(Problems to be Solved by the Invention) As described above, interior materials for automobiles are required not only to be lightweight and capable of being heat-formed, but also to have high rigidity in order to maintain shape retention during use. However, the above-mentioned conventional technology has the following drawbacks.
That is, when shaping the sheet, the entire foam sheet must be thermally deformed, which takes time, and the ceiling lining material sags because the heat resistance and mechanical strength are low.

不織布の伸縮性が大で寸法安定性が悪く、又、

In this case, the nonwoven fabric consists only of organic fibers,
The nonwoven fabric has high elasticity and poor dimensional stability, and

Because it is a mixed nonwoven fabric of organic fibers and inorganic fibers, and has excellent thermal dimensional stability and high rigidity, it requires a large amount of thermal energy to improve the fluidity of the resin and increase the impregnation efficiency. ,or,
Drying and removing the solvent or dispersion medium also requires a large amount of energy. Furthermore, this increases the size of the equipment, and on the other hand, the resin is impregnated in an amount greater than that required for bonding, which hinders weight reduction.

The above-mentioned organic fibers and inorganic fibers are mixed by dry or wet papermaking, and compressed with hot rolls, so that the inorganic fibers are intertwined and fixed between the organic fibers to form a mixed nonwoven fabric. As for the mixing ratio, if the ratio of inorganic fibers is high, the heat formability will decrease, and if the ratio of organic fibers is high, the heat resistance will decrease and the mechanical strength will decrease, so the weight ratio of organic fibers to inorganic fibers should be 95:5 to 30: Preferably it is 70.

In order to laminate a mixed nonwoven fabric onto a foam sheet, the foam sheet is usually heated at a temperature of about 10 to 20 degrees below the softening point of the foam sheet.
The mixed nonwoven fabric is preheated to a temperature about 20 to 40°C higher than the softening point of the organic fibers and passed through a heated roll to laminate the mixed nonwoven fabric on both sides of the foam sheet. At this time, it is preferable that the spacing between the hot rolls is 10 to 20% smaller than the total thickness of each material before preheating, and the hot roll passing speed is about 5 to 15 m/. By preheating the mixed nonwoven fabric in this way, the surface of the organic fibers is melted and fused with the common resin component contained in the foam sheet, and the similarly preheated inorganic fibers on the bonding surface melt the surface layer of the foam sheet. and embed it,
Once fixed, the mixed nonwoven fabric is laminated on both sides of the foam sheet. In addition, the fibers of the nonwoven fabric are also stabilized because the contact portions are fused together.

The laminate obtained as described above is punched into a desired size and shape, and the adequacy of the bonding strength is determined depending on whether or not peeling occurs at that time. The inventor said that the bonding strength was approximately 600g/
It was discovered that peeling does not occur at all if it is 25 mm or more, and furthermore, in order to obtain a bonding strength of 600 g / 25 mm or more, it is necessary to add a resin component that accounts for 30% or more by weight of the foam sheet and organic fibers. It has been found that it is necessary that the resin component that accounts for 30% by weight or more of the organic fibers contained in the organic fibers be a common component.

(Effects of the invention) Since the structure of the laminate of the invention is as described above, the organic fibers of the nonwoven fabric and the common components of the foam sheet are fused together, so the resins have good compatibility with each other and have a high adhesive strength. The organic fibers are also fused at the contact areas, and the inorganic fibers are intertwined between them, resulting in a stable nonwoven structure, resulting in a laminate with high bending strength and high rigidity. In addition, since the inorganic fibers are directly fixed to the foamed sheet together with the organic fibers, the expansion and contraction of the foamed sheet is greatly suppressed, and the dimensional stability during thermoforming or use is excellent, making it difficult to deform due to heat.

Furthermore, since no adhesive is used and there is no need to impregnate the fibers with a resin as a binder, there is no need for adhesive or impregnated resin, resulting in a lightweight product.

エネルギーが不要で設備も小さくてすむ。
In addition, there is no need for energy for resin impregnation, solvent, or drying of dispersed soot, and the equipment can be small.
