展览馆中人流较为密集,火灾事件常有发生,故阻燃材料的存在显得尤为重要。针对博物馆、美术馆、科技馆等展览馆用阻燃材料进行分析,以两种阻燃剂为例,利用细观损伤力学法建立细观损伤力学模型,研究了保温材料和装饰材料的宏观力学性能,从而预测其使用寿命。研究发现,两种阻燃材料的使用,提高了建筑用保温材料和装饰材料的弹性模量,使其宏观力学性能显著提升,在添加阻燃材料后其使用寿命有了显著的提升。
The exhibition hall in more crowded flow of people, fire events often occur, so the existence of fire-retardant materials is particularly important. According to the analysis of flame retardant materials in museums, art galleries, science and technology museums and exhibition halls, taking the two kinds of fire retardants as an example, the meso-damage mechanics model is established by meso-damage mechanics method. The macroscopic mechanics of insulation materials and decorative materials are studied. Performance, to predict its useful life. The research shows that the use of two kinds of flame retardant materials increases the elastic modulus of thermal insulation materials and decorative materials for construction, and significantly improves the macroscopic mechanical properties. The service life of the two kinds of flame retardant materials has been significantly improved after the addition of flame retardant materials.
