Formula and preparation method of pine needle fiber alkali corrosion resistant agent
The invention discloses a formula and a preparation method of a pine needle fiber alkali corrosion resistant agent, and relates to the technical field of constructional engineering. The coating at least comprises the following components in percentage by weight: 30 percent of silicon dioxide, 3 percent of hydroxypropyl methyl cellulose, 45 percent of mineral powder, 5 percent of fly ash, 5 percent of alkali-resistant emulsion and 12 percent of coalescing agent. The preparation method comprises the following steps of: preparing the silicon dioxide, the hydroxypropyl methyl cellulose, the mineral powder, the fly ash, the alkali-resistant emulsion and the coalescing agent, wherein the ratio of the silicon dioxide, the hydroxypropyl methyl cellulose, the mineral powder, the fly ash, the alkali-resistant emulsion and the coalescing agent is 30 percent; the prepared concrete alkali-resistant agent is introduced to absorb Ca (OH) 2 generated in the hydration process of cement, then microcrystals can be generated, the compactness and durability of the pine needle fiber foam concrete are improved, pine needle fibers in the pine needle fiber foam concrete can resist the erosion effect of the Ca (OH) 2 alkali corrosion environment in the concrete, and therefore the concrete alkali-resistant performance is improved. The durability of the concrete is improved, the service life of the concrete is prolonged, and the later maintenance cost of the concrete is reduced.
本发明公开了一种松针纤维抗碱腐蚀剂的配方及制备方法，涉及建筑工程技术领域。本发明至少包括二氧化硅、羟丙基甲基纤维素、矿粉、粉煤灰、抗碱乳液和成膜助剂，所述二氧化硅占比为30％，羟丙基甲基纤维素占比为3％，矿粉占比为45％，粉煤灰占比为5％，抗碱乳液占比为5％，成膜助剂占比为12％。本发明首先通过引入制备的混凝土抗碱剂，吸收水泥在水化过程中产生的Ca(OH)2，然后可以生成微晶体，提高松针纤维泡沫混凝土的密实性与耐久性，能够使松针纤维泡沫混凝土中松针纤维抵抗混凝土内部Ca(OH)2碱腐蚀环境的侵蚀作用，不仅提高了混凝土的耐久性能和使用寿命，还降低了混凝土的后期维护的费用。
