Problems solved by technology

[0003] 1. The hollow vitrified microspheres in the sound-proof coating only have the effect of sound-absorbing and noise-proof, and the floors will vibrate under the influence of sound waves, so noise pollution will still occur, and the sound-proof effect is not good;
[0004] 2. The coating prepared by using hollow vitrified microspheres alone as a filler has good reflective performance, but its thermal insulation effect is poor, resulting in poor heat insulation of this reflective coating

Abstract

The invention relates to the technical field of flame-retardant and sound-insulating coatings, in particular to a flame-retardant and sound-insulating coating, which comprises, by mass, 14-20% of a silicone acrylic emulsion, 12.25-22.6% of deionized water, 0.1-0.25% of cellulose, 0.45-0.5% of wood fibers, 0.2-0.4% of a wetting dispersant, 0.15-0.2% of an anti-corrosion and bactericidal agent, 0.8-1.2% of a flame retardant, 12-14% of mica powder, 14-16% of aluminum hydroxide, 7-13% of glass bead mixed particles, 9-12% of rubber powder, 0.25-0.35% of PP fibers, 7-12% of a thermal insulation auxiliary agent, and 8-15% of a damping and buffering agent. The damping and buffering agent comprises floating beads and stone-free mineral wool, so that the coating can absorb noise and has good sound insulation and noise reduction functions. Moreover, the floating beads are hollow balls, thin-walled and hollow and good in damping effect, and are matched with the stone-free mineral wool and the mica powder for use, so that the formed coating layer has excellent damping and buffering effects, noise pollution caused by vibration can be further reduced, and the sound insulation and damping coating has double noise reduction effects.

Description

technical field [0001] The invention relates to the technical field of flame-retardant and sound-insulating coatings, in particular to a flame-retardant and sound-insulating coating and a preparation method thereof. Background technique [0002] With the development of society, the noise pollution in the city is also increasing, and it is getting bigger and bigger. Especially in commercial housing, due to the low density between buildings and the close connection between floors, often small sounds or vibrations will become serious noise pollution. Therefore, in the construction process of buildings, people use various sound insulation coatings , The sound insulation coating contains hollow vitrified microspheres, the main component of which is sodium borosilicate, which has small thermal conductivity, low true density, high and low temperature resistance, good thermal stability, sound absorption, fire prevention, and flame retardant Advantages such as, but, the sound insula...
