Abstract

The invention provides a preparation method of a high-efficiency oil suction rubber material. The preparation method comprises the following steps: modifying natural rubber to obtain modified naturalrubber; modifying guayule rubber to obtain modified guayule rubber; modifying the modified natural rubber, modified guayule rubber, modified oyster shell powder, naphthenic oil, zinc oxide, stearic acid, an antioxidant PPD, disulfur dichloride and an accelerator TBBS, and adding the obtained mixture into an internal mixer, and mixing the mixture; processing the mixed mixture between an upper sheetand a lower sheet of a two-roll mill to form a rubber sheet have a thickness of 4 mm; uniformly lying the rubber sheet in a low-temperature plasma treatment device, and treating the rubber sheet; taking out the treated rubber sheet, and foaming the rubber sheet in an autoclave of a supercritical carbon dioxide foaming device; placing the foamed rubber sheet in an air dry oven, vulcanizing the foamed rubber sheet at 150-155 DEG C for 20-30 min, heating the rubber sheet to 170 DEG C, and carrying out heat treatment for 3 h; immersing the rubber sheet in a fluorine-free waterproof agent NT-X018;and taking out the rubber sheet, and drying the rubber sheet in a drying box to obtain the high-efficiency oil suction rubber material. The high-efficiency oil suction rubber material prepared by themethod has a very good oil suction effect.

Description

technical field [0001] The invention relates to a preparation method of a high-efficiency oil-absorbing rubber material. Background technique [0002] Oil-absorbing materials have experienced the development process from traditional oil-absorbing materials to high-efficiency oil-absorbing materials. At present, the oil-absorbing materials used in my country are mainly traditional oil-absorbing materials, such as corn stalks, non-woven wool, kapok fiber, vermiculite, expanded graphite, zeolite, etc. However, these traditional oil-absorbing materials mainly rely on physical adsorption to absorb oil on the surface of the material or in the internal capillary. Its application in oil-water mixed system. High-efficiency oil-absorbing materials are different from traditional oil-absorbing materials. They are new high-performance functional materials. At present, there are many researches: rubber-based oil-absorbing materials prepared by processing or polymerizing methods; acrylat...
