摘　　要：在节能减排和“双碳”目标的大背景下,集多功能为一体的无机复合聚苯A级保温板亟待研发。气凝胶和多孔沸石具有多孔的结构特点,是优异的低导热系数材料。本文合成了气凝胶-多孔沸石复合料,研究了不同聚苯乙烯(EPS)颗粒、气凝胶-多孔沸石复合料和改性剂掺量对气凝胶-多孔沸石复合料负载无机复合聚苯保温板(AIPIB)干密度、导热性能、力学强度、防火及防水性能的影响规律,制得一种干密度为152 kg/m^(3)、导热系数低于0.050 W/(m·K)、燃烧性能A级、14 d抗压强度高于0.15 MPa、饱水7 d吸水率低于5%的AIPIB,且AIPIB界面黏结良好;与《热复合聚苯乙烯泡沫保温板》(JG/T 536—2017)规定的A级保温板性能相比,此AIPIB具有更低的导热系数、更高的抗压强度、更优异的防水和防火性能,同时无机与有机组分黏结性能良好,综合优势明显。Under the background of energy saving,emission reduction and"double carbon"target,it is urgent to develop a type of inorganic composite polystyrene A class thermal insulation board integrated with diversified functions.Aerogels and porous zeolites possess porous structural characteristics and are excellent materials with low thermal conductivity coefficient.In this paper,aerogel-porous zeolite composite was firstly synthesized,and the influences of different dosages of EPS particles,aerogel-porous zeolite composite and modifying agent on the dry density,thermal conductivity,mechanical strength,fire prevention and waterproof performance of aerogel-porous zeolite composite loaded inorganic composite polystyrene insulation board(AIPIB)were comprehensively studied.AIPIB with dry density of 152 kg/m^(3),thermal conductivity coefficient of lower than 0.050 W/(m·K),combustion performance of class A,14 d compressive strength of higher than 0.15 MPa,7 d saturation absorption of less than 5% is achieved,and the interface bonding of AIPIB is good.Compared with the performance of the A class thermal insulation board specified in“Thermal composite polystyrene foam insulation board”(JG/T 536—2017),AIPIB has lower thermal conductivity coefficient,higher compressive strength,better waterproof and fire prevention performance,and the bonding performance between inorganic and organic component is good with outstanding comprehensive advantages.
