Problems solved by technology

Glue has a certain degree of pollution to the environment, and the process of coating glue is complicated, and the investment in equipment is large
If the conveyor belt is used in the field of food transportation, the additives such as plasticizer and curing agent contained in the glue have certain toxicity and will pollute the food.

Embodiment 1

[0035] Such as figure 1 Shown, a kind of TPU light conveyor belt and preparation method thereof, comprise conveying base cloth 1. A TPU hot-melt adhesive film 2 is arranged on the conveying base cloth 1 , and a TPU layer 3 is arranged on the TPU hot-melt adhesive film 2 . The conveying base cloth 1, the TPU hot-melt adhesive film 2, and the TPU layer 3 are bonded together by high-temperature hot pressing. Through the above setting, compared with using glue to bond the conveying base cloth 1 and the TPU layer 3 . This bonding method can reduce the pollution caused by the volatilization of glue, and does not need to produce glue specially, which reduces the process. Since the TPU layer 3 and the TPU hot-melt adhesive film 2 belong to the same material, their bonding effect is better when bonding.

[0036] Optimally, the temperature of the high-temperature hot pressing is 120-130°C. At this temperature, compared with 160-180°C in the prior art, on the one hand, the purpose of...

Embodiment 2

[0043] like figure 2 and image 3 As shown, the difference from Example 1 is that a polypropylene layer 4 is also arranged between the TPU layer 3 and the TPU hot-melt adhesive film 2, and the same TPU hot-melt adhesive film is arranged between the polypropylene layer 4 and the TPU layer 3 2. Under high-temperature hot pressing, the TPU hot-melt adhesive film 2 on both sides of the polypropylene layer 4 melts, thereby bonding the polypropylene layer 4, the TPU layer 3 and the conveying base cloth 1 to each other. By setting the polypropylene fiber layer 4, the TPU light-duty conveyor belt has better elasticity, preventing the TPU light-duty conveyor belt from being deformed and broken due to excessive tension during the tensioning process.

[0044] Optimally, the polypropylene layer 4 is a mesh structure. By setting the polypropylene fiber layer 4 into a mesh structure, the heat dissipation capacity of the TPU light conveyor belt is improved, so that the TPU light conveyor...

Abstract

The invention discloses a TPU light conveyor belt and a preparation method thereof. The TPU light conveyor belt comprises conveying base cloth. A TPU hot melt adhesive film covers the conveying base cloth; a surface layer covers the TPU hot melt adhesive film, and the conveying base cloth, the TPU hot melt adhesive film and the surface layer are compounded together by way of high-temperature hot press. The TPU light conveyor belt disclosed by the invention has the beneficial effects that the TPU light conveyor belt uses a clean and pollution-free adhesive, so that purposes of simple process and pollution-free production process are achieved.

Description

technical field [0001] The invention relates to a light conveyor belt, in particular to a TPU light conveyor belt and a preparation method thereof. Background technique [0002] With the rapid development of industrial technology, people's requirements for environmental protection are gradually increasing. In the market of light conveyor belts, the traditional PVC conveyor belts are gradually replaced by TPU conveyor belts because of their high pollution problems. At present, the production method of TPU light-duty conveyor belts on the market is generally to coat glue on the base fabric, and then dry the glue to prevent the glue from volatilizing and polluting the surrounding environment. Finally, compound the TPU layer on the base cloth. [0003] The Chinese patent with the notification number CN103723438B discloses a wear-resistant composite TPU conveyor belt and a manufacturing method thereof, including fabric. The production method of the TPU conveyor belt is: apply ...
