Abstract
The processing method that the invention discloses a kind of GFRTP material strip, comprises the following steps: (1) multiply GF yarn, by preimpregnation mould infiltration plastic molten mass, obtains GFRTP material strip；(2) GFRTP material strip is by entering traction machine after boundling die bundling, a diameter of 0.5 1.5mm of GFRTP material strip after traction machine traction stretching；(3) the GFRTP material strip that traction machine pulls out is by the rolling respectively of single winder.The processing method of a kind of GFRTP material strip of the present invention, the material strip diameter obtained is little, it is possible to meet the performance requirement needed for subsequent production, can meet the production requirement of the product of different shape, and processing technique is simple, has good using value.
Description
Technical field
Glass fiber reinforcement thermoplasticity moulding mixture field of the present invention, the processing method of a kind of GFRTP material strip.
Background technology
During FRP is born in World War II, obtain very fast development after World War II.And GRTP relatively FRP is born evening, but it is relatively
FRP possesses many superioritys, both with development speed faster, and FRP waste and waste and old product can not regeneration, FRTP is then
Can repeatedly recycling, for environmental protection friendly material, both replace FRP in many fields with it, but due to some power of FRTP
Learn performance not as FRP, both with countries in the world, this was furtherd investigate, and make a breakthrough, such as Sheng Geban company of France 1988 years
The TWINTEX of research and development, carries out with GF production in thermoplastic fibroblast production process simultaneously, produces GF/ thermoplastic fibre multiple
Close yarn, then can be processed into GFRTP material strip, tremble and draw, produce GFRTP fabric sheet, sheet material class material, it is provided that composite product
Manufacturer is processed further GFRTP parts.Existing production GFRTPDE technical difficulty is high, and fund input is relatively big, and technique falls
After, need to improve.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention provides the processing side of a kind of GFRTP material strip
Method.
Technical scheme: for solving above-mentioned technical problem, the processing method of a kind of GFRTP material strip of the present invention, including following
Step:
(1) multiply GF yarn is by preimpregnation mould infiltration plastic molten mass, obtains GFRTP material strip；
(2) GFRTP material strip is by entering traction machine after boundling die bundling, the GFRTP material strip after traction machine traction stretching
A diameter of 0.5-1.5mm；
(3) the GFRTP material strip that traction machine pulls out is by the rolling respectively of single winder.
Wherein, preimpregnation mould connects hot-melt extruded machine, after the plastic molten mass of hot-melt extruded machine extrusion enters preimpregnation mould
Infiltration GF yarn.
Wherein, the GF content in the GFRTP material strip after infiltration is 50-70%.
Wherein, the yarn count of GF yarn is 60-600tex.
Beneficial effect: the processing method of a kind of GFRTP material strip of the present invention, the material strip diameter obtained is little, it is possible to after Man Zuing
Performance requirement needed for continuous production, can meet the production requirement of the product of different shape, and processing technique is simple, has good answering
By value.
Accompanying drawing explanation
Fig. 1 is the process chart of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is further described.
As it is shown in figure 1, the processing method of a kind of GFRTP material strip, comprise the following steps:
(1) multiply GF yarn is by preimpregnation mould infiltration plastic molten mass, obtains GFRTP material strip；
(2) GFRTP material strip is by entering traction machine after boundling die bundling, the GFRTP material strip after traction machine traction stretching
A diameter of 0.5-1.5mm；
(3) the GFRTP material strip that traction machine pulls out is by the rolling respectively of single winder.
Wherein, preimpregnation mould connects hot-melt extruded machine, after the plastic molten mass of hot-melt extruded machine extrusion enters preimpregnation mould
Infiltration GF yarn.
Wherein, the GF content in the GFRTP material strip after infiltration is 50-70%.
Wherein, the yarn count of GF yarn is 60-600tex.
The processing method of a kind of GFRTP material strip of the present invention, uses quantity-produced mode, controls the material after traction stretching
Bar diameter so that the material strip obtained can adapt to the processing of follow-up other finished products various, it is not necessary to secondary operations, and processes
Technique is simple, has good using value.
The above is only the preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
