Highly dispersed epoxy resin modified coating

Abstract

A highly dispersed epoxy resin modified coating is characterized in that: the highly dispersed epoxy resin modified coating is prepared from 60-90 parts by mass of a polyphenylene sulfide polymer, 16-25 parts by mass of an acid phosphate, 6-10 parts by mass of pentaerythritol, 1-4 parts by mass of potassium tripolyphosphate, 2-6 parts by mass of zinc oxide, 0.3-0.8 part by mass of a leveling agent and 15-25 parts by mass of acetone as raw materials, the potassium tripolyphosphate and the zinc oxide are fully crushed and then added into a mixed solution of the polyphenylene sulfide polymer, the acid phosphate, the pentaerythritol and the acetone, then the potassium tripolyphosphate, the zinc oxide and the leveling agent are added for high-speed homogeneous dispersion. Air drying performance of the coating after brushing can be optimized, the formula is reasonable, when a steel structure is coated with the coating for anticorrosion, a coating layer is dense and high in flatness, the hardness of the coating layer is improved, and the dispersion property in the process of use is improved. After the steel structure is coated with the coating, the coating layer is even in color, breakage and local corrosion are not easy to occur, the service life of the coating layer is prolonged, and the use range is wide.

Description

technical field [0001] The invention relates to a paint, in particular to a highly dispersible epoxy resin modified paint, which belongs to the technical field of protective paint. Background technique [0002] At present, steel structures are more and more widely used in construction, machinery and other fields. Steel structures have the advantages of easy forming, mass production, and convenient installation. Steel structures can partially replace brick and concrete structures in the construction field. Large-scale factories also use steel structures. structure. Steel structures will rust in natural environments such as humidity, and need to be painted with anti-corrosion and anti-rust paints. However, the existing steel structure paints have simple formulas, short service life, poor dispersion performance during use, and easily lead to uneven color. After a long time, it is prone to breakage and local corrosion. Contents of the invention [0003] The purpose of the pr...
