Manufacturing process of TPU waterproof film

Abstract

The invention discloses a manufacturing process of a TPU waterproof film. The manufacturing process comprises the following manufacturing steps of S1, pretreatment: cleaning all processing raw materials, maintaining the cleanliness of the raw materials, and charging the raw materials in a sealed container for temporary storage; and S2, classification proportioning: classifying, weighing and proportioning all processing raw material plastic particles, and placing the plastic particles in a feeding area to wait for feeding. A coating compounding step is added to the manufacturing process. An antistatic carbon coating is adopted as the main raw material and is compounded on a semi-finished TPU film through compounding and hot pressing, so that the TPU film has both the waterproof effect and the antistatic effect and can effectively prevent excessive static electricity from breaking through the film during application. The TPU waterproof film is high in functionality, meets more demands ofusers during application and has high practicality.

Description

technical field [0001] The invention relates to the field of film technology, in particular to a manufacturing process of a TPU waterproof film. Background technique [0002] A film is a thin and soft transparent sheet made of plastic, adhesive, rubber or other materials. The scientific explanation of a film is: a two-dimensional material formed by depositing atoms, molecules or ions on the surface of a substrate, for example: Optical film, composite film, superconducting film, polyester film, nylon film, plastic film, etc., the film is widely used in electronic appliances, machinery, printing and other industries. [0003] Most of the TPU waterproof films currently on the market have a single function in the application process, and often only have a separate waterproof function, which cannot meet the different needs of users when used, and there are certain limitations when used. When the TPU waterproof film encounters strong static electricity during the application proc...

Problems solved by technology

[0003] Most of the TPU waterproof films currently on the market have a single function in the application process, and often only have a separate waterproof function, which cannot meet the different needs of users when used, and there are certain limitations when used. When the TPU waterproof film encounters strong static electricity during the application process, it is easy to break down the film due to static electricity, and the antistatic effect cannot be achieved, so it is more troublesome to apply.
