A kind of preparation method of go/nr composite material and open mill for preparation thereof

Abstract

The invention discloses a preparation method of GO / NR composite material, comprising the following steps: S100, placing silicon dioxide, deionized water and GO aqueous solution in a stirrer and stirring, and dispersing into GO-SiO by a high-speed shearing machine 2 Mixture; S200, to GO‑SiO 2 Add 100 parts by mass of centrifuged concentrated natural latex to the mixture, and vibrate with ultrasonic waves to obtain GO‑SiO 2 / NRL mixture; S300, GO‑SiO 2 / NRL mixed solution is poured into the open mill, and the masterbatch is obtained on the roller of the open mill, after the masterbatch is dried, the scraper on the roller is used to scrape the masterbatch and collect it for later use; S400, the prepared Masterbatch, zinc oxide ZnO, stearic acid SAD, accelerator DPG, antioxidant 4020 are mixed to complete GO‑SiO 2 The preparation of / NR composite materials avoids the accumulation of groups during the static spraying process, resulting in uneven molecular bonding in the masterbatch, and then the droplets are instantly dehydrated and dried to obtain GO‑SiO 2 / NR masterbatch, the process is simple and controllable, the principle is scientific and reasonable, the energy consumption and production cost are low, the operability is strong, the dispersion is more uniform, and the use environment is friendly.

Description

Technical field[0001]The present invention relates to the field of rubber kneading, in particular a method of preparing a GO / NR composite material and a manufacturing opening machine thereof.Background technique[0002]The mixing is the first step in the rubber processing process, and is also the most critical process. The various fillers are mixed with rubber through this process, and the filler is uniform as possible, and the quality of the mixing results directly determines the rubber article. The performance and service life have been prepared from the industry.[0003]The oxide oxide (GO) is a graphene derivative, which is a two-dimensional material having a carbon atomic hybrid type in the original graphite structure obtained by graphite; GO has a slight sheet structure, large The specific surface area contains a large amount of hydroxyl group, carboxyl group or the like, has excellent mechanical, thermodynamic and electrical properties. When these properties make the GO are add...
