Abstract
The invention discloses a high-speed type friction-reducing agent and a preparation method thereof. The high-speed type friction-reducing agent comprises the following raw materials by the mass percentage: 80% of poly alpha olefin, 12% of lithium hydroxide, 1% of sulfurized isobutene, 0.5% of phosphate ester, 0.3% of 2,6-di-tert-butyl-p-cresol, 3% of polyisobutylene, 0.5% of alkenyl succinic acid ester, 0.35% of alkyl naphthalene, 2% of sebacic acid and 0.35% of sulfonated oil DIH. The preparation method comprises the following specific steps: putting other raw materials except poly alpha olefin into a contact container, adding water, and heating up and carrying out saponification; after saponification, adding water for washing, putting into a reaction kettle, adding a part of poly alpha olefin, separating water, and discharging water; increasing the pressure of the reaction kettle to 0.8 MPa, at the same time, heating up, when the temperature reaches 160-170 DEG C, adding the rest of poly alpha olefin, and thickening into grease; changing the kettle and cooling; and grinding, and degassing to obtain the finished product. The high-speed type friction-reducing agent has the beneficial effects that: wear between a steel rail and a wheel rim is reduced, thereby reducing depreciation; and the locomotive running friction is reduced, thereby saving energy and reducing emission.
Description
Technical field
The present invention relates to anti-friction composition field, is mainly a kind of high-speed type anti-friction composition and preparation method.
Background technology
Since entering 21 century, along with the develop rapidly of China's economic and the quickening of urbanization process, urban track traffic also enters great development period.By the end of the year 2012, the whole nation has 28 cities to continue to build rail line engineering altogether, continues circuit and amounts to 63 sections, 1399 kilometers of mileages, 970, station.China's speed per hour reaches 200 kilometers of above high-speed railway mileages and has approached 13000 kilometers.Operation mileage, operation speed per hour, building scale, tempo, all occupy the first in the world.
Along with the development of urban track traffic, because subway line is subject to the impact of City Building, subway line curve is more, and radius of curve is less, and rail of subway and railcar wheel wear phenomenon are generally very serious.
Current, national each large-and-medium size cities are comprehensive newly-built urban track traffic, and all track traffics all will face the situation of wheel wear and rail abrasion.So railway anti-friction composition has boundless market outlook.2010, the Ministry of Railways formulated the lubricated > > standard of industry standard TB/T3223.1-2010 < < wheel rim of locomotive, and railway anti-friction composition has been formulated to technological standard and requirement.
Railway anti-friction composition is not used on a large scale in China at present, and optional product only has external imported product and domestic 1-2 kind lubricating grease surrogate (the not railway anti-friction composition of stricti jurise).The production of railway anti-friction composition product is at home in space state, its present situation is imported product selling at exorbitant prices, and domesticly not having ripe railway anti-friction composition production technology and a production firm, other domestic lubricating grease surrogate production technologies are comparatively backward, are difficult to meet national standard and actual effect.
Railway anti-friction composition is different from general lubricant, because the characteristic of the envrionment conditions of its outdoor use and railway wheel rim high speed rotating requires railway anti-friction composition product to meet following demand:
1, the scope of application: be applicable to the lubricated anti-attrition effect of the rail medial surface of state's iron and subway; Be applicable to the lubricated anti-attrition effect of rolling stock wheel rim under various operation conditions.
2, antifriction effect: rate of wear drop to 1/3rd while originally not using anti-friction composition and more than.
3, anti-friction composition does not have corrodibility to wheel and rail etc.
4, anti-friction composition meets the normal oil spout functional requirement of existing various fueling injection equipments, must not stop up injection tubing.
5, railway anti-friction composition working temperature :-30 ℃---+60 ℃.
6, resistance of rainwater washing against, under the high speed rotating of wheel, have enough sticking power.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of high-speed type anti-friction composition and preparation method are provided, reduce the wearing and tearing of rail and wheel rim, reduce depreciation; Reduce locomotive operation friction, energy-saving and emission-reduction.
The object of the invention is to complete by following technical solution.This high-speed type anti-friction composition, raw material by following mass percent forms: poly-@alkene 80%, lithium hydroxide 12%, sulfide isobutene 1%, phosphoesterase 30 .5%, 2,6 ditertbutylparacresols 0.3%, polyisobutene 3%, alkenyl succinic acid ester 0.5%, alkylnaphthalene 0.35%, sebacic acid 2% and sulphonated oil DIH0.35%.
The preparation method of this high-speed type anti-friction composition, concrete steps are as follows:
The first step, except poly-@alkene, all the other raw materials drop in contactor, add the water of raw materials quality 30%-50%, intensification saponification, control pressure is 0.5-0.6Mpa, temperature is at 95-105 ℃;
Second step, adds the water washing of raw materials quality 300%-500% after saponification, drop into reactor, then adds the poly-@alkene of total amount 20% to divide water, emits water;
The 3rd step, reactor is forced into 0.8Mpa, heats up simultaneously, and heat-up rate is 5～8 ℃/min, and temperature adds surplus to gather@alkene while reaching 160-170 ℃, be crowded into fat;
The 4th step, changes still and is cooled to below 100 ℃;
The 5th step, through grinding, degassed getting product.
The invention has the beneficial effects as follows: the present invention develops with reference to the lubricated > > industry standard of the TB/T3223.1-2010 < < of Ministry of Railways wheel rim of locomotive completely, there is the approaching performance of imported product, with lower production cost, filled up the market vacancy.Now this product is by Hangzhou locomotive depot of Shanghai Railway Bureau service testing, and antifriction effect meets industry standard and practical application request, and reaches imported product level.
