A liquid soundproof coating

Abstract

The invention discloses a liquid sound-proof coating, which comprises, by weight percentage: acrylic acid emulsion: 10-20%, emulsified asphalt: 10-20%, rubber powder 20 mesh: 30-50%, polystyrene particles: 5-15% %, thickener: 0.1‑0.5%, crosslinking agent: 0.1‑0.3%, water: 2‑20%, the acrylic emulsion contains 50% solid, Tg:‑20 degrees, has good water resistance and cement phase Compatible emulsion; the emulsified asphalt is an emulsified asphalt using anion and non-ion as emulsifiers, forming a matching compatibility with the acrylic emulsion. The material and material components of the invention are easy to obtain, low in cost, convenient in construction, can form a flexible sound insulation pad with multiple tiny cavities, can effectively reduce impact force, and have good sound insulation durability.

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
