Abstract

The invention discloses an impregnated aramid rubber-based special material. The material comprises the following raw materials: aramid short fiber, natural rubber, carbon black, stearic acid, zinc oxide, accelerator, silicone powder, quartz powder, molybdenum disulfide and sulfur. The invention also discloses a method for preparing the material. The method comprises the following preparation steps: Step 1: shearing; Step 2: pretreatment; Step 3: irradiation grafting; Step 4: dipping rubber; Step 5: preparing mixed rubber; Step 6: preparing a semi-finished product of the impregnated aramid rubber-based special material; and Step 7: vulcanization. The material aims at solving technical problems of poor wear resistance, low mechanical strength and the like of an aramid fiber and rubber composite material in the prior art, and has advantages of improving wear resistance and mechanical strength of a composite material of aramid fiber and rubber.

Description

technical field [0001] The invention relates to the technical field of rubber composite materials, in particular to an impregnated aramid rubber-based special material and a preparation method thereof. Background technique [0002] Rubber composites are mostly composed of skeleton materials and elastic rubber matrix. Compared with thermosetting and thermoplastic polymer composites, rubber composites have a larger deformation range, higher load-bearing capacity and good fatigue resistance. In rubber In composite materials, the performance and service life of the skeleton material play a decisive role in the overall performance. The rubber composite materials in the prior art mostly use glass fiber, aramid fiber, carbon fiber, polyethylene fiber, etc. as the skeleton material. Among them, Aramid fiber is a kind of aramid fiber. The composite material of aramid fiber and rubber in the prior art has the problems of poor wear resistance and poor mechanical strength. [0003] Ai...
