Description
2 CS 267 196 B12 EN 267 196 B1
Vynález sa týká přípravku, ktorý po zriedení s vodou vytvára reznú kvapalinu pre obrába-nie, najma brúsenie ocele a liatiny.BACKGROUND OF THE INVENTION The present invention relates to a composition which, upon dilution with water, produces a cutting fluid for machining, in particular grinding steel and cast iron.
Režná kvapalina pri brúsení má za úlohu v prvom radě odvádzat vzníkajúce teplo.The abrasive fluid in the first row is intended to discharge the igniting heat in the first row.
Najviac používanými režnými kvapalinami sú emulzné režné kvapaliny, ktoré sú založenéprevažne na minerálnych olejoch v kombinácii s emulqátormi. Nevýhodou tohto druhu režnýchkvapalín je vylučovanie oleja z emulzie, čo má za následok zníženie protikorozívnej ochranya nizku odolnost voči bakteriálnemu rozkladu.The most commonly used coarse liquids are emulsion coarse liquids which are mainly based on mineral oils in combination with emulsifiers. A disadvantage of this kind of plain capillary is the excretion of oil from the emulsion, which results in a reduction of the anticorrosive protection and low resistance to bacterial decomposition.
Vyššíe uvedené nedostatky odstraňuje prípravok pre obrábanie, najmS brúsenie ocelea liatiny s vysokou chladiacou účinnosíou, s minimálnou penivostou a s dobrými antikoróznymivlastnosťami vyznačujúci sa tým, že ako mazacie látky obsahuje 5 až 25 S hmot. polyetylén-glykolu molekulovej hmotnosti 300 až 1 500, ako inhibitor korózie obsahuje 3 až 25 % hmot.produktu připraveného zmiešaním 95 % hmot. trietanolamínu s 5 % hmot. kyseliny citrónovejpri teplote 50 až 150 °C po dobu 15 až 120 minút, ako látky zamedzujúce mikrobiálnemu roz-kladu obsahuje až 2 % hmot. formaldehydu alebo zmesi synergicky pósobiacich hexahydrotriazin-derivátov a N-oxymetylaminoderivátov, alebo zmesi formaldehydu so zmesou synergicky pósobiacichhexahydrotriazínderivátov a N-oxymetylaminoderivátov a do 100 % hmot. tvoři voda.The above-mentioned drawbacks are eliminated by the machining tool, in particular by grinding steel and cast iron with high cooling efficiency, with minimal foaming and good anticorrosive properties, characterized in that it contains 5 to 25% by weight as lubricant. polyethylene glycol having a molecular weight of from 300 to 1500, as a corrosion inhibitor, contains from 3 to 25% by weight of the product prepared by mixing 95% by weight of polyethylene glycol; % triethanolamine with 5 wt. citric acid at a temperature of 50 to 150 ° C for 15 to 120 minutes, containing up to 2% by weight of microbial decomposition; of formaldehyde or a mixture of synergistically acting hexahydrotriazine derivatives and N-oxymethylamine derivatives, or a mixture of formaldehyde with a mixture of synergistically acting hexahydrotriazine derivatives and N-oxymethylamine derivatives and up to 100% by weight. they form water.
Prípravok podlá vynálezu má tieto výhody: - jednoduchá příprava reznej kvapaliny zriedením přípravku vodou 1:10 až 1:100 - vysoká chladiaca účinnost - minimálna penivosť aj v mákkej vodě. Příklad 1The composition according to the invention has the following advantages: - simple preparation of the cutting fluid by diluting the composition with water 1:10 to 1: 100 - high cooling efficiency - minimal foaming even in soft water.
