抗流失性木材阻燃剂研究(Ⅲ)

STUDY ON LEACH RESISTANCE FLAME RETARDANT FOR WOOD(III)

合成了N-氰基-N′-羟甲基胍(CHMG)、羟甲基脲(HMU)和双羟甲基脉(DHMU).用CHMG或HMU或DHMU和密胺(MA)及磷酸(PA)或磷酸氢二铵(DAP)复配成的阻燃剂水溶液处理了木材,测定了阻燃剂的抗浸提值.

N-cyan-N'-hydroxymethyl guanidine (CHMG),hydroxy-methyl urea (HMV) and dihydroxymethyl urea(DHMU) were synthetized. The wood test samples were treated with an aqueous solution of CHMG or HMU or DHMU and melamine (MA) and phosphoric acid (PA) or diammonium phosphate (DAP). The leach resistance value of the flame retardant was determined.
