Problems solved by technology

This method has two disadvantages: on the one hand, the production process is not easy to control, and there are often abnormalities such as pinholes and bubbles on the surface
On the other hand, the antistatic agent is not easy to disperse in the PVC material, which affects the overall antistatic effect.

Embodiment 1

[0026] The new production method of PVC antistatic fabric comprises the following steps:

[0027] Step (1): preparing the antistatic agent into a preparation slurry;

[0028] Step (2): Add the above-mentioned preparatory slurry to the surface treatment agent in an amount of 1-3% and stir evenly. A dispersant is added during the stirring process. The surface treatment agent is polyvinylidene fluoride or polymethyl Methyl acrylate, wherein the antistatic agent is any antistatic agent that is effectively compatible with the surface treatment agent;

[0029] Step (3): Coat the mixed solvent of the above-mentioned uniformly stirred antistatic agent preparatory slurry and surface treatment agent on the surface of the produced PVC fabric, and keep mixing in the trough through the internal circulation device during the coating process Solvent stirring. The present invention utilizes that antistatic agent can be compatible with polyvinylidene fluoride or polymethacrylic acid methyl s...

Abstract

The invention provides a novel production method of a PVC antistatic fabric. The novel production method comprises the following steps: (1), preparing an antistatic agent into a preliminary slurry; (2) adding the preliminary slurry into a surface treatment agent in an amount of 1-3% and uniformly stirring the mixture; and (3) coating the uniformly stirred mixed solvent of the antistatic agent preliminary slurry and the surface treatment agent on the surface of a produced PVC fabric. According to the novel production method provided by the invention, the antistatic agent can be compatible witha polyvinylidene fluoride or polymethyl methacrylate surface treatment agent, and the surface treatment agent can be quickly dried to form a layer of film on the surface; and this operation is simplerthan directly adding the antistatic agent to a PVC formula, the antistatic effect of a finished product is better, and uncontrollable factors in production caused by adding the antistatic agent to PVC formula are reduced.

Description

technical field [0001] The invention relates to the field of PVC antistatic fabrics, in particular to a new production method of PVC antistatic fabrics. Background technique [0002] At present, PVC polyester fiber mesh fabrics have been widely used in various industries, and some applications have anti-static requirements for fabrics, such as ventilation pipes, protective covers and rolling shutter doors. Whether it is extrusion, calendering, lamination or coating process, the traditional production method of PVC antistatic fabric is to directly add antistatic agent to PVC formula. This method has two disadvantages: on the one hand, the production process is not easy to control, and there are often abnormalities such as pinholes and bubbles on the surface. On the other hand, the antistatic agent is not easy to disperse in the PVC material, which affects the overall antistatic effect. Contents of the invention [0003] In order to solve the above-mentioned deficiencies, ...
