preparation example Construction
[0058] A preparation method for a high and low temperature resistant EPDM V-belt, comprising the following steps:
[0059] (1) Preparation of materials;
[0060] (2), masticating EPDM rubber for 3-5 minutes, the masticating temperature is 50-60°C;
[0061] (3), then add promotor, zinc oxide, antioxidant and carry out mixing 2-8 minute;
[0062] (4), then add carbon black, paraffin oil, peroxide cross-linking agent and continue mixing for 2-5 minutes;
[0063] (5) Finally, add cotton powder and nylon, and knead for 3-5 minutes to produce glue.
[0064] Through the above method, the production efficiency is high and the comprehensive performance is good.

Abstract
The invention discloses a high and low temperature resistant EPDM V-belt, the glass transition temperature of which is -60°C, and its unsaturation is very low, it can be used for a long time at a temperature of 120°C, and its maximum service temperature is 150°C, the fatigue performance is also very good, the main point of the technical solution is to include the primer, the formulation of the primer includes the following components by weight: 100 parts of EPDM rubber; 6-10 parts of accelerator; 4-6 parts of zinc; 2-5 parts of anti-aging agent; 50-70 parts of carbon black; 3-8 parts of paraffin oil; 5-8 parts of peroxide crosslinking agent; 10-20 parts of cotton powder; 5-15 parts of nylon , the present invention is applicable to the field of V-belt technology.
Description
technical field [0001] The invention belongs to the technical field of V-belts, in particular to a high-low temperature resistant EPDM V-belt and a preparation method thereof. Background technique [0002] Rubber V-belts are important spare parts in modern industrial production equipment. Rubber V-belts are wrapped V-belts and trimmed V-belts, and V-belts are friction transmission. V-belts are also used in a wide range of fields, such as automotive V-belts, motorcycle variable-speed V-belts, agricultural machinery variable-speed V-belts, etc. It is also used in a variety of working conditions, including high loads. In high load environments, the belt is driven by friction and the temperature rises very high. Then in the high cold area, such as below minus 40 ℃, some rubber will become brittle. For example, the neoprene rubber that we usually use in the production of V-belts has excellent fatigue performance, but the operating temperature range is -30 to 90°C, and both high...
