Abstract

The invention relates to the field of preparation of sealants and provides a high-hardness scratch-proof and fingerprint-resistant sealant on a metal surface. Raw materials of the sealant at least comprise a water-based resin, water-borne silicone oil, fatty alcohol polyether, an alkali reagent and a solvent. The invention furthermore provides a preparation method and a using method of the sealant.

Description

technical field [0001] The present invention relates to the field of preparation of sealing agents, in particular to a high-hardness, scratch-resistant and fingerprint-resistant sealing agent on metal surfaces and its preparation and use methods. Background technique [0002] Hot-dip metal materials, including hot-dip galvanized metal materials and hot-dip galvanized metal materials, in order to prevent corrosion, a layer of anti-rust sealant will be coated on the surface of the hot-dip metal materials to form a protective film. Magnesium alloy has good light weight, machinability, corrosion resistance, shock absorption, dimensional stability and impact resistance, far superior to other materials. These characteristics make magnesium alloys have applications in a wide range of fields, such as transportation, electronic industry, medical field, military industry, etc., and this trend will only increase. Especially in 3C products (Computer, Consumer Electronic Product, Commun...
