Description
Technical field
The present invention relates to PET engineering plastics technical fields, it is more particularly related to a kind of permanently antistatic
PET engineering plastics.The invention further relates to a kind of preparation method of permanently antistatic PET engineering plastics.
Background technology
PET plastic molecular structure high degree of symmetry, has certain crystalline orientation ability, so with higher film forming and
Mouldability.Since the eighties, PET has breakthrough progress as engineering plastics, sequentially develops nucleator and crystallization promotes
Agent, PET and PBT become one of five large-engineering plastics together as thermoplastic polyester at present.Since PET resin material price is low,
It is even also cheaper than general-purpose plastics price, so PET modified materials emerge in an endless stream in recent years.
The main turnover for applying to the products such as electronic component, chip, lithium battery of permanently antistatic packaging is packed for, when
It is preceding mainly mainly to be prevented using the plastic uptake product of HIPS, PP base material, antistatic scheme using addition conductive carbon black and polyethers
The method of electrostatic agent.At present, the method for carrying out antistatic treatment for high molecular material has very much, generally speaking, can be divided into
Two classes：First method is：Conductive filler is added, such as, carbon black, carbon nanotubes, copper powder etc.；Second method is：Add anti-
Electrostatic agent or conducting polymer, such as, cetyl trimethylammonium bromide, polyaniline, polyether ester amides etc..But this two class changes
Property method there is it is respective the shortcomings that：Conductive filler is easily reunited, difficulties in dispersion, while additive amount is more, improves material cost；
Antistatic additive or conducting polymer can be migrated with the growth of time and to outer surface, are lost in, be resisted quiet due to migration
Electric persistence is poor.
PET permanently antistatics sheet material mainly uses the method for secondary coating at present, and one layer of antistatic coating is applied on surface,
The method has the shortcomings that very much, for example coating liquid uses the environmental issue of solvent, and thin layer Coating Durability problem is secondary
Process production efficiency problem brought etc..If permanently antistatic is prepared by interior plus conductive filler or antistatic additive
PET material, however it remains the problem of conductive filler disperses non-uniform problem and poor antistatic additive persistence.
The Chinese patent of 104845271 A of Patent No. CN discloses a kind of PET/PTT materials of antibiotic antistatic functionalization
Material, improves the antistatic property of PET/PTT materials, HKD-912 is a kind of sulphonic acids by adding antistatic additive as HKD-912
