Description

PVC dryer cloth surface antistatic structure

Technical Field

The utility model relates to the technical field of PVC (polyvinyl chloride) air duct cloth, in particular to an antistatic structure on the surface of the PVC air duct cloth.

Background

The PVC material is usually adopted as the air duct cloth, the PVC is a cheap polymer material, the flame retardant property is good, the surface resistance is 1012 ohms, and the PVC material can be conveniently manufactured into a flexible film to meet the production and processing requirements of the air duct cloth, so that the problem to be solved is the antistatic property of the surface. The prior art is an internal addition method, namely, an antistatic material and other auxiliary agents are mixed before the PVC film is molded and processed, so that the material body has an antistatic function.

Currently, the internal addition is divided into the following three types, and the manufacturing principle and the defects are as follows:

1. surfactant plus antistatic agent method: the principle is to add liquid antistatic agent to PVC powder. After calendaring to form a film, the film is uniformly dispersed in the body, and the antistatic agent is enriched towards the surface along with the migration of the plasticizer, so that the antistatic property is generated on the surface. The method has the defects of unstable surface antistatic performance, short service life, water-soluble micromolecules of the antistatic agent, easy rain washing and wet wiping after migrating to the surface, and removal of the antistatic agent, so that long-acting antistatic effect is difficult to maintain.

2. Conductive carbon black filling method: the principle is that more than 8 percent of special conductive carbon black is added into PVC powder, uniformly mixed and then calendared into a film, and the conductive carbon black is uniformly distributed in a body, so that the surface of the PVC powder has antistatic performance. However, due to the specificity of the conductive carbon black, only a small number of manufacturers for producing the carbon black exist in China, the price is high, and certain environmental pollution is brought in the production process. This approach also suffers from two major drawbacks: 1. the conductive carbon black is inflammable, so that the flame retardant property and smoke suppression property of the product are damaged, and particularly, the flameless combustion of the product can not reach national regulations; 2. because a large amount of conductive carbon black is added into the PVC material, the mechanical index of the PVC air duct cloth is greatly reduced, and the service life of the product is shortened.

3. Mixing method: the two antistatic materials are respectively halved and mixed in PVC powder, and are calendered into a film, but the film cannot meet the standard requirement after film formation, and the defects cannot be overcome.

Therefore, the design practicality is strong and the traditional mode of adding antistatic agent in dryer cloth material is changed, just can set up antistatic structure at dryer cloth surface, when satisfying its antistatic requirement, avoid the cost of manufacture to improve by a wide margin, and can not destroy the excellent fire resistance and the anticorrosive that PVC dryer cloth itself had, the mechanical index on surface can obtain the antistatic structure in PVC dryer cloth surface that promotes.
