Abstract

The invention discloses a waterborne quick-drying anticorrosive and rustproof paint for a high-speed rail chassis. The paint is prepared from the following raw materials: 5-15 parts of water-based methacrylic acid epoxy resin, 16-25 parts of water-based fluorosilicone resin, 3-5 parts of chitosan, 6-20 parts of a rustproof pigment, 15-25 parts of talcum powder, 0.1-0.5 part of a cationic FM emulsifier, 0.1-0.5 part of a polycarboxylic sodium salt dispersant, 1-2 parts of sodium nitrite, 0.1-0.5 part of a water-based acrylic drier, 0.1-0.5 part of a pH regulator, and 20-40 parts of deionized water. The primer provided by the invention has the advantages of low VOC emission, fast drying, good anticorrosion and rustproof performance, high mechanical properties, resistance to acid, alkali and salt fog, and good impact resistance, etc., and can be applied to long-term protection of various products needing high quality coating properties.

Description

technical field [0001] The invention belongs to the technical field of water-based coatings, in particular to a water-based quick-drying anti-corrosion and anti-rust coating for high-speed rail chassis. Background technique [0002] Practical applications show that water-based anti-corrosion paint can provide effective protection for various products such as steel under extreme conditions. Because water is their main solvent, water can also be used to clean and dilute water-based paints, they have almost no solvent taste, at the same time, the use of water-based paints can also bring lower costs to users, such as quick drying can save time, low fuel consumption Sexuality can reduce insurance costs, less indoor ventilation can reduce energy consumption, and the cost of solvents and cleaning agents is not required. Using a single-layer coating package can save downtime and the cost of erecting scaffolding. [0003] Due to the characteristics of water itself, one of the disadv...
