Problems solved by technology

Among them, the prior art discloses a sound-insulating coating, but due to technical reasons, the sound-insulating filler in the coating is unevenly dispersed and easily agglomerated, and sedimentation and stratification are prone to occur. This technical defect directly reduces the sound-insulating effect of the coating.

Abstract

The invention discloses a modified asphalt waterproof coating, a preparation method for the modified asphalt waterproof coating and a use method thereof and relates to the field of building materials. The problems of sound insulation and noise reduction of the waterproof coating film can be solved. The preparation method for the modified asphalt waterproof coating disclosed by the invention comprises the following steps: preparing the modified asphalt waterproof coating from a component A and a component B; mixing and uniformly stirring anion emulsified asphalt, polymer emulsion and slurry, thereby acquiring the component A; and uniformly mixing water with curing agent, thereby acquiring the component B, wherein the slurry is prepared according to the following steps: adding water, stabilizer, dispersing agent, wetting agent, de-foaming agent, fine powder and pH regulator into a dispersing device, dispersing for the first time, adding a silencing filling material soaked with a silane coupling agent solution after ending the dispersing for the first time, and then adding a thickening agent, dispersing for the second time and then ending the dispersing for the second time, thereby acquiring the slurry. The modified asphalt waterproof coating disclosed by the invention has excellent effects of sound insulation and noise reduction on the basis of excellent waterproof property.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a preparation method of a modified asphalt waterproof coating, a modified asphalt waterproof coating and a use method thereof. Background technique [0002] With the rapid development of my country's economic construction, especially infrastructure, the demand for waterproof materials is increasing, and the scope of application is also expanding rapidly. There are many kinds of waterproof materials, especially environmental protection and multi-functionality become the main development direction of waterproof materials in the future. Among them, polymer modified asphalt has excellent waterproof performance, good elasticity, strong weather resistance, fatigue resistance, anti-aging and other characteristics, and has It has the advantages of reliability and economy, and is widely used in anti-seepage and waterproof projects such as basement floors, side walls, subways, tunnels, ro...
