Halogenated resin composition are prepared without using halogen acids by combining at least one silicone intermediate, with an optional silane, an organic halogen-containing ingredient having functional groups selected from the group consisting of hydroxy, amine, and carboxyl groups, and a resin selected from the group consisting of hydroxy- and epoxy-functional resins. One or more amine curing agent and/or catalyst selected from the group consisting of orgalaometallic compounds, acids, bases and mixtures thereof can optionally be added to facilitate ambient temperature curing of the resulting composition. The combined ingredients undergo hydrolysis reactions to form a halogenated organooxysilane that condenses to form a cross-linked halogenated polysiloxane composition. The resin also reacts with the condensing halogenated organooxysilane to introduce itself into the cross-linked halogenated polysiloxane and, thereby forming the halogenated polysiloxane resin composition. The composition is prepared without using an inorganic halogen acid, and is fully-cured at ambient temperature by exposure to atmospheric moisture to form a protective film, or alternatively a composite (10), having improved properties of chemical, abrasion, corrosion, weather, flame, and ultraviolet resistance.
卤化树脂组合物的制备无需使用卤酸,制备方法是将至少一种有机硅中间体与一种任选的硅烷、一种具有选自羟基、胺基和羧基的官能团的有机含卤成分以及一种选自羟基和环氧官能树脂的树脂组合在一起。可选择添加一种或多种胺固化剂和/或催化剂,这些胺固化剂和/或催化剂可选自由加拉金属化合物、酸、碱及其混合物组成的组,以促进所得组合物的常温固化。组合成分发生水解反应,形成卤化有机硅氧烷,并冷凝形成交联卤化聚硅氧烷组合物。树脂也会与缩合的卤化有机硅氧烷发生反应,将自身引入交联的卤化聚硅氧烷中,从而形成卤化聚硅氧烷树脂组合物。该组合物的制备无需使用无机卤酸,在环境温度下暴露于大气湿气中即可完全固化,形成保护膜或复合材料(10),具有更好的耐化学性、耐磨性、耐腐蚀性、耐候性、耐燃性和耐紫外线性。
