Epoxy resin modified protection coating

Abstract

An epoxy resin modified protection coating is prepared from, by mass, 60-90 parts of an epoxy resin polymer, 16-25 parts of acidic phosphate, 6-10 parts of pentaerythritol, 1-4 parts of cobalt naphthenate, 2-6 parts of titanium dioxide, 0.3-0.8 parts of a leveling agent and 15-25 parts of acetone. The coating is prepared through the following steps: fully crushing cobalt naphthenate and titanium dioxide, adding a mixed solution prepared from the epoxy resin polymer, the acidic phosphate, pentaerythritol and acetone, adding cobalt naphthenate, the titanium dioxide and the leveling agent, and carrying out high-speed homogenizing dispersion. The coating obtained in the invention has the advantages of optimized air drying performance after application, scientific formula, realization of good compactness and high flatness of a coating layer formed after anticorrosive coating is applied to a steel structure, improvement of the hardness of the coating layer, certain ultraviolet resistance, difficulty in destroy and local rust, prolongation of the service life of the coating layer, and wide application range.

Description

technical field [0001] The invention relates to a coating, in particular to an epoxy resin modified protective 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. [0003] For example, the Chinese patent authorizatio...
