Abstract
The present invention relates to the use of the ultraviolet absorber UV327 as yellow toner in light diffusing PC. The ultraviolet absorbent UV327 as yellow toner is added into the light diffusion PC raw material in a proportion of 0.0001-0.1%, so that the yellow index of the product can be improved, and the light transmittance of the product is not reduced.
Description
Technical Field
The invention relates to the technical field of modification of high polymer materials, in particular to application of an ultraviolet absorbent UV327 as a yellow toner in light diffusion PC.
Background
The light diffusion PC composition is a modified plastic raw material, mainly comprises PC resin and a light diffusion agent, and can be made into lighting covers with different shapes by different processing methods such as injection molding, injection blowing, extrusion and the like.
In actual production, customers can provide standard color samples and require color consistency. The lampshade made of the light diffusion PC is mainly white, and the color modulation at the moment is mainly fine adjustment of the hue. In practice, it is found that when the pigment and dye which are conventionally used in the plastic industry are adopted, even if the addition amount is small, such as in the range of 0.0001% to 0.01%, the light transmittance of the product can be obviously reduced.
Disclosure of Invention
The inventor in practice surprisingly found that the yellow color index of the product, namely the b value in the colorimetric value lab can be improved without reducing the light transmittance of the product by adding the ultraviolet ray absorber UV327 as a yellow toner to the raw material of the light diffusion PC in a proportion of 0.0001-0.1%, thereby obtaining the invention of the application.
Ultraviolet absorber UV327 has the scientific name 2- (2 ' -hydroxy-3 ', 5 ' -di-tert-butyl) -5-chloro-benzotriazole with CAS number 3864-99-1, and is commonly used in the plastics industry as an ultraviolet absorber.
Detailed Description
The PC, the light diffusant, the antioxidant, the lubricant, the toner and other raw materials are uniformly mixed in a mixer, added into a double-screw extruder for mixing, cooled, cut into particles, dried and injected to prepare the color plate for color measurement.
A commercially available lamp was taken, the original lamp shade was removed, and the self-made color plate was used instead of the lamp shade to test the light transmittance.
The test methods and instruments in the examples are as follows:
the color measuring instrument adopts a DATACOLOR color measuring instrument, and has the following model: and (4) carrying out microflash.
The light transmittance tester adopts a 1.5-meter integrating sphere and an HP200 intelligent photometer which are produced by Hangzhou rainbow spectrum photoelectric technology limited company.
The method of light transmittance is: the bulb is placed in the integrating sphere, electricity is conducted, the bare lamp measures the lumen value L1, the lampshade is covered, the lumen value L2 is measured, and the light transmittance is = L2/L1 × 100%.
From a comparison of the examples, blanks and comparative examples, it can be seen that:
when UV-327 was added at 0.05%, a yellowness index with a b-value of 0.92 was produced. When 4 common yellow pigments and dyes are used to reach the same yellowness, the light transmittance of the product is reduced. Further, these yellow pigments and dyes have a strong coloring power, and are expressed by the fact that the amount of addition thereof is small, but this is disadvantageous for the purpose of hue adjustment, because the excessively small amount of addition extremely easily causes problems such as weighing errors and uneven mixing. The addition amount of the UV-327 used as the toner can meet the requirements of easy weighing, easy and uniform mixing and low cost.
Claims (3)
1. The application of the ultraviolet absorber UV327 as yellow toner in the light diffusion PC is as follows: the ultraviolet absorber UV327 is added to the raw material of the light diffusion PC in a proportion of 0.0001-0.1% to function as a yellow toner.
2. The effect of the yellow toner according to claim 1, specifically, an increase in the yellow index, that is, an increase in the b value in the colorimetric value lab.
3. The method of claim 1, wherein the ultraviolet absorber UV327 is added to the raw material of light-diffusing PC in a ratio of 0.0001-0.1% to function as a yellow toner without lowering the light transmittance of the product.
