The product performance effect is most obvious when the two are blended and coordinated. The performance of the products tended to deteriorate when diatomite agent was not added to the modified additive, lanthanum oxide and citric acid were not added to the diatomite agent, carbon nanotube liquid was not added to the modified additive, and carbon nanotube and silane coupling agent KH560 were not added to the carbon nanotube liquid; The modified additive obtained by the specific method of the present invention has the most significant product performance effect, and the specific carbon nanotube liquid combined with the specific diatomaceous earth agent has the most significant product performance effect; The performance of the products without adding nano bentonite to the additives, replacing nano bentonite with nano bentonite, without adding melamine to the additives, and without adding auxiliary adjusters to the additives all showed a trend of deterioration to varying degrees, and the performance of the products without adding auxiliary adjusters also showed a more obvious trend of deterioration; At the same time, the performance of the product tended to deteriorate when silicon carbide whiskers and stearic acid, yttrium nitrate solution, sodium alginate solution and nano-silica sol were not added to the auxiliary agent; The auxiliary agent obtained by the specific method of the present invention is combined with the nano-bentonite agent and melamine body of the present invention to obtain the auxiliary additive, and the product performance effect is the most significant. Other methods are not as obvious as the effect of the present invention.
