Abstract

The invention discloses a preparation method for a water-repellent oil-repellent superhydrophobic fabric surface. The preparation method comprises the following steps: (1) weighing a cotton fabric, and preparing a cotton-cellulose macromolecular initiating agent under the action of the initiating agent and a catalyst; (2) grafting monomeric GMA on the prepared cotton-cellulose macromolecular initiating agent, vacuumizing a reaction system and introducing nitrogen, so as to obtain cotton cellulose grafted by the GMA, soaking the cotton cellulose grafted by the GMA in an acid solution, and hydrolyzing epoxy groups to form a cellulose surface rich in hydroxyl groups; and (3) performing acylation reaction between the cotton cellulose grafted by the GMA on the cellulose surface rich in hydroxyl groups and a monomer with low surface energy to obtain the water-repellent oil-repellent superhydrophobic surface. The preparation method is mild in reaction condition, simple, and easy to operate, can be realized at room temperature, and can guarantee the good superhydrophobicity and oil resistance without influencing of the comfort and the mechanical property of the cotton fabric.

Description

technical field

[0001] The invention relates to a preparation method for constructing a water-repellent and oil-repellent super-repellent surface on a fiber base, in particular to a preparation method for a water-repellent and oil-repellent super-repellent fabric surface. Background technique

[0002] With the in-depth study of "lotus leaves" and "rose petals" in nature, super-hydrophobic surfaces have attracted widespread attention. The formation of super-hydrophobic surfaces is mainly controlled by two factors, one is surface roughness, and the construction of surface The essence of roughness is to build a secondary micro-nano structure; the second is the modification of low surface energy. At present, the most important thing is to use fluorine-containing and long silicon-carbon chain compounds. Generally speaking, the longer the fluorocarbon chain, the lower its surface energy, which is more conducive to the construction of fabrics with excellent water and oil repellency...
