Forming processing method for preparing cross-linked high-molecular polymer material

Abstract

The invention provides a forming processing method for preparing a cross-linked high-molecular polymer material, and belongs to the technical field of material processing. The method comprises the steps that thermosetting cross-linked high-molecular polymer nano-microspheres are obtained; according to the obtained thermosetting cross-linked high-molecular polymer nano-microspheres, a decompositiontemperature of the thermosetting cross-linked high-molecular polymer nano-microspheres is obtained; the thermosetting cross-linked high-molecular polymer nano-microspheres are prepressed and compacted, at the same time, kept in high vacuum to exclude gas in the thermosetting cross-linked high-molecular polymer nano-microspheres; according to the decomposition temperature, the prepressed and compacted thermosetting cross-linked high-molecular polymer nano-microspheres are heated, so that the thermosetting cross-linked high-molecular polymer nano-microspheres are softened; the heated thermosetting cross-linked high-molecular polymer nano-microspheres are cooled, so that the high-molecular polymer material is prepared. According to the method, the technical effect is achieved that in the process of preparing the high-molecular polymer material, and under the conditions of below the decomposition temperature and high pressure, the polymer material is once again processed and formed.

Description

technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to a forming processing method for preparing cross-linked polymer materials. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction of monomer as raw material, commonly known as plastic or resin, and its composition and shape can be changed freely. The main component of plastic is resin, such as rosin, shellac, etc., and resin refers to a polymer compound that has not been mixed with various additives. Resin accounts for about 40% to 100% of the total weight of the plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins with no or few additives, such as plexiglass, polystyrene, polycarbonate, etc. [0003] At present, high-molecular polymer mat...
