Problems solved by technology

Because static electricity will cause damage or breakdown to electronic equipment, such as: the line will be broken down after the static electricity is adhered to by ashes; the discharge breakdown will directly damage the integrated circuits and digital devices in the circuit board, etc.
However, as time goes by, the antistatic agent coated on the outside may fail, and its antistatic effect is unstable.

Abstract

The invention relates to the technical field of military protection, in particular to a PVDC high-barrier co-extrusion self-adhesive film for military protection and a preparation method thereof. The PVDC high-barrier co-extrusion self-adhesive film is composed of an outer layer, a first adhesive layer, a PVDC layer, a second adhesive layer, a secondary inner layer and an inner layer which are sequentially arranged. The outer layer is composed of linear low-density polyethylene, low-density polyethylene, modified graphene and an additive, and the secondary inner layer is composed of linear low-density polyethylene, low-density polyethylene, metallocene polyethylene and an additive. The co-extrusion film can be used for military protection and dust prevention, and the possibility that dust generates static electricity and a low-intensity magnetic field is generated is avoided; the water vapor transmission rate reaches about 1g / cm * 24h, and the moisture-proof effect is excellent; and the pressure-resistant stability is high.

Description

technical field [0001] The invention relates to the technical field of military industry protection, in particular to a PVDC high-barrier co-extruded self-adhesive film for military industry protection and a preparation method thereof. Background technique [0002] In the field of military protection, it is necessary to protect electronic products such as electronic equipment, electronic devices, and digital devices. The common practice is to brush a layer of PET antistatic agent on the surface of the electronic protective film to form a very Thin conductive layer, improve surface conductivity, make the generated charge leak as soon as possible, reduce the threat of static electricity, and prevent static electricity during operation, transportation and storage. Because static electricity will cause damage or breakdown to electronic equipment, such as: the line will be broken down after the static electricity is attached by ashes; the discharge breakdown will directly damage ...
