Description

Glass fiber reinforced PVC transparent film

Technical Field

The utility model relates to the technical field of PVC films, in particular to a glass fiber reinforced PVC transparent film.

Background

The PVC mainly contains polyvinyl chloride, is yellowish, semitransparent and glossy. The transparency is better than that of polyethylene and polypropylene, is different from that of polystyrene, is divided into soft and hard polyvinyl chloride according to different using amounts of the auxiliary agents, soft products are soft and tough, the hand feeling is sticky, the hardness of hard products is higher than that of low-density polyethylene and lower than that of polypropylene, and the whitening phenomenon can occur at the bending position.

In use, the main problems of PVC films are: (1) the PVC film has low tensile strength and high elongation, is easy to deform and tear, and reduces the use quality of the PVC film; (2) the PVC film does not have the sound insulation effect, and is not suitable for being used in some sound insulation occasions, so that the application range of the PVC film is narrowed.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a glass fiber reinforced PVC transparent film, aiming at solving the problems in the background technology.

The technical scheme of the utility model is as follows:

glass fiber reinforced PVC transparent film, its characterized in that: it includes the diaphragm body, first enhancement layer, second enhancement layer, first puigging, sound absorbing layer and second puigging, the top surface of diaphragm body bonds and has first enhancement layer, the top surface of diaphragm body bonds and has the second enhancement layer, the top surface of first enhancement layer bonds and has first puigging, the top surface of first puigging bonds and has sound absorbing layer, sound absorbing layer's top surface bonds and has the second puigging, sound absorbing layer's inside is provided with scattered sound structure, scattered sound structure is including scattered sound hole and scattered sound groove, sound absorbing layer's inside is provided with a plurality of scattered sound hole, sound absorbing layer's inside is provided with scattered sound groove, scattered sound groove and scattered sound jogged joint.

Furthermore, the film body is a PVC adhesive film.

Further, the first reinforcing layer and the second reinforcing layer are both glass fiber cloth layers.
