Embodiment Construction

[0032] Such as Figure 1 to Figure 6 Shown, be a kind of composite cardboard of the present invention, comprise cardboard layer 1, pearl cotton layer 2 and aluminum foil layer 3, aluminum foil layer 3 is bonded and fixed on the front of pearl cotton layer 2 by adhesive, and this adhesive is mass ratio It is the composition of (3~8):(2~5):1:(0.1~0.3) polyester resin, silicone resin, epoxy resin and curing agent. Aluminum foil layer 3 has the advantages of tasteless, odorless, non-toxic, high temperature resistance, low temperature resistance, good plasticity, strong air barrier performance, anti-oxidation, waterproof, moisture-proof, etc. The surface of aluminum foil is extremely clean and hygienic, and no bacteria or microorganisms can be on its surface growth, play an antibacterial role. The cardboard layer 1 is bonded and fixed on the back of the pearl cotton layer 2. The thickness of the pearl cotton layer 2 is 3-7mm. The thermal conductivity of the pearl cotton is very lo...

Abstract

The invention discloses a composite paperboard and a making method of the composite paperboard. The composite paperboard comprises a paperboard layer, a pearl wool layer and an aluminum foil layer, the aluminum foil layer is bonded and fixed on the front side of the pearl wool layer, the paperboard layer is bonded and fixed on the back side of the pearl wool layer, the making method comprises thefollowing steps: (a) placing the paperboard in position; (b) cutting; (c) blocking pearl wool; (d) applying a glue; (e) thermally pressing in vacuum; and (f) drying. The composite paperboard has the advantages of oxidation resistance, antibacterial action, moisture resistance and strong impact resistance, the storage times of melons and fruits are prolonged when the composite paperboard is used tomake a packaging box for the melons and fruits, the fresh preservation property is strong, the melons and fruits are prevented from being deformed by the external extrusion, the transportation safetyof the melons and fruits is guaranteed, the making method is easy to control, less waste is produced, the time is short, the cost is low, the labor intensity of a worker is low, and the product quality is high.

Description

technical field [0001] The invention belongs to the technical field of cardboard production, in particular to a composite cardboard and a manufacturing method thereof. Background technique [0002] In recent years, with the improvement of people's living standards, the requirements for product packaging are getting higher and higher. As the outer packaging container of melons, fruits and vegetables, cartons can not only ensure the transportation safety of commodities, but also play a role in beautifying commodities, increasing added value and promoting sales. Especially in recent years, various new types of exquisitely printed Moisture-proof and glazing cartons have greatly improved the product quality of packaging cartons, and fundamentally solved the problems that carton packaging is prone to moisture, mildew and damage. In the prior art, during the bonding process of the cardboard, the water-resistant waterproof paint is coated on the surface of the paper by spraying or ...
