The invention discloses a novel stretching method TPU film manufacturing equipment, comprising an operation cabinet, an extruder, a die head, a liquid cooling mechanism, a grinding mechanism and a winding mechanism. , a die head is installed at the output end of the extruder, a cold water tank is installed inside the operation cabinet, a liquid cooling mechanism is installed at the top of the cold water tank, a guide wheel is installed in the operation cabinet, and the guide wheel is installed in the operation cabinet. A first stainless steel clamp is installed above the wheel, one side of the first stainless steel clamp is provided with a first rubber clamp, and one side of the first stainless steel clamp is provided with a grinding mechanism; the present invention prepares TPU by solution polymerization in a solvent. The characteristics of the reaction are that it is stable, uniform, and easy to control. It can obtain products with a full linear structure. The processing properties, mechanical properties and dissolution properties of the products are relatively good. The difference between the stretched TPU is its elasticity, softness, friction, permeability. Wetting, high physical and mechanical properties, and good processability. |
