This invention relates to novel flame retardants (FR) resulting from the reaction of (a) or (b) with (c) where (a) is a compound containing at least one amine group and with at least one sixteenth of the amine molecules having at least one methylol bond, (b) is a phenol with at least one sixteenth of the phenol molecules having at least one methylol bond, and (c) is a mineral acid, organic acid, and organo-phosphorous acid, or a mixture thereof and optionally adding a polyhydric compound and/or optionally adding formaldehyde to the acid. These compositions are for use in general flame retardant applications such as coatings, adhesives, and articles made of polymeric materials. The FR mechanism by which these compounds generally perform as an FR agent is intumescence but the field of this invention is not restricted to that mechanism. Some of the compounds have substantial intumescence and others have very little intumescence but still are flame retardants.
本发明涉及一种新型阻燃剂(FR),其由(a)或(b)与(c)反应而成,其中(a)是一种含有至少一个胺基的化合物,其中至少有十六分之一的胺分子具有至少一个甲醛键,(b)是一种酚,其中至少有十六分之一的酚分子具有至少一个甲醛键,(c)是矿酸、有机酸和有机磷酸或其混合物,可选择添加多元醇化合物和/或可选择添加甲醛到酸中。这些组合物可用于一般阻燃应用,如涂料、粘合剂和由聚合材料制成的物品。这些化合物通常作为阻燃剂的机理是膨胀,但本发明的领域并不限于该机理。其中一些化合物具有显著的膨胀性,而其他化合物则几乎没有膨胀性,但仍然是阻燃剂。
