Performance test
Detection method/test method
1. Tensile Strength test
The protective films for electronic products obtained in examples 1 to 8 and comparative examples 1 to 5 were subjected to tensile strength tests using the method described in GB/T13022-.
2. Blue light resistance test
The electronic products prepared in examples 1-8 and comparative examples 1-5 were tested for blue light resistance by using the protective film, and the blue light blocking rate (430-: taiwan wisdom-ALP-01 blue light obstruction tester. The test data are shown in table 4.
3. Light transmittance test
The electronic products prepared in examples 1 to 8 and comparative examples 1 to 5 were subjected to a light transmittance test using a protective film, in which: donghu DR-60A light transmittance detector. The test data are shown in table 4.
Table 4: test data
As can be seen from the combination of example 1 and comparative example 1 and table 4, the protective film for electronic products prepared by the method of example 1 has a good blue light resistance effect, and has a good light transmittance, i.e., high transmittance. The reason may be that since the blue-light-resistant powder is directly added to the mixing in the manufacturing process, rather than the surface coating layer is formed by coating, light does not need to pass through an additional medium when passing through the protective film, so as to improve light transmittance. In addition, the technical scheme in the application can directly place the blue-light-resistant powder into the raw materials for mixing, so that the operation steps are simpler and more convenient, and the production cost is reduced.
By combining the example 2 and the comparative example 2 and combining the table 4, it can be seen that the protective film for electronic products has better blue light resistance effect and light transmittance after the blue light resistance powder and the 1, 6-hexanediol diacrylate are added. It can be seen from the combination of example 2 and comparative example 3 and table 4 that, when only 1, 6-hexanediol diacrylate was added during the production of the protective film for electronic products, the blue light resistance of the protective film for electronic products was not substantially improved, and the tensile strength of the protective film for electronic products was slightly lowered. Combining example 2 and comparative example 4 with table 4, it can be seen that the blue light resistance effect of the protective film for electronic products can be improved by adding only the blue light resistance powder, but the tensile strength is excessively reduced. From the analysis, the blue light resistant powder and the 1, 6-hexanediol diacrylate have a synergistic effect, so that the protective film for the electronic product has better blue light resistance, the tensile strength of the protective film for the electronic product is kept, and an unexpected effect is achieved. The reason for this is probably because the 1, 6-hexanediol diacrylate can improve the tensile strength of the protective film for electronic products by cooperating with polyacrylate, Muyu stone balls and nano aluminum oxide in the blue light resistant powder.
As can be seen from the combination of example 3 and comparative example 5 and table 4, when the commercially available blue light resistant powder is directly added to the protective film for electronic products, although the blue light resistant effect can be improved, the blue light resistant effect is greatly reduced compared to the case where the film is formed on the surface of the protective film as a coating method, and in addition, the tensile strength and the light transmittance of the protective film for electronic products are also reduced.
By combining examples 1-4, examples 5-7 and table 4, it can be seen that when the modified Muyu stone powder is used as the blue light resistant powder, the prepared protective film for electronic products has better blue light resistance and improved tensile strength. The reason for this is probably that in the process of modifying the wooden fish stone powder, the ethylene bis stearamide is added to be better wrapped in the beta-cyclodextrin in cooperation with the wooden fish stone powder, and because the modified wooden fish stone powder is microencapsulated and the shell is the beta-cyclodextrin, the modified wooden fish stone powder is easier to cooperate with other components in the blue light resistant powder to absorb blue light, and before this, the modified wooden fish stone powder is easier to disperse in the mixing raw material, so that all the substances in the mixing raw material are more uniformly dispersed.
As can be seen from examples 1 and 8 in combination with table 4, when cyclohexane 1, 2-dicarboxylic acid diisononyl ester is used as the plasticizer, the protective film for electronic products has better tensile strength than that of methyl phthalate.
As can be seen by combining examples 1-7 and Table 4, the protective film for electronic products has better light transmittance and tensile strength when the weight ratio of the blue-light-resistant powder to the 1, 6-hexanediol diacrylate is 1 (1-1.5), and has better effect when the weight ratio of the blue-light-resistant powder to the 1, 6-hexanediol diacrylate is 1: 1.2.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
