Description

technical field

[0001] The invention relates to a hot-melt adhesive film, in particular to an environment-friendly hot-melt adhesive film for bonding shoe material outsoles and midsoles and a preparation method thereof. Background technique

[0002] The structure of the sole is quite complex. In a broad sense, it includes all the materials that make up the bottom, such as the outsole, midsole and heel. The common characteristics of general shoe sole materials should be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, good elasticity, easy to fit the foot shape, not easy to change shape after setting, heat preservation, easy to absorb moisture, etc. bottom, when walking and changing feet, there are various conditions such as braking effect so as not to slip and easy to stop.

[0003] The material of the outsole is simply rubber, the most commonly used is SBS, the sole made of SBS instead of vulcanized rubber and polyvinyl ...
