| titleOfInvention | Paper-surface gypsum board and preparation method thereof |
| abstract | The invention provides a paper-surface gypsum board and a preparation method thereof, wherein the core board raw material of the gypsum board comprises gypsum clinker, konjac flour and a negative oxygen ion material. Optionally, the board core raw material comprises gypsum clinker, konjac flour, an oxygen anion material, a binder and a foaming agent. The preparation method of the gypsum board comprises the following steps: firstly, mixing and stirring water, konjac flour and a negative oxygen ion material uniformly to obtain a negative oxygen ion additive mixed solution; secondly, adding a negative oxygen ion additive mixed solution, starch and a foaming agent into the gypsum clinker, and uniformly mixing to obtain gypsum slurry; then pouring the gypsum slurry on the surface protecting paper, and lapping, bonding and molding to prepare a wet plate; and finally, drying the wet board after the wet board is solidified, wherein the dried wet board is the paper-surface gypsum board. The addition of the konjac flour solves the adverse effect caused by easy agglomeration of the negative oxygen ion material, has a reinforcing effect on the gypsum board, and enables the gypsum board to have good negative oxygen ion releasing function, antibacterial effect and peculiar smell removing effect. |
