[0022] The beneficial effects of the preparation method of the wire drawing mesh composite material of the present invention are:

[0023] (1) The viscosity of the coating agent is increased from 2000cps in the prior art to 10000-12000cps, so as to prevent the coating agent from penetrating into the middle wire-drawn mesh, thereby solving the bonding problem of the middle wire-drawn mesh;

[0024] (2) Firstly coat the two sides of the wire-drawn mesh with coating agent respectively, and then attach it to the PVC film. The plasticized coating agent also has small pores, which may cause air leakage, but add a layer After the PVC film, because there is no small air hole in the middle of the calendered PVC film, the small air hole of the plasticized coating agent can be blocked, so it can solve the problem of air leakage and air tightness, and has the technical effect of effectively improving the air tightness.

Abstract

The invention relates to a wire-drawing screen cloth composite material which comprises a PVC layer, a wire-drawing screen cloth layer, a first coating and a second coating. The first coating and the second coating are arranged on the two side faces of the wire-drawing screen cloth layer respectively so as to form a pre-compositing layer. The two side faces of the pre-compositing layer are attached to the PVC layer respectively to form the wire-drawing screen cloth composite material. The first coating and the second coating are each prepared from, by weight, 60-80 parts of diisononyl phthalate or dioctyl phthalate, 95-105 parts of polyvinyl chloride and 2-4 parts of a stabilizer. Viscosity of the first coating and viscosity of the second coating each range from 10000 cps to 12000 cps. The invention further relates to a preparing method of the wire-drawing screen cloth composite material. The wire-drawing screen cloth composite material can effectively solve the problem of bonding of the wire-drawing screen cloth and has the advantage of effectively improving air tightness.

Description

technical field [0001] The invention relates to wire drawing mesh technology, and its characteristics relate to a wire drawing mesh composite material and a preparation method thereof. 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. 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. The coating requires the paste to have goo...
