Example Embodiment

[0020] The composite tarpaulin with high peel strength includes a woven mesh cloth and two layers of TPU films. Both sides of the woven mesh cloth are coated with a layer of PUR glue, and the inner side of the TPU film is coated with a layer of PUR glue. Second, the PUR glue layer 1 and the PUR glue layer 2 are connected together by hot roller pressing.

[0021] Further, the thickness of the first PUR glue layer is 0.07mm.

[0022] Further, the thickness of the second PUR glue layer is 0.05mm.

[0023] Further, the thickness of the TPU film is 0.08mm.

[0024] The invention also discloses a method for producing a composite tarpaulin with high peel strength, which specifically includes the following steps:

[0025] 1. Release the woven mesh cloth on the first unwinding roller, and release the TPU film on the second unwinding roller;

[0026] 2. Apply the PUR glue on the front of the woven mesh cloth through the gluing mechanism to form the PUR glue layer 1, and apply the PUR...

Abstract

The invention provides a composite tarpaulin with high peel strength and a production method thereof, the composite tarpaulin comprises a woven gridding cloth and two layers of TPU films, both sides of the woven gridding cloth are coated with a layer of PUR glue layer I, the inner side of each TPU film is coated with a layer of PUR glue layer II, and the PUR glue layers I and the PUR glue layers II are connected together through hot roller pressing. The woven gridding cloth and the TPU film are both coated with the PUR glue layers, and the two PUR glue layers can be perfectly fused and bonded together during bonding, so that the whole composite tarpaulin has high peel strength and is not easy to tear and separate.

Description

technical field [0001] The invention belongs to the technical field of high-performance composite materials, and relates to a composite tarpaulin with high peel strength and a production method thereof. Background technique [0002] The current tarpaulins are composited by hot pressing, but the existing composites are all coated with a single layer of glue, which requires the glue on the composite machine to be coated on the woven mesh cloth or composite film, and because some special fibers are woven The woven mesh material has special properties, which cause unevenness and easy peeling during the film compounding process, which affects the performance of the product. SUMMARY OF THE INVENTION [0003] The object of the present invention is to solve the above-mentioned problems in the existing technology, and propose a composite tarpaulin with high peel strength and a production method thereof. The composite tarpaulin manufactured by this production method has ultra-high p...
