Description
Technical field
The present invention relates to glass fibre production technical field more particularly to a kind of pre-dispersed plastics special glass fiber productions
Method and twisting equipment.
Background technique
Glass fibre is used for higher modulus, and chemical property is stablized, cheap, thus the compound increasing as many materials
By force.Increase just enhancing using the non-twist glass of alkali-free in the plastic, increasing heat resistance widens the application field of plastic material significantly,
Some occasions even replace steel to use.Traditional plastics are with glass fiber reinforcement method at present: by resin, dispersing agent, steady
Determine the auxiliary agents such as agent to be uniformly mixed, then pass through twin-screw heating and melting, glass pricker dimension silk is added by the fuselage of double screw extruder
In the plastics that material mouth feeding has been melted, glass fibre cutting is dispersed in plastic melt by the shearing original part of twin-screw,
Then head discharge hole is squeezed out, using cooling, pelletizing is drawn, produces the modifying plastics material of glass fiber reinforcement.But its
Glass fibre shearing dispersing technology is fused together with extrusion process, and the process is more complicated, and flexibility is poor, and application range is limited,
And the performance of reinforced plastics is also to be improved.
Summary of the invention
In order to solve the above technical problems, the object of the present invention is to provide the pre-dispersed of a kind of simple process and high production efficiency
Plastics special glass fiber production method and twisting equipment.
Technical scheme is as follows:
A kind of pre-dispersed plastics special glass fiber production method, the method are made of following steps: step 1, more
Stock filament of glass fiber is drawn；Step 2 is opened multiply filament of glass fiber by sprawling device arrangement in mold；Step 3,
The coating agent of thawing is coated uniformly on the surface of every filament of glass fiber；Step 4, to the filament of glass fiber in mold
It is twisted, removes extra coating agent；Step 5, it is cooling；Step 6, traction；Step 7, cutting；It can be by glass fibre
Pre-dispersed processing is carried out, produces the novel pre-dispersed glass fiber material that content of glass fiber reaches 80% or more, effectively
The performance for improving production efficiency and reinforced plastics, simplifies production technology.
Preferably, the filament of glass fiber is alkali-free glass fibre of the diameter at 13~17 μm, so that glass fibre is long
Integral strength and rigidity are preferable after silk is cut off, and effectively further improve the performance of reinforced plastics.
Preferably, the coating agent is polyethylene wax grafted maleic anhydride, and coating agent is had with a variety of plastics
Intermiscibility effectively improves the bond strength of glass fibre and plastics.
Preferably, a kind of to twist equipment used in the pre-dispersed plastics special glass fiber production method, by two plus
Component is twisted to filling；The twist unit includes pressure roller 1, traction device 2, idler wheel 3, support 4, crawler belt 5 and fixing seat 6；Institute
The setting of support 4 is stated at 2 side both ends of traction device, the idler wheel 3 is rolled with support 4 to be connected, and the crawler belt 5 is connected to both ends
On idler wheel 3, the pressure roller 1 is disposed side by side on 5 inside of crawler belt, and is connect by fixing seat 6 with support 4, so that glass fibre is long
Silk 7 can be clamped by crawler belt, and be pulled under drive to filament of glass fiber 7 in traction device, at the same it is upper and lower two it is suitable
The crawler belt of hour hands rotation can twist filament of glass fiber, remove extra coating agent, effectively improve twisting
Efficiency and quality.
Detailed description of the invention
Fig. 1 is front view of the invention；
Fig. 2 is right view of the invention；
In figure: pressure roller 1, traction device 2, idler wheel 3, support 4, crawler belt 5, fixing seat 6, filament of glass fiber 7.
Specific embodiment
