Abstract
The invention discloses a novel low temperature and oil resistant flexible pipe. The flexible pipe comprises, by weight, 80-120 parts of PVC resin, 1.5-2.5 parts of barium stearate, 8.0-12.0 parts of dioctyl adipate, 35-45 parts of tritolyl phosphate and 0.5-1.5 parts of carbon black. Compared with flexible pipes in the invention, the novel low temperature and oil resistant flexible pipe produced in the invention has the advantages of low price, few used raw materials, simple production process, and stable oil resistance at a low temperature.
Description
Technical field
The present invention relates to material science, refer more particularly to a kind of novel anti-low temperature oil resistant flexible pipe and production method thereof.
Background technology
Oil resisting rubber hose, its feature is to have good acid resistance gasoline, the performance of ethanol-tolerant gasoline, and also also good to the stopping property of Water Oil Or Gas.The general oil-proofness of oil resisting rubber hose is in the market better, but cold resistance is not all right, under the environment of low temperature, cause the ability that dissolving, swelling, cracking, distortion or physicals reduce, and oil resistance also can be affected in various degree the in the situation that of low temperature, Given this situation, now study a kind of anti-low temperature oil resistant flexible pipe, can resist severe cold, and in severe cold, there is equally the novel anti-low temperature oil resistant flexible pipe of good oil resistance.
