The present invention relates to resin-metal laminates. Even if polypropylene is laminated with a metal such as aluminum, it does not have adhesive strength because polypropylene is a nonpolar material. Conventionally, in order to improve this adhesive strength, there have been methods to perform surface treatments such as electrical discharge treatment, chromic acid treatment, flame treatment, and various types of etching on the surface of polypropylene and metal, and methods to use modified polyolefin in which maleic anhydride is grafted onto polyolefin ( Special Publication No. 42-10757,
47-4822, etc.), and a method using a composition in which a hydrocarbon synthetic elastomer is blended with an acid-modified polyolefin (Japanese Patent Application Laid-open No. 52-80334). However, these methods require time and expense for surface treatment, insufficient adhesive strength, or the addition of elastomers may result in poor heat resistance,
It has the disadvantage of reduced oil resistance and solvent resistance. The present invention aims to eliminate such drawbacks and provide a resin-metal laminate with high adhesive strength. That is, the present invention provides (A) 99 to 40 parts by weight of a crystalline polypropylene modified with an unsaturated carboxylic acid or its anhydride or a mixture of said polypropylene and unmodified crystalline polypropylene, and (B) an ethylene homopolymer or ethylene. - A resin-metal laminate comprising a resin layer comprising 1 to 60 parts by weight of a vinyl acetate copolymer and a metal layer. In the present invention, the crystalline polypropylene modified with an unsaturated carboxylic acid or its anhydride used as component (A) refers to a propylene homopolymer, a polymer containing ethylene, butene-1, hexene-1, etc. mainly composed of propylene. For copolymers or mixtures thereof, unsaturated carboxylic acids such as acrylic acid, maleic acid, itaconic acid, fumaric acid, crotonic acid, citraconic acid, sorbic acid, mesaconic acid, angelic acid or their anhydrides alone, Alternatively, it refers to a polyolefin that is partially or completely modified by adding an appropriate combination, and the manufacturing method thereof is not particularly limited, and any known method such as a melting method or a solution method can be applied. Unsaturated carboxylic acid or its anhydride is 0.001~ for crystalline polypropylene
The content is 15%, preferably 0.005 to 10%. Moreover, unmodified crystalline polypropylene means the above-mentioned polymer or copolymer that is not subjected to such modification treatment. Next, in the present invention, an ethylene homopolymer or an ethylene-vinyl acetate copolymer is used as the component (B). As for the ethylene homopolymer, any of low density, medium density and high density polymers can be used. Regarding the blending ratio of both components (A) and (B) above, 1 to 60 parts by weight of component (B) to 99 to 40 parts by weight of component (A), preferably 97 to 60 parts by weight of component (A). On the other hand, (B) component 3~
Should be 40 parts by weight. If the amount of component (B) is outside this range, the interlayer adhesive strength of the resulting laminate will not be satisfactory. Further, both of the above components are melted and kneaded in advance to form a composition. On the other hand, metals include aluminum, iron, galvanized iron, tinplate, copper, etc., and these may be in the form of unprocessed plates or processed products such as aluminum foil. The resin-metal laminate of the present invention does not require the use of an adhesive or the like during lamination, and when the metal is a plate-like body and the resin is a film or sheet, the two or more layers can be laminated into two or more layers. Just heat and press it. Further, when the metal is in the form of a plate or other processed product, the resin layer can be laminated onto the metal layer by applying powder coating, solution coating, or emulsion coating. The resin-metal laminate of the present invention obtained in this manner has high adhesive strength between the two, and also has solvent resistance and
Excellent heat resistance. Therefore, it can be effectively used as packaging materials for various foods, beverage cans, industrial materials, building materials, etc. Next, the present invention will be explained in detail with reference to examples. Production example 1 Production of modified polypropylene A Polypropylene (propylene/ethylene random copolymer, ethylene content 3% by weight, MI:
7 g/10 min, density 0.91 g/cm 3 ), 100 parts by weight of maleic anhydride, 5 parts by weight of terminal hydroxylated 1,4-polybutadiene (number average molecular weight 3000), and 2 parts by weight of dicumyl peroxide in xylene.
The mixture was added to 600 parts by weight, stirred and dissolved at 120°C for 60 minutes, and reacted at 140°C for 90 minutes with stirring.
Next, the reaction product was poured into a large amount of acetone, and the reaction product was precipitated and dried to obtain maleic anhydride-modified polypropylene in the form of a white powder. The amount of maleic anhydride added was 6.7% by weight (acid value measurement method). Production Example 2 Production of modified polypropylene B Polypropylene (propylene-ethylene random copolymer, ethylene content 3% by weight, MI:
7g/10min, density 0.91g/ cm3 ) 100 parts by weight, maleic anhydride 10 parts by weight and dicumyl peroxide 2
Parts by weight were added to 600 parts by weight of xylene, stirred and dissolved at 120°C for 60 minutes, and reacted at 140°C for 90 minutes with stirring. Next, the reaction product was poured into a large amount of acetone, and the reaction product was precipitated and dried to obtain a white powdery maleic anhydride-modified polymaropyrene. The amount of maleic anhydride added was 0.6% by weight (acid value measurement method). Example 1 The compositions of modified polypropylene A, unmodified polypropylene and low density polyethylene obtained in Production Example 1 were varied as shown in Table 1, and pellets were obtained by melt extrusion at 190°C using an extruder. This pellet was compression molded at 190°C to form a sheet approximately 300μ thick. This sheet and an 80 μm thick aluminum plate were laminated and heat-pressed at a temperature of 220° C. and a pressure of 1 kg for 1 second to obtain a resin-metal laminate. Table 1 shows the T peel strength of this laminate.

に示す。[Table] Although it is effective to add rubber substances such as ethylene/propylene rubber to improve adhesive strength, it is limited because the addition of such rubber substances reduces other physical properties such as solvent resistance. Generally undesirable, except when used for specific purposes. Comparative Examples 2 to 6 Except for using resins with the compositions shown in Table 3,
A resin-metal laminate was obtained in accordance with Example 1. The results of the T-peel strength and solvent resistance test (peel strength after immersion in gasoline for 24 hours and the state at that time) of this laminate are shown in Table 3 along with the results of Example 4.
