Embodiment

[0028] The preparation method using the low temperature resistance, grease resistance and high temperature resistance rubber composition disclosed by the present invention comprises the following steps:

[0029] 1. Take the nitrile rubber of the formula amount, and add the formula amount of magnesium oxide, zinc oxide, stearic acid, magnesium methacrylate in turn after passing through the thin pass to be wrapped; then add half of the formula amount of carbon black; then add the formula in turn Amount of flow aid WB222, anti-aging agent 445 and ZMMBI, plasticizer; then add half of the formula amount of carbon black; finally add dicumyl peroxide, tetramethylthiuram disulfide, 4-4'-di Dimorpholine sulfide;

[0030] 2. Kneading the mixture processed in step 1;

[0031] 3. Place the mixture treated in step 2 for one day.

[0032] A rubber composition resistant to low temperature, grease and high temperature has been prepared, and its specific ratio is as follows:

Abstract

The invention discloses a rubber composition with low temperature resistance, grease resistance and high temperature resistance, a preparation method, a use and an application product thereof. The composition is prepared by the following raw materials: 100 parts of nitrile rubber, 1-35 parts of an active agent, 1-150 parts of carbon black, 1-5 parts of a reinforcing agent, 20-50 parts of plasticizer, 1-5 parts of a flow promotor, 1-10 parts of anti-aging agent, 1-5 parts of dicumyl peroxide, 1-3 parts of tetramethyl thiuram disulfide, and 1-5 parts of 4-4'-dithiodimorpholine. The rubber composition has three characters of the low temperature resistance, grease resistance and high temperature resistance on the basis of the good characters of the pure nitrile rubber, the production process is simple, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of artificial rubber, and relates to a rubber composition resistant to low temperature, grease and high temperature, a preparation method, use and application products thereof. Background technique [0002] Long-term contact between railway oil seal products and Ronex MP grease requires rubber products to have excellent oil resistance. At the same time, our country has a vast territory. In the northeast region of our country, railway transportation will encounter extremely cold weather, and rubber products are required to have low temperature resistance. However, in the southern part of my country, the climate is hot, and when the locomotive is running continuously, the sealing part of the oil seal will generate a lot of heat due to motion friction, and the rubber products are required to be resistant to high temperature and aging. [0003] Faced with this situation, there is a need for a railway oil seal p...
