The invention discloses a colorful acid and alkali resistant laser printing ink and a preparation method thereof. The printing ink is composed of the following components in parts by weight: 0 to 30 parts of butanone, 10 to 30 parts of isopropanol, 2 to 6 parts of curing agent, 10 to 15 parts of pigment, and 10 to 30 parts of glycidyl ether epoxy resin. The glycidyl ether epoxy resin is adopted to produce the printing ink, aliphatic polyamine is further chosen as the curing agent, the acid and alkali resistant performance of the printing ink is strengthened through optimizing the formula, thus the shortage that the colorful laser printing ink is lost when being mixed with acid and alkali is overcome, moreover, the color of the laser printing product is more abundant, and the patterns are more clear.

The application discloses an anti-oxidation fermented Chinese herbal medicine mixed substitute tea and a preparation method thereof, and relates to the technical field of substitute tea processing and preparation. The anti-oxidation fermented Chinese herbal medicine mixed substitute tea comprises Sanghuang, Huangqi, Huangjing, Renshen and Gouqi, and the weight ratio of the raw materials is as follows: Sanghuang:Huangqi:Huangjing:Renshen:Gouqi = 4:2:2:1:1. The preparation method comprises the following steps: crushing, fermentation, drying, sterilization, sub-packaging, vacuum sealing, outer packaging, sampling quality inspection and storage in a warehouse. The anti-oxidation fermented Chinese herbal medicine mixed substitute tea is prepared by using a specific formula and biological fermentation of Inonotus hispidus, and the dissolution rate of anti-oxidation active ingredients of Chinese herbal medicines is significantly improved, and the anti-oxidation capacity is far superior to that of conventional physical mixed substitute tea. The fermentation process can efficiently degrade the cell walls of Chinese herbal medicines, so that the polysaccharides and other core anti-oxidation substances in Sanghuang, Huangqi, Huangjing, Renshen and Gouqi are fully released, DPPH, hydroxyl and other free radicals can be directly removed, and the Keap1-Nrf2-ARE signal path in the body can be activated, so that the anti-oxidation defense system of the body is doubly strengthened, and the anti-oxidation effect is improved from the root.

The present invention relates to a semi-quantitative urine zinc test strip, a preparation method and application thereof, and belongs to the field of analysis and detection. A semi-quantitative urine zinc test strip is provided, which includes a zinc test strip; the zinc test strip is obtained by soaking and drying the test strip in a substrate impregnation liquid, and the substrate impregnation liquid includes: 0.01% by mass of 2-(5-bromo-2-pyridyl azo)-5-[N-propyl-N-(3-sulfopropyl) amino] phenol disodium salt, 0.5-1M N-2-hydroxyethylpiperazine-N'-2-ethanesulfonic acid, 0.1%-1% by mass of polyethylene glycol monooctylphenyl ether, 1%-5% by mass of a masking agent, and the solvent is deionized water; wherein the masking agent includes sodium hexametaphosphate and N'-(sodium toluenesulfonate) thiourea. This urine zinc semi-quantitative test strip can realize visual distinction and interpretation of low concentration zinc ions, and has strong anti-interference ability and high accuracy, making it suitable for home use.

The application relates to the technical field of wood decoration materials, and particularly discloses a wood surface composite structural color protective layer and a preparation method. The application first self-assembles and constructs a structural color layer on the wood surface; then applies PVB ethanol solution, and forms a PVB layer which internally strengthens the structural color layer in a dot-shaped bonding mode after drying; and finally coats UV paint and forms an outer protective layer through ultraviolet light curing. The PVB layer of the application effectively strengthens the cohesive force and the adhesion to the substrate without destroying the order of the structural color layer; the UV paint layer is firmly combined with the PVB layer through possible chemical bonding, and excellent wear resistance and scratch resistance are provided. The two are synergistic, solve the technical problem that the adhesion of the traditional wood surface structural color layer is poor and the structural color layer is easily damaged, and the prepared color protective layer is bright in color and has a wide application prospect.

The invention relates to a preparation method of a pixel defining layer, and aims to realize a colored pattern with high optical density on an electrode substrate, so that the color becomes bright, the reliability of a display is improved, and the service life of the display is prolonged. In order to contain the colorant, improve the optical density after the post-baking treatment process and reduce the roughness, a pigment dispersion liquid with the pigment size of less than 100 nm is adopted. In addition, the water content after the post-baking process is completed is minimized, so that the service life shortening caused by water in the panel state can be minimized.
