Manka¬ mentem stosowania obu ukladów srodków wul¬ kanizujacych do produkcji gumy piankowej jest uzyskiwanie niedoskonalej struktury piany la¬ teksowej, co uniemozliwia otrzymanie wyrobu go¬ towego o nizszym ciezarze wlasciwym, a tym sa¬ mym mniejszym koszcie wytwarzania.Celem wynalazku bylo unikniecie powyzszych mankamentów i opracowanie ukladu przyspiesza¬ czy zapewniajacego wlasciwy przebieg procesu wulkanizacji oraz optymalne obnizenie ciezaru wlasciwego gumy piankowej przy zachowaniu wszy¬ stkich innych parametrów fizyko-chemicznych.Zaskakujacy efekt uzyskano poprzez zastosowa¬ nie do wulkanizowania mieszanki gumowej w lacznym dzialaniu 1—2 czesci na wage kauczuku etylofenylodwutiokarbaminianu cynku, 2—3 czesci 10 30 siarki wraz z mieszanina 0,5—1,5 czesci wago¬ wych aromatycznych merkaptydów cynku i przy¬ spieszacza dwufenyloguanidyny 0,5—1 czesci wa¬ gowych. Caly proces odbywa sie w temperaturze 100—140°C w atmosferze nasyconej para wodna.Dzialanie aromatycznych merkaptydów cynku i przyspieszacza dwufenyloguanidyny powoduje wzrost twardosci gumy piankowej — przez co mozna poprawic strukture gumy piankowej. Za¬ leca sie przygotowanie lacznej dyspersji wodnej etylofenylodwutiokarbaminianu cynku (przyspie¬ szacz EFK) oraz mieszaniny aromatycznych mer¬ kaptydów cynku (przyspieszacz Tiazin) o zawar¬ tosci 33—50% suchych skladników oraz wydzielo¬ nej dyspersji wodnej dwufenyloguanidyny (przy¬ spieszacz D) o zawartosci 20% jego masy w dys¬ persji. Przyrzadzanie dyspersji nastepuje wedlug powszechnie znanych sposobów na urzadzeniach tego typu jak: mlyny kuleczkowe róznych typów oraz mlynach kulkowych. Korzystne wyniki osia¬ ga sie jezeli dyspersje przyspieszacza dwufenylo¬ guanidyny wprowadzi sie do mieszanki lateksowej zawierajacej juz srodki pianotwórcze, wulkaniza¬ cyjne, wypelniacze i antyutleniacze na krótko przed uzyciem mieszanki do procesu spieniania.Przyklad I.

Known methods of vulcanizing foam rubber based on a mixture of natural and synthetic - butadiene - latex. In the styrene process, primary accelerators of the zinc carbamate type and secondary accelerators of markaptobenzothiazole or the zinc salt of markaptobenzothiazole were used in conjunction with the condensation product of formaldehyde, ammonia and ethyl chloride or diphenylguanidine. The disadvantage of using both systems of vulcanizing agents for the production of foam rubber is the fact that the structure of the latex foam is not perfect, which makes it impossible to obtain a finished product with a lower specific weight, and thus a lower production cost. The aim of the invention was to avoid the above-mentioned drawbacks. and the development of a system ensuring the proper course of the vulcanization process and the optimal reduction of the specific weight of foam rubber while maintaining all other physico-chemical parameters. A surprising effect was obtained by using a rubber mixture for vulcanization in a total action of 1-2 parts on the weight of rubber zinc ethylphenyl dithiocarbamate, 2-3 parts of sulfur together with a mixture of 0.5-1.5 parts by weight of aromatic zinc mercaptides and a diphenylguanidine accelerator 0.5-1 parts by weight. The whole process takes place at a temperature of 100-140 ° C in an atmosphere saturated with water vapor. The action of aromatic zinc mercaptides and the diphenylguanidine accelerator causes an increase in the hardness of foam rubber - which can improve the structure of foam rubber. It is recommended to prepare a total water dispersion of zinc ethylphenyl dithiocarbamate (accelerator EFK) and a mixture of aromatic zinc mercaptides (accelerator Tiazin) containing 33-50% of dry ingredients and a separate water dispersion of diphenylguanidine (accelerator D). containing 20% of its weight in the dispersion. The dispersion is prepared according to commonly known methods on such devices as: ball mills of various types and ball mills. Favorable results are obtained when the diphenyl guanidine accelerator dispersions are incorporated into a latex mixture already containing foaming agents, vulcanizers, fillers and antioxidants shortly before the mixture is used for the foaming process. Example 1 A latex mixture of the following composition is foamed, formed, and then vulcanized at 120 ° in an atmosphere saturated with water vapor for a period of 25 minutes. 75 41675 416 Composition of the mixture 100.0 parts by weight of rubber - natural latex 60% - synthetic butadiene latex. - styrene 60% - rosin soap - sulfur - zinc ethylphenyl dithiocarbamate - a mixture of aromatic zinc mercaptides - diphenylguanidine - antioxidant - starch 50.0 "50.0" 1.2 "2.5" 1.2 "1.0" 0 , 5 "0.75" 4.5 "10 PL PL
