The generation of ester material brings very big burden to environment and leads to some relevant social concerns.Therefore, makrolon material
Recovery technology receives the extensive concern of people.
CN104877168A provides a kind of recovery method of makrolon.The solvent that this method selects solubility property good is made
For reaction medium, makrolon and solvent are added in there-necked flask, after makrolon is completely dissolved, by catalyst, alcoholysis agent
It is added in reaction system, carries out alcoholysis reaction, wait for after reaction, reaction solution is washed, suction filtration is dried process, obtains
To alcoholysis product of the end with hydroxyl and different viscosity numbers identical from makrolon repeating segment structure.After reaction, instead
The last handling processes such as system is washed, filters, is dry are answered to obtain alcoholysis product.The recovery method is under mild conditions to poly- carbon
Acid esters is degraded;The product of different chain links is obtained by the reaction condition for setting different;Because its product both ends carries hydroxyl energy
Polycondensation reaction is carried out with other proper monomers, to recycling for the makrolon of realization truly.
CN106432797A discloses a kind of recovery process of waste and old cross-linked polycarbonate, and steps are as follows:Step 1) is waste and old
The pretreatment of cross-linked polycarbonate:Waste and old cross-linked polycarbonate is subjected to surface spraying cleaning and ultraviolet sterilization;Step 2) is useless
The depolymerization of old cross-linked polycarbonate is recycled:After crushed by step 1) treated waste and old cross-linked polycarbonate, extruder is added,
Under high temperature and alternating shear effect so that depolymerization occurs for the strand of cross-linked polycarbonate, realizes and recycles.The invention
Advantageous effect is:It can with environment-friendly high-efficiency depolymerization cross-linked polycarbonate so that the makrolon after depolymerization has temperature flowing
And machinability, the production of articles in downstream is directly applied to, pollution and the low efficiency problem of traditional treatment method are solved.
CN101665584A provides a kind of recovery method of makrolon, includes the following steps:Recycle the plastic cement of PC compositions
Part->Cleaning->Cleaning->Cooling broken->Clean again->Dewatered drying->Add additive extrusion molding;Wherein add
Doping extrusion molding specifically includes, and is equipped with again using extruder as capital equipment and adds additivated auxiliary device in temperature
MBS series toughener, the 1%- of ABS, 3-10% of 10-85% are added at a temperature of 240 DEG C -300 DEG C by weight percentage
The lubricant of 10%SMA phase solvents and 0.1-0.5%, surplus are that PC plastic cement is stirred simultaneously extrusion molding.Added using above-mentioned
Add formula that can produce not flame retardant series PC/ABS alloy materials of substitution import performance completely, is widely used in mobile phone electricity
Brain shell electron-like electricity.
Currently, scholars study PC chemistry deagglomeration problems when, mainly by thermal cracking, hydrolysis, alcoholysis and surpass
(It is sub-)The methods of depolymerization under critical depolymerization and ionic liquid environment realization, but during depolymerization, it cannot be to catalyst
It is recycled, this results in will produce a large amount of waste residue in depolymehzation process, and is brought seriously to the equipment that depolymerization uses
Corrosive effect.
