Problems solved by technology

[0002] The brushed mesh composite material in the prior art is produced by a coating process. The double-sided brushed mesh is coated on both sides by a vertical oven. If the amount of paste is not enough, it is necessary to add multiple coats of paste, and the gap between the materials in the coating is relatively large, so it is prone to inflation and air leakage, that is, poor air tightness; in addition, the coating process formula can only use paste resin materials, paste resin It is mixed with plasticizer and stabilizer to make a paste slurry and used in the coating process. After plasticization, there will be many small pores on the coating surface. The existence of these small pores will cause the product to leak easily.

Abstract

The invention relates to a wire-drawing screen cloth technology, in particular to a wire-drawing screen cloth composite material and a preparation method thereof. The preparation method comprises the following steps: 1, preparing an outer-layer gray film and an inner-layer gray film, wherein the outer-layer gray film and the inner-layer gray film are melted and laminated to obtain PVC gray films; 2, respectively coating two side surfaces of plain weave type wire-drawing screen cloth with first layers of paste and then with second layers of paste, and heating and plasticizing the pasted wire-drawing screen cloth at 130 to 140 DEG C for 2 to 3 minutes; 3, laminating the upper and lower layers of PVC gray films at a nearly melted state with the wire-drawing screen cloth, so as to obtain the plain weave type wire-drawing screen cloth composite material. The plain weave type wire-drawing screen cloth composite material has the beneficial effects that the two side surfaces of the wire-drawing screen cloth are respectively coated with the paste agents, and then the wire-drawing screen cloth is laminated with the PVC gray films, so that the problem of air leakage is solved; the outer layers of the PVC gray films are modified into anti-UV layers, so that the plain weave type wire-drawing screen cloth composite material is high in weather resistance and wear resistance and high in elasticity; the inner layers of the PVC gray films can be firmly adhered with the pasted wire-drawing screen cloth.

Description

technical field [0001] The invention relates to the technical field of textile materials, and its characteristics relate to a preparation method of a flat-woven wire drawing mesh composite material. Background technique [0002] The brushed mesh composite material in the prior art is produced by a coating process. The double-sided brushed mesh is coated on both sides by a vertical oven. If the amount of paste is not enough, it is necessary to add multiple coats of paste, and the gap between the materials in the coating is relatively large, so it is prone to inflation and air leakage, that is, poor air tightness; in addition, the coating process formula can only use paste resin materials, paste resin It is mixed with plasticizer and stabilizer to form a paste slurry and used in the coating process.
