Abstract

The present invention relates to an ultra-high-flux nano-fiber waterproof gas-permeable membrane and a preparation method thereof, and belongs to the field of textile technology material synthesis. The ultra-high-flux nano-fiber waterproof gas-permeable membrane is prepared from the following two components such as bifunctional group-modified nano-silica particles and a polymer nano-fiber membrane, wherein the nano-fiber membrane uses the bifunctional group-modified nano-silica particles as the adhesive between fibers, such that the rub resistance of the membrane material can be enhanced, the nano-fiber surface roughness can be increased, and the water resistance of the fiber membrane can be increased. According to the present invention, the prepared ultra-high-flux nano-fiber waterproof gas-permeable membrane has characteristics of small pore size, high porosity and enhanced adhesion structure, can provide advantages of high water resistance, high moisture permeable flux and high strength in the waterproof and moisture permeation field, has the moisture permeation flux of more than or equal to 18000 g / m<2> / d, has the water resistance of more than or equal to 100 kPa, and has wide practical application prospects.

Description

technical field

[0001] The invention relates to a waterproof and breathable membrane, in particular to an ultra-high flux nanofiber waterproof and breathable membrane and a preparation method thereof. Background technique

[0002] Waterproof & Moisture Permeable Fabric (Waterproof & Moisture Permeable Fabric) is usually also called waterproof and breathable fabric, and it is generally called breathable fabric (Waterproof but Breathable Fabric) in foreign countries. It is a fabric that can prevent rain, perspire and breathe. It appears when human beings constantly improve self-protection against the encroachment of nature. During the wearing process, water cannot penetrate the fabric under a certain pressure, but the sweat emitted by the human body can be transmitted to the outside world through the fabric in the form of water vapor, without condensation and accumulation between the human body surface and the fabric, keeping the wearer dry and warm. Therefore, it is called "...
