Description
Technical Field
The invention belongs to the field of chemical industry, and particularly relates to a preparation method of resin and application of a product thereof.
Background
With the rapid development of industry, environmental pollution caused by leakage accidents of oil ships and oil tanks and the discharge of oily industrial wastewater is attracted by people, and the traditional oil absorption material has the defects of low oil absorption multiplying power, poor oil-water selectivity, low oil retention rate and the like, so that the development of a green and efficient oil stain scavenger becomes a hot topic of research.
The synthesis of the high oil absorption resin has 2 directions, namely the high oil absorption resin is synthesized by pure monomers or is synthesized by modifying natural and synthetic macromolecules. The pure monomer synthesis method is widely researched at home and abroad due to the abundant monomer types, and the modified synthesis method is more and more favored by people due to the utilization of renewable natural polymers. The modification synthesis method comprises 2 methods that firstly, 2 monomers react to generate an intermediate product, then the intermediate product reacts with a 3 rd monomer to generate high oil absorption resin, and secondly, small molecules are grafted on macromolecules to improve the oil absorption performance of the high oil absorption resin. For example, Ma Shi Chen et al take cellulose and sebacic acid as raw materials, toluene as a solvent and p-toluenesulfonic acid as a catalyst to perform esterification reaction, the reaction product is subjected to secondary esterification with n-butanol, and the oil absorption multiplying power of the obtained modified high oil-absorbing resin on gasoline is 15 (Ma Shi Chen, Song Hui, Wang Chun Qiao, etc.. the process conditions and oil absorption effect of the modified cellulose for synthesizing the high oil-absorbing resin [ J ] proceedings of the university of Ligusticum chuanglian academy of industry, 2003, 22(4): 256-258.). The long-chain acrylate is grafted on cotton linter by Cao sub-peak and the like, the oil absorption rate of the grafted oil-absorbing resin is different along with the change of the number of carbon atoms, when the grafted monomer is octyl acrylate and the mass ratio of the polymer substrate to the monomer is 60, the maximum oil absorption rate of the grafted and synthesized high-oil-absorbing resin is 16 (Cao sub-peak, Liu Mey, Han Xue, and the like.
The inventor finds that the oil-absorbing resin mainly has the following problems in oil stain treatment:
(1) the oil absorption rate is high, but the preparation method is complex and the production cost is high;
(2) the function is single, the adsorption performance to specific oil stains is high, and the popularization range is narrow;
(3) the oil absorption and oil retention rate are high, but the recovery rate of the waste oil is low, and the waste oil is difficult to recycle.
Disclosure of Invention
In order to solve the problems, the invention provides a preparation method of resin and application of a product thereof. The high oil absorption resin has the advantages of simple method, low raw material cost and low production cost; the obtained oil-absorbing resin has excellent performance.
The invention adopts the following technical scheme:
in a first aspect of the present invention, there is provided a method for preparing a resin, comprising the steps of:
(1) carrying out microwave pretreatment on the plant fiber;
(2) weighing deionized water, azobisisobutyronitrile, N' -methylene bisacrylamide and sodium dodecyl benzene sulfonate according to the weight parts, and dispersing for 20-30 min by using ultrasonic to obtain a mixed solution;
(3) and (3) adding the plant fiber pretreated in the step (1) and alkyl methacrylate into the mixed solution prepared in the step (2), magnetically stirring, introducing nitrogen for protection, and reacting for 3-8 hours at 65-80 ℃.
In a second aspect of the present invention, there is provided a resin prepared by the above-described preparation method.
The resin of the third aspect of the invention is applied to the treatment of oil-contaminated wastewater.
Further, the application in adsorbing kerosene, gasoline and diesel oil.
In a fourth aspect of the invention, the resin is applied to normal hexane adsorption and desorption.
In a fifth aspect of the invention, there is provided an n-hexane adsorbent comprising the resin described above.

after the resin is modified by the plant fiber, the oil absorption rate and the oil retention rate are both greatly improved. The resin prepared by the invention not only has high adsorption rate and oil retention rate to petroleum products such as kerosene and the like, but also is easy to desorb and recover waste oil products; the desorbed resin can be continuously recycled. In addition, the invention has surprisingly found that the resin not only has high adsorption performance on petroleum products, but also has an adsorption rate on n-hexane of 825 mg/g.
The high oil absorption resin has simple preparation method and low production cost, and can be used for large-scale production.

As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of the stated features, steps, operations, and/or combinations thereof, unless the context clearly indicates otherwise.
In view of the problems of the oil-absorbing resin in the background art, the first aspect of the present invention provides a method for preparing a resin, comprising the following steps:
(1) carrying out microwave pretreatment on the plant fiber;
(2) weighing deionized water, azobisisobutyronitrile, N' -methylene bisacrylamide and sodium dodecyl benzene sulfonate according to the weight parts, and dispersing for 20-30 min by using ultrasonic to obtain a mixed solution;
(3) and (3) adding the plant fiber pretreated in the step (1) and alkyl methacrylate into the mixed solution prepared in the step (2), magnetically stirring, introducing nitrogen for protection, and reacting for 3-8 hours at 65-80 ℃.
The plant fiber is added into the resin system, on one hand, the addition of the plant fiber is beneficial to the formability and the pore-forming property of the oil-absorbing resin to improve the strength of the oil-absorbing resin, on the other hand, the plant fiber or the protein structure contains a large number of hydrophilic and oleophilic groups such as hydroxyl and the like, has certain surface activity and can replace alkylphenol emulsifying and dispersing agents (OP-10 and the like) which are easy to generate formaldehyde in the traditional combustion process, and the plant fiber can play the aims of emulsifying and dispersing and can improve the safety of solid fuel under the synergistic action of the plant fiber and sodium dodecyl benzene sulfonate.
Further, the microwave pretreatment conditions are as follows: the heating power is 300-400W, and the heating time is 30-90 s. The plant fiber is subjected to microwave pretreatment, chemical bonds in the plant fiber can be opened through microwave heating, more hydrophilic and lipophilic groups are exposed, and the activity of the plant fiber is improved. The microwave heating power and the heating time have great influence on the improvement of the fiber activity, and the microwave heating power and the heating time are too low and short, so that the microwave heating power and the microwave heating time hardly have the effect of improving the activity of the plant fiber; if the power is too high and the time is too long, the original plant fiber structure can be thoroughly changed, and the function of the original fiber is changed. Within the range of the treatment condition of the invention, the activity improvement effect on the plant fiber is obvious.
Further, the weight parts of the raw materials used in the steps are as follows: 100 portions of deionized water, 150 portions of azodiisobutyronitrile, 0.01 to 1 portion of N, N' -methylene bisacrylamide, 0.01 to 0.06 portion of sodium dodecyl benzene sulfonate, 10 to 100 portions of alkyl methacrylate and 1 to 10 portions of plant fiber. The performance of the finally prepared resin can be influenced by the dosage of each component, and the performance of the prepared resin is stable within the dosage range of each raw material.
Further, the plant fiber is soybean dietary fiber. The soybean dietary fiber has high water-holding and oil-holding capacity, can adsorb a large amount of water and oil, cannot cause collapse and deformation of a product due to dehydration, contains protein, can adsorb a large amount of oil, and can improve the oil absorption performance of the oil-absorbing resin.
Further, the alkyl methacrylate may be lauryl methacrylate.
In a second aspect of the present invention, there is provided a resin prepared by the above-described preparation method. The resin provided by the invention is simple in preparation method, has good oil absorption performance, and is renewable and practical.
The resin of the third aspect of the invention is applied to the treatment of oil-contaminated wastewater.
