Abstract
The invention discloses a preparation method of self-disperse nano-titaniummetalslurry. Nano-titaniummetalslurry having a self-disperse function is obtained in such a manner that mechanical effect generated by a self-made high-speed high-energy pulverizer and chemical effect of oligomer are integrated and applied to titaniumpowder. Production equipment is seen in the figure. The self-disperse nano-titanium metalslurry comprises following materials: 1000 parts by weight of industrial pure titanium powder, 50-100 parts by weight of crushing promoters, 50-100 parts by weight of crushing protective agents and 400-1000 parts by weight of dispersing agents. The material ratio of beads to titanium powder is 100:5-20. The material ratio of titanium powder to protective agents is 1000:1200-2000. The ratio of auxiliary shaft rotation speed to main shaft rotation speed is 2 to 8. Infinitely variable is adopted. The self-made high-energy high-efficiency pulverizer is utilized and shown in the figure. Black pulp separated by crushing is self-disperse nano-titanium metal slurry.
Description
technical field [0001] The invention relates to the preparation technology of metal nanometer materials, in particular to a preparation method of self-dispersing titanium nanometer metal powder slurry. The invention also relates to a self-made high-energy and high-efficiency pulverizer used in the preparation method. Background technique [0002] So far, with the development of nanomaterials preparation technology, almost all kinds of metals can be made into nanopowders. Nanomaterials have shown great prospects for improving the performance of polymers. However, the application of nanomaterials faces a difficult problem: how to quickly Well, dispersing it into organic polymer materials has not been well resolved. Nowadays, the dispersion of nanomaterials is the biggest technical bottleneck restricting the wide application of nanomaterials. [0003] Using low-molecular substances similar in nature to polymers, monomers that can be polymerized on the solid surface, or using ...
