AI Technical Summary

Problems solved by technology

Hollow floors and long-haired soft carpets are expensive and relatively expensive; the sound-insulating mortar coating is thicker, which not only occupies the height of the floor but also has a general sound-insulating effect; although the sound-insulating effect of the sound-insulating pad is good, it requires high construction technology. The process is more complicated and the overall cost is more expensive
In addition, the sound insulation materials currently on the market have problems such as poor sound insulation performance, easy to deteriorate, easy to break, high material cost, etc., and may contain toxic or unenvironmentally friendly chemical additives. Although they claim to meet GB50118- In 2010, the requirements for ordinary residents were met, but the requirements for sound insulation performance of high-demand residents were not met

Abstract

A novel sound insulation material comprises a main coating and a sealing layer, and each of main coating and the sealing layer comprises powder and liquid. The mass ratio of powder to liquid in the main coating is (2-6): 1; and the mass ratio of the powder material to the liquid material in the sealing layer is 1: (2-5). The main coating prepared by the invention is a sound wave absorbing coating and has very strong sound wave damping capacity; and the sealing layer plays a role in protecting the main coating, can prevent cement mortar on the sealing layer from leaking and entering the main coating to affect the sound insulation performance of the system, and also has a sound wave damping effect. The main coating and the sealing layer prepared from the sound insulation material have multiple porous structures and are arranged in the propagation path of sound waves, and the purpose of sound insulation is achieved by absorbing the energy of the sound waves. Compared with other sound insulation materials in the market, the material provided by the invention has better sound insulation performance under the condition of the same coating thickness. The invention also relates to a preparation method and application of the novel sound insulation material.

Description

technical field [0001] The invention belongs to the technical field of building sound insulation, and in particular relates to a novel sound insulation material, a preparation method and an application thereof. Background technique [0002] With the development of society and the improvement of people's quality of life, the health problems caused by noise pollution have gradually received more and more attention. It is listed as the world's three major pollution along with air pollution and water pollution. At present, there are a large number of high-rise buildings in the society, including civil buildings, office buildings, shopping malls, etc. In addition to requiring the coatings used in the buildings to meet the requirements of green and healthy, the requirements for sound insulation are also getting higher and higher, especially between the interlayers. When objects collide or rub against each other, they will cause noise pollution through the formation of direct sound...
