Problems solved by technology

However, in many applications, when the surface of the TPU film is generated and accumulated due to friction, peeling or induction processes, these characteristics will cause serious potential hazards, such as dust absorption, electric shock, discharge or even combustion and explosion.

Embodiment 1

[0023] Such as figure 1 As shown, the antistatic TPU film includes a first conductive layer 1 , a TPU base layer 2 , a second conductive layer 3 , and a wear-resistant layer 4 from bottom to top.

[0024] The thickness of the first conductive layer 1 is 10 μm, and the surface resistivity is 1×10 4 Ω; the thickness of the TPU base layer 2 is 100 μm, the thickness of the second conductive layer 3 is 10 μm, and the surface resistivity is 1×10 4 Ω; the thickness of the wear-resistant layer 4 is 10 μm.

[0025] The first conductive layer 1 and the second conductive layer 3 are each a TPU layer with carbon nanotubes attached; the wear-resistant layer 4 is a TPU layer with an anti-friction agent attached.

[0026] Antistatic TPU film is made by the following method:

[0027] (1) Make the first conductive masterbatch that is added with carbon nanotube: get TPU matrix material and carbon nanotube, the addition amount of carbon nanotube is 5%, wherein also can add additives such as l...

Abstract

The invention discloses an antistatic TPU (Thermoplastic Polyurethane) film. The antistatic TPU film sequentially comprises a first conducting layer, a TPU base layer, a second conducting layer and a wear-resisting layer from bottom to top, wherein the first conducting layer and the second conducting layer are TPU layers to which carbon nanotubes are attached; the wear-resisting layer is a TPU layer to which an abrasive agent is attached. According to the antistatic TPU film disclosed by the invention, the conducting layers are respectively arranged on two surfaces of a base material, so that static electricity on the two surfaces of the TPU film can be eliminated; when the antistatic TPU film is used for packaging materials, the operation is realized more easily, potential hazards such as electric shock and discharge caused by static electricity accumulation can be prevented, and pollution, dust and the like caused by the static electricity accumulation can be also prevented. The wear-resisting layer is arranged on the surface of the TPU film, so that a wear-resisting coefficient of the film can be reduced, and the durability of the film is improved.

Description

technical field [0001] The invention relates to an antistatic TPU film. Background technique [0002] TPU is a polymer material formed by co-reacting diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with macromolecular polyols and low molecular polyols (chain extenders). Its molecular structure is a rigid block obtained by reacting diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with a chain extender and diisocyanates such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) Molecules and macromolecular polyols react to form flexible segments alternately. TPU has excellent characteristics of high tension, high tensile strength, toughness and aging resistance, and is a mature environmental protection material. At present, TPU has been widely used in medical and health, electronic appliances, industry and sports, etc. TPU film is an important application form of TPU material. In recent years, it h...
