Title:
PPS ENGINEERING PLASTIC USED FOR NMT, AND PREPARATION METHOD FOR PPS ENGINEERING PLASTIC
Document Type and Number:
WIPO Patent Application WO/2016/179771
Kind Code:
A1
Abstract:
Provided are a PPS engineering plastic used for NMT, and a preparation method for the PPS engineering plastic. The PPS engineering plastic is mainly prepared from the following raw materials, calculated according to parts by mass: 50-80 parts of a PPS resin, 10-45 parts of glass fibres, 3-15 parts of a toughening agent, 0.3-3 parts of an antioxidant, 0.3-2 parts of a heat stabiliser, 0.5-3 parts of a lubricant, 0-3 parts of a nucleating agent, and 0-5 parts of a colourant. The toughening agent is an unsaturated epoxy copolymer, an optional styrenic thermoplastic elastomer, and an optional anhydride-modified styrenic thermoplastic elastomer, wherein the unsaturated epoxy copolymer is more than 20% of the total mass of the toughening agent. The present invention improves the toughness, polarity, processing fluidity and wettability of the PPS resin, increases the impact resistance of the PPS engineering plastic and the adhesive force with a metal material, and satisfies NMT process requirements.
