Preparation method for novel modified high molecular material

Abstract

The invention provides a preparation method for a novel modified high molecular material. The preparation method comprises the following steps: crushing artemisia vulgaris with a crusher to obtain artemisia vulgaris powder, adding the artemisia vulgaris powder into a supercritical carbon dioxide extraction pond to be extracted for 24 hours to obtain an extraction solution, secondarily extracting the extraction solution with ethyl ether, separating an artemisia vulgaris liquid layer and drying the artemisia vulgaris liquid layer with a blowing drier to obtain artemisia vulgaris extract for later use; inputting natural rubber and EVA510 into an open mill to carry out open milling, wherein the roller spacing of the open mill is 1-3 mm, and carrying out thin-passing for 8-12 times to obtain anopen mill substance; adding the open mill substance, percarbamide, zinc oxide and light calcium carbonate together into an internal mixer to be mixed at 75-85 DEG C for 7-12 minutes to obtain a mixture; and adding the artemisia vulgaris extract, the mixture, zinc stearate, L-butyl lactate, 8-12 parts of tert-butyl ethyl malonate and 3-5 parts of azodicarbonamide into the internal mixer to be mixed, mixing the mixture by setting temperatures of the front, middle and back sections of the internal mixer at a rotating speed of 60-80 rpm for 40-60 minutes, and cooling the mixture to obtain the novel modified high molecular material.

Description

technical field [0001] The invention relates to the technical field of preparation of new materials, in particular to a preparation method of a modified polymer new material. Background technique [0002] At present, the materials used to manufacture shoe soles are mainly ordinary rubber, TPR thermoplastic rubber, and PU polymer polyurethane synthetic materials. Ordinary rubber is heavy, easy to spit frost, not easy to corrode, and not environmentally friendly. TPR thermoplastic rubber has poor anti-slip performance, heavy weight, and easy to turn yellow, while PU polymer polyurethane synthetic material has strong water absorption, easy yellowing, Easy to break, poor elongation, not resistant to water, easy to rot. [0003] In recent years, EVA resin has been gradually used in the field of shoe materials. In the EVA resin used in shoe materials, the content of vinyl acetate is generally 15%-22%. Compared with polyethylene, due to the introduction of vinyl acetate monomer i...

Problems solved by technology

In the process of shoemaking, most of the existing shoe soles are made of EVA materials with strong smell and smell and various additives through mixing, foaming or secondary foaming. The material itself smells very bad. It is easy to make shoes smelly; in addition, the soles made of traditional EVA material foaming or secondary foaming are also very poor in air permeability, making it easier for people to smell when wearing them.

However, the soles made of some other odorless materials cannot guarantee the comfort and slip resistance of the shoes.
