【摘要】：隨著經(jīng)濟的發(fā)展與進步,人們已經(jīng)越來越重視生活的品質(zhì),導(dǎo)致了內(nèi)裝飾材料的廣泛的使用。由于內(nèi)裝飾材料會為室內(nèi)火災(zāi)發(fā)生提供可燃物,因此對內(nèi)裝飾材料用阻燃涂料進行阻燃處理從而降低其燃燒性能,可以起到預(yù)防室內(nèi)火災(zāi)的作用。松木是大多數(shù)內(nèi)裝飾材料的原材料,因此可以作為阻燃涂料的實驗基材使用,再結(jié)合阻燃涂料無鹵化以及環(huán)保的要求,因而選用適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。將TCEP以及碳酸胍分別配制成不同濃度的阻燃涂料,對松木片進行阻燃處理,然后對經(jīng)過阻燃處理的松木片進行熱重分析,通過實驗結(jié)果數(shù)據(jù)分析各自的阻燃效果的優(yōu)劣,在多次實驗后,得到濃度為60%的TCEP阻燃涂料使松木片的阻燃性能達到最佳,經(jīng)過其處理的松木片在熱分解過程中到達最大熱釋放速率的溫度提高了90℃左右,最終殘余量由原來的20%提升至63%；而使松木片阻燃性能達到最佳阻燃效果的碳酸胍阻燃涂料的使用濃度為70%,經(jīng)過其處理的松木片在熱分解過程中到達最大熱釋放速率的溫度提高了85℃左右,最終殘余量由原來的20%提升至58%。阻燃涂料的協(xié)同作用研究是今后阻燃涂料運用的重要方向,而磷系和氮系阻燃涂料在理論上又有很好的協(xié)同效應(yīng),因此將TCEP與碳酸胍進行不同比例的配比,分別配制成濃度為70%和60%的混合阻燃涂料,依次對松木片進行阻燃處理,然后進行熱重分析,實驗結(jié)果發(fā)現(xiàn)濃度為70%進行協(xié)同阻燃時,TCEP與碳酸胍的最佳比例為1：3,經(jīng)其處理的松木最終殘余量為66%,最大熱釋放速率時的溫度提高至379℃左右；而濃度為60%進行協(xié)同阻燃時,TCEP與碳酸胍的最佳比例則為3：1,經(jīng)其處理的松木片最終殘余量為65%,最大熱釋放速率時的溫度提高到375℃左右。然后對這兩種處理過的松木片進行氧指數(shù)測試,發(fā)現(xiàn)濃度為70%并且TCEP與碳酸胍比例為1：3時松木片的氧指數(shù)較高,因而,松木片阻燃效果最好的方法為使用濃度為70%且TCEP與碳酸胍比例為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，
