Description

Вулканизованные гидролиза полихлоропреновые латексы обладают очень большой стабильностью и не желатинируютс  обычным дл  хлоропреновых латексов желатинирующим агентом - окисью цинка . Это обсто тельство не позвол ет получить из вулканизованных полихлоропреновых латексов такие издели  широкого потреблени , как латексна  губка, резинова  обувь, игрушки, издели  санитарии и гигиены и другие издели . Между тем получение таких изделий из вулканизованного полихлоропренового латекса позвол ет исключить процесс гор чей вулканизации готовых изделий, и тем самым устранить непри тный запах, характерный дл  резин из полихлоропренового каучука, подвергнутых гор чей вулканизации.Vulcanized hydrolysis polychloroprene latexes have a very high stability and are not gelled by zinc oxide, the usual gelling agent for chloroprene latexes. This circumstance does not allow such consumer goods such as latex sponge, rubber shoes, toys, sanitation and hygiene products and other products to be obtained from vulcanized polychloroprene latexes. Meanwhile, the production of such products from vulcanized polychloroprene latex eliminates the process of hot vulcanization of finished products, and thereby eliminate the unpleasant smell characteristic of rubber from polychloroprene rubber subjected to hot vulcanization.

Известно применение амонийных солей совместно с окисью цинка дл  желатинировани  латексных смесей (см. патент США 2885372 с приоритом от 5.V-1959 г.).The use of ammonium salts in conjunction with zinc oxide is known for the gelatinization of latex mixtures (see US Pat. No. 2,885,372 with priority from 5.V-1959).

Предлагаемый способ желатинировани  латексных смесей отличаетс  тем, что в качестве желатинируюшего агента примен ют сульфат аммони  в количестве 2-4 вес. ч. на 100 вес. ч. сухого каучука. При осуществлении способа латексна  смесь после введени  сульфата аммони  нагреваетс  до температуры 80-90 и выдерживаетс  при этой температуре 5-15 мин.The proposed method for gelating latex mixtures is characterized in that 2-4% by weight of ammonium sulfate is used as a gelating agent. hours per 100 weight. h. dry rubber. In the process, the latex mixture after the introduction of ammonium sulfate is heated to a temperature of 80-90 and kept at this temperature for 5-15 minutes.

При этом латексна  смесь сохран ет свою стабильность при комнатной температуре в течение нескольких суток, что создает удобства в работе, особенно при непрерывном процессе получени , например, губки. № 142763-2 .МШИП .
