Problems solved by technology

The envelope material is generally thick and has poor flexibility. It is difficult to construct the equipment when packaging the equipment, and the material is prone to delamination.
In addition, if the high barrier layer in the envelope is aluminum foil, the folding and bending during use will easily cause cracks in the aluminum foil, which will reduce the barrier and storage performance. In addition, the envelope material is made of multiple materials, which makes it difficult to recycle after use.

Abstract

The invention discloses an antirust packaging material and a preparation method thereof. The antirust packaging material comprises the following components in parts by weight: 50-100 parts of a thermoplastic or elastomer polymer base material and 0.1-50 parts of an active material, wherein the active material comprises one or more of metal micro-powder, metal oxide micro-powder and carbon micro-powder. The thermoplastic or elastomer polymer base material and the active material are used as main raw materials, the prepared antirust packaging material has the advantages of no gas volatilization,long-term protection, visible failure, recyclability, easiness in recovery and the like; moreover, the prepared antirust packaging material not only can be suitable for protection of various preciousmetal materials including copper, nickel and silver and ferrous metal materials mainly including iron and steel, but also can be used for long-term protection of electronic devices, electromechanicalautomation equipment and high-end intelligent equipment containing various metal materials.

Description

technical field [0001] The invention relates to the field of antirust packaging materials, in particular to a non-gas phase active antirust packaging material and a preparation method thereof. Background technique [0002] Metal iron, copper, silver and nickel and their various alloys are extremely widely used in the industrial field, and these metals are vulnerable to the threat of corrosion whether they are used as metal raw materials, metal parts in processing workshops or various processed metal parts, And rust changes the appearance of the metal, degrades its performance, and affects the further processing and performance of metal parts. [0003] In the prior art, metal antirust protection is generally carried out by VCI (Volatile Corrosion Inhibitor) packaging. The VCI used in the VCI packaging is a volatile substance, volatile molecules Concentration on the metal surface can play a significant anti-rust effect. However, traditional gas-phase antirust agents mostly u...
