Problems solved by technology

However, solvent-based asphalt coatings have many shortcomings and disadvantages. They contain a large amount of volatile organic solvents, which will cause great harm to the ecological environment and human health during production, transportation, storage and use. With the promulgation of policies, laws and regulations and the intensification of environmental protection supervision, processing, production and construction enterprises often limit or stop production due to non-compliance with fugitive emissions, causing many economic losses

Abstract

The invention discloses a one-component water-based asphalt paint for damping springs and a preparation method thereof. The asphalt paint comprises the following raw materials in parts by weight: 10-30 parts of water-based high polymer emulsion, 20-50 parts of modified asphalt emulsion , 0.1-0.3 parts of dispersant, 0.1-0.2 parts of wetting agent, 0.5-0.8 parts of defoamer, 1-5 parts of pigment, 2-10 parts of inorganic nano filler, 0.2-0.5 part of thickening rheology additive, medium Blending agent 0.6-1.5 parts, drier 0.5-1.2 parts, deionized water 20-55 parts. The product of the present invention uses water as a solvent, modified asphalt emulsion and water-based polymer emulsion as film-forming substances, which greatly reduces the content of volatile organic compounds. After film formation, the surface of the paint film is smooth, dense and tough, and has good storage stability. Good anti-sagging performance, suitable for dip coating construction process requirements; suitable for large-scale batch production, and the obtained products have stable performance and reliable quality.

Description

technical field [0001] The invention relates to a one-component water-based asphalt paint for damping springs and a preparation method thereof, belonging to the technical field of water-based paints. Background technique [0002] The damping spring is an important component of the underframe of the rail vehicle, which plays a key role in alleviating and reducing the vibration and impact caused by vehicle startup, acceleration and deceleration, and ensuring the smooth and safe operation of the vehicle. This part is in the complex and harsh operating environment such as humidity, high temperature and severe cold all the year round. The traditional protection method is to apply solvent-based asphalt paint, which can meet the requirements of use. However, solvent-based asphalt coatings have many shortcomings and disadvantages. They contain a large amount of volatile organic solvents, which will cause great harm to the ecological environment and human health during production, tr...
