Abstract
The invention provides recycled polycarbonate reinforced and toughened through an isomeric crosslinking method and a preparation method of the recycled polycarbonate and relates to a plastic material and a preparation method thereof. Firstly, recycled polycarbonate is subjected to forced air drying for 6-8 hours at the temperature of 80 DEG C; the dried recycled polycarbonate, a crosslinking master batch and inorganic filler are weighed according to the weight proportion and put in a high mixer to be mixed for 4-6 min, extrusion palletizing is conducted through a double-screw extruder at the temperature of 220 DEG C to 280 DEG C, and then the product is obtained. According to a traditional recycling method, an elastomer toughening agent is added for toughening, usually the tensile property of polycarbonate recycled materials is reduced, and therefore the whole mechanical performance is affected. According to the technical scheme, the effects of reinforcing and toughening the recycling polycarbonate can be achieved at the same time, the toughness and strength of regenerated polycarbonate can be good without adding compatilizer in the regeneration process of the recycled polycarbonate, and high market promotional value is achieved.
Description
Technical field
The present invention relates to a kind of plastic material and preparation method thereof, more particularly to a kind of isomerism cross-linking method strengthens
Toughness reinforcing reclaims makrolon and preparation method thereof.
Background technology
Makrolon (abbreviation PC) is the high molecular polymer containing carbonate group in strand, and the structure according to ester group can
It is divided into the polytypes such as aliphatic, aromatic series, aliphatic-aromatic.Wherein due to aliphatic and the poly- carbonic acid of aliphatic-aromatic
The mechanical performance of ester is relatively low, so as to limit its application in terms of engineering plastics.Only aromatic copolycarbonate is obtained at present
Industrialized production.It is most fast as growth rate in five large-engineering plastics due to the particularity on polycarbonate structure
General engineering plastic.
PC is the amorphous polymer of almost colourless glassy state, there is optical well.PC high molecular weight resins have very
Toughness high, Izod notched impact strength is 600-900J/m, and the heat distortion temperature for being not filled by the trade mark is about 130 °C, glass
This numerical value can be made after glass fiber reinforcement increases by 10 °C.The bending modulus of PC can be processed into greatly up to more than 2400MPa, resin
Rigid articles.During less than 100 °C, creep rate under a load is very low.PC hydrolytic resistances are poor, it is impossible to for repeating to undergo height
Press the product of steam.PC main performance defects are not high enough stability to hydrolysis resistance, and to notch sensitive, resistance to organic chemistry moral character is resistance to
Scratch is poor, can be turned to be yellow in ultraviolet for a long time.As other resins, PC is easily soaked by some organic solvents
It is turbid.
In recent years, with the demand of industrial development, concern of the people to the study on the modification of makrolon also all the more.Modified PC
Purpose be for toughness reinforcing, to improve moulding processability, reduce residual deformation, increase anti-flammability etc., the product of the specific PC that can be modified
Planting has：PC/ABS can improve bending modulus, heat resistance, plating performance etc..PC/PET, PBT can improve resistance to chemical reagents, solvent resistant material
Property etc..PC/PMMA addition lucite can improve outward appearance pearly-lustre color.PC/PA, HIPS can improve impact flexibility, any surface finish
Degree.PC/HDPE can improve boiling water resistance, resistance to ag(e)ing, against weather, and LDPE effects are poor.PC glasses or carbon fiber enter
Row enhancing is modified, improve mechanical strength.And with brominated flame retardant and antimony oxide, can be made into flame retardant grade PC.
