Embodiment 1

[0026]Example asfigure 1 As shown, it includes an intermediate base layer 1 and a single-sided IXPE radiation cross-linked polyethylene foamed layer 2. A TPU flexible layer 4 is provided between the structural base 3 of the intermediate base layer 1 and the single-sided IXPE radiation cross-linked polyethylene foamed layer 2. This embodiment is mainly used for a two-layer composite pallet, and the structural bases 3 of the two-layer high-strength composite film are opposed to each other, which meets the requirements of adhesive composite. It can also be used for single-layer pallet molding, and the structure base 3 itself also has the characteristics of wear resistance.

Embodiment 2

[0027]Example twofigure 2As shown, it includes a middle base layer 1 and two sides of IXPE radiation cross-linked polyethylene foamed layer 2, which is mainly used for single-layer pallet molding. Both sides of IXPE radiation cross-linked polyethylene foamed layer 2 provide surface protection.

[0028]Specific implementation process and principle description:

[0029]The IXPE radiation cross-linked polyethylene foam layer 2 has a dense foam layer, and the IXPE radiation cross-linked polyethylene foam layer 2 has excellent fracture tensile resistance, corrosion resistance, electrical insulation and other excellent characteristics, which can meet contact protection And external surface protection, prolong the service life of products.

[0030]The structural base 3 in the intermediate base layer 1 serves as a structural support and also has the characteristics of thermo-compression forming and stretching. The TPU flexible layer 4 serves as a buffer support, which can assist the IXPE radiation c...

Abstract

The invention discloses a high-strength composite film and a preparation process thereof, the high-strength composite film comprises an intermediate base layer, at least one side of the intermediate base layer is provided with an IXPE radiation crosslinked polyethylene foaming layer, the IXPE radiation crosslinked polyethylene foaming layer and the intermediate base layer are hot-pressed and compounded to form the high-strength composite film, the intermediate base layer comprises a structural base, a TPU flexible layer is arranged on the composite surface of the structural base and the IXPE radiation crosslinked polyethylene foaming layer, the structural base and the TPU flexible layer are co-extruded to form an intermediate base layer, and during preparation, the intermediate base layeris subjected to co-extrusion film formation and temperature control and then is thermally compounded with the preheated IXPE radiation crosslinked polyethylene foaming layer into a whole. The middle base layer and the IXPE radiation crosslinked polyethylene foaming layer are subjected to thermal compounding molding, and the middle base layer and the TPU flexible layer are subjected to co-extrusionmolding through the structural base, so that the high-strength composite film has layer structure stability, tensile fracture and delamination are effectively prevented during hot-press molding of the tray, and meanwhile, the tray has the characteristics of bearing and buffering, contact surface protection, collision resistance, corrosion resistance and the like.

Description

Technical field[0001]The invention relates to a high-strength composite film and a preparation process thereof, and belongs to the technical field of hot press forming film materials.Background technique[0002]A pallet is a kind of transportation carrier involved in industrial production, used to load products or workpieces for transportation and operation. It generally has multiple loading positions, and the loading positions include protrusions or sink structures. The pallets also include single-layer pallets and stacked pallets. The stacked pallets need to be designed to match, and an intermediate cavity needs to be left during stacking. Therefore, the structural strength of the stacked pallets is relatively high. The traditional use of ABS plastic or PS Plastic is used as the base material of the pallet.[0003]Some special products, such as cosmetics, have special requirements for pallets. Their outer surface is equipped with a fine coating and oxidation-resistant layer, that is, ...
