Abstract
The invention relates to the technical field of strings, in particular to a fully-covered string based on a nano coating. The string includes a string body, a tin coating and the nano coating, the tin coating and the nano coating are arranged on the surface of the string body, the string body is high-carbon steel with a circular section, the carbon content of the high-carbon steel is 0.8% + / -0.99%, the outer surface of the string body is coated with the tin coating, the tin coating is formed by heating and mixing tin methanesulfonate, methanesulfonic acid and molybdenum dioxide in the volume size of 110:0.5:3, the surface side of the tin coating is uniformly coated with the nano coating, and the nano coating is a C4-structure fluoropolymer coating. The preparation process includes the following steps of S1, wire drawing, S2, cleaning and drying, S3, Tin coating and S4, nano layer coating. By coating the surface layer of a high-carbon steel wire sequentially with the tin coating layer and the nano coating layer, the high-carbon steel wire has the same concentricity and better corrosion resistance and stain resistance.
Description
technical field [0001] The invention relates to the technical field of strings, in particular to a whole film-coated string based on nano-coating and a preparation process thereof. Background technique [0002] Corrosion resistance of strings is a big aspect. There are many things to say. Corrosion resistance is necessary for the service life of strings. We rely on the adjustment of corrosion resistance to achieve different service life of strings. The corrosion resistance of the string is directly related to its coating layer. The existing coating layer of the string is easy to peel off and difficult to clean. At the same time, the coating is uneven, which seriously affects the pitch of the string. Therefore, we propose a nano-coating based Layer whole film-coated strings and its preparation process to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to solve the existing shortcoming that the existing string coating lay...
