Liquid sound insulation coating

Abstract

The invention discloses a liquid sound insulation coating. The liquid sound insulation coating comprises the following components in percentage by weight: 10-20% of an acrylic emulsion, 10-20% of emulsified asphalt, 30-50% of rubber powder with 20 meshes, 5-15% of polystyrene particles, 0.1-0.5% of a thickening agent, 0.1-0.3% of a cross-linking agent and 2-20% of water, wherein the acrylic emulsion is an emulsion with the solid content of 50%, the Tg is -20 degrees, good water resistance and good cement compatibility are achieved; wherein the emulsified asphalt is emulsified asphalt adoptinganions and non-ions as emulsifiers, and forms matching compatibility with the acrylic emulsion. The material components are easy to obtain, the cost is low, the construction is convenient, the flexible sound insulation pad with a plurality of tiny cavities can be formed, the impact force can be effectively reduced, and the sound insulation durability is good.

Description

technical field [0001] The scheme belongs to the field of chemical materials, specifically the application field of building chemical materials. Background technique [0002] With the improvement of people's living standards, large-scale, low water absorption bricks are widely used in home decoration, which has led to the vigorous development of tile adhesive products! However, in the Chinese market, there are still very few tile adhesives used on the ground to lay tiles. One of the influencing factors is that in residential commercial housing, the use of floor tile adhesives to stick tiles can increase the floor space and reduce construction costs. At the same time, it also brings the problem of poor sound insulation effect on the ground. [0003] At present, the ground sound insulation technology mainly has the following methods: 1. The method of laying carpets can absorb impact energy, but it is not suitable for families, shopping malls and office buildings with tile fac...

[0002] With the improvement of people's living standards, large-scale, low water absorption bricks are widely used in home decoration, which has led to the vigorous development of tile adhesive products! However, in the Chinese market, there are still very few tile adhesives used on the ground to lay tiles. One of the influencing factors is that in residential commercial housing, the use of floor tile adhesives to stick tiles can increase the floor space and reduce construction costs. At the same time, it also brings the problem of poor sound insulation effect on the ground.

[0003] At present, the ground sound insulation technology mainly has the following methods: 1. The method of laying carpets can absorb impact energy, but it is not suitable for families, shopping malls and office buildings with tile facings; 2. The method of floating sound insulation floors requires an overhead floor , The construction is complicated, the cost is high, and the height of the net floor space is compressed; 3. The sound insulation mortar method, the construction is relatively simple, but it requires a thickness of at least 3cm to have a certain effect, and there is a shortcoming of compressing the net space height of the floor and the sound insulation effect is limited
