Description

Technical Field

[0001] The utility model relates to the technical field of a vehicle sunshade curtain with a hot-melt adhesive layer, in particular to a vehicle sunshade curtain with a hot-melt adhesive layer. Background Art

[0002] At present, cars use glass as the roof to form the car's sunroof structure, but compared with the traditional roof, the sunshade and heat insulation effects are relatively poor. The existing car sunroof sunshade needs to be installed on the inner side of the roof through a bracket, which takes up more space and is relatively cumbersome to install. There is also an electrostatic adsorption sunshade, which is installed by electrostatic adsorption on the glass. However, since the sunshade is heavier than the traditional electrostatic sticker, the adsorption force of electrostatic adsorption is limited, and it is easily affected by humidity, temperature and dust on the glass surface, resulting in insufficient adsorption. Therefore, improvement is needed. Summary of the invention

[0003] The purpose of the utility model is to provide a car sunshade with a hot melt adhesive layer. The sunshade is integrally bonded to the inner side of the roof glass through the bottom hot melt adhesive layer. The bonding method is better than electrostatic adsorption, and the firmness is better. Compared with the traditional sunshade installed by the bracket, it is easy to disassemble and save the space in the car. In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0004] A vehicle sunshade with a hot melt adhesive layer comprises a curtain fabric layer and a sound insulation and heat insulation layer arranged on the back of the curtain fabric layer, wherein the back of the sound insulation and heat insulation layer is provided with a hot melt adhesive layer, and the hot melt adhesive layer covers the entire area of ​​the sound insulation and heat insulation layer.

[0005] Furthermore, the sound insulation and heat insulation layer is a sponge layer.

[0006] Furthermore, the surface of the hot melt adhesive layer away from the sound insulation and heat insulation layer is covered with release paper.

[0007] Furthermore, a partition layer is provided between the hot melt adhesive layer and the sound insulation and heat insulation layer.

[0008] Furthermore, the interlayer fabric interlayer is a Lycra fabric layer.

[0009] Furthermore, the fabric interlayer is a Lycra fabric layer.

[0010] By adopting the above scheme, the sunshade curtain is bonded to the car sunroof glass over a large area through a hot-melt adhesive layer. Compared with electrostatic adsorption, the bonding firmness is good. In addition, the specific disassembly and assembly method of the sunshade curtain is to tear it off or stick it on as a whole, and it can be repeatedly bonded. Compared with traditional sunshades installed by brackets, it is easy to disassemble and assemble, and saves space in the car. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a cross-sectional schematic diagram of the sunshade curtain of the utility model. DETAILED DESCRIPTION

[0012] The present invention is described below in conjunction with the accompanying drawings and specific embodiments.

[0013] like Figure 1 As shown, a car sunshade with a hot melt adhesive layer comprises a curtain layer 1 and a sound insulation and heat insulation layer arranged on the back of the curtain layer 1, wherein the sound insulation and heat insulation layer is a sponge layer 2. A hot melt adhesive layer 3 is arranged on the back of the sound insulation and heat insulation layer, and the hot melt adhesive layer 3 covers the entire area of ​​the sound insulation and heat insulation layer, which can increase the bonding area and improve the bonding reliability. The surface of the hot melt adhesive layer 3 away from the sound insulation and heat insulation layer is covered with a release paper 4 for protection. After the release paper 4 is torn off, the sunshade can be bonded to the sunroof glass.

[0014] Preferably, a partition is provided between the hot melt adhesive layer 3 and the sound insulation and heat insulation layer. The partition is a fabric partition, specifically a lycra fabric layer (omitted in the figure). This can prevent the hot melt adhesive layer 3 from directly bonding with the uneven surface of the sponge layer 2, thereby affecting the bonding effect between them. The layers of the sunshade are bonded together by adhesive.

[0015] The specific composition of the hot melt adhesive layer 3 is as follows:

[0016] Diphenylmethane diisocyanate 9%-11%, butanediol 8%-13%, and the remaining percentage is adipic acid.

[0017] By adopting the above scheme, the sunshade curtain is bonded to the car sunroof glass over a large area through the hot melt adhesive layer 3. Compared with electrostatic adsorption, the bonding firmness is good. In addition, the specific disassembly and assembly method of the sunshade curtain is to tear it off or stick it on as a whole, and it can be repeatedly bonded. Compared with the traditional sunshade curtain installed by the bracket, it is easy to disassemble and assemble, and saves space in the car.
