Fireproof external wall foam gypsum insulation board produced from alpha high-strength gypsum and preparation method thereof
The invention discloses a preparation method and application for producing a fireproof external wall foam gypsum insulation board by using a low-cost high-efficiency alpha high-strength gypsum preparation material. The fireproof external wall foam gypsum insulation board produced from alpha high-strength gypsum comprises the following raw materials in percentage by weight: 75-85% of alpha high-strength gypsum powder; 0.1 to 0.5 percent of foaming agent; when the concentration of the sulfuric acid is 98%, the concentration of the aggregate is 0.3-0.8%. The total weight of the components is 100%. And uniformly mixing the raw materials, and carrying out composite molding with covering paper to prepare the alpha high-strength gypsum board. The alpha high-strength fireproof external wall foam gypsum insulation board obtained by the invention is detected to meet the requirements of GB/T9775-2008'gypsum plaster board ', and the 30 min fluidity loss, the initial setting time, the final setting time, the breaking strength, the compressive strength and the shrinkage rate all meet the requirements.
本发明公开了一种以低成本高效α高强石膏制备材料生产防火外墙泡沫石膏保温板的制备方法和应用。本发明的α高强石膏生产防火外墙泡沫石膏保温板以重量百分数计，原料配方如下：α高强石膏粉：75～85％；发泡剂：0.1～0.5％；集料：15～25％，硫酸浓度为98％时，0.3～0.8％。以上总重量满足100％。然后将原料混匀，与覆面纸复合成型制得α高强石膏板材。本发明所得的α高强防火外墙泡沫石膏保温板经过检测，达到GB/T9775—2008《纸面石膏板》要求，30min流动度损失、初凝时间、终凝时间、抗折强度、抗压强度、收缩率，都符合要求。
