| description | The invention belongs to the technical field of composite materials, and specifically relates to a preparation method of a silicone-titanium dioxide composite material. The method comprises the stepsthat step 1, methyl trichlorosilane is added into toluene and stirred evenly, then titanium tetrachloride is added, and ultrasonic stirring is conducted until the mixture is stirred evenly to obtain mixed toluene solution; step 2, distilled water is slowly and dropwise added into the mixed toluene solution, and microwave reaction is conducted for 2-4h untilan acidic colloidal hydrolysate is formed; and step 3, ammonia gas is introduced to adjust pH to neutrality, then a catalyst is added, and a condensation polymerization reaction is conducted at elevated temperature and pressure until a three-dimensional network structure is formed to obtain the silicone-titanium dioxide composite material. The method has the advantages of simple process, and short production cycle, and the product, namely the silicone-titanium d |
