Problems solved by technology

This kind of oil-absorbing material has the defects of slow oil absorption speed, low oil absorption, poor oil retention and few types of oil absorption.
Therefore, there are many inconveniences in actual operation. For example, the oil will be released into the environment again during the transportation and storage of the oil-absorbing material after absorbing the oil, causing secondary pollution.

Embodiment 1

[0030]Add 300 grams of styrene, 900 grams of stearyl acrylate and 20 grams of divinylbenzene into a four-liter container, then add 1900 grams of deionized water and 10.25 grams of tricalcium phosphate, mix well and heat to 55°C , When this temperature is reached, dissolve 0.021 grams of potassium persulfate in 50 grams of deionized water, add to the mixture, mix well and heat to 85 ° C, then add 2.73 grams of benzoyl peroxide, 0.989 grams of tert-amyl peroxide - 2-Ethyl acetate and 1.16 grams of dicumyl peroxide and 64 grams of styrene monomer are evenly mixed with each other, and then added to the mixed solution to react for about 6 hours. After the reaction is complete, add 1.82 grams of 3% cyclohexyl (meth)acrylate and 150 ml of water into the mixture, heat the mixture to 114°C and keep it at 114°C for about two hours, then cool the reaction mixture to 60°C. and acidified with 42.5 ml HCl. The resultant particulate polymer was then screened out with a polymer sieve, and t...

Embodiment 2

[0032] The granular polymers obtained in Example 1 were rolled by passing them through steel rollers with a gap of 0.5 mm. The granular polymer will be deformed due to extrusion between the rollers. When the granular polymer is not crushed, a large number of cracks will appear on the outer surface of the granular polymer, which will increase its oil absorption effect.

Embodiment 3

[0034] Add 280 grams of vinyl butyrate, 2000 grams of p-propyl ethylene and 20 grams of diacrylate into a four-liter container, then add 1500 grams of deionized water and 14 grams of magnesium sulfate, mix well and heat to 40 ℃, when this temperature is reached, dissolve 0.045 g of dicumyl peroxide in 70 g of deionized water, add it into the mixture, mix well and heat to 95 °C, and then add 1.05 g of tert-amyl peroxide-2-ethyl Diethyl acetate and 1.2 grams of tert-amyl peroxide-2-ethyl acetate were dissolved in 80 grams of styrene monomer, and 79 grams of liquid butane was added to the mixed reaction system, and the suspension polymerization was carried out for about 4 hours, and then The reaction mixture was cooled to 30°C. and acidified with 50 mL of HCl. Then use a polymer sieve to screen out the polymer containing low-boiling butane particles. Then, the particle polymer pellets are evaporated at a temperature of 98° C. and a vapor pressure of 0.1 Mp to obtain an oil-abso...

Abstract

The invention discloses a preparation method of an oil-absorbing material. According to the invention, a monomer A, water and a cross-linking agent are subjected to a suspension polymerization reaction under the effect of an initiator and a dispersant, and produced polymer particles are separated by screening. The monomer A is composed by one or more components selected from acrylic ester, vinyl ester, and styrene monomer organics. The cross-linking agent is composed of olefin ester or olefin containing two or more unsaturated carbon-carbon double bonds. The oil-absorbing material prepared from the method and the raw materials is advantaged in high oil absorption speed, and good oil retaining performance. Oil absorbed into the oil-absorbing material is prevented from being released into the environment during transportation and storage processes, such that secondary pollution is prevented. The oil-absorbing material with the absorbed oil can be used as furnace or boiler fuel for combustion. The preparation method is simple, and the operation is simple.

Description

technical field [0001] The invention relates to the field of materials, in particular to a preparation method of an oil-absorbing material. Background technique [0002] Oily sewage, waste liquid discharge and leakage from oil tankers and oil tanks will all cause serious pollution to the environment. At present, most of the treatment of these pollution sources is to absorb the slick oil through oil-absorbing materials to achieve the purification of the pollution sources. Traditional oil-absorbing materials are mostly inorganic and organic materials that are modified, mixed, and pressed by physical methods. According to their oil-absorbing mechanism, they can be divided into occlusion-type oil-absorbing materials, gel-type oil-absorbing materials, and occlusion-gel composite oil-absorbing materials. , this type of oil-absorbing material absorbs oil by using the capillary force of its surface, gap and cavity and / or utilizes the physical cohesion between molecules or substance...
