Anti-ultraviolet umbrella fabric

Abstract

The invention discloses an anti-ultraviolet umbrella fabric, which comprises a cloth layer, a coating layer, a thin film layer and a pressure adhesive layer. The specific formula of each layer of thefabric is as follows: the cloth layer is prepared from the following components by mass percent: 50 to 75% of polymethyl acrylate fiber, 20 to 40% of cuprammonium fiber and 20 to 35% of polyimide fiber; the coating layer is prepared from the following components by mass percent: 40 to 60% of phytic acid, 15 to 25% of defoamer, 10 to 15% of ammonium phosphate and 10 to 15% of zinc yellow; the thinfilm layer is prepared from the following components by mass percent: 40 to 60% of PVDF, 30 to 40% of acrylic resin, and 20 to 35% of chlorinated PVC resin; the pressure adhesive layer is prepared from the following components by mass percent: 45 to 85% of natural rubber, 8 to 16% of anti-ozone anti-aging agent and 20 to 30% of hard pottery clay. The anti-ultraviolet umbrella fabric provided by the invention has the advantages that the waterproof effect can be well improved by providing a four-layer structure, and the thin film layer arranged on the coating layer can prevent a coating from wearing severely after long-term use.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to an anti-ultraviolet umbrella fabric. Background technique [0002] UV-resistant fabric is a material that protects the human body from excessive ultraviolet radiation. Commonly used fabrics are polyester spinning, pongee, and five pieces of satin. Using this fabric can prevent human skin from sunburn and aging. Preventing ultraviolet rays from harming the human body has been valued by more and more consumers. Ultraviolet rays in the solar spectrum not only make textiles fade and embrittle, but also cause sunburn and aging of human skin, resulting in melanin and stains, and more seriously, it can induce cancer and endanger human health. The impact of ultraviolet rays on the human skin and eyes is the most obvious. The skin's absorption of UV rays is related to its wavelength. The shorter the wavelength, the smaller the depth of penetration into the skin, and the weaker the melanin afte...
