Fiber-reinforced geopolymer using waste paper fiber as raw material, preparation method and application
The invention relates to a fiber-reinforced geopolymer using waste paper fiber as a raw material, and a preparation method and application thereof, and belongs to the technical field of decoration materials. The geopolymer is prepared from the following raw materials in parts by weight: 20 to 50 parts of slag powder, 50 to 80 parts of fly ash, 20 to 50 parts of waste paper fiber slurry, 40 to 80 parts of fine sand, 8 to 10 parts of water glass, 0.5 to 1.5 parts of sodium hydroxide, 0.5 to 1.0 part of polyvinyl alcohol fiber and 35 to 45 parts of water. The preparation method comprises the following steps: uniformly mixing the raw material components according to a certain sequence, pouring and molding the finally prepared mixture, vibrating on a vibrating table, demolding, and curing to obtain the geopolymer. According to the geopolymer, slag powder, fly ash and waste paper fibers are used as raw materials, sodium silicate and sodium hydroxide are used for excitation, polyethylene glycol fibers are doped to improve the bending strength of the geopolymer, the use ratio of the waste paper fibers in the raw materials is 30% or above, and full utilization of waste paper is achieved. The geopolymer can be used as a base material of an environment-friendly decorative plate, has fire resistance of grade B1 or above, and is formaldehyde-free.
本发明涉及一种以废纸纤维为原料的纤维增强地聚合物、制备方法和应用，属于装饰装修材料技术领域。所述地聚合物原料按重量份计，组成为：矿渣粉20～50份，粉煤灰50～80份，废纸纤维料浆20～50份，细砂40～80份，水玻璃8～10份，氢氧化钠0.5～1.5份，聚乙烯醇纤维0.5～1.0份，水35～45份。通过将原料组分按一定顺序混合均匀，将最终制得的混合物浇筑成型，在振动台振动后拆模，养护后得到所述地聚合物。所述地聚合物利用矿渣粉、粉煤灰及废纸纤维作为原料，用水玻璃和氢氧化钠激发，并掺入聚乙醇纤维提高其的抗弯强度，废纸纤维在原料中的使用比占30％以上，实现了废纸的充分利用。所述地聚合物可作为环保型装饰板的基材，具有B1级以上的耐火能力，且无甲醛。
