The invention relates to a laminated
composite material synthesized of warp-knitted and
textile materials and PVC and discloses PVC laminated composite cloth comprising films formed through
extrusion method. The PVC laminated composite cloth comprises base cloth, a bottom film and a
surface film, wherein the bottom film and the
surface film are arranged at the two sides of the base cloth and are both PVC thin films The PVC laminated composite cloth has the advantages that the cost is low, the applicability is strong, the performances are good, specifically, the peeling strength, the elasticity, the tensile strength and the tearing strength are obviously improved and the waterproof performance, the
flame-retardant performance and the
ageing resistance are excellent. The invention also discloses a preparation method of the PVC laminated composite cloth comprising films formed through
extrusion method. The preparation method comprises the following steps of: firstly
compositing the specific bottom film prepared by
extrusion and the base cloth, then
compositing with the specific surface films prepared by extrusion. The preparation method disclosed by the invention has the advantages that since no boiler is used and
carbon dioxide is not exhausted,
air pollution is hardly caused; only cooling circulation water is used, so
water pollution cannot be caused; and the process is simple, the
energy consumption is low, the popularity rate is high, the cost is low, the profit margin is large and the application prospect is wide.
