Abstract

The invention discloses a sound insulation coating for a building floor and a preparation method of the sound insulation coating. The sound insulation coating for the building floor comprises the following components in percentage by weight: 8%-15% of an acrylic emulsion, 5%-7% of floating beads, 38%-45% of stone-free mineral wool, 3%-5% of mica powder, 1%-5% of butadiene-acrylonitrile rubber powder, 30%-35% of water and 1% of auxiliary materials, wherein the acrylic emulsion is a compound emulsion of an acrylic elastic emulsion and an acrylic styrene-acrylic emulsion in a mass ratio of (11-15): (6-9). According to the sound insulation coating for the building floor, the compound emulsion of the acrylic acid elastic emulsion and the acrylic acid styrene-acrylic emulsion is used as a basicglue emulsion of the coating, and the components such as the floating beads, the stone-free mineral wool, the mica powder and the butyronitrile rubber powder are matched for use, so the sound insulation coating has good sound insulation and shock absorption effects and also has excellent water resistance. The preparation method is mild in conditions and low in energy consumption, and can effectively prepare and produce the sound insulation coating for the building floor on a large scale.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a sound-insulating coating for building floors and a preparation method thereof. Background technique [0002] Noise refers to the sound that hinders people's normal rest, study and work, and the sound that interferes with the sound that people want to listen to. In today's society, noise has been listed as an important pollution. Noise pollution is likely to cause trouble and harm to people's health and daily life, cause people's irritability and depression, and is not conducive to people's physical and mental health. [0003] Today, with the rapid development of cities, there are more and more commercial housing, and people's requirements for commercial housing are also getting higher and higher. In commercial housing, due to the low density between buildings, the close connection between floors, and the low thickness of the floors, small sounds or vibrations s...
