Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard, specifically a barrier type corrugated cardboard. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, mainly composed of at least one layer of corrugated core paper and one layer of cardboard. This type of cardboard has high mechanical strength, capable of withstanding impacts and drops during handling. With a focus on sustainable development and green packaging, corrugated cardboard boxes hold an important position in my country's packaging market. Ordinary cardboard cannot provide insulation and has poor barrier properties. Currently, common insulation materials include polyurethane, polystyrene and other plastic products, and vacuum panels. With the rapid development of the logistics and transportation industry and the food delivery industry, the use of paper packaging products and low-cost, easily recyclable insulation materials will become a development trend. Although existing corrugated cardboard has the strength to meet the packaging requirements of food delivery boxes and packaging boxes, it lacks insulation properties and cannot meet the insulation requirements of food delivery boxes and packaging boxes. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a barrier type corrugated cardboard, comprising a corrugated cardboard body and corrugated paper and outer paper constituting the corrugated cardboard body, wherein the outer paper is bonded and fixed to both sides of the corrugated paper, and heat-insulating foil is bonded and fixed to the side walls of both outer paper layers; a rigid reinforcing frame with a frame structure is fitted and bonded and fixed to the corrugated cardboard body, and a wear-resistant layer bonded and fixed to the heat-insulating foil is provided on the outer side of the corrugated cardboard body.

[0005] The present invention is further configured such that the corrugated cardboard body includes a base plate and a side plate fixed to the top of the base plate.

[0006] The present invention is further configured such that the side plates are arranged in a rectangular array of multiple plates, and inclined grooves are provided at both ends of the side plates.

[0007] The present invention is further configured such that two adjacent inclined grooves are bonded and fixed together, and the rigid reinforcing frame at the bottom of the side plate is symmetrically provided with connecting grooves.

[0008] The present invention is further configured such that the top of the rigid reinforcing frame of the base plate is integrally formed with multiple connecting plates in a rectangular array, and the connecting plates are fitted into the connecting groove.

[0009] The present invention is further configured such that a screw hole is provided at the center of the connecting plate, and a fastening bolt is installed on the side wall of the side plate.

[0010] The present invention is further configured such that the fastening bolt passes through the rigid reinforcing frame and is threaded into the screw hole.

[0011] The present invention is further configured such that the wear-resistant layer is made of PVC material, and multiple wear-resistant layers are respectively bonded and fixed to the outer wall of the base plate and the side plate.

[0012] In summary, this utility model has the following beneficial effects: By bonding and fixing heat-insulating tin foil to the side wall of the outer paper and bonding and fixing a wear-resistant layer to the outer wall of the corrugated cardboard body, the heat-insulating tin foil improves the heat-blocking performance of the corrugated cardboard body, and the wear-resistant layer reduces the wear of the outer heat-insulating tin foil, thus improving the heat insulation of the corrugated cardboard; by bonding and fixing a rigid reinforcing frame to the outside of the corrugated cardboard body, and inserting the connecting plate at the top of the bottom plate rigid reinforcing frame into the connecting groove of the side plate rigid reinforcing frame, and simultaneously inserting the fastening bolts through the threaded rigid reinforcing frame into the screw holes of the connecting plate, it is convenient to fix multiple corrugated cardboards (side plates / bottom plates), thus improving the stability of the connection of the corrugated cardboard constituting the box body.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] A type of barrier corrugated cardboard, such as Figure 1-4As shown, the corrugated cardboard body includes a corrugated paper 10 and an outer layer paper 11 constituting the corrugated cardboard body. The outer layer paper 11 is glued and fixed to both sides of the corrugated paper 10. Heat-insulating foil 9 is glued and fixed to the side walls of both outer layers paper 11. A rigid reinforcing frame 2 with a frame structure is glued and fixed on the corrugated main body. A wear-resistant layer 12 is provided on the outer side of the corrugated cardboard body and glued and fixed to the heat-insulating foil 9.

[0017] The corrugated cardboard body includes a base plate 1 and side plates 3 fixed to the top of the base plate 1. Multiple side plates 3 are arranged in a rectangular array, and inclined grooves 4 are opened at both ends of the side plates 3. Adjacent inclined grooves 4 are glued and fixed together. Heat insulation foil 9 is glued and fixed to the side wall of the outer layer paper 11, and wear-resistant layer 12 is glued and fixed to the outer wall of the corrugated cardboard body. The heat insulation foil 9 improves the heat insulation performance of the corrugated cardboard body, and the wear-resistant layer 12 reduces the wear of the outer heat insulation foil 9 and improves the heat insulation of the corrugated cardboard.
