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.

Description

technical field [0001] The invention belongs to the field of modification and recycling of waste polymer materials, and in particular relates to a research method for modification technology of high-activity single-variety shoe material powder. Background technique [0002] Footwear Shoemaking is a traditional advantageous industry in China, ranking first in my country's light industry, and has become a major pillar of China's economy. The solid waste (scrap and defective products) of the shoemaking industry has a wide variety of types, complex components, and a large amount of solid waste from shoemaking. The existing treatment methods for these wastes are usually landfill or incineration, or simple grinding and granulation , not only causes serious environmental pollution and endangers human health, but also has problems such as low resource utilization rate, making it difficult to recycle with high value, which has become a bottleneck for the green and sustainable develop...
