Glass fiber reinforcing agent and preparation process thereof
The invention discloses a glass fiber reinforcing agent. The glass fiber reinforcing agent comprises the following components in percentage by weight: no less than 92.5% of calcium oxide, no more than1.2% of magnesium oxide, no more than 1.0% of silicon dioxide, no more than 0.2% of ferric oxide and no more than 0.25% of sulfur trioxide. The invention also discloses a preparation method of the glass fiber reinforcing agent. According to the preparation method, the continuity and stability of the whole calcining process are guaranteed through approach analysis, fixed-point purchasing and accurate metering, and meanwhile, a produced calcium oxide product has the advantages of high purity and low content of impurities such as silicon, magnesium and iron; by using an advanced mechanical shaftkiln for calcining and reasonably controlling material granularity, calcining temperature and time can be accurately set; meanwhile, the measures of stone washing and selection, balanced material distribution and the like are adopted, so the produced calcium oxide product is stable in quality and good in use performance; sodium chloride is added, so the calcining temperature can be remarkably reduced, the calcining time is shortened, and the purposes of saving energy and reducing consumption are achieved; and the tungsten trioxide is added, so the strength of subsequently prepared glass fibers is favorably improved.
本发明公开了一种玻璃纤维增强剂，包括以下重量百分比的成分：氧化钙≥92.5%、氧化镁≤1.2%、二氧化硅≤1.0%、三氧化二铁≤0.2%和三氧化硫≤0.25%。本发明的玻璃纤维增强剂的制备方法，通过进场分析，定点采购、准确计量保证了整个煅烧过程的连续稳定，同时使生产的氧化钙产品具有纯度高，硅、镁、铁等杂质含量低的优点；通过使用先进的机立窑煅烧和合理控制物料粒度，可以精确设定煅烧的温度和时间，同时采取石料洗选、均衡布料等措施，使生产的氧化钙产品质量稳定，使用性能好；加入氯化钠，可以显著降低煅烧温度，缩短煅烧时间，从而达到节能降耗的目的；加入三氧化钨，有利于提升后续制备的玻璃纤维的强度。
