Benefits of technology

This patented technology describes different ways to improve the quality (uniform distribution) and thickness of aquatic barriers made from plastic films used in construction projects such as dams or leaks caused by cracks due to factors like temperature changes over long periods without losing their integrity. By adding nanoparticles called silicon dioxide onto these resin particles instead of just one type of particle per unit volume, this new composition becomes evenly distributed throughout the resulting product while maintaining good properties. Overall, this innovative solution helps create stronger structures through improved bond between layers within the final product.

Problems solved by technology

Technologies described involve combining different types of plastiscent agents (PVC) into a single composition without causing damage when exposed to moisture environments like rainwater. These compositions provide excellent performance including durable water repelling property, impact resistance, insulation against heat transfer, self-heal function, and preventive measures against rust development. They may be applied over large areas at once, reducing costs compared to traditional methods requiring multiple layers of paint.

Abstract

The invention relates to the field of waterproof coatings, and discloses a nano densified polymer-based waterproof coating and a preparation method thereof. The preparation method comprises the following steps: (1) sequentially adding aluminum trichloride and nano zeolite powder into water, and filtering and drying to obtain an aluminum trichloride/zeolite powder composite material, (2) carrying out ball milling treatment on the composite material, then adding polyvinyl alcohol and water, and uniformly stirring to obtain a polyvinyl alcohol coated aluminum trichloride/zeolite powder compositematerial, and (3) uniformly mixing the composite material with barite powder, nano silicon dioxide, polymer redispersible rubber powder, Portland cement and a thickening agent to obtain the nano densified polymer-based waterproof coating. The polymer-based waterproof coating prepared by the invention contains the polyvinyl alcohol-coated aluminum trichloride/zeolite powder composite material, so that the defect can be slowly filled with the stone aluminum trichloride when the coating has the defect, and meanwhile, a gel film is formed to seal micropores, so that a waterproof layer is denser, and the waterproof performance of the waterproof coating is improved.
