Problems solved by technology

Especially for the high-temperature and high-humidity environment in southern my country and Southeast Asia, especially in the subway tunnel environment, in addition to the good damping performance of the damping coating in the high-temperature and high-humidity environment, it is also required to have durable mildew resistance to avoid coating film Water absorption and mildew will seriously cause the coating to fall off and the damping performance to decrease
[0003] At present, the damping coatings on the market are difficult to meet the use requirements in this special environment, which limits its use in my country's subways

Abstract

The invention relates to the technical field of damping coatings, and provides a water-based damping coating, and a preparation method and application thereof. The water-based damping coating comprises a water-based emulsion and an anti-corrosion and anti-mildew agent, wherein the anti-corrosion and anti-mildew agent comprises one or two selected from organic modified nano-silver and nanometer zinc oxide. According to the water-based damping coating disclosed by the invention, organic modified nano-silver and / or nanometer zinc oxide are / is used as the anti-corrosion and anti-mildew agent, so acoating layer has long-term anti-corrosion and anti-mildew properties and environment-friendly characteristics. A traditional anti-corrosion and anti-mildew agent is generally a liquid anti-corrosionand anti-mildew agent which is easy to migrate in a humid environment during usage, and the problems of mould prevention performance loss and pollution are caused; and the traditional anti-corrosionand anti-mildew agent is a toxic substance and easily causes pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of damping coatings, in particular to a water-based damping coating and its preparation method and application. Background technique [0002] In recent years, with the continuous acceleration of urbanization in our country, urban traffic problems have become increasingly prominent. In order to improve people's travel environment, the state has invested a lot of money in the construction of subway projects. Damping coatings are widely used to control the vibration and noise generated during the operation of subway vehicles, and water-based damping coatings are gradually applied to the vibration and noise control of subway vehicles and rails due to their advantages of safety, environmental protection and convenient construction. Especially for the high-temperature and high-humidity environment in southern my country and Southeast Asia, especially in the subway tunnel environment, in addition to the good dampi...
