Background technique
Polyamide 6 (PA6) is a kind of important thermoplastic polymer, and good stability of the dimension, insulating properties is good, oil resistant, extensively
Applied to fields such as household electrical appliance, mechanical fitting, office appliance and Communication Equipments.As the improvement of people's living standards, to making
Material has increasingly higher demands, in some special fields, such as automotive material, to the antistatic property of PA6
There is a degree of requirement with VOC (volatile organic compounds) performance.
PA6 composite material VOC performance difference is following aspect: firstly, PA6 raw material are in the synthesis process, there are more small
Molecular impurity, this will lead to increasing for VOC numerical value；Secondly, PA6 composite material is in process, various phases are often added
Hold agent, these compatilizers are often converted into small-molecule substance when heating to some extent, lead to increasing for VOC numerical value.
Summary of the invention
The object of the present invention is to provide a kind of antistatic low VOC polyamide 6 composite materials and preparation method thereof, existing to solve
The problem of the VOC high of the PA6 composite material of technology.
The present invention is achieved by the following technical solutions:
A kind of antistatic low VOC polyamide 6 composite material, is made of the components of following parts:
The absorption master batch includes polypropylene and mica.
The mass ratio of the polypropylene and mica is 40-60:6-10.
The antioxidant is three (2,4- di-t-butyl) phenyl-phosphites, four [β-(3,5- di-tert-butyl-hydroxy phenyl)
Propionic acid] one of pentaerythritol ester or 1,3,5- trimethyl -2,4,6- (3,5- di-t-butyl -4- hydroxyphenylmethyl) benzene or more
Kind.
The lubricant is the combination of one or both of calcium stearate or stearic acid sodium.
The preparation method of the absorption master batch, comprising the following steps:
1) polypropylene and mica are adequately mixed according to the ratio, polypropylene pre-expanded particles is squeezed out in extruder；
The mass ratio of the polypropylene and mica is 40-60:6-10；
2) using normal heptane as foaming agent, polypropylene pre-expanded particles made from step 1) are foamed, it is poly- that foaming is made
Propylene；
3) expanded polypropylene and water are mixed 5-10 minutes in super mixer, is prepared into absorption master batch.
The mass ratio of the normal heptane and polypropylene pre-expanded particles is 50-90:60-80.
Treated the dilute preparation method of graphite oxide, comprising the following steps:
1) dilute water-soluble of graphite oxide is formed to the dilute middle addition deionized water of graphite oxide, after ultrasonic reaction 20-30 minutes
Liquid；
2) cetylamine and dehydrated alcohol are weighed, is added in the dilute aqueous solution of graphite oxide, in 100-120 DEG C of oil bath pan
Under environment, back flow reaction 20-24 hours；
3) product in step 2) is filtered, is placed in 60-80 DEG C of vacuum tank dry 20-24 hours up to after handling
Graphite oxide it is dilute；
The graphene oxide and the mass ratio of the deionized water are 60-80:20-30；
The mass ratio of the cetylamine, the dehydrated alcohol and the graphene oxide water solution is 10-30:5-11:70-
90。
The preparation method of the antistatic low VOC polyamide 6 composite material of any of the above-described, comprising the following steps:
1) weigh parts by weight be 60 parts -80 parts of PA6,1 part -5 parts of absorption master batch, 0.1 part -0.5 part of antioxidant and
0.4 part -0.8 part of lubricant, 16 parts -24 parts treated that graphene oxide is mixed and stirred for uniformly, obtaining mixture；
2) by mixture extruding pelletization obtained in step 1) to get arrive PA6 composite material.
Above-mentioned steps 1) in each raw material before mixing respectively dry 5 hours at 100 DEG C.
The step 2) specifically:
Mixture obtained in step 1) is put into extruding pelletization in the hopper of double screw extruder, wherein described double
Screw extruder includes six humidity provinces sequentially arranged, and the temperature of the first humidity province is 180 DEG C~220 DEG C, second temperature area
Temperature be 250 DEG C~290 DEG C, the temperature of third humidity province is 250 DEG C~290 DEG C, the temperature of the 4th humidity province is 250 DEG C~
290 DEG C, the temperature of the 5th humidity province is 250 DEG C~290 DEG C, and the temperature of the 6th humidity province is 250 DEG C~290 DEG C, double spiral shells
The head temperature of bar extruder is 250 DEG C~290 DEG C, and screw speed is 120r/min~300r/min.
The beneficial effects of the present invention are:
The technical program is connect by way of chemical bonding on surface using the oxygen-containing functional group on the surface of graphene oxide
Branch suitable long chain alkane, long chain alkane can effectively stop the reunion of graphene, and graphene can be better dispersed in
