Abstract： |
Disclosed is a powder natural rubber modified by carbon nanostructured pipe and the preparing method, relating to the field of modifying macromolecular material with CNTs. Said powder natural rubber is characterized in that it possesses carbon nanostructured pipe which is 1%~50% of the glue of natural latex in mass.The method comprises conducting surface treatment forCNTs to make it hydrophilism: mixing it with dispersant and deionized water and getting the CNTs-water slurry; modifying the pH value to 9~12; mixing with natural latex and getting the natural rubber liquid latex added with CNTs. Then preparing modified powder natural rubber containing CNTs with the method of spray-drying, the quantity of input is 5%~30%, the temperature is 100~180DEG C. The prepared powder rubber is characterized by the adequate distribution of the CNTs in the product, the small size, and the dramatically increased mechanics property compared with the traditional powder rubber. |
