Abstract
The present invention relates to preparation process of antifriction and anti-fouling solid lubricant, and is especially preparation process of lubricant with graphite as main material and suitable for use in metallurgy, mine, mechanical industry, chemical industry, vehicle, ship, etc. The preparation process includes the following steps: 1. mixing expandable graphite in 40-80 wt% and scale graphite in 20-60 wt%, pressurizing the mixture in some container for 30-60 min and opening the valve to the container for puffing; 2. crushing the puffed mixture to fineness of 3-100 microns; and 3. making the crushed mixture pass through 10-20 magnetic fields of 14-19 kilogauss to obtain the solid lubricant.
Description
Technical field
The present invention relates to the preparation method of a kind of anti-attrition, antifouling solid lubricant.Especially a kind of is the preparation method of the lubricant of raw material with graphite, is applicable to oiling systems such as metallurgy, mine, machinery, chemical industry, vehicle, boats and ships.
Background technology
In recent years, progress along with science and technology, the continual renovation of mechanical means is regenerated, environmental protection, problem such as energy-conservation receive much concern, gear oil, engine wet goods lubricating oil are had higher requirement, and it is that the lubricating oil of additive does not carry out desulfurization, the desiliconization hydrochlorate is handled that existing market is sold with graphite, and in use residual sulphur can cause the pollution of environment at last, residual silicate can influence lubricant effect, makes the oil quality instability.
Summary of the invention
The present invention seeks to overcome the deficiencies in the prior art, provide a kind of and reduce friction, the preparation method of the solid lubricant of good antifouling effect, this method is by the high-intensity magnetic field puffing technique of desulfurization, desiliconization hydrochlorate, the proportion that obtains lubricated product reduces, does not precipitate and harden, and has reached the effect of saving oil and reducing environmental pollution.
Purpose of the present invention can reach by following measure:
A kind of preparation method of solid lubricant, this method comprises the steps:
A, be 40～80% expanded graphite with weight percent with weight percent be that 20～60% crystalline flake graphite mixes and is made into material, prepared materials is put into pressurized vessel be forced into 5～15Kg, after static 30～60 minutes, valves of pressure vessel is aimed at escaper open, it is expanded to carry out gas;
B, the mixture with gas after expanded are crushed to fineness: 3～100 microns;
The magnetic field that c, the mixture after will pulverizing are 1.4～1.9 ten thousand Gausses by 10～20 magnetic flux, the frequency of adjusting magnetic field is 50～150 three harmonic waves, reclaims mixture and gets final product.
The invention has the beneficial effects as follows:
The solid lubricant of preparation method's gained of the present invention integrates the advantage of solid and fluent material, form brand-new and complete electronics adsorption film, filling and repairing, fall the resistance anti-attrition, heat radiation scale removal, sealing anti-are let out, bumper and absorbing shock and anti-ly suppress, protection against corrosion, carbon deposit lubricating system not.This anti-attrition, stain control agent and lubricating oil adapted, the new lubricant that obtains, automobile is used rate of economizing gasoline and is reached more than 10%, trepan rate of economizing gasoline on probation reaches 17%, prolong machine oil work-ing life, drain period can prolong one to three times than plain oil, prolongs one times of engine overhaul mileage, also reduces by 8～10 decibels of mechanicalness noises simultaneously.Test through energy utilization monitoring center of the Ministry of Communications, vehicle torsional moment contrast factor Km=1.04, power contrast factor Kp=1.03, the automobile acceleration characteristics improves 13.6%, vehicle exhaust carbon monoxide and hydrocarbon quantity discharged reduce by 58% and 38.3% respectively than like product, reduce by 96.5% and 77.4% than the national standard limit value.
