Abstract

A polyphenylene sulfide modified coating is characterized in that the polyphenylene sulfide modified coating is made of raw materials in parts by mass, 60-90 parts of polyphenylene sulfide polymer, 16-25 parts of acid phosphate, 6-10 parts of pentaerythritol, 1-4 parts of cobaltous naphthenate, 2-6 parts of titanium dioxide, 0.3-0.8 part of a levelling agent, and 15-25 parts of acrylic acid. The cobaltous naphthenate and the titanium dioxide are fully crushed and added to a mixture liquid made of the polyphenylene sulfide polymer, the acid phosphate, the pentaerythritol and the acrylic acid. Then high-speed homogeneous dispersion is performed after the cobaltous naphthenate, the titanium dioxide, and the levelling agent are added. The air seasoning performance after the coating is painted is optimized. The formula is reasonable. Coating layers are dense and the flatness is high after the anticorrosion painting is carried out on steel structures. The hardness of the coating layers is improved too, and the coating layers have good high temperature resistant and rust resistant capacities. The damage and local rust do not appear easily. The service life of the coating layers is prolonged, and the use range is wide.

Description

technical field [0001] The invention relates to a coating, in particular to a polyphenylene sulfide modified coating, which belongs to the technical field of protective coatings. 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 UV resistance, and are prone to damage and local corrosion after a long time , affecting the service life of the steel structure itself.
