Problems solved by technology

[0005] At present, superhydrophobic fiber cloth is widely used in self-cleaning and other fields, but relatively few are used in the field of oil-water separation, and the preparation method is relatively complicated. Most of them are modified fiber cloth itself, and the oil-water separation effect is relatively low, and can be Not very repeatable

Embodiment 1

[0035] In the first step, MMA, HPA, 2-EHA, and GMA are used as monomers, AIBN is used as an initiator, and butyl acetate is used as a solvent to synthesize an acrylic resin. The percentages in this step are the percentages of the total mass of the raw materials used to synthesize the acrylic resin. First add 27% butyl acetate into a three-necked flask and heat to 82°C, then accurately weigh 1.8% AIBN, 0.5% chain transfer agent, 23.68% MMA, 3.125% HPA, 23.195% 2-EHA, 12.5% ​​GMA and 3.5% Butyl acetate, mixed and dissolved, was added dropwise into a three-necked flask, and the dropping time was controlled to be 4 hours. After the dropwise addition was complete, the temperature was raised to 85°C, kept for 5 hours, and then 0.2%g AIBN and 4.5%g butyl acetate were added Ester, continue to keep warm for 1 hour, cool down to 60 ℃ and discharge, and the acrylic resin containing epoxy with a solid content of 65% can be obtained; the glass transition temperature of the above-mentioned r...

Embodiment 2

[0040] What is different from Embodiment 1 is:

[0041] In the first step, add 27% butyl acetate into a three-necked flask and heat it to 82°C, then accurately weigh 1.8% AIBN, 0.5% chain transfer agent, 26.745% MMA, 3.125% HPA, 20.13% 2-EHA, 12.5% GMA and 3.5% butyl acetate were mixed and dissolved, then added dropwise into a three-necked flask, and the dropping time was controlled to be 4 hours. After the dropwise addition was complete, the temperature was raised to 85°C and kept for 5 hours, and then 0.2% g AIBN and 4.5 %g butyl acetate, continue to keep warm for 1 hour, cool down to 60°C and discharge, and then the acrylic resin containing epoxy with a solid content of 65% can be obtained; the glass transition temperature of the above resin is about 10°C.

Embodiment 3

[0043] The difference from Example 1 is that

[0044] In the first step, add 27% butyl acetate into a three-necked flask and heat it to 82°C, then accurately weigh 1.8% AIBN, 0.5% chain transfer agent, 30.05% MMA, 3.125% HPA, 16.825% 2-EHA, 12.5% GMA and 3.5% butyl acetate were mixed and dissolved, then added dropwise into a three-necked flask, and the dropping time was controlled to be 4 hours. After the dropwise addition was complete, the temperature was raised to 85°C and kept for 5 hours, and then 0.2% g AIBN and 4.5 %g butyl acetate, continue to keep warm for 1 hour, cool down to 60°C and discharge, and then the acrylic resin containing epoxy with a solid content of 65% can be obtained; the glass transition temperature of the above resin is about 20°C.

Abstract

The invention discloses a method for preparing fluorescent superhydrophobic fiber cloth, which relates to the technical field of oil-water separation materials. Firstly, acrylic resin with epoxy groups is synthesized by solution polymerization; then the resin is obtained by fluorescent grafting and amino silicone oil modification. A fluorescent superhydrophobic resin is sprayed on the surface of a fiber cloth to obtain a fluorescent superhydrophobic fiber cloth. The beneficial effects of the present invention are: the preparation method is simple, only need to spray the synthetic resin on the surface of the fiber cloth to form a rough surface structure, and the amino silicone oil and acrylic resin in the fluorescent superhydrophobic resin will be in the curing process, and the acrylic resin component will be firm The strong adhesion on the surface of the fiber cloth provides strong adhesion, the amino silicone oil component makes the coating hydrophobic, and the fluorescence characteristics enable the naked eye to distinguish the coating effect of the fiber cloth. The prepared superhydrophobic fiber cloth is durable Friction, high temperature resistance, and long-term use separation efficiency remains above 99%.

Description

technical field [0001] The invention relates to the technical field of oil-water separation materials, in particular to a fluorescent superhydrophobic fiber cloth and a preparation method thereof. Background technique [0002] Since 1997, superhydrophobic surfaces have been studied for more than 20 years due to their unique properties and potential applications. However, so far, there have been no commercial practical applications other than the application of water-repellent agents to textile surfaces. Many researchers have focused on its surface modification to create other functions, including flame retardancy, UV protection, antibacterial action and self-cleaning ability. Among these modifications, superhydrophobic fiber cloth has attracted the most attention of researchers due to its wide application fields, such as jackets, protective clothing, tents, umbrellas, curtains, etc. [0003] Studies have shown that the micro-nano multi-level rough structure and low surface...
