Problems solved by technology

At present, most of the sound insulation mat materials are soft and porous materials. In the coastal cities of our country, the concentration of salt spray is high. The sound insulation mat material is very easy to absorb salt mist, which will cause the sound insulation mat to be eroded, reduce the service life, and seriously affect the living environment of the majority of residents.

Abstract

The invention discloses an anticorrosive coating, a preparation method and applications thereof, wherein the anticorrosive coating is prepared by mixing a component A and a component B according to amass part ratio of 1:4, the component A is prepared by mixing the following raw materials in parts by mass: 15-25 parts of a polyisocyanate prepolymer, 0.05-0.1 part of a defoaming agent and 5-15 parts of propylene glycol diacetate, and the component B is prepared by mixing the following raw materials in parts by mass: 25-35 parts of a water-based resin A, 25-35 parts of a water-based resin B, 5-10 parts of deionized water, 0.2-2 parts of an antifoaming agent, 0.1-2 parts of a leveling agent, 0.2-2 parts of a dispersing agent, 30-40 parts of needle-like zinc oxide, 0.1-0.5 part of a rheological agent and 20-30 parts of high-entropy alloy powder. According to the invention, needle-like zinc oxide and nanometer high-entropy alloy particles with a single-body-centered cubic structure are added into a coating, so that the hardness and the corrosion resistance of the coating are improved; and by spraying a sound insulation pad or a ship with the anticorrosive coating of the invention, the corrosion rate is obviously reduced, and the antibacterial property is enhanced, so that the sound insulation pad or the ship has long service life.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion materials, and in particular relates to an anti-corrosion coating, a preparation method thereof and an application in anti-corrosion of sound-insulating mats in coastal areas or anti-corrosion of ships. Background technique [0002] The residential buildings in our country are many and high-rise buildings, and the impact noise interference of the upper and lower floors has always been a hot spot of neighborhood disputes, seriously affecting the living quality of the majority of residents. In order to solve this problem, the state has issued a series of regulations and policies to regulate the noise of buildings. Among them, in the "Code for Sound Insulation Design of Civil Buildings", the impact sound pressure level of the household floor in various buildings is stipulated: the weighted normalized impact sound pressure level (laboratory measurement) of the residential floor should be less t...
