体で遮音・吸音特性を持つ。FIGS. 3 and 4 show a first embodiment of a vehicle interior material according to the invention with respect to a molded ceiling 11, and this molded ceiling 11 is composed only of a base material 12 of plastic cardboard. . As in the past, this base material 12 is formed in a sandwich structure with a corrugated core 13 and liners 14 and 15 disposed on the upper and lower sides of this core 13. Unlike conventional products, both are made of wood-based vinyl chloride composite resin material. This wood-based durable vinyl composite resin material is made by blending and kneading fine powder obtained by crushing wood chips into a vinyl chloride resin material and forming it into a board shape using an extruder. Since it contains wood powder, it is lightweight and inexpensive, and the fine pores of the wood powder have its own sound-insulating and sound-absorbing properties.

仕上りとなる。Therefore, when the above-mentioned wood-based vinyl chloride composite resin material is used for the core 13 and the liners 14 and 15 to form the base material 12 of the sandwich structure, these members can insulate sound from outside the vehicle and absorb sound inside the vehicle. As a result, the thickness H2 of the air layer 1B of the base material 12 can be made smaller than the conventional thickness Hl, and since the base material 12 is formed thinner by that amount, it is possible to take a large head clearance. It becomes possible. In addition, since the above-mentioned wood-based vinyl chloride composite resin material is based on vinyl chloride resin, it has good coloring, and the wood powder scattered throughout gives it a woody feel, allowing the lower liner 15 to be directly applied to the ceiling surface. can be used. Therefore, in this embodiment, the pad 4, skin 5, etc. on the lower surface of the base material 12 can be omitted, and the entire molded ceiling 11 can be molded thinly, and the manufacturing process can be simplified and the manufacturing cost can be reduced. It is possible to aim for Furthermore, in this embodiment, the weight of the molded ceiling 11 can be reduced, making it easier to handle. Furthermore,
Since vinyl chloride resin is suitable for high-frequency welding, the peripheral edge of the base material 12 can be welded using high-frequency welding, instead of the conventional polypropylene base material 3 that had to rely on adhesion. The result is easier and more beautiful than before.

ある。In the production of the base material 12 according to the second embodiment, the core 13 and the upper and lower liners 14 are formed by, for example, extrusion molding means.
15 are each formed into a board shape, and the core 13 is sandwiched between a pair of rollers 17 and 18 having grooves formed on the circumferential surface as shown in FIG. As shown in Fig. 6, the corrugated core 13 and the flat liner 14.15 are sequentially fed into the roller section 111.2'0 and heated and laminated to integrally form the base material 12 consisting of three layers. do. Incidentally, reference numeral 10 in FIG. 4 is a roof panel.

に使用することもできる。7 and 8 show other examples of the base materials 12a and 12b. In FIG. 7, the core 13a is formed of a corrugated wood-based vinyl chloride composite resin material, and the upper and lower liners are 14a,
15a is made of ordinary vinyl chloride resin, and in contrast to this, liners 14b and 15b are made of wood-based vinyl chloride composite resin, and the core 13b is made of ordinary vinyl chloride resin. That's what happens. In the former case, since the upper and lower liners 14a and 15a are made of ordinary vinyl chloride resin, high-frequency welding of the peripheral edges is easier than in the above embodiment, and in the latter case, For example, by using a soft vinyl chloride resin for the core 13b, elasticity can be imparted to the entire base material 12b, which is particularly effective when used as a core material for a floor carpet. In the embodiments shown in FIGS. 7 and 8, a resin other than vinyl chloride resin is used for the liners 14a, 15a and the core 13b.
It can also be used for

用することができる。The base material 21 shown in FIG. 8 is a two-layer molded product consisting of a corrugated core material 22 molded from a wood-based vinyl chloride composite resin material and a flat liner 23 molded from ordinary vinyl chloride resin. By attaching the core material 22 toward the vehicle body panel 24 (for example, a dash panel or a floor panel), it can be applied in place of the core material of conventional dash insulators or floor carpets.

The core material 22 and the liner 23 are molded by sandwiching a tube-shaped parison bonded with vinyl chloride resin between molds of a predetermined shape and blowing pressurized air into the inside, or by using a mold of a predetermined shape. By vacuum forming the two, it is possible to obtain an integrally molded product with good work efficiency.
