The patent application (Publication Number: US20230416152A1) discloses a novel plaster composition designed for fire-resistant plasterboards. The composition includes hydratable calcium sulphate, water, SiO2 particles, CaCO3, and polysiloxane in specific weight percentages relative to the hydratable calcium sulphate. The SiO2, CaCO3, and polysiloxane concentrations are further detailed in the claims, with specific forms of CaCO3 and SiO2 specified for optimal performance. The composition is notably free of vermiculite and can contain mica within a defined range for enhanced properties.
Furthermore, the patent application outlines a method for manufacturing plasterboards with a density greater than 0.55 using the disclosed plaster composition. The method involves forming the plaster composition into a plasterboard and allowing it to set, resulting in a high-density gypsum core. Additionally, the application describes a partition wall design comprising two layers of plasterboards, with at least one layer manufactured using the disclosed method. The method also includes a step to reduce shrinkage during heat exposure, ensuring structural core cohesion at high temperatures. Overall, the patent application presents a comprehensive approach to developing fire-resistant plaster compositions and manufacturing methods for high-density plasterboards with improved performance characteristics.
