A kind of composite radiation refrigeration film production method

Abstract

The invention relates to the technical field of refrigerating film manufacturing, in particular to a method for producing a composite radiation refrigerating film, comprising a placing plate, a transmission part and a cutting part; The upper end of the piece is jointly installed with a cutting piece. In the existing method, when removing the excess glue on both sides of the refrigeration film, the sides of the refrigeration film are usually cut off directly, but the existing equipment cannot clamp the two sides of the refrigeration film, and the refrigeration film is easy to be cut during the cutting process. Deformation occurs, resulting in uneven incision at the cutting place of the refrigeration film, thereby reducing the aesthetics of the refrigeration film. The cutting mechanism adopted in the production method of the composite radiation refrigeration film provided by the present invention can clamp the cutting part of the refrigeration film, so that the incision of the refrigeration film is flat and smooth, and the aesthetics of the refrigeration film after being formed is ensured.

Description

technical field [0001] The invention relates to the technical field of refrigerating film manufacturing, in particular to a method for producing a composite radiation refrigerating film. Background technique [0002] The composite radiation cooling film can be directly pasted on the outer surface of the structure that needs lighting, such as window glass, curtain wall glass, skylight glass, etc. The composite radiation cooling film has an atmospheric window emissivity of more than 90%, which enables the structure to continuously transfer heat to the space low temperature source , to achieve cooling; at the same time, the reflected solar energy is maximized while ensuring the light transmittance requirements, ensuring that the structure has less heat and enhancing the cooling effect. [0003] The composite radiation cooling film is divided into an upper release layer, a self-cleaning layer, a radiation cooling film, a protective layer and a lower release layer, and the self-c...

AI Technical Summary

Problems solved by technology

[0003] The composite radiation cooling film is divided into an upper release layer, a self-cleaning layer, a radiation cooling film, a protective layer and a lower release layer. The self-cleaning layer and the radiation cooling film are connected by glue. When the excess glue on the side is removed, the side of the cooling film is usually cut off directly. This method is simple and effective, but the existing equipment cannot clamp the two sides of the cooling film when cutting off both sides of the cooling film. The cooling film It is easy to deform during the cutting process, resulting in uneven cutting of the cooling film, thus reducing the aesthetics of the cooling film forming

[0004] Existing equipment cannot scrape off the sticky glue on the equipment when cutting both sides of the refrigeration film. With the cutting of the refrigeration film, the glue accumulated on the equipment will affect the movement of the refrigeration film, and the accumulated glue will It is easy to stick to the surface of the refrigeration film, which reduces the stability of the refrigeration film degumification
