Abstract
The present invention relates to a kind of PS micas powder composite material and preparation method thereof, it is made of the component of following parts by weight：PS is 70 parts 90 parts；PE is 5 parts 10 parts；Modified micaceous powder is 20 parts 40 parts；Antiseptic is 6 parts 12 parts；Antioxidant is 0.1 part 0.5 part；Lubricant is 0.4 part 0.8 part.Titanate coupling agent TTS can be chemically reacted with the hydroxyl of mica surface, and mica surface is coated, so that the agglomeration between improving mica particle.Dodecyl sodium sulfate is adsorbed in its surface by electrostatic interaction, add the distance between mica particle, titanate coupling agent TTS molecules are made to react abundant with mica particle surface, so that mica no longer reunites and is uniformly dispersed in PS composite materials, this also increases the physical property of material.
Description
Technical field
The invention belongs to technical field of polymer materials, particularly relates to a kind of PS- micas powder composite material.
Background technology
Polystyrene (PS) is important thermoplastic polymer, and good stability of the dimension, insulating properties is good, water-fast, oil resistant, extensively
Applied to fields such as household electrical appliance, mechanical fitting, office appliance and Communication Equipments.
Mica is a kind of common aluminum silicate mineral, mica in structure usually in the sheet of false six sides or diamond shape,
Tabular, column crystal form, this unique crystal structure determine that mica possesses many excellent physical properties, and mica powder is used as and fills out
Material has been obtained for preferably applying in the plastic, it not only reduces the cost of high molecular products, moreover it is possible to lifts the portion of material
Divide physical property.
The content of the invention
The object of the present invention is to provide a kind of PS- micas powder composite material and preparation method thereof, to improve PS composite materials
Physical property.
The present invention is achieved by the following technical solutions：
A kind of PS- micas powder composite material, is made of the component of following parts by weight：
The preparation method of the modified micaceous powder, comprises the following steps：
1) a certain amount of mica powder, titanate coupling agent and dodecyl sodium sulfate are weighed to add into mixer, is stirred
10-20min；
2) take out mica powder dry 2-3h in 100-120 DEG C of vacuum drying chamber and both obtain modified micaceous powder.
The mica powder is phlogopite powder, and particle diameter is 5 μm -10 μm.
The mass ratio of mica powder, titanate coupling agent and dodecyl sodium sulfate in step 1) is 200-320: 3-7: 2-
4, the rotating speed of mixer is 120-300r/min, and temperature is 30-50 DEG C.
The titanate coupling agent is TTS.
The antiseptic is the silver-colored hydrotalcite of load.
Preferably, the hydrotalcite in step (1), Ag2SO4The mass ratio of solution is 10-16: 120-180.
The antioxidant is three (2,4- di-t-butyl) phenyl-phosphites, four [β-(3,5- di-tert-butyl-hydroxy phenyls)
Propionic acid] pentaerythritol ester or 1,3,5- trimethyls -2,4, one kind or more in 6- (3,5- di-t-butyl -4- hydroxyphenylmethyls) benzene
Kind.
The lubricant combines for one or both of calcium stearate or stearic acid sodium.
The beneficial effects of the invention are as follows：
Titanate coupling agent TTS can be chemically reacted with the hydroxyl of mica surface, and mica surface is coated,
So as to improve the agglomeration between mica particle.Dodecyl sodium sulfate is adsorbed in its surface by electrostatic interaction, is added
Distance between mica particle, makes titanate coupling agent TTS molecules react abundant with mica particle surface, so that mica is answered in PS
No longer reunite and be uniformly dispersed in condensation material, this also increases the physical property of material.
