Description
Technical field
The present invention relates to the technical field of modifying plastics processing technology, refers in particular to a kind of nano modification PET
The processing technology of bottle reworked material production strap.
Background technology
Originally PET bottle reworked material can be only used for producing terylene short fiber, be used for cotton-wool, bed instead of cotton
Articles for use, toy filling, yarn weaving.Because PET bottle reworked material impurity is more, the article technology of production
Index is poor, causes added value too low.Therefore the price of PET bottle reworked material can not improve all the time, suppress
Useless PET bottle recovery unit price, cause give up bottle prices of PET to cover the cost of recovery, be merely able to according to
Environmental protection by government is subsidized.Therefore, only by research of technique, the added value of PET bottle reworked material is improved,
Applied to the industry of more high level, PET can be finally improved by the strength in market and is given up the recovery of bottle
Rate.
The content of the invention
The present invention is to make up the deficiencies in the prior art, there is provided a kind of nano modification PET bottle reworked material production is beaten
The processing technology of band.Concrete technical scheme step of the present invention is as follows：
Step 1: activation modification nanoscale SiO2：By 1.5% coupling agent of nanosized SiO_2 quality with
2% hyper dispersant is dissolved in ethyl acetate solution and obtains mixed liquor.Nano-SiO2 powder is put into height
During fast kneading machine stirring, mixed liquor is equably sprayed.After stirring 20 minutes, by receiving for activation
Rice SiO2 mixed powders, which take out, is put into the drying 40 minutes of 80 DEG C of baking oven, finally gives active nano SiO2；
Step 2: dry PET bottle reworked material using vacuum drum.After each rotary drum feeding 2000kg,
160 DEG C are kept within first 5 hours to complete pre-crystallized and remove surface water.Drying temperature is raised to 200 DEG C afterwards,
Vacuum keeps below 100pa, co-dried more than 24 hours, until moisture is controlled in below 50ppm.
By small oven by active nano SiO2 water tariff collections within 200ppm.Breaking vacuum rotary drum
Vacuum, the active nano SiO2 of each rotary drum addition PET bottle reworked material quality 1%.Rush in the height of water removal
Purity nitrogen gas, and positive pressure of nitrogen is kept, anti-oxidation, avoid degrading.Drum rotating is reopened, is turned
Raw material free to tumble, mixing 1 hour in drum.The storage tank wait that blowing is transported to strap streamline makes
With；
Step 3：After being sufficiently mixed, the extruder that mixture is transported to PET strap streamlines stores up
Batch can.By screw extruder melting extrusion, the temperature of extruder is than the PET bottle reworked material of routine
Temperature is low 5-10 DEG C.It is set as follows：
One area's temperature：240~255 DEG C, two area's temperature：252~256 DEG C,
Three area's temperature：250~258 DEG C, four area's temperature：256~260 DEG C,
Five area's temperature, 250~262 DEG C, six area's temperature：260~264 DEG C,
Filter temperature：262℃.
Engine speed during extrusion：40~50 revs/min.；
Step 4：Melt filters by candle shape pleated filter.Common screen pack precision can be 500
Mesh or so, but the mesh number that nanosized SiO_2 is modified melt filtration net is less than 400 mesh, otherwise nanoparticle
Son can condense before screen pack blocks filter.Filter temperature is needed than conventional low 5 DEG C, to lower
The degraded of melt；
Step 5：Die head shaping, cold rinse bank are cooled and shaped strap.Pass through drawing-off twice, twice high temperature
Relaxation heat setting, winding shaping.During drawing-off twice, due to the effect of nanosized SiO_2, change
Property PET glass transition temperature it is higher 10 DEG C than conventional, therefore the temperature of drawing-off is than routinely high more than 6 DEG C.
Nanometer SiO 2 particle is distributed in strap inner homogeneous, and modified PET polymer strap is provided with more
High intensity, strap total stretch ratio more than 15% can be improved in multiple drawing-off.PET straps
Total draft multiple is higher, and the PET strap fracture strengths produced are bigger, and elongation is fewer.Production
Nanosized SiO_2 out is modified strap fracture strength and accordingly improves more than 10%, and fracture strength reaches
More than 450MPA, for elongation more than 15%, overall objective reaches the primary section system of external hyperviscosity
The requirement of standby high-strength flatness PET straps.
Step 6：The winding of PET straps is coiled after cold and hot sizing.
The advantage of the invention is that：Invention provides a kind of raising PET bottle reworked material added value
New method, height is produced by adding the direct Screw Extrusion of nanoscale SiO2 blending and modifying PET bottle reworked materials
The technique of intensity PET straps.The technology path of relatively various nanosized SiO_2 modified PETs, it is not necessary to
Multistage is granulated extrusion, it is not necessary to adds numerous fixed assets, is that modified PET bottle reworked material is excellent compared with there is cost
The new technology of gesture.The modified high-strength degree PET that invention is produced by the use of PET bottle reworked material as raw material
Strap quality, reach developed country and use high intensity strap of the hyperviscosity section as raw material production
Quality index.
