AI Technical Summary
Technical Problem
Among existing explosion-proof structures, concrete structures are heavy, while foamed aluminum structures are expensive and lack sufficient explosion-proof performance, failing to meet high explosion-proof requirements.
Method used
A piezoelectric material-modified composite explosion-proof structure is adopted. By preparing a multi-gradient layered structure, using conductive and thermally conductive high-modulus polyurethane as the matrix, and combining piezoelectric material/polyurethane composite supercritical foaming particles, the material achieves the attenuation effect of explosion shock waves.
Benefits of technology
Achieving excellent explosion-proof performance with low thickness, meeting high explosion-proof requirements, and reducing material weight and cost.

Abstract
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。
