Abstract

The invention discloses a preparation method of heavy anti-corrosion coating containing nano titanium, relates to a preparation method of heavy anti-corrosion coating added with nano titanium particles and particularly relates to a method of preparing heavy anti-corrosion coating by taking modified organic silicon resin as a matrix. The preparation method comprises the following steps: synthesizing low polymer organic silicon by phenyltriethoxysilane and dimethyldiethoxysilane, modifying by adopting epoxy resin E-20, and finally adding nano taitaium powder to uniformly stir, thereby preparing the heavy anti-corrosion coating containing nano titanium. According to the preparation method disclosed by the invention, firstly, the organic silicon resin is adopted as a film-forming agent, so that the heavy anti-corrosion coating has the advantages of being good in bonding strength, good in coating toughness, not prone to causing embrittlement, low in curing temperature, strong in corrosion resistance, and the like; secondly, the nano titanium particles are dispersed into the organic silicon resin, and the titanium is applied to the corrosion prevention field in the form of coating, so that not only can stainless steel be substituted to solve an industrial corrosion problem, but also the manufacturing cost can be greatly lowered.

Description

technical field [0001] The invention relates to a preparation method of a heavy-duty anti-corrosion paint added with nano-titanium particles, in particular to a method for preparing a heavy-duty anti-corrosion paint by using a modified silicone resin as a matrix. Background technique [0002] With the continuous deepening of marine development, emerging industries (such as seawater desalination, seawater utilization) and modern projects (such as the Three Gorges Hydropower Station) need for environmental tolerance and service life, people urgently need long-life anti-corrosion coatings. [0003] Titanium is a metal material with excellent corrosion resistance. It is non-toxic, light in specific gravity, and high in specific strength. Widely used in the field of technology. With the development of coating technology, titanium nano anticorrosion coatings have attracted people's attention because of their excellent performance. However, due to the high price of titanium metal...
