Technical Field

The utility model relates to an automotive interior accessory, in particular to automotive interior leather.

Background

With the rapid development of household automobiles, automobile users have higher and higher requirements for details of various articles in the automobile, and simultaneously, with the rapid development of automobile industry in China, the demand of automobile interior leather is increased year by year.

Chinese patent No. CN201863455U discloses a waterproof automobile interior leather, which comprises a base material, a polyurethane foam layer, an emulsion solidified layer and a polyurethane pattern layer. The polyurethane foaming layer is arranged on the base material, the emulsion curing layer is arranged on the polyurethane foaming layer, and the polyurethane pattern layer is arranged on the emulsion curing layer. The waterproof automobile interior leather has the characteristics of simple and convenient production, attractive appearance and good waterproof performance. However, when the automobile interior leather is produced, the emulsion curing layer and the polyurethane foaming layer need to be manually and completely adhered correspondingly, so that the requirement on operators is high, and the automobile interior leather is inconvenient.

At present, TPO and electronic cross-linked polyethylene are basically adhered to prepare the automotive interior leather on the market, the automotive interior leather is not very good in heat insulation, heat insulation and wear resistance, and the automotive interior leather is easy to damage when being used as an outdoor vehicle.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a convenient bonding car interior trim leather.

The utility model aims at realizing through the following technical scheme: the utility model provides an automobile interior leather, includes foaming board basic unit, bond line, TPU layer and polyurethane decorative pattern layer, the bond line sets up on foaming board basic unit, the TPU layer passes through the bond line and bonds with foaming board basic unit, polyurethane decorative pattern layer sets up on the TPU layer, one side that foaming board basic unit is close to the bond line is provided with the lug, the lug that the TPU layer corresponds foaming board basic unit is provided with relative recess with it.

After the technical scheme is adopted, the foaming board base layer is coated or covered with the bonding layer, then the TPU layer is covered on the bonding layer, the bonding layer is waited to bond the foaming board base layer and the TPU layer together, and the bonding strength is increased along with the prolonging of time. And then coating the polyurethane pattern layer on the TPU layer, and carrying out negative pressure embossing molding. When an operator needs to cover and overlap the TPU layer and the foaming board base layer correspondingly, the groove in the TPU layer is correspondingly matched with the lug on the foaming board base layer, so that the TPU layer and the foaming board base layer can be completely overlapped and covered, the operation requirement on the operator is reduced, and the product quality is improved.

The utility model discloses further set up to: the adhesive layer is a liquid adhesive layer.

After adopting above-mentioned technical scheme, through the setting of liquid adhesive layer for operating personnel can scribble on the foaming board basic unit when being in the liquid state with the adhesive layer. The liquid adhesive layer is arranged, so that the shape of the adhesive layer is not fixed, and the adhesive layer can be matched with the convex blocks on the surface of the foam board when being coated on the foam board base layer, so that the adhesive layer film is formed and completely covers the foam board base layer.

The utility model discloses further set up to: the bonding layer is a glue layer, the glue layer is made of PUR or environment-friendly water-based glue, and the foaming board base layer (1) is electronic cross-linked polypropylene.

By adopting the technical scheme, the viscosity and the fluidity of the glue are good, the glue can be cured within a short time, the bonding effect is rapidly enhanced, and the PUR (reinforced polyurethane) or the environment-friendly water-based glue can not be melted due to too low melting point in secondary processing; the bonding of the electronic crosslinked polypropylene and the TPU effectively replaces the bonding of TPO and electronic crosslinked polyethylene materials used in the current market, so that the automobile interior leather has better heat insulation effect, higher high temperature resistance and stronger wear resistance, and can not be easily scratched.

The utility model discloses further set up to: the convex block and the groove are both arc-shaped.

After the technical scheme is adopted, the convex blocks and the grooves are both arranged to be arc-shaped, so that the bonding layer liquid is not easy to enter dead angles when the bonding layer is coated on the convex blocks, and the bonding effect is optimal. Meanwhile, the circular arc-shaped arrangement improves the contact surface area between the convex block and the groove, and the circular contact area is the largest under the same condition, so that the bonding area is increased, and the bonding effect is improved. In addition, the convex arc-shaped arrangement enables the coordination difficulty between the convex block and the groove to be lower, the convex block is not easy to block, the operation difficulty of operators is reduced, the operation speed of the operators is increased, and the bonding between the foaming board base layer and the TPU layer can be realized before the bonding layer is solidified.

To sum up, the utility model discloses following beneficial effect has:

1. the foaming board base layer and the TPU layer can be completely coordinated without being aligned through the matching of the convex blocks and the grooves on the foaming board base layer and the TPU layer, so that the operation difficulty of an operator is reduced;

2. the convex blocks and the grooves are arranged to be arc-shaped, so that on one hand, the contact area is increased, the bonding area is increased, and the bonding effect is better; on one hand, the adhesive layer can be prevented from flowing into dead corners, the waste of adhesive layer liquid is reduced, and the adhesive effect is improved; on the other hand, the circular arc arrangement reduces the coordination difficulty between the foaming board base layer and the TPU layer, so that the coordination effect of the foaming board base layer and the TPU layer is better;

3. through the setting of liquid bond line, only need scribble the liquid bond line on foaming board base course, need not correspond the coordination with foaming board base course the same with general solid bonding layer, reduced the operation degree of difficulty and operating procedure, it is comparatively convenient, and life is longer, is difficult to damaged.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

As shown in fig. 1 and 2, an automobile interior leather comprises a foam board base layer 1. The foaming board base layer 1 is provided with an adhesive layer 2. The bonding layer 2 is a glue layer, the glue layer is made of PUR or environment-friendly water-based glue, and the foam board base layer (1) is electronic cross-linked polypropylene. The viscosity and the fluidity of the glue are good, the glue can be solidified in a short time, so that the bonding effect is rapidly enhanced, and the PUR (reinforced polyurethane) or the environment-friendly water-based glue can not be melted due to too low melting point in secondary processing; the TPU and the electronic crosslinking polypropylene are bonded to effectively replace TPO and electronic crosslinking polyethylene materials used in the current market, so that the automobile interior leather has better heat insulation effect, higher high temperature resistance and stronger wear resistance, and cannot be easily scratched.
