This method is simple, can be automated, and is efficient, but on the other hand, an adhesive is also applied to trim residue that will be trimmed in a later step. This not only causes the trouble of separating the sheet-shaped sound insulation material of the trim residue and the bulky felt at the time of recycling, but also may deteriorate the quality of the recycled product unless the adhesive is removed. In addition, since the adhesive adheres to the trim blades during the trimming process, the cutting performance of the trims deteriorates, and the blades must be cleaned regularly. . The present invention has been proposed to solve these problems.

る。As a result of earnest research, the inventors of the present invention have been able to solve the above problems by a method of applying an adhesive in a required amount in a required area. The gist of is the application method of applying the adhesive to the sound insulating material when the sheet-shaped sound insulating material and the sound absorbing material are laminated by adhesion,
(1) A net-like material through which a liquid adhesive can permeate, and a portion where the adhesive cannot permeate partially is formed in a net-like material stretched in advance in a frame, and (2) the net-like material is a sheet-like sound insulation material. , And (3) apply liquid adhesive to the entire surface of the net,
(4) A method for applying an adhesive at the time of manufacturing a molded soundproofing material, which comprises removing the net-like material and (5) adhesively laminating a sheet-shaped sound insulation material and a sound absorption material. Exist in. The details will be described below.

By forming a non-transmissive portion in the hole for penetrating the wire harness to prevent the adhesive from penetrating, the adhesive can be applied only to a necessary portion in a necessary amount.

For example, the mesh of the mesh used is determined by the viscosity and the drying property of the adhesive used. Further, as a material for the net-like material, durability is naturally required, and a tough inorganic synthetic fiber material such as a synthetic resin fiber or glass fiber, a metal wire mesh, or the like is preferable.

れる効果は同じである。Any method may be used as a method of partially forming a portion where the adhesive cannot penetrate, but since a mesh having a mesh having a certain degree of coarseness is used, the outer peripheral portion cut by the trim is used. It is recommended to attach an impermeable material such as a film to the holes so that the adhesive is not applied. A portion corresponding to the trim outer peripheral portion and the hole portion is cut with a film or the like and attached to a predetermined portion of the mesh. The area of the part to be attached is
It is desirable to set the trim blade 1 to several cm larger than the actual outer peripheral portion and hole portion so that the adhesive does not adhere to the trim blade. A method of forming an impermeable portion with a resin film or a paint can be considered, but it is difficult to form a film when a mesh having a coarse mesh is used. Further, when the area where the adhesive is desired to be applied is smaller, the whole may be made an impermeable portion and only the adhesive-applied portion may be a net. The effect obtained in this case is the same.

も可能である。In applying the adhesive, the sound-insulating material may be overlaid with a net, and then the adhesive partially placed may be spread with a spatula like a silk screen.
A roller dipped in an adhesive may be applied by rolling, or by a brush or the like. Depending on the size of the applied part, it is possible to apply only the necessary parts manually, or automatic application by a machine is possible.

熱硬化型の接着剤も使用できる。As the adhesive to be used, a pressure-sensitive adhesive such as an acrylic adhesive or a rubber adhesive can be used without any particular limitation. However, when the viscosity of the adhesive is high, the mesh is likely to be clogged, and therefore when such an adhesive is used, maintenance such as periodic cleaning of the mesh is required. Even if the viscosity is not particularly high, if the product is left for a long period of time, clogging similarly occurs. Therefore, it is recommended to wash the mesh. Further, when heating is performed at the same time when the soundproof material is molded, not only the pressure-sensitive adhesive but also a heat-curable adhesive can be used.

As a sound absorbing material, a bulky felt raw material prepared by adding a phenol resin to a fibrous raw material was used. A wire mesh having a mesh of 0.5 mm was stretched on a frame, and a polyethylene film having a width of 1 cm was attached to a portion corresponding to the outer peripheral trim portion and the hole portion of the automobile dash insulator to form a mesh. Laminate a net-like material on a sheet-shaped sound insulation material,
An acrylic resin pressure-sensitive adhesive was applied to the entire surface by a roller to remove the meshes, and then a sound absorbing material was laminated and adhered to the sound insulating material. After molding the laminate, it was trimmed to obtain a molded soundproof material dash insulator 1.
