Method for manufacturing thickened, reinforced, flame-retardant and durable polyethylene woven cloth and corresponding product

The invention provides a method for manufacturing a thickened, reinforced, flame-retardant and durable polyethylene woven cloth. The method comprises the following steps that 1, flame-retardant masterbatch is prepared; 2, anti-aging masterbatch is prepared; 3, flat filaments are produced, wherein single-layer filaments are adopted as warp filaments, weft filaments are folded and drawn into folded filaments after being split, and the single folded filament has 2-5 layers; 4, a cloth base is woven, a filament spindle performs weaving in a flat weaving machine or circular weaving machine to make the woven cloth base material, and every two warp filaments are folded into a group for weaving; 5, compositing is performed, LDPE and high-melting-index LLDPE are taken as main raw materials, 8%-25% by mass of the flame-retardant masterbatch, 3%-10% by mass of the anti-aging masterbatch and 1%-5% by mass of titanium dioxide masterbatch are added, the materials are extruded into a melt film by a single-screw extruder, and the melt film is arranged on the woven cloth base material in a tape casting mode. The invention further provides the polyethylene woven cloth manufactured through the method.
