Technical field
The invention belongs to polythene material production technical field and a kind of preparation method thereof.
Background technology
Polyethylene-abbreviation PE English name: Polyethylene polyethylene (PE) is one of five large synthetic resins.Polyethylene is mainly divided into linear low density polyethylene (LLDPE), Low Density Polyethylene (LDPE), high density polyethylene(HDPE) (HDPE) three major types.Polyethylene odorless, nontoxic, feel ceraceous, has excellent resistance to low temperature (minimum use temperature can reach-70 ~-100 DEG C),
chemistrygood stability, the erosion (the not resistance to acid with oxidizing property) of the most of soda acid of ability, is insoluble to common solvent under normal temperature, inhales
waterproperty is little,
electricityexcellent insulating property; But polyethylene for environmental stress (chemistry with
machineryeffect) be very sensitive, heat-resistant aging is poor.Therefore by look mother, poly shortcoming is changed to its modification.
