Problems solved by technology

[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 tech...

Embodiment Construction

[0018] The following will clearly and completely describe the technical solution in the embodiment of the invention in combination with this embodiment.

[0019] The applicant improved the processing technology and equipment, and obtained a liquid sound-insulating coating of the present invention after thousands of experiments and tests, which comprises: acrylic acid emulsion: 10-20%, emulsified asphalt: 10-20%, rubber powder 20 mesh: 30---50%, polystyrene particles: 5--15%, thickener: 0.1-0.5%, cross-linking agent: 0.1-0.3%, water: 2-20%, the acrylic emulsion It is an emulsion with a solid content of 50%, Tg: -20 degrees, that is, the transition temperature from the glass state to the high elastic state is minus 20 degrees Celsius, and has good water resistance and cement compatibility; the emulsified asphalt is an anionic and non-ionic The emulsified asphalt with ion as emulsifier has good compatibility with the acrylic emulsion.

[0020] The present invention adopts specia...

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...
