The plasticizer is to include phthalic acid ester, terephthalate, fatty group dibasic acid, glycol dibenzoate One or more in ester, citrate, phosphate, chloralkane, benzene polycarboxylic acid's ester, sulfonamide.
The solid additive is polytetrafluoroethylene (PTFE).
Present invention also offers a kind of preparation method according to elevator traction system adjuvant of the present invention, including with Lower step：
1st, lubricant, increasing grinding agent, metal antirusting agent are premixed into 5-10 minutes in mixer；
2nd, modification of nylon, antioxidant, plasticizer, solid additive are kneaded in banbury, are heated up to 220-230 DEG C, Banburying 10-20 minutes；
3rd, lubricant, increasing grinding agent, metal antirusting agent premix are squeezed into banburying chamber, continues banburying 15-25 minutes；
4th, banburying material is matched by single screw extrusion machine extrusion molding, shape and the traction sheave groove profile of extrusion neck ring mold, extrusion Shaped article is finished product traction system adjuvant after air-cooled, winding.
The elevator traction system adjuvant produced through above-mentioned operation, can directly be fitted in the traction groove of traction sheave.This is auxiliary Auxiliary agent can be well the permeability environment adapted between steel wire rope and traction sheave, can by the proportioning for adjusting lubricant with increasing grinding agent Stable coefficient of friction is provided for elevator traction system, reduces skidding.Also protective layer can be formed in traction rooved face simultaneously, Steel wire rope and traction sheave are effectively protected, extend its service life.
Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with specific embodiment to this hair It is bright to be described in further detail.
Embodiment 1：
By 5 parts of crystalline flake graphite, 3 parts of nano silicon and metal antirusting agent heptadecenyl imidazolidene succinate with 3 parts of the composition of synthesis barium sulfonate premixes 8 minutes in mixer；By modification of nylon (BASF Corp. of Germany, trade mark A3Z) 75 In part, 11 parts of polytetrafluoroethylene (PTFE), 2 parts of terephthalate, octyl group -1 part of butyl diphenylamines addition banbury, in 225 DEG C of temperature Lower banburying 15 minutes；The premix of crystalline flake graphite, nano silicon and metal antirusting agent is squeezed into banburying chamber, insulation continues Banburying 15 minutes；Banburying material is extruded from single screw extrusion machine, traction system adjuvant A is produced after air-cooled, winding.
Embodiment 2：
5 parts of 4 parts of molybdenum disulfide, 5 parts of nano aluminium oxide and phosphosulfurized olefin calcium salt are premixed 5 minutes in mixer；Will 72 parts of modification of nylon (du pont company, trade mark Elvamide 8061), 12 parts of polytetrafluoroethylene (PTFE), 1.5 parts of citrate, 2, In 0.5 part of addition banbury of 6- di-tert-butyl-4-methy phenols, banburying 12 minutes at a temperature of 230 DEG C；By molybdenum disulfide, receive The premix of rice aluminum oxide and phosphosulfurized olefin calcium salt is squeezed into banburying chamber, and insulation continues banburying 15 minutes；By banburying material from list Extruded in screw extruder, traction system adjuvant B is produced after air-cooled, winding.
According to GB 7588-2003《Elevator manufactures and installation safety standard》In regulation, use rated load for 1000kg, normal speed 1.75m/s, the elevator of wrap angle sigma=158 ° of steel wire rope on the traction sheave carry out urgent stop experiment, When car is loaded with 125% rated load and run downwards with normal speed, operational brake makes traction machine shut down, and measures steel Cord skidding distance.
According to GB 8903-2005《Steel wire rope for elevator》The method measuring steel wire rope diameter of middle offer：Clamped using with width The vernier caliper measurement of mouth, the width minimum of its jaw will be enough to cross over two adjacent stocks, and measurement should be steel wire rope end head Carried out on straight position outside 15m, at a distance of at least in 1m two sections, and same section it is orthogonal measure two numbers Value, the measured diameter of the average value of four measurement results, as steel wire rope.
Added with elevator traction system adjuvant A, B and plus under adjuvant operating mode carrying out 2000 less urgent stops examinations respectively Test, the skidding distance and diameter change of measuring steel wire rope, specific test result see the table below 1 respectively：
The urgent stop experimental test result of the elevator wire rope of table 1
Test event Adjuvant A Adjuvant B Not plus adjuvant
Average slip distance/m 0.35 0.31 1.25
Skidding distance coefficient of dispersion/% 2.55 4.62 22.61
Abrasion condition/mm 0.32 0.28 1.40
As shown in Table 1, adjuvant A and B are added in the traction groove of traction sheave, skidding distance, which is significantly shorter than, to be not added with aiding in Agent operating mode, and the coefficient of dispersion of skidding distance test result is also smaller, has stable coefficient of friction.Meanwhile on the traction sheave After adding adjuvant, the diameter change situation of steel wire rope, which is also significantly less than, is not added with adjuvant operating mode, it can be seen that adjuvant has Help extend the service life of steel wire rope and traction sheave.
Disclosed above is only several specific embodiments of the application, but the application is not limited to this, any no essence The change of innovation, it should all fall in the protection domain of the application.
