Problems solved by technology

[0002] At present, there is no suitable packaging material for long-term storage packaging of heavy machinery, automobiles and other mechanical equipment. Although fabrics are used to reinforce antirust paper or canvas and other packaging materials, there are obvious deficiencies, and the functions are relatively single. Defects such as moisture and oil absorption reduce the effect of anti-rust packaging and affect the anti-rust function of the product
In the process of storage and transportation, it is easy to cause corrosion of equipment and machinery

Abstract

The invention provides a compound antirust packaging material and a manufacturing method thereof, belonging to the technical field of packaging materials. The compound antirust packaging material is formed by compounding three layers of structures, namely an inner layer of wood pulp spunlace non-woven fabric with functions of condensed water prevention and buffering, a middle hot melt adhesive layer providing gas phase antirust technology and having an adhering function, and an outer layer of high polymer thermal contraction thin film with functions of thermal contraction and aging prevention. When the compound antirust packaging material is manufactured, a thermal contraction thin film and a spunlace non-woven fabric are compounded together by solvent-free hot melt adhesive in an adhering manner. By utilizing the non-corrosiveness non-woven fabric as a base material, the compound antirust packaging material has functions of condensed water prevention and buffering; and by virtue of a thermal contraction process after a packaging process, a package material and a packaged object can be combined to form a whole effectively, and the outer thermal contraction layer and the middle hot melt adhesive layer can release a large amount of VCI (volatile corrosion inhibitor), and air pressure coated on the inner layer is increased at the same time, and thereby a better antirust effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a composite anti-rust packaging material and a manufacturing method. Background technique [0002] At present, there is no suitable packaging material for the long-term storage packaging of heavy machinery, automobiles and other mechanical equipment. Although the packaging materials such as anti-rust paper or canvas are reinforced with fabrics, there are obvious deficiencies, and the functions are relatively simple. Defects such as moisture and oil absorption reduce the effect of anti-rust packaging and affect the anti-rust function of the product. It is easy to cause corrosion of equipment and machinery during storage and transportation. It is inevitable to research a new type of multi-functional composite anti-rust packaging material with anti-aging, anti-condensation, thermal shrinkage and gas-phase anti-rust technologies.
