Abstract

The invention discloses a PVC hose formula being high in oil resistance. The PVC hose formula comprises the following raw materials in parts by mass: 95-100 parts of PVC resin, 1-3 parts of dibutyl tin dialurate, 0.1-0.2 part of barium stearate, 0.4-0.6 part of cadmium stearate, 8-10 parts of dioctyl adipate, 10-15 parts of butadiene-acrylonitrile rubber, 4-6 parts of epoxy soybean oil, and 22-25parts of tricresyl phosphate. The barium stearate is used as an internal lubrication agent, the cadmium stearate can be used as a heat stabilizer, and besides, the tricresyl phosphate is added to thePVC hose formula, so that the entire oil resistance can be improved; besides, the butadiene-acrylonitrile rubber is added, so that the entire oil resistance can also be improved; the dioctyl adipate is added, so that the low-temperature properties of the hose can be improved, and the service life of the PVC hose under oil environment can be prolonged.

Description

technical field [0001] The invention relates to a PVC hose formula with good oil resistance, which is applied in the field of plastic formula modification. Background technique [0002] The main component of PVC is polyvinyl chloride, which is a popular, popular and widely used synthetic material in the world today. It is the second most used synthetic material worldwide. PVC hose is a new type of pipe material. At present, PVC hoses on the market have the defect of poor oil resistance, that is, PVC hoses have poor resistance to oil-induced dissolution, swelling, cracking, deformation, or physical performance reduction. Some recipes have been improved. Contents of the invention [0003] Aiming at the above technical problems, the invention discloses a PVC hose formula with good oil resistance, which has the advantages of good oil resistance and long service life. [0004] The invention discloses a PVC hose formula with good oil resistance, which consists of the followin...
