A kind of preparation method of packaging material

Abstract

The invention provides a preparation method of a packaging material. The method comprises the following steps that 1, blade coating is conducted on a protective layer through a scraper till the face of a bearing layer is reached, and drying is conducted after blade coating; 2, blade coating is conducted on an antirust layer through the scraper till the other face of the bearing layer is reached; 3, the antirust layer is attached with a moisture absorbent and quick-dry layer, and drying is conducted after attaching, wherein the bearing layer is a fabric a, the moisture absorbent and quick-dry layer is a fabric b, and the the first step and the second step can be conducted randomly. According to the preparation method of the packaging material, the defects in the prior art are overcome, the technology is simple, for the prepared packaging material, an antirust agent can be volatilized at room temperature, mechanical equipment is prevented from rusting, harm of sunshine, rain and snow can be avoided simultaneously, and the protective time is long.

Description

technical field [0001] The invention belongs to the field of packaging and protection of mechanical equipment, and in particular relates to a preparation method of a packaging material. Background technique [0002] Some large-scale construction machinery equipment, precision instruments, precious metal materials and automobiles, etc., cannot be moved or cannot be transferred in time under rain, snow, hot and humid weather or harsh environments, such as excavators during automobile transportation and construction etc. At this time, they are often damaged by the external environment, especially in rainy and snowy weather, they are often corroded. However, the mechanical packaging materials in the prior art can only function as a barrier to rain and air. In a humid environment, the corrosion resistance of mechanical equipment cannot be guaranteed. Once these large equipment rust, the value will be greatly reduced, and even affect the quality of the equipment. Normal use. How...

Problems solved by technology

However, the mechanical packaging materials in the prior art can only play the role of blocking rain and air. In a humid environment, the corrosion resistance of mechanical equipment cannot be guaranteed. Once these large equipment rust, the value will be greatly reduced, and even affect the quality of the equipment. Normal use

However, in the current packaging materials, there has not been any relevant technical report on compounding the vapor phase antirust agent into the packaging material.
