Description
Technical field
The present invention relates to materials processing technology field, specially a kind of POK, TLCP, PET trielement composite material and its preparation
Technique.
Background technique
Polyketone (POK) is current wearability model engineering plastic most outstanding, and wearability is 14 times of POM, abrasion loss pole
It is low, it is high that dimensional stability is used for a long time, and influenced by temperature change very small, low noise effect is prominent, with excellent water-fast
Solve performance, no matter in cold water or hot water, mechanical performance variation it is much smaller compared to nylon, polyester etc., substantially with PPO and
PPS is suitable, can use for a long time in water environment；Due to its close crystalline texture, all very to the barriering effects of various substances
Excellent, oleophylic, not hydrophilic, and resistance to various chemical solvents, barrier property is substantially suitable with EVOH, and can pass through and squeeze out, be molded,
The different process such as blow molding form all kinds of barrier products.
LCP plastic material full name, Chinese liquid crystal polymer, including TLCP and LLCP, it is a kind of novel high score
Sub- material, liquid crystal liquid crystal property is generally presented in molten state, and this kind of material has excellent heat resistance and moulding processability, polymerization
For method based on melt polycondensation, all aromatic LCP is aided with solid phase polycondensation so that high molecular weight products, non-all aromatic LCP is made more
Plastic material produces product frequently with a step or two step melt polymerizations, and the technology that high molecular weight LCP is produced in continuous fusion polycondensation obtains
To development, tensile strength and bending modulus can be more than the various thermoplastic engineering plastics to grow up, mechanical performance, dimensionally stable
Property, optical property, electrical property, chemical resistance, anti-flammability, processability are good, and heat-resist, thermal expansion coefficient is lower.
Pet resin (PET) have excellent electrical property, mechanical property, heat resistance and compared with
Low production cost is widely used in the fields such as electronic apparatus, machinery, auto parts and components, but there are crystallization rates for PET resin
Slowly, the disadvantages of moulded products shrinking percentage is big, poor dimensional stability and matter itself are crisp, seriously limits it as engineering plastics
Using being the hot spot of research at present to the high performance of PET, improved method, which concentrates on, is added crystallization nucleating agent or crystallization promotees
It is compound into agent and glass fibre, or certain fire retardant is added, fiberglass reinforced PET or flame-retardant strengthening polythylene terephthalate (PET) is made, in addition PET
Alloying is also the emphasis of research.
Wherein, polyethylene terephthalate is hypocrystalline blend, and physicochemical property is poor, in the process of injection molding
In, when demoulding because PET is not crystallized completely occur sticking to mould, it is difficult the bad phenomenon such as demould, rise so that product made from last
The bad problems such as insufficient formability, heat resistance are low, processing performance is low.Therefore need to add a large amount of compatilizer or toughener to mention
High combination property rises cost of manufacture, and the performances such as impact strength, toughness, heat resistance, processing performance are lower, fails full
The foot requirement of the fields to its physicochemical property such as electronic apparatus, office equipment now.
Summary of the invention
