Description

【Technical Field】 【0001】 The present invention relates to an adhesive resin composition and a thermoplastic resin composition having excellent adhesiveness to adhesives, different resins, paints, metals, or glasses, and a method for producing the same. The present invention also relates to an adhesive sheet and a laminate using this adhesive resin composition, and a synthetic resin molded body using this thermoplastic resin composition. 【Background Art】 【0002】 Conventionally, adhesives have been used to adhere thermoplastic resins to adherends such as different resins, paints, metals, and glasses. However, there has been a problem that sufficient adhesiveness cannot be obtained. 【0003】 As an example where adhesiveness between different materials is required, there is a flocked synthetic resin molded body, that is, a synthetic resin molded body having piles planted on the surface via an adhesive layer. A typical synthetic resin molded body is an automotive weatherstrip as a filling member attached to an automotive window (around the window glass lifting opening of the door) in order to prevent intrusion of gap wind, rain, etc., and further to remove glass stains when the glass is lifted or lowered by rubbing with the piles. The weatherstrip is provided such that the piles are located on the side in contact with the window glass. [[ID=!]] 【0004】 Conventionally, such a synthetic resin molded body has been manufactured by electrostatically flocking piles such as nylon short fibers onto a substrate made of a polyolefin-based resin or metal via an adhesive layer, but the adhesiveness between the substrate and the piles has not been sufficient. 【0005】 In order to enhance adhesiveness, surface treatments such as corona treatment and primer treatment have also been performed. Performing such treatments is not industrially preferable due to the increase in costs such as equipment investment for installing the surface treatment apparatus and its maintenance costs, and the increase in processes for primer treatment. There is also a problem that the treatment agent used for primer treatment leads to an environmental load. 【0006】 To address these challenges, a technology is being used that introduces functional groups into thermoplastic resins. For example, maleic anhydride-modified polyolefins, which are obtained by modifying olefin resins with maleic anhydride to improve adhesion to adherends and adhesives, are known (see Patent Document 1). Furthermore, a modified polyester elastomer is known in which a polyester thermoplastic elastomer, obtained by copolymerizing a polyester resin with polytetramethylene ether glycol, is modified with maleic anhydride (see Patent Document 2). 【0007】 [Patent Document 1] Japanese Patent Application Publication No. 9-278956 [Patent Document 2] Japanese Patent Publication No. 2002-155135 【0008】 In recent years, as the needs for products and parts have diversified, such as the aforementioned molded synthetic resin articles, which combine thermoplastic resins not only with other resins but also with paints, metals, glass, etc., there is a demand for improved adhesion between the adherend and the thermoplastic resin. Furthermore, from the perspective of reducing equipment costs and maintenance costs, reducing environmental impact, and streamlining processes, there is a need to obtain sufficient adhesion without requiring corona treatment or primer treatment. 【0009】 However, the modified polyolefins and modified polyester elastomers described in Patent Documents 1 and 2 had room for improvement in terms of adhesive strength. [Overview of the project] 【0010】 The present invention aims to provide adhesive resin compositions and thermoplastic resin compositions that exhibit excellent adhesion to adhesives, different resins, paints, metals, or glass. The present invention also aims to provide adhesive sheets and laminates using this adhesive resin composition, and molded articles made of synthetic resin using this thermoplastic resin composition.

In this invention, the POLYTETRAHYDROFURAN calibration kit from POLYMERLABORATORIES, UK was used for GPC calibration. The number-average molecular weight (Mn) of polytetramethylene ether glycol used in the examples and comparative examples described below was also measured using this method. 【0040】 Polyalkylene ether glycols are available commercially. For example, the PTMG series and BioPTMG series manufactured by Mitsubishi Chemical Corporation can be used. 【0041】 Polyalkylene ether glycol may be used alone, or two or more types with different compositions and physical properties may be used in combination. 【0042】 <Component (c): Acids and / or derivatives thereof> Unsaturated carboxylic acids are preferably used as the acid for modification. Specifically, the acid of component (c) and / or its derivative is preferably the unsaturated carboxylic acid and / or its derivative, which is component (c1). 【0043】 Unsaturated carboxylic acids are not particularly limited, but examples include acrylic acid, methacrylic acid, maleic acid, fumaric acid, itaconic acid, hymic acid, and citraconic acid.

If the amount of acids and / or their derivatives used is above the lower limit, the resulting resin composition tends to have good adhesion. If the amount of acids and / or their derivatives used is below the upper limit, the generation of unreacted substances and by-products is suppressed, which tends to prevent deterioration of the product appearance due to fish eyes, blemishes, etc. in molded articles using the resulting resin composition, and also tends to suppress a decrease in adhesion. 【0048】 <Component (d): Peroxide> Peroxides are used as radical initiators in the graft modification of modified polyalkylene ether glycols of component (B) (including component (B2)). 【0049】 Both aromatic organic peroxides and aliphatic organic peroxides can be used as peroxides.

Specifically, preferred peroxides are dialkyl peroxides such as di-t-butyl peroxide, dicumyl peroxide, 2,5-dimethyl-2,5-di(t-butylperoxy)hexane, and 2,5-dimethyl-2,5-di(t-butylperoxy)hexyn-3, or peroxyesters such as t-butyl peroxybenzoate, t-butyl peroxy-2-ethylhexanoate, 2,5-dimethyl-2,5-di(benzoylperoxy)hexane, and 2,5-dimethyl-2,5-di(benzoylperoxy)hexyn-3. 【0052】 The amount of peroxide used is usually 1 part by mass or more, preferably 2 parts by mass or more, and usually 30 parts by mass or less, preferably 25 parts by mass or less, per 100 parts by mass of polyalkylene ether glycol of component (b) (including component (b2)). By using an amount of peroxide above the lower limit, graft modification can be performed efficiently, and by using an amount below the upper limit, the generation of odor due to the reaction residue of the peroxide can be reduced. 【0053】 <Graft Degeneration> To produce a modified polyalkylene ether glycol of component (B) or component (B2), the polyalkylene ether glycol is modified using the aforementioned component (b) or component (b2), component (c), preferably component (c1), and the peroxide of component (d) in predetermined proportions. 【0054】 Modification of polyalkylene ether glycol can be carried out, for example, by melting the polyalkylene ether glycol and adding an unsaturated carboxylic acid and / or its derivatives and a peroxide to perform graft modification. Alternatively, it can be carried out by dissolving the polyalkylene ether glycol in a solvent and adding an unsaturated carboxylic acid and / or its derivatives and a peroxide to perform graft modification.

The outer wall of the cylinder is surrounded by a heater and a cooling jacket, allowing the compound material to be heated or cooled from the outside. 【0059】 Modification using a kneader is typically carried out at a temperature of around 160-350°C, according to the settings of the kneader used. As described below, the modification of polyalkylene ether glycol can be carried out in the presence of a thermoplastic resin of component (a) (including components (a1) and (a2)). 【0060】 [Ingredients (e): Hydrocarbon rubber softener] The resin composition of the present invention preferably contains a hydrocarbon-based rubber softener as component (e) in order to soften the resulting resin composition, increase its flexibility and elasticity, and improve the processability and fluidity of the resulting resin composition. 【0061】 Hydrocarbon-based rubber softeners include mineral oil-based softeners and synthetic resin-based softeners.

If the amount of component (g) used is above the lower limit, insufficient crosslinking is less likely to occur, and deterioration of physical properties and thermoplastic moldability is less likely to occur. If the amount of component (g) used is below the upper limit, over-crosslinking is less likely to occur, and deterioration of physical properties and thermoplastic moldability is less likely to occur. 【0089】 [Molding / Applications] The resin composition of the present invention can be molded into a molded article by commonly used molding methods, such as injection molding, extrusion molding, hollow molding, compression molding, and vacuum molding. Among these, molded articles obtained by injection molding and extrusion molding are preferred. After these molding processes, the article can also be modified by secondary processing such as lamination molding and thermoforming. 【0090】 Since the resin composition of the present invention can adhere to adhesives, other resins, paints, metals, or glass, it can be used in a wide range of fields, including civil engineering and building materials (waterproofing materials, joint materials, window frames), sporting goods, industrial parts (multilayer hose tubes), home appliance parts (multilayer hoses), medical parts (multilayer medical containers), food parts (multilayer packaging films, containers, bottles, decorative packaging, labels), electric wires, general merchandise, and automotive parts (weatherstrips, ceiling materials, interior sheets, bumper moldings, side moldings, air spoilers, hoses, armrests, door trims, console lids, mats). 【0091】 [Adhesive sheet] The adhesive sheet of the present invention is made of the adhesive resin composition of the present invention. The adhesive sheet of the present invention can be manufactured by extruding the adhesive resin composition of the present invention. 【0092】 The thickness of the adhesive sheet of the present invention is preferably 10 μm or more, and particularly 50 μm or more, from the viewpoint of adhesiveness, mechanical strength, etc. On the other hand, from the viewpoint of flexibility and cost-effectiveness, the thickness of the adhesive sheet of the present invention is preferably 10 mm or less, and particularly 5 mm or less. 【0093】 The adhesive sheet of the present invention, which is made of the adhesive resin composition of the present invention, can be bonded to adhesives, different resins, paints, metals, or glass, and can therefore be used in a wide range of fields, including civil engineering and building materials (waterproofing materials, joint materials, window frames), sporting goods, industrial parts (multilayer hose tubes), home appliance parts (multilayer hoses), medical parts (multilayer medical containers), food parts (multilayer packaging films, containers, bottles, decorative packaging, labels), electric wires, general merchandise, and automotive parts (weatherstrips, ceiling materials, interior sheets, bumper moldings, side moldings, air spoilers, hoses, armrests, door trims, console lids, mats). 【0094】 [Laminate] The laminate of the present invention is a laminate comprising at least two or more layers, each layer consisting of an adhesive layer and a substrate layer made of the adhesive resin composition of the present invention. Specifically, examples include laminated sheets, laminated films, laminated tubes, etc. Here, "sheet" and "film" both refer to a planar molded body and are synonymous. 【0095】 The material constituting the base layer of the laminate of the present invention is not limited, but examples include metal and resin films. Furthermore, the layer configuration of the adhesive layer and the base layer, which are made of the adhesive resin composition of the present invention, is not limited, but it is preferable that these layers are adjacent to each other. 【0096】 When the base layer is a metal layer, the metal constituting the metal layer is not limited, but specifically, examples include aluminum, iron, copper, stainless steel, etc., with aluminum being preferred among them. 【0097】 When the base layer is a resin film, the resin constituting the resin film is not limited, but specifically, olefin polymers and olefin elastomers containing ethylene-vinyl alcohol copolymers, ethylene-vinyl acetate copolymer saponified products, polyvinyl chloride, polyvinylidene chloride, polyethylene, polypropylene, poly-4-methyl-1-pentene, polycarbonate resins, polyamide resins such as polyamide 6, polyamide 66, polyamide 6-66, and polyamide 12, polyester resins and polyester elastomers such as polyethylene terephthalate and polybutylene terephthalate, styrene resins and styrene elastomers, and thermoplastic resins such as acrylic resins are preferably used. In particular, when used in food or medical materials, it is preferable to have at least an ethylene-vinyl alcohol copolymer layer or a polyamide resin layer. 【0098】 These resin films may be laminated in two or more layers. Furthermore, the resin film may be stretched or unstretched, or a combination of both may be used. For example, the thermoplastic resin film may be uniaxially or biaxially stretched, in which case biaxially oriented polypropylene film is particularly preferred. Laminated with paper is also preferred. Moreover, the thermoplastic resin film may have a metal vapor-deposited on it, and films in which metal and resin are laminated can also be used. These may use multiple metal layers or resin layers. 【0099】 The form of the substrate layer is not limited to films or sheets, but may also be in the form of woven fabrics or nonwoven fabrics. Furthermore, the substrate may have a single-layer structure or a multi-layer structure. The method for creating a multi-layer substrate layer is not particularly limited and includes methods such as co-extrusion film lamination, dry lamination, wet lamination, hot melt lamination, extrusion lamination, and thermal lamination. Furthermore, these substrate layers may be pre-treated with various film processing treatments such as anchor coating, metal vapor deposition, corona discharge treatment, and printing. 【0100】 There are no particular restrictions on the thickness of the substrate layer, but it is usually around 5 to 100 μm. 【0101】 The laminate of the present invention may include any layer other than the adhesive layer made of the adhesive resin composition of the present invention and the aforementioned base layer. The materials constituting these layers are not limited, but are usually resin layers. For example, a laminate of any resin layer / adhesive layer made of the adhesive resin composition of the present invention / base layer can be constructed. If the arbitrary layer is a resin layer, the resin constituting the resin layer is also not limited, and specifically, the resin listed as component (A) in the present invention can be used, but preferably a polypropylene resin is used from the viewpoint of excellent co-extrusion with the resin composition of the present invention. 【0102】 Various conventionally known methods can be used to manufacture the laminate of the present invention, but extrusion lamination is particularly preferred. Extrusion lamination is a method of continuously coating and pressing a molten resin film extruded from a T-die onto the surface of a pre-manufactured substrate, and is a molding method that can perform coating and bonding simultaneously. Usually, lamination is performed on one side surface of the substrate, but it can also be done on both sides if necessary. Extrusion lamination is preferred because it allows for the fast and stable acquisition of a laminate. In particular, the adhesive resin composition of the present invention provides excellent moldability even when lamination is performed under high-speed conditions of 100 m / min or more, good adhesion to the substrate layer, and can maintain good adhesion to the substrate layer even in high-temperature and high-humidity environments. 【0103】 Extrusion lamination molding may use not only one type of substrate layer as a pre-formed film, but also two or more types of films. In this case, the molding may be performed by simultaneous lamination, or one substrate may be pre-formed using lamination molding, and then the other substrate may be laminated to it. Furthermore, the resin used for lamination is not limited to using only one type, but two or more types may be co-extruded. 【0104】 When extrude-laminating the adhesive resin composition of the present invention onto a substrate layer, the melt extrusion temperature of the resin composition is typically 180 to 320°C, preferably 200 to 310°C. If this temperature exceeds 320°C, moldability may decrease. Ozone treatment may be applied to the surface of the molten resin film of the resin composition of the present invention formed by extrusion lamination, in order to introduce polar groups. The amount of ozone treatment is 0.01 to 1 g / m² relative to the surface area of ​​the molten resin film. 2 It is preferable to do so. 【0105】 The laminate of the present invention may be laminated by the above method or the like, and then stretched to form a stretched film. In such cases, it is preferable to use an unstretched resin film or sheet as the base layer. Various conventionally known methods can be used to manufacture stretched films. The stretching direction may be uniaxial or biaxial, and the films may be manufactured by sequential stretching or simultaneous stretching. In addition, as one stretching method, an inflation film may be produced by inflation molding during the lamination process. 【0106】 When the laminate of the present invention is obtained by stretching, after stretching as described above, heat fixing may be performed, or it may be used as a product without heat fixing. If heat fixing is not performed, the laminate can be used as a shrink film because it has the property of shrinking when the stress is released by heating the laminate afterward. 【0107】 The thickness of each layer of the laminate of the present invention is not limited and can be arbitrarily set depending on the layer configuration, application, shape of the final product, required physical properties, etc. Typically, the total thickness of the laminate is 5 to 400 μm, more preferably 10 to 300 μm, and particularly preferably 20 to 200 μm. The thickness of the adhesive layer made of the adhesive resin composition of the present invention that constitutes the laminate is typically 0.1 to 100 μm, more preferably 0.3 to 50 μm, and particularly preferably 0.5 to 20 μm. The thickness of the resin layer laminated on the adhesive layer made of the adhesive resin composition of the present invention is typically 1 to 250 μm, more preferably 3 to 200 μm, and particularly preferably 5 to 150 μm. 【0108】 The laminate produced in this manner can be further subjected to various film processing treatments such as metal vapor deposition, corona discharge treatment, and printing. 【0109】 The adhesive resin composition of the present invention exhibits excellent adhesive strength characteristics to metal layers and resin films. Therefore, laminates using this composition can be suitably used for packaging various foods and beverages, pharmaceuticals and medical products, cosmetics, clothing, stationery, and other industrial materials and materials. 【0110】 [Synthetic resin molded body] The synthetic resin molded article of the present invention has piles implanted on a substrate made of polyolefin resin or metal via an adhesive layer, and an active portion is disposed between the substrate and the adhesive layer. The active portion may be a protrusion integrated with the main body (substrate), as in the seal lip of an automotive weatherstrip described later, or it may be a layered structure laminated on the surface of the substrate. 【0111】 [Base] The substrate consists of a chemically inert material, i.e., a polyolefin resin or a metal. The polyolefin resin may be a composition containing a thermoplastic elastomer in a proportion of typically 30% by mass or less. 【0112】 Examples of polyolefin resins constituting the substrate include homopolymers of α-olefins such as ethylene, propylene, butene-1, and 4-methylpentene-1, or copolymers thereof. In particular, random or block copolymers of propylene polymers, such as isotactic propylene and polypropylene, with α-olefins such as ethylene, butene-1, or hexene-1 are preferred. These polyolefin resins are commercially available from various companies under different brands, for example, "Novatec" manufactured by Nippon Polypropylene Co., Ltd. In the present invention, these commercially available products can be suitably used by selecting a brand suitable for extrusion molding. 【0113】 A composition of polyolefin resin and thermoplastic elastomer can be obtained by blending polyolefin resin, olefin-based or styrene-based rubber, and a softener (optional component), and then dynamically heat-treating the mixture in the presence or absence of an organic peroxide. Furthermore, other rubbers can be used in combination, as long as they do not impair the objectives of the present invention. 【0114】 The thickness of the polyolefin resin substrate is typically in the range of 0.5 to 10 mm, and is designed as appropriate depending on the application. 【0115】 Examples of metal substrates include various metal sheets with a thickness of 0.1 to 0.5 mm, and more specifically, sheets of iron or plated iron. 【0116】 [Active part] In the present invention, the active portion is the thermoplastic resin composition I of the present invention. The description of the resin composition of the present invention described above applies similarly to the thermoplastic resin composition I constituting the active portion, but as the thermoplastic resin of component (A1) constituting the thermoplastic resin composition I, a thermoplastic elastomer using an olefin-based elastomer and a propylene-based polymer is preferably used. 【0117】 As olefin-based elastomers, those described above in the description of the resin composition of the present invention can be suitably used. Among these, Mooney viscosity ML 1+4Ethylene-propylene copolymer elastomers with a viscosity (at 125°C) of 30 to 75 are preferred, and ethylene-propylene-non-conjugated diene copolymer rubber (EPDM) is particularly preferred. The EPDM may be an oil-expandable type containing oil beforehand, a non-oil-expandable type without oil, or a combination of both. Non-oil-expandable EPDM without oil beforehand is economically inexpensive. Oil-expandable EPDM tends to improve mechanical properties and moldability. For any type of EPDM, the Mooney viscosity in the oil-containing state is ML. 1+4 It is preferable to use it when the temperature (125℃) is between 30 and 75 degrees Celsius. 【0118】 Examples of the non-conjugated dienes mentioned above include dicyclopentadiene, 1,4-hexadiene, cyclooctadiene, methylenenorbornene, and ethylledenenorbornene, with ethylledenenorbornene being particularly preferred. 【0119】 A preferred example of an olefin-based elastomer is EPDM with an ethylene unit content of 55-75% by mass and a non-conjugated diene unit content of 1-10% by mass. A ethylene unit content of 55% by mass or more tends to improve extrusion moldability, while a content of 75% by mass or less tends to maintain flexibility. Here, flexibility is important, for example, as an elastic recovery function that suppresses glass vibration (holds the glass) in the active portion of an automotive weatherstrip's seal lip. 【0120】 Commercially available olefin-based elastomers can be used for this purpose. Specific examples of commercially available olefin-based elastomers include "Nordel (registered trademark) IP4760P" (manufactured by Dow Chemical), "EPT3070", "EPT3092M", "EPT3062EM", "EPT3072EM" (all product names: manufactured by Mitsui Chemicals, Inc.), and "EP24", "EP57C", "EP98", "EP505EC" (all product names: manufactured by JSR Corporation). 【0121】 Examples of propylene polymers include isotactic propylene and random or block copolymers of polypropylene with ethylene or α-olefins such as butene-1 and hexene-1. In particular, propylene polymers with a melt flow rate (MFR) of 0.1 to 35 g / 10 min at 230°C and a load of 21.18 N are preferred. Polymers with an MFR within the above range tend to be easier to extrude. 【0122】 When the thermoplastic resin composition I constituting the active part contains an olefin-based elastomer and a propylene-based polymer as the thermoplastic resin of component (A1), it is preferable that the content of the olefin-based elastomer is 70 to 90% by mass and the content of the propylene-based polymer is 10 to 30% by mass, relative to 100% by mass of the total of the olefin-based elastomer and the propylene-based polymer in component (A1). If the content of olefin-based elastomer in component (A1) is above the lower limit and the content of propylene-based polymer is below the upper limit, excellent flexibility tends to be obtained. If the content of olefin-based elastomer is below the upper limit and the content of propylene-based polymer is above the lower limit, excellent extrusion moldability tends to be obtained. 【0123】 The modified polyalkylene ether glycol, which is modified with an acid such as an unsaturated carboxylic acid and / or its derivative, and / or its derivative, of component (B) of the thermoplastic resin composition constituting the active part, is subject to the content of component (B) described in the description of the resin composition of the present invention, and the same applies to preferred components. 【0124】 The thermoplastic resin composition I constituting the active portion preferably contains 0.1 to 30 parts by mass of modified polyalkylene ether glycol (component B) per 100 parts by mass of the total of olefin elastomer and propylene polymer (component A1). From the viewpoint of stable adhesion, the lower limit of the content of component (B) is more preferably 0.2 parts by mass or more, and even more preferably 0.5 parts by mass or more. On the other hand, from the viewpoint of handling during manufacturing, the upper limit of the content of component (B) is more preferably 25 parts by mass or less, and even more preferably 15 parts by mass or less. 【0125】 [Adhesive layer] Adhesives used in adhesive layers are broadly classified into two types: emulsion-based and solvent-based. Emulsion-based adhesives include acrylic ester resins, acrylic ester-vinyl acetate copolymer resins, vinyl acetate resins, ethylene-vinyl acetate copolymer resins, urethane resins, epoxy resins, and synthetic rubbers (SBR, NBR). Solvent-based adhesives include epoxy resins, urethane resins, chloroprene resins, synthetic rubbers (SBR, NBR), vinyl acetate resins, and acrylic ester resins. Of these, a solvent-based, one-component, moisture-curing urethane resin with good water resistance is preferably used for automotive weatherstrips. 【0126】 [pile] Pile fabric is made by cutting long fibers into short fibers, and materials such as nylon, rayon, and polyester are used. For automotive weatherstripping, nylon, which has sliding properties, is preferably used. The pile thickness is usually 0.6 to 3.0 denier, and the length is usually 0.6 to 1.5 mm. 【0127】 [Manufacturing of molded products made of synthetic resin] There are no particular limitations on the method for manufacturing the synthetic resin molded article of the present invention. For example, it can be manufactured as follows. 【0128】 <Molding of the substrate and active part> Typically, extrusion molding is used to form the substrate. In this process, the polyolefin resin substrate material and the thermoplastic resin composition I, which will be the material for the active part, are co-extruded into a mold of the desired shape, thereby integrating the substrate made of polyolefin resin with the active part made of thermoplastic resin composition I. This can be easily done using known extrusion molding techniques. The same applies when using a metal sheet instead of polyolefin resin. 【0129】 <Formation of adhesive layer and flocking process> The substrate and active part extruded molded product obtained as described above is coated with adhesive on the surface of the active part to form an adhesive layer. Then, it is placed in a flocking machine and flocked. Before applying the adhesive, if necessary, auxiliary surface treatments such as degreasing to wash away fingerprints, machine oil, etc. that inevitably adhere to the surface may be performed. For applying the adhesive, a knife coater, roll coater, spray, brush, roller, etc. can be used as appropriate. 【0130】 For the flocking process, an electrostatic flocking method is preferred due to its high productivity and high flocking strength. A down-method is preferred, in which a molded body coated with adhesive is placed on a lower electrode, and charged piles are launched downwards to flock the fibers. After flocking, the product is heated and dried, and brushed to remove any remaining pile. 【0131】 [Automotive weatherstrips] The synthetic resin molded articles of the present invention are particularly suitable for use as weatherstrips for automobiles. 【0132】 Figure 1 is a schematic cross-sectional view of an example of an automotive weatherstrip (10), where (1) represents the main body (corresponding to the substrate mentioned above), (2) represents the seal lip portion (corresponding to the active portion mentioned above), and (3) represents the pile implanted in the seal lip portion (2) via an adhesive layer (not shown). Reference numeral (21) represents the seal lip portion where it is not necessary to implant pile. 【0133】 The main body (1) of the automotive weatherstrip (10) described above uses the aforementioned polyolefin resin or metal sheet, and the seal lip portion (2) uses the aforementioned thermoplastic resin composition I of the present invention. A solvent-based, one-component, moisture-curing urethane resin with good water resistance is preferably used for the adhesive layer. A nylon pile with a thickness of typically 0.6 to 3.0 denier and a length of typically 0.6 to 1.5 mm is preferably used for the pile (3).

A urethane-based resin adhesive, San-Grip TKS-63 (composed of urethane prepolymer, toluene, butyl acetate, methyl ethyl ketone, and 4,4-diphenylmethane diisocyanate) manufactured by Sanwa Polymer Industries, was applied to the surface of the molded sheet to a thickness of approximately 10 μm using a bar coater. While the adhesive was still wet, polyester tape (Polyco Tape, manufactured by Okuda Sangyo Co., Ltd., 17 mm wide) was placed on top, ensuring that no air bubbles were trapped between the polyester tape and the adhesive. The sheet was then dried in an 80°C oven for 30 minutes and left to stand at room temperature for 24 hours. The adhesive strength between the tape and the sheet was measured using a 180-degree peel test method (test speed 50 mm / min, peel distance approximately 50 mm, maximum test force measured) with a Shimadzu Autograph AG2000, referencing the ISO 8510-2:1990 standard. The adhesion between the resin composition and the urethane resin was evaluated based on this peel strength. Furthermore, the delamination surface of the test specimen after measuring the peel strength between the resin composition and the urethane resin was observed as the delamination mode. If delamination occurred near the interface between the resin composition sheet and the urethane resin adhesive layer, it was evaluated as interfacial delamination. If the resin composition sheet fractured, it was evaluated as material fracture. In this evaluation, material fracture means that the adhesion between the resin composition and the urethane resin is stronger compared to interfacial delamination. 【0147】 <Hardness Duro A> A 2mm thick sheet was formed at 190°C using a press molding machine (hydraulic jack type heating / cooling press, 200 x 200 mm, manufactured by Toyo Seiki Seisakusho) with a resin composition. The hardness of this sheet, duro A, was measured in accordance with JIS K6253. 【0148】 <eye discharge> Using a 20mm diameter single-screw extruder (L / D=22, full-flight screw with compression ratio=2.0) manufactured by Toyo Seiki Seisakusho, and a sheet-shaped die with a width of 40mm and a thickness of 0.5mm, extrusion molding was performed for 10 minutes under the following conditions: hopper temperature: 180℃, cylinder: 200℃, die: 200℃, screw rotation speed: 60rpm. After that, the molten resin composition clumps (die residue) adhering to the die and the molded product were visually inspected and evaluated according to the following criteria. ○: Almost no die buildup occurs in either the die or the molded product. ×: A large amount of die residue was generated in the die and molded product. 【0149】 <Confirmation of adhesion to metals and other resins> Using a resin composition, a 1 mm thick sheet was formed at 190°C using a press molding machine (hydraulic jack type heating / cooling press, 200 x 200 mm, manufactured by Toyo Seiki Seisakusho). With Mitsubishi Aluminum's Mitsubishi Foil (25 μm thick), which is aluminum, laminated onto the surface of the formed sheet, the sheet was pressed together at 200°C and a press pressure of 5 MPa for 3 minutes using the same press molding machine (hydraulic jack type heating / cooling press, 200 x 200 mm, manufactured by Toyo Seiki Seisakusho) to create a sample for adhesion evaluation. The adhesive properties of the obtained test specimens were confirmed by checking whether they could be peeled off by hand, and evaluated according to the following criteria. ○: Adhered. The test piece does not peel off even when bent by hand. ×: Not glued. It peels off easily when touched. In Example 17 and Comparative Example 18, the following resins other than aluminum were used, and their adhesive properties were evaluated in the same manner as for aluminum.
