Problems solved by technology

Although the rubber material prepared by this method can improve the self-lubricating properties of ethylene-propylene rubber, a single lubricant that can be precipitated on the surface of the rubber is used. When the rubber friction wears out the lubricant, the rubber raw material will be directly worn , causing rubber parts to fail

preparation example Construction

[0039] The preparation method of described rubber material, comprises the steps:

[0040] The first step is to set the initial temperature of the internal mixer to 90°C and the rotational speed to 70r / min. First, add EPDM rubber, nitrile rubber, zinc methacrylate and carbon nanotubes. After banburying for 5 minutes, the modified Add neutral white carbon black, banbury for 2 minutes, finally add zinc oxide, accelerator, anti-aging agent, paraffin and lubricant, continue banburying for 3 minutes, and then discharge glue;

[0041] The second step is to set the roll distance of the open mill to 1mm, the roll temperature to 50°C, and the roll speed to 20r / min, wrap the rubber material after banbury mixing on the open mill, add sulfur after wrapping, and then use The "left and right three knives" method is used to knead it evenly, adjust the roller distance to 0.2mm, and then make a triangular bag 6 times, and then adjust the roller distance to 1.6mm to exhaust the film, and the fil...

Abstract

The invention discloses a self-lubricated wearing-resistant rubber material which is prepared from the following raw materials in parts by weight: 60-80 parts of ethylene-propylene-diene monomer rubber, 20-30 parts of nitrile rubber, 4-5 parts of zinc methacrylate, 2-3 parts of carbon nanotubes, 30-40 parts of modified white carbon black, 4-5 parts of zinc oxide, 1-2 parts of sulfur, 2-3 parts of accelerant, 1-2 parts of an anti-aging agent, 1-2 parts of paraffin and 10-11 parts of a lubricant. The invention further discloses a preparation method of the rubber material. Commixed rubber of the ethylene-propylene-diene monomer rubber and the nitrile rubber is adopted as a rubber matrix, and the zinc methacrylate and the carbon nanotubes are adopted as assistant crosslinkers, so that the rubber matrix with excellent properties can be obtained; due to adoption of the modified white carbon black, mechanical properties and the abrasion damage resistance of the rubber material can be improved; due to adoption of the lubricant, the rubber material has excellent self-lubricating performance, after a lubricant TP16 migrated to a surface is abraded, a lamellar structure, which is very liable to slide and move, of molybdenum disulfide plays a very good role of abrasion reduction, and thus the rubber material can be further protected.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to a self-lubricating wear-resistant rubber material and a preparation method thereof. Background technique [0002] Rubber materials are highly elastic polymer materials with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is divided into rubber and synthetic rubber. Synthetic rubber is used in different environments and has the conditions to adapt to the working environment. EPDM terpolymer is a terpolymer of ethylene, propylene and non-conjugated diene. It has good heat resistance, water resistance and weather resistance. This rubber product is used in automotive wiring harnesses. During threading and installation, It is required that rubber products are easy to install in sheet metal and have a low coefficient of fri...
