Abstract
The invention relates to conductive nylon which comprises the following components in parts by weight: 40-70 parts of polyamide fibers, 3-8 parts of an interface coupling agent, 3-10 parts of a toughening agent, 0.5-1.0 part of a disperse lubricating agent, 5-10 parts of vanadium dioxide and 10-15 parts of tin dioxide. The conductive nylon is excellent in conductivity and can be widely used for manufacturing auto parts in the automobile industry, parts in the household appliance industry, parts in the building decoration industry, daily necessities such as safety helmets, motorcycle baffles, shoe heels, snow sports products, toys, clocks, sound box shells, suitcases, buttons and cosmetic boxes, and advertisement products such as nameplates and decorations.
Description
Technical field
The present invention relates to the nylon field, specifically, the present invention relates to a kind of conductive nylon.
Background technology
Tynex is commonly called as nylon, its purposes is very extensive, automotive industry is usually used in making automobile component such as dashboard, vehicle-body outer panel, inner trim panels, bearing circle, insulating board, door lock, collision bumper, vent-pipe etc., household electric appliances are usually used in making such as refrigerator, televisor, washing machine, vacuum cleaner, food mixer, the housing of telephone set etc., be usually used in making such as sanitary apparatus at architectural decoration, the swimming pool lining, tubing and pipe fitting etc. are in addition also for the manufacture of safety helmet, the motorcycle plate washer, heel, the snowfield sporting goods, toy, clock, casing of loudspeaker box, suitcase, button, daily necessities and the nameplates such as minaudiere, the advertising matters such as ornament.
Although tynex is widely used, because the characteristic of the molecular structure performance of tynex own, so that tynex is not enough aspect electroconductibility.

Conductive nylon of the present invention has excellent electroconductibility, can be widely used for automotive industry and be usually used in making daily necessities and the advertising matters such as nameplate, ornament such as automobile component, household electric appliances, architectural decoration, safety helmet, motorcycle plate washer, heel, snowfield sporting goods, toy, clock, casing of loudspeaker box, suitcase, button, minaudiere.
Embodiment
Below the invention will be further described for the description by embodiment, but this is not to be limitation of the present invention, those skilled in the art are according to basic thought of the present invention, can make various modifications or improvement, but only otherwise break away from basic thought of the present invention, all within the scope of the present invention.
Embodiment 1
It is lower dry 4 hours in 90 ℃ to take by weighing 600 tynexs that restrain, then with vanadium dioxide 80 grams, tindioxide 130 grams, γ-aminopropyl triethoxysilane 50 grams, MBS 50 grams and glyceryl monostearate 8 grams, in homogenizer, stirred 5 minutes with 1100 rev/mins, after evenly, emit.To add length-to-diameter ratio (L/D) be in 40 the twin screw extruder mixing equal materials of spoon, the processing temperature of twin screw extruder: 180 ℃ of district's temperature, two district's temperature are 185 ℃, three district's temperature are 195 ℃, and four district's temperature are 210 ℃, and five district's temperature are 215 ℃, six district's temperature are 225 ℃, seven district's temperature are 235 ℃, and eight district's temperature are 240 ℃, and engine speed is 320 to turn/min; Cool off check rod, air-dry pelletizing through after extruding, namely prepare conductive nylon of the present invention.
Embodiment 2
According to preparing conductive nylon with embodiment 1 identical mode, difference is not use vanadium dioxide.
Embodiment 3
According to preparing conductive nylon with embodiment 1 identical mode, difference is not use tindioxide.
Experimental example
Carry out test surfaces resistivity by the IEC60093 requirement, the result is as follows: the surface resistivity of the conductive nylon of embodiment 1 (Ω) is 1.5 * 10
4, the surface resistivity of the conductive nylon of embodiment 2 (Ω) is 4.3 * 10
6, the surface resistivity of the conductive nylon of embodiment 3 (Ω) is 3.6 * 10
6Surface resistivity is larger, illustrates that electroconductibility is lower.This shows, add vanadium dioxide and tindioxide and produced unexpectedly synergy.
