- 摘要:
- 为了探讨醇酸清漆对典型装饰木材火灾危险性的影响，利用热重分析、差热分析、木垛法、隧道法和塑料烟密度仪对装饰木材的燃烧性能、热解特性和生烟特性进行了分析。结果表明，木材及其表面涂覆的醇酸清漆主要热失重发生在200~500℃，其中木材的热解过程为先吸热、后放热的过程，而醇酸清漆为吸热过程。与未涂覆清漆的木材相比，清漆使木材在燃烧过程中质量损失、有焰燃烧时间及火焰传播比值明显增加。同时，醇酸清漆的烯烃结构和苯环结构还导致木材的比光密度、质量光密度增大，烟气危害增大，从而进一步增大了火灾危险性。此外，装饰木材的生烟特性还受火焰条件和辐射功率的影响，高辐射功率和有焰条件下材料的比光密度和质量光密度均较低。
- Abstract:
- To explore the influence of alkyd varnishon fire risk of decorative wood, the thermo-gravimetric analyzer, differential scanning calorimeter, wood stack method, tunnel method and plastic smoke density tester were used to analyze the flammability, pyrolysis characteristics and smoke properties of thedecorative materials. The results show that the loss of maximum mass of the wood and alkyd varnish occurs in the range of 200~500℃.In the pyrolysis process, the wood exhibits an obvious endothermic process and then an exothermic one, while the alkyd varnish exhibits an obvious endothermic process only. Compared with the wood without alkyd varnish, the mass loss, during of flaming and fire spread ratio of the wood consisted alkyd varnish are increased significantly. Otherwise, due to the olefin structure and benzene ring structure of alkyd varnish, both the special optical density and mass optical density of the decorative wood consisted alkyd varnish are increased. Moreover, external heat flux and ignition source all affect the smoke properties of the decorative wood. The high external heat flux and application of an ignition source in the smoke density test decrease the special optical density and mass optical density of the decorative wood.
