The invention relates to a wiredrawing screen cloth technology, and particularly relates to a preparation method of a wear-resistant flat-woven type wiredrawing screen cloth composite material. The preparation method comprises the following steps: step 1, preparing an outer layer embryonic membrane and an inner layer embryonic membrane; melt-bonding the outer layer embryonic membrane with the inner layer embryonic membrane to obtain a PVC embryonic membrane; step 2, respectively coating two sides of the flat-woven type wiredrawing screen cloth with a first layer of paste, and then coating thetwo sides with a second layer of paste; heating and plasticizing the wiredrawing screen cloth coated with the paste at 130-140 DEG C for 2-3 minutes; step 3, laminating the upper layer and the lower layer, which are nearly molten, of the PVC embryonic membrane with the wiredrawing screen cloth together to obtain the flat-woven type wiredrawing screen cloth composite material. The preparation method has the beneficial effects that the two sides of the wiredrawing screen cloth are respectively coated with the paste, and then the wiredrawing screen cloth is laminated with the PVC embryonic membrane, so that the problem of air tightness such as air leakage is solved; the outer layer of the PVC embryonic membrane is modified to be the membrane which is resistant to UV, weather-resistant, good in wear resistance and good in elasticity, and the inner layer of the membrane is easy to bond with the wiredrawing screen cloth coated with the paste.
