Anti-puncture combined shoe sole and manufacturing method thereof

Abstract

The invention relates to an anti-puncture combined shoe sole and a manufacturing method thereof. The anti-puncture combined shoe sole is characterized by comprising a foamed EVA (Ethylene-Vinyl Acetate) middle sole and a rubber outer sole, wherein an anti-puncture middle cloth layer which is matched with the top shape of the rubber outer sole is further arranged between the foamed EVA middle sole and the rubber outer sole; an EVA rubber film is arranged between the top of the anti-puncture middle cloth layer and the foamed EVA middle sole; a layer of EVA rubber film is further arranged between the bottom of the anti-puncture middle cloth layer and the top of the rubber outer sole; the foamed EVA middle sole, the anti-puncture middle cloth layer and the rubber outer sole are jointed into a whole by hot pressing; the anti-puncture middle cloth layer comprises over three layers of anti-puncture compact fabrics; a layer of EVA rubber film is arranged between every two adjacent anti-puncture compact fabrics; all layers of anti-puncture compact fabrics are jointed integrally by hot pressing. The sole and the method can be widely applied to the manufacturing process of shoes made by a bonding process.

Description

technical field [0001] The invention relates to a shoe sole and a manufacturing method thereof, in particular to a puncture-proof combined shoe sole suitable for the production of shoes by bonding process and a manufacturing method thereof. Background technique [0002] At present, the soles of finished shoes are usually composed of rubber and plastic outsoles, midsoles and insoles, which do not have puncture resistance. However, in some special environments, such as mines, earthquake relief, jungle exploration, army training and combat, etc., the soles are required to have certain puncture resistance, so as to prevent sharp objects such as bamboo sticks and steel nails from penetrating the soles and causing injuries. foot. In order to make the finished shoes have puncture-resistant properties, materials such as steel plates, aramid fiber, and glass fiber cloth are usually used to make puncture-resistant midsoles, so as to ensure the puncture-resistant effect of the soles. ...

Problems solved by technology

But because this material does not bond well with adhesives, it is difficult to bond it firmly to the sole
