In face of this crisis, countries in the world exert research and development and utilize such as natural plant fibre, chitosan, first
Shell element a kind of " green material ".Wherein, natural plant fibre is standby with the advantages that its yield is big, biodegradable, function admirable
Attract attention.The advantages of natural plant fibre based composites synthesized by it combine natural plant fibre and synthetic resin,
The application of synthetic resin is instead of in certain limit.However, the poor compatibility between pole filter and non-polar resin, Yi Jizhi
The factors such as the thermal degradation of fibres process cause the decline of composite property, constrain it and promote and apply.Therefore,
It is extremely urgent to find a kind of new type natural plant fiber-based method for synthesizing composite material.
Utility model content
For the deficiency of existing natural fibre based composites, propose a kind of fine based on fluid channel molecular collision in-situ polymerization
Tie up surface modification technology.
The technical solution of the utility model is that the PVC of in-situ polymerization is modified into fiber table using fluid channel molecular collision technology
Face, concrete scheme are as follows：
A kind of fluid channel molecular collision in-situ polymerization fiber surface decorating device, including shell and rotating shaft.Contain on shell
Gas access, liquid inlet, gas vent, runner top and liquid outlet.Runner bottom is fixed with rotating shaft.Gas vent and
Liquid inlet is located at directly over shell, and liquid outlet is located at below shell.It is gentle that runner top with shell is fixed on liquid inlet
At under body outlet just, runner top is alignd with gas vent, and liquid inlet is kept certain height with runner top.Runner bottom with
Runner top is coaxial, keeps certain interval.Zigzag structure is distributed with runner lower surface.Rotating shaft by outer casing underpart stretch out and it is close
Envelope.Gas access is alignd with runner top and runner bottom gap, circumferentially uniform along shell, with ensure gas even into.
By taking polyvinyl chloride covered fiber as an example, VCM enters from gas access by shell, reaches runner top
And the outlet of runner lower external, along its gap ecto-entad flowing.Solidliquid mixture containing fiber, initiator and water is through liquid
Body entrance flows to underface, reaches runner top and runner lower interior portion entrance, is flowed from inside to outside along its gap.Due to
Rotating shaft drives runner bottom to carry out high speed rotary motion, and solidliquid mixture touches runner bottom and outwards got rid of along gap, runner
The broached-tooth design of lower surface is ground into droplet, and the VCM back flow of gas come with ecto-entad collides, and carries out
Polymerisation, simultaneously because the polyvinyl chloride of polarity encounters the fiber of polarity, generation polyvinyl chloride covered fiber is passed through with liquid
Cross runner top and runner lower external entrance goes out, discharged by liquid outlet, the VCM gas of residual goes out through gas
Mouth discharge.Wherein, the structure on runner top and runner bottom can be advantageous to improve molecular collision efficiency by rationally designing.Stream
The broached-tooth design of road bottom is not to hinder fiber flow to control sawtooth degree as principle.Gas access keeps certain with runner exit
Distance, to prevent solidliquid mixture from being thrown away by gas access.Liquid inlet forms certain angle with shell, so that when reserved enough
Between prevent VCM gas from quickly overflowing.
Because solidliquid mixture experienced the process that motion is crushed, adverse current is collided in runner gap so that polymerisation increases
Add specific surface area, substantially prolongs reaction time, greatly enhancing mass and heat transfer process, while equipment volume can be reduced,
Securely and reliably, fiber-base composite materials yield is improved.
A kind of fluid channel molecular collision in-situ polymerization fiber surface decorating device of the utility model, the advantage is that：(1) increase
Add reaction contact specific surface area, extend reaction time, greatly enhancing mass and heat transfer process；(2) polarity caused by utilizing
Polyvinyl chloride carries out molecular collision in-situ polymerization with polarity string, can effectively realize polyvinyl chloride cladding string
Form fiber-base composite materials；(3) consersion unit volume can be reduced, while increase yield, reduce cost.
