Background
The polyvinyl chloride (PVC) blue light-proof high-transmittance plate is mainly applied to the protective covers of intelligent workshops and photosensitive component manufacturing workshops, and is a functional protective material. The main function is to block ultraviolet rays and blue light with the wavelength of 280 nm-460 nm and prevent the light wave of the wavelength from damaging the photosensitive element. The plate has the advantages of light weight, easy installation, high transparency and the like, and is widely applied to the intelligent manufacturing fields of displays, precise electronic parts and the like. In recent years, although domestic enterprises increase research and development investment and aim to improve the quality of blue-light-proof high-transparency PVC plates, core problems are not solved, such as: the sheet material can not be blocked in all wave bands, has low light transmittance, high haze, multiple surface crystal points and the like, and greatly influences the quality improvement of the sheet material and the expansion of the application field. At present, domestic and foreign enterprises produce high-transparency PVC plates by adopting an extrusion process, and the method comprises the following steps: foreign enterprises: the modified PVC resin is modified in the polymerization process of the PVC resin, and the resin and the blue-light-proof auxiliary agent are mixed in a molecular level, so that the mixed resin has high cost and is not sold at home. Domestic enterprises: the blue light prevention auxiliary agent is added and mixed with resin for melt extrusion, but the formula process is immature, the dispersibility is too poor, the functional target cannot be achieved, and in production, because the opening of a film lip is large, the melt strength of a blank after the film is produced is low, the surface is dull, the light transmittance is poor, and the final product is poor. In addition, the addition of a large amount of additives also increases precipitates in the production process, so that the production stop times are increased, and the production cost and the surface quality of products are invisibly increased. Currently, the development trend of PVC plates is: the PVC plate is functional, environment-friendly and durable, so that a product meeting the development trend of the current high-transmittance PVC plate is imperatively developed for producing high-performance plates.
