Embodiment 1

[0024] Before the reaction, 80 parts of EPDM was dissolved in 60 parts of toluene. In a four-necked round bottom flask equipped with a stirrer, a condenser, a thermometer and an inert gas inlet tube, 0.05 parts of gelatin, tricalcium phosphate, and 0.025 parts of dodecyl were added. Sodium sulfate, 180 parts of deionized water, under the protection of nitrogen, heat up to 30°C in an oil bath, after 20 minutes of constant temperature, dissolve EPDM with toluene, 20 parts of 4-tert-butylstyrene, and 0.01 parts of divinylbenzene , 0.05 part of benzoyl peroxide was added to a four-necked flask, stirred at 400 rpm and then at 350 rpm under the protection of nitrogen, and reacted at 70°C for 6 hours. After the reaction is complete, the temperature is raised to 80°C for maturation 1 After hours, filter, wash with hydrochloric acid solution and deionized water three times successively, and dry in vacuum to obtain the resin. After measurement, the particle size is 0.5-1mm; the oil absorpti...

Embodiment 2

[0031] Before the reaction, 90 parts of polybutadiene rubber was dissolved in 360 parts of xylene. In a four-necked round bottom flask equipped with a stirrer, a condenser, a thermometer, and an inert gas inlet tube, 0.1 part of gelatin, tricalcium phosphate, and 0.05 were added. Parts of sodium lauryl sulfate, 1500 parts of deionized water, under the protection of nitrogen, heat up to 40°C in an oil bath, after 30 minutes of constant temperature, dissolve xylene in polybutadiene rubber, 10 parts of 4-tert-butyl Styrene, 3 parts of divinylbenzene, 0.05 part of benzoyl peroxide were added to a four-necked flask, and under the protection of nitrogen, the mixture was stirred at 380 rpm, then at 360 rpm, and reacted at 70°C for 8 hours, and so on. After completion, it was heated to 80°C for 1 hour, filtered, washed with hydrochloric acid solution and deionized water three times, and dried in vacuum to obtain the resin. The particle size was determined to be 0.5-1mm; The oil absorption...

Embodiment 3

[0039] Before the reaction, dissolve 50 parts of polyisobutylene in 200 parts of cyclohexane, and add 0.08 parts of methyl cellulose and 0.03 parts to a four-neck round bottom flask equipped with a stirrer, condenser, thermometer, and inert gas inlet tube. Calcium dodecylbenzene sulfonate, 1000 parts of deionized water, under the protection of nitrogen, heat up to 35℃ in an oil bath, after 25 minutes of constant temperature, dissolve the polyisobutylene in cyclohexane, 50 parts of 4-tert-butyl Styrene, 2 parts of divinylbenzene, 2 parts of benzoyl peroxide were added to a four-necked flask, and stirred at 380 rpm, then at 360 rpm under the protection of nitrogen, and reacted at 70°C for 7 hours, etc. After the reaction is completed, the temperature is raised to 80° C. for maturation for 1 hour, filtered, washed with hydrochloric acid solution and deionized water three times, and dried in vacuum to obtain the resin. The particle size is 0.5-2mm after measurement. The oil absorption...

Abstract

A rubber-based resin with high oil absorptivity is proportionally prepared from rubber, alkylstyrene, cross-linking agent, disperser, co-disperser, free radical polymerization trigger, dispersing medium and solvent through adding dispersing medium, disperser and co-disperser into flask, heating to 30-40 deg.C by oil bath under protection of inertial gas, keeping the temp for 20-30 min, adding others in 4-opening flask, variable-speed stirring, reacting, ageing, filtering, washing and vacuum drying.

Description

Technical field [0001] The invention relates to a high oil absorption resin and a preparation method thereof, in particular to a rubber-based high oil absorption resin and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of offshore oil exploration and development, the pollution of oceans, rivers, lakes, and groundwater caused by oil tankers, oil tanks, oil field leaks, oil pipeline accidents, and the discharge of oily wastewater and waste liquids has become increasingly serious. Causes extremely bad effects on human life, the ecological environment and economic development. Since oil pollution is extremely destructive to the ecology and the environment, it forces mankind to urgently need to develop a large number of excellent oil-absorbing materials whose de-oiling effect can change over time and oil. Product, oil pollution level, location and weather conditions. [0003] Super oil-absorbing resin is a new type of functional...
