A kind of anti-ultraviolet pvc coating fabric and its coating device

Abstract

The invention provides an anti-ultraviolet PVC coating layer fabric, belonging to the technical field of fabrics. According to the anti-ultraviolet PVC coating layer fabric, the problem of poor ultraviolet resistance in the prior art is solved. The anti-ultraviolet PVC coating layer fabric comprises base cloth, wherein a flame-retardant layer, a waterproof layer, an anti-ultraviolet layer and an anti-slide layer are sequentially arranged on the front surface of the base cloth, a plurality of connecting grooves are uniformly formed in the upper end of the flame-retardant layer, and connecting strips matched with the connecting grooves are uniformly arranged at the lower end of the waterproof layer and are located in the connecting grooves. A coating device of the anti-ultraviolet PVC coating layer fabric comprises a stander, wherein a coating tank is fixedly arranged on the stander, an inlet is formed in one side of the coating tank, and an outlet is formed in the other side of the coating tank; and a spraying device capable of spraying coatings to a cloth material is arranged in a cavity I and comprises a body with a trapezoidal cross section, a cavity II is formed in the body, a plurality of discharging holes are uniformly formed in the lower end of the body, and one-way valves are arranged in the discharging holes. The anti-ultraviolet PVC coating layer fabric has the advantage of good ultraviolet resistance.

Description

technical field [0001] The invention belongs to the technical field of fabrics, and relates to a fabric, in particular to an anti-ultraviolet PVC coated fabric and a coating device thereof. Background technique [0002] With the development of the modern industrial revolution, the ozone layer in the atmosphere is constantly being destroyed. The ozone layer is the best protective umbrella for the earth, it can absorb most of the ultraviolet rays from the sun. However, nearly two decades of scientific research and atmospheric observations have found that the ozone layer has been thinning, and an ozone hole has even been formed over the Antarctic. Generally, ultraviolet rays can be divided into short wave (UVC: 200~290nm), medium wave (UVB: 290~320nm) and long wave (UVA: 320~400nm). The results of the study show that moderate exposure to ultraviolet rays is beneficial to human health, but excessive exposure to ultraviolet rays can cause some damage. Among them, when UVC pass...
