為能夠增加高分子材料耐燃性的物質(zhì)，主要用于高分子材料如塑料，橡膠、纖維等，而這些材料大多數(shù)是可以燃燒的。特別是塑料，要將其應(yīng)用在交通運(yùn)輸、建筑、電工器材、航空、宇宙飛行等方面，就迫切需要解決其耐燃燒問題。阻燃劑的使用一般應(yīng)具備以下幾個(gè)條件：不降低高分子材料的物性，如耐熱性、機(jī)械強(qiáng)度、電氣性能;分解溫度不應(yīng)太高，但在加工溫度下又不能分解;耐久性好;耐候性好;價(jià)廉。一般來講有機(jī)阻燃具有很好的親和力，在塑料中，溴系阻燃劑在有機(jī)阻燃體系中占據(jù)ji優(yōu)勢，雖然在環(huán)保問題上“非議”多端但一直難以有其他阻燃劑體系取代。

TCEP、TCPP、TDCP和V-6)主要用于聚氨酯泡沫。針對TCEP的歐盟風(fēng)險(xiǎn)評估已經(jīng)完成，有待公布；針對TCPP、TDCP以及V-6的風(fēng)險(xiǎn)評估人類健康與環(huán)境部分仍在進(jìn)行中。同時(shí)，也在進(jìn)行更多測試以及數(shù)據(jù)收集工作。其中一些風(fēng)險(xiǎn)評估有望在2006年完成，而其他評估則會(huì)在2007年完成。Sb2O3主要用作為鹵化阻燃劑或彈性體的一種增效劑。歐盟風(fēng)險(xiǎn)評估的人類健康與環(huán)境部分仍在進(jìn)行中。有關(guān)人類健康部分的新討論在2006年6月進(jìn)行，環(huán)境部分有望在年底前完成。[1]阻燃組成編輯在非鹵素阻燃劑中紅磷是一種較好的阻燃劑，具有添加量少、阻燃效率高、低煙阻燃、低毒、用途大范圍等優(yōu)點(diǎn)。紅磷與氫氧化鋁、膨脹性石墨等無機(jī)阻燃劑復(fù)配使用，制成復(fù)合型磷/鎂、磷/鋁、磷/石墨等非鹵阻燃劑，可使用阻燃劑量大幅降低，從而改善塑料制品的加工性能和物理機(jī)械性能。但普通紅磷在空氣中易氧化、吸濕，容易引起粉塵，運(yùn)輸困難，與高分子材料相溶性差等缺點(diǎn)，應(yīng)用范圍受到了限制。為彌補(bǔ)這方面不足，以擴(kuò)大紅磷應(yīng)用范圍，我們采用了國外微膠囊包覆工藝，使之成為微膠囊化紅磷。微膠囊化紅磷除克服了紅磷固有的弊端外，并具有效率高、低煙，在加工中不產(chǎn)生youdu氣體。</p><p> 7.低發(fā)煙、低duhai氣體技術(shù)目前對于降低有害氣體的研究成果不多。甩CaCO3減少PVC釋放HCL量的方法已在實(shí)際中應(yīng)用，同樣對氯丁橡膠降低氯害也有應(yīng)用。還有采用Al(OH)3吸收HDPE燃燒時(shí)放出有害氣體技術(shù)。今后技術(shù)開發(fā)的重點(diǎn)是吸收氨氣、**氫等氣體。8.聚合磷酸酯及鹵系阻燃劑隨著我國聚氨酯工業(yè)的迅速發(fā)展，聚氨酯阻燃劑品種和產(chǎn)量都相應(yīng)迅速增長。杭州大學(xué)開發(fā)的三(β—氯乙基)磷酸酯聚合體應(yīng)用于聚氨酯泡沫具有較好的阻燃性能的抗遷移性。化工部黎明化工研究院開發(fā)的聚合磷酸酯阻燃劑類似于國外目前應(yīng)用較為理想的阻燃劑Olin101和CR—505，因此，該產(chǎn)品是國內(nèi)目前**理想的聚氨髓燃劑。另外，還有三(2,3—二氯丙基)磷酸酯的研制。由于鹵系阻燃劑阻燃性能好，價(jià)格低廉，所以盡管國外目前開發(fā)非鹵型阻燃劑的呼聲很高，但對于我國而言，仍有進(jìn)一步開發(fā)的必要。在含氯阻燃劑中，氯化石蠟—70是近幾年開發(fā)的較好的產(chǎn)品。沈陽化工廠、上海電化廠等單位已有生產(chǎn)，主要用于聚烯烴、合成橡膠等；含溴阻燃劑近年來研究出的品種較多，產(chǎn)量也較大，是我國阻燃產(chǎn)品中發(fā)展**快的一類。新產(chǎn)品有六溴環(huán)十二烷，三(2，3—二溴丙基)異氰酸酯、十溴聯(lián)苯醚、四溴丁烷、五溴甲苯等。鹵素中，溴的阻燃作用比氯大。</p><div

非鹵系阻燃劑磷系阻燃劑磷系分為有機(jī)和無機(jī)磷系阻燃劑。有機(jī)磷系包括磷酸酯、磷雜菲、磷腈、有機(jī)次磷酸以及有機(jī)次磷酸鹽化合物等；無機(jī)磷系阻燃劑包括聚磷酸銨、三聚氰胺磷酸鹽、三聚氰胺聚磷酸鹽等。近年來磷酸酯化合物發(fā)展十分迅速，品種有雙酚A雙（二苯基）磷酸酯（BDP）、間苯二酚雙（二苯基）磷酸酯（RDP）、甲基磷酸二甲酯（DMMP）等，還有傳統(tǒng)的磷酸三本酯（TPP）、磷酸三（氯異丙基）酯（TCPP）、磷酸三（β-氯乙基）酯（TCEP）等。采用BDP阻燃PC/ABS合金，15%的BDP阻燃該合金，體系的LOI達(dá)到，UL94V-0級，Av-HRR（平均燃燒熱）、pk-HRR（熱釋放速率的峰值）分別下降；采用BDP/納米SiO2復(fù)配阻燃PC/ABS，當(dāng)納米SiO2的添加量為8%時(shí)，Av-HRR(平均燃燒熱)、pk-HRR(熱釋放速率的峰值)分別下降，阻燃、抑煙效果比較好，對合金的力學(xué)性能影響**小。采用RDP阻燃PC/ABS合金。PC/ABS的比例為70:30，當(dāng)RDP的添加量為14%時(shí)，可明顯提高合金的阻燃性能，阻燃級別達(dá)UL94V-0，且對合金的拉伸強(qiáng)度與斷裂伸長率影響不大。溴系、磷系、溴-磷系均適合于PC/ABS共混體。BPC（含溴碳酸酯齊聚物）、TPP（三苯基磷酸酯）、TDBPPE[三（二溴苯基）磷酸酯]、TCP。有機(jī)氮系阻燃劑如三嗪及其衍生物、三聚氰胺等單獨(dú)使用時(shí)效果不理想。pvc阻燃劑公司</p><p
