Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of flame-proof abrasion-resistant nylon composite materials and preparation method thereof.
Background technology
Nylon as most important kind maximum in engineering plastics, mainly for industries such as automobile, electrical equipment, communication, electronics, machineries.Fatigue strength and the rigidity of nylon are higher, and thermotolerance is better, but its dimensional stability is inadequate, and impact resistance is poor, so many research and development scholar's research go out the higher Reinforced Nylon of some stability.
Although switch in the market pulls out the common Reinforced Nylon of the many employings of mouth, during the metal to-metal contact of these Reinforced Nylon, frictional coefficient is higher, and there is puckery zoning the time once long, and friction increases and causes silver point to melt, and current capacity declines.Meanwhile, because electrical equipment is to the increase of miniaturization and electrical equipment working current, it is quite high that the temperature of inside electric appliance element can rise, so need nylon to have anti-flaming function.Therefore how to overcome the deficiencies in the prior art, develop a kind of flame-proof abrasion-resistant and the nylon composite materials with self-lubricating function is the problem that current technical field of polymer materials needs solution badly.
Summary of the invention
The object of the invention is to solve the deficiencies in the prior art, providing a kind of flame-proof abrasion-resistant nylon composite materials and preparation method thereof, this nylon composite materials has good flame-proof abrasion-resistant performance, and has self-lubricating function.
The technical solution used in the present invention is as follows:

Further preferably described coupling agent is silane coupling agent KH570.
Further preferably described antioxidant is antioxidant 264.
The preparation method of above-mentioned flame-proof abrasion-resistant nylon composite materials, comprises the steps:
Step (1): first Nylon 66, carbon fiber, magnesium hydroxide crystal whisker, coupling agent and antioxidant are mixed in low speed mixer, obtains compound A;
Step (2): then the acid of Nano graphite powder, tetrafluoroethylene, nano zine oxide and melamine cyanogen urea is mixed in high-speed mixer, obtain compound B;
Step (3): by the compound B mixing extrusion of the compound A of step (1) gained and step (2) gained, pelletizing after cooling, screening, dehydration, obtains flame-proof abrasion-resistant nylon composite materials of the present invention.
compared with prior art, its beneficial effect is in the present invention:preparation technology of the present invention is simple, and obtained flame-proof abrasion-resistant nylon composite materials not only has good mechanical property and stability, also has good flame-proof abrasion-resistant performance, and with self-lubricating function, can be used for manufacturing various switch and pull out mouth.
