Preparation method of asbestos-free plant fiber reinforced calcium silicate board and asbestos-free plant fiber reinforced calcium silicate board
The invention relates to a preparation method of an asbestos-free plant fiber reinforced calcium silicate board and the asbestos-free plant fiber reinforced calcium silicate board. The preparation method comprises the following steps: S1, soaking and softening raw ramie with water, and carrying out steam explosion to obtain a ramie explosion material; S2, boiling off the ramie blasting material inan alkaline degumming solution, and performing washing with water and drying to obtain ramie fibers; S3, spraying a gamma-aminopropyltriethoxysilane modifier to the ramie fibers to prepare modified ramie fibers; S4, mixing the modified ramie fibers, water, silica fume, metakaolin, potassium sulfate, slaked lime, Portland cement, diatomite and quartz sand to obtain mixed slurry; and S5, preparingthe mixed slurry into a plate blank, and carrying out pre-curing, autoclaved curing and drying. According to the calcium silicate board, the modified ramie fibers are adopted as a reinforcing material, and the board is good in appearance quality, low in water absorption rate and wet expansion rate, good in water resistance and moisture resistance, high in mechanical property, resistant to freezingand thawing, good in dry-wet cycle resistance and stable in property.
本发明涉及一种无石棉植物纤维增强硅酸钙板的制备方法及无石棉植物纤维增强硅酸钙板，该制备方法包括：S1.将苎麻原麻用水浸渍软化后进行蒸汽爆破得苎麻爆破料；S2.将苎麻爆破料置于碱性脱胶液中煮练后经水洗、烘干得苎麻纤维；S3.向苎麻纤维喷洒γ‑氨丙基三乙氧基硅烷改性剂制备改性苎麻纤维；S4.将改性苎麻纤维、水、硅灰、偏高岭土、硫酸钾、消石灰、硅酸盐水泥、硅藻土、石英砂混合制得混合浆料；S5.将混合浆料制成板坯，经预养护、蒸压养护、干燥即得。该硅酸钙板采用改性苎麻纤维作为增强材料，板材外观质量好，吸水率和湿涨率低，具有较好的耐水耐湿性，力学性能高，抗冻融、抗干湿循环性能好，性质稳定。
