In this project, wet grinding system, homogenizing feeding device and heating and pressure boosting system are used to adjust the proportion of coupling agent and coating rate of finished product through parameters. To seek the best process parameters and develop new products suitable for the rubber and plastic field. The objective of the research and development of key products approved by the special screening and surface treatment, with rubber has very good crosslinking effect, it has good compatibility with the matrix material, good dispersibility, high purity and chemical inertness strong wait for an advantage, so can effectively improve the rubber material insulation performance, mechanical property and processing rheological properties, aging resistance and acid-proof alkaline, etc.

After the implementation of the project, the coal measures kaolinze well retain the complete flake structure, with fine particle size, narrow distribution, high whiteness, low impurity content, and has a good reinforcing effect on rubber and plastic. The filled colloidal particles have strong coloring power and high opacity. Good processing performance, rubber and plastic to technical indicators of the material is an excellent reinforcing filler. At the same time, it can be coupled with polymers to enhance the mechanical properties of plastics, improve the hydrophobicity and aging resistance of engineering plastics, and improve the processing performance, improve the dimensional stability of rubber and plastic products, less deformation, reduce the density of products and other aspects of the effect is significant, and can also improve the color purity and gloss of products.

After the successful implementation of the project, the rubber and plastic grade kaolin products have filled the domestic gap and entered the ranks of international advanced products. After the completion of the project, the sales revenue of 50 million yuan and profits and taxes of more than 10 million yuan will be increased. This project is extended to the coal measure kaolin processing industry in our province, which can reduce the area of coal gangue and restore the ecological environment every year. It not only brings considerable economic benefits, but also plays a positive role in improving the quality of calcined kaolin products in China and promoting the rapid development of non-ceramic coal measure kaolin resources.
