(ZH) 一种聚氨酯防水涂料及其制备方法和应用
Abstract
(EN) Disclosed are a polyurethane waterproof coating, a preparation method therefor and the use thereof. The polyurethane waterproof coating comprises a polyurethane prepolymer and an auxiliary agent, wherein the raw material of the polyurethane prepolymer comprises a polyol, an isocyanate and a secondary amine compound, wherein the secondary amine compound is selected from one or a combination of more of the compounds represented by formula (I): wherein R1 is a branched chain alkylene, R2 is H or a C1-10 alkyl, or a C1-10 alkyl substituted by one or more of a C1-6 alkyl and a C1-6 alkoxy, or a phenyl; the polyurethane prepolymer is prepared by mixing the polyol, the secondary amine compound and part of the isocyanate for a reaction, and then adding the rest of the isocyanate for a futher reaction; and the waterproof coating of the present invention is suitable for machine spraying onto a high-temperature base layer, can combine the sagging resistance and viscosity balance, and is especially suitable for spraying construction on a base layer with a temperature of 50ºC or more.
(FR) Sont divulgués un revêtement de polyuréthane imperméable à l'eau, son procédé de préparation et son utilisation. Le revêtement de polyuréthane imperméable à l'eau comprend un prépolymère de polyuréthane et un agent auxiliaire, la matière première du prépolymère de polyuréthane comprenant un polyol, un isocyanate et un composé amine secondaire, le composé amine secondaire étant choisi parmi l'un ou une combinaison de plusieurs des composés représentés par la formule (I) : dans laquelle R1 représente un alkylène à chaîne ramifiée, R2 représente H ou un groupe alkyle en C1-10, ou un alkyle en C1-10 substitué par un ou plusieurs parmi un alkyle en C1-6 et un alcoxy en C1-6, ou un phényle ; le prépolymère de polyuréthane est préparé en mélangeant le polyol, le composé amine secondaire et une partie de l'isocyanate pour une réaction, et en ajoutant ensuite le reste de l'isocyanate pour une autre réaction ; et le revêtement imperméable à l'eau selon la présente invention est approprié pour une pulvérisation par machine sur une couche de base à haute température, peut combiner la résistance à l'affaissement et l'équilibre de viscosité, et est particulièrement approprié pour une construction par pulvérisation sur une couche de base avec une température supérieure ou égale à 50 °C.
(ZH) 本发明公开了一种聚氨酯防水涂料及其制备方法和应用,该聚氨酯防水涂料包括聚氨酯预聚体和助剂,聚氨酯预聚体的原料包括多元醇、异氰酸酯和仲胺化合物,所述仲胺化合物为选自式(Ⅰ)所示化合物中的一种或多种的组合:(I) R1为支链亚烷基;R2为H或C1-10烷基,或为被选自C1-6烷基、C1-6烷氧基中的一个或多个所取代的C1-10烷基或苯基;聚氨酯预聚体通过使多元醇、仲胺化合物和部分异氰酸酯混合反应后再加入剩余异氰酸酯再次反应而制成;本发明防水涂料适于在高温基层上进行机器喷涂且能够兼顾抗流挂性和粘度平衡,尤其适于在温度达到50℃以上的基层上进行喷涂施工。
