Problems solved by technology

The most traditional reinforcing agents in the rubber industry have always been carbon black and white carbon black. Although they have a certain reinforcing effect, both of these two reinforcing agents have very low apparent densities. When they are added to rubber, they are easily produced. Feiyang, heavy processing pollution, long processing time, high energy consumption for mixing, and the carbon black reinforced product is a single black color, and these two reinforcing agents are difficult to endow the product with higher hardness and better air resistance sex etc.
[0003] Graphite is a layered material with excellent lubricating properties and a very high shape factor in the exfoliated state. Graphite is one of the materials with the highest specific strength and has unique functional properties such as electrical conductivity and thermal conductivity. And the cost is low. As a reinforcing material for rubber, it can improve its tribological properties. However, due to the inert nature of the graphite material itself and the Van der Waals force between the layers, directly adding it to the rubber will greatly reduce its mechanical properties and shorten the service life.

The invention discloses a high temperature resistance rubber material for vehicles, which is prepared through raw materials with parts by weight: polyacrylonitrile 24-27, graphite 12-13, coal ash microspheres 3-4, lauryl sodium sulfate 0.7-1, liquid acrylonitrile butadiene rubber 42-55, methacrylic acids 0.6-1, nitrile rubbers 52-60, butadiene styrene rubber 20-25, colemanite 17-20, benzoyl peroxide 0.4-0.6, vulcanizing agent N,N'-m-phenylenedimaleimide (PDM) 2-3, liquid paraffin 2-3, an anti-aging agent D1-2, double fourteen carbon alcohol esters 1-2, clays 13-15, pyrophyllite in powder 7-8 and magnesium stearate 1-2. The high temperature resistance rubber material for the vehicles is excellent in high temperature resistance, cheap in raw materials, low in production cost and strong in practicality, has excellent application prospect when being used for the vehicles, and is simple in preparation method and easy for industrialization.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a high-temperature-resistant rubber material for automobiles. Background technique [0002] Rubber material is a polymer material that can quickly recover from deformation under large deformation. It is one of the important basic industries of the national economy. It provides light industrial rubber products for daily use and medical use that are indispensable in people's daily life; for mining , Transportation, construction, machinery, electronics and other heavy industries and emerging industries provide a variety of rubber production equipment or rubber parts, which are widely used. In recent years, the rapid development of the rubber industry has put forward higher requirements for rubber products, and rubber materials must develop in the direction of functionalization, refinement and diversification. The traditional single rubber material can no longer fully meet the rapidl...
