1. the protective film is integrally designed on the liquid crystal display panel, and comprises the antistatic layer, the base layer and the radiation-proof layer, and the liquid crystal display panel with the protective film can have a better radiation-proof effect when in use.
2. According to the invention, the organic strontium modified auxiliary agent is used as the modified auxiliary agent of the polycarbonate, so that the water resistance of the polycarbonate is improved, and the radiation-proof layer can be better attached to the base layer. Although polycarbonate is excellent in heat resistance and impact resistance, it is poor in hydrolysis resistance and is easily corroded by moisture in an environment with high humidity for a long time. According to the invention, strontium carbonate disodium ethylene diamine tetraacetate is used as a chelating agent, and strontium carbonate with good water resistance and isophthaloyl dichloride are chelated, so that the polycarbonate has excellent water resistance. The organic strontium modification auxiliary agent is formed by chelating and combining strontium carbonate, isophthaloyl dichloride and disodium ethylene diamine tetraacetate to form an inorganic-organic chelate, and by the method, the isophthaloyl dichloride and the disodium ethylene diamine tetraacetate can be chemically grafted into a pore channel of the metal-organic coordination polymer.
3. According to the invention, the modified carbon nanotube fiber is added in the radiation-proof layer to enhance the scratch resistance of the polycarbonate. Although polycarbonate has stronger impact resistance and processability, the scratch resistance of polycarbonate is poorer, therefore, the invention obtains a microporous carbon material with a three-dimensional structure by specifically thermochemically treating a metal carbon compound, and tantalum has stronger scratch resistance, the carbon material with the three-dimensional structure can be combined with tantalum metal to form an in-situ carbonized network structure, compared with the singly doped carbon material or tantalum metal, the combination generates a synergistic enhancement effect, and the scratch resistance performance and the stability of the high-altitude polycarbonate can be further improved.
4. The antistatic agent is prepared by preparing barium perrhenate to participate in the synthesis of polyaniline, so that the polyaniline is modified to obtain the modified polyaniline. Polyaniline has special electrical and optical properties and is suitable for serving as an antistatic agent, however, polyaniline can be gradually degraded along with the use time, a diphenylamine structure is easily generated during degradation, and the compound has a carcinogenic effect, so that the use of the compound is limited by the properties. According to the invention, barium perrhenate is produced by reacting barium nitrate with rhenium heptoxide under the action of sodium hydroxide, and then the barium perrhenate participates in the polymerization reaction of aniline to generate modified polyaniline, wherein the barium perrhenate has stronger stability, and a three-dimensional network structure is formed after nanoparticles are prepared and coated by the polyaniline. The modified polyaniline prepared by the method has higher conductivity, lower alternating current impedance and larger electroactive surface area, and in addition, the addition of the barium perrhenate improves the degradation difficulty of the polyaniline, prolongs the service life of the polyaniline and further limits the degradation of the polyaniline.
