Benefits of technology

This patented technology relates to making coatings with improved properties by combining certain materials together or adding them specifically for specific purposes like reducing volatile organic compounds (VOC) emissions, increasing rapidity at drier temperatures, prevention against corrosions, resistant to rustiness, strengthen durability, improve flexibility, increase adhesiveness between different substrate surfaces, reduce damage caused during handling, protect from external factors such as rainwater, snow, ice, heat waves, sunlight, bending moment, pressure changes over time, and other environmental hazards associated therewith.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the efficiency or effectiveness of applying an antirust painting solution onto different materials without causing any issues like poor adhesion between them due to moisture evaporation during winter months when temperatures fall below freezing (F). Additionally, adding certain chemical substances may affect its ability to form films quickly while maintaining good barrier properties against corrosive elements.

Abstract

The invention discloses a waterborne quick-drying anticorrosive primer for a high-speed rail train body. The waterborne quick-drying anticorrosive primer is prepared from the following raw materials in parts by weight: 5 to 15 parts of waterborne methacrylic acid epoxy resin, 5 to 15 parts of waterborne acrylic resin, 3 to 5 parts of chitosan, 6 to 20 parts of anticorrosive pigment, 15 to 25 parts of talcum powder, 0.1 to 0.5 part of cationic FM emulsifier, 0.1 to 0.5 part of sodium polycarboxylic acid dispersant, 1 to 2 parts of sodium nitrite, 0.1 to 0.5 part of waterborne acrylic dryer, 0.1 to 0.5 part of pH (potential of hydrogen) value adjuster, and 20 to 40 parts of deionized water. The waterborne quick-drying anticorrosive primer has the advantages that the emission amount of VOC (volatile organic compound) is low, the drying speed is high, the anticorrosive and antirust properties are good, the mechanical property is high, the acid-resistant, alkaline-resistant and salt mist-resistant properties are realized, the anti-impact property is good, and the like; the waterborne quick-drying anticorrosive primer can be applied to the long-term protection of multiple types of products requiring high-quality coating property.
