Problems solved by technology

Although the conventionally used oil-absorbing materials such as non-woven fabrics, oil-absorbing felts, and sponges are cheap, they have low oil absorption capacity, slow oil absorption speed, and poor oil absorption and retention effects, which are difficult to meet the needs of use.
Although traditional natural organic materials are easy to obtain raw materials, low cost, and safe to operate, they have small oil absorption and poor recycling rate
Other oil-absorbing materials are either expensive or complicated to prepare

Embodiment 1

[0053] In this example, a single-layer polypropylene microporous membrane with a thickness of 40 μm, a porosity of 75%, and an average pore diameter of 45 nm was prepared by the melt stretching method as a petroleum oil-absorbing material.

[0054] Among them, the single-layer polypropylene microporous membrane is prepared by Shenzhen Zhongxing New Material Technology Co., Ltd. according to the battery separator production process. After testing, the air permeability of the polypropylene microporous membrane in this example is 220s / 100mL, and the water contact angle is 97.5°. The air permeability and thickness are tested by the method in GB / T36363-2018, and the water contact angle is tested by the method in GB / T30693-2014. Each sample is tested 5 times and the average value is taken.

[0055] In addition, the tensile strength, puncture strength and oil absorption tests were carried out on the polypropylene microporous membrane used as the petroleum oil absorbing material in th...

Embodiment 2

[0058] In this example, a three-layer polypropylene microporous membrane with a thickness of 20 μm, a porosity of 45%, and an average pore diameter of 33 nm was prepared by the melt stretching method as a petroleum oil-absorbing material.

[0059] Among them, the three-layer polypropylene microporous membrane is prepared by Shenzhen Zhongxing New Materials Technology Co., Ltd. according to the battery separator production process. After testing, the air permeability of the three-layer polypropylene microporous membrane in this example is 250s / 100mL, and the water contact angle is 106.2°. Test method is the same as embodiment 1.

[0060] According to the method of Example 1, the tensile strength, puncture strength and oil absorption were tested for the three-layer polypropylene microporous membrane used as the petroleum oil absorbing material in this example. The various test results and performance parameters of the three-layer polypropylene microporous membrane used as petro...

Embodiment 3

[0062] In this example, a three-layer co-extruded composite microporous membrane of polypropylene / polyethylene / polypropylene with a thickness of 12 μm, a porosity of 60%, and an average pore diameter of 36 nm was prepared by the melt stretching method as a petroleum oil-absorbing material.

[0063] Among them, the polypropylene / polyethylene / polypropylene three-layer co-extruded composite microporous membrane is prepared by Shenzhen Zhongxing New Material Technology Co., Ltd. according to the battery separator production process. After testing, the air permeability of the polypropylene / polyethylene / polypropylene three-layer composite microporous membrane in this example is 30s / 100mL, and the water contact angle is 100.4°. Test method is the same as embodiment 1.

[0064] The polypropylene / polyethylene / polypropylene three-layer co-extruded composite microporous membrane used as petroleum oil-absorbing material in this example was tested in the manner of Example 1 for tensile str...

Abstract

The invention discloses a petroleum oil absorption material and application thereof. The petroleum oil absorption material is a polyolefin microporous membrane prepared through a melt stretching method or a phase separation method, the air permeability value of the polyolefin microporous membrane is 30-500s / 100mL, the water contact angle is 80-120 degrees, and the oil absorption amount is larger than 9.3g / m<2>. According to the petroleum oil absorption material, the polyolefin microporous membrane adopting special process and parameters has efficient oil absorption rate and hydrophobicity, notonly is high in oil absorption amount and high in oil absorption speed, but also is good in retention effect after oil absorption, and can be applied to all fields needing oil absorption materials. The petroleum oil absorption material provided by the invention can effectively recover petroleum, is simple and convenient to use, can be recycled in itself, and is low in cost and safe to operate.

Description

technical field [0001] The application relates to the field of oil-absorbing materials, in particular to a petroleum oil-absorbing material and its application. Background technique [0002] In recent years, with the rapid development of the economy and the improvement of people's living standards, the depletion of non-renewable energy and the aggravation of environmental pollution have followed. People pay more and more attention to the sustainable development of ecological environment and environment-friendly society. Petroleum is known as the "blood of industry" and is an important resource and strategic reserve material. Oil spill pollution incidents may occur during the storage, transportation, and use of oil. According to statistics, the oil and petroleum products leaked into the ocean through various channels account for about 0.5% of the world's total oil, and the amount of oil poured into the ocean is as high as 2 million to 10 million tons. The oil discharged int...
