Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to one and there are high-tensile modified polyphenyl thioether engineering plastics and preparation method thereof.
Background technology
Along with people are more and more higher to the requirement of electronic product portability, electronic product more trends towards thinner, lighter, and require to have higher anti-ly fall, crash-resistant performance.At present in the design and production of electronic product, for reaching preferably frivolous and anti-performance of falling, magnesium alloy, aluminium alloy, the stainless steel and other metal materials of adopting as shell or framework more, but these metallic substance, in batch production, there is the defects such as long, quality is unstable, production technique interruption of production cycle, and metallic substance cost is high, make the price of product higher.Due to these defects of metallic substance, promote to go to study the replaced material of excellent performance, and macromolecular material engineering plastics are main research directions.
Polyphenylene sulfide (Phenylene sulfide, PPS), it has hard and crisp, the feature such as degree of crystallinity is high, difficult combustion, Heat stability is good, electrical property are good, the fields such as electronic industry, mechanical industry, automotive industry and chemical industry are widely used in, as various electric, electronic equipment parts, vehicle arrangement parts, and chemical device parts.But PPS is hard and crisp, degree of crystallinity is high, cause its goods poor toughness, property crisp, physical strength is low, and medium viscosity is unstable etc., and therefore pure PPS resin uses seldom separately, is necessary it to carry out modification.
Polyphenylene oxide (PPO) has good mechanical property, electrical property, weathering resistance etc., but PPO melt viscosity is high, is difficult to independent injection molding, and resistance to dissolubility is poor, has greatly limited its application.
Have at present prior art in PPS, to add PPO to carry out modification, to overcome, PPS is crisp, viscosity is too low, the not resistance to solvent of not easy-formation, and PPO and the excessive shortcoming of melt viscosity, to obtaining the engineering plastics of excellent performance.But the consistency of PPS and PPO is poor, need to add the auxiliary agent such as compatilizer, coupling agent.There are at present some publications to report the modification to PPS, as: Japanese Patent JP3079661 (A) adds PPO, siloxanes in PPS, obtains PPS/PPO alloy; Chinese patent CN1011768359A adds PPO, mineral filler, oxidation inhibitor and compatilizer in PPS, and is combined with glass and obtains PPS modified plastics.But, these patents obtain PPS engineering plastics, all cannot ultra-thin wall thickness (wall thickness≤0.7mm) in the situation that, be met anti-tensile strength of falling requirement, cannot reach the requirement of alternative metals material.
For reaching the portable type electronic products such as smart mobile phone, panel computer, game machine to requirement ultra-thin, shatter-resistant, make up magnalium, aluminium alloy, the stainless steel and other metal materials defect in batch production, need to find one to meet safety energy-conserving environment protection, reduce production costs, have high-tensile engineering plastics.
