The invention discloses flame-retardant transparent concrete, which is composed of the following components in percentage by weight: 15-25% of epoxy resin; 5-10% of a curing agent; 55-70% of glass particles; 5-10% of a flame retardant; wherein the flame retardant is formed by mixing aluminum hydroxide, expansible graphite and tris (2-chloroisopropyl) phosphate according to the weight ratio of 10: (1-3): (0.1-0.5); the synergistic effect among three different types of flame retardants, namely aluminum hydroxide, expansible graphite and tris (2-chloroisopropyl) phosphate is adopted, so that the generation of a carbon layer is promoted, the development of smoke and flame is prevented, and the flame-retardant effect is enhanced; meanwhile, due to the addition of the flame retardant, a composite system of the resin, the aluminum hydroxide and the expansible graphite increases the interface bonding force of the material, and the hardness of the material is improved; and the aluminum hydroxide particles can generate relative slippage in the resin, so that microcracks generated in the stretching process are quickly bridged, and the strength of the concrete is improved.
本发明公开一种阻燃透明混凝土，由以下重量百分比的组分组成:环氧树脂15‑25％；固化剂5‑10％；玻璃颗粒55‑70％；阻燃剂5‑10％；其中，所述阻燃剂由氢氧化铝、可膨胀石墨、三(2‑氯异丙基)磷酸酯按重量比10:1‑3:0.1‑0.5混合而成；采用氢氧化铝、可膨胀石墨、三(2‑氯异丙基)磷酸酯三种不同类型阻燃剂之间的协同效应，促进炭层的生成，阻止烟和火焰的发展，增强阻燃效果；同时由于阻燃剂的加入，树脂与氢氧化铝、可膨胀石墨的复合体系增加了材料的界面结合力，材料硬度提高；并且氢氧化铝粒子可在树脂内部产生相对滑移，使在拉伸过程中发生的微裂纹迅速弥合，从而提高混凝土的强度。
