Anti-static film and preparation method thereof

Abstract

The invention relates to the field of adhesive films, and particularly discloses an anti-static film and a preparation method thereof. The anti-static film comprises an adhesive layer, a base material, an anti-static layer and an isolating layer which are sequentially arranged. Conductive filler of the anti-static layer plays a role in static leakage, and meanwhile a current channel is formed between aniline tripolymer of the anti-static layer and poly (6-carboxyindole) of the isolation layer, so that static charges on the surface of the isolation layer are rapidly transferred to the anti-static layer from the isolation layer, and the anti-static film has a good anti-static effect. When the anti-static film is used on the inner wall of a paint spraying workshop, the possibility of explosion of the paint spraying workshop is reduced. The preparation method comprises the following steps of: hot-pressing the base material to form a film, carrying out corona treatment on the surface, forming an adhesive layer on one surface, forming an anti-static layer on the other surface, and finally forming an isolation layer on the surface, far away from the adhesive layer, of the anti-static layer.

Description

technical field [0001] The application relates to the field of adhesive films, more specifically, it relates to an antistatic film and a preparation method thereof. Background technique [0002] Electrostatic hazards in the painting industry are the main hazards: when spraying paint, paint splashes on the walls of the workshop, which is prone to static electricity accumulation, ignites the paint attached to the inner wall of the workshop and the paint piled up in the workshop, resulting in a violent explosion in the painting workshop. [0003] At present, in order to reduce the possibility of explosion in the painting workshop, the commonly used measure is to wash the inner wall of the workshop with clean water, so that the waste paint is peeled off from the inner wall of the workshop, and there is a water film on the inner wall of the workshop, and the static electricity is removed by leakage. This method has the following defects: first, the operation of washing with clear...

Problems solved by technology

[0003] At present, in order to reduce the possibility of explosion in the painting workshop, the commonly used measure is to wash the inner wall of the workshop with clean water, so that the waste paint is peeled off from the inner wall of the workshop, and there is a water film on the inner wall of the workshop, and the static electricity is removed by leakage. This method has the following defects: first, the operation of washing with clear water is cumbersome, and the waste paint on the inner wall of the workshop needs to be washed many times to remove the waste paint on the inner wall of the workshop. Secondly, the water film is easy to dry and lose, and the anti-static effect is not good
