DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is, for example, an automotive floor mat
Mosquito - is relates to the pet door.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a structure in which a carpet (1) is lined with a synthetic resin-impregnated polyurethane foam layer (3) via a polyethylene sheet (2) for floor coverings of automobiles is known. Provided. The synthetic resin-impregnated polyurethane foam layer (3) is formed into a shape conforming to the bead shape of an automobile floor (4), and is used as an insulator and at the same time as the floor (4). It also serves to prevent the card shape from being felt from the surface of the carpet (1).

[0003]

However, in the above conventional structure, the compression ratio is partially different because the synthetic resin-impregnated polyurethane foam layer (3) is compression-molded into a shape adapted to the bead shape. In part A of FIG. 5, the compression ratio is large, so that the density of the foam layer (3) is high and the hardness is high. In part B, the compression ratio is low, so that the density of the foam layer (3) is low. And the hardness becomes lower. For this reason, there is a problem that uniform cushioning and smoothness cannot be felt from the surface of the carpet (1).

[0004]

The present invention SUMMARY OF] is a means for solving the conventional problems described above flexible polyurethane foam
Layer (13B) and flexible polyurethane foam containing synthetic resin
A layer (13A) which has been immersed to give formability.
A layer of tree fat impregnated flexible polyurethane foam (13A) on the floor shape
Backed laminate (13) molded into a suitable shape
A carpet (1) is provided.

[0005]

In the laminate (13) of the present invention, a soft polyurethane having moldability by impregnating with a synthetic resin
The surface of the foam layer (13A) is soft and not impregnated with synthetic resin.
Since the layer quality polyurethane foam (13B) are laminated, shaped so as to partially compress the thickness to the soft polyurethane foam layer (13A) is performed, in part on the hardness becomes high because its Soft plastic not impregnated with synthetic resin
The urethane foam layer (13B) provides uniform cushioning on the surface.

[0006]

The present invention will be described with reference to an embodiment shown in FIGS. 1 to 4. The laminate (13) is a flexible polyurethane foam layer (13 A) impregnated with a synthetic resin and provided with moldability. Flexible polyurethane foam layer not impregnated with synthetic resin (1
3B). Upper Kigo synthetic resin is a polyurethane resin, phenol - Le resins, melamine resins, urea resins, epoxy resins, monomers of the acrylic resin or the synthetic resin, -,
Oligomers, prepolymers and the like.

[0007] The laminate (13), the thickness is usually 12~15mm about soft quality polyurethane foam layer synthetic resin is impregnated (13A), the synthetic resin is not impregnated soft
The thickness of the porous polyurethane foam layer (13B) is usually 10-20.
mm. In the above laminate (13), soft polyurethane is used.
Tan foam layer (13A) and a soft polyurethane Tan foam layer (13B)
Adhesives and hot melt adhesive or the soft poly,
The urethane foam layer (13A) is adhered by leaching of the synthetic resin impregnated.

[0008] As shown in FIG.
(6) and a lower mold (7) are set in a carpet molding die (5), on which the carpet (1) is superimposed. The sheet (2) is backed, and the polyethylene sheet (2) has been heated and softened in advance in molding. The carpet
(1) and the laminate (13) are formed by the above-mentioned mold (5), and at the same time, the carpet (1) and the laminate (13) are bonded through the polyethylene sheet (2). Of the above laminate (13)
Flexible polyurethane foam layer (13A) and flexible polyurethane
The foam layer (13B) may be adhered in advance before molding or may be adhered in molding. Then, the soft material impregnated with the synthetic resin of the laminate (13) by the above molding is used.
The porous polyurethane foam layer (12A) is compression molded into a shape that conforms to the bead shape of the car floor (4) as shown in FIG.

[0009] In this way the flexible polyurethane foam layer
(13A), a part A having a high compression ratio has a high density and high hardness, and a part B having a low compression ratio has a low density and low hardness, but a flexible polyurethane foam not impregnated with a synthetic resin. > layer (13B) has a uniform cushioning, the soft polyurethane
The hardness variation of the tan foam layer (13A) is covered. Therefore, uniform cushioning and smoothness can be felt from the surface of the carpet (1).

[0010]

Accordingly, uniform cushioning and smoothness can be felt from the surface of the laminate of the present invention. If this is used as a backing material for a carpet, the carpet surface also has a uniform cushion. It has properties and smoothness, and has a very good feeling in use.
