摘要/Abstract

摘要： 真空绝热板（VIP）作为一种新型保温材料,已在众多领域被广泛应用。然而,现有玻璃纤维短切丝芯材VIP存在回弹率高、使用寿命低等问题,限制了其进一步发展。针对此问题,通过在芯材中添加纳米气相SiO₂颗粒进行改性,制备出一种综合性能优异的颗粒改性复合VIP。实验系统评估了复合芯材的微观结构、分布均匀性以及压缩率与回弹率关键指标,并深入探讨了改性VIP的导热系数与气压敏感性。结果表明,颗粒改性复合VIP综合性能优异,随着气相SiO₂颗粒质量分数在0%~15%范围内递增,复合VIP的压缩率由63.9%下降至53.2%,回弹率由74.9%下降至64.3%,同时VIP的气压敏感性也呈现下降趋势。

Abstract: Vacuum insulation panels （VIP）, as a new type of insulation material, have been widely used in various industries. However, the existing chopped strand glass fiber core material VIP has the problems of high rebound rate and low service life, which limits its further development. Therefore, a particle-modified composite VIP with excellent comprehensive performance was prepared by adding nano fumed silica particles to the core material for modification. The microstructure, uniformity, compression rate and rebound rate of the as-prepared composite core material were tested, and the thermal conductivity and pressure sensitivity of the prepared VIP were studied. The results show that the particle modified composite VIP has excellent comprehensive performance, accompanied by a fumed silica particle mass fraction of 0%-15%. With the increasing of fumed SiO₂, the compression rate decreases from 63.9% to 53.2%, and the rebound rate decreases from 74.9% to 64.3%. At the same time, the pressure sensitivity of VIP also shows a downward trend.
