  The use of certain prepolymers of 4,4'-methyienebis-(phenyl isocyanate), in place of the latter diisocyanate itself in the preparation of polyurethane-polyureas using aromatic diamine extenders, has a number of advantages par- ticuiariy when the compositions are prepared by reaction injection molding techniques using two streams of reactants. The principal advantages are (i) a useful increase in gel time and (ii) a ratio of amounts of the two reactant streams which more nearly approaches 1:1. This latter factor not only improves the efficiency of mixing of the components in the mixing head but, together with the longer gel time, significantly increases the output of mixed reactants per unit of time. The prepolymers of 4,4'- methyienebis(phenyi isocyanate) employed to achieve the above results are those derived from polyoxy-ethylene polyoxypropylene polyether diols and triols (MW = 1000-10.000), polytetramethylene glycols (MW = 600-5.000) and polyester diols and triols (MW = 500-8.000).

  在使用芳香族二胺扩展剂制备聚氨酯聚脲时，使用 4,4'-亚甲基双（苯基异氰酸酯）的某些预聚物来代替后者的二异氰酸酯本身，具有许多优点，尤其是在使用两股反应物流通过反应注射成型技术制备组合物时。主要优点有：(i) 有效延长凝胶时间；(ii) 两股反应物的比例更接近 1:1。 后一个因素不仅提高了混合头中各组分的混合效率，而且与更长的凝胶时间一起，显著提高了单位时间内混合反应物的产量。为达到上述效果而使用的 4,4'-亚甲基双（苯基异氰酸酯）预聚物是从聚氧乙烯聚氧丙烯聚醚二醇和三醇（分子量＝1000-10.000）、聚四甲基二醇（分子量＝600-5.000）和聚酯二醇和三醇（分子量＝500-8.000）中提取的。

  Polyamide-polyurea containing polymers are disclosed that are derived from the reaction of (A) an organic polyisocyanate: (B) an organic compound having at least two active hydrogen containing groups; and (C) from 15 to 160 parts per 100 parts of said (B) of a chain extender combination comprising (i) a particular enamine and (ii) an aromatic diamine and optionally (iii) an extender diol wherein the ratio of equivalents of (A) to total equivalents of (B) and (C) is within the range of from 0.90:1 to 1.10:1. The polymers find particular utility in the preparation of RIM parts having excellent physical properties. At the same time, the polymers are characterized by slower gel times than prior art aromatic diamine extended polymers thereby allowing the filling of larger molded parts.

  Reaction injection molded polyurea elastomers are disclosed that are derived from the reaction of (1) an aromatic polyisocyanate; (2) primary or secondary amine terminated polyethers; and (3) a novel aromatic amine extender combination comprising (a) an aromatic diamine having at least one of the positions ortho to each amine group substituted by a lower alkyl group and (b) a polymethylene polyphenylamine. The blending of (2) and (3) affords novel polyamine blends which are useful for preparing the polyurea elastomers of this invention. The use of the polymethylene polyphenyl amine com­ponent allows for the retention of the good physical properties of the prior art polyureas while at the same time effecting a cost reduction in the preparation of this useful class of polymers.

  This invention relates to a process for manufacturing a spray urethane elastomer, more particularly to a process for manufacturing a solventless, non-cellular spray urethane elastomer, which comprises spraying a partial prepolymer component having a high molar ratio of NCO/OH prepared from an organic polyisocyanate and from polytetramethylene ether glycol (PTMEG) having a molecular weight of 400 to 2000 and a resin component containing the PTMEG, a specified chain extender and an organobismuth compound catalyst onto a substrate by use of a two components high pressure spray machine. According to the present invention, spraying only of the stock solutions by use of the two components high pressure spray machine accomplishes coating and the stock solutions are cured in one second to ten and several seconds after being sprayed without producing cells even when thick-coated. Therefore, the present invention makes it possible to effect wet-on-wet coating within a short period of time, resulting in making it possible to accomplish a coating having a predetermined thickness in a short period of time. An elastomer, which has been coated, is excellent at modulus, tensile strength, elongation, tear strength, heat resistance, and the like, such as pipe, tank and the like, waterproof materials such as concrete for the roof and outside wall which need waterproofness, thick-coated protective coating for a thermal insulant such as rigid polyurethane foam, polystyrene foam, board or the like, seamless floor covering material, open mold molding by use of a mold made of metal or resin, and the like.

  本发明涉及一种制造喷涂聚氨酯弹性体的工艺，特别是一种制造无溶剂、非细胞喷涂聚氨酯弹性体的工艺、该工艺包括使用双组分高压喷涂机，将由有机多异氰酸酯和分子量为 400 至 2000 的聚四亚甲基醚二醇（PTMEG）制备的具有高 NCO/OH 摩尔比的部分预聚物组分，以及含有 PTMEG、特定扩链剂和有机铋化合物催化剂的树脂组分喷涂到基材上。 根据本发明，使用双组分高压喷涂机仅喷涂浆料溶液即可完成涂层，而且浆料溶液在喷涂后一秒至十秒和数秒内固化，即使厚涂层也不会产生细胞。因此，本发明可以在短时间内实现湿对湿涂层，从而可以在短时间内完成具有预定厚度的涂层。 涂覆后的弹性体在模量、拉伸强度、伸长率、撕裂强度、耐热性等方面都非常出色，例如管道、水箱等，需要防水的屋顶和外墙混凝土等防水材料，硬质聚氨酯泡沫、聚苯乙烯泡沫、板等隔热材料的厚涂保护层，无缝地板覆盖材料，使用金属或树脂制成的模具进行开模成型等。
