Latest Patents

Li’s listed patent, “Pavement Coating Material and Preparation Method Thereof,” describes a coating made by combining organic and inorganic materials with additives. The preparation method first mixes a film-forming aid with a pure acrylic emulsion and a silane coupling agent with silica sol. It then prepares a catalyst solution using deionized water, dispersant, and a nano-catalyst. The organic and inorganic materials are stirred together, followed by the catalyst solution, hollow microbeads, titanium dioxide, and carbon black. A remaining portion of dispersant and a defoamer are added to complete the mixture. Li is credited with 1 patent.
