Abstract
A kind of plastic alloy material resistant to high temperature, including the following raw material in percentage by weight: PEEK 60%-80%, PA46 15%-40%, silicone powder 1%-3%.Have many advantages, such as that high temperature resistant, good toughness, cost performance are high.
Description
Technical field
The invention belongs to polymeric material fields, and in particular to a kind of plastic alloy material resistant to high temperature is mainly used in
Nuclear energy power generation field components.
Background technique
Polyether-ether-ketone (PEEK) resin is a kind of special engineering plastics haveing excellent performance, compared with other special engineering plastics
With more significant advantages, resistance to 260 degree of positive high temperature, mechanical performance is excellent, self-lubrication is good, chemicals-resistant burn into is fire-retardant, resistance to stripping
From property, wear-resisting, intolerant to strong nitric acid, the concentrated sulfuric acid, anti-radiation, superpower mechanical performance can be used for the sections such as high-end machinery and aviation
Skill.It is specific as follows:
Heat-resisting quantity --- glass transition temperature (Tg=143 DEG C) with higher and fusing point (Tm=334 DEG C) loads thermal change
Shape temperature is up to 316 DEG C, and long-term use temperature is 260 DEG C, instantaneously using temperature up to 300 DEG C.
Mechanical property --- there is rigidity and flexibility, it is especially very prominent to the fatigue resistance under alternate stress, it can be with alloy
Material compares favourably.
Self-lubrication --- there are excellent sliding properties, be suitable for being strict with the field of low-friction coefficient and abrasion performance purposes
It closes, especially the PEEK wearability with carbon fiber, graphite, the PTFE modified sliding trade mark is very superior.
Corrosion resistance --- outside the concentrated sulfuric acid, PEEK does not dissolve in any solvent and strong acid, highly basic, and hydrolysis, has very high
Chemical stability.
Anti-flammability --- there is self-extinguishment can reach the 94V-0 grade of UL standard even if any fire retardant is not added.
Workability --- since PEEK has temperature flowing good, and the very high feature of thermal decomposition temperature, it can be used a variety of
Processing method: injection moulding, extrusion molding, compression molding and melt spinning etc..
Electrical property --- electrical insulation capability is very excellent, and volume resistivity is about 1016Ω·cm.It still has in high-frequency range
There are lesser dielectric constant and dielectric loss.
Although PEEK has many advantages, such as, PEEK prepares the disadvantages of difficult, expensive, product brittleness is big.
Nylon 46 (PA46) is a kind of novel polyamide resin with high-melting-point and high-crystallinity, and fusing point is high
Up to 295 DEG C, long-term use temperature 5000hours) (CUT is up to 163 DEG C.Price is well below PEEK resin, and toughness
It is better than PEEK resin, has and high-temperature resin, such as LCP, PPS and PEEK performance having the same.
PEEK and PA46 are combined with each other, a kind of plastic alloy material resistant to high temperature is prepared, improves the price of PEEK
The disadvantages of height, poor toughness.
Summary of the invention
The object of the invention is to solve PEEK poor toughness, the disadvantages of price is high, a kind of plastic alloy resistant to high temperature is provided
Material, the material have many advantages, such as that high temperature resistant, cost performance are good.
In order to solve the above technical problems, the technical solution adopted by the present invention is as described below:
A kind of plastic alloy material resistant to high temperature, including the following raw material in percentage by weight: PEEK 60%-80%, PA46
15%-40%, silicone powder 1%-3%.
Compared with prior art, the present invention has the advantages that: (1), the present invention have high temperature resistant, good toughness, cost performance
The advantages that high；(2), PA46 and PEEK is polar material, and the two has good compatibility, and the two is compound can not to be had to be added
Third component compatilizer, while the addition of PA46 can be good at improving the toughness of PEEK material；It (3), can using silicone powder
Work in-process plays the effect of lubrication dispersion, reduces the abrasion between material and machine, improves the wearability of composite material；(4),
Preparation process is simple, directlys adopt melt blending technique.
