Description
Technical field
The present invention relates to polymeric material field, be specifically related to a kind of switch special nylon material and preparation method thereof.
Background technology
The material of switch is selected very crucial, because be short-circuited or electric current causes more greatly switch temperature mistake at circuitGao Shi, switch can melt even catching fire, on the market, often adopts nylon material to manufacture the mould of switch insideTool.
Nylon is one of three large synthetic fibers, because its thermodynamic property is good, and light weight and corrosion-resistant, and extensively shouldFor the manufacture of industry. But, fact proved in recent years, nylon material also exists that anti-flammability is bad, mechanical strength notThe shortcomings such as height, notched Izod impact strength is low, heat distortion temperature is not high. Therefore, nylon product is improved more nextMore come into one's own.
Summary of the invention
In view of above-mentioned information, one of object of the present invention is to provide a kind of high voltage withstanding, good opening of fire resistanceClose special nylon material.
Another object of the present invention is to provide a kind of preparation method of above-mentioned switch special nylon material.
Technical scheme of the present invention is that a kind of switch special nylon material, by mass percentage by following component groupBecome: nylon resin 75～80%, polyimides 5～10%, silicate 3～5%, lubricant 3～10%, auxiliary agent6～14%。
Described nylon resin is polycaprolactam PA6.
Described silicate is CaSiO3。
Described lubricant is dolomol.
Described auxiliary agent is nano imvite, bentonite, mica, kaolin, talcous one or more mixedCompound.
A preparation method for above-mentioned switch special nylon material, comprises the following steps: by nylon resin, polyamidesAfter imines, silicate, lubricant and auxiliary agent mix, add in double screw extruder and melt extrude, extrudeTemperature be 200～240 DEG C, screw speed is 400rpm; Finally to the material of extruding carry out cooling, air-dry,Pelletizing, the strong magnetic of mistake, packaging, obtain switch special nylon material finished product.
A kind of switch special nylon material provided by the invention, fire resistance synergy is obvious, and mechanical performance is good,Can use in daily life with in producing more safely and effectively.
