Embodiment Construction
[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0015] figure 1 The coating preparation process flow provided by the embodiment of the present invention is shown. It mainly includes the following steps:
[0016] (1) Modification of silica
[0017] In this experiment, physical dispersion and chemical dispersion were combined. First, the nano-silica particles were ball-milled, and then the silica particles were modified by mixing vinyl tris(β-methoxyethoxy)silane and silica particles. properties to obtain modified silica particles.
[0018] (2) Configure mother liquor and solvent
[0019] Prepare a solvent with analytically pure n-butanol and...

The invention discloses a preparation method for an anti-corrosion coating. The preparation method comprises the following steps: ball-milling nanometer silicon dioxide grains; mixing vinyl tri-(beta-methoxy ethyoxyl) silane with silicon dioxide grains, so as to modify the silicon dioxide grains and obtain modified silicon dioxide grains; preparing a mother solution and a solvent; preparing an end-product mother solution : adding the silicon dioxide grains which are different in content and are ball-milled and modified into the prepared mother solution, effectively dispersing the silicon dioxide and ball-milling, thereby obtaining the end-product mother solution; preparing a curing agent; and preparing the coating: preparing the end-product mother solution and the prepared curing agent at a mass ratio of 2:1 into the coating, standing by the prepared sample coating for one hour and curing, and then spreading, drying a spread sample under a heat-insulating condition, and then standing by. A dispersing agent adopted by the coating provided by the invention is a material in common use; the technology is simple and is easy to implement; the cost is low; and a single layer of the prepared coating can resist neutral salt fog for more than 360 hours.
