Embodiment 1

[0021] Dissolve 0.05 g of tridecafluorooctyltriethoxysilane in 50 mL of absolute ethanol, and stir magnetically at room temperature for 1 h; immerse 1 g of horn gourd fibers in the above solution for 3 s, and then ultrasonically clean them with absolute ethanol for about 1 min after separation. Vacuum drying at 60 °C, followed by heat treatment at 100 °C for 60 min, to obtain the oil-absorbing material of croissant melon fibers. The absorption rate of soybean oil by croissant melon fiber is 87 times (the absorption rate of soybean oil by non-silane-treated croissant melon fiber is 57 times).

Embodiment 2

[0023] Dissolve 2g of octadecyltrichlorosilane in 50 mL of toluene; immerse 2g of croissant melon fiber in the above solution for 1h, after separation, clean it ultrasonically with absolute ethanol for 20min, dry it in vacuum at 30°C, and then put it at 120°C After heat treatment for 120 min, the oil-absorbing material of croissant melon fiber was obtained. The absorption ratio of the oil-absorbing material to soybean oil is 73 times.

Embodiment 3

[0025] Dissolve 3 g of γ-methacryloxypropyltrimethoxysilane in 50 mL of methanol, and stir magnetically at room temperature for 8 h; immerse 5 g of melon fiber in the above solution for 20 min, and clean it ultrasonically with absolute ethanol for 30 min after separation , dried in vacuum at 40 °C, and then heat-treated at 150 °C for 90 min to obtain the oil-absorbing material of croissant melon fiber. The absorption ratio of the oil-absorbing material to soybean oil is 65 times.

Abstract

The invention discloses a silane-modified croissant fiber oil-absorbing material, which is obtained by soaking croissant fiber in a silane modifier solution, separating, cleaning, vacuum drying, and heat-treating at 100-200 DEG C. The oil-absorbing material has 65-90 times the absorption capacity of soybean oil and engine oil; the oil-absorbing equilibrium time is about 10 minutes, it has fast and efficient oil-absorbing capacity, and can quickly prevent oil from spreading. In addition, the present invention has cheap and easy-to-obtain raw materials, low product cost, simple preparation process, and biodegradable performance.

Description

technical field [0001] The invention relates to a natural oil-absorbing material, in particular to a silane-modified oil-absorbing material of horn gourd fiber. Background technique [0002] The ocean is a strategic base for human survival and sustainable development. When the coastal countries around the world are under the pressure of population expansion, resource shortage, and environmental degradation, they pay attention to, develop and utilize the ocean from a new perspective, and the ocean pollution problem that accompanies global industrialization has increasingly become the focus of attention. The frequent occurrence of marine oil spill accidents around the world has caused huge damage to the marine ecological environment and marine life, and brought immeasurable ecological disasters and economic losses. For example, the crude oil spill in the Gulf of Mexico in 2010 caused the most serious oil spill in the history of the United States; the oil spill in the Bohai Ba...
