Abstract

The invention belongs to the technical field of sheet material preparation, and more specifically relates to a preparation method of a moistureproof plasterboard. The preparation method comprises following steps: wollastonite is taken as a raw material, and is mixed with distilled water to prepare a wollastonite suspension solution; the wollastonite suspension solution is reacted with hydrochloricacid so as to obtain a mixed solution, and the mixed solution and sunflower oil are subjected to blending fermentation so as to obtain modified wollastonite; arenga engleri is taken as a raw material, and is subjected to gas explosion treatment so as to obtain arenga engleri fiber; isopropanol is taken as an alkylating agent for alkylation processing of arenga engleri fiber so as to obtain alkylated arenga engleri fiber which is taken as modified arenga engleri fiber; orange peel essential oil is taken as a raw material, the modified arenga engleri fiber and orange peel essential oil are mixed, stirred, and reacted so as to obtain a mixture; and at last, the modified wollastonite and the mixture are mixed for reaction, an obtained product is introduced into a die for curing and drying soas to obtain the moistureproof plasterboard. The moistureproof plasterboard is low in water absorption rate, and excellent in moisture resistance, at an environment with relatively large temperature difference, cracking times are few, compressive strength is high, impact resistance is excellent, and the application prospect is promising.

Description

technical field [0001] The invention discloses a method for preparing a moisture-proof gypsum board, which belongs to the technical field of board preparation. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels that are currently being developed. Gypsum boards have been widely used in interior partition walls, wall cladding panels (replacing plastering layers), ceilings, sound-absorbing panels, ground sub-boards and various Decorative panels, etc., for indoor use should not be installed in the bathroom or kitchen. [0003] The gypsum boards produced in my country mainly include: paper gypsum boards, paperless gypsum boards, decorative gypsum boards, gypsum hollow slats, fiber gypsum boards, gypsum sound-absorbing panels, anchor...
