It is reported that China is the world's leather processing center and a major leathermaking country. China processes 1.7 billion leathers such as pigs, cattle and sheep each year, and produces approximately 1.4 million tons of leather waste. Most of them are discarded except for a small amount. The environment has caused serious pollution, and the available resources such as high quality collagen and chromium oxide have been largely lost. Therefore, the utilization of leather waste resources has become an important topic of common concern at home and abroad.
Zhejiang Province is not only a major province of leather processing and manufacturing in China, but also a strong province for the production of plastics and rubber products. This provides a good platform for the use of leather waste powder. Zhejiang Fengli, which has achieved outstanding achievements in the field of powder engineering and green environmental protection equipment, and the Ningbo Institute of Technology, which has made breakthrough progress in the research and development of leather waste recycling, can be described as a combination of excellence and uniqueness.
At present, the domestic use of ordinary comminution equipment to smash leather waste, crushed after the skin particle size is larger, can only be applied to the production of recycled leather, recycling low added value. If skin powders are to be used in modified plastics and rubbers, sufficient fineness must be achieved before they can be used to increase the compatibility of plastics and rubbers with the skin powders.
In response to this situation, Zhejiang Fengli and Ningbo Institute of Technology will use a unique design of special crushing shear technology, leather ultra-fine grinding technology equipment to smash leather waste, using the carboxyl or amino group of collagen in collagen powder through a compatibilizer or The chemical reaction changes the skin powder, improves the compatibility of the skin powder and the rubber-plastic material, and obtains a composite material with good performance. As a filler of the rubber product, the production cost of the rubber product is reduced, and the leather waste powder and rubber are improved. Capacitive, improve the mechanical properties of rubber and prolong its service life.
The research and development of the project will reduce the cost of rubber and plastic products by replacing or reducing the amount of petroleum resin used in the recycling of leather waste, and will open up a new way for the recycling of leather waste resources.
