Description
Technical field
The invention belongs to modification regeneration polyvinyl chloride technical field more particularly to a kind of wood powder modification regeneration polyvinyl chloride groups
Close object and preparation method thereof.
Background technique
Wood powder modification regeneration polychloroethylene composition, can not only make full use of regeneration polyvinyl chloride, can be with its reduction
Cost.Modified plastic industry application wood powder is a kind of behave turned waste into wealth, and can give increasing peasant income.
However, there are the following problems for meeting by hot-forming: 1, wood powder and regeneration polyvinyl chloride poor compatibility, it is final to produce
Product poor mechanical property；2, polyvinyl chloride and wood powder are regenerated since bulk density differs greatly, and are difficult to be uniformly mixed；In addition wood powder exists
When mixing, shearing force is stronger when due to batch mixer mixing, and wood powder is easily burnt；3, wood powder and regeneration polyvinyl chloride are all polarity
, wood powder surface has the acid that can make to regenerate polyvinyl chloride degradation, and the hydrochloric acid for making wood powder degrade can be generated by regenerating polyvinyl chloride.
Summary of the invention
The object of the invention is to provide a kind of wood powder modification regeneration polychlorostyrene second to overcome above-mentioned prior art defect
The preparation method of ene compositions.
Technical scheme is as follows:
A kind of wood powder modification regeneration polychloroethylene composition is prepared by weight by following components:
Further scheme, the chlorinated paraffin are the chlorinated paraffin 70 that viscosity average molecular weigh is 1000.
The partial size of the wood powder is 120-150 mesh, and wood powder moisture content is less than 2wt%.
The moisture content of the regeneration polyvinyl chloride is less than 4wt%.
The antioxidant is selected from three (2.2- di-tert-butyl-phenyl) phosphite esters, four (β-(3,5- di-t-butyl -2- hydroxyls
Phenyl) propionic acid) at least one of pentaerythritol ester and the double octadecyls of thio-2 acid.
Another goal of the invention of the invention is to provide a kind of preparation of above-mentioned wood powder modification regeneration polychloroethylene composition
Method, its step are as follows:
(1) 100 parts and chlorinated paraffin 1-2 parts of polyvinyl chloride will be regenerated, is added in batch mixer and/min mixing is turned with 600-800
2-5 minutes；
(2) it is added after wood powder 25-55 parts and is continuesd to mix 2-5 minutes with 300-400 turns/min；
(3) 2-3 parts and antioxidant 0.3-0.8 parts of haloflex are eventually adding, obtains mixture after continueing to mix 1-2min；
(4) mixture is placed in heat pressing and molding mold first precompressed, it is then hot-forming, obtain polychloroethylene composition.
Further scheme, pressure 2-3mpa, the time 10-30s of the precompressed；The hot-forming temperature 160-200
DEG C, pressure 20-100mpa, time 5-30 minute.
The present invention select viscosity average molecular weigh be 1000 chlorinated paraffin 70 used as lubricant and binder, make its with again
Raw polyvinyl chloride is mixed, and the effect of the greasy property and adherency wood powder in material processing can not only be improved, moreover it is possible to
Inhibit regeneration polyvinyl chloride to generate hydrochloric acid in process and the acid corrosion on wood powder surface is inhibited to regenerate polyvinyl chloride.This is other
The characteristic that lubricant does not have.
In addition, the viscosity average molecular weigh of chlorinated paraffin 70 cannot be too big or too small, otherwise as binder in use, can go out
It is now not easy to adhere to wood powder or causes to adhere to non-uniform problem；As lubricant in use, will appear lubricant effect difference ask
Topic.
The present invention selects partial size to carry out modification regeneration polyvinyl chloride for the wood powder of 120-150 mesh, reaches composition properties most
Excellent, partial size is too big or too small, all composition properties can be caused poor because of easy to reunite or other reasons.
The present invention selects the regeneration polyvinyl chloride of moisture content < 4% as raw material, if its moisture content is high, in extrusion process
In be easy to cause degradation of polypropylene, polypropene composition to be easy to appear broken strip phenomenon during tie rod；
The present invention is added haloflex and plays the role of increasing regeneration polyvinyl chloride and wood powder compatibility.
The present invention uses batch mixed, first mixes regeneration polyvinyl chloride and chlorinated paraffin, and selects suitable mixed
Close time and mixing velocity, it is therefore an objective to so that chlorinated paraffin is sheared power friction overheat in mixing and is melted, it is then uniform attached
Regeneration polyvinyl chloride surface.Then it adds wood powder to continues to mix 2-5 minutes with 300-400 turns/min, after making fusing
Wood powder can be adhered to regeneration particulate polyvinyl chloride surface by chlorinated paraffin.Because connection regeneration polyvinyl chloride and wood powder is " viscous
Tie agent " it is exactly chlorinated paraffin, so mixing velocity at this time cannot be too fast, it not so will lead to part wood powder " being burnt ".Finally
Haloflex is added and antioxidant continuess to mix to obtain mixture, this uniformly mixed material can store in a long time,
It is used as binder if it is chlorinated paraffin is substituted with liquid-containing binder, then must uses, cannot be stored up immediately in a short time
It deposits.
Present invention selection is hot-forming, the purpose is to increase the plasticity of composition, evaporates the moisture in slab.
