Abstract

The utility model discloses a car door interior decoration plate glued by adopting a PUR (Polyurethane) hot-melt adhesive, belonging to the technical field of car parts. The car door interior decoration plate structurally comprises an injection molding part, a fusing layer, a surface attaching layer and a bonding layer, wherein the surface of the injection molding part is fixedly connected with the fusing layer; the fusing layer is bonded and compounded with the surface attaching layer through the bonding layer; the surface attaching layer is made of film-coated leather, artificial leather and the like and is comfortable and soft; and the bonding layer adopts the PUR hot-melt adhesive. As he PUR hot-melt adhesive and the bonded surface attaching layer are adopted, the car door interior decoration plate glued by adopting the PUR hot-melt adhesive, disclosed by the utility model, has the advantages of improving comfort level of the surface of the car door interior decoration plate, improving air quality inside the car room and getting rid of problems such as air pollution, being simple and novel in structure, reducing rejection rate of products, increasing qualified rate of products and the like.

Description

A kind of automobile door internal decoration plate that adopts PUR hot melt adhesive bonding

Technical field

The utility model relates to a kind of inner trim panels, specifically a kind of automobile door internal decoration plate that adopts PUR hot melt adhesive bonding.

Background technology

Along with a large amount of of automobile popularize, increasing of the kind of automobile, also more and more high-end to the demand of automobile door internal decoration plate; To improve the comfort level of vehicular drive; The customer is also more and more harsher to car mass, performance demands simultaneously, and the automobile door internal decoration plate injecting products surface of original production has no and attaches layer, and passenger's arm and door internal decoration plate contiguous sense are very stiff; And original production process is carried out compound in the injection surface spraying adhesive; Environment is caused certain pollution, also can have the residual of part smell, the human body in the car is had certain harm at automotive interior.

Summary of the invention

For overcome existing automotive door inner casing stiff with the deficiency that has certain environment pollution etc.; The purpose of the utility model: the automobile door internal decoration plate that is to provide a kind of PUR of employing hot melt adhesive bonding; Improved surperficial comfort level; And can improve the indoor air quality of automobile, stop problems such as aerial contamination.

It is following that the utility model solves the technical scheme that its technical matters adopted:

A kind of automobile door internal decoration plate that adopts PUR hot melt adhesive bonding, its structure comprises: moulding, fused layer, surface attach layer, tack coat constitutes, and wherein captive joint with fused layer in the surface of moulding, and it is compound through the tack coat bonding that fused layer and surface attach layer.

Described surface attaches layer, and it adopts materials such as pad pasting leather, emulational leather, has comfortable, soft effect.

Described tack coat, it adopts the PUR hot melt adhesive, more traditional spraying adhesive; Do not contain solvent and free TDI, environmentally friendly, be applicable to the heat sensitivity material; Have high-intensity adhesive bonding property, specifically be used for assembling processing, like electronics, auto-industry, in the fields such as the automobile that can bond; Like ABS, TUP, metal etc., plain metal, plastics, glass etc. all there is good cohesive force.

The PUR hot melt adhesive that the utility model is selected for use, bonded assembly surface attaches layer, has improved the comfort level on automobile door internal decoration plate surface; And can improve the indoor air quality of automobile, stop problems such as aerial contamination, and novelty simple in structure; Reduce the product reject rate, improved the advantages such as qualification rate of product.

Through adopting above technical scheme, the utlity model has following beneficial effect:

1, the utility model adopts the PUR hot melt adhesive, has ensured the quality of pasting, and has gas purgings such as nontoxic, tasteless, no free state formaldehyde;

2, in the course of processing, guarantee the homogeneity of intermediate adhesion film, can stop the appearance of situation such as no irregular projection that the surface attaches layer, fold;

3, it adopts the simulated leather goods of corium or better performances because the surface attaches layer, has guaranteed the traveling comfort of indoor occupant, has stopped the appearance of passenger's arm and door internal decoration plate contiguous sense ten minutes problem such as stiff.
