Problems solved by technology

[0003] In order to solve the problem of clamping parts and high noise during transportation in the prior art, the purpose of the present invention is to provide a skeleton-free conveyor belt for roller conveyors, and use thermoplastic polyurethane elastomer (TPU) with good creep resistance as the Skeletonless conveyor belt replaces the original lightweight conveyor belt fabric + polymer material composite structure. When used with a roller conveyor, a continuous plane is formed on its surface to avoid the phenomenon of jamming. At the same time, due to the continuity of the plane, it can also Reduce the noise during the conveying process, and the skeletonless conveyor belt has a certain stretching performance, which is easy to install and disassemble

preparation example Construction

[0033] The preparation method of the skeletonless conveyor belt for the above-mentioned roller conveyor comprises the following steps:

[0034] The first step: configure the conductive solution according to the ratio;

[0035] Step 2: After the polyester fabric is dried and shaped at 180-200°C, the surface is evenly coated with the above-mentioned conductive solution, and the coating density is 60-80g / m 2 ,drying;

[0036] Step 3: After uniform mixing of creep-resistant TPU material and TPU color masterbatch, extrude and cast on the surface of the above-mentioned conductive primer layer through extrusion with a melting temperature of 200-210°C, and tear off the polyester fabric after cooling and setting to obtain the product.

Embodiment 1

[0039] The conductive solution is composed of 40% carbon nanotube composite TPU masterbatch, 30% dimethylformamide and 30% methyl ethyl ketone in terms of mass percentage, and the carbon nanotube and TPU in the carbon nanotube composite TPU masterbatch The mass ratio is 1:8. , The creep-resistant TPU surface layer is a mixture of 97% creep-resistant TPU material and 3% TPU color masterbatch, and is obtained by melt extrusion casting at 200 ° C on the surface of the conductive primer layer.

Embodiment 2

[0041] The conductive solution is composed of 50% carbon nanotube composite TPU masterbatch, 25% dimethylformamide and 25% methyl ethyl ketone in terms of mass percentage, and the carbon nanotube and TPU in the carbon nanotube composite TPU masterbatch The mass ratio is 1:9, and the anti-creep TPU surface layer is a mixture composed of 98% anti-creep TPU material and 2% TPU color masterbatch, and is obtained by melt extrusion casting on the surface of the conductive primer at 210 °C .

[0042] Such as figure 1 Shown, test the variation curve of the tensile stress of the creep-resistant TPU surface material in Examples 1 and 2 with time, when the stress varies with time under the fixed extension situation, the smaller the variation with time, the better the creep resistance of the material is, It can be seen that the creep resistance of Example 1 is significantly better than that of Example 2.

Abstract

The invention discloses a skeleton-free conveyor belt for a roller conveyor and a preparation method thereof. The skeleton-free conveyor belt includes a conductive primer layer and a creep-resistant TPU surface layer, the thickness of which is 1.0-2.0mm; the conductive primer layer passes through polyester The surface of the fabric is coated with a conductive solution and then dried. The anti-creep TPU surface layer is obtained by mixing the anti-creep TPU material and TPU color masterbatch and then extruding and casting on the surface of the conductive bottom coating, including: the polyester fabric is dried and shaped Finally, the surface is uniformly coated with a conductive solution, dried, and the creep-resistant TPU surface layer is formed on the surface of the conductive primer layer by extrusion casting, and the polyester fabric is torn off. Replace the original light conveyor belt fabric + polymer material composite structure, and form a continuous plane on the surface when used with the roller conveyor, which can avoid the phenomenon of jamming and reduce the noise during the conveying process. The bottom surface adopts a conductive design, When in use, it can effectively avoid the accumulation of charge due to the high-speed conveying of the roller conveyor.

Description

technical field [0001] The invention belongs to the technical field of conveyor belt manufacture, and in particular relates to a frameless conveyor belt for a roller conveyor and a preparation method thereof. Background technique [0002] As one of the conveying equipment, the roller conveyor can be used in combination with other conveying equipment and mechanical equipment to form a large-scale automatic conveying system such as branching and merging due to its simple structure, large conveying capacity, impact resistance, stable operation, and diversified conveying methods. The industry application is more and more extensive. However, there are also certain defects in the use process, such as: the environmental noise is too large when the roller conveyor is conveying, and the small parcels are easy to get stuck when conveying. Contents of the invention [0003] In order to solve the problem of clamping parts and high noise during transportation in the prior art, the pur...
