Nanometer catalytic bactericidal gypsum suspended ceiling plate and preparation method thereof

Abstract

The invention discloses a nanometer catalytic bactericidal gypsum suspended ceiling plate and a preparation method thereof. The gypsum suspended ceiling plate is composed of a gypsum suspended ceiling plate layer and a nanometer catalytic bactericidal resin coating. The gypsum suspended ceiling plate layer comprises, by weight percentage, 45-55% of high-strength building gypsum powder, 5-10% of cement, 20-25% of modified diatomite, 1.5-2.5% of an auxiliary agent, 5-10% of a reinforced fiber, and 10-20% of water. The nanometer catalytic bactericidal resin coating comprises, by weight part, 100 parts of an aqueous polyurethane resin, 15-20 parts of Ag-TiO2 nanometer powder, 0.2-0.5 part of a coupling agent, and 1-1.5 parts of other auxiliary agent. The preparation method comprises: performing mixing and compacting and drying to obtain a gypsum suspended ceiling plate, and spraying a nanometer catalytic bactericidal resin over a gypsum suspended ceiling plate through an electrostatic spraying method. The prepared suspended ceiling plate is bactericidal, lightweight, and waterproof, and is easy to clean.

Description

technical field [0001] The invention specifically relates to a nano-catalyzed sterilized gypsum ceiling board, which belongs to the building material industry, and also relates to a preparation method of the nano-catalyzed sterilized gypsum ceiling board. Background technique [0002] Ceiling boards are widely used in home decoration and commercial decoration. At present, there are more and more types of ceiling boards on the market. With the continuous improvement of people's requirements for environmental quality after decoration, they have the advantages of beautifying the environment, safety and reliability, and are beneficial Healthy building materials are becoming more and more popular. [0003] At present, most of the research on ceiling panels is in the aspects of antimagnetic, sound absorption, and heat preservation. For example, Chinese Patent No. 200910053370.0 uses glass fiber reinforced high-strength gypsum powder to prepare porous gypsum ceiling panels with sou...
