Description
Technical field
The invention belongs to field of polymer material preparing technology, and in particular to a kind of poly- second of modification of household electrical appliance production
The manufacture craft of alkene.
Background technology
Polyethylene has good mechanical property, is a kind of common plastics, is widely used in household electrical appliances, automobile, toy
In manufacture etc. industry.But the heat resistance of polyethylene, chemical resistance be not good, limit it and use, it is therefore desirable to its property
It can be improved.Nylon 1012 is a kind of new long carbon chain nylon, has the advantages that fusing point is high, water absorption rate is small, intensity is high, has
People attempts to be modified polyethylene with Nylon 1012 processing, but compatibility between the two is bad, causes modified effect poor.To this
People attempt to add the interfacial characteristics using compatilizer improved between the two, achieve preferable effect, but with to product
The continuous lifting that can be required, the using effect of compatilizer has also been absorbed in bottleneck, has needed a kind of new process badly to carry out it
It is further to improve.
The content of the invention
The purpose of the present invention is that there is provided a kind of system of the modified poly ethylene of household electrical appliance production the problem of being directed to existing
Make technique.
The present invention is achieved by the following technical solutions：
A kind of manufacture craft of the modified poly ethylene of household electrical appliance production, comprises the following steps：
（1）First by high density polyethylene (HDPE), Nylon 1012 resin, maleic anhydride grafted polyethylene according to mass ratio 45 ~ 50：18~23：
0.5 ~ 2 is mixed, and is then delivered in high speed mixer, and the rotating speed for controlling batch mixing is 1800 ~ 2000 revs/min, mixing treatment 6
Pellet is made after ~ 8min standby；
（2）By step（1）Obtained pellet delivers melting extrusion in double screw extruder, the one of control double screw extruder
The temperature in area to 5th area is respectively：200 ~ 204 DEG C, 208 ~ 212 DEG C, 220 ~ 224 DEG C, 232 ~ 236 DEG C, 240 ~ 244 DEG C, extrude
Take out standby into rear；
（3）By step（2）The semi-finished product of gained are put into insulating box after extrusion, and it is 150 ~ 160 first to keep the temperature in insulating box
DEG C, 13 ~ 15min of isothermal holding persistently carries out a radiation treatment, then regulating thermostatic case again during being incubated herein to semi-finished product
Interior temperature is 70 ~ 80 DEG C, and 20 ~ 23min of isothermal holding persistently carries out secondary radiation treatment during being incubated herein to semi-finished product,
After the completion of take out and naturally cool to after room temperature and get product.
Further, step（2）Described in the temperature in an area to 5th area of double screw extruder be respectively：202℃、
210℃、222℃、234℃、242℃。
Further, step（3）Described in a radiation treatment be utilize electron-beam accelerator carry out radiation treatment, control
The close rate of system irradiation is 6 ~ 8kGy/min.
Further, step（3）Described in secondary radiation treatment be equally using electron-beam accelerator carry out irradiation at
Reason, the close rate for controlling irradiation is 2 ~ 4kGy/min.
The present invention is adjusted in the making of polyethylene to its composition, and its manufacture craft is improved, its
In maleic anhydride grafted polyethylene with the addition of in its composition improve high density polyethylene (HDPE) and Nylon 1012 tree as compatilizer
Compatibility between fat so that nylon in good dispersion of the Nylon 1012 in high density polyethylene (HDPE), the semi-finished product after melting extrusion
1012 are filled in high density polyethylene (HDPE) in filament shape, and the characteristic such as overall heatproof, water-fast, intensity is relatively not added with compatilizer lifting
Substantially, now obtained semi-finished product have had a good characteristic basis, but in order to further enhance its performance, but to extrusion after
Semi-finished product carried out radiation treatment, radiation treatment is divided into two stages progress, and the first stage control temperature for 150 ~ 160 DEG C,
Carry out a radiation treatment, the interface of the electron beam irradiation now carried out mainly to Nylon 1012 and high density polyethylene (HDPE) between the two
Handled, further improve cross-link intensity between the two, second stage controls temperature to be 70 ~ 80 DEG C, carries out secondary irradiation
Processing, the electron beam irradiation now carried out is mainly handled Nylon 1012 and the respective strand of high density polyethylene (HDPE), carried
The cohesion energy density of two components has been risen, the resistance of motion of strand is enhanced, the use characteristic of two components is enhanced, it is final effective
Improve end properties.
The present invention has advantages below compared with prior art：
Rational allocation of the present invention material composition, while manufacture craft is improved again, final obtained modified poly ethylene raw material tool
There are good heatproof flame-retardant, a water-oil resistance, the mechanical characteristic such as intensity also has good lifting, solves and exists in the prior art
Polythene material be modified bottleneck problem, great popularization practical value.
