Background technology
Non-ferrous metal belongs to non-renewable resources, as the increasingly extensive application of special material, non-ferrous metal are more next
More turn into scarce resource, and intermetallic composite coating needs high energy consumption, and processing cost is very high, and quality control stability is poor.Therefore, develop
The material of new alternative non-ferrous metal turns into the research and development focus of material science already.
Nylon (i.e. polyamide) density of material is small, processing characteristics is good, wearability and self lubricity are good, thermal insulation and thermostabilization
Property good, good corrosion resistance, resilience it is high, there is excellent electrical property and higher rigidity, and finished product is without preservative treatment,
Used as a kind of engineering material for substituting non-ferrous metal in every field.Although with a series of excellent performances,
Compared with metal material, also there is intensity, rigidity is relatively low the deficiencies of, make using being subject to certain restrictions.Therefore, people develop
With the kind of the enhancings such as glass fibre, asbestos fibre, carbon fiber, titanium fiber, nylon largely compensate for
Deficiency on energy, wherein using glass fibre reinforced nylon to be most important.
CN103788629A discloses a kind of glass fibre reinforced nylon material, including glass fibre 10-40%, nylon
40-77%, and the auxiliary agent such as lubricant, antioxidant, coupling agent.
CN103788627A discloses a kind of long glass fibre reinforced nylon material, including glass fibre 20-40 parts, nylon
45-80 parts, and the auxiliary agent such as antioxidant, lubricant, compatilizer.
CN103709745A discloses a kind of glass fibre reinforced nylon material, including glass fibre 20-50%, nylon
50-80%, and the auxiliary agent such as rheological agent, compatilizer, calcium stearate.
CN103709743A discloses a kind of glass fibre reinforced nylon material, including nylon 50-60%, glass fibre
25-30%, fire retardant 14-18, and the auxiliary agent such as coupling agent, antioxidant, lubricant.
CN103665857A discloses a kind of glass fibre reinforced nylon material, including nylon 15-50%, nylon 14-

CN103602061A discloses a kind of glass fibre reinforced nylon material, including nylon 33-68 parts, glass fibre
15-30 parts, and the auxiliary agent such as fire retardant, toughener, antioxidant part and lubricant.
At present, glass fibre dosage can be in the relative broad range addition within 50wt%；Usual content is in 15-45wt%
Between, often it is 30wt%, and in the technology of existing production glass fibre reinforced nylon material, the glass fibre dosage upper limit is general
For 60wt%, only a small number of foreign enterprises such as Switzerland EMS can accomplish that glass fibre can not then be extruded more than 60% dosage.
Even, most of producer even 50wt% glass fibre reinforced nylons formula, equipment and production technology still not into
Ripe, material changes colour in the material of extrusion, and serious, material surface is coarse (it is serious to reveal fine degree), and being additionally, since glass fibre can not
It is dispersed, high performance material can not be obtained.

Embodiment
Embodiment 1
Step 1, nylon 6 is mixed with Silane coupling agent KH550.
Step 2, lubrication dispersing agent and heat-resisting stabilizing agent are then added, double screw extruder is sent into after mixing, is kneaded.Step
3, after the completion of mixing, glass fibre is added in extruder by the lateral feeding of extruder；Extrusion.
Wherein, extruder operation temperature is by charging aperture to extrusion cavities, each regional temperature is respectively 230 DEG C, 245 DEG C, 245
℃、240℃、235℃、230℃、225℃、230℃、240℃.Rotating speed is 220-260 revs/min.
In the extruder, the transportation section of screw rod, as depicted in figs. 1 and 2, the existing extruder for being used to produce nylon
In, the helicla flute of screw rod is trapezoid spiral groove (Figure 1A and Fig. 2A), screw channel and screw thread be to this structure, it has been found that
Under the conditions of high content of glass fiber, trapezoid spiral groove easilys lead to carrying capacity deficiency, can not uniformly continuous extrusion, and glass
Often there is broken string phenomenon in glass fiber, can not produce.
In the present embodiment, helicla flute of the screw rod in transportation section is arranged to zigzag helicla flute (such as Figure 1B and Fig. 2 B-2C institutes
Show), wherein, angle is 3 ° between near-end cell wall and plumb line, and angle is 35 ° between opposite wall and plumb line.In the case,
Due to the presence of 35 ° of inclined planes, the carrying capacity enhancing of melt and glass fibre, it is orderly along direction of advance to be advantageous to glass fibre
Arrangement.
In addition, as shown in figure 3, present aspect is improved the extrusion cavities of prior art, in the prior art, extrusion cavities are near
Hold as shallower four sides splayed structure, rather than conical structure, in the case of high content of glass fiber, outlet can be caused to be stranded
Difficulty, or even block.As shown in Figure 3A.Present aspect deepens near-end, as shown in Figure 3 B, the bullet in four directions at melt inlet
It is round and smooth excessive between 10 and cone 11 and cylindrical hole 12 below, in addition, the realization of foregoing zigzag spiral grooves is strong defeated
Power (strong defeated) is sent, glass fibre causes melt and glass fibre described along direction of advance ordered arrangement, the design of bellmouth
It is strong it is defeated during it is more close cohesive, be not in hollow and short-term, be also not in shaggy phenomenon.
Embodiment 2-3
According to the methods described of embodiment 1, the glass fibre reinforced nylon that content of glass fiber is 50wt% and 60wt% is prepared
Dragon 6.
Table 1 gives the physical property of the glass fibre reinforced nylon material under the conditions of several content of glass fiber.
Table 1, the physical property of embodiment 1-3 glass fibre reinforced nylon materials
As can be seen that in the case of 70wt% content of glass fiber, bending strength and bending modulus are maximum, and more than having
Non-ferrous metal and black non-ferrous metal.
Embodiment 4
Screw rod angle between the zigzag helicla flute near-end cell wall and plumb line of transportation section is 3 °, opposite wall and plumb line
Between angle be 30 °.
Embodiment 5
Screw rod angle between the zigzag helicla flute near-end cell wall and plumb line of transportation section is 2 °, opposite wall and plumb line
Between angle be 33 °.
The specific embodiment of the present invention is described in detail above, but it is intended only as example, it is of the invention and unlimited
