Abstract

The invention provides a nano-microcrystalline NCC reinforced rubber material and a preparation method thereof. The nano-microcrystalline NCC reinforced rubber material is composed of NCC, chemical auxiliary agents, modifiers and EPDM rubber masterbatch. The preparation method comprises the following steps: 1) treating NCC with a surface active agent; 2) adding EPDM rubber masterbatch, modifier and modified NCC solution into a mixer for mixing; 3) mixing antiaging agent and mixing Put the mixing material into the internal mixer and add rubber vulcanizing agent after internal mixing, knead and stir at a high speed and then transport it to the open mill; 4) Thinly pass the mixture in the open mill to make the EPDM rubber masterbatch, modifier and modified NCC is fully mixed and uniform, input into the screw extruder, and the product is formed through the extruder and the extrusion die; 5) The extruded product is vulcanized, and the product is obtained after vulcanization. The material toughness and wear resistance of the invention are significantly increased, and the raw material cost is low, and the material is clean and environment-friendly.

Description

technical field [0001] The invention belongs to the field of rubber materials, and relates to a rubber material and a preparation method thereof, in particular to a nano-microcrystalline NCC reinforced rubber material and a preparation method thereof. Background technique [0002] As a high-quality elastic material, rubber has been widely used in various fields. According to the composition of rubber, its performance and use are also different. There are ordinary rubber flooring and anti-slip mats for general household floors, and special reinforced rubber gaskets for container sealing and flange sealing. Glass fiber, carbon fiber, aramid fiber, synthetic fiber, carbon black, etc. are usually used to reinforce rubber materials, which have the advantages of temperature and pressure resistance, good wear resistance, good solvent resistance, etc., but there are also many problems, such as fiber Uneven dispersion, weak bonding of rubber and fiber, etc., resulting in unsatisfact...
