采用三聚氰胺、磷酸(多聚磷酸)為原料經反應生成磷酸三聚氰胺鹽(PM)及聚磷酸三聚氰胺鹽 (PPM) 后, 繼續添加硼酸(硼砂)反應生成磷酸三聚氰胺硼酸 (硼砂) 鹽 (PMB、PMBNa)及聚磷

摘要:采用三聚氰胺、磷酸(多聚磷酸)為原料經反應生成磷酸三聚氰胺鹽(PM)及聚磷酸三聚氰胺鹽 (PPM) 后, 繼續添加硼酸(硼砂)反應生成磷酸三聚氰胺硼酸 (硼砂) 鹽 (PMB、PMBNa)及聚磷酸三聚氰胺硼酸(硼砂)鹽(PPMB、PPMBNa),用傅立葉紅外表征、熱重分析(TGA)、氧指數、力學性能測試對其進行了分析和表征,并研究其阻燃性能。對于材料的選擇、各成分的用量和制備進行了研究。結果表明,PM 及 PPM 的最佳合成條件為 n(H3PO4):n(C3H6N6) = 2:1及 n(H5P4O13):n(C3H6N6) = 4:1;PMB與 PMBNa 的最佳合成條件為n(PM):n(H3BO3) = 1:1.5及 n(PM):n(Na2B4O7) = 1:0.1;PPMB與 PPMBNa 的最佳合成條件為 n(PPM):n(H3BO3) =1:3及 n(PM):n(Na2B4O7)=1:1。氧指數測試中,PPMBNa的氧指數比其他產物較高。 在力學性能測試中, 阻燃劑的添加降低了聚丙烯的抗拉伸強度。  35967

Synthesis and Characterization of a New Type of Flame Retardants Containing Nitrogen, Phosphorus and Boron Elements
Abstract: Using melamine and phosphoric acid, poly phosphoric acid, boric acid and borax as reagents to form phosphoric melamine  and  poly phosphoric melamine ,  then continue to add boric acid (borax) to form a melamine phosphate acid (borax) (PMB, PMBNa) and melamine polyphosphate boric acid (borax) (PPMB, PPMBNa),the structure and performance of product was characterized by IR、TGA  、DSC and oxygen index, and discuss its Flame retardant . For the choice of materials, the amount of each ingredient and the preparation were studied. The results show  that the optimum conditions for PM and PPM was n (H3PO4): n (C3H6N6) = 2: 1 and n (H5P4O13): n (C3H6N6) = 4: 1; the optimum conditions for PMB and PMBNa was n (PM): n (H3BO3) = 1: 1.5 and n (PM): n (Na2B4O7) = 1: 0.1; the optimum conditions for PPMB and PPMBNa of n (PPM): n ((H3BO3) = 1: 3 and n (PM): n (Na2B4O7) = 1: 1. By oxygen index test, oxygen index of PPMBNa is higher than other products. In the mechanical test, adding the flame retardant reduces the tensile strength of polypropylene.
