Light rubber boot vamp rubber compound

Abstract

The invention discloses a light rubber boot vamp rubber compound. Rubber materials comprise natural rubber, high styrene rubber, thermoplastic styrene butadiene rubber, sulfur, stearic acid, activatedzinc oxide, antiaging agent MB, antiaging agent 264, light white carbon black, hollow glass beads and phenolic resin, the specific gravity of the light white carbon black is 1.2 to 1.5, and the specific gravity of the hollow glass beads is 0.18 to 0.21; the light rubber boot vamp rubber compound has the characteristics of high adhesive content and light specific gravity, and the tensile strengthis greater than or equal to 14Ma, the extension is greater than or equal to 500%, the light rubber boot vamp rubber compound is used for special protective rubber boots (such as various industrial andmining boots); the weight up to 2.4 Kg-3. 4Kg of one pair of original protective rubber boots can be successfully reduced to about 2.2 Kg-3. 1Kg; for miners with very large daily walking amount and workload, the load is obviously reduced, and under the conditions of high glue content and small reinforcing agent dosage, the protective boots have small calendering shrinkage, clear patterns and goodvamp stiffness, and the problems of large calendering shrinkage, unclear patterns, poor vamp stiffness and the like caused by the high glue content, small reinforcing agent dosage and the like are solved.

Description

technical field [0001] The invention relates to the field of rubber boot materials, in particular to a lightweight rubber boot upper mixed rubber material. Background technique [0002] The existing boots generally have the problem of heavy weight and are inconvenient to wear. For example, the specific gravity of traditional hot-vulcanized rubber boots is generally around 1.30-1.40, and the entire pair of rubber boots is heavier. Generally, from ordinary rain boots to special protective rubber boots, it is 1000 grams to 3500 grams per pair, especially special protective rubber boots (such as heavy industrial and mining boots) ), and the rubber material for boots consumes more than 1.2 kg per pair, which has a certain impact on the protection work. And foamed rubber has lighter performance than non-foamed rubber, although existing rubber is lighter in weight after foaming, but mechanical property is not ideal, can only be used in the lower rain boot material of performance r...

[0002] The existing boots generally have the problem of heavy weight, which is very inconvenient to wear

For example, the specific gravity of traditional hot-vulcanized rubber boots is generally around 1.30-1.40, and the entire pair of rubber boots is heavier. Generally, from ordinary rain boots to special protective rubber boots, it is 1000 grams to 3500 grams per pair, especially special protective rubber boots (such as heavy industrial and mining boots) ), and the consumption of boot surface rubber per pair is more than 1.2 kg, which has a certain impact on the protection work

And foamed rubber has lighter performance than non-foamed rubber, although existing rubber is lighter in weight after foaming, but mechanical property is not ideal, can only be used in the lower rain boot material of performance requirement, and limited lifespan
