Abstract
The utility model relates to an automobile interior trim roof without a releasing agent, which is formed by adhering upper layer non-woven fabric, upper layer glass fibre, an adhesive polyurethane plate, lower layer glass fibre, lower layer non-woven fabric and shell fabric in sequence. The utility model is characterized in that rubber sheets are added between the upper layer non-woven fabric and the upper layer glass fibre. The automobile interior trim roof is not provided with a releasing agent, and therefore, adhesive stickers and double faced adhesive tapes can be conveniently utilized to adhere roof accessories of spacer blocks, wiring harnesses and the like; the labor intensity and the labor time of production workers are reduced, and the manufacture process is simple and feasible.
Description
Technical field
The utility model relates to a kind of automotive trim top, refers to a kind of not with the automotive trim top of mold release especially.
Background technology
At present, existing automotive trim top by nonwoven fabrics, glass fibre, band glue polyurethane sheet, glass fibre, nonwoven fabrics and lining in order in mould molding bonded form.Glue in the band glue polyurethane sheet can pass glass fibre when the top moulding and nonwoven fabrics leaks on the die face, and the glue that leaks out can cause top to be bonded at mould can't taking out; For guarantee top can be after moulding depanning smoothly, prior art is to prevent that at release agent spraying on the die face top is bonded on the mould, still, because of top contacts with mould, mold release simultaneously can be attached on the top; Because the mold release attached to the top back side exists, cause non-drying glue, double faced adhesive tape can't be bonded in the top back side, must use the hot melt adhesive common annex on the tops such as space block, wire harness that bonds in the production, so increase material input, producers' labour intensity and production time.
Summary of the invention
Because the deficiency of above-mentioned existing automotive trim top, the technical matters that solves is: provide a kind of not with the automotive trim top of mold release, it can use top annexes such as Pressure sensitive adhesive tape, double faced adhesive tape bonding space block, wire harness easily, producers' labour intensity and working time have been reduced, the manufacturing process simple possible.
For solving the problems of the technologies described above, it is a kind of not with the automotive trim top of mold release that the utility model provides, it is bondd in order by upper strata nonwoven fabrics, upper strata glass fibre, band glue polyurethane sheet, lower floor's glass fibre, lower floor's nonwoven fabrics and lining and forms, wherein, in the middle of upper strata nonwoven fabrics and upper strata glass fibre, add film;
Described film has three-decker, and wherein, the fusing point of upper and lower double-layer structure is lower than the fusing point of interlayer structure;
The fusing point of the upper and lower double-layer structure of described film is 120 ℃-130 ℃;
The fusing point of the interlayer structure of described film is higher than 150 ℃;
The upper and lower double-layer structure of described film is made by polyethylene, and the interlayer structure of described film is made by nylon.
Below in conjunction with drawings and Examples the utility model is done detailed description further:
Description of drawings
Fig. 1 is a three-dimensional exploded view of the present utility model; And
Fig. 2 is the partial enlarged drawing of film of the present utility model.
The specific embodiment
Existing automotive trim top is by the upper strata nonwoven fabrics, the upper strata glass fibre, band glue polyurethane sheet, lower floor's glass fibre, lower floor's nonwoven fabrics and lining in order in mould molding bonded form, glue in the band glue polyurethane sheet can pass glass fibre when the top moulding and nonwoven fabrics leaks on the die face, therefore prevent that at release agent spraying on the die face top is bonded on the mould, but mold release simultaneously can be attached on the top, the upper strata nonwoven fabrics of automotive trim top is in order to the bonding space block, common annex on the tops such as wire harness, so should avoid adhering to mold release, the utility model is to add film in the middle of upper strata nonwoven fabrics and upper strata glass fibre, when the utility model during at in-mold molding, utilize film to prevent to pass the upper strata glass fibre and the upper strata nonwoven fabrics leaks on the die face, thereby avoid using mold release with the glue in the glue polyurethane sheet.
As shown in Figure 1, a kind of the bonding in order by upper strata nonwoven fabrics 10, film 20, upper strata glass fibre 30, band glue polyurethane sheet 40, lower floor's glass fibre 50, lower floor's nonwoven fabrics 60 and lining 70 with the automotive trim top of mold release of the present utility model forms; Wherein, as shown in Figure 2, film 20 comprises three-decker 21,22,23, superstructure 21 and understructure 22 are made by polyethylene, and fusing point is identical, be 120 ℃-130 ℃, the interlayer structure 23 of film is made by nylon, and fusing point is higher than the fusing point of upper and lower double-layer structure, and is higher than the heating-up temperature of mould simultaneously, promptly be higher than 150 ℃, the fusing point of the interlayer structure 23 of film is 150 ℃-160 ℃ in this specific embodiment.
When the utility model is heated to about 130 ℃-145 ℃ in mould, on film, following double-layer structure 21,22 fusing point, superstructure 21 is fused into glue can guarantee that film 20 is bonded on the upper strata nonwoven fabrics 10, understructure 22 is fused into glue can firmly cling upper strata glass fibre 30, and the mold heated temperature is lower than the fusing point of the interlayer structure 23 of film 20, so interlayer structure 23 remains solid-state and can effectively prevent and leaks into die face with the glue in the glue polyurethane sheet 40, because of the glue in the band glue polyurethane sheet can't leak into die face, so in the production process without release agent spraying, simultaneously, the utility model does not influence the rigidity of top, main performance index such as hardness.
Claims (5)
