産業上の利用分野
本発明は、ルーフ基材等として用いる車輛用内
装材の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for producing a vehicle interior material used as a roof base material or the like.
従来の技術
従来、例えばルーフ基材等の車輛用内装材は、
断熱性や吸音性に優れしかも寸法収縮が少ないと
ころからガラスウールをベースにし、その表面性
並びに剛性を補足するべく表裏面に不織布をホツ

いる。Conventional technology Conventionally, vehicle interior materials such as roof base materials,
It is manufactured using glass wool as its base due to its excellent heat insulation and sound absorption properties as well as its low dimensional shrinkage, and by laminating nonwoven fabric on the front and back sides with hot melt adhesive to supplement its surface properties and rigidity.
発明が解決しようとする問題点

的に引張強度が劣りしかもガラスウールの脆さと
相俟つて、強度的に十分な車輛用内装材として形
成することができない。Problems to be Solved by the Invention However, in this method for producing interior materials, the melting temperature of the hot melt is approximately 100 to 170°C, and the temperature at which glass wool can be laminated is more than 200°C, so the temperature contact point between the two is extremely high. The narrow space makes it difficult to set the temperature appropriately; if the temperature is insufficient, even if the hot melt melts, the glass wool will not reach the molding temperature, or if it is heated too much, the hot melt will penetrate into the glass wool, causing problems. This may also lead to poor adhesion. In addition, the nonwoven fabric attached to the front and back surfaces is inferior in tensile strength as a material, and combined with the brittleness of glass wool, it cannot be formed as a vehicle interior material with sufficient strength.

いる。Means for Solving the Problems In the method for manufacturing a vehicle interior material according to the present invention, a slab material is superimposed on glass wool and heated to 200°C.
The material is heated and compressed at the above temperature, and the impregnated resin exuding from the glass wool is adhered to the slab material by the heating and compression, and the slab material is integrally bonded to the glass wool as a high-strength, high-density layer. .

（２方向）によりスラブ材の成形時における折れ
皺等が出ない。Function: When manufacturing vehicle interior materials in this way, the temperature for heat-pressing the slab material is preferably 200°C or higher, and since the temperature conditions are almost the same as for glass wool, the temperature can be easily set, and the temperature can be easily adjusted. By heating and melting the impregnated resin and allowing it to seep out, it is possible to attach it to the slab material for reliable bonding, and also to form a slab material by compressing the slab material and bonding it to glass wool as a high-strength, high-density layer. Combined with this material, it will be possible to manufacture high-strength interior materials. Furthermore, due to the elongation characteristics (two directions) of the slab material, creases and the like do not appear during molding of the slab material.
実施例

い得るものであり、ガラスウール１の表裏の各シ

圧着することにより形成されている。 This vehicle interior material can be used, for example, as a roof base material, and is formed by pressing slab materials 2 and 3 such as urethane onto the front and back sheet surfaces of glass wool 1 under heat.
ガラスウール１並びに各スラブ材２，３はシー

略同じな200℃以上で220℃程度が最適である。 The glass wool 1 and each of the slab materials 2 and 3 are formed into sheets, and three sheets can be stacked and pressed together using a hot press.
The glass wool 1 has a thickness of about 20 to 50 mm, and the slab materials 2 and 3 have a thickness of about 20 to 50 mm.
It has a thickness of about 5 mm and is particularly suitable.
A material having a thickness of about 2.5 to 3 mm can be used. The pressure of the hot press should be 5 to 8 K/ cm2 , and the heating temperature should be such that the reaction curing temperature of the phenolic resin impregnated in glass wool 1 at about 8% by weight is 200°C or higher, and the temperature suitable for bonding the glass wool. The optimal temperature is 200°C or higher, which is approximately the same as the suitable temperature for heat-pressing the slab materials 2 and 3, and about 220°C.

形成されるようになる。 When glass wool 1 and slab materials 2 and 3 are stacked and heated and pressed so that slab materials 2 and 3 are located on the surface side, the glass wool 1 is usually 8% by weight.
The phenolic resin that has been impregnated to some extent oozes out and adheres to the slab materials 2 and 3. With the phenolic resin, the slab materials 2 and 3 are bonded to the glass wool 1, and each layer 1', 2', and 3' is compressed from its original thickness and formed into a relatively thin and high-density layer. It becomes like this.

め、温度条件等が問題にならない。 When manufacturing vehicle interior materials in this way, the applicable temperature for laminating the slab materials 2 and 3 is 200°C or higher, which is approximately the same as that for the glass wool 1, so the laminating temperature can be easily set and each layer ', 2', and 3' can be reliably joined. In addition, since the front and back surfaces are formed of high-density layers 2' and 3' of slab material, the rigidity can be increased by about 1.5 times or more compared to the one in which nonwoven fabric is laminated. In addition,
When this interior material is used as a roof base material, a skin material 4 such as cloth or synthetic resin is pasted on the front side.
The skin material 4 can be bonded with an adhesive such as hot melt, and since this bonding is done in a separate process, temperature conditions etc. do not matter.
