High-strength flame-retardant gypsum plaster board and manufacturing method thereof
The invention discloses a high-strength flame-retardant gypsum plaster board and a manufacturing method, and belongs to the technical field of artificial board production and manufacturing. Comprising surface protection paper, gypsum powder, a flame retardant, a reinforcing agent, rubber powder, glass fibers, a water reducing agent and a defoaming agent. Quantitatively adding the water reducing agent, the gypsum reinforcing agent and the rubber powder into water, and uniformly stirring; adding the weighed gypsum powder into water, stirring, adding the flame retardant, the glass fiber and the defoaming agent, and jointly and uniformly stirring; and pouring the stirred slurry into surface protection paper, carrying out filter pressing molding, and drying to obtain the high-strength flame-retardant gypsum board. The high-strength flame-retardant gypsum plaster board obtained through the method is compact in side face, uniform in glass fiber distribution and high in strength, can be used in a load-bearing mode, and reaches the national B1-level flame-retardant standard.
一种高强阻燃纸面石膏板及制造方法，属于人造板生产制造技术领域。包括护面纸、石膏粉、阻燃剂、加强剂、胶粉、玻璃纤维、减水剂、消泡剂。将减水剂和石膏加强剂、胶粉定量加入到水中，搅拌均匀；将称量好的石膏粉加入到水中搅拌，同时外加阻燃剂、玻璃纤维、消泡剂共同搅拌均匀；将搅拌好的浆料倒入护面纸中，压滤成型，烘干即得该高强阻燃石膏板。通过此方法获得的高强阻燃纸面石膏板，侧面致密，玻璃纤维分布均匀，强度高，能够承重使用，并且达到国家B1级阻燃标准。
