摘　　要：弹性地板因其质轻、安装简单、性能稳定等优点被广泛应用于室内外装修。临界热辐射通量是表征铺地材料在外部热辐射条件下火焰蔓延能力高低的检测项目。本文对PVC地板、LVT地板、WPC地板、SPC地板、橡胶地板和亚麻地板的临界热辐射通量检测结果进行比较。结果表明,PVC同透地板、LVT地板、WPC地板、SPC地板的临界热辐射通量值基本可达8.0kW/m^(2)以上,燃烧性能等级达到B1(B-s1)级,PVC复合地板、橡胶地板及亚麻地板的燃烧性能稍差,燃烧性能等级一般在B1(C-s1)级。Resilient floors are widely used in indoor and outdoor decoration because of the advantages such as light weight,simple installation and stable performance.The critical heat flux is an important test item that characterizes the flame spread ability of flooring materials under external heat radiation conditions.This paper compares and analyzes the test results of critical heat flux of PVC floor,LVT floor,WPC floor,SPC floor,rubber floor and linen floor.The results show that the critical heat radiation flux of PVC floor,LVT floor,WPC floor and SPC floor can basically reach more than 8.0kW/m^(2),and the combustion level reaches B1(B-s1).The combustion performance of PVC composite floor,rubber floor and linen floor is slightly poor,and the combustion level is generally B1(C-s1).
