Abstract

The utility model discloses an automobile EPO luggage case cover plate, which comprises an EPO base material formed by injection molding; further comprising a surface layer disposed on the EPO substrate; under guaranteeing the sufficient intensity of suitcase apron, not only promote the weatherability of suitcase apron under various environment, alleviate the weight of suitcase apron moreover greatly, the production of VOC, smell etc. that significantly reduces simultaneously, in addition, still reaches the purpose of practicing thrift raw and other materials cost. Compared with the base material weight of the traditional PP plastic honeycomb board, which is about 2230g, the base material weight of the product is 386g and 1844g of the base material weight of the whole product is reduced after the EPO material is adopted.

Description

Automobile EPO luggage case cover plate

Technical Field

The utility model relates to an auto-parts field, concretely relates to car EPO suitcase apron.

Background

The trunk cover plate is a cover plate in the automobile trunk and is usually arranged on the spare tire, the trunk cover plate cannot have abnormal sound and can be taken down or turned over, the spare tire and tools can be conveniently taken out, the trunk cover plate plays a role in decoration and bearing, and related articles are placed on the trunk cover plate. The existing luggage case cover plate is generally formed by sequentially connecting PP, glass fiber, paper honeycomb, PP, glass fiber, non-woven fabric or non-woven fabric, glass fiber, PU, paper honeycomb, PU, glass fiber and non-woven fabric by using a binder, and the spare tire cover plate has the following defects: after being pressed by a heavy object, the paper honeycomb is easy to deform, has insufficient strength and short service life; the paint has poor weather resistance, is easy to embrittle in a low-temperature environment, and is easy to age under the long-term action of high temperature and ultraviolet rays; the VOC content is high, and the environment is not environment-friendly enough; the product is heavy and not light enough; can not be recycled, and causes resource waste.

Therefore, in order to solve the above problems, a novel trunk lid plate for an automobile is needed, which can solve the weather resistance problem of the trunk lid plate made of the traditional PP honeycomb plate, improve the weather resistance of the trunk lid plate under various environments, and further reduce the weight and cost of the trunk lid plate relative to the PP plastic trunk lid plate.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a car EPO luggage trunk lid is guaranteeing under the sufficient intensity of luggage trunk lid, not only promotes the weather resistance ability of luggage trunk lid under various environment, alleviates the weight of luggage trunk lid moreover greatly, and the production of VOC, smell etc. that significantly reduces simultaneously still reaches the purpose of practicing thrift raw and other material cost.

The utility model discloses an automobile EPO luggage case cover plate, which comprises an EPO base material formed by injection molding;

further, the EPO membrane comprises a surface layer arranged on the EPO base material;

further, the surface layer and the EPO base material are subjected to hot-pressing composite molding;

further, the surface layer is made of PET material;

furthermore, the surface layer is two layers respectively compounded on the upper surface and the lower surface of the EPO base material;

further, the thickness of the single-layer surface layer is 1.5-3 mm.

The utility model has the advantages that: the utility model discloses a car EPO luggage case apron, under guaranteeing the sufficient intensity of luggage case apron, not only promote the weather resistance of luggage case apron under various environment, alleviate the weight of luggage case apron greatly moreover, the production of VOC, smell etc. that significantly reduces simultaneously, in addition, still reach the purpose of practicing thrift raw and other materials cost. Compared with the base material weight of the traditional PP plastic honeycomb board, which is about 2230g, the base material weight of the product is 386g and 1844g of the base material weight of the whole product is reduced after the EPO material is adopted.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a schematic structural view of the present invention;

fig. 2 is a cross-sectional view of the present invention.

Detailed Description

Fig. 1 is a schematic structural diagram of the present invention, fig. 2 is a cross-sectional view of the present invention, and as shown in the drawings, the automobile EPO luggage compartment cover plate in the present embodiment includes an injection molded EPO base material 1; the substrate of suitcase apron passes through EPO material injection moulding, specifically is for putting into the mould with the EPO particle, lets in high temperature high pressure steam chamber and carries out steam heating, makes the raw materials thermally equivalent inflation, and after the primary forming, the mould heats corresponding temperature, and extrusion die makes the product surface melt plastify under high temperature high pressure simultaneously, lets in cooling water cooling product, just makes fashioned EPO substrate 1 after the drawing of patterns. EPO is a foaming copolymer of foaming polyethylene and styrene polymer, and has excellent shock resistance and energy absorption, good weather resistance, chemical resistance, oil resistance, environmental protection and heat insulation.

In this embodiment, the EPO-containing substrate further includes a surface layer 2 disposed on the EPO substrate 1; the surface layer 2 and the EPO base material 1 are fixedly non-glued to replace the coating of the traditional glue, and the formed luggage case cover plate is integrally formed by the EPO base material 1 and the surface layer 2, so that the generation of VOC, smell and the like is greatly reduced.

In this embodiment, the surface layer 2 and the EPO base material 1 are formed by hot-pressing and compounding; after the formed EPO base material 1 is baked, the surface layer 2 is compounded on the EPO base material 1 in a hot-pressing compounding mode, so that the generation of VOC, smell and the like is greatly reduced. And the surface layer subjected to hot-pressing compounding has better coating performance on the EPO base material 1, improves the interlayer structural strength of the trunk cover plate, and avoids the problems of interlayer falling and deformation of the trunk cover plate under heavy pressure.

In the present embodiment, the surface layer 2 is a PET material; the PET is polyethylene terephthalate, has good mechanical property, the impact strength of the PET is 3-5 times that of other films, and the folding resistance is good; oil resistance, fat resistance, olefine acid resistance, dilute alkali resistance and most solvent resistance; the product can be used for a long time within the temperature range of 55-60 ℃, can resist high temperature of 65 ℃ and low temperature of-70 ℃ in short-term use, and has little influence on the mechanical properties of the product at high and low temperatures; the gas and water vapor permeability is low, and the gas, water, oil and peculiar smell barrier performance is excellent; high transparency, blocking ultraviolet ray and high lustrousness.

In this embodiment, the surface layer 2 is two layers respectively compounded on the upper and lower surfaces of the EPO base material 1. That is, the EPO base material 1 was double-sided hot-press molded using a PET material.

In this embodiment, the thickness of the single surface layer 2 is 1.5 to 3 mm.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
