Embodiment Construction
[0007] The raw material components of gas-phase anti-rust cushioning packaging sheet are characterized by mass percentage: polyethylene resin is 70-99%, gas-phase corrosion inhibitor VCI is 0.55-18%, auxiliary agent is 0.05-12%, and the dispersion The additive is 0.5-3%, the auxiliary material is 0-0.5%, and the sum of the mass percentages of the above components is 100%.
[0008] The manufacturing method of the sheet: firstly carry out pretreatment of powder raw materials: mix the selected VCI powder material with dispersant according to the above components, and carry out micronization treatment through a grinder to make the particle size reach more than 600 mesh; Vinyl resin, vapor phase corrosion inhibitor VCI powder and dispersant are mixed evenly, then added to the barrel of polyethylene foam extruder, heated and melted at 140-210°C, mixed with auxiliary materials and auxiliary materials, extruded through polyethylene foam extruder Then, the size of the sheet is fixed by...
