Abstract
The invention discloses a kind of corrosion-resistant end plane sealing strip PPS resin composite, it is made up of by mass percentage following components：Carbon fiber：12 22%, PTFE：5 15%, modified montmorillonoid：5 15%, graphene：1 4%, coupling agent：1 2%, lubricant：0.2 0.5%, antioxidant：0.5 1%, surplus PPS；The modified montmorillonoid is that sodium-based montmorillonite forms through ethylene benzyl dimethyl stearyl ammonium chloride.Its preparation method is also disclosed.In the present invention, carbon fiber is added in PPS can increase shock resistance, tensile property, bending property and compression performance, reduction creep.Addition PTFE can reduce coefficient of friction, lift toughness, improve decay resistance.Modified montmorillonoid, graphene can effectively improve the mechanical performance and corrosion resistance of material.Corrosion-resistant end plane sealing strip has good corrosion resistance made from material of the present invention, still has good toughness, service life length in the case where being contacted for a long time with refrigeration oil.
Description
Technical field
It is compound with corrosion-resistant end plane sealing strip PPS resin the present invention relates to the air-conditioning screw compressor on new-energy automobile
Material and preparation method thereof, belong to field of compound material.
Background technology
Polyphenylene sulfide（PPS）Excellent with endurance, UV resistant, weatherability is excellent, can long-term outdoor use, it is fire-retardant
Function admirable, oxygen index (OI) is high, and continuous use temperature reaches as high as 260 DEG C, but due to its own design feature, causes PPS to have
The defects of certain, poor toughness is mainly reflected in, fragility is big, and anti-bending strength is bad, and in Long Term Contact corrosive substance, it is broken
Elongation declines obvious.
It is general on using motor as the new-energy automobile of major impetus to use air-conditioning screw compressor as refrigeration power.
Air-conditioning screw compressor is the compressor that refrigeration is played with compression refrigerant, by a fixed involute scroll plate and one
The individual involute motion scroll plate composition in eccentric convolution translation.End plane sealing strip be constantly exposed in use refrigerant and
In the environment of lubrication refrigeration oil, and refrigeration oil has corrosivity, therefore seal ring material needs stronger corrosion resistance.
The content of the invention
It is an object of the invention to provide a kind of corrosion-resistant end plane sealing strip PPS resin composite, has well resistance to
Corrosive nature.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of corrosion-resistant end plane sealing strip is answered with PPS resin
Condensation material, it is characterised in that：It is made up of by mass percentage following components：
Carbon fiber：12-22%
PTFE：5-15%
Modified montmorillonoid：5-15%
Graphene：1-4%
Coupling agent：1-2%

Surplus is PPS；
The modified montmorillonoid is that sodium-based montmorillonite forms through ethylene benzyl dimethyl stearyl ammonium chloride.
Preferably, the coupling agent is silane coupler.
Preferably, the antioxidant is phosphorous acid esters.
Preferably, the lubricant is dimethicone.
Preferably, the acidified modification of the carbon fiber.
The invention also discloses the preparation method of above-mentioned corrosion-resistant end plane sealing strip, its step includes：
（1）, 10 parts of sodium-based montmorillonites, 2 parts of sodium hydroxides, 5 parts of ethylene benzyl dimethyl stearyl ammonium chlorides are added to the water
After being warming up to 50 DEG C of stirrings, centrifugation obtains sediment, is dried after sediment is washed to neutrality, obtains modified montmorillonoid；
（2）, carbon fiber after acetone soak, wash, drying, add acid solution in heating stirring after filter, wash to neutrality, obtain
The carbon fiber of acidifying；
（3）, weigh raw material according to quantity, 150 DEG C dry 2 ~ 6h, add high speed mixer in, taken out after 2 ~ 3min of high-speed stirred；
（4）, mixed raw material add vertical screw extruder, 300 ~ 400 DEG C of barrel temperature, 330 ~ 380 DEG C of nozzle temperature, mould
120 ~ 180 DEG C of temperature, using medium injection pressure, 2 ~ 10s of pressurize, pressurize, molded after cooling down 5 ~ 40s, runner is removed after the demoulding, is repaiied
Whole cast gate, then product is ground, except deburring and thimble vestige.
Preferably, the acid solution is the concentrated sulfuric acid or concentrated nitric acid.
In the present invention, carbon fiber addition carbon fibre is added in PPS can increase shock resistance, tensile property, bendability
Energy and compression performance, reduce creep.Addition PTFE can reduce coefficient of friction, lift toughness, improve decay resistance.It is modified
Montmorillonite, graphene can effectively improve the mechanical performance and corrosion resistance of material.The new-energy automobile made from material of the present invention
On air-conditioning screw compressor there is good corrosion resistance with corrosion-resistant end plane sealing strip, in the feelings contacted for a long time with refrigeration oil
Still there is good toughness, service life length under condition.
