High-light-transmittance heat-insulation fireproof glass and preparation method thereof
The invention relates to high-light-transmittance heat-insulation fireproof glass and a preparation method thereof. The preparation method comprises the following steps: weighing the following raw materials in percentage by mass: 4-6% of an anti-condensing agent, 1% of a water-based defoaming agent, 65-70% of a silicon dioxide aqueous solution and 25-30% of a potassium hydroxide solution, and preparing a fireproof solution; laminating the first glass substrate, the middle piece and the second glass substrate, wherein a hollow cavity is formed between the first glass substrate and the second glass substrate; and pouring the fireproof liquid into the hollow cavity, and drying and curing to obtain the high-light-transmittance heat-insulating fireproof glass. According to the application, the proportion of the silicon dioxide aqueous solution is increased to 65-70%, and the ratio of SiO2/k2O is increased to 4.5-5.5, so that the crosslinking degree of silicon-oxygen bonds can be increased, the chemical stability of the silicon-oxygen bonds can be improved, the problems of bubbles generated in the use process, reduction of visible light transmittance, yellowing and the like are avoided, and meanwhile, the thermal stability and the fireproof performance are also improved.
本申请涉及一种高透光率隔热防火玻璃及其制备方法。该制备方法包括以下步骤：按照质量百分比为4％‑6％的抗冷凝剂、1％的水性消泡剂、65％‑70％的二氧化硅水溶液及25％‑30％的氢氧化钾溶液称取原料，并配置防火液；将第一玻璃基材、中间件及第二玻璃基材合片，第一玻璃基材与第二玻璃基材之间形成中空腔；将防火液灌注于中空腔中，并烘干固化，得到高透光率隔热防火玻璃。本申请通过将二氧化硅水溶液的比例提高至65％‑70％，使SiO_2/k_2O的比值提高至4.5‑5.5，如此可以提高硅氧键交联度，提高其化学稳定性，避免在使用过程中产生的气泡、可见光透过率降低和发黄等问题，同时热稳定性和防火性能也有所提高。
