Abstract
The utility model provides a multilayer corrosion-resistant stainless steel wire, which comprises a wire core, an intermediate plating layer and a passivation protective film; the middle plating layer is positioned on the excircle of the wire core and is fixedly connected with the wire core; the passivation protective film is positioned on the excircle of the middle coating and is fixedly connected with the middle coating. The utility model provides a pair of anticorrosive stainless steel wire of multilayer utilizes the nickel coating on the excircle of sinle silk, improves the cohesion of skin and sinle silk, reduces stress, and outer chromium-plated layer can oxidize when the passivation simultaneously and form fine and close chromium oxide, and the protection wire rod just can reduce or need not high-order chromium ion in the passivation liquid, improves environmental protection.
Description
Technical Field
The utility model relates to an anticorrosive stainless steel wire rod of multilayer.
Background
The traditional stainless steel wire rod needs to be electroplated after being processed, so that the corrosion resistance and high temperature resistance of the wire rod are ensured, but the electroplating itself belongs to chemical reaction, so that the execution of the electroplating process is particularly strict, surface flash points are easily caused, and the quality of the wire rod is influenced.
Therefore, the existing process is improved to a passivation process, a passivation film is directly produced on the surface of the wire rod for protection, and the inner layer of the passivation film consists of chromium oxide, so that the wire rod has limited binding force with the wire core, is easy to damage under stress and cannot be effectively protected for a long time.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an anticorrosive stainless steel wire of multilayer utilizes middle cladding material to combine passive film and sinle silk, and cladding material divide into inlayer and skin again simultaneously, and the inlayer is convenient for combine the sinle silk, the outer passivation treating of being convenient for.
In order to solve the problem, the utility model provides a pair of anticorrosive stainless steel wire rod of multilayer has adopted following technical scheme:
a multilayer corrosion-resistant stainless steel wire comprises a wire core, an intermediate coating and a passivation protective film; the middle plating layer is positioned on the excircle of the wire core and is fixedly connected with the wire core; the passivation protective film is positioned on the excircle of the middle plating layer and is fixedly connected with the middle plating layer;
the middle plating layer comprises an inner layer and an outer layer, the inner layer is positioned on the outer circle of the wire core, and a nickel plating layer is adopted; the outer layer is positioned on the inner wall of the passivation protective film and adopts a chromium coating.
Furthermore, the passivation protective film is provided with two layers, wherein the inner side is a chromium oxide layer, and the outer side is an iron oxide layer.
Furthermore, the thickness of the middle plating layer is not more than 5 um.
Furthermore, the thickness of the nickel plating layer is larger than that of the chromium plating layer.
Further, the thickness of the chromium coating is not more than 1.5 um.
The beneficial effects of the utility model reside in that: the utility model provides a pair of anticorrosive stainless steel wire of multilayer utilizes the nickel coating on the excircle of sinle silk, improves the cohesion of skin and sinle silk, reduces stress, and outer chromium-plated layer can oxidize when the passivation simultaneously and form fine and close chromium oxide, and the protection wire rod just can reduce or need not high-order chromium ion in the passivation liquid, improves environmental protection.
