Embodiment 1

[0026] With non-woven fabric as the carrier, DVB and VTES as the hydrophobic modifier, through the solvothermal method. Take 1.5mL DVB and 0.5mL VTES into a 50mL autoclave, add 33ml of ethyl acetate, and 2% of the total monomer mass catalyst AIBN, after fully dissolved, put them in a 100°C oven for solvothermal for 10h ; After natural cooling, take out the modified non-woven fabric, clean it with absolute ethanol, and then place it in a 0.1mol L -1 Stand still in the ethanol solution of ammonia water at 25°C for 60min, and finally dry in an oven at 50°C.

Abstract

The invention provides a preparation method of a superhydrophobic non-woven fabric material prepared from P(DVB (Divinyl Benzene)-VTES(Vinyl Triethoxysilane)). The preparation method is characterized by comprising the following steps: step one, carrying out solvothermal reaction on a mixed solution which is impregnated with a non-woven fabric and contains DVB and VTES in the presence of a catalyst; step two, soaking a product obtained in the step one with an alkaline solution to obtain the superhydrophobic non-woven fabric material prepared from the P(DVB-VTES). According to the preparation method of the superhydrophobic non-woven material prepared from the P(DVB-VTES), provided by the invention, the non-woven fabric is used as a carrier; most non-woven fabrics are used as packaging materials and have extremely-low recycling rate; according to the preparation method provided by the invention, the waste of resources is greatly reduced.

Description

technical field [0001] The invention relates to a preparation method of a P(DVB-VTES) superhydrophobic non-woven fabric material and its application, belonging to the technical field of environmental functional material preparation. Background technique [0002] With the development of the application of oil in industry, oil pollution incidents occur frequently, especially in water environment. Because oil is difficult to be biodegraded and removed in water, it has strong bioaccumulation after entering the environment, which poses a potential threat to humans and marine organisms. Therefore, efficient and rapid removal of oil pollutants in water is of great importance. important meaning. At present, the commonly used methods for removing oil pollutants in water mainly include adsorption treatment, chemical method for dispersion and sedimentation treatment, microbial degradation and on-site combustion, etc. However, these methods have their own limitations, such as long trea...
