Abstract
The invention discloses sealing rubber for a heater. The sealing rubber is prepared from the following ingredients in parts by weight: 100 parts of fluorine rubber, 15-30 parts of polytetrafluoroethylene, 5-10 parts of magnesia, 0.6-1 part of sodium stearate and 0.02-0.05 part of sulfur. According to a preparation method of the sealing rubber for the heater, fluorine rubber and polytetrafluoroethylene are adopted as main materials, so that the sealing rubber has a very good sealing effect while excellent high temperature resistance is guaranteed, and the use performance of a product is improved. The sealing rubber for the heater, prepared by the preparation method, has very good high temperature resistance, and the use temperature can reach 400-450 DEG C. By adopting the formula of the sealing rubber, production resources of enterprises can be saved greatly, and the production cost for the enterprises is reduced.
