Embodiment 1

[0018] The anti-ultraviolet umbrella fabric of this embodiment uses the cloth layer as the base layer, and is provided with a paint layer on one side of the cloth layer to increase the look and feel, and is covered with a paint layer to keep the paint layer attached to the cloth layer for long-term use. The upper film layer; on the other side of the cloth layer, there is an adhesive layer bonded to the surface of the cloth layer by bronzing process, wherein the specific formula of each layer of material is as follows: cloth layer: including polymethyl acrylate fiber in mass fraction 50-75%, cupro ammonia fiber 20-40% and polyimide fiber 20-35%; coating layer: including cyclohexyl hexaphosphate ester 40-60% in mass fraction, defoamer 15-25% %, ammonium phosphate 10-15% and zinc yellow 10-20%; film layer: including PVDF40-60% in mass fraction, acrylic resin 30-40% and perchlorethylene resin 20-35%; adhesive layer: Including 45-85% of natural rubber, 8-16% of anti-ozone anti-agin...

Embodiment 2

[0026] The present embodiment is further defined on the basis of the above-mentioned embodiment 1, including polymethyl acrylate fiber 60%, cupro ammonia fiber 20% and polyimide fiber 20% in mass fraction; coating layer: comprising Cyclohexyl hexaphosphate ester 55% by mass fraction, defoamer 15%, amine phosphate 15% and zinc yellow 15%; film layer: including PVDF50% by mass fraction, acrylic resin 30% and perchlorethylene 20% resin; adhesive layer: including 70% natural rubber, 9% anti-ozone anti-aging agent and 21% hard clay in mass fraction. Other parts of this embodiment are the same as those of the foregoing embodiment, and will not be repeated here.

Embodiment 3

[0028] The present embodiment is further defined on the basis of the above-mentioned embodiment 1, which includes 50% of polymethylacrylate fiber, 25% of cupro ammonia fiber and 25% of polyimide fiber in terms of mass fraction; coating layer: Including 40% cyclohexyl hexaphosphate ester in mass fraction, 25% defoamer, 15% amine phosphate and 20% zinc yellow; film layer: including PVDF45% in mass fraction, 35% acrylic resin and overcoat 20% vinyl chloride resin; adhesive layer: including 58% natural rubber, 12% anti-ozone anti-aging agent and 30% hard clay in terms of mass fraction. Other parts of this embodiment are the same as those of the foregoing embodiment, and will not be repeated here.

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...
