Description
Technical field
The present invention relates to field of new, especially relate to a kind of ppe based composites.
Background technology
Ppe (Polyphenylene oxide) is called for short PPO, is a kind of good comprehensive properties engineering plastics; Have good physical and mechanical properties, thermotolerance and electric insulating quality, creep resistant is the most excellent in all thermoplastic engineering plastics under the high temperature, and has excellent acid, alkaline-resisting, chemical proofing; Stability to hydrolysis is fabulous; Molding shrinkage and thermal expansivity are little, and dimensional stability is good, and goods use its stable performance repeatedly in HP steam.PPO has been widely used in aspects such as electronic apparatus, automobile, household electrical appliance, office equipment and industrial machinery.As special engineering plastics, though polyphenylene sulfide has above-mentioned excellent properties since its still exist such as poor solvent resistance, goods stress cracking takes place easily, notched Izod impact strength is low, melt viscosity is high, weak points such as processing forming difference.
Because above-mentioned defective and the cost factor of PPO, the modification of PPO is become the focus of domestic and international research, its main means have fiber reinforcement PPO, particles filled MODIFIED PP O and with polymer blending etc., and are specific as follows:
(1) fiber reinforcement PPO matrix material
Fiber commonly used has spun glass (GF) and thomel (CF), can reach the intensity, rigidity and the stable on heating purpose that improve material, and conventional working methods such as technology is simple, extrudes, mold pressing, injection moulding all are suitable for.But each that use that fiber carries out can increasing when performance strengthens material to PPO makes physics, the chemical property of matrix material on the crystal different directions differ bigger to abnormal shape.Whisker (Whisker) is MOX or the salt with certain length-to-diameter ratio (general L/D＞20); Be different from general powder filler; Its fibrous microtexture makes it as filler filled high polymer material the time; Intensity effect with significant strongthener, and the big defective of material anisotropy can overcome fibre reinforced composites the time.
Prior art shows: the adding of fiber (or whisker) makes the thermomechanical property of PPO improve, and mechanical property is enhanced, and the tensile strength and the flexural strength of matrix material all are improved.
(2) particles filled MODIFIED PP O
The exploitation of polymer/inorganic filler composite materials; Be the cost of hoping on the basis that guarantees material property, to reduce material at first; Yet, through the development of decades, after especially nanotechnology produces; The polymer/inorganic filler composite materials has not only been realized the purpose that reduces cost, and the adding of mineral filler can also improve performances such as the rigidity, thermotolerance, enhancing, plasticising of matrix material, toughness reinforcing and electroconductibility.But consistency is relatively poor between inorganics and the macromolecular polymer, is difficult to guarantee nanoparticle homodisperse therein, thereby the reinforced effects of material property is had a greatly reduced quality.
(3) PPO and polymer blending modification
In recent years, people utilize PS (PS), high-impact polystyrene (HIPS), polyamide (PA), polybutylene terephthalate (PBT), polyphenylene sulfide (PPS) to wait PPO is carried out the research of modification many.
The PPO/PS composite study is found that the PPO/PS alloy can keep the good characteristic of pure PPO, and its flowability improves; After HIPS added PPO, the notched Izod impact strength of material increased but is no more than 15KJ/m
2PPO/PA (polymeric amide), PPO/PBT (polybutylene terephthalate), PPO/PPS (polyphenylene sulfide) matrix material have improved thermotolerance, oil-proofness and the solvent resistance of PPO.
Modified effect is with to add the polymer property degree of correlation big, and when polymkeric substance and PPO are complete perhaps complete mutually when incompatible, modified effect is not satisfactory.
To sum up, the existing reinforced composite that also need study PPO, so that this matrix material has more excellent abrasive, thermotolerance and supporting capacity (the PV ultimate value is high), preparation technology is simple, price is lower.
