Obtain modified micaceous powder.
The mica powder diameter is 60-80nm.
The butyl acrylate, the mica powder, the sodium peroxydisulfate, the demulsifier and described ten in step (1)
The mass ratio of dialkyl benzene sulfonic acids sodium is (16-20): (40-60): (0.3-0.5): (1-3): (0.1-0.3).
The demulsifier in step (1) is iron chloride or aluminium chloride.
Specific preparation process is as follows for the antibacterial agent:
(1) molecular sieve is added in three-necked flask, and is configured to solution with deionized water, is placed in water-bath, 80-100
Start to stir under the conditions of DEG C；
(2) a certain amount of Zn (NO is successively added into solution3)2With Cu (NO3)2Solution reacts 4-6h；
(3) after reaction, suspension is filtered, and utilizes deionized water washing precipitate repeatedly；
(4) obtained sediment is put into drying box, 100-120 DEG C of dry 20-24h is to get the antibacterial agent.
Zn (NO in step (2)3)2With Cu (NO3)2Mass ratio be (4-6): (6-9).
The antioxidant is three (2,4- di-t-butyl) phenyl-phosphites, four [β-(3,5- di-tert-butyl-hydroxy phenyl)
Propionic acid] pentaerythritol ester or 1,3,5- trimethyls -2,4, one of 6- (3,5- di-t-butyl -4- hydroxyphenylmethyl) benzene or several
The mixing of kind.
The compatilizer is SEBS-g-MAH.
A kind of preparation method of any of the above-described high-performance antibiosis PP-PA6 composite material, comprising the following steps:
(1) 80 parts of -100 parts of PP, 20 parts of -30 parts of PA6,1 part of -3 parts of POE, 16 parts -20 parts modified micaceous powder, 4 part -6 are weighed
Part antibacterial agent, 0.1 part of -0.5 part of antioxidant, 0.1 part of -0.3 part of SEBS-g-MAH are mixed and stirred for uniformly, obtaining mixture；
(2) by mixture extruding pelletization obtained in step (1) to get arrive PP-PA6 composite material.
Preferably, the step (2) specifically: use double screw extruder extruding pelletization, wherein the twin-screw extrusion
Machine includes six humidity provinces sequentially arranged, 180~200 DEG C of area's temperature, two 240~260 DEG C of area's temperature, three area's temperature 240
~260 DEG C, four 240~260 DEG C of area's temperature, five 240~260 DEG C of area's temperature, six 240~260 DEG C of area's temperature, head temperature 240
~260 DEG C, 200~280r/min of screw speed.
The beneficial effects of the present invention are:
1, mica powder passes through the grafting of butyl polyacrylate (PBA), can form the organic coating of PBA on mica powder surface
Layer produces powerful stereoscopic protective effect, prevents the reunion of mica powder, can be homogeneously dispersed in PP-PA6 matrix,
Improve the mechanical property of PP-PA6 composite material.
2, the addition of antibacterial agent improves PP-PA6 anti-microbial property.
