Description of the Related Art As a vehicle, a building material, or a sound material, a heat insulating and sound absorbing material made of a porous material having both heat insulating property and sound absorbing property has been conventionally used. By the way, as a material having adiabatic and sound absorbing properties made of a porous material, for example, an inorganic fibrous porous material such as glass fiber or a synthetic resin foam material has been conventionally known. In many cases, the heat insulating and sound absorbing member is used in a state of being covered with a skin material made of a non-woven fabric for the purpose of improving the property and imparting water repellency against water wetting. When the heat insulating and sound absorbing member is covered with a skin material made of a non-woven fabric, particularly when the heat insulating and sound absorbing member is formed into a molded product having a complicated shape such as deep drawing, the heat insulating and sound absorbing member is covered with the skin material at the same time as the heat insulating and sound absorbing member is formed. There is a risk that wrinkles may occur on the surface of the skin material, or damage may occur in some cases, when joining the two. for that reason,
The skin material is joined after forming the heat insulating and sound absorbing member.

Maybe,
An adhesive may be applied by spraying between the skin material and the heat insulating and sound absorbing member, or a heat fusion film such as EVAPE film or a heat fusion sheet such as nonwoven fabric such as polyethylene may be interposed. In particular, when a heat-sealing sheet such as EVAPE film is interposed, the heat-insulating and sound-absorbing member is preferably laminated together with the skin material, which is preferable in terms of manufacturing efficiency and also in terms of adhesive strength.

Does not cause wrinkles or damage to the skin material.

有する。As is apparent from the above description, according to the present invention, the polyurethane foam is laminated on the back surface of the non-woven fabric even when the skin material is jointly coated with the heat insulating and sound absorbing member at the same time as the heat molding of the porous material. Therefore, the polyurethane foam does not absorb the stress applied to the skin material during molding and does not cause wrinkles or damage to the skin material.Therefore, as in the conventional method, the molding of the heat insulating and sound absorbing member and the joining of the skin material are performed in separate steps. There is no need to carry out, and it is possible to efficiently produce a heat insulating and sound absorbing material provided with a skin material made of a non-woven fabric. Further, particularly when heat-sealing is performed by inserting a heat-sealing sheet such as EVAPE between the heat insulating and sound absorbing member and the skin material, the heat insulating and sound absorbing material having a large bonding strength between the heat insulating and sound absorbing member and the skin material can be efficiently used. Has the effect of being manufacturable.
