摘要

聚丙烯雖具有優異的抗化學藥劑及抗磨蝕性，再加上其能夠有效符合電器與電子產品上之絕緣需求。但聚丙烯本身並不具阻燃的功效，而傳統的無鹵阻燃劑應用，是在聚丙烯中加入金屬氫氧化物，往往為達UL-94 V0的標準，卻加入了過量的阻燃劑，因而導致其複合材料的機械性質下降。有別以往，本研究充分發揮無鹵阻燃劑的協效技術（相乘效應），綜合兩種或兩種以上無鹵阻燃劑之長處，使其性能互補，利用矽烷／水交聯的方式，一方面改善阻燃劑與基材之間的界面，藉以提升其機械性質，另一方面藉由水交聯形成的網狀結構，使基材燃燒時改善其滴垂現象，達到阻燃的效果。在維持機械性質的前提下，開發出符合電子用的無鹵阻燃薄板押出材料，並具有優異的抗彎折特性、優良的電器絕緣特性、優異的抗化學藥劑及抗磨蝕性、防火性能UL-94 V0、輕量化等目標。

Polypropylene (PP) has excellent anti-chemical and anti-scratch properties, and it can meet the requirement of electrical appliance insulates characteristic. However, PP doesn't have the ability of flame retardant, and the traditional halogen free flame retardant was metal hydroxides. These metal hydroxides release a large quantity of water vapor during burning, consequently, retard the further burning of the polymer. However, with a high volume loading, the mechanical properties of these composite become deteriorated. This research aims at using a minor fraction of different halogen free flame retardants, which enhance each other's performance synergistically. Under the premise of good mechanical properties requirements, we developed the halogen free flame retardant PP compounds for sheet extrusion, which have the excellent anti-fold bends characteristic, the good electrical appliance insulates characteristic, excellent anti-chemical and the anti-scratch properties, UL-94 V0 of flame protection performance and lightweight.
