Problems solved by technology
At present, traditional double-sided coated TPU composite cloth products adopt intermittent casting production technology. After one-sided tape-casting and compounding, the reverse side is cast and compounded again. The melt and the compound cloth are compounded at low pressure, which has weak permeability and low production efficiency. Peel strength below 30N / 2.5cm

Abstract
The invention discloses a material extruding and coating device for synchronously and highly stripping TPU (Thermoplastic Polyurethane) compound cloth from two sides. The material extruding and coating device comprises a symmetric type double-layered compound mould head and TPU material extruding mechanisms, wherein the symmetric type double-layered compound mould head comprises two sub mould bodies which are symmetrical to each other up and down; each sub mould body is provided with a feeding channel communicated with a compound channel; two sets of the TPU material extruding mechanisms are arranged; each set of the TPU material extruding mechanism comprises a TPU extruding machine and a melt pump connected with a discharging end of the TPU extruding machine; and discharging ends of the melt pumps of the two sets of the TPU material extruding mechanisms are respectively communicated with the feeding channels on the two sub mould bodies. The material extruding and coating device disclosed by the invention has the advantages that the production efficiency is high; the material extruding efficiency of TPU extruding machines and the material supplying pressure of the melt pumps are accurately controlled according to the requirements of a coating process; and the material extruding and coating device guarantees that TPU melts can effectively penetrate through woven cloth, and the effect of improving the stripping strength is improved.
Description
technical field [0001] The invention belongs to the field of TPU extrusion molding processing, and specifically refers to a synchronous double-sided high-peeling TPU composite cloth compounding device and a production process thereof. Background technique [0002] TPU (thermoplastic polyurethane elastomer) is an environmentally friendly material that is non-toxic and harmless, and will not produce secondary pollution. It can be recycled and reused many times. In 2-3 years, it can be automatically degraded and decomposed into carbon dioxide and water that are harmless to humans. The significance is that it can partially replace non-environmental protection materials such as PVC and is widely used in all aspects of people's lives. At present, traditional double-sided coated TPU composite cloth products adopt intermittent casting production technology. After one-sided tape-casting and compounding, the reverse side is cast and compounded again. The melt and the compound cloth ar...
