Latest Patents

Qingxin Liu holds a patent for a method of siloxane polymerization in wallboard. This patent describes an improved process for polymerizing siloxane using a gypsum-based slurry that includes stucco, Class C fly ash, magnesium oxide, and an emulsion of siloxane and water. The method involves creating an emulsion of siloxane and water, combining it with a dry mixture of stucco, magnesium oxide, and Class C fly ash, and then shaping the slurry as desired. Once the stucco sets, the siloxane polymerizes, resulting in a water-resistant gypsum panel. This panel features a core made of interwoven matrices of calcium sulfate dihydrate crystals and silicone resin, with a catalyst comprising magnesium oxide and components from Class C fly ash dispersed throughout.
