The present invention relates to an automotive ceiling interior material that is lightweight, has no heat deformability, and is easily molded, and a method for manufacturing the same. Traditionally, interior materials for automobile ceilings have been known, such as those made by heating and pressurizing corrugated cardboard, and those made by pasting modified polystyrene on both the top and bottom surfaces of a modified polystyrene resin foam and then heating and pressuring it. Although the former has the advantage of being inexpensive, it has the disadvantage that it cannot be deep drawn, while the latter can be deep drawn, but will deform if left in the high temperature of nearly 100℃ inside a car for a long time. There was a particular need for improvement in heat resistance. The ceiling interior material for automobiles of the present invention is intended to solve the above-mentioned drawbacks, and is made by impregnating both sides of a foam of a modified polystyrene resin made of a copolymer of styrene and maleic anhydride with a polyester resin. It is characterized by being made by heat-sealing nonwoven fabric. In addition, the method for producing an automobile ceiling interior material according to the present invention includes immersing a nonwoven fabric made of polyester in a solvent such as toluene in which a modified polystyrene resin made of a copolymer of styrene and maleic anhydride is dissolved; Alternatively, the nonwoven fabric is pre-impregnated with the modified polystyrene resin by hot-pressing a modified polystyrene resin sheet onto the nonwoven fabric, and the nonwoven fabric is first foamed by adding a foaming agent to the modified polystyrene resin and extruding it. A plate-shaped primary molded product is manufactured by heat-sealing both sides of the foam, and this primary molded product is further heated to cause the foam to be secondarily foamed to a semi-molten state, which is then molded into a predetermined male and female mold. It is characterized by being press-formed into a three-dimensional shape that follows the ceiling. Embodiments of the present invention will be described below with reference to the drawings.
Generally, modified polystyrene resin refers to a copolymer of styrene and maleic anhydride, a copolymer of styrene and methacrylic acid, or a copolymer of styrene and acrylic acid. The copolymer with acid is sold by Amcor Corporation in the United States, and in Japan by Sekisui Plastics Co., Ltd. or Nippon Styrene Paper Co., Ltd. under the trade name Dilark. When impregnating a polyester nonwoven fabric with this modified polystyrene resin, the dipping method shown in FIG. 1 or the laminating method shown in FIG. 2 is used. 1st
In the dipping method shown in the figure, a modified polystyrene solution 1 containing 5 to 25% by weight of modified polystyrene resin in various solvents such as toluene, xylene, tetrahydrofuran, and chlorinated solvents is prepared in a water tank 2, and is wound into a roll. A nonwoven fabric 3 made of polyester is passed through guide rollers 4, 5, and 6 to penetrate into a modified polystyrene solution 1. Then, this is carried into the drying chamber 7, and the nonwoven fabric 3 is impregnated with the modified polystyrene resin by blowing hot air at 100° C. to 200° C. by rotating a fan to evaporate the solvent. Also, the second
In the case of the lamination method shown in the figure, a thin modified polystyrene resin sheet 9 extruded from an extruder 8
and polyester nonwoven fabric 3 are polymerized, and this is sandwiched between a pair of hot press rolls 10, 10 whose surfaces are treated with Teflon resin, heated and pressed, and then fan 1
Cool in air according to step 1. In this way, the polyester nonwoven fabric 3' with modified polystyrene resin pre-impregnated between the fibers is heat-sealed on both sides of a plate-shaped foam that is primarily foamed by extrusion molding by adding a foaming agent to the modified polystyrene resin. do. That is, as shown in FIG. 3, a modified polystyrene resin to which a foaming agent has been added is put into an extrusion molding machine 12, and the modified polystyrene resin is primarily foamed by heating to extrude and mold a plate-shaped foam 13. The nonwoven fabrics 3', 3' impregnated in advance with modified polystyrene resin as described above are heat-sealed to both sides of the foam 13 by hot press rolls 14, 14. At this time, the modified polystyrene resin impregnated into the nonwoven fabrics 3' and 3' is
It fuses with the modified polystyrene resin on the surface, creating a completely integrated adhesive state using the same resin. 15 is the plate-shaped three-layer primary molded product 1 obtained in this way.
6 shows a fan for air cooling and curing. Next, this primary molded product 16 is carried into a heating chamber 17 equipped with an electric heater as shown in FIG.
The foam 13 covered by the nonwoven fabric of the primary molded product 16 is heated in an atmosphere of 105 to 140° C. to cause secondary foaming, expand its volume, and bring it into a molten state. At this time, the polyester nonwoven fabric bonded to the surface usually has a heat resistance of at least 180°C, so the modified polystyrene resin melts.
At temperatures of 100 to 140°C, the sheet-like form is maintained without deterioration. The primary molded product 16 whose interior has been molten flexibly in this way is pressure-formed in a press 19 equipped with predetermined male and female molds 18, 18, and deep-drawn into a three-dimensional shape that follows the ceiling surface of the automobile. It is something to do. FIG. 5 shows a pair of flat hot plates 21, 21 set in a press machine 20 instead of heating the primary molded product 16 by carrying it into the heating chamber 17 as described above.
The primary molded product 16 is kept at 105 to 140℃ between the hot plates.
In this case, the heat plates 21, 21, which are heat conductors, have a larger heat capacity and can reliably heat the primary molded product 16 to a predetermined temperature. There are advantages that can be achieved. Note that during the subsequent pressure molding using the press 19, unnecessary portions of the periphery of the molded product are cut off, but by dissolving the scraps in the solvent used in the dipping method, the modified polystyrene resin can be reused without waste. It is not necessary to incinerate the scraps, which is effective in preventing pollution, and is also economically beneficial. The automobile ceiling interior material obtained in this way is a composite material in which polyester nonwoven fabric is adhered to the surface of the foam, so it is resistant to impact, and even if left in the high temperature of a car for a long time, the ceiling There was no deformation such as sagging, and the heat resistance was significantly improved. The following table compares the heat resistance of the conventional ceiling interior material (made by pasting modified polystyrene sheets on both the upper and lower surfaces of the above-mentioned modified polystyrene resin foam) and the ceiling interior material according to the present invention. shown in the figure
The periphery of a flat plate measuring 1000mm x 1500mm is fixed and held horizontally like a normal car ceiling, and then
This graph shows the sag distance (mm) at each point when the sample was left in an atmosphere of 85°C for 23 hours, then brought to room temperature for 1 hour, and this process was repeated three times.

As described above in the embodiments, the method for manufacturing an automotive ceiling interior material according to the present invention involves impregnating a nonwoven fabric with a modified polystyrene resin in advance and heat-sealing it to both sides of a primary foamed modified polystyrene resin foam. An integral bonding state using the same material is obtained, and excellent product strength as a composite material is achieved. Furthermore, the nonwoven fabric fused on both sides in this way undergoes secondary foaming by heating and becomes easier to handle when the foam is in a semi-molten state. When press-molded by male and female molds, the semi-molten foam flows freely between the nonwoven fabrics on the upper and lower surfaces, and the desired deep-drawn shape along the ceiling surface can be formed without difficulty. In addition, the automobile ceiling interior material manufactured in this way has highly heat-resistant polyester nonwoven fabric integrally fused to both sides of the modified polystyrene resin foam, so it has high heat resistance and can be left at high temperatures for long periods of time. It has the advantage of being extremely useful for automobiles because of its low deformation.
