Problems solved by technology

[0003] Due to the use of adhesives in the production process of traditional wall panels such as medium density fiberboard and multi-layer wood plywood, the adhesive inside the wall panels will volatilize harmful gases, which will cause certain negative effects on human health and the environment.
In addition, traditional wall panels need to consume a lot of log resources, and excessive consumption of log resources will also have an adverse impact on the earth's ecological environment
[0004] In addition, the existing wall panels made of logs have low toughness and poor bending resistance, and cannot be used in applications that require high bending strength

Embodiment 1

[0057] Such as Figures 1 to 5 Shown is an embodiment of a green ecological hemp fiber integrated wall decorative board of the present invention, including a bottom layer 1, an intermediate layer 2 and a surface layer 3 that are laminated and hot-pressed together, and the bottom layer 1 and the surface layer 3 are both Polyester non-woven fabric layer, the middle layer 2 is a hemp fiber felt layer, and the hemp fiber felt layer is made of two or more prefabricated hemp fiber felts 4 and 5 after stacking and preheating Hemp fiber mat layer, and the prefabricated hemp fiber mat is a mixed fiber mat of hemp fiber and polypropylene fiber, and the hemp fiber and polypropylene fiber in the mixed fiber mat are winding fibers.

[0058] As a preferred solution of this embodiment, the meandering fiber is an S-shaped meandering fiber formed by air-laying.

[0059] The above-mentioned green ecological hemp fiber integrated wall decoration board is mainly composed of the surface layer 3, ...

Embodiment 2

[0070] Such as Figures 1 to 5 Shown is the embodiment that adopts the preparation method of a kind of green ecological hemp fiber integrated wall decorative board of embodiment 1, comprises following method step:

[0071] The first step is to make the middle layer 2;

[0072] The second step is to take the polyester non-woven fabric layer as the bottom layer 1 and the surface layer 3;

[0073] The third step, plate making and forming: after the bottom layer 1, the middle layer 2, and the surface layer 3 are superimposed, the mechanical automatic paving method is used to heat and roll on the rolling forming machine, and the above-mentioned green color is obtained after cutting. Ecological hemp fiber integrated wall panels.

[0074] In the above preparation method, the process steps of making the intermediate layer 2 in the first step are:

[0075] Step 1. Fiber pretreatment: loosen polypropylene fibers and hemp fibers by using a bale opener and a coarse opener;

[0076] St...

Embodiment 3

[0091] Such as Figure 4 Shown, as the preparation system that adopts the preparation method of a kind of green ecological hemp fiber integrated wall decorative board of above-mentioned embodiment 2, comprise the production line that is used to prepare hemp fiber felt, the production line of described hemp fiber felt includes according to production process from input to The order of output is arranged in sequence: bale opener → rough opener → dust removal system → high-speed comber → air-laid machine → pre-looming machine → main loom → oven → roll forming machine.

[0092] As a further improvement, a vacuum deodorizer can also be arranged between the main machine and the oven.

Abstract

The invention relates to the technical field of wall decorating plates for buildings and discloses an environment-friendly ecological bast fiber integrated wall decorating plate and a preparation method thereof. The bast fiber integrated wall decorating plate comprises a bottom layer, a middle layer and a surface layer which are sequentially overlapped and hot-pressed together. Both the bottom layer and the surface layer adopt polyester non-woven fabric layers, and the middle layer adopts a bast fiber felt layer. The bast fiber felt layer is formed in the mode that two or more pieces of precast and formed bast fiber felt are overlapped and preheated, the precast and formed bast fiber felt is mixed fiber felt with bast fibers and polypropylene fibers, and the bast fibers and the polypropylene fibers in the mixed fiber felt are both coiled fibers. The preparation method of the integrated wall decorating plate comprises the steps that the middle layer is manufactured; the polyester non-woven fabric layers are taken as the bottom layer and the face layer; and the bottom layer, the middle layer and the face layer are overlapped, heated and subjected to rolling forming, and the bast fiber integrated wall decorating plate is prepared after cutting. The wall decorating plate is environmentally friendly and ecological.

Description

technical field [0001] The invention relates to the technical field of building wall decorative panels, in particular to a green ecological hemp fiber integrated wall decorative panel and a preparation method thereof. Background technique [0002] Wall decorative board is a commonly used building decoration material, typically medium density fiberboard, multi-layer wood plywood and so on. Among them, medium density fiberboard is a kind of man-made board made by mechanically separating and chemically treating wood or plant fibers, adding adhesives and waterproofing agents, etc., and then molding at high temperature and high pressure; and multi-layer plywood is made of three layers. It is a board made of hot-pressed or multi-layer veneers or thin boards. [0003] Due to the use of adhesives in the production process of traditional wall panels such as medium density fiberboard and multi-layer wood plywood, the adhesive inside the wall panels will volatilize harmful gases, whic...
