Anchor hook type composite anti-corrosion metal component and preparation process

Abstract

The invention relates to metal surface anticorrosion, and discloses an anchor hook type composite anticorrosive metal member and a making technology thereof. The anticorrosive metal member comprises a metal substrate (2), a metal substrate anchor hook layer (1), an occlusion layer (3) and an anticorrosive layer (4), the metal substrate anchor hook layer (1) comprises flat-headed anchor hooks (11), the metal substrate anchor hook layer (1) has an embedded anchoring connection with the occlusion layer (3), and the anticorrosive layer (4) is arranged outside the occlusion layer (3). The making technology comprises the following steps: 1, making anchor grains having a roughness of 150-1500mum on the surface of the metal substrate; 2, pressing the anchor grains of the metal substrate to form the metal substrate anchor hook layer; and 3, coating to form the occlusion layer. In the invention, the high-roughness anchor hook type anchor grains are made on the base surface, an organic material of polar molecules or a Zn-Al anticorrosive metal binding layer is adopted to make the anchor hook type composite layer, and the composite layer has the characteristics of high adhesion, low energy consumption, high cost performance and long-acting anticorrosion.

Description

technical field [0001] The invention relates to metal surface anti-corrosion and long-acting heavy-duty anti-corrosion, in particular to an anchor hook type composite anti-corrosion metal component and a preparation process. Background technique [0002] Anti-corrosion metal is used as the coating layer. Due to the oxidation and electrochemical characteristics of metal, it still cannot meet the requirements in some specific environments. The coating of inorganic materials is the best anti-corrosion method. However, the brittleness, refractory and non-polar characteristics of inorganic materials are difficult to be used for coating. Inorganic fiber materials such as glass fiber and boron fiber have good anti-corrosion performance and cost performance, but it is difficult to directly paint or compound them on the metal surface. Contents of the invention [0003] The present invention aims at the shortcomings of inorganic fiber materials such as glass fiber and boron fiber i...
