Description of the Invention: [Technical Field to Which the Invention Is Alonged] TECHNICAL FIELD The present invention is directed to a type of composite material. BACKGROUND OF THE INVENTION In the past, in order to improve the financial record or bribery of the steel plate for automobiles, home appliances, building materials, etc., it is a gambling __ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In particular, after the salt treatment, the method of sealing by chromate has a great effect on improving the corrosion resistance or the coating, and is widely implemented. However, in the context of the problem of reducing the problem in the past year, there has been a tendency to develop a surface treatment technique that does not use a highly toxic complex, and has the following techniques. This technology provides a phosphoric acid-composite-treated steel sheet having an organic coating film of the second layer on the surface of the plated steel sheet having the i-th layer of the acid-filled coating layer (see, for example, Japan). Patent Publication No. 2〇〇1_1〇5528), and the above-mentioned Wei Xie treatment of Lai Ling Wei Zibu, Yi shot of at least i species of adhesion amount of 0·2~2.5g/m2 'and the aforementioned organic film system to choose The organic resin is mainly composed of at least an ethylene resin, an epoxy resin, a methyl formate resin, and an acrylic resin. In addition, a galvanized coating is formed on the surface of the steel sheet, a disk of acid coating of 3.3g/m2 or more, an organic view of G·3~2g/m2, and a mixed body age of Wei, and The town/rhodium (mass ratio) is an organic composite galvanized steel sheet having a 〇15 or more and a mass of 2 or more (see, for example, Japanese Patent Laid-Open Publication No. 200M31763). 1279452, usually formed and pressed under pressure. Therefore, it is necessary to carry out the galvanized steel sheet which has been subjected to the treatment as described above without being coated, and is used after being directly degreased and washed or after being cracked. Both corrosive and corrosion resistance after coating. However, the combination of the zinc-coated film and the organic film in the Wei-Jie-treated steel sheet and the organic composite zinc-coated steel sheet obtained by the method described above is not strong in the mixed environment, and the rate is extremely high. In the case of Wei towel, Wei Zinc film and Qianpiguan will produce "sweeping," and the lack of tolerance of money amount occurs. SUMMARY OF THE INVENTION 3 SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide an inorganic inorganic composite treated plated steel sheet which does not contain harmful chromate in the treated film and which can provide excellent corrosion resistance. The present inventors have specifically targeted the zinc-bonded zinc-containing zinc oxide film and the organic film by the inorganic-organic composite treatment of the forged steel plate, and reviewed various methods for improving the combination of the acid-filled skin film and the organic film in a corrosive environment. The state of the galvanized layer of the underlying layer of the zinc film is greatly affected, and the present invention has been completed. The invention provides a galvanized steel sheet which is treated by an inorganic organic composite treatment, wherein the galvanized steel sheet which has been subjected to an inorganic organic composite treatment is a galvanized layer having a (002) plane orientation of 50% or more on a steel sheet, and The galvanized layer has a zinc phosphate film containing magnesium and an organic film layer on the zinc phosphate film. The magnesium/phosphorus (mass ratio) in the zinc phosphate coating film is 0.1 or more, and the amount of the alloy is 20 mg/m2. Further, the organic film layer contains an epoxy resin and/or a denatured epoxy resin, and the adhesion amount of the organic film layer is 0.3 to 5 g/m2. 1279452 The above-mentioned inorganic-organic composite-treated plated steel plate of the present invention can obtain a job-like slogan because of the absence of chromate, and the slave-making method is also attacked, and the cost is also low, so that it can be used in automobiles, home appliances, Jiancai for various purposes. [-PC] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail. The inorganic core composite treatment of the present invention is __form_layer, (4) electroplating and hot dip plating methods, but the crystal orientation of the (002) plane is required to be 50% or more. Wherein, the so-called "crystal orientation" refers to the intensity of each peak of the zinc crystals by the X-ray winding device and then the sum of the peak intensities divided by the percentage of the peak intensity of the surface of the (8) surface. The amount of riding is limited and the scale is determined. The higher corrosion resistance of the county is better than 20g/m2. The orientation of the crystal of the (002) plane is limited to 5〇% or more because it is not full of lions. Poor. The reason why 50% of the shaft can get good corrosion resistance is not very clear. ^ It can be assumed that one of the reasons is that the traits formed on the electric ore layer as in the aforementioned state will change. The adhesion of the upper organic film layer is good and the other is a good reason. It is conceivable that even if there is no coating of the acid film, the exposed portion of the galvanized layer exists, and The layer structure 'is good for the adhesion between the electric display and the organic layer of the upper layer. To make the crystal of the _)® (10) substantiate, the material can be plated under the condition that the potential is low. Wei said the concentration, current density and other controls. By making the concentration of zinc ions in the electric clock bath high, or making the current density of the electric ore low, the orientation of (002) plane can be raised. The zinc phosphate treated film can be formed from the conventionally known 279452 containing a phosphate ion and a zinc ion. The supply source of the citrate ion is not limited as long as it contains zinc. For example, it may be a supply source of zinc, an oxygen scale, a carbonated acid or a citrate ion, and may be a sodium or the like which contains a compound. It is not limited, for example, there may be mentioned Wei, pentoxide scale, Gu Dihydrogen, and the like. Before the butterfly. x, bribe, pure, copper, resistant 21 or dollar money. The touch can be more sturdy and the adhesion between the post-treated film and the post-treated film can be improved. Preferably, the ratio of the town to the phosphorus in the coating film of the zinc phosphate treated film is preferably O.m. Less than the call, may not be able to see _ add and improve the financial results. It is preferable that the amount of the film in the film of the phosphoric acid-treated film is 2 (10) or more. When it is less than 20 mg/m2, it may not improve the resistance to impurities. Further, it is preferable that the zinc phosphate-treated film is formed by a film thickness of 0.3 gW or an upper limit of 5 g/m 2 . Less than a3g/m&gt;, the resistance may be insufficient, and when it exceeds g/m, the film may peel off when subjected to intense processing. In the case of the treatment liquid for the phosphoric acid treatment film, a commercially available treatment liquid such as a metal ion other than a hetero ion or a resonating ion and, if necessary, a metal ion or a deionized fluoride ion may be used. In order to contain a town in the film of the linonic acid, it is preferable to add a bath such as a nitric surface to the zinc phosphate treatment liquid. The ratio of (four) lin/phosphorus in the film can be controlled by the amount of addition. By means of the phosphoric acid treatment, the plating method is used to form a zinc phosphate treatment, for example, by using a reactive treatment or a coated treatment towel, for example, it can be degreased on a galvanized steel sheet. After the secret, the surface is adjusted to I, so that the sputum and the w zinc sulphate are used, and Wei Xing secret, dry to 1279452 to form a zinc sulphate treatment surface. Bribe zinc treatment film treatment time or treatment agent concentration to adjust. The amount of film, for example, can be changed
