Description

Technical Field

[0001] The utility model relates to the technical field of paperboards, in particular to a coated paperboard with waterproof and sun-proof functions. Background Art

[0002] Cardboard, also known as board paper, is a thick paper sheet made from various pulps and composed of interwoven fibers. The difference between cardboard and paper is usually distinguished by quantity and thickness. According to its use, it can be divided into packaging cardboard, such as boxboard, kraft boxboard, yellow cardboard, white cardboard, impregnated liner cardboard, etc.

[0003] Existing cardboard is usually folded into a packaging box to wrap objects. However, during the transportation of objects, it is very likely that the objects will shake inside the packaging box, thereby squeezing the packaging box, which can easily cause damage to the packaging box, making the overall appearance of the packaging box difficult for users to accept.

[0004] Therefore, it is necessary to provide a coated cardboard with waterproof and sun-proof functions to solve the above technical problems. Utility Model Content

[0005] The purpose of the present invention is to provide a coated cardboard with waterproof and sun-proof functions to solve the problem in the above-mentioned background technology that during the transportation of objects, the objects are likely to shake inside the packaging box, thereby squeezing the packaging box, which can easily cause damage to the packaging box, making the overall appearance of the packaging box difficult for users to accept. The technical solution of the present invention addresses the technical problem that the existing technical solutions are too single and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a coated cardboard with waterproof and sun-proof functions, comprising upper and lower corrugated cardboards, wherein the upper and lower corrugated cardboards are provided with an adhesive layer at opposite ends thereof, a facial paper is provided at opposite ends thereof, a buffer component is provided at the opposite end thereof, a waterproof inner membrane is provided at the separated end of the corrugated cardboard, a waterproof coating is provided at the separated end thereof, and a film layer is provided at the separated end of the waterproof coating.

[0007] Preferably, the buffer assembly includes connecting plates arranged on the upper and lower central surfaces of the facial paper, buffer arc plates are equidistantly arranged at the upper and lower ends of the connecting plate, and semicircular plates are connected to both ends of the connecting plate.

[0008] Preferably, the buffer arc plate is made of rubber.

[0009] Preferably, the waterproof coating is made of vinyl chloride.

[0010] Preferably, the waterproof inner membrane is made of polyethylene.

[0011] Preferably, the film layer is made of polyester fiber.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model provides a buffer arc plate. When the cardboard is hit or squeezed by an object, the buffer arc plate deforms to absorb the impact and squeezing force, thereby reducing the squeezing force on the cardboard body and reducing the possibility of damage. The buffer arc plate is made of rubber and has good buffering performance.

[0014] The utility model can reduce the wear on the surface of the waterproof inner membrane by setting a waterproof coating. The waterproof inner membrane adopts polyethylene with excellent chemical stability and corrosion resistance, and the thin film layer adopts polyester fiber with good sun protection function.
