Description
Technical field
The present invention relates to a kind of lubricating grease, more particularly to a kind of hot painting type elevator wire rope special grease.
Background technology
With the rapid development of national economy and the quickening of population urbanization paces, the quantity of middle-high building drastically increases
Add, also rapidly developed as the elevator of main conveyance and matched facilities and equipment, elevator wire rope becomes steel
One of with fastest developing speed and maximum product of the market demand in cord industry.Elevator wire rope operating status directly affects elevator
The safety coefficient of production efficiency and elevator.It is uniquely lubricated as elevator wire rope and Protection Product, the matter of elevator wire rope fat
Amount directly affects the operation conditions of elevator.
Rope grease be in steel wire rope production in a manner of " spraying " or " brushing " be coated on rope silk, rope strand and at
The lubricating grease on product rope surface can cure oil film in steel wire rope surface property, be protected during steel wire rope transportation and storage
It is not injured by environment, and fretting wear and lubricating action are avoided in steel wire rope operational process.This be ordinary steel wire rope grease all
The basic effect having, but as elevator wire rope fat for, in addition to this this solidification oil film will also have and larger rub
Coefficient is wiped, has certain booster action to the braking system of elevator, prevents from skidding between steel wire rope and pulley.Currently, in the market
General purpose steel cord fat prod majority there are problems that three aspect：First, friction coefficient does not reach requirement, followed by metal
Poor adhesive force, third, there are volatile solvents in composition, it is dangerous.
The prior art about elevator wire rope fat at present has defect in its ingredient various aspects：In terms of base oil,
Mainly based on the mixture of tapped oil, residue essential oil and residue slack wax, the index of base oil mainly emphasizes kinematic viscosity, does not have
Regulation is made to its component and content, and with the intensification of the level of crude oil processing, the yield of such base oil is fewer and fewer；
In terms of thickening agent, mainly based on polyethylene, polypropylene and its derivative, the molecular weight of such thickening agent and being averaged for base oil
Mass difference is larger, causes rope grease system under room temperature to be susceptible to non-uniform phenomenon so that rope grease is in steel wire rope table
The film forming in face is poor, and due protection effect is not had to steel wire rope；In terms of increasing rubs agent, the friction coefficient of current product is very
Difficulty reaches 0.25 requirement, and quality is also unstable in terms of improving elevator wire rope skin-friction coefficient, cannot play and answer
The effect of some protection and auxiliary braking；In addition, majority contains volatile solvent in the component of rope grease product, process is not only used
It is middle there are larger hidden danger, and the presence of solvent can seriously affect formation and oil film of the product in rope grease sea surface oil slick
Uniformity.The prior art for another example wire rope fiction drive oil/fat composition disclosed in CN103484218, is a kind of the thick of fatty acid salt
Change system can not achieve good film forming；The for another example lubricant oil composite disclosed in GB2095696, for a lubrication oil body
The polyolefin of system, addition improves the viscosity of product, but cannot have the function that thickening, still cannot function as good elevator steel wire
Rope grease uses.
Therefore, a kind of elevator wire rope fat how is provided so that it can which variety of problems in the prior art, raising is overcome to make
With effect, those skilled in the art's urgent problem to be solved is become.
