Abstract

The invention relates to a polyphenyl ether elastomer composition and a preparation method thereof. The composition comprises the following components in percentage by mass: 3 to 40 percent of polyphenyl ether, 25 to 50 percent of styrene block polymer resin, 15 to 50 percent of rubber processing oil, 0 to 40 percent of polyolefin, 0 to 20 percent of inorganic mineral filler and 0.1 to 0.3 percent of antioxidant. The preparation method comprises the following steps of: weighing the materials in a mass ratio, mixing the materials at a high speed in a high-speed mixer, putting the mixture into a double-screw extruder, and performing melt extrusion and granulation to obtain the polyphenyl ether elastomer composition. Compared with the prior art, the polyphenyl ether elastomer composition hasthe advantages of softness, high heat resistance and the like.

Description

technical field [0001] The invention relates to a composition in the polymer field and a preparation method thereof, in particular to a polyphenylene ether elastomer composition and a preparation method thereof. Background technique [0002] The thermoplastic elastomer composition has the soft elasticity of rubber at normal temperature, and can be processed or recycled at will like thermoplastics at a temperature higher than its melting point or softening point. There are many types of thermoplastic elastomers, among which styrene thermoplastic elastomers (or styrene block copolymers) are the most widely used type of elastomers, which use glassy polystyrene as the hard segment and rubbery Polybutadiene or isoprene is a block copolymer composed of soft segments, because of its excellent resilience and surface feel, excellent weather resistance, ozone resistance, cold resistance, recyclability and product safety Due to a series of advantages such as flexibility and adjustabil...
