Abstract

The invention belongs to the technical field of floor coatings, and provides a novel damping sound insulation coating meeting green building requirements and a preparation method thereof. The dampingsound insulation coating comprises powder and a liquid, and the powder comprises, in parts by weight, 60-110 parts of rubber particles, 2-8 parts of anti-cracking fibers, 180-500 parts of special cement, 100-400 parts of floating beads and 8-50 parts of additives, wherein the mass ratio of the powder to the liquid is 1.2:1. By adding the floating beads, a closed air chamber in the coating is increased, the loss of sound conduction is increased, the fluidity, hardness and wear resistance of the coating can be improved, meanwhile, the gloss of the coating can be controlled, and the cost is reduced; the damping sound insulation coating is high in cohesiveness, high in anti-permeability strength, good in crack resistance, high in low-temperature severe environment adaptability and capable of effectively overcoming adverse factors such as water immersion and rapid aging.

Description

Technical field[0001]The invention belongs to the technical field of floor coating construction, and in particular relates to a novel damping sound insulation coating meeting the requirements of green buildings and a preparation method thereof.Background technique[0002]At present, building energy consumption has been tied with industrial energy consumption and transportation energy consumption, making it the three major “energy-consuming consumers” in my country. In particular, the energy consumption of buildings is rising sharply along with the continuous increase of the total building volume and the improvement of living comfort. Therefore, it is necessary to introduce the concept of circular economy, develop green buildings, and promote the harmonious development of entrance, architecture and environment. In order to promote the development of green buildings, the Ministry of Construction has established a green building professional committee and other relevant institutions, and...
