Description

Fremgangsmåte ved vulkanisering av syntetisk kautsjuk på basis av klorsulfonert polyetylen og dettes homologe. Procedure for vulcanization of synthetic rubber based on chlorosulfonated polyethylene and its homologues.

Som kjent kan naturkautsjuk og syn-tetiske kautsjukarter vulkaniseres. Til vulkanisering av naturkautsjuk anvendes i As is known, natural rubber and synthetic rubber types can be vulcanized. For vulcanization of natural rubber i

uten svovel, ved tilsetning av bestemte kje-mikalier, som f. eks. metalloksyder eller or-ganiske forbindelser. Denne siste fremgangsmåte er særlig blitt anvendt ved vulkanisering av syntetisk kautsjuk. Særlig without sulphur, by adding specific chemicals, such as e.g. metal oxides or organic compounds. This last method has been particularly used in the vulcanization of synthetic rubber. Especially

ved vulkanisering av polykloroprener er by vulcanization of polychloroprenes is

det kjent å anvende diaminer, monofunk-sjonelle aldehyd-amin-forbindelser o. a., og it is known to use diamines, monofunctional aldehyde-amine compounds, etc., and

har det imidlertid vist seg, at koldvulkani-seringen som oftest foregår for langsomt, however, it has been shown that cold vulcanization usually takes place too slowly,

og særlig til vulkanisering av oppløsnings-middelholdige kautsjuk- eller kunstkaut-sjukblandinger er de hittil kjente vulka-niseringsmidler ikke tilstrekkelige i kul-den. and particularly for the vulcanization of solvent-containing rubber or synthetic rubber compounds, the vulcanizing agents known up to now are not sufficient in the cold.

With the help of these reaction products of polyvalent amines with ketones, it is possible in a short time at normal or moderately elevated temperatures to produce vulcanizates that satisfy all practical requirements.

Fremstillingen av disse kondensasjons-produkter kan skje etter i og for seg kjente metoder ved omsetning av flerverdige aminer med ketoner i nærvær av kondensasjonsmidler, f. eks. blyoksyd eller sinkoksyd. Det viste seg da at det ikke er nødvendig å skille det metalloksydholdige kondensa-sjonsmiddel fra reaksjonsblandingen etter omsetningen, men at det derimot er for-delaktig å la disse kondensasjonsmidler forbli i omsetningsproduktene av keton og flerverdig diamin, og å anvende det hele som vulkaniseringsmiddel. The production of these condensation products can take place according to methods known per se by reacting polyvalent amines with ketones in the presence of condensation agents, e.g. lead oxide or zinc oxide. It then turned out that it is not necessary to separate the metal oxide-containing condensing agent from the reaction mixture after the reaction, but that it is, on the other hand, advantageous to let these condensing agents remain in the reaction products of ketone and polyvalent diamine, and to use the whole as a vulcanizing agent.
