By the data in the table 1 as can be seen, compare with the propping agent C1 that does not add carbon nanotube in the matrix coating layer, the propping agent that the present invention prepares has better crush resistance energy, and the ability of anti-collision, wearing and tearing all is greatly improved.
In addition, by more as can be seen, when the content of carbon nanotube between the 0.5wt% to 1wt% the time, the crush resistance of propping agent sample can be more excellent, analyzing its major cause is: when content of carbon nanotubes is low, its play optimize the resin glue internal networking structure ability a little less than, the improvement of the wear-resistant ability of matrix coating layer is also not obvious; And content of carbon nanotubes is when too high, be equivalent to that cross-linking set rolls up in the resin glue, the rigidity of its network also increases thereupon, causes the resin glue flexility to reduce, rigidity disruptive probability takes place in collision and extrusion process to be increased, and finally causes the wear-resistant ability of matrix coating layer to weaken.
Obviously, the foregoing description only is for example clearly is described, and is not the qualification to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still belong among the protection domain of claim of the present invention.
