Description
Technical field
The present invention relates to a kind of thermoplastic composite, in particular to a kind of increasing of carbon fiber PA66 thermoplastic composite
Strong PA66.
Background technique
Carbon fiber PA66 thermoplastic composite is an important branch in composite material, since it has excellent performance, closely
The purposes and yield of this material gradually expand over year.The main component of carbon fiber PA66 thermoplastic composite is PA66 base
Material, carbon fiber and auxiliary agent.The features such as material is good, thermal expansion coefficient is small, good corrosion resistance with fatigue strength is widely used in boat
It, sport, automobile, medical treatment, the industries such as IT.
, using PA66 as matrix, PA66 heat resistance is preferable for it, and wearability is good.But the heat distortion temperature of pure nylon it is lower,
Size is unstable, and impact resistance is poor.It therefore can tensile strength to carbon fiber PA66 thermoplastic composite, shock resistance
The mechanical properties such as intensity and bending strength will receive certain influence.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of carbon fiber PA66 of mechanical strength for improving material
The reinforced plastic PA66 of thermoplastic composite.
To achieve the above object, the present invention provides the following technical scheme that a kind of carbon fiber PA66 thermoplastic composite
Reinforced plastic PA66, it is characterised in that: include PA66 resin 85% -95%, polyphenylene oxide 0.1% -0.5%, alkali-free glass fibre
0.1% -2%, silicon carbide fibre 1% -3%, γ-(methacryloxy) propyl trimethoxy silicane modified manometer silicon dioxide
1% -8%, auxiliary agent 2% -5%.
Wherein, auxiliary agent includes antioxidant, toughener and coupling agent, and proportion is 1:1:2.
Antioxidant is Hinered phenols antioxidant, phosphite ester antioxidant.
Toughener is thermoplastic elastomer (TPE) class toughener.
Coupling agent is one or both of KH550, KH560, KH570 or KH792.
By adopting the above technical scheme, enhance the power of nylon by organically-modified nano silica, silicon carbide fibre
Performance is learned, modified nano silica is good with nylon compatibility, and silicon carbide is uniformly distributed therein, and effectively increases Buddhist nun
The mechanical properties such as tensile strength, impact strength and the bending strength of dragon.The addition of polyphenylene oxide so that synthetic material it is antistatic
Performance is obviously improved；Doping plasticizing agent improves toughness and comprehensive performance in synthetic material.
Specific embodiment
The present invention is a kind of reinforced plastic PA66 of carbon fiber PA66 thermoplastic composite, includes PA66 resin 85%-

Base) propyl trimethoxy silicane modified manometer silicon dioxide 1% -8%, auxiliary agent 2% -5%.In above scheme, process is organically-modified
Nano silica, silicon carbide fibre enhance the mechanical property of nylon, modified nano silica is compatible with nylon
Property is good, and silicon carbide is uniformly distributed therein, and effectively increases the power such as the tensile strength, impact strength and bending strength of nylon
Learn performance.The addition of polyphenylene oxide is so that the antistatic property of synthetic material is obviously improved；Doping plasticizing agent improves in synthetic material
Toughness and comprehensive performance.
In embodiments of the present invention, auxiliary agent includes antioxidant, toughener and coupling agent, and proportion is 1:1:2.Antioxidant
For Hinered phenols antioxidant, phosphite ester antioxidant.Toughener is thermoplastic elastomer (TPE) class toughener.Coupling agent is
One or both of KH550, KH560, KH570 or KH792.
In the embodiment of the present invention 1, PA66 resin 85%, polyphenylene oxide 0.1%, alkali-free glass fibre 0.1%, silicon carbide fibre
1%, γ-(methacryloxy) propyl trimethoxy silicane modified manometer silicon dioxide 1%, auxiliary agent 2%.
In the embodiment of the present invention 2, PA66 resin 90%, polyphenylene oxide 0.3%, alkali-free glass fibre 1%, silicon carbide fibre 2%,
γ-(methacryloxy) propyl trimethoxy silicane modified manometer silicon dioxide 4%, auxiliary agent 3%.
In the embodiment of the present invention 3, PA66 resin 95%, polyphenylene oxide 0.5%, alkali-free glass fibre 2%, silicon carbide fibre 3%,
γ-(methacryloxy) propyl trimethoxy silicane modified manometer silicon dioxide 8%, auxiliary agent 5%.
| Performance | Embodiment 1 | Embodiment 2 | Embodiment 3 |
| Bending strength MPa | 135 | 142 | 148 |
| Tensile strength MPa | 122 | 125 | 131 |
As seen from the above table, embodiment 1-3 resulting materials have good mechanical property, and bending strength is up to 148
MPa, tensile strength is up to 131MPa.
