Abstract

The invention discloses an epoxy resin anticorrosive coating comprising the following components in parts by weight: 100 parts of a waterborne epoxy emulsion, 20-30 parts of nano CeO2, 12-19 parts ofzinc phosphate, 15-18 parts of cellulose acetate butyrate, 4-8 parts of sodium polyacrylate, 3-5 parts of sodium silicate, 1-2 parts of a silane coupling agent, 3-6 parts of a curing agent, 2-5 partsof an antisettling agent, 1-2 parts of a plasticizer, 6-8 parts of an antifouling agent, 7-9 parts of a filler, 1-3 parts of a defoaming agent, 12-25 parts of phenolic resin, and 30-40 parts of water.The invention also discloses a preparation method of the epoxy resin anticorrosive coating. The epoxy resin anticorrosive coating has excellent anticorrosive performance, good film forming property and high adhesion force, and can provide effective anticorrosive protection for metals.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an epoxy resin anticorrosion coating and a preparation method thereof. Background technique [0002] The phenomenon of self-damage or deterioration caused by the chemical reaction or electrochemical reaction between metal and its surrounding environment is called corrosion, and the phenomenon of metal damage caused by physical, biological and mechanical factors is also collectively called corrosion. The mechanism of metal corrosion is mainly four types: physical corrosion, chemical corrosion, electrochemical corrosion and microbial corrosion. According to relevant statistics, the annual economic loss caused by metal corrosion in the world is about 6 times the sum of economic losses caused by natural disasters such as earthquakes, floods, and typhoons, which is a great economic waste. Metal corrosion not only brings huge economic losses to people, but also indirectly causes many accidents...
