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 nylon field, specifically, the present invention relates to a kind of conductive nylon.
Background technology
Tynex is commonly called as nylon, its purposes widely, automotive industry is usually used in manufacturing automobile component 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 manufacturing as refrigerator, televisor, washing machine, vacuum cleaner, food mixer, the housing etc. of telephone set, be usually used in manufacturing as sanitary apparatus at architectural decoration, swimming pool lining, tubing and pipe fitting etc., in addition also for the manufacture of safety helmet, motorcycle plate washer, heel, snowfield sporting goods, toy, clock, casing of loudspeaker box, suitcase, button, the daily necessities such as minaudiere and nameplate, the advertising matters such as ornament.
Although tynex is widely used, due to the characteristic of the molecular structure performance of tynex own, make tynex not enough in electroconductibility.
Summary of the invention
The object of the present invention is to provide a kind of conductive nylon.
In order to realize object of the present invention, the invention provides a kind of conductive nylon, comprising the component of following weight parts:
Tynex 40 ~ 70 weight part;
Interface coupling agent 3 ~ 8 weight part;
Toughner 3 ~ 10 weight part;
Dispersed lubricant 0.5 ~ 1.0 weight part;
Vanadium dioxide 5 ~ 10 weight part;
Tindioxide 10 ~ 15 weight part.
Preferably, described interface coupling agent is one or more in γ-aminopropyl triethoxysilane (KH550), γ-glycidyl ether oxygen propyl trimethoxy silicane (KH560), γ-(methacryloxypropyl) propyl trimethoxy silicane (KH570), tynex grafted maleic (tynex-g-MAH), styrene-maleic anhydride copolymer (SMA), Research of Grafting Malaic Anhydride Onto Polyethylene (LDPE-g-MAH), linear low density polyethylene grafted maleic anhydride (LLDPE-g-MAH), diglycidyl ether type epoxy resin.
Preferably, described toughner is MBS (MBS), MBS, hydrogenated styrene/Butadiene/Styrene) one or more in segmented copolymer (SEBS).
Preferably, described dispersed lubricant is one or more in glyceryl monostearate, Tristearoylglycerol, ethylene bis stearamide, the two laurylamide of ethylene, the two amine hydroxybenzene of ethylene, lower molecular weight ionomer, ethylene-acrylic acid copolymer, ethylene-vinyl acetate copolymer.
More preferably, conductive nylon of the present invention comprises the component of following weight parts:

Vanadium dioxide 8 weight part;
Tindioxide 13 weight part.
Conductive nylon of the present invention has excellent electroconductibility, can be widely used for automotive industry and be usually used in manufacturing 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 by way of the description of embodiment, the invention will be further described, but this is not limitation of the present invention, those skilled in the art are according to basic thought of the present invention, various amendment or improvement can be made, but only otherwise depart from basic thought of the present invention, all within the scope of the present invention.
Embodiment 1
The tynex taking 600 grams at 90 DEG C dry 4 hours, then with vanadium dioxide 80 grams, tindioxide 130 grams, γ-aminopropyl triethoxysilane 50 grams, MBS 50 grams and glyceryl monostearate 8 grams, stir 5 minutes with 1100 revs/min in homogenizer, release after evenly.It is in the twin screw extruder of 40 that the material of the equal spoon of mixing is added length-to-diameter ratio (L/D), the processing temperature of twin screw extruder: district's temperature 180 DEG C, two district's temperature are 185 DEG C, three district's temperature are 195 DEG C, and four district's temperature are 210 DEG C, and five district's temperature are 215 DEG C, six district's temperature are 225 DEG C, seven district's temperature are 235 DEG C, and eight district's temperature are 240 DEG C, and engine speed is 320 turns/min; After extruding, cool check rod, air-dry pelletizing, namely prepare conductive nylon of the present invention.
Embodiment 2
Prepare conductive nylon according to the mode identical with embodiment 1, difference is not use vanadium dioxide.
Embodiment 3
Prepare conductive nylon according to the mode identical with embodiment 1, difference is not use tindioxide.
Experimental example
Carry out test surfaces resistivity by IEC60093 requirement, result is as follows: the surface resistivity (Ω) of the conductive nylon of embodiment 1 is 1.5 × 10
4, the surface resistivity (Ω) of the conductive nylon of embodiment 2 is 4.3 × 10
6, the surface resistivity (Ω) of the conductive nylon of embodiment 3 is 3.6 × 10
6.Surface resistivity is larger, illustrates that electroconductibility is lower.As can be seen here, add vanadium dioxide and tindioxide to create and act synergistically unexpectedly.
