Abstract
The invention discloses oil-resistant high-temperature-resistant acrylate rubber which is prepared from the following raw materials, by weight, 100 parts of acrylate rubber, 150 parts of soft carbon black, 5-6 parts of a plasticizer, 1-2 parts of an anti-aging agent, 6-8 parts of a demolding aid, 1-3 parts of stearate, 2-3 parts of a scorch retarder, 1-2 parts of a vulcanizing agent and 0.1-0.3 part of an improved co-vulcanizing agent; the preparation method of the oil-resistant high-temperature-resistant acrylate rubber comprises the following steps: adding acrylate rubber, soft carbon black, a plasticizer, an anti-aging agent, a demolding aid, stearate and a scorch retarder into an internal mixer in sequence, and carrying out pressure mixing; starting a cold mill, feeding the mixed rubber compound into an open mill to pass through a roller, fusing, then, cutting by a left cutter and a right cutter, packaging in a triangular bag, thinly passing, cooling, slicing, and storing for 24 hours; adding a vulcanizing agent and an improved auxiliary vulcanizing agent, exhausting for 3 times, and vulcanizing and forming to obtain the oil-resistant and high-temperature-resistant acrylate rubber.
Description
Technical Field
The invention belongs to the field of rubber production, and particularly relates to oil-resistant and high-temperature-resistant acrylate rubber and a preparation method thereof.
Background
The rubber has excellent performances such as good weather resistance, insulation property and inertia, and is widely applied to automobiles, households, cables, aviation and the like, the development application of the rubber product is continuously increased at present, and the rubber product is continuously developed according to the characteristic market potential. Although fluororubbers, nitrile silicone rubbers and the like are improved in oil resistance and heat resistance at present, the fluororubbers, the nitrile silicone rubbers and the like cannot be widely applied due to high production cost and technical requirements.
Patent No. CN102276953A the present invention relates to a composition of acrylate rubber and ethylene acrylate rubber.
