Description
Technical field
The invention belongs to technical field of polymer materials, relate to a kind of Noryl (MPPO) material and preparation method thereof.
Background technology
Along with social progress, the development of science and technology, people's life is more and more convenient, and people are also more and more higher to the attention rate of environment simultaneously.Polyphenylene oxide (PPO) is a kind of thermoplastic engineering plastic of excellent performance, has that density is little, nontoxic, creep resistance is good, molding shrinkage is low, second-order transition temperature (T
g) height, the advantages such as good electrical property.Wherein high creep resistance can be its most outstanding feature, and therefore PPO is particularly suitable for making the industrial structural part that bears long-duration load.But PPO also has some shortcomings, as poor solvent resistance, goods, that stress cracking, notched Izod impact strength easily occur is low etc.PPO photostabilization is poor, uses product easy to change for a long time under sunlight or luminescent lamp, color jaundice, and reason is that ultraviolet ray can make due to the chain combination division of aromatic oxide; The fatal shortcoming of another one is poor fluidity, forming process difficulty, and because PPO molecular chain rigidity is larger, melt viscosity is high, and this has affected applying of PPO.
HIPS resin has good physicals, good with PPO consistency, can improve the processing characteristics of PPO, and small on the excellent properties impact of PPO itself.Given the better toughness of PPO elastomeric adding, and greatly improved the shock strength of material, PPO can be modified as to elastomerics, is applied to the occasions such as electric wire.
Summary of the invention
The object of the invention is to that the notched Izod impact strength that PPO in prior art exists is low in order to overcome, poor solvent resistance, price provide a kind of super tough Noryl (MPPO) material compared with the defect existing in high prior art, this material has the higher advantage such as shock strength, good weatherability.
