Embodiment 1

[0018] Mix 15 mL of toluene, chloroplatinic acid-isopropanol solution (1 wt%), 295 μL, and ViD 4 46.78 g (136 mmol), stir evenly, then add PHMS 4.44g (68 mmol Si-H), continue stirring evenly, and obtain an immersion solution. Soak a clean sponge in the immersion liquid, after it is completely soaked, take out and squeeze out the excess immersion liquid, then place it in a drying oven, dry and solidify at 90~100°C to obtain a silicone modified sponge S 2:1 .

Embodiment 2

[0020] Mix 15 mL of toluene, chloroplatinic acid-isopropanol solution (1 wt%), 295 μL, and ViD 4 46.78 g (136 mmol), stir evenly, then add 2.22 g (34 mmol Si-H) of PHMS, continue stirring evenly, and obtain an immersion solution. Soak the clean sponge in the immersion liquid, after it is completely soaked, take out and squeeze out the excess immersion liquid, then place it in a drying oven, dry and solidify at 90~100°C, and obtain the silicone modified sponge S 4:1 .

Embodiment 3

[0022] Mix 15 mL of toluene, chloroplatinic acid-isopropanol solution (1 wt%), 295 μL, and ViD 4 46.78 g (136 mmol) of Si-H, stirred evenly, then added 8.88 g (136 mmol Si-H) of PHMS, and continued to stir evenly to obtain an immersion solution. Soak the clean sponge in the immersion liquid, after it is completely soaked, take out and squeeze out the excess immersion liquid, then place it in a drying oven, dry and solidify at 90~100°C, and obtain the silicone modified sponge S 1:1 .

Abstract

The invention discloses a method for preparing efficient oil-water separation sponge. Porous sponge sold on the market is adopted as a base body, an addition reaction of polymethylhydrosiloxane (PHMS) and tetravinyl tetramethylcyclotetrasiloxane (Vid4) is adopted, an organosiloxane coating is established on the surface of the sponge, that is, an organic silicone hydrophobic material is obtained, and thus the efficient oil-water separation sponge with a high superhydrophobicity characteristic and a super-oleophilicity characteristic is prepared. The method is simple in operation, raw materials are cheap and easy to obtain, the prepared efficient oil-water separation sponge can separate oil / water mixtures in a layered mode efficiently and automatically and can be recycled, and a new thought is provided for developing an intelligent oil-water separation material and relieving huge pressure of the ecological environment.

Description

technical field [0001] The invention belongs to the technical field of preparation of functional polymer materials, and in particular relates to a preparation method of a three-dimensional high-efficiency oil-water separation sponge. Background technique [0002] The reusable three-dimensional oil-water separation material is based on the superoleophilic-superhydrophobic surface / interface properties, which can efficiently and automatically separate layered oil / water mixtures, and even separate oil-water emulsions, including water-in-oil and Oil-in-water emulsion. The problem of oil-water separation has been associated with crude oil spills for a long time. Economic needs and wars are the main reasons for various oil spills. Some major oil spills have caused immeasurable damage to natural ecology and economy. Accidents cannot be completely avoided, so after an accident, efficient and timely emergency response is particularly important. Super-oleophilic and super-hydrophobic...
