Problems solved by technology
At present, the traditional method is to add silicon-containing additives to the TPU material, which has a certain effect on improving the wear resistance of the conveyor belt, but the compatibility of silicon-containing materials in TPU is relatively poor, and it is easy to migrate to the surface of the TPU, affecting the wear resistance of the conveyor belt. The bonding between TPU and polyester fabric will not only separate TPU from polyester fabric during use, but also cause separation between TPU layers. The extension of time decreases, so it is of great significance to find new wear-resistant materials

Embodiment Construction
[0019] A wear-resistant composite TPU conveyor belt includes a TPU conveyor belt, and a nylon 12 film is respectively coated on the surface layer and the bottom layer of the TPU conveyor belt.
[0020] The specific production process is:
[0021] The first step: the polyester fabric is qualitatively heated in a far-infrared oven, and the processing temperature is 180-200°C;
[0022] The second step: PU glue primer on the front of the fabric, the processing temperature is 120°C--150°C;
[0023] The third step: PU glue primer on the reverse side of the fabric, the processing temperature is 120°C--150°C;
[0024] Step 4: The reverse side of the fabric is primed with nylon 12 (PA12) powder with a fineness of 320 mesh, a thickness of 0.1mm, and a processing temperature of 180-200°C;
[0025] Step 5: Calender the TPU layer on the front of the fabric, the processing temperature is 200-210°C, and the composite pressure is 15-20Pa. During the process, the temperature of the fabric su...

The invention discloses a wear-resistant composite TPU (Thermoplastic Polyurethane) conveying belt. The wear-resistant composite TPU conveying belt comprises a TPU conveying belt, wherein the surface layer and the bottom part of the TPU conveying belt are respectively coated with a layer of nylon film. A preparation method of the conveying belt comprises the following steps in sequence: sizing fabric, carrying out undercoating of glue on the front surface of the fabric, carrying out undercoating of the glue on the back surface of the fabric, coating the back surface of the fabric with a nylon layer, calendering a TPU layer on the front surface of the fabric, and calendering the nylon layer on the TPU layer to obtain the finished product, wherein the back surface of the fabric is undercoated with 320-mesh PA12 powder which is 0.1mm thick, and the processing temperature is 180-200 DEG C; when the PA layer is calendered on the TPU layer, the processing temperature is 180-190 DEG C and the composite pressure is 15-20Pa; in the calendering process, the temperature of the TPU layer is maintained at 160-180 DEG C. The wear-resistant composite TPU conveying belt disclosed by the invention has the advantages that the wearing resistance of the surface layer of the conveying belt is improved; the bonding performance between the surface layer and the fabric is improved; the same abrasion resistance is maintained in use of the whole conveying belt; the wearing resistance of the back surface of the fabric is improved and the friction coefficient is reduced.
Description
technical field [0001] The invention relates to the technical field of manufacturing light-duty conveyor belts, in particular to a wear-resistant composite TPU conveyor belt and a manufacturing method thereof. Background technique [0002] TPU light conveyor belt generally uses polyester fabric as the skeleton material, and is mainly used for conveying light and medium quality materials. TPU light-duty conveyor belts are widely used in logistics, airports, postal services, entertainment and fitness industries due to their light weight, easy installation, and less friction. [0003] Due to the environmental problems of the TPU light-duty conveyor belt, the surface of the belt body and the bottom of the product are easily worn during use, which will greatly reduce the service life of the conveyor belt. At present, the traditional method is to add silicon-containing additives to the TPU material, which has a certain effect on improving the wear resistance of the conveyor belt,...
