PET bottle is effectively protected, extend the quality guaranteed period of beverage, color and luster and local flavor.
Above are only a specific embodiment of the present invention, but design concept of the present invention is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the present invention, all should belong to the behavior of invading protection domain of the present invention.
