Description
Technical field
The present invention relates to a kind of Noryl masterbatch, belong to engineering plastics technical field.
Background technology
Polyphenylene oxide belongs to one of five large-engineering plastics, this polymer absorption rate is low, saturated water absorption < 0.1% under room temperature, and resistance to combustion is from putting out, there is good mechanical property and electrical property in wide temperature range, under high temperature, resistance to creep is fabulous, have the performance of excellent acid-and base-resisting, salt solution and heat-proof water, but its melt temperature is high, melt viscosity is large, thermoplasticity is poor, and solvent resistance is poor, and therefore its application is greatly limited.
The use of polyphenylene oxide relies on modification mostly, if State Intellectual Property Office's publication number disclosed in the 17 days April in 2013 is CN103044894A, name is called the patent of invention of " a kind of modified polyphenyl ether composition ", and composition disclosed in this patent is containing following component: polyphenylene oxide 100 weight part; High-impact polystyrene 12-30 weight part; Hydrogenated styrene block copolymers 12-30 weight part; Chopped glass fiber 16-40 weight part; Compatilizer 6-10 weight part; Oxidation inhibitor 1-3 weight part; Organophosphate ester flame retardant 12-30 weight part; Organic silicon fibre retardant 1-10 weight part; Clay 1-5 weight part.
And for example State Intellectual Property Office's publication number disclosed in the 20 days March in 2013 is CN102977583A, the patent of invention that name is called " Noryl and prepare the method for base material based on Noryl ", Noryl disclosed in this patent, component comprises by weight: methyl bromide PPO 5-100 part, aluminium hydroxide 0-50 part and solvent 0-40 part.Although this patent also can realize the modification of polyphenylene oxide, need to mix under solvent condition, production environment is clean not, and cost is higher.
Summary of the invention
