【摘要】：随着经济的发展与进步,人们已经越来越重视生活的品质,导致了内装饰材料的广泛的使用。由于内装饰材料会为室内火灾发生提供可燃物,因此对内装饰材料用阻燃涂料进行阻燃处理从而降低其燃烧性能,可以起到预防室内火灾的作用。松木是大多数内装饰材料的原材料,因此可以作为阻燃涂料的实验基材使用,再结合阻燃涂料无卤化以及环保的要求,因而选用适合木材使用的磷系阻燃涂料三(2-氯乙基)磷酸酯(TCEP)以及氮系阻燃涂料碳酸胍。将TCEP以及碳酸胍分别配制成不同浓度的阻燃涂料,对松木片进行阻燃处理,然后对经过阻燃处理的松木片进行热重分析,通过实验结果数据分析各自的阻燃效果的优劣,在多次实验后,得到浓度为60%的TCEP阻燃涂料使松木片的阻燃性能达到最佳,经过其处理的松木片在热分解过程中到达最大热释放速率的温度提高了90℃左右,最终残余量由原来的20%提升至63%；而使松木片阻燃性能达到最佳阻燃效果的碳酸胍阻燃涂料的使用浓度为70%,经过其处理的松木片在热分解过程中到达最大热释放速率的温度提高了85℃左右,最终残余量由原来的20%提升至58%。阻燃涂料的协同作用研究是今后阻燃涂料运用的重要方向,而磷系和氮系阻燃涂料在理论上又有很好的协同效应,因此将TCEP与碳酸胍进行不同比例的配比,分别配制成浓度为70%和60%的混合阻燃涂料,依次对松木片进行阻燃处理,然后进行热重分析,实验结果发现浓度为70%进行协同阻燃时,TCEP与碳酸胍的最佳比例为1：3,经其处理的松木最终残余量为66%,最大热释放速率时的温度提高至379℃左右；而浓度为60%进行协同阻燃时,TCEP与碳酸胍的最佳比例则为3：1,经其处理的松木片最终残余量为65%,最大热释放速率时的温度提高到375℃左右。然后对这两种处理过的松木片进行氧指数测试,发现浓度为70%并且TCEP与碳酸胍比例为1：3时松木片的氧指数较高,因而,松木片阻燃效果最好的方法为使用浓度为70%且TCEP与碳酸胍比例为1：3的阻燃涂料。
[Abstract]:With the economic development and progress, people have paid more and more attention to the quality of life, leading to the wide use of interior decoration materials. Because interior decoration materials can provide combustible materials for indoor fire, flame retardant coatings can be used to treat interior decoration materials so as to reduce their combustion performance, which can prevent indoor fires. Pine is the raw material of most interior decoration materials, so it can be used as the experimental base material of flame retardant coatings, combining with halogenation and environmental protection requirements of flame retardant coatings. Therefore, three (2-chloroethyl) phosphate (TCEP) and guanidine carbonate, which are suitable for wood use, were selected. TCEP and guanidine carbonate were prepared into different concentrations of flame-retardant coatings. The pine slices were treated with flame retardant, and then thermogravimetric analysis was carried out. The results of the experiments were used to analyze the merits and demerits of the flame-retardant effects of pine flame-retardant coatings. After many experiments, the TCEP flame retardant coating with concentration of 60% can achieve the best flame retardancy of the pine flame-retardant film, and the temperature at which the maximum heat release rate of the treated pine piece reaches the maximum heat release rate in the process of thermal decomposition has increased by about 90 鈩，
