Abstract

The invention discloses a preparation method of a super-amphiphobic infrared stealth fabric, which is characterized by comprising the following steps: (1) preparing a dopamine aqueous solution, adjusting the pH value to 7.5-9, then immersing the fabric into the dopamine aqueous solution for 8-24 hours, and then cleaning and airing; (2) preparing a functional coating solution: adding hydrotalcite, hollow silicon dioxide, polyurethane, nano metal or nano metal oxide and perfluorinated organosilane into an organic solvent for dispersion; and (3) immersing the fabric cleaned and aired in the step (1) into the functional coating solution prepared in the step (2), and heating at 50-100 DEG C for 5-30 minutes to obtain the required super-amphiphobic infrared stealth fabric. The invention further discloses the super-amphiphobic infrared stealth fabric prepared by adopting the preparation method. Compared with the prior art, the super-amphiphobic infrared stealth fabric has the super-amphiphobic property and the infrared stealth property at the same time.

Description

technical field [0001] The invention relates to the technical field of fabric surface modification, in particular to a super-amphiphobic infrared stealth fabric and a preparation method thereof. Background technique [0002] Traditional fabrics are generally neither oil-proof nor waterproof, and are easily polluted by water-soluble stains such as juice, tea soup, etc. and by oily stains such as vegetable oil, diesel oil, etc. Therefore, it is very necessary to perform super-amphiphobic (super-hydrophobic and super-oleophobic) treatment on fabrics, especially military clothing needs to be often used in harsh environments in the wild. For example, the patent application No. 202110159053.8 (publication No. CN112813683A) of the invention patent "A kind of super-amphiphobic fabric and its preparation method" directly constructs a rough structure on the surface of the fabric through a one-step reaction, and reduces the surface energy of the fabric to form a super-amphiphobic surfa...
