Description

Multilayer composite sheet structure

This work is about multi-layer panels, especially a multi-layer composite panel structure.

In engineering applications, many boards are often required, such as decorative boards, furniture boards (such as desks, chairs, sofas, cabinets, etc.), floors (wood floors) or system cabinet boards, or PCB (printed circuit board industry). Drill backing plate or top cover. The consumption of these boards is quite large, and they are generally made of wooden boards or plastic boards. The cost of wood and plastic boards is relatively high, and the disposal of waste is also a big problem. For example, thermosetting plastic products, there are almost only two final disposal methods: burial and incineration. The problem of environmental protection, if the method of incineration is adopted, will further promote the deterioration of the global warming effect.

From an environmental engineering perspective, waste is a misplaced resource. If the resources can be recycled and reused in an appropriate way, and then made into usable products, on the one hand, the waste that needs to be treated can be reduced, and the further utilization of the waste can achieve the purpose of reducing the use of natural resources.

Therefore, if a simple process can be applied, and waste materials are used as much as possible to form the above-mentioned building boards, or the drilling pads or upper cover boards of PCB (printed circuit board industry), a new and easy-to-operate The reuse method forms a new type of material, which can obtain various benefits, which is different from the traditional incineration and burial of environmental engineering final treatment methods. In order to widely increase the characteristics of waste fiber recycling, and achieve the goal of circular economy and the concept of environmental sustainability.

Therefore, this case hopes to propose a new one to solve the above-mentioned defects in the prior art.

Therefore, the purpose of this creation is to solve the above-mentioned problems in the conventional technology. In this creation, a multi-layer composite sheet structure is proposed, wherein the glue or hot melt adhesive used in the overall structure does not contain formaldehyde and can be used as a formaldehyde-free sheet, so it is not Harmful to human body. Furthermore, for the above-mentioned production materials, a large number of recycled materials can be used, and the overall cost is relatively low. Moreover, the paper layer, the waste paper layer and the PE film layer can be recycled and reused, so the impact on the environment is low, and the purpose of environmental protection can be achieved. In addition, these are made of fairly lightweight materials, so the overall weight is not large, so it is easy to carry and construct.

In order to achieve the above-mentioned purpose, this creation proposes a multi-layer composite sheet structure, comprising: multi-layer paper layers; multi-layer PE film layers, wherein the multi-layer paper layers and the multi-layer PE film layers are alternately arranged, and the multi-layer PE film layer after hot-melting is applied. Film layer or adhesive bonding; in this case, the multi-layer paper layer and the multi-layer PE film layer are staggered and bonded to form a composite board with a certain thickness; the composite board can be used as a drilling pad for building materials or a printed circuit board industry. cover plate.

The multi-layer composite sheet structure also includes: at least one layer of aluminum foil, which is interleaved with the above-mentioned multi-layer paper layer and the multi-layer PE film layer, and is bonded to other plates by the multi-layer PE film layer or the adhesive after hot-melting ; The aluminum foil board is waterproof and waterproof, so that water or moisture can be isolated.

The multi-layer composite board structure further comprises: at least one layer of waste paper, which is a laminate formed by collecting a large number of waste papers. The waste paper layer is formed by the waste materials of the general Tetra Pak package; the Tetra Pak package is a packaging material composed of a paper layer and a PE film layer. The waste paper layer is interposed between the staggered multi-layer paper layers and the multi-layer PE film layers. Or the waste paper layer is inserted on the outer surface of the multi-layer paper layer and the multi-layer PE film layer which are staggered to improve the aesthetics of the multi-layer composite board.

The features and advantages of this creation can be further understood from the following description, and please refer to the Check the attached drawings.
