Problems solved by technology

However, the above two anti-rust packaging materials still have some defects in the practical performance of packaging. For example, the vapor phase anti-rust paper has no cushioning and heat sealing properties, and has limitations in the protection of the smooth surface of metal and metal products and the airtightness of the packaging. ; while the vapor phase antirust plastic film has heat sealing and recyclability, which can provide good packaging airtightn

Example Embodiment

[0007] The manufacturing method of the vapor phase anti-corrosion buffer packaging sheet is characterized in that: the raw material components are calculated by mass percentage, the polyethylene matrix resin is 70 to 99%, the vapor corrosion inhibitor VCI is 0.55 to 18%, and the auxiliary agent is 0.05 to 12. %, 0.5-3% of dispersant, 0-0.5% of auxiliary materials;

[0008] First, the powder raw material pretreatment: mix the selected VCI powder material with the dispersant, and then micronize it with a grinder to make the particle size above 600 mesh; mix the polyethylene resin and the gas phase corrosion inhibitor VCI powder evenly Then add it to the barrel of the polyethylene foaming extruder, heat and melt at 140-210℃, mix with 0.55-12% of additives and 0.5% of auxiliary materials, extrude it through the polyethylene foaming extruder, and place it on the die and die lip. Partially foam, and then fix the size of the sheet by a shaping ring, and finally take up the vapor phase an...

Abstract

The antirust buffering packing sheet is prepared with polyethylene resin 70-99 wt%, gaseous corrosion inhibitor VCI 0.55-18 wt%, assistant 0.05-12 wt% and supplementary material 0-0.5 wt%. The antirust buffering packing sheet has thickness 0.5-15 mm, pores of opened or closed structure and size 0.025-0.5 mm, and foaming rate of 10-50 %. The making process includes compounding material based on the ratio, p-treatment to form fine powder, extruding in extruder and foaming. The sheet has the comprehensive effects of preventing rust, buffering, preventing shock, preventing humidity, etc., may be reused and has wide application and low cost.

Description

technical field [0001] The invention relates to a rust-proof, shock-proof, cushioning and smooth surface protection packaging material for metal products and a manufacturing method thereof. Background technique [0002] Metal and metal products are easily corroded by air pollution and other environmental pollution during the months to one or two years of transportation, handling, and storage after they are manufactured and before use. The existing packaging materials mainly focus on anti-corrosion issues . However, there are no practical and effective packaging products for anti-scratch and anti-collision, especially for the protection of precision metal parts with high-gloss surfaces. Traditional antirust packaging materials include vapor phase antirust paper, and in recent years, vapor phase antirust plastic films. However, the above two anti-rust packaging materials still have some defects in the practical performance of packaging. For example, the vapor phase anti-rust...
