Problems solved by technology

[0004] At present, during the use of the film used for gas separation, the surfactant on the film is easily carried away by the air flow, which causes the loss of the surfactant on the film and affects the service life of the film.

Embodiment

[0042] see Figure 1-4 , a preparation method of surfactant composite adhesive film, and its technological process is:

[0043] S1, firstly prepare a single-layer adhesive film. After stirring and mixing the raw materials of the film-forming liquid at 40°C for 6 hours, the rotating speed of the stirring device is 300 rad / min to obtain a uniform and transparent film-making liquid. The raw materials of the film-forming liquid are: 5 parts poly(ethylene-vinyl acetate), 5 parts polymethyl methacrylate, 10 parts Triton X-114 and 80 parts tetrahydrofuran;

[0044]S2, the film-forming liquid is scraped on a glass plate with a stainless steel scraper to obtain a liquid film, the scraping temperature is 40°C, and the liquid film is air-dried at room temperature for 24 hours to obtain a surfactant gas separation film, a gas separation film The thickness of the film is 100-300 μm, and the surfactant gas separation film can be screened for different gases. Hereinafter, the film refers to...

Abstract

The invention discloses a method for preparing a surfactant composite adhesive film, which belongs to the field of surfactants. After laying two surfactant gas separation adhesive films on two panels, the panels are installed in a film compounding device. Pressurize one panel to make the two panels gradually approach, and at the same time, the laminating device sprays surfactant particles between the two panels; when the two panels are combined, heat the adhesive film on the panel to restore the adhesiveness of the adhesive film , to capture the surfactant particles, so that a surfactant powder layer is formed in the middle of the formed composite film; finally, the composite film is cooled and dried to obtain a composite film containing a compressed surfactant dust layer. During the layering process, the adhesive film is used for preliminary interception and filtration to prevent the surfactant from adsorbing substances in the gas. At the same time, the viscosity of the adhesive film binds the surfactant to prevent the surfactant from being carried away by the airflow passing through the film layer.

Description

technical field [0001] The invention relates to the field of surfactants, in particular to a preparation method of a surfactant composite adhesive film. Background technique [0002] Surfactant refers to a substance that can significantly reduce the surface tension of the target solution. It has a fixed hydrophilic and lipophilic group, and can be aligned on the surface of the solution. The molecular structure of surfactants is amphoteric: one end is a hydrophilic group, the other end is a hydrophobic group; the hydrophilic group is often a polar group, such as carboxylic acid, sulfonic acid, sulfuric acid, amino or amine group and its salts , hydroxyl, amide group, ether bond, etc. can also be used as polar hydrophilic groups; while hydrophobic groups are often non-polar hydrocarbon chains, such as hydrocarbon chains with more than 8 carbon atoms. Surfactants are divided into ionic surfactants (including cationic surfactants and anionic surfactants), nonionic surfactants,...
