Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a paste formula EVA board for car, includes composite sheet subassembly, pastes subassembly and test assembly, and composite sheet subassembly includes

EVA board

1, and 1 one end fixed mounting PVC board 7 of EVA board, test assembly include

plastic slab

5, and 5 one ends of plastic slab are fixed and are pasted double faced adhesive tape 6, and the one end that plastic slab 5 was kept away from to double faced adhesive tape 6 is pasted EVA board 1 and is kept away from the one end of PVC board 7, and the one end that EVA board 1 was kept away from to plastic slab 5 is pasted through glue and is had silica gel layer 4.

In the embodiment, before use, the double faced adhesive tape 6 is torn off, the EVA board 1 is adhered to the plastic board 5, the silica gel layer 4 is inserted into the automobile process hole, the silica gel layer 4 perfectly fills the process hole, the silica gel layer 4 is further pulled out, the silica gel layer 4 is cut at the outer end of the automobile process hole to leave the mark of the process hole, the mark left by the process hole is cut, the EVA board 1 perfectly matches the automobile process hole, the adhesion attractiveness of the EVA board 1 is improved, as the EVA board 1 is adhered to the automobile process hole in the adhering process, force cannot be applied to the EVA board 1, the EVA board cannot be accurately adhered to the automobile process hole, when in use, an operator places fingers on the groove 8 to press the EVA board, the EVA board 1 is further adhered to the automobile process hole, after cutting is finished, the double faced adhesive tape 6 is torn off, the plastic board 5 is separated from the EVA board 1, and then tear the cystosepiment 3, insert the industrial compound glue film 2 in the fabrication hole, the industrial compound glue film 2 is pasted on the inner wall of the fabrication hole, play the purpose of plugging the car fabrication hole, because the EVA 1 shape is the same with the fabrication hole, and then the fabrication hole after pasting does not have the stick foot and shrink phenomenon, meet the demand of the product to the aesthetic measure at the same time, through pasting cystosepiment 3 on one section of the industrial compound glue film 2, prevent the external dust or long-term oxidation, make the industrial compound glue film 2 lose efficacy, play the effect of protecting the industrial compound glue film 2, because the cystosepiment 3 pore is bigger, will have water to enter the industrial compound glue film 2 through the cystosepiment 3, and then destroy the use effect of the industrial compound glue film 2, through pasting the waterproof cloth on one end of the cystosepiment 3, make the cystosepiment 3 have the waterproof property, avoid, further destroy the phenomenon of the industrial composite adhesive layer 2, the automobile can generate vibration in the using process, the industrial composite adhesive layer 2 can lose viscosity due to long-term vibration and then fall off from the technical hole, the strength of the EVA plate 1 is increased by arranging the EVA plate 1 into a composite structure, the anti-seismic strength of the EVA plate 1 is increased, the PVC plate 7 is arranged between the EVA plates 1, the plasticizer for increasing the elasticity of the PVC plate 7 is added into the PVC plate 7, so that the elasticity of the PVC plate 7 is higher than that of the EVA plate 1, when the automobile vibrates, the PVC plate 7 disperses the vibration of the EVA plate 1 and further disperses the vibration of the industrial composite adhesive layer 2, so that the viscosity of the reworked composite adhesive layer is more durable, the service life of the EVA plate 1 is longer, the industrial composite adhesive layer 2 is easy to lose viscosity due to the self property, the heat insulation film is adhered on the EVA plate 1, and has better heat insulation effect due to the adhesion of the heat, the adhesive property of the industrial composite adhesive layer 2 can be prevented from losing due to heating.

Furthermore, paste the subassembly and include industry compound glue film 2, industry compound glue film 2 has been laid to the one end that plastic slab 5 was kept away from to EVA board 1, and industry compound glue film 2 keeps away from the one end of EVA board 1 and pastes and has the cystosepiment 3.

In the embodiment, the foam plate 3 is adhered to one section of the industrial composite adhesive layer 2, so that external dust or long-term oxidation is prevented, the industrial composite adhesive layer 2 is made to lose effectiveness, and the effect of protecting the industrial composite adhesive layer 2 is achieved.

Furthermore, waterproof cloth is adhered to one end, far away from the industrial composite adhesive layer 2, of the foam board 3 through glue.

In this embodiment, because the 3 holes of cystosepiment are great, can have water to enter into industry compound glue film 2 through cystosepiment 3, and then destroy the result of use of industry compound glue film 2, through pasting the tarpaulin in 3 one ends of cystosepiment, make cystosepiment 3 have waterproof nature, avoid water to enter into industry compound glue film 2 through cystosepiment 3, and then destroy the phenomenon of industry compound glue film 2.

Furthermore, a heat insulation film is adhered to one end, far away from the PVC plate, of the EVA plate through glue.

In this embodiment, the industrial composite adhesive layer 2 is heated to lose viscosity due to the nature of itself, and the heat insulation film is pasted on the EVA plate 1 and has a better heat insulation effect, so that the industrial composite adhesive layer 2 can be prevented from being heated to lose viscosity.

Further, EVA board 1 is equipped with two, and PVC board 7 is located between two EVA boards 1.

In this embodiment, the car can produce vibrations in the use, and long-term vibrations can make industry compound glue film 2 lose viscidity, and then drops from the fabrication hole, sets up to composite construction through EVA board 1, makes EVA board 1's intensity rise, has increased EVA board 1's shock strength.

Furthermore, the EVA board 1 is symmetrically provided with grooves 8 along the central line.

In this embodiment, because at the in-process of pasting, EVA board 1 and the laminating of car fabrication hole for can't apply force on EVA board 1, make EVA board 1 can't laminate with car fabrication hole accurately, during the use, the operator finger is placed in recess 8, presses EVA board 1, and then with the better laminating of EVA board 1 on car fabrication hole.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
