Embodiment 1

[0092] The sponge matrix (nano sponge, 1 × 1 × 1cm 3 ) in deionized water and absolute ethanol in order to ultrasonically wash repeatedly several times, rinse with deionized water, and dry in an oven for later use.

[0093] (1) Disperse 1g of polyvinyl chloride SG-8 and 0.5g of hydrophobic fumed nano-silica in 100mL of tetrahydrofuran, place in a glass bottle with a cover and stir with a magnetic stirrer until uniformly dispersed, and add 1mg of 3-aminopropyl Triethoxysilane was stirred for 1 hour until it was uniformly dispersed to obtain an impregnating solution with a mass content of polyvinyl chloride of 10 mg / mL.

[0094] (2) The dried nano-sponge (1×1×1cm 3 ) soaked in the soaking solution of step (1) for 12h. The sponge was taken out, ventilated and dried at room temperature for 3 hours to volatilize the organic solvent, and then placed in an oven at 60°C for 6 hours to obtain the hydrophobic sponge material A1. Among them, the density of the hydrophobic sponge mater...

Embodiment 2

[0096] Prepare hydrophobic sponge material with reference to the method described in Example 1, the difference is that in step (1), add 0.5g polyvinyl chloride SG-8, 1g hydrophobic fumed nano-silica and add 0.5mg 3-aminopropyl triethyl Oxygensilane, obtains hydrophobic sponge material A2. Among them, the density of the hydrophobic sponge material A2 is 0.019g / cm 3 , the porosity is 96.99%.

Embodiment 3

[0098] Prepare the hydrophobic sponge material with reference to the method described in Example 1, the difference is that in step (1), add 1.5g polyvinyl chloride SG-8, 0.5g hydrophobic type fumed nano-silica and 1.5mg 3-aminopropyl triethyl Oxygensilane, obtains hydrophobic sponge material A3. Among them, the density of the hydrophobic sponge material A3 is 0.021g / cm 3 , the porosity is 96.93%.

Abstract

The invention relates to the field of removal of organic pollutants in water, in particular to a hydrophobic modifier composition and a hydrophobic sponge material as well as a preparation method and application thereof. The hydrophobic modifier composition comprises polyvinyl chloride, nano silicon dioxide and liquid siloxane; wherein the mass ratio of the polyvinyl chloride to the nano silicon dioxide to the liquid siloxane is (800-1200): (200-4800): 1. The hydrophobic sponge material obtained by using the hydrophobic modifier composition can quickly and effectively separate oil from water, can still keep higher adsorption capacity after being recycled for multiple times, and can be used for emergency treatment of oil leakage on water.

Description

technical field [0001] The invention relates to the field of removing organic pollutants in water, in particular to a hydrophobic modifier composition, a hydrophobic sponge material and a preparation method and application thereof. Background technique [0002] With the development of the petrochemical industry, the types and quantities of hazardous chemicals (hereinafter referred to as hazardous chemicals) used in the world have increased significantly. The import and export of these hazardous chemicals mostly depend on ship transportation, so the risk of water leakage accidents is relatively high. The physical behavior of benzene series hazardous chemicals leaked into water belongs to the floating volatile (FE) category, that is, the leaked benzene series can not only pollute the air in the form of steam, but also float on the water surface and cause water quality deterioration. In addition, benzene series have moderate to high toxicity to certain microalgae, fish, and cru...
