Green self-cleaning super-hydrophobic oleophobic coated fabric

Abstract

The invention discloses a green self-cleaning super-hydrophobic oleophobic coated fabric. The fabric comprises a piece of base cloth. One side of the base cloth is formed by a plurality of uniformly arranged same-shaped rectangular prominences with certain spaces. The other side of the base cloth has a planar structure. A coat which expands on contacting liquid is coated on the whole surface of the base cloth side with the rectangular prominences. The fabric provided by the invention is advantaged in reasonable structure and good hydrophobic and oleophobic performance. The fabric has a self-adaptive function against water and oil stains.

Description

technical field [0001] The invention relates to a hydrophobic and oil-repellent coated fabric. Background technique [0002] Hydrophobic oil-repellent coated fabric is a kind of fabric that can alienate and repel various water liquid media and oil stains within a certain period of time after special finishing. Because it can adapt to the requirements of modern society for the high functionalization of textiles, It has been widely used in fields such as industry, military, disaster relief, daily life, medical care, special protection and field operations, and has a good market prospect. [0003] However, in the production and processing of traditional hydrophobic and oil-repellent coated fabrics, most of them use the principle of forming a dense sealing layer on the surface of the base fabric and increasing the contact angle of the coating to realize the hydrophobic and oil-repellent functions of the fabric. Although the method can achieve better results, the air and moistur...

Problems solved by technology

[0009] Zhejiang University proposed a TiO in patent document 200710071365.3 2 The preparation method of the pillared bentonite adsorption-photocatalysis integrated catalyst can be seen from its description, the invention is mainly used in the purification treatment of waste water, air and gas pollution, etc., and it is not mentioned that it can be used for self-adaptive adjustment of water and oil. Green Self-cleaning superhydrophobic and oil-repellent coated fabrics

[0010] In addition, Wujiang Hengrun Weaving Factory and Wujiang Beishe Shengyuan Textile Auxiliary Factory proposed a method for preparing a waterproof and moisture-permeable coated fabric and a modified polyurethane waterproof and moisture-permeable coating in patent documents 201010251527.3 and 201110245996.9 respectively. The preparation method of layer fabric, it can be seen from its description that the waterproof and moisture-permeable coating fabric produced by it does not have the self-adaptive adjustment function to water and oil stains, and there is no mention of combining the structure of the base fabric with the coating agent, waterproofing agent and The combination of oil-repellent agents and the like makes a high-performance green self-cleaning super-hydrophobic oil-repellent coating fabric, and most of the patent documents about bentonite do not involve the fabric field
