Embodiment Construction

[0020] The present invention discloses that the present invention provides a forming and processing method for preparing cross-linked high molecular polymer materials. The decomposition temperature of the ball; then the thermosetting crosslinked polymer nanospheres are pre-compacted to get rid of the gas in the thermosetting crosslinked polymer nanospheres; then according to the decomposition temperature, the The thermosetting cross-linked polymer nanospheres after the pre-compression are heated to soften the thermosetting cross-linked polymer nanospheres; then the softened thermosetting cross-linked polymers The polymer nano microspheres are cooled, and then the high molecular polymer material is produced. After the thermosetting cross-linked polymer is prepared into nano-sized high-strength microspheres, there are electrostatic repulsion, van der Waals force and volume repulsion among the high-strength microsphere particles, so that the dispersed emulsion of the polymer can ...

Abstract

The invention provides a forming and processing method for preparing cross-linked polymer materials, which belongs to the technical field of material processing. The method comprises obtaining the decomposition temperature of the thermosetting crosslinked polymer nanospheres based on the obtained thermosetting crosslinked polymer nanospheres; pre-pressing the thermosetting crosslinked polymer nanospheres Compaction while maintaining a high vacuum to remove the gas in the thermosetting cross-linked polymer nanospheres; according to the decomposition temperature, the thermosetting cross-linked polymer nanospheres after pre-compression heating to soften the thermosetting crosslinked polymer nanospheres; cooling the heated thermosetting crosslinked polymer nanospheres to produce a polymer material. The invention achieves the technical effect of reprocessing the high molecular polymer material under the conditions of lower than the decomposition temperature and high pressure during the preparation of the high molecular polymer material.

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...
