Abstract
The invention discloses a method for researching a modification technology of high-activity single-variety shoe material powder, which is used for efficiently preparing ultramicro active shoe materialpowder by utilizing a normal-temperature continuous solid-phase mechanochemical crushing and force activation technology. The technology can break through the problems that superfine grinding, forceactivation cross-linking and high-toughness leather-making and shoe-making solid waste are difficult to achieve in the prior art and equipment, and is an important way for recycling, harmlessness andindustrialization treatment of single-variety shoe material leftovers. According to the technical scheme, the method comprises the following steps: firstly, classifying and recycling, separately treating different types of shoe material wastes, crushing and collecting the classified shoe materials by using a double-roller open mill, and then performing superfine grinding and solid-phase shearing and grinding by using a solid-phase mechanochemical mill, thereby finally obtaining active single-variety shoe material powder. The technology can be operated at normal temperature and is high in large-scale production and output efficiency. And moreover, the method highly meets the national resource circulation strategy requirements, no chemical additive is added, and no secondary pollution is caused.
