Preparation method of thermal insulation gypsum board
The invention discloses a preparation method of a thermal insulation gypsum board. The preparation method comprises the following steps: uniformly mixing gypsum powder, a coagulant, glass fibers, wood fibers and starch to obtain a material body A; foaming the foaming agent to serve as a material body B; and simultaneously adding the material body A, the material body B, the water reducing agent, the emulsion and the water into a mixer through an independent pump, uniformly stirring, and mixing to obtain the gypsum slurry. And placing the gypsum slurry between the upper and lower layers of surface protection paper, and carrying out extrusion molding to obtain the gypsum board. According to the invention, the wood fiber is added into the gypsum board as an auxiliary material and is mixed and stirred together with the gypsum powder, and a three-dimensional network structure with an obvious cross-linking effect of the wood fiber is fully utilized, so that the tension effect between gypsum board cores is improved, and the toughness, the heat preservation property and the nail-holding power of the board are improved.
本发明公开了一种保温石膏板的制备方法，包括以下步骤：将石膏粉、促凝剂、玻璃纤维、木质纤维、淀粉混合均匀作为料体A；将发泡剂发泡完成作为料体B；将料体A、料体B、减水剂、乳液和水均通过单独的泵同时加入混合机搅拌均匀，混合成石膏浆。将石膏浆放置在上下两层护面纸之间挤压成型后得到石膏板。本发明将木质纤维作为辅料添加到石膏板中，与石膏粉一同混合搅拌，充分利用其具有明显交联效应的三维网状结构，提高石膏板芯之间的拉力作用，从而提高板材的韧性、保温性和握钉力。
