Problems solved by technology

However, dispersants are often highly toxic, and when the oil spill area is large, the oil removal efficiency is not high
The second is that the coagulation method uses an oil coagulant to rapidly increase the viscosity of the oil, making the slick oil agglomerate, which is convenient for recycling. The coagulation method is not as common as the dispersion method, because the production process is complicated, the cost is high, and the recovery is difficult.
The innovation of the preparation method of the present invention is to adopt low-cost industrial raw materials polypropylene, polyethylene, polyethylene terephthalate and waste plastics to recycle the gained polypropylene, polyethylene, polyethylene terephthalate, through The fiber prepared by this method is used as an oil-absorbing material, which overcomes the disadvantages of high cost and complicated process for preparing oil-absorbing materials

Embodiment 1

[0033] Industrial raw material high-density polyethylene with a molecular weight of 300,000 is used. Through the horizontal disc centrifugal spinning equipment, the polyethylene fiber is made by the horizontal disc centrifugal spinning method.

[0034] In this embodiment, the process of making polyethylene fibers by horizontal disk centrifugal spinning method is that polyethylene raw materials flow into the center of the horizontal rotating disk in a molten or solution state, and are centrifuged by the heated rotating disk. The body or solution becomes filaments, and after cooling treatment, polyethylene fibers are finally formed. Wherein, the melting temperature is 160° C., and the rotation speed is 2000 rpm. The rotation speed of the turntable in the present invention ranges from 0 to 20,000 revolutions per minute, and when the rotation speed is 2000 revolutions per minute, the oil absorption rate of the prepared oil-absorbing material is relatively high.

[0035] The proc...

Embodiment 2

[0038] Other steps are with embodiment 1. The process of measuring the oil absorption rate is to weigh 0.5 grams of polyethylene fiber, put the polyethylene fiber into light diesel oil B (25°C, kinematic viscosity is 5.4cst) and let it stand for a few minutes, then pick it up and measure the oil absorption of the polyethylene fiber. The mass, and then calculate the oil absorption rate according to the formula.

[0039] The measured oil absorption was 11.8.

Embodiment 3

[0041] Other steps are with embodiment 1. The process of measuring the oil absorption rate is to weigh 0.5 grams of polyethylene fiber, put the polyethylene fiber into lubricating oil (25°C, kinematic viscosity is 342cst) and let it stand for a few minutes, then pick it up and measure the oil absorption of the polyethylene fiber. mass, and then calculate the oil absorption rate according to the formula.

[0042] The measured oil absorption was 16.8.

Abstract

The invention relates to the field of chemical industry, and discloses a method for preparing a polymer oil absorption material. The method comprises the following steps of: heating to melt raw materials so as to obtain a melt by a horizontal disc rotary centrifugal spinning method, and slowly putting the melt into the center of a turntable of a horizontal disc rotary centrifuge, which rotates at high speed, to generate silk, namely the polymer oil absorption material. By the method, low-cost raw materials are adopted, the preparation process is simple, and the prepared oil absorption material has high selectivity and oil absorption efficiency and a wide industrial application prospect.

Description

technical field [0001] The invention relates to a method for preparing polymer materials in the chemical industry, in particular to a method for preparing high-efficiency oil-absorbing fibers. The prepared oil-absorbing fibers can be used to absorb spilled oil on the ocean, edible oil for household use, and waste water discharged from domestic or industrial use. of oil. Background technique [0002] In recent years, the environmental pollution problems caused by frequent oil tanker and oil tank leakage incidents are attracting a lot of attention. On April 20, 2010, the oil drilling platform "Deepwater Horizon" leased by BP, owned by Transocean, which was operating 130 miles southeast of New Orleans in the United States, exploded and caught fire. On April 22, the drilling platform sank into the Gulf of Mexico, and a large amount of oil subsequently leaked into the sea. Since the accident, the leaked crude oil is estimated to be 3.5 million gallons (approximately 13.2475 mil...
