Problems solved by technology

Metal-based fillers have good electrical conductivity, but their high density is prone to sedimentation, and their application is limited due to their high price.
Although carbon-based fillers are widely used due to their good electrical conductivity, corrosion resistance and low cost, they cannot be selected in some fields due to reasons such as dark color, difficulty in cleaning, and easy cracking.
The conductive zinc oxide in the metal oxide filler has been widely used because of its certain conductivity and the ability to prepare light-colored conductive coatings. For example, CN101580625A discloses a method for preparing a light-colored static-conductive filler, but the con

Abstract

The invention relates to a non-woven fabric, and a preparation method and application thereof. The preparation method comprises the following steps of using oxidized graphene as ultraviolet absorption packing; uniformly mixing the oxidized graphene and zinc oxide nano coating in water; coating two sides of a non-woven fabric by using the mixture; and drying and molding to obtain the non-woven fabric. Average transmittance of the non-woven fabric in a long-wave ultraviolet region is lower than 3%; the decrease amplitude of the transmittance of the non-woven fabric in a visible light region is smaller than the decrease amplitude of the transmittance of a pure non-woven fabric in the visible light region by 30%-50%; the non-woven fabric is good in anti-ultraviolet property, and is washable; properties of the non-woven fabric can still be maintained even if the non-woven fabric is violently stirred in water for 30 days; and moreover, the non-woven fabric has characteristics of good conductivity, anti-static property, light color and environmental protection, and can be used in fields of ultraviolet protective clothing, anti-ultraviolet screen windows, anti-ultraviolet tarpaulin and anti-static clothes.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a non-woven fabric, its preparation method and its application. Background technique [0002] Non-woven fabric is a widely used material in daily life. It has the characteristics of moisture-proof, breathable, flexible, light weight, non-toxic, non-irritating, low price, and recyclable. However, due to its large number of voids, It makes light easy to pass through, and its UV protection performance is poor. Generally speaking, the anti-ultraviolet performance of non-woven fabrics can be improved by adding anti-ultraviolet additives to the non-woven fabric or coating its surface. Commonly used anti-ultraviolet additives include silicon dioxide, zinc oxide, aluminum oxide, etc. Although these inorganic materials have anti-ultraviolet properties, they need to be added in a relatively high amount to achieve the ideal anti-ultraviolet effect, which will seriousl...
