表面能低、惰性及低极性是聚丙烯难以被附着的重要原因。选择附着树脂对聚丙烯表面改性有助于涂料润湿和附着成膜。附着树脂主要包括聚烯烃类、有机硼引发类、端叠氮基芳香聚合物等。聚烯烃类附着树脂一种是聚丙烯的氯化物或马来酸酐接枝物,以及它们的再功能化扩链产品,另一种是其他聚烯烃的接枝物。有机硼和端叠氮基芳香聚合物是原位化学接枝的附着树脂新类型,拓展了聚烯烃类的适用温度和适用环境。
錶麵能低、惰性及低極性是聚丙烯難以被附著的重要原因。選擇附著樹脂對聚丙烯錶麵改性有助于塗料潤濕和附著成膜。附著樹脂主要包括聚烯烴類、有機硼引髮類、耑疊氮基芳香聚閤物等。聚烯烴類附著樹脂一種是聚丙烯的氯化物或馬來痠酐接枝物,以及它們的再功能化擴鏈產品,另一種是其他聚烯烴的接枝物。有機硼和耑疊氮基芳香聚閤物是原位化學接枝的附著樹脂新類型,拓展瞭聚烯烴類的適用溫度和適用環境。

Because of the low surface energy, inertness and low polarity of polypropylene, it is diffi cult for coatings to adhere to the surface of it. So we select adhesion resin to modify the polypropylene, helping coatings wet the surface of polypropylene and adhere to it. The modifying resins include polyolef in, organic boron initiated resin and azide group terminated aromatic polymer. Polyolefi n resins include the chloride of polypropylene, graft polymer of maleic anhydride, or chain extending product of them, and other one is graft polymer of other polyolefin resin. Organic boron initiated resin and azide group terminated aromatic polymer belong to the in-situ chemical grafting resin used as a new type of adhesion resin, expanding the applicable temperature and environment of polyolefi n.
