A preparation device for easily recyclable, rewritable polymer information material

Abstract

The invention discloses a preparation device of a polymer information material that is easy to recycle and can be erased and written repeatedly, and relates to the technical field of polymer information materials. The wall is fixedly connected with a mounting plate, the upper end side wall of the mounting plate is provided with a placement slot, the printing body is placed in the placement slot, the inner side wall of the placement slot is provided with a mounting slot, and a positioning slot is installed in the mounting slot mechanism, the lower end side wall of the positioning mechanism is fixedly connected with a pull rod, the lower end side wall of the mounting plate is provided with a through groove, the pull rod penetrates through the through groove and extends to the lower part of the mounting plate, and the lower end side wall of the mounting plate is provided with a through groove. A through groove is provided, and the fixing of the printing body is realized through the cooperation between the positioning mechanism and the placing groove, thereby avoiding the shaking of the printing body during the erasing process, and facilitating the erasing work.

Problems solved by technology

[0002] Since polymers were officially named in 1920, plastic has become the most widely used material in the world in just 100 years. According to statistics, the global plastic consumption in 2016 reached 500 million tons, with an average annual market value of nearly 1.06 trillion US dollars , "Printed plastic", that is, plastic printed with patterns or text, is the core material of plastic packaging, but because printed plastic contains specific dyes, it is difficult to recycle and reuse, and this type of plastic is often used due to extremely high recycling costs. Discarded, and because it is difficult to degrade, it has become the source of white pollution;

[0003] As a substitute for traditional printed plastics, rewritable materials are a new type of information recording medium that can be reused many times through the "write-erase-write" process. For this new type of polymer material, during the erasing process, It needs to be processed to realize the softening of the information material, and then the softened material can be erased. After the erasure is completed, the regeneration and reshaping of the polymer information material can be realized through follow-up work. Due to the lack of such materials on the market Such devices lead to the inability to recycle high-information molecular materials, which not only causes waste of materials, but also pollutes the atmospheric environment. Therefore, we propose an easy-to-recycle, rewritable high-molecular information material. preparation device to address the issues raised above
