UHPC explosion-proof plate and preparation method thereof
The invention discloses an explosion-proof plate, and particularly relates to a UHPC explosion-proof plate, the UHPC explosion-proof plate comprises a flexible buffer energy-absorbing layer and rigid protective layers glued on two sides of the flexible buffer energy-absorbing layer, and the rigid protective layers are prepared from the following raw materials in parts by weight: 600-1000 kg of cement, 50-200 kg of fly ash, 150-300 kg of silica fume, 5-10 kg of an expanding agent, 800-1500 kg of quartz sand and 5-15 kg of PVA fibers. 39 to 156 kg of copper-plated steel fiber, and 25 to 40 kg of polycarboxylate superplasticizer. According to the explosion-proof plate, the flexible buffering energy-absorbing layers are arranged on the two sides of the rigid composite layer, so that when the explosion-proof plate is impacted by a medium, the rigid protective layer can effectively absorb kinetic energy of the medium, meanwhile, the flexible buffering energy-absorbing layers can further absorb the kinetic energy of the medium, and the medium is prevented from penetrating through the flexible buffering layers and the rigid protective layer.
本发明公开了一种防爆板，具体为一种UHPC防爆板，本发明包括柔性缓冲吸能层以及胶合在柔性缓冲吸能层两侧的刚性防护层，其中，所述刚性防护层材料由以下重量份数的原料制备而成，水泥600‑1000kg，粉煤灰50‑200kg，硅灰150‑300kg，膨胀剂5‑10kg，石英砂800‑1500kg，PVA纤维5‑15kg，镀铜钢纤维39‑156kg，聚羧酸减水剂25‑40kg。本发明通过在刚性复合层的两侧设置柔性缓冲吸能层，使得防爆板在受到介质的冲击时，刚性防护层能够有效的吸收介质的动能，同时柔性缓冲吸能层能够进一步对介质的动能进行吸收，避免介质穿透柔性缓冲层与刚性防护层。
