Abstract

The invention relates to water-based industrial anticorrosion paint and a preparation method, which belong to a paint coating technology in the field of heavy corrosion protection. The anticorrosion paint comprises the following materials in parts by weight: 35-50 parts of water-based acrylic acid modified epoxide resin with the solid content of 48-50%, 6-15 parts of functional adjuvant, 30-50 parts of anti-rust pigment and 8-25 parts of deionized water. The preparation method of the water-based industrial anticorrosion paint comprises the steps of feeding the deionized water, the functional adjuvant, the water-based acrylic acid modified epoxide resin and the excluder pigment into a mixing tank in sequence, stirring at a speed controlled at 300-500rpm for 25-50min in a feeding process, and obtaining a finished product. Compared with the traditional solvent type paint, various resistance performances are improved significantly, and the water-based industrial anticorrosion paint particularly has the unique advantages of water resistance, no burning, no explosion, no harmful gas volatilization, no irritant smell, and the like. The water-based industrial anticorrosion paint is researched and developed specially for construction in high-temperature environments such as a metering plant and a pump station, and other high-danger and high-temperature painting tasks, has incomparable environmental friendliness, construction comfortability and safety, and is often used for anticorrosion protection and equipment maintenance in the field of the high-danger and high-temperature heavy corrosion protection.

Description

technical field [0001] The invention belongs to the paint coating technology in the field of heavy anticorrosion, and is particularly suitable for a water-based industrial anticorrosion paint and a preparation method for high-temperature working environments of high-risk enterprises such as petroleum and petrochemical enterprises. Background technique [0002] Traditional solvent-based coatings are flammable and explosive, and construction operations in high-risk and high-temperature environments have a high risk factor and potential safety hazards, resulting in inability to continue operations and difficult construction. Under the general environment of protecting ecology, saving energy and reducing emissions, and developing environmentally friendly coatings, water-based coatings with water-based resins as film-forming substances and water as dispersion medium and diluent have become a powerful product in the field of heavy-duty anti-corrosion. It is different from tradition...
