Advantage for present invention is: resistance to low temperature is preferable, and has superhigh tenacity.The present invention's
The introducing by glass microballoon of the low temperature resistant super-toughened nylon material, improve its tensile property, bending property and
Add its hardness.Along with the increase of auxiliary agent, the notch shock of nylon material and elongation at break obtain same
Step increases, and melts finger and is reduced；POE can make to melt finger equally to be reduced.But, auxiliary agent and POE all make
The notch shock of nylon material strengthens, and the toughening effect of auxiliary agent is more than POE.So, adjust through rationally
After joining, the resistance to low temperature making gained nylon material is preferable, and has superhigh tenacity.
Detailed description of the invention

Enter remaining component at mixed at high speed agent machine mix homogeneously, by the material of mix homogeneously at double screw extruder
Middle extruding pelletization.
Extruder setup parameter is shown in Table 1:
Table 1:
From the difference of embodiment 1, embodiment 2 to embodiment 8 is that raw material components is different.Specifically it is shown in Table 2.
Table 2:
Meanwhile,

Table 3:
As can be seen from Table 3: during PA66/ auxiliary agent/POE/ glass microballoon=92/2/2/3, stretch, bend and
All there is maximum in hardness, and key factor is in the effect of glass microballoon.Notch shock and elongation at break with
The increase of auxiliary agent ratio and increase, be between 10 parts and 15 parts at auxiliary agent, notch shock significantly improves,
Material has higher toughness.Melt and refer to when auxiliary agent is 5 parts, reach maximum, along with auxiliary agent ratio
Increase, melt finger and reduce, and glass microballoon also reduces and melts finger.Contrast 94/5/0/0 and 86/5/8/0 at melt finger,
Now the content of auxiliary agent is consistent, is distinguished as the content of POE, melting at finger ratio 94/5/0/0 at 86/5/8/0
Melt finger low, reduce so POE can make to melt finger.Auxiliary agent and POE can make the notch shock of nylon66 fiber
Strengthen, and the toughening effect of auxiliary agent is more than POE.Additionally, optimum performance is than for PA66/ auxiliary agent/POE/ glass
Glass microballon=92/2/2/3 and PA66/ auxiliary agent/POE/ glass microballoon=94/5/0/0.Mainly from～the breach punching of 23 DEG C
Hit intensity analysis draws low temperature resistant ultra-toughness, and formula mainly determines, additionally from toughener and auxiliary agent
Combination property need to be considered.That is, from combination property, the low temperature resistant super-toughened nylon material of the present invention has
Preferably resistance to low temperature and preferable toughness.
