Abstract
Prezenta invenție se referă la o compoziție polimerică, de etanșare, pentru realizarea etanșărilor la sistemele care lucrează, sub vid sau sub presiune de apă, abur, hidrogen și are la bază cauciuc butadien acrilonitrilic. Utilizând compoziția conform invenției se obțin paste de etanșare polimerice autovulcanizabile, aderente la suprafața planurilor de separație ale reductoarelor motoarelor electrice, ale pompelor de păcură, ale pompelor de vid și ventilatoarelor de aer.The present invention relates to o polymeric, sealant composition for making seals to work in vacuum systems or under pressure of water, steam, hydrogen and has at butadiene acrylonitrile rubber base. using the composition according to the invention obtains pastes of self - vulcanizable polymer sealing, adherent to the area of the gearbox separation plan electric motors, fuel oil pumps, vacuum pumps and air fans.
Description
Invenția se referă la o compoziție polimerică de etanșare utilizată pentru etanșări la sistemele care lucrează sub vid sau sub presiune de apă, abur, hidrogen, etc.The invention relates to a polymeric sealing composition used for seals in systems working under vacuum or under pressure of water, steam, hydrogen, etc.
Etanșările la presiune ridicată se 5 realizează cu ajutorul garniturilor elastice din cauciuc, dar sunt dependente de calitatea cauciucului, execuția garniturii, cât și de îmbătrânirea elastomerului în contact cu mediul de lucru. ioHigh pressure seals are made with the help of elastic rubber gaskets, but they are dependent on the quality of the rubber, the execution of the gasket, as well as the aging of the elastomer in contact with the working environment. io
Etanșările pentru sisteme sub vid sunt destinate împiedicării pătrunderii aerului din mediul ambiant, fenomen ce depinde de mărimea coeficientului de permeabilitate la aer a materialelor utilizate. In plus, la un vid 15 înaintat, garniturile de cauciuc prezintă pericolul dislocării dintre planurile de separație ca urmare a unei strângeri neuniforme.Seals for vacuum systems are intended to prevent air from entering the environment, a phenomenon that depends on the size of the air permeability coefficient of the materials used. In addition, at a high vacuum 15, the rubber seals present the danger of dislocation between the separation planes due to an uneven tightening.
In scopul eliminării inconvenientelor sus-menționate, se folosesc materiale de 2 o etanșare fluide vâscoase care umplu perfect spațiul de etanșare.In order to eliminate the aforementioned disadvantages, 2 viscous fluid sealing materials are used which fill the sealing space perfectly.
Sunt cunoscute compoziții pentru astfel de etanșări, unele nevulcanizabile în timp, iar cele autovulcanizabile au coeficient relativ 2 5 mare de penetrabilitate la gaze și stabilitate redusă la condițiile de mediu de lucru și temperatură, necesitând materii prime neaccesibile pentru fabricație.Compositions are known for such seals, some that are not vulcanizable over time, and the self-vulcanizable ones have a relatively high coefficient of gas penetration and reduced stability under working conditions and temperature, requiring raw materials not accessible for manufacturing.
Compoziția, conform invenției, 3 0 înlătură dezavantajele amintite prin faptul că este constituită din: 100 părți de cauciuc butadien - acrilonitrilic șarjat cu 5 părți oxid de zinc, 3 părți rezorcină, 5 părți rășină cumaron - indenică, 15 părți caolin, 3 părți tetrametiltiuramdisulfură sau N - ciclohexilbenztriazil - 2 sulfenamidă și 3 părți sulf, părțile fiind în greutate.The composition, according to the invention, removes the disadvantages mentioned by the fact that it consists of: 100 parts butadiene rubber - acrylonitrile loaded with 5 parts zinc oxide, 3 parts resorcine, 5 parts coumarin - indenic resin, 15 parts kaolin, 3 parts tetramethylthiurisurdis. or N - cyclohexylbenztriazil - 2 sulfenamide and 3 parts sulfur, the parts being by weight.
Invenția se referă la un material polimeric aderent la metal și autovulcanizabil în timp, rezistent la apă, abur, hidrogen, uleiuri minerale și agenți chimici, care poate fi utilizat la planurile de separație de la reductoarele motoarelor electrice de antrenare, la pompe de păcură din stațiile dozatoare de combustibil, pompe de vid, ventilatoare de aer etc.The invention relates to a polymer material adherent to metal and self-vulcanizable over time, resistant to water, steam, hydrogen, mineral oils and chemical agents, which can be used in separation plans from reducers of electric drive motors, to fuel pumps from fuel dispensing stations, vacuum pumps, air fans, etc.
Compoziția, conform invenției, prezintă o serie de avantaje:The composition, according to the invention, has a number of advantages:
- caracteristici fizico-mecanice și de stabilitate la condițiile mediului de lucru superioare;- physical-mechanical characteristics and stability at higher working conditions;
- materii prime si materiale de fabricație ușor accesibile;- easily accessible raw materials and manufacturing materials;
- siguranță în funcționarea utilajelor;- safety in machine operation;
- eliminarea perioadelor de staționare a instalațiilor ca urmare a necesității refacerii etanșărilor.- elimination of the periods of stationary installation due to the need to restore the seals.
In continuare, se prezintă două exemple de realizare a invenției, componenții, proporțiile de asociere și parametrii de lucru fiind redate în tabelul 1.In the following, two examples of embodiment of the invention are presented, the components, the association ratios and the working parameters being shown in table 1.
