Problems solved by technology

[0003] The water-based waterproof coating can play the role of sound insulation and noise reduction by adding sound insulation materials, but due to the small bulk density of fly ash in the porous structure and the large particle gap, it has high oil absorption, and the emulsion coating effect and filling performance are poor, resulting in waterproof coatings The elongation performance of the film is rapidly attenuated, which eventually affects its waterproof effect

Abstract

The invention discloses high-stretch sound insulation two-component water-based waterproof paint and a preparation method thereof and relates to the technical field of waterproof paint. The waterproofpaint is composed of a liquid material and a powdery material. The liquid material comprises, by mass, 80% to 90% of a VAE emulsion, 1% to 3% of an antifoaming agent, 0.1% to 0.3% of a mildew preventive and 10% to 20% of water. The powdery material comprises, by mass, 50% to 70% of ash concrete with strength of 42.5, 2% to 4% of sodium hydroxide powder, 10% to 20% of quartz powder of 325 meshes,1% to 3% of a water reducing agent and 20% to 30% of fly ash. The waterproof paint has excellent sound insulation effects and excellent extension properties.

Description

technical field [0001] The invention relates to the field of waterproof coatings, in particular to a high-stretch sound-insulating two-component water-based waterproof coating and a preparation method thereof. Background technique [0002] With the continuous development and refinement of the domestic coatings industry, the market's requirements for coatings with special functions are becoming more and more prominent. In order to meet the requirements of various industries for waterproof coatings, it is necessary to produce high-performance and widely used waterproof coatings. [0003] The water-based waterproof coating can play the role of sound insulation and noise reduction by adding sound insulation materials, but due to the small bulk density of fly ash in the porous structure and the large particle gap, it has high oil absorption, and the emulsion coating effect and filling performance are poor, resulting in waterproof coatings The elongation performance of the film is...
