Novel sound-insulation self-leveling material as well as preparation method and application thereof

Abstract

The invention provides a novel sound-insulation self-leveling material and a preparation method thereof. The novel sound-insulation self-leveling material and the preparation method thereof aim to keep the surface smoothness of an existing floating floor, improve the capacity of ameliorating impact sound and noise and solve the problems that the overall thickness is large, the indoor comfort levelis influenced, and the manufacturing cost is high due to the fact that the structure of the floating floor is complex. According to the novel sound-insulation self-leveling material and the preparation method thereof, a pure benzene emulsion, a surfactant and hollow glass microspheres are mixed in quartz sand, so that the hollow glass microspheres are uniformly mixed in a mixture of the quartz sand and the like, a sound insulation material similar to closed-hole high-density polyethylene is formed, meanwhile, the surfaces of the hollow glass microspheres are smooth, so that the fluidity of the hollow glass microspheres on the whole novel sound-insulation self-leveling material is good, and therefore the novel sound-insulation self-leveling material can be used for replacing the effect ofa traditional sound insulation pad in the whole floating floor, the structure is simplified, the living comfort level is improved, and the cost is lowered.

Description

technical field [0001] The invention relates to the field of building materials and construction thereof, and more specifically relates to a novel sound-insulating self-leveling material and a preparation method thereof. Background technique [0002] Sound insulation is an important environmental protection measure in modern buildings. Construction noise includes impact sound and airborne sound, and most of the noise transmitted through the floor is impact sound. The impact sound of buildings is mainly the noise generated by the collision between objects and building structures, which propagates along the building structure and radiates into the surrounding air. In general buildings, the floor is the main building structure that generates impact noise. For example, the collision of door and window switches, objects falling on the ground, dragging of tables and chairs, children playing, and the knocking of heels when people walk on the floor will all produce impact noise. ....

Problems solved by technology

[0005] In view of this, in order to maintain the ability of the existing floating floor to improve the impact noise, and at the same time improve the complex structure of the floating floor, resulting in high overall thickness, affecting indoor comfort and high cost, this paper The invention proposes a new type of sound-proof self-leveling material and its preparation method. It mainly mixes pure benzene emulsion, surfactant and hollow glass microspheres into the quartz sand, so that the hollow glass microspheres are evenly mixed in the quartz sand and other mixtures to form Similar to sound insulation materials such as closed-cell high-density polyethylene, and because the surface of hollow glass microspheres is smooth, it has better fluidity in the whole new sound insulation self-leveling material, so it can be replaced by this new sound insulation self-leveling material The role of traditional sound insulation pads in the entire floating floor simplifies the structure, increases living comfort and reduces costs
