Abstract
The invention relates to a low temperature resistant rubber sealing part material which comprises the following rubber raw material components in parts by weight: 60-80 parts of N250S, 20-40 parts of N230S, 3-9 parts of stearic acid, 3-7 parts of a vulcanizing agent, 4-10 parts of high temperature ground carbon black, 6-9 parts of a plasticizing agent and 0.5-0.8 part of zinc oxide. The low temperature resistant rubber sealing part material has the benefits that through reasonable control of the content of acrylonitrile, and through the adoption of both the N230S acrylonitrile and N250S acrylonitrile, the low temperature resistance, the high temperature resistance and the oil resistance are obviously improved; a vulcanization system adopts a peroxide vulcanization system, the tensile strength of the rubber is high, the elastic resilience is excellent, the compression permanent deformation is less, and the high/low temperature resistance is excellent; a rubber reinforcing system adopts highly wear-resistant carbon black and spraying carbon black simultaneously, the physical and mechanical properties of the rubber are excellent, and the compression permanent deformation is less.
Description
Technical field
The present invention relates to sealing member technical field, be specifically related to a kind of cold resistant rubber sealing member material.
Background technology
Due to northern market cold in winter, outdoor environment can reach-40 DEG C, causes body of rubber material embrittlement, loses rebound resilience, causes sealing member leakage of oil.
NBR is by divinyl and acrylonitrile compolymer and a kind of synthetic rubber making, oil resistance excellence.The height of acrylonitrile content determines the effect of this rubber high-low temperature resistant and oil resistant quality: the low NBR resistance to low temperature of the fine content of propylene excellence, and high-temperature behavior declines, and oil resistance declines; Otherwise the high NBR resistance to low temperature of the fine content of propylene variation, high-temperature behavior excellence, oil resistance rises.
The height that is directed to acrylonitrile content determines this rubber high-low temperature resistant and oil resistant quality, needs the rational rubber seal formula of the design fine content of a kind of propylene to solve this problem.
