Title:
HYPERBRANCHED RESIN-TOUGHENED PPS ENGINEERING PLASTIC, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/179772
Kind Code:
A1
Abstract:
A hyperbranched resin-toughened PPS engineering plastic, and a preparation method therefor. The PPS engineering plastic is mainly prepared from the following raw materials, calculated according to parts by mass: 50 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 a hyperbranched resin, an optional styrenic thermoplastic elastomer, and an optional anhydride-modified styrenic thermoplastic elastomer, wherein the hyperbranched resin is more than 20% of the total mass of the toughening agent. The PPS engineering plastic not only improves toughness and impact resistance, but also increases the adhesive force with a metal material, and satisfies NMT process requirements. In addition, optimisation processing is performed on the amounts of the various components, further improving the mechanical properties and the heat resistance of the PPS engineering plastic.
