Description
Technical field
The invention belongs to technical field of polymer materials, particularly relates to a kind of scratch-resistant PBT-PA66 composite materials.
Background technology
Polybutylene terephthalate (PBT) (PBT) is a kind of important thermoplastic polymer, good stability of the dimension, insulating properties
Good, oil resistant, is widely used in the fields such as household electrical appliance, mechanical fitting, office appliance and Communication Equipment.Polyamide 66 (PA66) is made
For the engineering plastics with certain polarity, the fields such as chemical industry, building materials, household electrical appliances, automobile are also widely used for.
Since two kinds of materials of PBT and PA66 have certain complementation, we can synthesize PBT-PA66 composite materials.But
The molecular chain structure of PBT and PA66 is there is many differences, their compatibility is bad, and scraping and wiping resistance performance is also general, this limitation
The extensive uses of PBT-PA66 composite materials.
The content of the invention
The object of the present invention is to provide a kind of scratch-resistant PBT-PA66 composite materials, to solve the raising PBT of the prior art
The problem of with the compatibility of PA66 and improving the scraping and wiping resistance performance of PBT-PA66 composite materials.
The present invention is achieved by the following technical solutions：
A kind of scratch-resistant PBT-PA66 composite materials, are made of the component of following parts by weight：
Nanometer MoS after the processing2To pass through the nanometer MoS after coupling agent KH570 processing2。
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.
Nanometer MoS2Mass ratio with coupling agent is 5-10: 2-4.
Nanometer MoS after the processing2Preparation method, comprise the following steps：
1) the nanometer MoS of set amount is weighed2It is added in ethanol, adds the coupling agent KH570 of set amount；The nanometer
MoS2Mass ratio with coupling agent is 5-10: 2-4；When ultrasonication 1-2 is small, it is added dropwise between vinegar acid for adjusting pH value 3-5；
2) it is fixedly separated after cooling by the mixed liquor of step 1) when 60-80 DEG C of constant temperature stirring 6-8 is small, then in 100-
The nanometer MoS being dried to obtain in 120 DEG C of vacuum drying chamber after processing2。
The beneficial effects of the invention are as follows：
Nanometer MoS provided by the invention2After silane coupling agent KH570 processing, it can be better dispersed in PBT-PA66,
This is conducive to the physical property and crocking resistance that strengthen PBT-PA66 composite materials.
Nanometer MoS2Tool has a layered construction, and Relative sliding can occur between its lamella under the shear action of frictional force,
And transfer membrane can be generated in material surface, the direct contact and friction of sliding surface are reduced, so as to improve the rub resistance ability of material.
The epoxide group of epoxy resin can be reacted with the amino (- NH2) of PA66, contact surface formed epoxide group with
The copolymer of PA66, reduces the tension force between PA66 and PBT, improves compatibility between the two, the physical property of reinforcing material.
