Abstract
Description
Oblasť technikyTechnical field
Predložený vynález sa týka kompozícií vazelíny na báze močoviny a prevodov obsahujúcich také kompozície.The present invention relates to urea-based petrolatum compositions and gears containing such compositions.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Cena ropy po takzvanom ropnom šoku prudko stúpla a nápady na ušetrenie zdrojov a energie sa sústavne objavovali v každom odvetví odrážajúc jej vplyv'.The price of oil has risen sharply after the so-called oil shock and ideas for saving resources and energy have consistently emerged in each sector, reflecting its impact.
V odvetví motorových vozidiel boli vyvinuté kompaktné a ľahké všeobecné motorové vozidlá a počet vozidiel využívajúcich spoje s konštantnou rýchlosťou (ďalej v skratke len CVJ - constant velocity joints) stúpol. CVJ sa ďalej využíva vo vozidlách s pohonom všetkých štyroch kolies a vo vozidlách so štyrmi kolesami s nezávislým typom zavesenia a dopyt stále rastie. CVJ, ktorým sa hovorí aj univerzálny spoj s konštantou rýchlosťou, je spoj, ktorý prenáša rotáciu so zachovaním konštantnej uhlovej rýchlosti a krútiaceho momentu, a má rôzne typy v závislosti od rôznych využití. Mazadlá používané na CVJ sú vystavené náročnejším podmienkam, keďže motorové vozidlo dosahuje vyšší výkon a vyššiu rýchlosť a CVJ samotné sa stávajú kompaktnými, a preto je potrebná vazelína, ktorá znižuje trenie a opotrebovanie klzných častí. Okrem toho je potrebný tesniaci prvok, ktorý bráni presakovaniu vazelíny a vnikaniu cudzích predmetov a vody zvonka. Ako materiál sa väčšinou používa chloroprénový kaučuk a polyesterové živice.Compact and lightweight general motor vehicles have been developed in the motor vehicle industry and the number of vehicles using constant speed links (CVS - constant velocity joints) has increased. CVJ is also used in all-wheel-drive vehicles and in four-wheel-drive vehicles with independent suspension type, and demand continues to grow. A CVJ, also called a universal constant speed joint, is a joint that transmits rotation while maintaining constant angular velocity and torque, and has different types depending on different applications. Lubricants used on CVJs are exposed to more demanding conditions as the motor vehicle achieves higher power and higher speed and the CVJs themselves become compact, and therefore grease is required to reduce friction and wear of sliding parts. In addition, a sealing element is required to prevent grease leakage and foreign objects and water from entering the outside. Chloroprene rubber and polyester resins are generally used as the material.
Vazelína, ktorá je vynikajúca v znižovaní trenia a zvyšovaní odolnosti proti opotrebovaniu, potláča vibrácie a hluk karosérie vozidla počas štartovania a zrýchľovania a počas jazdy. Navyše vďaka účinku znižovania teploty možno zvýšiť trvanlivosť tesniaceho prvku. Nadmerné zvyšovanie teploty však zvyšuje starnutie tesniaceho prvku a degradácia mazadla výrazne skracuje životnosť CVJ.Grease, which is excellent in reducing friction and increasing wear resistance, suppresses the vibration and noise of the vehicle body during starting and acceleration and while driving. Moreover, the durability of the sealing element can be increased due to the lowering effect. However, excessive temperature increase increases the aging of the sealing element and degradation of the lubricant significantly shortens the life of the CVJ.
Na druhej strane v oceliarskom priemysle sa ďalej rozvinula kontinuálna prevádzka mechanických zariadení. S technickou revolúciou došlo k výraznému dopytu po vysokej kvalite produktu, zlepšovaní v kapacite výrobného procesu, zabezpečení spoľahlivosti prístrojov a podobne. Podmienky mazania sú veľmi náročné, keďže vazelíny používané v týchto mechanických prístrojoch sú v ťažkom prostredí, teda vo vysokej teplote, v styku s vodou, s vysokou možnosťou prieniku cudzích látok, ako je napríklad vodný kameň a podobne, a sú týmto náročným podmienkam vystavené dvadsaťštyri hodín denne. Je potrebná vazelína, ktorá má vynikajúcu tesniacu odolnosť a ktorá znižuje trenie a opotrebovanie, aby predĺžila životnosť mechanických častí a zabránila náhlemu zlyhaniu zariadenia. Ďalej súčiastky, ktoré treba mazať v strojárskom priemysle, zahŕňajú obrábacie stroje a podobne, ktoré trpia značným trením, a nadmerné opotrebovanie spôsobuje znižovanie presnosti stroja, takže mechanické časti sa musia vymieňať. Ako je opísané, zníženie trenia a opotrebovania je dôležitým cieľom predloženého vynálezu.On the other hand, the continuous operation of mechanical equipment has further developed in the steel industry. With the technical revolution, there has been a strong demand for high product quality, improvements in production process capacity, ensuring instrument reliability, and the like. Lubrication conditions are very demanding as the greases used in these mechanical devices are in difficult environments, i.e. at high temperature, in contact with water, with a high potential for foreign substances such as lime scale and the like to be exposed to twenty-four. hours a day. Grease is required which has excellent sealing resistance and which reduces friction and wear in order to prolong the life of mechanical parts and prevent sudden failure of the device. Furthermore, the components to be lubricated in the mechanical engineering industry include machine tools and the like that suffer from considerable friction, and excessive wear causes a reduction in the accuracy of the machine, so that mechanical parts must be replaced. As described, reducing friction and wear is an important object of the present invention.
Pri opísaných súčiastkach, ktoré vyžadujú mazanie, sa preto výhodne využívali vazelíny na báze lítia s využitím zlúčenín na báze síry, napríklad sírený tuk a olej, sírené olefíny a podobne, naftenát olovnatý, kovové ditiofosfáty, aditíva na báze kovových ditiokarbamátov a podobne. Nedávno sa začali vo zvýšenej miere používať vazelíny na báze lítiového komplexu a močovinové vazelíny, ktoré sú lepšie v tepelnej odolnosti oproti vazelínam na báze lítia.Lithium based greases using sulfur-based compounds, such as sulfur fat and oil, sulfur olefins and the like, lead naphthenate, metal dithiophosphates, metal dithiocarbamate additives, and the like, have therefore been advantageously used in the described components requiring lubrication. More recently, lithium complex greases and urea greases, which are better in heat resistance than lithium greases, have been increasingly used.
Ako predstaviteľ doterajšieho stavu techniky uvádza americký patent č. 4 514 312 vazelínu využívajúcu aromatický aminfosfát ako organickú prísadu neobsahujúcu žiadnu síru v močovinovej vazelíne. Ďalej americký patent č. 4,840,740 uvádza vazelínu obsahujúcu močovinovú vazelínu, organickú zlúčeninu molybdénu a ditiofosfát zinočnatý. Japonská patentová publikácia (JP-B) č. 04-34590 (1992) uvádza močovinovú vazelínu obsahujúcu ako podstatnú zložku vysokotlakovú prísadu na báze síry a fosforu pozostávajúcu z nasledujúcich zložiek:As representative of the prior art, U.S. Pat. No. 4,514,312 petrolatum utilizing aromatic amine phosphate as an organic additive containing no sulfur in urea petrolatum. Further, U.S. Pat. No. 4,840,740 discloses petrolatum comprising urea petrolatum, an organic molybdenum compound and zinc dithiophosphate. Japanese Patent Publication (JP-B) no. No. 04-34590 (1992) discloses urea petrolatum containing, as an essential component, a high pressure additive based on sulfur and phosphorus consisting of the following components:
1. dialkylditiokarbamát sulfid molybdénu a1. Molybdenum sulfide dialkyldithiocarbamate a
2. jednu alebo kombináciu dvoch alebo viacerých zložiek vybraných zo skupiny pozostávajúcej zo síreného tuku a oleja, síreného olefínu, trikrezylfosfátu, trialkyltiofosfátu a dialkylditiofosfátu zinočnatého.2. one or a combination of two or more components selected from the group consisting of sulphurized fat and oil, sulphurized olefin, tricresyl phosphate, trialkylthiophosphate and zinc dialkyldithiophosphate.
Hoci sa uznáva, že niektoré vazelíny podľa doterajšieho stavu techniky majú účinky znižovania trenia a opotrebovania, plná spokojnosť sa nedosiahla. Okrem toho je nevýhodou, že tesniace prostriedky sa za vysokej teploty znehodnocujú. Napríklad aromatický aminfosfát a naftenát olovnatý degradujú polyesterové živice a sírený tuk a olej degraduje chloroprénový kaučuk a sírený olefin výrazne degraduje chloroprénový kaučuk aj polyesterové živice.Although it is recognized that some of the prior art greases have the effects of reducing friction and wear, full satisfaction has not been achieved. Moreover, it is a disadvantage that the sealants deteriorate at high temperature. For example, the aromatic amine phosphate and lead naphthenate degrade polyester resins and the sulfurized fat and oil degrades chloroprene rubber and the sulfurized olefin significantly degrades chloroprene rubber and polyester resins.
Okrem toho japonská patentová prihláška (JP-A) Č. 08-157859 (1996) uvádza použitie dialkylditiokarbamát sulfidu molybdénu a trifenylfosfortionátu ako prísad a japonská patentová prihláška (JP-A) č. 62-2275197 (1987) uvádza použitie lítiového mydla 12-hydroxy mastnej kyseliny, lítneho fosfátu vytvoreného z fosfátu, ako je napríklad trimetylfosfát alebo trifenylfosfát, ako zahusťovadiel. Ďalej japonská patentová prihláška (JP-A) č. 03-231993 (1991) uvádza vazelínovú kompozíciu využívajúcu fosfátový olej v močovinovej zlúčenine.In addition, Japanese Patent Application (JP-A) no. No. 08-157859 (1996) discloses the use of molybdenum sulfide dialkyldithiocarbamate and triphenylphosphoricionate as an additive, and Japanese Patent Application (JP-A) No. 08/7859. 62-2275197 (1987) discloses the use of 12-hydroxy fatty acid lithium soap, a lithium phosphate formed from a phosphate such as trimethyl phosphate or triphenyl phosphate, as a thickening agent. Further, Japanese Patent Application (JP-A) no. 03-231993 (1991) discloses a petrolatum composition utilizing a phosphate oil in a urea compound.
Podstata vynálezuSUMMARY OF THE INVENTION
Predložený vynález sa týka močovinovej vazelíny, ktorá je vynikajúca vo vlastnostiach trenia a odolnosti proti opotrebovaniu a má tiež dobrú kompatibilitu s tesniacim prostriedkom, ako je napríklad chloroprénový kaučuk a polyesterová živica. Predložený vynález sa konkrétne týka kompozície močovinovej vazelíny vhodnej na aplikáciu na také časti, ktoré sa majú mazať vazelínou, ako sú spoje s konštantnou rýchlosťou, guľové spoje a guľkové ložiská v motorových vozidlách a ložiská a prevody rôznych priemyselných zariadení, ako sú napríklad oceliarske a priemyselné stroje a obrábacie stroje.The present invention relates to urea petrolatum which is excellent in friction and wear resistance properties and also has good compatibility with a sealant such as chloroprene rubber and polyester resin. In particular, the present invention relates to a urea grease composition suitable for application to parts to be greased with petroleum jelly, such as constant speed joints, ball joints and ball bearings in motor vehicles and bearings and gears of various industrial equipment such as steel and industrial machines and machine tools.
Predložený vynález sa týka kompozície močovinovej vazelíny obsahujúcej močovinovú vazelínu a ako prísady (A) dialkylditiokarbamát sulfid molybdénu, ktorý predstavuje vzorec:The present invention relates to a urea petrolatum composition comprising urea petrolatum and as additive (A) a dialkyl di-dithiocarbamate molybdenum sulfide, which is represented by the formula:
N C S- Μθ2θ|γ|δη ; kde R1 a R2 každé nezávisle predstavujú skupinu vybranú zo skupiny pozostávajúcej z alkylových skupín s 1 až 24 atómami uhlíka; m je 0 alebo celé číslo od 1 do 3; a n je celé číslo od 1 do 4; s tým, že súčet m a n je 4 a (B) trifenylfosfát, ktorý predstavuje vzorec:NC S- 2θ2θ | γ | δη ; wherein R 1 and R 2 each independently represent a group selected from the group consisting of alkyl groups of 1 to 24 carbon atoms; m is 0 or an integer from 1 to 3; and n is an integer from 1 to 4; provided that the sum of m and n is 4 and (B) triphenylphosphate, which is represented by the formula:
Zlúčeniny zodpovedajúce uvedenej zložke (A) majú vysokú teplotu topenia. Medzi príklady na takéto zlúčeniny patrí dietylsulfid-ditiokarbamát molybdénu, dibutyl-ditiokarbamát molybdénu, diizobutylsulfidditiokarbamát molybdénu, di(2-etylhexyl)sulfid-ditiokarbamát molybdénu, diamylsulfid-ditiokarbamát molybdénu, diizoamylsulfid-ditiokarbamát molybdénu, dilaurylsulfid-ditiokarbamát molybdénu, distearylsulfidditiokarbamát molybdénu. Výhodne sa primiešavajú vo forme prášku a pridávané množstvo sa pohybuje od 0,5 do 10 % hmotnostných, výhodne od 0,5 do 5 % hmotnostných vzhľadom na celkovú hmotnosť. Keď je pridané množstvo menšie ako 0,5 % hmotnostného, účinok zlepšenia v trecej odolnosti a odolnosti proti opotrebovaniu je všeobecne nedostatočný a keď sa pridá viac ako 10 % hmotnostných, väčšinou sa už nedosiahne žiadne ďalšie zlepšenie.The compounds corresponding to component (A) above have a high melting point. Examples of such compounds include dietylsulfid-molybdenum dithiocarbamate, dibutyl-molybdenum dithiocarbamate, molybdenum diizobutylsulfidditiokarbamát, di (2-ethylhexyl) sulfide-molybdenum dithiocarbamate, diamyl sulfide-molybdenum dithiocarbamate, diisoamyl sulfide-molybdenum dithiocarbamate, dilauryl sulfide-molybdenum dithiocarbamate, molybdenum distearylsulfidditiokarbamát. They are preferably admixed in powder form and the amount added is from 0.5 to 10% by weight, preferably from 0.5 to 5% by weight, based on the total weight. When the amount added is less than 0.5% by weight, the effect of the improvement in frictional and wear resistance is generally insufficient, and when more than 10% by weight is added, in most cases no further improvement is achieved.
Keďže trifenylfosfát má teplotu topenia 50 °C a je pri teplote miestnosti tuhý, je výhodné, keď sa prášok mieša so základnou vazelínou pri teplote najmenej 50 CC. Množstvo zložky (B) je výhodne od 0,1 do 10 % hmotnostných, výhodnejšie od 0,1 do 5 % hmotnostných vzhľadom na celkovú hmotnosť. Keď sa použije menej ako 0,1 % hmotnostného, väčšinou nemožno dosiahnuť zlepšenie v trecej odolnosti a odolnosti proti opotrebovaniu a keď sa použije viac ako 10 % hmotnostných, už väčšinou nemožno získať vyššiu mazaciu schopnosť.Since triphenylphosphate has a melting point of 50 ° C and is solid at room temperature, it is preferred that the powder is mixed with a basic petrolatum at a temperature of at least 50 ° C. The amount of component (B) is preferably from 0.1 to 10% by weight, 0.1 to 5% by weight based on the total weight. When less than 0.1% by weight is used, it is generally not possible to achieve an improvement in friction and wear resistance, and when more than 10% by weight is used, it is usually not possible to obtain a higher lubricity.
Čo sa týka močovinovej zlúčeniny, možno použiť akékoľvek známe zahusťovadlo močovinového typu. Možno napríklad použiť dimočovinu, trimočovinu a tetramočovinu.For the urea compound, any known urea-type thickener can be used. For example, dimurea, trimurea and tetramurea may be used.
Ako základný olej možno použiť minerálny olej a/alebo syntetický olej. Ak sa ako zahusťovadlo použije zlúčenina močoviny, výhodne sa aplikuje v množstve od 2 do 35 % hmotnostných vzhľadom na celkovú hmotnosť základného oleja a zlúčeniny močoviny.Mineral oil and / or synthetic oil may be used as the base oil. When a urea compound is used as a thickening agent, it is preferably applied in an amount of from 2 to 35% by weight based on the total weight of the base oil and the urea compound.
Do kompozície podľa predloženého vynálezu možno pridať aj rôzne prísady, ako napríklad antioxidanty, protikorózne činidlá, vysokotlakové činidlo, polyméry a podobne.Various additives such as antioxidants, anticorrosive agents, high pressure reagent, polymers and the like can also be added to the composition of the present invention.
Kompozície močovinovej vazelíny podľa vynálezu sú osobitne vhodné na použitie v prevodoch, špecifickejšie v spojoch s konštantnou rýchlosťou. Predložený vynález sa teda ďalej týka prevodov, špecifickejšie spojov s konštantnou rýchlosťou, obsahujúcich takú vazelínu.The urea petrolatum compositions of the invention are particularly suitable for use in gears, more specifically in constant speed joints. Thus, the present invention further relates to gears, more particularly to constant speed joints containing such petrolatum.
Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Predložený vynález bude špecificky opísaný na základe príkladov a porovnávacích príkladov, nemá sa však chápať ako obmedzený na uvedené príklady. Prísady sa pridávali do základných vazelín v miešacích pomeroch podľa tabuliek 1 až 5 (všetky sú uvedené v hmotnostných percentách). Zmesi sa spracovali v trojvalcových mlynoch, čím sa získali vazelíny podľa príkladov a porovnávacích príkladov.The present invention will be specifically described by way of examples and comparative examples, but is not to be construed as limited to the examples given. Additives were added to the baseline grease at mixing ratios according to Tables 1 to 5 (all percentages by weight). The mixtures were processed in triple-roll mills to give petrolatum according to the Examples and Comparative Examples.
Formulácie vazelín sú opísané neskôr. Ako základný olej sa použil čistený minerálny olej s viskozitou 15 mm2/s pri 100 °C.Vaseline formulations are described later. Purified mineral oil having a viscosity of 15 mm 2 / s at 100 ° C was used as the base oil.
I. Vazelína na báze dimočovinyI. Vaseline based on dimurea
Jeden mól difenylmetán-4,4’-diizokyanátu a 2 móly oktylaminu zreagovali v základnom oleji a získaná močovinová zlúčenina sa rovnomerne dispergovala, čím sa získala vazelína. Množstvo zlúčeniny močoviny bolo 10 % hmotnostných vzhľadom na celkovú hmotnosť základného oleja a močovinovej zlúčeniny.One mole of diphenylmethane-4,4'-diisocyanate and 2 moles of octylamine were reacted in the base oil, and the obtained urea compound was dispersed evenly to give petrolatum. The amount of urea compound was 10% by weight based on the total weight of the base oil and the urea compound.
Vazelína na báze tetramočovinyVaseline based on tetramurea
Dva móly difenylmetán-4,4’-diizokyanátu, 2 móly oktylaminu a 1 mól etyléndiamínu zreagovali v základnom oleji a získaná zlúčenina močoviny sa rovnomerne dispergovala, čím sa získala vazelína. Množstvo zlúčeniny močoviny bolo 15 % hmotnostných vzhľadom na celkovú hmotnosť základného oleja a močovinovej zlúčeniny.Two moles of diphenylmethane-4,4'-diisocyanate, 2 moles of octylamine and 1 mole of ethylenediamine were reacted in the base oil and the urea compound obtained was dispersed evenly to give petrolatum. The amount of urea compound was 15% by weight based on the total weight of the base oil and the urea compound.
Vazelína na báze lítiového komplexuVaseline based on lithium complex
Hydrogenovaná mastná kyselina z bobrieho oleja sa rozpustila v základnom oleji, do ktorého sa pridal vodný roztok hydroxidu lítneho na neutralizáciu a zmes sa počas reakcie dehydrovala. Po skončení dehydratácie sa pridala kyselina azealová. Reakcia sa uskutočnila pomocou vodného roztoku hydroxidu litneho v množstve potrebnom na neutralizáciu. Azealát lítny a 12-hydroxystearát lítny sa zmiešali a rovnomerne dispergovali, čím sa získala vazelína. Množstvo 12-hydroxystearátu ako zahusťovadla bolo 7,5 % hmotnostných a množstvo azealátu lítneho bolo 2,5 % hmotnostných vzhľadom na celkovú hmotnosť základného oleja a zahusťovadla.The hydrogenated beaver oil fatty acid was dissolved in the base oil to which aqueous lithium hydroxide solution was added to neutralize and the mixture was dehydrated during the reaction. After dehydration, azealic acid was added. The reaction was carried out with an aqueous solution of lithium hydroxide in an amount necessary for neutralization. Lithium azealate and lithium 12-hydroxystearate were mixed and uniformly dispersed to give petrolatum. The amount of 12-hydroxystearate as a thickener was 7.5% by weight and the amount of lithium azealate was 2.5% by weight based on the total weight of the base oil and thickener.

Tabuľka 6Table 6
Koeficienty trenia v príkladoch 1 až 7 sú všetky menšie v porovnaní s koeficientmi z porovnávacích príkladov 1 až 10. Co sa týka odolnosti proti vode, porovnávacie príklady 5, 6, 7, 9 a 10 poskytujú rovnaký stupeň dobrých výsledkov ako príklady podľa vynálezu. Tieto porovnávacie príklady sú však horšie v kompatibilite s chloroprénovým kaučukom a/alebo polyesterovou živicou.The friction coefficients in Examples 1 to 7 are all smaller than those of Comparative Examples 1 to 10. With respect to water resistance, Comparative Examples 5, 6, 7, 9 and 10 provide the same degree of good results as the Examples of the invention. However, these comparative examples are worse in compatibility with chloroprene rubber and / or polyester resin.
Napríklad porovnávací príklad 5 dáva veľkú zmenu v predĺžení chloroprénového kaučuku a polyesterovej živice. Porovnávací príklad 6 dáva veľkú zmenu v pevnosti v ťahu a v predĺžení chloroprénového kaučuku a polyesterovej živice. Porovnávacie príklady 9 a 10 dávajú pomerne veľkú zmenu v predĺžení polyesterovej živice. Príklady 1 až 7 dávajú vynikajúci koeficient trenia a odolnosť proti opotrebovaniu a tiež vynikajúcu kompatibilitu s tesniacim prostriedkom z chloroprénového kaučuku a polyesterovej živice.For example, Comparative Example 5 gives a major change in the elongation of chloroprene rubber and polyester resin. Comparative Example 6 gives a great change in tensile strength and elongation of chloroprene rubber and polyester resin. Comparative Examples 9 and 10 give a relatively large change in the elongation of the polyester resin. Examples 1 to 7 give an excellent coefficient of friction and wear resistance, as well as excellent compatibility with the sealant of chloroprene rubber and polyester resin.
Vazelína podľa predloženého vynálezu má nízky koeficient trenia a je vynikajúca v odolnosti proti opotrebovaniu. V dôsledku toho sa znižujú vibrácie a hluk CVJ motorových vozidiel. Okrem toho vazelína podľa predloženého vynálezu znižuje trenie v guľových spojoch a ložiskách kolies motorových vozidiel a iných rôznych priemyselných strojov a môže predĺžiť životnosť strojových súčastí.The petrolatum of the present invention has a low coefficient of friction and is excellent in wear resistance. As a result, the vibration and noise of CVJ motor vehicles are reduced. In addition, the grease of the present invention reduces friction in ball joints and wheel bearings of motor vehicles and other various industrial machines and can extend the life of machine components.
Vazelína podľa predloženého vynálezu je vynikajúca vo vlastnosti kompatibility s chloroprénovým kaučukom a polyesterovou živicou a spomaľuje degradáciu tesniaceho prostriedku prístroja dokonca aj pri vysokých teplotách.The petrolatum of the present invention is excellent in the property of compatibility with chloroprene rubber and polyester resin and slows down the degradation of the device sealant even at high temperatures.
