Description
Technical field
The present invention relates to a kind of wide warm wire-rope greases of elevator, belong to lubrication technical field.
Background technique
With the development of economic construction of China and the adjustment of the industrial structure, requirement of the wirerope user to rope grease is more next
It is higher, rope grease is not required nothing more than with good protective performance, also requires dropping point high, adhesive force is strong, will not to ambient enviroment
Cause adverse effect.
Elevator wire rope does not need only to have biggish coefficient of friction, has certain auxiliary to make the braking system of elevator
With, prevent from skidding between wirerope and pulley, and use in main elevator indoors, elevator do not take temperature,
In the case of the measure of humidity regulation, elevator internal environment and their location integrated environment are closely related, such as the Northeast's low temperature
Dry, the coastal south hot humid, this region temperature, humidity difference are very big, while elevator will carry certain bear
It carries.
Thus steel wire rope for elevator producer proposes that lubricating grease need to have good extruding to increase mill effect and high/low temperature requirement,
It also requires lubricating grease that there is good adhesion, permeability, antirust, anti-corrosive lubricity, pollution surrounding enviroment is prevented, convenient for cleaning.
Many people improve this, as CN102827678A is " a kind of to combine with lubrication with the rope grease of antirust double effects
Object " based on calcium sulfonate complex grease, ceresine improves the rustless property of wirerope, using low temperature -20 as additive
DEG C, it is mainly used in ocean operation environment；Such as CN108531258A " a kind of elevator wire rope lubricating grease ", CN106467792A
" a kind of elevator wire rope lubricating grease and preparation method thereof ", CN103436329B " a kind of elevator wire rope lubricating grease and its preparation
Method ", by be added other additives reach increasing rub, the functions such as antirust.CN105733752B " hot painting type elevator wire rope rouge and
Its preparation method " it is added microwax and amides thickening agent and antirust agent, increasing rub agent etc., make it have good film forming and metal
Surface adhesion force and frictional behaviour.
Summary of the invention
The object of the present invention is to provide a kind of wide warm wire-rope greases of elevator.
Realizing the technical solution of the object of the invention is: a kind of wide warm wire-rope grease of elevator, by weight percentage
Number meter, including following component: first foundation oil 21.5-30, the second base oil 2.57-7.72, microwax 10-20, synthetic wax 20-

Sour 0.09-0.27, calcium hydroxide 0.08-0.24.
Further, first foundation oil is any one in extraction oil and rubber oil, and it is polycyclic for extracting the main component of oil out
Aromatic hydrocarbons, 100 DEG C of kinematic viscosity is in 15-40mm2/ s, wherein it is preferred that 100 DEG C of kinematic viscosity is in 25-35 mm2The extraction of/s
Oil；The main component of rubber oil has paraffinic base, naphthenic base, three kinds of aryl, and 100 DEG C of kinematic viscosity is in 15-40mm2/s,
Wherein preferably 100 DEG C of kinematic viscosity is in 25-35 mm2The rubber oil of/s.
Second base oil is any one in PAO40, G250N and 150BS.
Further, the composition of microwax is other than n-alkane, also containing a large amount of macromolecule isoparaffins and with length
The cycloalkane of chain, microwax include 75# microwax, 80# microwax, 87# microwax, preferably 80# microwax.
Further, synthetic wax has a Fischer-Tropsch wax, husky rope wax, polyethylene wax, preferably 95# Fischer-Tropsch wax and fusing point be 110 DEG C with
On polyethylene wax is a kind of or mixing.
Further, tackifier have hydrogenated isoprene ethylene propylene copolymer, ethylene-propylene copolymer, polyisobutene and poly- third

Compared with prior art, the invention has the advantages that
(1) the semifluid wire rope fiction drive that certain consistency is made in composite calcium sulfonate grease lubricant is added in the present invention in hydr ocarbon-based grease
Rouge improves dropping point, the waterproofness, protective performance of product, solves the high temperature trickling phenomenon and pollution atmosphere of current product
The problems such as environment, rust corrosion；Solves the problems, such as the cold cracking of product simultaneously.
(2) when the infiltration type coating of wire-rope grease of the invention, for a long time under 150 DEG C of high temperature regardless of oil, and it is long when
Between after high temperature action, be still able to maintain at 85 DEG C of high temperature and do not trickle, the performance of -40 DEG C of not embrittlement of low temperature is free of volatile solvent, applies
It is convenient to apply, and production cost is low, improves lubricant effect, can effectively meet the lubrication and requirement of shelter in the inside and outside portion of wirerope in operation.
Specific embodiment
The elevator of the present invention preparation process of wide warm wire-rope grease, includes the following steps:
1. overbased sulfoacid calcium (T106D) is added in the second base oil of 2-6%, acetic acid and water mixing are added, isothermal reaction 1-3
