Embodiment Construction

[0034] The present invention is based on the discovery that soluble sulfur such as sulfur S 8 The ring is catalyzed by the zinc complex of dithiocarbamate combined with potassium octoate and sodium dodecylbenzenesulfonate (SDBS) surfactants to produce prevulcanized natural polystyrene in latex compositions. isoprene particles. The latex composition enables the production of latex film articles by dipping a former, coated with or without a coagulant, into the composition. Surfactant package inhibits agglomeration and flocculation of natural polyisoprene particles. Latex impregnated membranes have natural polyisoprene particles that become crosslinked, and the regions between the particles crosslink during vulcanization curing, forming internally and intercrosslinked bonds. The resulting article includes a high quality and uniform latex film.

[0035] A latex stabilizing composition is a composition that keeps native polyisoprene particles separated from each other in an aque...

Abstract

A shoe cover is a natural latex article with reduced amount of sulfur cross linking agent and accelerators including zinc dithiocarbamate that break catalytically soluble sulfur S8 sulfur rings forming sulfur linear chains. Surfactants present in the pre-vulcanization composition wets natural polyisoprene particles and permeates small sized sulfur into the interior of these particles thereby pre-vulcanizing the particles. The latex emulsion also has post-vulcanization composition with accelerators that crosslink between particles during the post vulcanization cure cycle. The dipped natural polyisoprene article is substantially uniformly cured both in the inter-particle and intra-particle regions and reliably exhibits high cross link density, uniform distribution of double bonds and zinc segregation at the boundaries or original particles. The natural rubber films exhibit high tensile strength, tensile modulus, tear strength, elongation with low modulus of the shoe cover. The bottom surface of the shoe cover is etched to produce a slip resistant surface.

Description

technical field [0001] The present invention relates to the production and method of a natural latex shoe cover with enhanced grip, which uses controlled pre-vulcanized natural latex particles, and is impregnated with an aqueous latex emulsion to form a thin latex article, so as to have improved intra-particle and inter-particle Bond. Shoe cover made of natural rubber with a non-slip sole with a fine structure etched and also covered with an acrylic coating that prevents rapid wear of the sole. The shoe cover includes a highly elastic natural rubber body that can be easily worn over regular smart shoes, thereby preventing the smart shoes from being exposed to moisture and mud. The natural latex used to mold the body of the shoe cover has reduced amounts of sulfur and other accelerator crosslinkers, and is vulcanized at a lower temperature reduced to only 110°C to 130°C, while providing about 800% elongation Rate. Background technique [0002] Natural latex shoe covers are...
