Description
Technical Field
The invention relates to a preparation method and application of polyurethane hydrogel surface modified polyester fabric, and the preparation method and application of the polyurethane hydrogel surface modified polyester fabric are applied to the field of separation treatment of oil-water mixtures and oil-water emulsions.
Background
With the increase of industrial development and environmental protection demands, oil-water separation technology is becoming more and more important in various fields, such as offshore oil leakage treatment, chemical wastewater treatment, and the like. Polyester (PET) fabrics are widely used in filtration and separation fields due to their good mechanical properties, abrasion resistance and economy. However, insufficient hydrophilicity of PET fabrics limits their performance in oil-water separation applications. To solve this problem, the present study aimed at modifying PET fabric by surface coating to improve its hydrophilicity and oil-water separation effect. However, due to the weak adhesion on PET, the coating is easily detached from the substrate, resulting in a loss of surface functional properties. Therefore, it is necessary to improve the adhesive strength between the coating and the substrate.
Cation-pi interactions are interactions between positively charged cations and negatively charged electron clouds in pi systems. Recently, this interaction, which is as strong as hydrogen bonding, has attracted extensive attention from the scientific community. It has been applied in a number of research fields, such as chemical, materials science, biology and synthesis. In particular, cation-pi interactions are used for underwater adhesive materials. This interaction can effectively improve the bond strength between the phenyl substrate and the cationic group-bearing coating.
In addition, polyurethane is widely applied to the preparation of surface modified coatings by virtue of good mechanical properties, chemical resistance and film forming properties. In addition, due to the adjustability of the polyurethane component, the aim of directional modification of the surface of the substrate can be achieved by introducing different groups into the polyurethane chain segment.
The invention discloses a preparation method and application of polyurethane hydrogel surface modified polyester fabric. The polyurethane hydrogel coating prepared by the method forms a double-crosslinked network through physical crosslinking of cation-pi interaction and chemical crosslinking between carboxyl and aziridine groups to form a gel system with excellent mechanical properties. The hydrogel surface modified polyester fabric has the advantages of friction resistance, acid and alkali resistance, oil stain resistance, high separation efficiency and the like, and the prepared polyurethane hydrogel-polyester fabric composite film has high separation efficiency on oil-in-water emulsion prepared by different types of surfactants.
