The beneficial effects of the invention are as follows：
Technical solution of the present invention, during the preparation process, firstly, by fatty acid, alcohol, ethyl orthosilicate, isocyanates, nano metal
Powder mixing then adds sulfuric acid as catalyst, is catalyzed fatty acid and esterification, in esterification reaction process, one occur for alcohol
Denier generates water, and the water of generation is just reacted with the ethyl orthosilicate in system, improves direct hydrolysis method because of precipitating reagent local concentration
Non-uniform phenomenon caused by excessively high, ensure that the uniformity of hydrolysis, be conducive to good point of nano silica generated
It is dispersed in system, secondly, the isocyanates in system is reacted with water, generates carbon dioxide and amine substance, the titanium dioxide of generation
Carbon is conducive to the dispersion of the nano silica in system, and the amine substance of generation can adsorb the nanometer titanium dioxide just generated
Silicon avoids nano silica nucleus continued growth, makes the size controlling of the nano silica generated in nano-scale, together
When, the sulfuric acid in system enables to the protonated amino on amine substance surface effectively to avoid since like charges are mutually exclusive
Nano silica reunion again, carbonizes to obtain the nano silica of the uniform purity is high of particle diameter distribution in pressure maintaining
In the process, the amine substance charing of nano silica is loaded, and generates tar, protects the tar generated
It stays in system, the tar of generation can promote the interface cohesion between nano silica and rubber, effectively avoid nanometer titanium dioxide
Silicon is reunited in mixing process, further improves the dispersion performance of product.
