Aviation tray and manufacturing method thereof

Abstract

The invention discloses an aviation tray and a manufacturing method thereof. The aviation tray comprises a bearing panel, the main body of the bearing panel is an integrated EPS (expandable polystyrene) plate, the bottom of the EPS plate is provided with nine EPS supporting posts, PET (polyethylene terephthalate) films are stuck on the surfaces of the bearing panel and the EPS supporting posts, a jack is formed between the EPS supporting posts, the surface of the EPS plate is stuck with the PET films through an EVA (acrylate-vinyl acetate) glue layer, and the nine EPS supporting posts are distributed in 3*3 matrix. The manufacturing method comprises the steps of main body formation, film spraying, heating and cutting, vacuum plastic sucking and cooling formation. The PET films are stuck on the EPS plate so that the aviation tray has the advantage of light weight of the EPS plate, overcomes the defects of poor impact resistance and tension resistance of the EPS plate and has good mechanical property of the PET films; and the tray has the advantages of good folding resistance, capability of tolerating most solvents, good high and low temperature resistance, no toxicity, no taste, sanitation and good safety.

Description

technical field [0001] The invention relates to an auxiliary appliance for warehouse, freight and stacking, in particular to an aviation pallet and a manufacturing method thereof. Background technique [0002] Auxiliary devices used in warehouses, freight and stacking in the prior art generally include wooden brackets, metal brackets and plastic brackets. Wooden brackets use wood as the main material, which is prone to moisture, rot and deterioration, or parasites, which does not meet the health and hygiene requirements of modern logistics, and deforestation will destroy the human ecological environment, which is no longer suitable for the requirements of modern society. Metal brackets have high quality, high cost, and are prone to rust, so there are certain limitations in use. At present, plastic trays have been widely used in various aspects. For example, the invention patent of ZL200520029955.6 discloses a plastic tray with round holes. The round-hole plastic tray is ma...

AI Technical Summary

Problems solved by technology

Polyethylene has excellent low temperature resistance, the lowest operating temperature can reach minus 70 to 100 ° C, good chemical stability, excellent electrical insulation performance, and can withstand most acid and alkali erosion. It is insoluble in general solvents at room temperature and has low water absorption. Because it is a linear molecule, it can be slowly dissolved in some organic solvents, and it is very sensitive to environmental stress of chemical and mechanical effects, and has poor heat aging resistance
