Problems solved by technology

However, the oil absorption rate of the oil-absorbing materials currently developed is still not high, the oil absorption rate is slow, the reversibility of oil absorption and discharge is poor, and the stability and anti-aging performance are poor, and the service life is short.
The application number is CN201410088794.1, which discloses a butyl rubber composite gel oil-absorbing material and its preparation method, using butyl rubber as the base material, disulfide dichloride as the crosslinking agent, octylphenol formaldehyde resin and p-benzoquinone Dioxime is used as an accelerator to form a three-dimensional network space structure. The obtained oil-absorbing material has low density, large oil absorption capacity, fast adsorption rate and can absorb various oil products. It can be recycled many times after simple extrusion treatment, effectively It is a new type of environmentally friendly material, but the service life of this oil-absorbing rubber is still short, and the oil absorption is also insufficient, which cannot meet the needs of today's society

Abstract

The invention discloses oil absorption rubber with good stability, relating to the chemical field of rubber. The oil absorption rubber is prepared from the following raw materials in parts by weight: 95-110 parts of base rubber, 1-3 parts of oil absorption resin, 1-3 parts of carbon black N550, 2-6 parts of stearic acid, 2-6 parts of naphthenic oil, 1-4 parts of zinc oxide, 0.5-1.5 parts of an anti-aging agent, 1-3 parts of calcium oxide, 0.5-1.0 part of an accelerating agent and 0.4-1.2 parts of a vulcanizing agent. The invention also discloses a preparation method of oil absorption rubber with good stability. By optimizing the proportions of all components and adding a special modifying agent, on the basis of the original rubber, the oil absorption performance is further increased, high oil absorption efficiency is ensured while the oil absorption rate, stability and ageing resistance are increased, the service life is prolonged, environmental resources are saved, the environmental friendliness is good, the preparation method is simple, the oil absorption rubber can be used for absorption of crude oil, gasoline, swill-cooked dirty oil, lubricating oil and mechanical waste oil, and application prospects are wide.

Description

technical field [0001] The invention relates to the field of rubber chemical industry, in particular to an oil-absorbing rubber with good stability and a preparation method for the oil-absorbing rubber with good stability. Background technique [0002] In recent years, with the increasing frequency of human activities, a series of accidents such as oil field spills, oil spills from oil tankers, oil pipeline ruptures, and the discharge of oily waste water have caused serious water pollution, bringing immeasurable ecological disasters and Economic losses, such as the US Gulf of Mexico and my country's Bohai Bay oil spills. Therefore, there is an urgent need for human beings to develop low-cost, super oil-absorbing materials with super-high oil absorption capacity, so that they can quickly treat oil pollution on water surfaces in harsh environments. [0003] The highly oil-absorbing materials currently studied are often low-crosslinked polymers, which use lipophilic monomers as...
