Problems solved by technology

The above-mentioned preparation process has the disadvantages of complicated preparation process and long time;
[0006] (2) Poor sound insulation performance: the sound insulation rate of gypsum-based sound-insulating walls is about 80%, so it still cannot meet market demand, and the sound-insulation rate of gypsum-based sound-insulating walls needs to be improved;
[0007] (3) The gypsum-based soundproof wall cannot degrade formaldehyde, which brings safety hazards to users

Abstract

The invention discloses light-weight sound-insulation high-elasticity cement gum. The cement gum comprises the following components by weight, 300-600 parts of a filler, 400-800 parts of sulfur-free odorless elastic thermoplastic rubber particles, 125-250 parts of a negative ion additive, 65-130 parts of hollow glass beads, 60-120 parts of redispersible latex powder, 30-60 parts of nanometer titanium dioxide, 3-6 parts of a retarder, 2-5 parts of a water-retaining agent, 3-6 parts of a water repellent and 400-800 parts of water. The light sound-insulation high-elasticity cement gum has the characteristics of high construction efficiency, low labor intensity, good sound insulation performance and high formaldehyde purification rate. In addition, the invention discloses a preparation methodof the light sound-insulation high-elasticity cement gum. The preparation method disclosed by the invention has the advantages of capability of promoting uniform mixing of all the components and accelerating dissolution of all the components, conservation of preparation time, simple preparation process and low operation requirements.

Description

technical field [0001] The invention relates to the field of mastic materials, more particularly, to a light-weight sound-insulating high-elasticity mastic and a preparation method thereof. Background technique [0002] With the rapid development of industry and rapid economic development, the world's demand for energy is also increasing. Among the increasing total energy consumption, building energy consumption is particularly large, accounting for about 11~25% of the total energy consumption. %, a lot of data and experiments have shown that the fastest and most effective way is to use thermal insulation and energy-saving materials. At the same time, with the development of transportation, urban construction, and the increase of population density, the increase of household facilities (audio, air conditioner, TV, etc.), the environmental noise is becoming more and more serious, and it has become a major public hazard that pollutes the human social environment. Most people ...
