Problems solved by technology

In the work of Xu Fu, it is necessary to pay attention to the air pollution caused by the solvent and thinner in the paint, which is harmful to the human body; at the same time, most of the solvent-based paint and the thinner used in the painting operation are flammable and explosive materials. The painting operation itself presents a fire and explosion hazard
The possible causes of fire and explosion are that the operation rules are not followed during electrostatic painting, and discharge sparks are easily generated; waste paint, paint mist, paint materials and solvent waste rags are not well kept, and they are easy to spontaneously ignite and ignite when they are piled up; electrical equipment Improper selection or use, or failure to repair in time after damage, insufficient explosion-proof level, etc.; lightning strike disasters during thunderstorm season

Abstract

The invention discloses elastic anticorrosive paint which is prepared from the following components in percentage by weight: 6-12% of a flexibilizer, 30-45% of polysiloxane, 25-55% of packing, 5-8% of a crosslinking agent, 10-18% of a diluent, 5-10% of an auxiliary, 1-5% of sodium pyrophosphate, 1-3% of sodium tripolyphosphate and 2-4% of polyacrylate resin. The invention further discloses a preparation method of the elastic anticorrosive paint. A product disclosed by the invention is strong in adhesive force and the binding force of a coating and a matrix is strong; and the paint is efficient and convenient and simple to construct, and the inorganic paint is self-cured at normal temperature, so that the high-efficiency construction can be ensured and the paint has excellent salt mist resistance and aging resistance. The coating is self-repaired and local scratch caused by external forces still can be protected. The coating is free from cutting and welding damages and the welding quality is not affected with the coating.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to an anti-corrosion coating, in particular to a preparation method of an elastic anti-corrosion coating. Background technique [0002] Anti-corrosion coatings have become an important new force in the field of coatings. Anti-corrosion coatings are playing an increasingly important role, and their development prospects are promising. However, traditional products are gradually improved and new products are continuously developed and released. To adapt to the new standards and requirements of the anti-corrosion market and the development of environmental protection regulations, we still need to be proactive and continue to innovate. According to the analysis of industry experts: the price of anti-corrosion coatings is rising obviously, which is related to marine coatings and marine development. In recent years, the country has been increasing investment in seven-tenths of the earth's o...
