Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior member for a vehicle, and more particularly to an interior member for a vehicle provided on a vehicle interior side such as a front pillar or a roof side rail of an automobile.

[0002]

2. Description of the Related Art As shown in FIG. 12, a vehicle interior member of this type includes a front pillar garnish 3F provided on a vehicle interior side of a vehicle panel such as a front pillar 2F and a roof side rail 2S of an automobile A, for example. The roof side rail garnish 3S and the like can be cited, and these vehicle interior members keep the aesthetic appearance of the vehicle interior and plastically deform a part of the occupant's body, particularly, a portion directly hit by the head, for example, at the time of a vehicle collision. Thus, the occupant is configured to absorb and reduce the impact force received from the vehicle body.

In recent years, there has been an increasing demand for pile-like patterns in vehicle interior members such as the front pillar garnish 3F due to the desire for a sense of luxury in the room. The interior member for vehicles on which such a pile-like pattern is decorated is made of, for example, a fiber such as rayon having a thickness of about 3 deniers.
It can be obtained by preparing a pile cut into a short fiber having a length of about 0.5 mm, kneading the pile into a resin material, and molding.

[0004]

By the way, the vehicle interior member is exposed directly to ultraviolet rays or visible light from the outside of the vehicle, such as sunlight, so that, for example, ABS resin (a kind of rubber-reinforced styrene resin) is used. When molded with acrylonitrile-butadiene-styrene resin), the butadiene rubber in the resin may be deteriorated, easily cracked, or discolored. The resin used for molding must have a light resistance improver such as an ultraviolet absorber in advance, because it may cause a reduction in the shock absorption performance due to impact, for example, the absorption performance of kinetic energy at the time of occupant collision due to rib deformation of the pillar garnish. And at the same time, adding about 1 part by weight of a pigment to 100 parts by weight of the resin to enhance the concealing property of the resin and secure the light resistance. Attempts have been made.

Therefore, in a vehicle interior member formed by kneading the above-mentioned pile into such a resin material, the fibers (pile) are concealed by the pigment, resulting in a poor pile feeling. Had the problem of becoming

Further, if fibers such as piles are added to the resin material used for molding, the rigidity of the molded interior member for a vehicle is excessively increased and the tensile elongation is significantly reduced. The surface of the pillar garnish is easily cracked, and the head directly collides with the body plate under the pillar garnish, and the impact acceleration generated in the head increases. For example, the head specified in US Standard FMVSS-201 There was also a new problem that the disability index increased and became unsatisfactory under the regulations.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an interior member for a vehicle which can obtain a sharp pattern on the surface while maintaining high shock absorbing performance.

[0008]

Here, it is preferable that the predetermined pattern applied to the acrylic film is a pile-like or non-woven-like pattern.

Further, when the acrylic film contains an ultraviolet absorbent, the resin located on the back side of the film can be effectively prevented from being deteriorated or discolored by ultraviolet light or visible light.

Further, when the acrylic film contains a matting agent, it is possible to avoid a situation in which sunlight or lamps or the like are reflected and hinder driving.

In the case where the acrylic film is composed of a base layer made of an acrylic resin containing an ultraviolet absorbent and a printed layer having a pile-like or nonwoven-like pattern printed on the back surface thereof, The material layer absorbs harmful ultraviolet rays that cause deterioration of the resin, simultaneously protects the ink of the printing layer on the back side, and improves the light resistance and the abrasion resistance of the pattern.

The thickness of the base layer is preferably 50 to 150 μm.

Further, when an acrylic film is welded to the above-mentioned surface side by utilizing resin heat at the time of injection molding, the both are more closely adhered to each other, and the durability is improved.

Here, on the welding surface of the acrylic film,
In the case where the adhesive layer is provided in advance, the bonding strength is increased and the durability is further improved.

The flexural modulus is ASTM D-7.
When the pressure is from 800 to 1900 MPa based on the 90 standard, high impact absorption performance is maintained.

The vehicle interior member of the present invention is suitably used as a pillar garnish, a roof side rail garnish, a door waist garnish, a switch panel, or a cluster panel of an automobile.

[0019]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 1 to 8 show an example in which a front pillar garnish 3F is constructed as a typical embodiment of a vehicle interior member 1 according to the present invention, wherein reference numeral 4 denotes an acrylic film, 5 denotes a skin portion, 6 Indicates a rib portion, respectively. In addition, the shape of the skin portion and the rib portion of the pillar garnish is not limited to the present embodiment at all, and the same shape as the conventional pillar garnish can be adopted.

The front pillar garnish 3F is shown in FIG.
As shown in the figure, a space 30 for absorbing an impact is provided with respect to an inner panel 20 constituting a front pillar 2F on the vehicle body side.
A substantially C-shaped skin portion 5 in cross section, which is covered via
The side wall 5 of the skin portion 5 protrudes into the space 30 from the back surface side of the skin portion 5 facing the inner panel 20 and crosses the longitudinal direction of the inner panel 20.
1 and 52, and one or more thermoplastic resins selected from rubber-reinforced styrene resin, polypropylene resin, polycarbonate resin, polyamide resin, and polyester resin. Injection molding.

On the surface side of the skin portion 5 facing the vehicle interior space,
As can be seen from FIGS. 3 to 8, an acrylic film 4 having a predetermined pattern is provided.

The interior member 1 for a vehicle of the present invention is formed by kneading a pile into a molding resin material by providing such an acrylic film 4 on the surface side facing the interior space of the vehicle. Compared with the pattern, a sharper pattern is formed on the surface, the decorativeness is improved, the increase in rigidity and the decrease in tensile elongation are avoided, and the original high shock absorbing performance of the vehicle interior member can be maintained. is there.

If the acrylic film 4 contains an ultraviolet absorber, the physical property deterioration and discoloration of the skin substrate layer 50 located on the back side of the film due to ultraviolet light or visible light are effectively prevented. The need for the resin material for forming the skin base material layer 50 to contain an ultraviolet absorber or a pigment in advance is reduced, the material cost is reduced, and the shock absorption by the skin base material layer 50 is reduced. Improved performance,
The range of choice of materials is also widened.

The predetermined pattern applied to the acrylic film is preferably a pile or non-woven pattern.

Hereinafter, the configuration of each section will be described in more detail.

As shown in the rear view of FIG. 4, the front pillar garnish 3F of the present embodiment has a plurality of plate-shaped ribs 60,... And each plate-like rib 60
Has a shape of a protruding end edge substantially along the inner panel 20, and a protruding end surface 2 of the inner panel 20.
A main notch 61 opened at a position facing a two-side contact side between the vehicle 1 and the occupant-facing side surface 22, and a position facing a two-side contact side of the protruding end surface 21 and the side surface 23 that is continuous to the other side. And an open auxiliary notch 62.

When such a plate-like rib 60 receives an impact from an occupant, buckling deformation is induced at an intermediate position of projection along an imaginary line connecting the bottoms of the notches 61 and 62, and These bottoms can serve as starting points for cracks directed toward the skin 5. The generation and progress of the buckling and cracking of the plate-like ribs 60 contribute to a more efficient shock absorbing effect. For example, a stepped portion may be provided in place of the auxiliary notch portion 62, or a thin-walled portion may be provided in place. The same operation can be achieved by configuring

The skin portion 5 and the rib portion 6 are made of ABS, AES
Rubber-reinforced styrene resins such as (acrylonitrile-ethylene-propylene rubber-styrene resin), ASA (acrylonitrile-styrene-acrylate resin),
Alternatively, injection molding is performed integrally using one of these alloy resins (a blend with a polycarbonate resin, a copolymer of α-methylstyrene or N-phenylmaleimide). Those using these rubber-reinforced styrene-based resins have excellent adhesiveness to an acrylic film, and it is very effective to mold at least the skin portion 5 with the resin.

The flexural modulus of the molded product was determined according to ASTM D-7.
It is 800 to 1900 MPa based on 90 standard, and high impact absorption performance is maintained. This flexural modulus is 800MP
If it is less than a, the ribs are too soft and the ribs easily buckle, and the skin portion 5 hits the inner panel 20, and the head injury value HIC specified in US Standard FMVSS-201
(D) rises, and the impact absorption performance tends to decrease.
On the other hand, if it exceeds 1900 MPa, it is too hard, and the HIC (d) tends to increase.

As shown in FIG. 2, the acrylic film 4 is formed by forming a printed layer 7 on which a predetermined pattern is printed on at least one surface of an acrylic base layer 8 made of an acrylic resin. It is welded to the surface side of the skin substrate 50 by the heat of the resin at that time. Specifically, the acrylic film 4 is welded by film in-mold molding in which the acrylic film 4 is previously arranged in a mold used for injection molding of the front pillar garnish 3F and molded.
First, the film base layer 8 constituting the acrylic film 4
A printing layer 7 on which a pile pattern is printed on at least one surface is provided, and then the acrylic film 4 is placed in a mold,
By heating and reducing the pressure, it is brought into close contact with the mold surface. next,
The acrylic film 4 and the molded product are integrated by melting and injecting and molding the resin material while the acrylic film 4 is suctioned to the mold surface. Thereafter, the molded product is taken out of the mold, and an extra film on the outer periphery is removed, thereby obtaining the pillar garnish 3F.

Here, it is also preferable to provide an adhesive layer in advance on the welding surface of the acrylic film 4 which is in close contact with the mold surface, whereby the bonding strength with the molded product is increased and the durability is improved. The performance is further improved. Specifically, a combination of a combination of vinyl chloride resin (PVC) and polyvinyl alcohol (PVA), an adhesive made of EVA, or the like, or a solution obtained by dissolving such an adhesive in a solvent is applied and dried. Or those coated with a hot melt adhesive are preferred embodiments.

The acrylic base layer 8 on which the predetermined pattern is formed by the printing layer 7 includes, for example, Sanduren manufactured by Kaneka Chemical Industry Co., Ltd., whose main component is methyl methacrylate (MMA).

The ultraviolet absorber to be added includes:
For example, Ciba Geigy's Tinuvin 320 etc. are mentioned. The amount of the ultraviolet absorber added is 0.5 to 10%, preferably 1 to 5%, and more preferably 1 to 3% in the acrylic film. When the addition amount is less than 0.5%, the light resistance may be insufficient.
The high price of UV absorbers results in high film prices. Sumitomo Chemical's Sumisorb
0.5 to 0.5 hindered amine light stabilizers such as TM-061
10%, preferably 1-5%, more preferably 1-3
%, Light resistance may be improved in some cases.

The thickness of the acrylic base layer 8 is not particularly limited, but is 50 to 150 μm, preferably 75 to 125 μm.
m, more preferably 100 to 125 μm. When the thickness of the substrate layer is less than 50 μm, the amount of transmitted ultraviolet light is large, and the resin layer under the film tends to accelerate the light resistance deterioration. On the other hand, if it exceeds 150 μm, it takes a long time to form a film at the time of molding, and the molding cycle may be lengthened.

As shown in FIGS. 2A and 2B, the printing layer 7 may be provided on the back side or the front side of the acrylic base material layer 8. Further, it may be provided on both sides of the acrylic base material layer 8. In particular, as shown in FIG. 2A, in the case where the printed layer 7 is provided on the back surface side of the acrylic base material layer 8 containing the ultraviolet absorbent, harmful ultraviolet light which causes resin deterioration by the base material layer 8 is absorbed. Thus, the ink of the printing layer 7 on the back side is also protected at the same time, and the light resistance and the abrasion resistance of the pattern can be improved.

The thickness of the printing layer 7 is not particularly limited.
It is 0.5-5 μm, preferably 1-3 μm, more preferably 1-2 μm. When the thickness of the print layer 7 is less than 0.5 μm, the print layer is thin, and as shown in FIG.
When printing is performed on the surface side of the acrylic base material layer 8, the molded article tends to be gradually not removed due to abrasion such as cleaning (wiping) after being mounted on the vehicle body. On the other hand, when the thickness exceeds 5 μm, it is difficult to obtain a sufficient thickness in a single printing, and the printing margin tends to increase. When the print layer 7 is provided on the surface side of the acrylic base material layer 8, it is preferable to further provide a transparent or translucent protective layer on the surface to impart abrasion resistance to the print layer 7.

Further, since it is desired that the pillar garnish and the roof side rail garnish of the vehicle interior have a matte finish, a matting agent is added to the acrylic film 4 in order to make the film itself matte. Is preferred. Examples of the matting agent include crosslinked polymethyl methacrylate and talc. The amount of the matting agent added is 0.5 to 15%, preferably 1 to 1 in the acrylic film.
0%, more preferably 4 to 10%. If the addition amount is less than 0.5%, the matting effect may be insufficient, and if it exceeds 15%, the surface properties tend to deteriorate.

The skin portion 5 and the rib portion 6 are integrally formed. Alternatively, the skin portion and the plate-like rib may be formed separately using a synthetic resin material, and may be clipped, thermally caulked, and bonded. A preferred embodiment is also one that is integrally combined using an agent or a double-sided tape fixing means.
When the skin portion and the rib portion are formed separately as described above, 1
It is preferable that the plate-like ribs are connected by more than three vertical ribs.

The rib portion 6 may be made of the same rubber-reinforced styrene resin as that of the skin portion 5 or an alloy resin thereof, but it is also preferable to use a polypropylene resin.

As shown in FIGS. 11 and 12, the interior member for a vehicle according to the present invention includes a roof side rail garnish 3S, a door waist garnish 9, a switch panel 10, or a cluster panel 11 in addition to a pillar garnish 3F of an automobile. Is also preferably used.

It was prepared and used as a resin material of Example 1 and Comparative Examples 1 to 4.

As a polypropylene resin conventionally used for pillar garnish, Novatec manufactured by Nippon Polychem Co., Ltd. was prepared and used as a resin material of Example 2 and Comparative Example 5.

On the other hand, as an acrylic film used in Examples 1 and 2, Sanduren SD manufactured by Kaneka Chemical Industry Co., Ltd. was used.
004 NALGT (thickness: 70 μm) was used for the acrylic base layer, and a pile-tone printing of 2 to 5 μm was performed on one surface.

A rayon fiber having a thickness of 3 denier was cut into a short fiber having a length of 0.5 mm.
The piles used for Nos. To 4 were prepared.

Examples 1 and 2 are pillar garnishes in which the acrylic film was brought into close contact with the inner surface of a molding die in advance and injection-molded using the rubber-reinforced styrene resin and polypropylene resin, respectively. Specifically, the printed layer of the acrylic film was placed in a mold facing the injection resin side, heated for several seconds with a heater, and then evacuated to bring the film into close contact with the cavity side of the mold. Then, while the film was being sucked, the rubber-reinforced styrene-based resin or polypropylene-based resin was injected to be integrally formed with the film. Thereafter, the formed pillar garnish was taken out of the mold, and the outer peripheral portion was trimmed.

Comparative Examples 1 and 5 are pillar garnishes in which the acrylic film was injection-molded using the rubber-reinforced styrene resin and the polypropylene resin, respectively, without being placed in a mold.

Comparative Examples 2, 3, and 4 are pillar garnishes obtained by kneading the pile into the rubber-reinforced styrene resin without forming the acrylic film in the mold. .

The pillar garnishes of the respective examples and comparative examples were molded using a 360 TON injection molding machine under the conditions of a screw rotation speed of 90 rpm and a nozzle set temperature of 260 ° C. Are the same as those shown in FIGS. The detailed dimensions are shown in FIGS. 9 and 10, and the dimension of the maximum protruding height of each plate-like rib was set to about 19.5 mm.

A polyurethane sheet having a hardness of 60 and a thickness of 13 mm was adhered to the surface of the falling weight regarded as a skin portion of the dummy head, and a three-directional acceleration sensor arranged at the center of gravity of the aluminum ball was used to measure three-directional acceleration. After removing the miscellaneous frequency, the accelerations were time-synthesized by graphing the accelerations, and the HIC (d) at 23 ° C. was obtained from the graph based on the equation described in the FMVSS-201 standard. At the same time, the presence or absence of surface cracks in the skin at the time of impact was examined.

The results are shown in Tables 8 and 9 below.

[Table 8]

[0071]

[Table 9]

According to Table 8, in the pillar garnishes of Comparative Examples 1 to 4 molded using the same rubber-reinforced styrene resin, the flexural modulus increased as the amount of pile added increased. It can be seen that the tensile elongation was reduced and the material was in a state of being easily broken by impact. As a result, in Comparative Example 1 in which the pile amount was 1% by weight,
Since the value of C (d) exceeds 1000, it is very difficult to maintain the high shock absorbing performance of the vehicle interior member by the conventional technique of kneading a pile and exposing a pattern. I understand. Note that the value of HIC (d) needs to be 1000 or less in order to satisfy the safety standard in the United States standard.

According to Table 9, in Examples 1 and 2 where an acrylic film was provided on the front side, both HICs were used.
(D) is a low value of 550, indicating that high impact absorption performance is maintained. The value of the flexural modulus of Example 1 was the same as that of Comparative Example 1 in which the pile was not added.

After exposure, the color difference was measured using Nippon Denshoku Industries Co., Ltd. Z-300A.

Table 10 shows the color difference ΔE after the light resistance test.

[0076]

[Table 10]

According to Table 10, the color difference ΔE of Example 1 was suppressed to a small value as compared with Comparative Example 2 having no acrylic film. And discoloration are effectively prevented,
It can be seen that the original shock absorption performance is maintained for a long time.

[0078]

According to the vehicle interior member of the present invention, since the acrylic film provided with the predetermined pattern is provided on the surface, a sharp pattern can be obtained on the surface while maintaining the light resistance of the resin. In addition, an increase in rigidity and a decrease in tensile elongation due to kneading of fibers are avoided, and high impact absorption performance can be maintained.
