More specifically, the present invention relates to a method for producing an interior material that can be suitably used for automobile interior materials such as rear packages. [Prior Art and its Problems] Conventionally, automobile interior materials such as rear passenger compartments have been made by bonding a nonwoven fabric with a soft texture to a base material with excellent mechanical strength. Such interior materials usually include a base material such as wood stock made of a thermoplastic resin mixed with wood chips, a film made of a thermoplastic resin such as polypropylene on one surface, and a synthetic resin emulsion on the upper surface. A nonwoven fabric that has been impregnated on one side and subjected to a backing treatment is provided, and then the wood stock and the nonwoven fabric are integrated through the film using heating and pressing means such as a heat press. However, the above-mentioned automobile interior materials require a film between the nonwoven fabric and the base material, making the manufacturing process extremely complicated. In view of the above-mentioned problems, the present inventors have developed a method for manufacturing interior materials that does not require a film between the non-woven fabric and the base material and allows the non-woven fabric to be directly bonded to the base material. After extensive research, we found that if one surface of a nonwoven fabric is impregnated with a binder made by adding thermoplastic resin powder during the backing process, and the binder-impregnated surface of the nonwoven fabric is pressed against the base material, We discovered a completely new fact that interior materials can be easily obtained,
The present invention has now been completed. [Means for Solving the Problems] That is, in the present invention, one surface of a nonwoven fabric is impregnated with a binder made of a synthetic resin emulsion and a thermoplastic resin powder, and after drying, a base material is applied to the binder-impregnated side of the nonwoven fabric. The present invention relates to a method for producing an interior material, which is characterized by adhesive bonding. [Operations and Examples] According to the method for producing an interior material of the present invention, when a nonwoven fabric is impregnated with a binder, a heat-fusible resin powder is simultaneously attached to the nonwoven fabric, and a synthetic resin emulsion is impregnated into the nonwoven fabric. However, the heat-fusible resin powder is not impregnated into the nonwoven fabric but forms a layer on its surface, so when adhesive means such as thermocompression bonding are applied, the binder-impregnated surface and the base material are firmly bonded. It is. Nonwoven fabrics used in the present invention include synthetic fibers such as polyester fibers, polyethylene fibers, polypropylene fibers, polyvinyl chloride fibers, polyvinylidene chloride fibers, polyamide fibers, ethylene-vinyl acetate copolymer fibers, rayon fibers, and acetate fibers. Examples include semi-synthetic fibers such as fibers, and nonwoven fabrics made of natural fibers such as cotton and wool. Among these, polyester fibers are particularly preferred as interior materials because they have excellent weather resistance and heat resistance. Conventional methods such as fiber bonding, print bonding, needle punching, and hydroentanglement can be used to create a nonwoven fabric, but depending on the thickness, strength, formability, etc. of the nonwoven fabric, The needle punch method is particularly preferred. The binder used in the present invention consists of a synthetic resin emulsion and a thermoplastic resin powder. Examples of the synthetic resin emulsion include styrene-butadiene, ethylene-vinyl acetate, ethylene-vinyl chloride, ethylene-vinyl chloride-vinyl acetate, acrylic-styrene, acrylic ester, and vinyl acetate resin emulsions. Any conventionally used material can be suitably used. The concentration of the synthetic resin emulsion usually ranges from 5 to 65%, although it varies depending on the type.
It is adjusted and used so that As the thermoplastic resin powder, resin powders such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polystyrene, and polyamide may be used alone or in combination of two or more.
The particle size of these resin powders is preferably 30 to 400 mesh, particularly preferably 50 to 250 mesh. If the particle size of the resin powder exceeds 400 meshes, more of the resin powder will enter the inside of the nonwoven fabric and accumulate on the surface of the nonwoven fabric, making it impossible to form a layer. If the particle size is less than 30 meshes, the layer of resin powder formed will have large irregularities. I get used to it. In addition,
The shape of the resin powder is preferably flat or whisker-like rather than spherical because it is easier to accumulate on the surface of the nonwoven fabric. Such thermoplastic resin powder is emulsion 100
It is preferable to add 10 to 200 parts, particularly 50 to 150 parts, per part (by weight, the same applies hereinafter). If the amount of the thermoplastic resin powder added is less than 10 parts, the adhesive strength between the nonwoven fabric and the base material may be insufficient and peeling may occur, and if it exceeds 200 parts,
They cannot be uniformly dispersed in the emulsion, making production difficult and increasing production costs. In this way, the binder used in the present invention is obtained, and if necessary, the binder may further contain a cellulose-based, alginic acid-based or polyacrylic acid-based thickener; a phosphoric acid-based, bromine-based, or chlorine-based compound; antimony trioxide; Flame retardants such as ammonium hydroxide; dispersants such as pigments; PH regulators such as aqueous ammonia; wetting agent such as nonionic or cationic surfactants may be added as appropriate. Next, the binder obtained as described above is impregnated onto one surface of the nonwoven fabric while dispersing the thermoplastic resin powder by means such as stirring so that the emulsion and the thermoplastic resin powder are uniformly mixed. Binder attachment methods include coating, impregnation,
Examples include dipping and spraying, but any of these methods may be employed in the present invention. In the present invention, the binder is impregnated only on one surface of the nonwoven fabric and not on the other surface because of the texture of the nonwoven fabric,
If the purpose is to take advantage of the color, appearance, etc., but it is not necessary to take advantage of the texture of the nonwoven fabric, the other surface of the nonwoven fabric may also be impregnated with a binder, and the entire nonwoven fabric may be impregnated with the binder. It may be impregnated. Note that the surface opposite to the binder-impregnated surface of this nonwoven fabric is usually the surface of the interior material, so in addition to the above-mentioned texture, when surface resistance such as abrasion resistance and good appearance are required, the above nonwoven fabric can be used. It is desirable that resin be printed on the surface. By printing the resin in this way, it is possible to obtain surface resistance without impairing the texture or moldability of the surface of the interior material, and by selecting a variety of printed patterns, the interior material can have an excellent appearance. . Suitable resins for printing include acrylic resin and polyester resin. Further, the amount of resin applied varies depending on the amount of synthetic resin emulsion, but usually 5 to 15 g/m 2 is printed. By the way, the ratio of the nonwoven fabric weight (F) to the solid content (B) of the binder (hereinafter referred to as F/B) is 60/40.
-95/5, particularly preferably in the range of 70/30 - 90/10. If the F/B is larger than 60/40, the proportion of resin increases, resulting in a hard texture, high manufacturing costs, and 95/5.
If it is smaller than , the punching effect will be insufficient,
This results in an interior material with poor durability. Further, the amount of thermoplastic resin powder in the binder is preferably in the range of 5 to 50 g/ m2 , particularly 10 to 30 g/ m2 ; if it is less than 5 g/ m2 , sufficient adhesive strength cannot be obtained, and the There is a risk of peeling between the material and the nonwoven fabric, and if it exceeds 50 g/m 2 , it will be difficult to form a uniform resin powder layer on the surface during binder impregnation. In this way, a nonwoven fabric impregnated with a binder is obtained, and the emulsion in the binder is impregnated into the nonwoven fabric, but the thermoplastic resin powder is not impregnated into the nonwoven fabric, but forms a layer on the surface of the nonwoven fabric. . Next, an interior material is obtained by adhering the binder-impregnated surface of the binder-impregnated nonwoven fabric obtained above to a base material. Wood stock, resin felt, cardboard, foamed resin sheet, etc. are used as the base material. In addition, "wood stock" here refers to a resin made by adding 30 to 60% wood chips to a resin such as polypropylene. The adhesion between the nonwoven fabric and the base material is achieved by overlapping the surface of the nonwoven fabric to which the thermoplastic resin powder is attached and the base material, and pressing the nonwoven fabric from the upper surface by, for example, hot pressing or a base heated to 170 to 190°C in advance. This is done by overlapping the material and the resin powder-adhered surface of the nonwoven fabric and melting the thermoplastic resin powder by means such as cold pressing. Press pressure in the above adhesive means is 150-300
It is about g/ cm2 . The interior material thus obtained is used as it is or after being cut or molded into a predetermined shape and used as an automobile interior material such as a rear package, trunk interior material, overhead lining, etc. Next, the method for manufacturing an interior material of the present invention will be described in more detail based on Examples, but the present invention is not limited to such implementations. Example 1 After forming a web made of polyester fiber (fineness: 3 denier, fiber length: 64 mm), a punch felt nonwoven fabric (basis weight: 200 g) was formed using the needle punch method (needle density: 150 pieces/cm 2 , needle depth: 10 mm). / m2 ,
Thickness: 3.0mm). The binder shown in Table 1 was foamed on one surface of the obtained nonwoven fabric and impregnated to achieve a solid content of 50 g/m 2 (thermoplastic resin powder 17 g/m 2 , solid content in the emulsion).
A binder-adhered nonwoven fabric with an F/B ratio of 80/20 was obtained by applying the binder at a weight of 17 g/m 2 and 16 g/m 2 on the other side. Next, 50% polypropylene resin and 50% wood chips.
Cook the Utsudo stock in the oven at 190℃.
After heating for 3 minutes to soften, the nonwoven fabrics were immediately layered so that the binder-impregnated surfaces were in contact with each other, and then pressed using a cold press machine (pressing pressure: 300 g/cm 2 ).
was pressed for 2 minutes to produce an interior material. As for the physical properties of the resulting interior material, the peel strength between the nonwoven fabric and wood stock was examined using the following method. The results are shown in Table 2. (Peel strength) Punch out the interior material into a 5 cm x 15 cm piece to use as a sample piece.
This was pulled using a tensile tester at a pulling speed of 10 cm/min to examine the peel strength between the base material and the nonwoven fabric.

The manufacturing process is simple because there is no need to go through the complicated process of interposing a film between the nonwoven fabric and the core material as in the past. In addition, the resulting interior material has a thermoplastic resin powder that serves as an adhesive that forms a uniform layer on the surface of the nonwoven fabric.
Since the nonwoven fabric and the core material are adhered to each other while being firmly held, it has the effect of having good peel strength.
