阻燃细木工板体系的燃烧和理化性能

选取不同类型的阻燃体系制备阻燃细木工板,通过建材难燃性实验炉、建材烟密度仪、建材毒性试验装置等燃烧性能检测装置及万能力学试验机等理化性能检测装置进行测试,筛选出适用于细木工板的阻燃体系。试验表明,水基型阻燃剂FR-W能够对细木工板起到较好的阻燃效果,达到阻燃B1级要求,但由于木材本身特性,产烟毒性只能达到ZA3级;在保证低甲醛含量的前提下,水基型阻燃剂的加入会对细木工板的浸渍剥离性能产生负面影响。

The combustion and physical properties of biockboard fire retardant system

The flame retardant blockboard was prepared by the selected different kinds of fire retardant and examined by building materials fire resistant furnace,building materials smoke densitometer,building materials toxicity testing device and the universal mechanical testing machine.The results indicated that the blockboard with FR-W as fire retardant system could reach to B1 level,but owning to its own characteristics,the smoke toxicity could only reach the ZA3 level;under the premise of low formaldehyde content,the use of water-based fire retardant played an adversely effect to the blockboard of it’s dipping & peeling-off performance.
