TABLE 1
TABLE 2
| Comparative example 1 | Comparative example 2 | Comparative example 3 | |
| Transmittance of ultraviolet ray | 64 | 38 | 46 |
| Tensile strength | 47 | 54 | 49 |
According to the comparison of the data of comparative example 1 and comparative example 2 in table 2, the composition of comparative example 2 is added with p-hydroxybenzoic acid, the ultraviolet transmittance of comparative example 2 is lower than that of comparative example 1, and the tensile strength of comparative example 2 is higher than that of comparative example 1, which shows that by adding p-hydroxybenzoic acid, the carboxyl on p-hydroxybenzoic acid and the hydroxyl on the adjacent p-hydroxybenzoic acid are easy to generate esterification reaction to generate ester with benzene ring, the conjugated structure system of benzene ring is easy to absorb ultraviolet light, thus being beneficial to reducing the ultraviolet transmittance of plastic packaging bottles for skin care products; meanwhile, the molecules are mutually crosslinked to form a net structure through mutual reaction between adjacent pairs of the hydroxy formic acid, so that the stability of molecular chains is favorably improved, and the tensile strength of the skin care product plastic packaging bottle is favorably improved.
According to the comparison of the data of comparative examples 1-3 in table 2, the component of comparative example 2 is added with p-hydroxybenzoic acid, the component of comparative example 3 is added with phenylpropanolamine, the ultraviolet transmittance of comparative examples 2 and 3 is lower than that of comparative example 1, the tensile strength of comparative examples 2 and 3 is higher than that of comparative example 1, meanwhile, the ultraviolet transmittance of comparative example 2 is lower than that of comparative example 3, and the tensile strength of comparative example 2 is higher than that of comparative example 3, which shows that the ultraviolet transmittance of the plastic packaging bottle for skin care products can be reduced by adding p-hydroxybenzoic acid or phenylpropanolamine alone, and the tensile strength of the plastic packaging bottle for skin care products is enhanced, and shows that the ultraviolet transmittance of the plastic packaging bottle for skin care products and the tensile strength of the plastic packaging bottle for skin care products can be reduced to a certain extent by containing benzene rings in the components, however, since the adjacent molecules of parahydroxybenzoic acid are easily reacted with each other, and the molecules are easily cross-linked to form a network structure, the effect of adding parahydroxybenzoic acid alone is better than that of adding phenylpropanolamine alone.
Comparing the data of examples 1-3 in table 1 with the data of comparative examples 2-3 in table 2, it can be seen that, when both p-hydroxybenzoic acid and phenylpropanolamine are added to examples 1-3, only p-hydroxybenzoic acid is added to comparative example 2, only phenylpropanolamine is added to comparative example 3, the ultraviolet transmittance of examples 1-3 is lower than that of comparative examples 2-3, and the tensile strength of examples 1-3 is higher than that of comparative examples 2-3, which indicates that the reaction between p-hydroxybenzoic acid and phenylpropanolamine occurs by adding both p-hydroxybenzoic acid and phenylpropanolamine, so that the number of benzene rings on the molecules is increased, and the intermolecular cross-linking is facilitated to form a network structure, thereby facilitating the tensile strength to be enhanced while the ultraviolet transmittance is reduced.
According to the comparison of the data of examples 1-3 and examples 4-6 in table 1, the mica powder, acrylic fiber, antioxidant, white mineral oil, dispersant and nano titanium dioxide are added to the components of examples 4-6 compared with examples 1-3, the ultraviolet transmittance of examples 4-6 is lower than that of examples 1-3 and the tensile strength of examples 4-6 is higher than that of examples 1-3, which shows that the ultraviolet transmittance of the plastic packaging bottle for skin care products can be reduced to a certain extent and the tensile strength of the plastic packaging bottle for skin care products can be enhanced by adding the mica powder, acrylic fiber and nano titanium dioxide.
