Embodiment Construction

[0014] like figure 1 The shown antistatic PVC conveyor belt, from top to bottom, is an external antistatic agent coating 1, an antistatic coating layer 2, a surface layer 3, a bonding layer 4 and a bottom layer 5, and its manufacturing process is as follows figure 2 shown, where:

[0015] The base material of the surface layer 3 is a fabric doped with 5-10wt% conductive fibers. First, the fabric is shaped, and the surface of the shaped fabric is primed with PVC paste resin; then the upper surface is coated with PVC paste resin containing an internal antistatic agent to form Antistatic coating layer 2, the lower surface is coated with adhesive, and the adhesive is preferably PVC303 adhesive produced by Dongguan Feichuangda Technology Co., Ltd.;

[0016] The base material of the bottom layer 5 is made of fiber fabric, first the fabric is shaped, the surface of the shaped fabric is primed with PVC paste resin, and then the upper surface is coated with PVC303 adhesive;

[0017]...

Abstract

The invention relates to an antistatic poly vinyl chloride (PVC) conveyer belt. The conveyer belt sequentially comprises an external antistatic agent coating, an antistatic coating layer, a surface layer, a laminated layer and a bottom layer from top to down, wherein the surface layer and the bottom layer are fabrics coated with PVC paste resin, at least the fabric of the surface layer is doped with conductive fibers, and the antistatic coating layer is a PVC paste resin coating layer containing an internal antistatic agent. The surface resistance of the antistatic PVC conveyer belt is 107ohms, so the requirements of the food hygiene, tobacco, electronics and other fields on static resistance are melt, and no influence on a paste making process and product coloring is exerted because the internal PVC antistatic agent in a paste or liquid state is added into the antistatic coating layer. Moreover, different-color antistatic PVC conveyer belt can be made according to different demands.

Description

technical field [0001] The invention relates to an antistatic PVC conveyor belt, in particular to a light antistatic PVC conveyor belt suitable for industries such as food sanitation, tobacco and electronics. Background technique [0002] As a light conveyor belt, PVC conveyor belt has been widely used in many industries due to its advantages of light weight, long life, good flame retardancy, and less friction. However, due to the high insulation and low water absorption of PVC, the static electricity generated by friction during transportation is difficult to eliminate, which directly affects the application of the product. [0003] At present, the surface resistance of the antistatic conveyor belt produced by foreign companies is generally 10 8 Ω or so, and the price is expensive, it is difficult to meet the needs of domestic customers. Antistatic conveyor belts produced by domestic companies usually add conductive carbon black to accelerate static leakage to avoid a lar...
