Abstract
The invention relates to a screw cap with a solid lubricating coating. The lubricating coating is 15-30mum thick, and the solid lubricating paint comprises the following ingredients in percentage by weight: 2-12% of molybdenum disulfide, 3-6% of polytetrafluorethylene, 1-7% of graphite, 0-3% of graphene, 12-18% of tungsten disulfide, 8-12% of carbon monofluoride, 16-34% of epoxy resin, 18-29% of nitroresin, and 3-9% of paint additives. The lubricating coating has excellent self-lubricating property, and anti-loosening and anti-occlusion properties. The screw cap with the solid lubricating coating realizes low torque coefficient of 0.1-0.13, and high torque coefficient of 0.14-0.17, thereby meeting the special requirements of automobiles, shipbuilding, power generation and other industries on the screw cap.
Description
[technical field]
The present invention relates to a kind of nut and production method thereof with solid lubrication coat.
[background technology]
The nut Application Areas is very extensive, almost is applied to all respects of industrial circle, and year usage quantity is very huge.But the high-end nut of anti-interlock, anti-loosening, self-lubricating, also rarely found on the market, research in this respect still less.
The solid lubrication coat technology that developed countries such as America and Europe just adopt the eighties in last century has realized suitability for industrialized production, and has been used widely in industries such as automobile, shipbuilding, wind-power electricity generations.
Domestic at present solid lubrication technology to be applied to the nut field at the early-stage, and the processing and the use of short run have, but big suitability for industrialized production processing is still blank.Minority enterprise is in the process that the processing nut is provided for overseas enterprise; overseas enterprise is for the purpose that reduces cost; require domestic vendors that the solid lubricant coating value-added service is provided when the supply nut simultaneously; but because the extensiveization application of domestic solid lubrication technology on nut also beyond example, causes nut supplier's outlet to be had a strong impact on.
Through market demonstration, my technician of company under the arduous effort of process, has successfully developed nut special solid slip coating, uses the test of producer through state's exterior nut cap, and performance index meet American-European standard fully.This has not only solved the demand of domestic vendors to outlet, and is China's demand to high-end nut in the process of industrial upgrading, and tachnical storage is provided.Expectation is along with the continuous upgrading of CHINESE INDUSTRIES, will be hugely to the demand of high-end nut, and market outlook can be very wide.
[summary of the invention]
At the problems referred to above that nut exists in real use, make a kind of can the realization and hang down between the torque coefficient 0.1-0.13 the nut between the high torque coefficient 0.14-0.17 with solid lubrication coat:
Its coating of making the solid lubricant of nut thread surface is made up of the tetrafluoroethylene of the molybdenumdisulphide that accounts for gross weight 2-12%, 3-6%, the graphite of 1-7%, the Graphene of 0-3%, the tungsten disulfide of 12-18%, the fluorographite of 8-12%, the Resins, epoxy of 16-34%, the nitro-resin of 18-29% and the paint additive of 3-9%.
Apply above-mentioned solid lubricating coating on the nut, it is characterized in that described solid lubrication coat build is 15 ~ 30 microns.
The present invention comprises that also a kind of nut applies the method for above-mentioned solid lubrication coat, adopts above-mentioned solid lubricating coating, is made up of following steps:
The first step adopts the neutral grease-removing agent of normal temperature, to nut in mechanical processing process each quasi-grease and little rubbish of dust, oil stain etc. remove completely, and water cleans.After the washing, dry up workpiece surface with the high pressure gas of high voltage oil-free;
Second step, dilute described solid lubricating coating with solvent or diluent, dilution ratio is 1:0.1-1:0.5, then, the method for spraying or dip-coating solid lubricating coating; Even to obtain coating, the solid lubricant coating of consistency of thickness;
In the 3rd step, to nut solid lubricant coating high temperature sintering, sintering temperature is controlled at 150-230 ℃.
Nut of the present invention can solve the self-lubricating under no oil condition, anti-loosening and anti-interlock problem.Realized between the low torque coefficient 0.1-0.13, between the high torque coefficient 0.14-0.17.Satisfy industries such as automobile, shipbuilding, wind-power electricity generation to the harsh requirement in nut ground, improved equipment reliability of operation and maintenance ground conveniency simultaneously.
The nut solid lubricating coating is to be carrier by macromolecule resin, soft component composite solid lubricant material is added, to obtain good self-lubricating operating performance, as conformability and as far as possible little stinging and being inclined to.Adopt the stack advantage of composite high-molecular resin, composite solid lubricant agent two species complexs, design the high-performance composite solid lubricant coating under the industry special operation condition conditions such as suitable automobile, shipbuilding, wind-power electricity generation, the performance requriements when reaching the nut use.

[embodiment]
In order to make purpose of the present invention, technical scheme and advantage clearer, the present invention is further elaborated.Specific embodiment described herein is only in order to explaining the present invention, and is not used in qualification the present invention.
Embodiment
The prescription of solid lubricating coating is as follows:
Solid lubricant: molybdenumdisulphide 10%, tetrafluoroethylene 3%, graphite 5%, Graphene 1%, tungsten disulfide 16%, fluorographite 10%;
Caking agent: Resins, epoxy 30%, nitro-resin 19%;
Additive: surface treatment agent for powder 6%;
In solid lubricant, add active additive, activation treatment is carried out on the solid lubricant surface, it is combined with macromolecular material better.
Mixing back proportion is 1100 ± 60 grams per liters, is black, and flash-point is 100 ℃.
The concrete steps of the described solid lubricant coating of coating are as follows on nut:
