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.

8About Ω, and cost an arm and a leg, be difficult to satisfy the needs of domestic correspondent.The antistatic load-transfer device that domestic enterprise produces adopts the mode of adding conductive black to quicken static usually and reveals, and to avoid a large amount of accumulations of static, the color of its antistatic load-transfer device product is black or light/dark balance, and color is single, and the use field is restricted; Along with the increase of carbon black addition, the pulling strengrth of PVC, strength under shock and percentage elongation etc. descend significantly, and follow hardness to rise.In addition, because the PVC load-transfer device generally adopts coating processes processing at present, the interpolation of solid materials such as carbon black makes PVC paste producing difficulty, directly influences the manufacturing of PVC load-transfer device and the final performance of product.
Domestic patent 200910201592.2 provides a kind of color antistatic PVC (Polyvinyl Chloride) conveyor belt for electronic industry, adopts to contain fatty acid monoglyceride class semi-translucent non-ionic antistatic agent, applies antistatic coating at the PVC conveyor belt surface, and its surface electrical resistance drops to 10
7-10
8Between the Ω, bottom substrate is selected the fabric of doping 5-10% conductive fiber for use, so that the leakage of static has reached certain effect.But this scheme antistatic additive consumption is big, is the 10-15wt% of PVC paste resin, and the antistatic additive degree of utilization is low.
Summary of the invention
The purpose of this invention is to provide a kind of antistatic PVC load-transfer device that is applicable to industries such as food hygiene, tobacco and electronics.
Concrete scheme of the present invention is: a kind of antistatic PVC load-transfer device, comprise bottom, laminating layer and top layer, also comprise anti-static coating and external antistatic agent coating, this load-transfer device is followed successively by external antistatic agent coating, anti-static coating, top layer, laminating layer and bottom from top to down; Wherein, top layer and bottom are to scribble the fabric that PVC sticks with paste resin, and the fabric on top layer is doped with conductive fiber at least, and anti-static coating is that the PVC that contains internal antistat sticks with paste resin coating layer.
Described anti-static coating contains: the PVC of 100 mass parts sticks with paste resin, the plasticizer of 60-80 mass parts, the stabilizer of 2-3 mass parts, the internal antistat of 4-6 mass parts.Simultaneously, can add an amount of mill base, make the color antistatic PVC load-transfer device of different colours.
As to further disclosure of the present invention, described internal antistat is a RLB-20 type antistatic additive, and described external antistatic agent is a HDC-350 type antistatic additive.
With the electrostatic leakage that accumulates in the load-transfer device, avoid accumulation of static electricity in time, the fabric on top layer is doped with conductive fiber, and described conductive fiber accounts for the 5-10% of fabric quality.
In order to improve the safe and sanitary performance of load-transfer device, described plasticizer is a polyester plasticizer, and described stabilizer is a calcium zinc heat stabilizer.
The surface electrical resistance of product of the present invention is 10
7Ω satisfies the anlistatig requirements of industry such as food hygiene, tobacco and electronics, and what add in the anti-static coating is the PVC internal antistat, be paste or liquid, slurrying process is not had influence, and it is painted not influence product, can prepares the PVC load-transfer device of different colours according to different needs.The present invention compares with external equivalents, and cost is low, has the very strong market competitiveness.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a manufacturing process flow diagram of the present invention.
The specific embodiment
Antistatic PVC load-transfer device as shown in Figure 1 is followed successively by external antistatic agent coating 1, anti-static coating 2, top layer 3, laminating layer 4 and bottom 5 from top to down, its manufacturing process as shown in Figure 2, wherein:
The base material on top layer 3 is the fabric of doping 5-10wt% conductive fiber, at first to the fabric typing, sticks with paste resin at the surperficial primary coat PVC of typing fabric; Apply the PVC that contains internal antistat at upper surface then and stick with paste resin formation anti-static coating 2, lower surface application of adhesive, the preferred Dongguan City of adhesives fly to create the PVC303 adhesives that reaches Science and Technology Ltd.'s production;
The base material of bottom 5 is selected fabric for use, at first to the fabric typing, sticks with paste resin at the surperficial primary coat PVC of typing fabric, applies the PVC303 adhesives at upper surface then;
Next a relatively hot that top layer 3 and bottom 5 is scribbled adhesives glues together, apply through external antistatic agent solution, oven dry, cooling and shaping make the antistatic PVC load-transfer device that is followed successively by external antistatic agent coating 1, anti-static coating 2, top layer 3, laminating layer 4 and bottom 5 from top to down then again.
The preparation of external antistatic agent solution: the HDC-350 type antistatic additive of selecting for use Dechang, Linan, Hangzhou chemistry Co., Ltd to produce, with volume ratio is that 1: 1 the water and the mixed liquor of isopropyl alcohol are solvent, and the massfraction that is mixed with HDC-350 type antistatic additive is the solution of 1-2%.
