    • PROBLEM TO BE SOLVED: To provided an auxiliary flame retardant for imparting high flame-retardant properties to a vinyl chloride resin when used concurrently with a small amount of an antimony trioxide.SOLUTION: The auxiliary flame retardant is produced by combining, at a mass ratio of 1:1 to 4:1, zinc borate having 3.5 HO crystal water, and at least one inorganic microparticle selected from among talc having an average diameter of less than 12 μm, bentonite, dolomite hydroxide and sedimentary rocks. High flame-retardant properties is achieved when the auxiliary flame retardant in an amount of 1-3.1 mass% relative to the total amount is added to a vinyl chloride resin composition comprising a vinyl chloride resin, an antimony trioxide, and a plasticizer.
    • 要解决的问题:提供一种当与少量的三氧化锑同时使用时,对氯乙烯树脂赋予高阻燃性的辅助阻燃剂。

      解决方案:辅助阻燃剂通过以1:1至4:1的质量比组合,具有3.5H 2 O结晶水的硼酸锌,以及 至少一种选自平均粒径小于12μm的滑石中的无机微粒,膨润土,氢氧化白云石和沉积岩。 当将包含氯乙烯树脂,三氧化锑和增塑剂的氯乙烯树脂组合物中相对于总量的1-3.1质量%的量的辅助阻燃剂加入时,可以获得高阻燃性能。 版权所有(C)2012,JPO&INPIT
