Abstract
A thermosetting plastic recycling technology comprises the following steps: (1) sorting separation; (2) cleaning and drying; (3) crushing; (4) degradation regeneration; (5) mixing; and (6) compression molding. Mechanical force and heat make the molecular structure and the chemical structure of thermosetting plastics change and convert mechanical energy into heat energy in order to promote fracture of the molecular structure with weak bond energy and generate new active functional groups, so generated materials have certain plasticity, and the thermosetting plastics are plastic molded to realize cycle reuse.
Description
Technical field
The present invention relates to a kind of plastics recycling process, particularly relate to the reclaiming technique of a kind of thermosetting plastics.
Background technology
Current global resource consumption is huge, if technics of reclaim of plastic waste recycled, just can alleviate non-renewable money
The consumption in source, it is achieved sustainable development, but the recovering effect of waste or used plastics is but and unsatisfactory, late 1980s,
U.S.'s technics of reclaim of plastic waste rate is 35%, and China only below 20% the recovery of waste or used plastics with exploitation Resources compared with,
Cost is relatively low, so the recovery of waste or used plastics has the most wide market and potentiality, technics of reclaim of plastic waste is recycled, permissible
Effectively solving the wasting of resources and environmental pollution, the recycling to waste and old thermoplastic is studied more ripe, and thermosetting
Plastics due to premium properties such as its hardness are high, intensity is big, high temperature resistant, want to reclaim that to produce the recycled product of high value be difficulty
, therefore, the most effectively by waste and old thermosetting plastics recycling, and improve its response rate, be current plastic industry
It is badly in need of the major issue solved.
Summary of the invention
The present invention solves that the problems referred to above provide a kind of thermosetting plastics reclaiming technique.
The technical solution used in the present invention:
A kind of thermosetting plastics reclaiming technique, its step is as follows:
(1) sorting separates: the thermosetting plastics complicated to source sorts, and removes metal waste, it is to avoid follow-up work
Damage equipment in work；
(2) clean and be dried: to the waste or used plastics cleansing article polluted by greasy dirt, silt, rubbish etc. to some extent；
(3) pulverize: the waste and old thermosetting plastic cleaned up is put in crushing device, it is carried out coarse pulverization；Then
Carry out separating twice, i.e. carry out finely divided and screening operation, it is thus achieved that particle size diameter is more than the powder of 20 mesh；
(4) degraded regeneration: the powder of separating twice is admitted to degraded and regenerating unit, degraded regenerating unit high speed rotates
Cutter separating twice material is applied various mechanical force, separating twice material through shearing, extrude, impact, friction mechanism power
The frictional heat comprehensive function produced during and, regenerates through degraded after a while so that the particle diameter of separating twice material becomes
Less, miniaturization, it is thus achieved that particle size diameter is more than the renewable powder of degraded of 200 mesh；
(5) mixing: renewable for degraded powder is transported in mixing arrangement, and add a small amount of in mixing arrangement simultaneously
Thermoplastic and auxiliary agent, the cutter rotated in mixing arrangement is by renewable for degraded powder and adds pan feeding mixing, is made by mixing
With promoting thermoplastic and the intermolecular generation chemical reaction of thermosetting plastics, make thermosetting plastics have plasticity, obtain
There is the compound of more high activity and plasticity；
(6) compression molding: be transported in compression molding device be pressed into by active and plastic compound to have
The composite product of certain mechanical property.
The thermoplastic added in described step (5) is thermoplastic polyvinyl chloride, and auxiliary agent is antioxidant and lubrication
Agent.
Beneficial effects of the present invention: thermosetting plastics is under the comprehensive function of mechanical force and heat, and molecular structure and chemistry are tied
Structure changes, and changes mechanical energy is heat energy simultaneously, and the molecular structure promoting bond energy more weak ruptures, and generates new active official
Can group, make regeneration feed have certain plasticity, it is achieved thermosetting plastics Plastic Forming again and cycling and reutilization.
Detailed description of the invention
A kind of thermosetting plastics reclaiming technique, its step is as follows:
(1) sorting separates: the thermosetting plastics complicated to source sorts, and removes metal waste, it is to avoid follow-up work
Damage equipment in work；
(2) clean and be dried: to the waste or used plastics cleansing article polluted by greasy dirt, silt, rubbish etc. to some extent；
(3) pulverize: the waste and old thermosetting plastic cleaned up is put in crushing device, it is carried out coarse pulverization；Then
Carry out separating twice, i.e. carry out finely divided and screening operation, it is thus achieved that particle size diameter is more than the powder of 20 mesh；
(4) degraded regeneration: the powder of separating twice is admitted to degraded and regenerating unit, degraded regenerating unit high speed rotates
Cutter separating twice material is applied various mechanical force, separating twice material through shearing, extrude, impact, friction mechanism power
The frictional heat comprehensive function produced during and, regenerates through degraded after a while so that the particle diameter of separating twice material becomes
Less, miniaturization, it is thus achieved that particle size diameter is more than the renewable powder of degraded of 200 mesh；
(5) mixing: renewable for degraded powder is transported in mixing arrangement, and add a small amount of in mixing arrangement simultaneously
Thermoplastic polyvinyl chloride and auxiliary agent antioxidant and lubricant, the cutter rotated in mixing arrangement by renewable for degraded powder with add
Pan feeding mixes, and promotes thermoplastic and the intermolecular generation chemical reaction of thermosetting plastics by immixture, makes thermosetting
Plastics have plasticity, obtain the compound with more high activity and plasticity；
(6) compression molding: be transported in compression molding device be pressed into by active and plastic compound to have
The composite product of certain mechanical property.
Above one embodiment of the present of invention is described in detail, but described content has been only the preferable enforcement of the present invention
Example, it is impossible to be considered the practical range for limiting the present invention.All impartial changes made according to the present patent application scope and improvement
Deng, within all should still belonging to the patent covering scope of the present invention.
