磷酸铝-丙烯酸复合膨胀型防火涂料乳液

Study on Composite Expansion Fireproof Coating with Aluminium Phosphate and Acrylic Acid Emulsion

作为重要的功能涂料，优质防火涂料的研制是目前涂料科学界较为热门的研究课题之一［１～５］．非膨胀型防火涂料只在着火初期可以抑制和延缓火种，一般仅用于防火等级低的场合．而膨胀型防火涂料属发泡型，主要由酸源、碳源和发泡剂等组成，遇火或高温时，在上述３种主要...

The organic inorganic composite expansion fireproof coatings are studied. The experiments showed that the optimal conditions for preparing acrylic acid emulsion are 2% of acrylic acid and 2%to 4% of emulsifier and the reaction temperature at 95 to 100 ℃. The optimal ratio of the aluminium phosphate (61%) emulsion to acrylic acid emulsion is 4 to 1.
