き性が良好となることを見い出した。[Means for Solving the Problems] In view of the above-mentioned circumstances, the present inventors have repeatedly conducted various experiments, and as a result, the present inventors have found that the surface of the steel plate is coated with Zn alone or as a Zn alloy plating layer as a lower layer, and as an upper layer with specific dimensions. By forming a Zn alloy layer containing Zn alone or a Zn alloy layer containing shaped non-metallic fine particles alone or in combination within a predetermined amount, it has better external rust resistance and corrosion cracking resistance in processed parts than conventional alloy plated steel sheets. I found that.

。また、下層として、Ｚｎ単独もしくは、Ｚ １１合金
めっき層が存在することにより。This is thought to be because the non-metallic fine particles are non-conductive, exhibiting a kind of Kukorya effect and improving corrosion resistance. In addition, the presence of Zn alone or a Z 11 alloy plating layer as the lower layer.
加工性が向上することも判明した。It was also found that processability was improved.

Ｚｎ系複合めっき鋼板にある。The present invention has been made based on the above findings, and its gist is to have a Zn alone or Zr + alloy plating layer as a lower layer on one or both sides of steel, and an upper layer with an average grain size of 5 μm. A Zn-based composite plated steel sheet is characterized by having Zn alone or Zn alloy plating containing 0.01 to 30 wt % of the following non-metal fine particles alone or in combination.
以下、本発明の詳細な説明する。The present invention will be explained in detail below.

ら１０〜１５０ｇ／ｍ程度が望ましい。This refers to Zn-5n, Zn-Cd, etc., and the reason why these plating layers are used as the lower layer is because the coating film has good adhesion. Although the basis weight is not particularly determined, it is preferably about 10 to 150 g/m from the viewpoint of corrosion resistance.

ｉＮ、ＡＱＮ等の窒化物を用いることが出来る。From the viewpoint of the content or size and shape of nonmetal fine particles, which will be described later, a range of about 0.1 to 20 μm is effective. In the first aspect of the present invention, in which alloy plating systems are effective in improving paint film adhesion, the main point lies in the inclusion of non-metallic fine particles in the plating layer, either singly or in combination. In this case, the non-metal fine particles contained in the upper layer are colloidal Sin, 5in2, AM, ○, Fe, O, TiO coated with Go, Mg, etc.
, etc., carbides such as SiC, TiC, SiN, T
Nitride such as iN and AQN can be used.

を超えると加工性が悪くなる。In particular, the above-mentioned Sin, or Sin whose surface is coated with CO, Mg, etc., is effective in corrosion resistance and external rust resistance. In addition to these non-metallic particles, it goes without saying that fine particles of new materials that are currently being developed can also be used; however, the average particle size of the fine particles must be 5μ or less. In particular, a material with a diameter of about 2.0 mμ is most effective in both corrosion resistance and workability. If it exceeds 5μ, workability will deteriorate. Note that the average particle size means the particle size that has the largest distribution among all particles. Moreover, the content in the plating layer needs to be 0.01 to 30 wt%. If it is less than 0.01%, the corrosion resistance will not improve and 30%
If it exceeds this value, workability will deteriorate.
