Abstract

The invention relates to an ether modifier-containing high-temperature and corrosion resisting functional coating and a preparation method thereof. The preparation method comprises the following steps: mixing a lithium silicate solution with the characteristics of non-toxicity, good high-temperature resistance and good film forming property with zinc powder being able to protect primary batteries, and adding certain amounts of solvents comprising silica gel and silicon acrylic emulsion and auxiliary assistants comprising alkylphenol polyethylene oxide ether and a silane coupling agent to prepare the high-temperature and corrosion resisting zinc-rich functional coating. The coating has the advantages of good high-temperature performances, simple technology, low cost and good use values.

Description

technical field [0001] The invention relates to a coating, in particular to a high-temperature-resistant zinc-rich coating for preventing metal corrosion and a preparation method thereof, belonging to the coating chemical industry field. Background technique [0002] Metal rusting is the most common form of corrosion. During corrosion, a chemical or electrochemical multiphase reaction occurs on the interface of the metal, which turns the metal into an oxidized (ion) state, which will significantly reduce the mechanical properties of the metal material such as strength, plasticity, and toughness, and destroy the geometry of the metal component. , increase the wear between parts, deteriorate the physical properties such as electricity and optics, shorten the service life of the equipment, and even cause catastrophic accidents such as fire and explosion. [0003] According to statistics, the steel that is directly lost due to corrosion each year accounts for about a quarter of...
