Abstract

The invention discloses a coating material for construction in the existence of water and rust and a preparation method of the coating material. The coating material comprises a component A and a component B which are in the weight ratio of (7-10):1, wherein the component A comprises the raw materials in percentage by weight: 50-60 percent of epoxy resin with ultra-low molecular weight, 5-10 percent of organic silicon resin, 5-10 percent of water-based phosphate chelate, 5-10 percent of barium sulfate, 5-10 percent of talcum powder, 5-10 percent of silicon carbide, 1-1.5 percent of silicone resin and 0.1-0.5 percent of organic silicon defoaming agent. The coating material has the characteristics of convenience and rapidness in construction, long service life, and can be coated on a steel structure in the sea in the existence of water, rust and dirt, realizes long-lasting anti-corrosion effect and thick coating, and effectively overcomes the technical difficulty in anti-corrosion operation of the steel structure under a severe environment of a splash zone. Furthermore, the invention also provides the preparation method of the coating material.

Description

technical field [0001] The invention relates to the technical field of coating materials, in particular to a coating material for construction with water and rust and a preparation method thereof. Background technique [0002] According to statistics, the annual loss caused by corrosion in the world accounts for 2%-4% of the gross national economic product, which is greater than the sum of losses caused by natural disasters such as fire, wind, flood and earthquake. The country attaches great importance to marine corrosion and protection research. my country is a large ocean country, with a coastline of more than 18,000 kilometers and a sea area of ​​more than 3 million km2 under its jurisdiction. Marine corrosion and protection are one of the key issues that need to be seriously resolved in my country's economic development. In terms of anti-corrosion of marine steel structures, the corrosion environment is different, and the anti-corrosion measures adopted are different. ...
