The present invention relates to a metal-plastic composite material, in which an organosol-dispersed adhesive layer of maleic anhydride-modified polypropylene is coated on both sides of a polypropylene and elastomer blend synthetic resin film 1 filled with titanate-treated calcium carbonate powder. This relates to a metal-plastic composite material characterized in that it is formed by adhesively laminating metal plates 3, 3 through each other. Metal-plastic composites, which are made by sandwiching and laminating polypropylene films between thin metal plates, have been provided as materials for automobiles, construction materials, etc. However, this requires high adhesion between the polypropylene film and the metal plate, as well as high impact strength and heat resistance in the polypropylene film, but conventional products have not been able to fully satisfy these requirements. . The present invention has been made in view of the above points, and it is an object of the present invention to provide a metal-plastic composite material that can satisfy the above properties. The present invention will be explained in detail below. The synthetic resin film 1 used in the present invention can be obtained by forming a mixed resin of polypropylene and an elastomer into a film with a thickness of about 0.05 to 1.0 mm, and further, titanate-treated calcium carbonate powder is blended into the synthetic resin film 1. It has been filled. Calcium carbonate powder is mixed as a filler in order to improve the heat resistance properties of polypropylene, such as its stiffness and heat deflection.
It is preferable to mix 70% by weight. Here, calcium carbonate is subjected to titanate treatment, making it possible to add a large amount of calcium carbonate. In other words, the titanium-based coupling agent added in the titanate treatment increases the affinity between calcium carbonate and resin, improves the wettability of calcium carbonate to the resin, and increases the amount of calcium carbonate added. Titanium-based coupling agents for calcium include, for example, isopropyl triisotearoyl titanate.

優れていることが確認された。[Formula] and isopropyl tridodecylbenzenesulfonyl titanate can be used. In addition, polypropylene generally lacks impact resistance, and especially when calcium carbonate is added as described above, the impact resistance is further reduced. Therefore, in the present invention, by blending polypropylene with an elastomer, the impact resistance of polypropylene is improved, resulting in a synthetic resin film 1 with excellent impact resistance.
It was designed so that it could be obtained. Here, as the elastomer, one that is rubber-like and has an elongation at break of 200% or more, such as ethylene-propylene rubber, ethylene-propylene-diene rubber, and ethylene-butadiene plastomer, can be used. The blending amount is 50~50% polypropylene.
It is preferable to set the amount of the elastomer to 75% by weight and the elastomer to be in the range of 25 to 50% by weight. In other words, elastomer
If the elastomer is added in an amount of 25% by weight or more, the impact strength increases rapidly, if it is less than 25% by weight, it is not possible to obtain a satisfactory impact resistance, and even if the elastomer is added in an amount of 50% by weight or more, the impact strength increases rapidly. Impact resistance cannot be improved. Synthetic resin film 1 formed as above
Metal plates 3, 3 having plating layers 4, 4 applied on both sides are adhered to the upper and lower surfaces of the metal plate 3. As the metal plate 3, a galvanized steel plate, a chrome-plated steel plate, an aluminum-zinc alloy plated steel plate, etc. can be used, and the adhesive layer 2 between the synthetic resin film 1 and the metal plates 3, 3
As the adhesive, an organosol dispersion adhesive of maleic anhydride-modified polypropylene is used. This organosol-dispersed adhesive made of maleic anhydride-modified polypropylene has excellent adhesiveness between the synthetic resin film 1 containing polypropylene as a main component and the metal plate 3. In this way, a metal-plastic composite as shown in the figure can be obtained. As described above, according to the present invention, the thermal properties of a synthetic resin film can be improved by filling with calcium carbonate powder, and the decrease in impact resistance of the synthetic resin film due to the addition of calcium carbonate powder can be prevented by adding the calcium carbonate powder to the elastomer. As a result, both the impact resistance and thermal properties of the synthetic resin film can be improved.Moreover, the adhesive layer is an organosol-dispersed adhesive layer of maleic anhydride-modified polypropylene. By this method, a synthetic resin film and a metal plate can be firmly laminated and bonded. Furthermore, since the calcium carbonate powder is titanate-treated, it increases the affinity between calcium carbonate and resin, making it possible to fill a large amount of calcium carbonate.In addition to improving thermal properties, calcium carbonate also increases the amount of calcium carbonate. It is possible to obtain products at low cost with great effects. Next, the present invention will be specifically explained using examples. <Example> A galvanized steel plate with a thickness of 0.2 mm was degreased and chemically treated, and an organosol dispersed adhesive of maleic anhydride-modified polypropylene (Morton Chemical Co., Ltd.'s Moaglyme 78HB71) was applied to one side of the steel plate at a dry weight of 1.6 mm.
The coating was applied at a concentration of ~2.0 g/m 2 , and then passed through a baking furnace and baked at a plate temperature of 205°C. On the other hand, 50% by weight of calcium carbonate powder titanated using isopropyl triisostearoyl titanate was mixed with a resin blended with 70% by weight of polypropylene and 30% by weight of ethylene-propylene-diene-rubber, and this was made into a sheet with a thickness of
A 0.42 mm synthetic resin film was obtained. This synthetic resin film was preheated, and one side of the synthetic resin film was adhered by a roll press to the adhesive side of the steel piece that had just come out of the baking oven. Furthermore, a steel plate similar to that described above with an adhesive obtained in the same manner as above was adhered to the other surface of the synthetic resin film to obtain a metal-plastic composite material. When the metal-plastic composite thus obtained was subjected to a peel test between the synthetic resin film and the steel plate, a peel value of 12 to 23 kg/25 mm was obtained. For comparison, we conducted a peel test between a synthetic resin film and a steel plate using a conventionally used polypropylene-based adhesive, and found that it had a peeling test of 3 to 6.
Kg/25mm, and it was confirmed that the adhesive strength of the present invention was several times better.
