Embodiment 1

[0055] After mixing 160 grams of bagasse fiber and 40 grams of tapioca starch evenly, add it into a reaction vessel with a capacity of 1 liter, then add 60 grams of sodium hydroxide solution with a mass concentration of 10%, stir evenly, and then add 20 grams of butyl acrylate The ester monomer and 1 gram of potassium persulfate were stirred evenly, placed in a microwave reactor with a working frequency of 80KHz and a power of 1000W, heated to 60°C and reacted for 50 minutes to obtain 223 grams of the oil-absorbing material of the present invention.

[0056] The applicant has carried out application experiment with above-mentioned oil-absorbing material, and its result sees figure 1 . from figure 1 It can be seen that the oil-absorbing material exhibited rapid adsorption capacity in the first 5 minutes of the test, and the speed decreased significantly after reaching a certain degree of saturation. Therefore, the test shows that the fast adsorption performance of this materi...

Embodiment 2

[0058] After mixing 100 grams of cassava stalk fiber and 100 grams of potato starch evenly, add it into a reaction vessel with a capacity of 1 liter, then add 40 grams of sodium hydroxide solution with a mass concentration of 80%, stir evenly, and then add 30 grams of Heptyl acrylate monomer and 2 grams of ammonium persulfate, after stirring evenly, heated up to 60°C under microwave reaction conditions of 80KHz working frequency and 1200W power, and reacted for 30 minutes to obtain 231 grams of the oil-absorbing material of the present invention .

Embodiment 3

[0060] After mixing 110 grams of cornstarch and 90 grams of cotton stalk fibers evenly, add them to a reaction vessel with a capacity of 1 liter, then add 200 grams of sodium hydroxide solution with a mass concentration of 30%, stir well, and then add 60 grams of methyl Cetyl acrylate monomer and 0.5 g of ceric sulfate, after stirring evenly, under the microwave reaction conditions of working frequency of 120KHz and power of 2000W, heated up to 50°C and reacted for 60 minutes to obtain the oil-absorbing material 265 of the present invention gram.

Abstract

The invention discloses a method for preparing a biodegradable oil absorption material, which comprises the following processing steps of: 1) mixing a mixture of fiber base material and starch and 10 to 80 mass percent sodium hydroxide solution in a mass ratio of 1:0.2-1; 2) adding acrylate monomer accounting for 10 to 30 percent of the total mass of the fiber base material and the starch and an initiator accounting for 0.1 to 2 percent of the total mass of the fiber base material and the starch, and uniformly blending; 3) placing the solution in a microwave reactor with the working frequency of 80 to 140 KHz and the power of 300 to 20,000W, raising the temperature to between 50 and 60 DEG C, and reacting for 20 to 60 minutes. The oil absorption material prepared by the method has excellent biodegradation performance and high-efficiency oil absorption performance, has small volume before oil absorption, and is convenient to store and transport. After oil absorption, oil cannot be leaked under the action of permitted external force. Under the condition that even if water is present, the oil absorption material can effectively absorb oil in an oil-water mixed system.

Description

technical field [0001] The invention relates to an oil-absorbing material, in particular to a preparation method of a biodegradable oil-absorbing material. Background technique [0002] The leakage, splashing, dripping and natural replacement of various oils during use and transportation will affect the work progress and pollute the environment, especially the negative impact on sensitive areas such as oceans, rivers, forests, farmland and mines. In particular, some oils such as crude oil and mineral-based lubricating oil have poor biodegradability in the natural environment and a long residence time, which will seriously damage the ecological environment and ecological balance; it also causes this non-renewable but indispensable resource for industry waste. To deal with all kinds of oil pollution on the water surface or soil, the use of oil-absorbing materials is the most common method. [0003] At present, there are two types of common oil-absorbing materials. One is che...
