Abstract
The utility model relates to an antistatic poly vinyl chloride (PVC) conveying belt which comprises an external antistatic agent coating, an antistatic coating layer, a surface layer, a bonding layer and a bottom layer which are arranged in sequence from top to bottom. The antistatic PVC conveying belt adopts a double-layer antistatic structure, surface resistance of the structure is 107ohms, accordingly antistatic requirements of industries including food sanitation, tobacco, electron and the like are satisfied, paste manufacturing technology and product coloring are not affected, and PVC conveying belts with different colors are manufactured according to different requirements. In addition, compared with foreign like products, the antistatic PVC conveying belt has low cost and strong market competitiveness.
Description
Technical field
The utility model relates to a kind of antistatic PVC load-transfer device, relates in particular to a kind of light-duty antistatic PVC load-transfer device that is applicable to industries such as food hygiene, tobacco and electronics.
Background technology
The PVC load-transfer device, is widely used in conglomerate with advantages such as its light weight, life-span length, good flame resistance, difficult generation frictions as a kind of light-duty load-transfer device.But because high-insulativity and the low water absorbable of PVC, fricative static is difficult to cancellation when carrying, and directly influences the application of product.
The surface electrical resistance of the antistatic load-transfer device of offshore company's production at present is generally 10
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.
The utility model content
The purpose of this utility model provides 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 utility model 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.
In the utility model, 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.
The utility model product adopts double-deck antistatic structure, i.e. anti-static coating and external antistatic agent coating, and surface electrical resistance is 10
7Ω satisfies the anlistatig requirements of industry such as food hygiene, tobacco and electronics, slurrying process is not had influence, and it is painted not influence product, can prepare the PVC load-transfer device of different colours according to different needs.In addition, the utility model is compared with external equivalents, and cost is low, has the very strong market competitiveness.

The specific embodiment
Embodiment 1
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 flow as shown in Figure 2, surface electrical resistance sees Table 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, its prescription is as shown in table 1, and 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%.
Table 1 anti-static coating proportioning
| Form | PVC sticks with paste resin | Plasticizer | Stabilizer | Internal antistat |
| Content (mass parts) | 100 | 65 | 1.2 | 4.4 |
Plasticizer is non-adjacent benzene nontoxic plasticizer in the table 1, is specially DX-360 type low molecular weight polyester plasticiser;
Stabilizer is the medical food rank of an environment-protecting asepsis calcium zinc heat stabilizer, is specially ZX9011 type calcium zinc heat stabilizer;
The RLB-20 type antistatic additive that internal antistat selects for use permanent auspicious large source, Beijing Science and Technology Ltd. to produce.
Comparative Examples
In order to illustrate that the utility model adopts the effect of two-layer anti-static precautions, give the Comparative Examples of independent use external antistatic agent and internal antistat, the consumption of its antistatic additive is identical with embodiment 1, and surface electrical resistance sees Table 2.
As can be seen from Table 2, effect is the poorest when using external antistatic agent separately, and conveyor belt surface resistance is 3.9 * 10
9Ω, when using internal antistat separately, the surface electrical resistance of load-transfer device can reach foreign level, is 4.2 * 10
8Ω, when two kinds of antistatic additive used simultaneously, the surface electrical resistance of load-transfer device reduced to 4.0 * 10
7Ω.
Surface electrical resistance when two kinds of antistatic additive of table 2 use separately
Annotate: size of sample is 300mm * 300mm, and temperature is 25 ℃, and relative humidity is 65%.
