Problems solved by technology

Due to the high price of foreign imported products, they are unfavorable in many aspects such as supply of goods, after-sales service, and construction adaptability; urban rail subway vehicles are passenger vehicles, and most of them run underground, so their coatings are required to be flame-retardant and heat-resistant , Low toxicity and environmental protection, in special cases, in order to facilitate the escape of the crowd, the flame retardant grade of the existing flame retardant coatings cannot meet the requirements

Abstract

The invention relates to a waterborne damping coating for metro vehicles and a preparation method of the waterborne damping coating for the metro vehicles. The waterborne damping coating for the metro vehicles is prepared according to a waterborne paint production process which includes the step of subjecting a special ternary blend emulsion, auxiliaries, functional pigments / fillers, composite flame retardant and water to soaking for pre-dispersion, high-speed dispersion, three-roll grinding, packaging and the like. The waterborne damping coating is a single-component coating and needed to be stirred completely before use, and an appropriate amount of water can be added for regulating applicable viscosity if the paint is too thick. The high-performance waterborne damping coating which is excellent in adhesion performance, high in composite damping loss factor and excellent in damping and denoising effect is widely applied to the metro vehicles to improve riding safety and comfort of the metro vehicles.

Description

technical field [0001] The invention relates to a water-based damping coating for subway vehicles and a preparation method thereof. Background technique [0002] With the rapid development of my country's rail transit industry, there is a large demand for subway vehicles at home and abroad. Due to the integration with international standards, the level of manufacturing technology for subway vehicles and the continuous improvement of people's requirements for environmental safety, it is proposed for urban rail / subway rolling stock manufacturers. Higher requirements require supporting use of environmentally friendly coatings with vibration and noise reduction, sound absorption and heat insulation, low smoke and low toxicity. Due to the high price of foreign imported products, they are unfavorable in many aspects such as supply, after-sales service, and construction adaptability; urban rail subway vehicles are passenger vehicles, and most of them run underground, so their coatin...
