Problems solved by technology

Thereby, the plastic plate that is made with plastic as raw material is then more and more adopted by people, and when the plastic plate of prior art is selected as the plate of above-mentioned product for use, a kind of is to adopt injection molding mode to make, but, The quality of the plastic board of this structure is relatively heavy, it is very inconvenient to move, and it requires expensive equipment and molds, especially for large-sized boards, it is not easy to make; the other is made by blister forming. Although composite panels have the characteristics of light weight, easy cleaning, low cost and beautiful appearance, such composite panels usually need to be filled with honeycomb paperboard and inner linings between the panel and the bottom plate to enhance its strength, which brings great difficulties to the production. A certain degree of difficulty, resulting in the production cost can not be reduced, affecting the competitiveness of the product

Embodiment 1

[0049] Embodiment 1, referring to Fig. 1 to Fig. 7, a plastic composite plate with a friction welding structure of the present invention is used on a seat. Fig. 1 shows a schematic structural view of a seat, the seat It includes a chair frame 3, a chair board 1 and a chair back 2 mounted on the chair frame 3, and the chair board 1 and the chair back 2 are plastic composite boards with a friction welding structure.

[0050] As shown in Figures 2 to 5, the chair board 1 includes:

[0051] The plastic panel 11 is a monomer structure with a certain shape made by direct extrusion molding or extrusion molding, and has an upper surface and a lower surface;

[0052] The injection molded part 12 is a single structure made by direct injection molding and matched to the shape of the plastic panel. Its upper part is integrally injection-molded with several upwardly protruding ribs 121. The top of the ribs 121 is connected with the bottom of the plastic panel 11. There are several small p...

Embodiment 2

[0060] Embodiment 2, as shown in FIG. 8, a plastic composite board with a friction welding structure of the present invention is used on a seat. The difference from Embodiment 1 is that the surface of the panel is provided with a printing layer 112, The printing layer 112 is a texture or pattern structure directly printed on the surface of the panel by printing.

Embodiment 3

[0061] Embodiment 3, as shown in Fig. 9 to Fig. 10, a plastic composite plate with a friction welding structure of the present invention is used on a seat. Fig. 9 shows a structural schematic diagram of another structural seat, which The seat comprises a chair frame 30, a chair board 10 and a chair back 20 mounted on the chair frame 30, and the chair board 10 and the chair back 20 are plastic composite plates of friction welding structure.

[0062] Among them, the chair board 10 includes a plastic panel 15, an injection molded part 16 and an embedded reinforcement 17; the plastic panel 15 is a single structure with a certain shape made by direct extrusion molding or extrusion molding. surface and lower surface; the upper part of both sides of the injection molded part 16 is integrally injection-molded with several upwardly protruding ribs 161, and the top of the ribs 161 is provided with small convex lines or small bumps (not shown in the figure), and the plastic panel 15 and ...

Abstract

This invention discloses a friction welding structural plastic composite board, including plastic panels, injection molded parts, plastic panel is formed by extrusion directly or by suck mold after extrusion, injection mold parts can be directly or more than one injection parts composition, injection molded part contacts with plastic panel through friction welding, under the surface of injection parts and plastic panels have a number of contacts for friction welding. In the high structural strength requirements of the situation can still go into some buried enhance pieces between plastic panels and injection parts, to improve strength and reduce the amount of plastic pieces. Using of the structure, the plastic composite boards have low costs, the materials used small, easy processing, light weight, easy production process automation, composite plate surface formation, bright and clean etc. advantages, plates can be used chairs, filing cabinets, lockers, materials planes, decorative wall plates, etc. wardrobe shelves.

Description

technical field [0001] The invention relates to a plastic composite board, in particular to a plastic composite board with a friction welding structure. Background technique [0002] Panel is a material commonly used in the construction industry or furniture manufacturing industry. For example, it can be used as a wall decoration panel, or it can be used to make the panel of the table, the seat and back of the chair, the partition of the bookshelf or the cabinet, the head of the bed or the The bezel at the end of the bed, etc. The earlier wall decoration panels, or the panels of various tables such as conference tables, dining tables, leisure tables, computer tables, etc., or the seat and backrest of chairs, bookshelves or cabinet partitions and other indoor and outdoor products. Most of the boards in my country still use wood boards, fiberboards or particle boards. These wood-based boards will be used less and less with the reduction of forest resources in our country, the ...
