Water-based sound insulation coating for ground sound insulation and shock absorption, and preparation method thereof

Abstract

The invention belongs to the technical field of coatings, and particularly relates to a water-based sound insulation coating for ground sound insulation and shock absorption, and a preparation methodthereof. The coating comprises an emulsion, a filler, aggregates, a halogen-free flame retardant, a defoaming agent, a bactericide, a thickening agent, a dispersing agent and deionized water, and further comprises rubber particles and rubber fibers. The coating of the invention has better flowability, film-forming property, sound insulation property, damping property and shock absorption propertythan coatings in the prior art, and is better than other sound insulation coatings with the same thickness; the sound insulation coating can achieve A1-level fire prevention, and has the advantages ofenvironmental friendliness, no pollution, good protecting effect on buildings, good adhesive force, good permeability, good compatibility with a base material, and no crack; the production technologyof the coating has the advantages of simplicity, easiness in implementation, improvement of the performances of the coating through reasonable dispersion and mixing of all the components, simplicityin construction operation, avoiding of node treatment with complex procedures, reduction of cross operation, reduction of the procedures of other traditional floor sound insulation methods by at least50%, and high cost performance.

Description

technical field [0001] This field belongs to the technical field of coatings, and in particular relates to a water-based sound-insulating coating for ground sound-insulating and shock-absorbing and a preparation method thereof. Background technique [0002] With the development of social economy and the improvement of people's quality of life, noise pollution has gradually attracted attention. It is listed as one of the three major pollutions in the world along with air pollution and water pollution. There are a large number of high-rise buildings emerging, including residential buildings, shopping malls and office buildings, etc., and in addition to the requirements for the coating of the building layer to meet the requirements of green health, the requirements for sound insulation and shock absorption are also increasing. high. Whether it is a compartment, a compartment or a room, when objects collide, they will cause noise pollution through the formed direct sound or ref...

AI Technical Summary

Problems solved by technology

[0003] Nowadays, two methods are commonly used for ground sound insulation: one is to lay hollow floors or lay long-haired soft carpets on the surface, which is expensive and relatively expensive; the other is to lay sound-proof mortar, sound-proof mat, and glass wool on the ground cushion. Materials with damping characteristics are used to achieve the effect of sound insulation. Damping materials are materials that convert solid mechanical vibration energy into heat energy and are mainly used for vibration and noise control. Damping coatings have been widely used in shock absorption and sound insulation. , Noise-reducing damping materials, damping materials can be divided into solvent-based damping materials and water-based damping materials, and traditional solvent-based damping materials contain a large amount of organic matter, which is easy to cause environmental pollution, and existing sound-proof coatings may contain toxic , non-environmentally friendly chemical additives, poor sound insulation performance, easy to deteriorate, easy to break, etc., or the use of coatings is relatively complicated, and the cost of materials is relatively high.
