specific Embodiment approach 1

[0007] Specific implementation mode 1: In this embodiment, the multi-layer co-extruded gas-phase anti-rust film has a three-layer, five-layer or seven-layer structure; the multi-layer co-extruded gas-phase anti-rust film has a three-layer structure, and each layer from the inside to the outside is A / B / G; multi-layer co-extruded vapor phase anti-corrosion film has a five-layer structure, and each layer from the inside to the outside is A / B / D / B / G, A / B / C / B / G or A / B / C / D / G; multi-layer co-extruded vapor phase antirust film is a seven-layer structure, and each layer from the inside to the outside is A / B / C / D / C / B / G or A / B / C / D / E / F / G; the material of the A layer is a mixture of 80% to 95% (mass) polyolefin and 5% to 20% (mass) gas phase rust inhibitor or 80% to 95% (mass) polyamide and 5% to 20% (mass) % (mass) of a mixture of vapor phase antirust agents, the material of the B layer is a mixture of 90% to 98% (mass) of an adhesive and 2% to 10% (mass) of a gas phase antirust agent, a...

specific Embodiment approach 2

[0010] Embodiment 2: This embodiment is different from Embodiment 1 in that the polyolefin is polypropylene (abbreviated as PP), polyethylene (abbreviated as PE) or chlorinated polyethylene (abbreviated as EVA). Others are the same as in the first embodiment.

specific Embodiment approach 3

[0011] Embodiment 3: The polyester described in this embodiment and the specific embodiment is ethylene methyl acrylate copolymer (abbreviated as EMA) or ethylene acrylic acid copolymer (abbreviated as EAA).

Abstract

The invention relates to a multi-layer co-extrusion volatile rust-proof film, belonging to the field of plastic films. To solve the technical problem of short rust-proof time at low temperature in the current volatile rust-proof film, the multi-layer co-extrusion volatile rust-proof film is provided. The multi-layer co-extrusion volatile rust-proof film provided by the invention has a multi-layer structure. The multi-layer co-extrusion volatile rust-proof film is in a three-layer, five-layer or seven-layer structure, wherein the multi-layer co-extrusion volatile rust-proof film is in a three-layer structure including A/B/G from inside to outside; or the multi-layer co-extrusion volatile rust-proof film is in a five-layer structure including A/B/D/B/G, A/B/C/B/G or A/B/C/D/G from inside to outside; or the multi-layer co-extrusion volatile rust-proof film is in a seven-layer structure including A/B/C/D/C/B/G or A/B/C/D/E/F/G from inside to outside. The rust-proof effect of the multi-layer co-extrusion volatile rust-proof film provided by the invention can be up to 10-20 years.

Description

technical field [0001] The invention belongs to the field of plastic films. Background technique [0002] Vapor phase anti-rust film is a kind of metal anti-rust plastic film that has gradually emerged in recent years. Before that, the general anti-rust mostly relied on oiling, painting, etc. Rust paper, since the advent of gas-phase anti-rust film products, has been widely recognized by the society. These products, one is a product with a gas-phase anti-rust agent added to a single-layer polyethylene material, and there is an outer layer of plastic film, an inner layer Dry composite film with gas phase antirust film, and two layers of plastic film dry compounded together (PA) film and polyethylene film with gas phase layer, and two or three layers of polyethylene type Heat-shrinkable films, these films have played a positive role in market applications. Their anti-rust effect can basically last for one, two, five or eight years, but they are still unsatisfactory as high-ef...
