Description

Technical Field

[0001] The utility model relates to an automobile interior trim, in particular to an adhesive board for an automobile main carpet. Background Art

[0002] Carpet glue is used on the back of the carpet due to its good adhesiveness, which can effectively prevent the carpet from sliding, and can also play a buffering role and reduce noise. It is widely used in automobile interior carpets. However, over time, it will age and deteriorate, seriously affecting its service life. Summary of the Invention

[0003] Aiming at the technical problems that the existing carpet glue is prone to aging and deterioration after long-term use, releasing toxic and harmful odors, and affecting the overall performance and service life of the carpet, the utility model provides an adhesive board for an automobile main carpet with anti-aging property, not easy to deteriorate after long-term use, no toxic and harmful odors, and long service life.

[0004] To this end, the technical solution of the utility model is that an adhesive board for an automobile main carpet includes a glue board main body, an adhesive layer and a film. The glue board main body is connected to the film through the adhesive layer. The glue board main body is made of polyester fiber material. The surface of the adhesive layer is coated with solid glue. Raised portions are provided on both side surfaces of the glue board main body. The film is extruded and formed by a single-screw exhaust extruder. The film is composed of a main material and an auxiliary agent in a proportional combination. The main material includes ethylene propylene diene monomer (EPDM) and ethylene-vinyl acetate (EVA) resin. The auxiliary agent includes a filler and a lubricant. The filler is barium sulfate or calcium carbonate, and the lubricant is polyethylene wax.

[0005] Preferably, the solid glue is phenolic resin.

[0006] Preferably, the film contains a flame retardant.

[0007] The beneficial effects of the utility model are as follows:

[0008] (1) Since raised portions are provided on both side surfaces of the glue board main body, the contact area is increased, making the connection more reliable, and the raised portions can play a role in anti-sliding, improving the anti-sliding effect;

[0009] (2) Since the glue board main body is made of polyester fiber material, it has good sound insulation effect and high environmental protection performance, avoiding the generation of peculiar smell and aging during long-term use, and extending the overall service life of the product;

[0010] (3) The film is extruded and formed by a single-screw exhaust extruder, enabling the full discharge of volatile small-molecule materials, further ensuring the low-odor performance of the product and improving the environmental protection effect;

[0011] (4) By adding a flame retardant to the film, the rubber sheet has a certain flame retardant effect, improving the safety of product use. Description of the Drawings

[0016] 1. Rubber sheet main body; 2. Adhesive layer; 3. Film; 4. Protrusion. Detailed Embodiment

[0017] The following further describes the present invention in conjunction with embodiments.

[0018] As Figures 1-3 shown, a rubber sheet for an automotive main carpet includes a rubber sheet main body 1, an adhesive layer 2, and a film 3. The rubber sheet main body 1 is connected to the film 3 through the adhesive layer 2. The rubber sheet main body 1 is made of polyester fiber material. The surface of the adhesive layer 2 is coated with solid adhesive. A plurality of protrusions are provided on both surfaces of the rubber sheet main body 1. The film 3 is extruded and formed by a single-screw exhaust extruder. The film 3 is composed of a main material and an auxiliary agent in a proportional combination. The main material mainly includes ethylene propylene diene monomer (EPDM) and ethylene-vinyl acetate (EVA) resin. The auxiliary agent mainly includes a filler and a lubricant. The filler adopts barium sulfate and calcium carbonate. The lubricant adopts polyethylene wax. The solid adhesive adopts phenolic resin. The main material of the film 3 also contains a flame retardant.

[0019] Since a plurality of protrusions are provided on both surfaces of the rubber sheet main body 1, the contact area is increased, making the connection more reliable, and the protrusion 4 can play an anti-slip role, improving the anti-slip effect; since the rubber sheet main body 1 is made of polyester fiber material, it has good sound insulation effect and high environmental protection performance, avoiding the phenomena of generating peculiar smell and aging during long-term use, and extending the overall service life of the product; the film 3 is extruded and formed by a single-screw exhaust extruder, enabling the full discharge of volatile small molecule materials, further ensuring the low odor performance of the product and improving the environmental protection effect; by adding a flame retardant to the film 3, the rubber sheet has a certain flame retardant effect, improving the use safety of the product.

[0020] However, the above are only specific embodiments of the present utility model, and the scope of implementation of the present utility model cannot be limited thereby. Therefore, the replacement of equivalent components or equivalent changes and modifications made according to the scope of patent protection of the present utility model shall still fall within the scope covered by the claims of the present utility model.
