Piezoelectric material modified composite explosion-proof structure and preparation method thereof
The invention relates to a piezoelectric material modified composite explosion-proof structure and a preparation method thereof, and belongs to the technical field of explosion-proof structures. The technical problems that in the prior art, a concrete explosion-proof structure is large in weight, a foamed aluminum explosion-proof structure is high in price, and the explosion-proof performance cannot meet the high explosion-proof requirement are solved. According to the composite explosion-proof coating disclosed by the invention, firstly, electric-conducting and heat-conducting high-modulus polyurethane is prepared, then, piezoelectric material/polyurethane composite material supercritical foaming particles are prepared, then, layered structures with different hardness and density are prepared, and finally, the different layered structures are sequentially increased and bonded according to the density from the interior of a wall body to the exterior of the wall body. The piezoelectric material modified composite explosion-proof structure is obtained. According to the piezoelectric material modified composite explosion-proof structure, the effect of the material in explosion shock wave attenuation is improved to the maximum extent, the excellent explosion-proof performance is achieved, and the piezoelectric material modified composite explosion-proof structure can achieve the good explosion-proof effect at the low thickness.
本发明涉及一种压电材料改性复合防爆结构及其制备方法，属于防爆结构技术领域。解决了现有技术中的混凝土防爆结构重量大，而泡沫铝防爆结构价格高、防爆性不能满足高防爆要求的技术问题。本发明的复合防爆涂层，先制备导电导热高模量聚氨酯，然后制备压电材料/聚氨酯复合材料超临界发泡颗粒，然后制备硬度、密度不同的层状结构，最后将不同的层状结构按照密度从墙体内到墙体外依次变大粘结，得到压电材料改性复合防爆结构。本发明的防爆结构最大程度的提高材料在爆炸冲击波衰减中的作用，实现优异的防爆性能，且本发明的压电材料改性复合防爆结构在低厚度就能实现很好的防爆效果。
