specific Embodiment approach 1

[0019] Specific embodiment one: the preparation method of the oil-water separation cloth of the present embodiment is carried out according to the following steps:

[0020] 1. Clean and dry the cloth;

[0021] 2. Add sodium hydroxide and zinc nitrate hexahydrate particles with a mass fraction of 1.3% and 1% of water, respectively, into water successively, stir magnetically at 75±5°C for 24 hours, wash with water, centrifuge, and dry;

[0022] 3. The zinc oxide particles obtained by this method are hydrophobically modified with stearic acid with a mass fraction of 8%, the modification time is 3 hours, the temperature is 75±5°C, washed with alcohol, and dried;

[0023] Four, configure the tetrahydrofuran solution of polystyrene, the consumption of polystyrene is 2.22% of tetrahydrofuran mass, the hydrophobic zinc oxide particle that mass fraction is 2.22% of tetrahydrofuran is uniformly dispersed wherein;

[0024] 5. Spread the cloth on a clean watch glass, absorb a certain amo...

specific Embodiment approach 2

[0026] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the mass fraction of polystyrene in step 4 is 4% of tetrahydrofuran. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0027] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the mass fraction of polystyrene in step four is 0.88% of tetrahydrofuran. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a preparation method of an oil-water separation fabric, belonging to the technical field of functional materials. The preparation method comprises the following steps of: 1, cleaning and drying the fabric; 2, sequentially adding sodium hydroxide and zinc nitrate hexahydrate particles into water, magnetically stirring, washing with water, centrifuging and drying; 3, carrying out hydrophobic modification on the zinc oxide particles obtained by the method by using stearic acid, washing with alcohol, and drying; 4, preparing a tetrahydrofuran solution of polystyrene, and uniformly dispersing the hydrophobic zinc oxide particles into the tetrahydrofuran solution; and 5, carrying out the method 1 comprising the steps of soaking the fabric into the mixture solution in the step 4, taking out and then placing in a clean watch glass and drying at room temperature, or carrying out the method 2 comprising the steps of spreading the fabric in the clean watch glass, sucking a certain of the mixture solution in the step 4 and uniformly coating on the surface of the fabric, and drying at room temperature to obtain the oil-water separation fabric. The preparation method disclosed by the invention has the advantages of simple process, low economic cost, short period, small energy consumption, no need of complex special devices and no existence of multiple subsequent problems, and has great application prospects in the future.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a preparation method of an oil-water separation cloth with a micro-nano hierarchical structure. Background technique [0002] The free water in the oil is the key factor affecting the quality of the oil. Therefore, the development of an economical, practical and recyclable oil-water separation material is an important topic in the filtration and separation industry. [0003] Chinese Patent Application No. 201110071481.1 discloses an oil-water separation device and a preparation method, which uses metal mesh to pass oil and retain water. Chinese Patent Application No. 200910242075.X discloses a method for preparing an anti-pollution oil-water separation ultrafiltration membrane. Although both have a certain oil-water separation effect, they are not stable enough, such as not resistant to acid, alkali, and salt, and use fluorine-containing compounds, which...
