Convenient, stacking neatly, is convenient for management.The frame of SMT loading and unloading in the past uses BMC as raw material, but not environmentally.Existing market is wide
The SMT loading and unloading frame raw material of use has the conductive charcoal of the fibre reinforced ABS, Japanese NIKKO-RACK of Panasonic Japan and Asahi Chemical Industry
The HIPS of black filling.But these material heatproofs are at 110 DEG C hereinafter, can also in long-term use process (under vibration, hygrothermal environment)
Generate conductive filler removing and obscission.Therefore, the conductive PP Pipe Compound for developing new heat-resistant, wear-resistant consumption has urgent market
Demand.
Polybutylene terephthalate (PBT) (PBT) and polyethylene terephthalate (PET) are hairs the 1970s
The thermoplastic polyester that exhibition is got up, using the PBT/PET alloy of blend method preparation have high intensity, the good, heatproof of rigidity, moisture-proof,
Solvent resistant and low-cost feature, automobile and in terms of be widely applied.
Carbon nanotube has good conductive property, few as conductive filler additive amount, influences smaller, table to resin property
Face glossiness is good, will not occur the phenomenon that falling black powder in finished product use process, and plays in use net well
Change effect.
Blending method is the most common method for preparing carbon nano-tube/polymer based composites.This method is by carbon nanometer
Pipe is dispersed directly into polymeric matrix.Since carbon nanotube is easily reunited, it is surface-treated.Common surface changes
Property agent have: silane, titanate coupling agent, stearic acid and high molecular surfactant etc., in addition to this, also can be used dispersing agent and
Ultrasonic wave etc. is subject to aid dispersion.The advantages of blending method is simple and easy, large-scale industrial production easy to accomplish, without spy
Different equipment, each component ratio are easily controllable.The disadvantage is that component is not easy to be uniformly dispersed, it is easy to happen reunion.Carbon nanotube itself
Specific surface area is larger, and surface can be very high, is very easy to reunite, greatly limits its application.
CN102532823A discloses a kind of antistatic PBT material, comprising PBT, glass fibre, carbon nanotube, antioxidant,
Lubricant, toughener, the patent are not directed to the surface treatment and the dispersion of carbon nanotube.

Energy filler, with the direct melt blending such as PET/PTT, resulting composite material has thermally conductive and anti-static function simultaneously.Its carbon is received
Mitron is to first pass through conventional strong oxidizer processing, then with coupling agent treatment, process is cumbersome, and strong acid treatment may damage carbon
The self structure of nanotube.Antistatic PET engineering plastics disclosed in CN103183934A are also to use similar approach.
CN102675836A discloses a kind of preparation method of conduction/antistatic polyester PET composite material, which uses
Conductive powder carbon nanotube and aniline and PET pellet are subjected to solution blending, conduction/antistatic polyester PET composite material is made,
But solution blending is suitable only for the preparation of a small amount of composite material, is not suitable for large-scale production.
