| titleOfInvention | A kind of gypsum board and preparation method thereof |
| abstract | The present application discloses a paper-faced gypsum board and a preparation method thereof. The paper-faced gypsum board includes a board core and a cover paper, and the board core raw materials include, in parts by weight: 100 parts of gypsum clinker, hollow microspherical 0.3 to 10 parts of acrylonitrile-based copolymer; after the gypsum clinker is hydrated, partially prepared dihydrate gypsum crystals pass through the shell layer of the hollow microspheres and are inserted into the hollow microspheres. The paper-faced gypsum board provided by the application solves the problem of uneven distribution of cells in the gypsum board; solves the problem of the toughness of the gypsum board, improves the fold-to-compression ratio of the gypsum board, and makes the board have better flexibility; it improves the mechanical strength of the gypsum board. On the basis of the gypsum board, the lightweight of the gypsum board is realized. The paper-faced gypsum board provided by the present application has low thermal conductivity and good thermal insulation effect. |
