A double-layer plastic film having a thermally insulating gap structure

Abstract

A double-layer plastic film having a thermally insulating gap structure is disclosed. The double-layer plastic film includes an upper plastic film layer in which first thermally insulating layers areequally spaced. The upper surface of the upper plastic film layer is tightly attached to a waterproof layer, and the lower surface of the upper plastic film layer is tightly attached to a plastic baselayer. A separating film is clamped and connected in each adhesive slot. The upper end of aerogel is adhered to upper shock absorbing balls, and the lower surfaces of the upper shock absorbing ballsare provided with sticky rubber the lower end of which is adhered to lower shock absorbing balls. The external surfaces of the upper and lower shock absorbing balls are provided with phenolic foam under which a lower plastic film layer is arranged. The lower left and right sides of the lower plastic film layer are provided with lower clasps. The double-layer plastic film has good thermal insulation performance and good waterproofness, is provided with sufficient damping parts, is not liable to tear or break and is relatively stable in inner structure.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a double-layer plastic film with a thermal insulation gap structure. Background technique [0002] Traditional thermal insulation covering materials, including grass thatch, cattail mats, paper quilts and cotton quilts, etc., are easily soaked by rain and snow, which not only increases the weight, but also reduces the thermal insulation performance. At present, it is widely used in agriculture, animal husbandry and aquaculture. The ordinary thermal insulation film widely used in the industry generally has poor mechanical strength, weak wind resistance and snow resistance, is easy to age and tear, and has poor thermal insulation effect and is easy to hang water droplets. A great problem has come. The general double-layer plastic film has poor thermal insulation effect, poor waterproof performance, no certain cushioning effect, and is easily torn and damaged by the impact of ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a double-layer plastic film with a thermal insulation gap structure, which solves the problem of poor thermal insulation effect, poor waterproof performance, no certain buffering effect and easy tearing when hit by components such as ice and snow. , damage, internal structure is not stable enough
