Nano-coated modified silicon graphene material and preparation method thereof
The invention discloses a nano-coated modified silicon graphene material and a preparation method thereof, and belongs to the technical field of new materials. The preparation method comprises the following steps: heating the glass fiber, the silica powder, the allyl isocyanate, the absolute ethyl alcohol and the coupling agent; adding 1-tricyclic [3.3. 1.1 (3.7)] decanol and graphite polystyrene particles, and heating; finally, adding tert-butyl N-allyl carbamate and a defoaming agent, and carrying out thermal reaction and ultrasonic treatment to prepare a silicon graphene material; the preparation method comprises the following steps: mixing a nano-scale inorganic flame retardant, azodicarbonamide and hexadecylamine, homogenizing, and reacting in a nitrogen atmosphere to obtain a flame-retardant composite nanomaterial; the preparation method comprises the following steps: adding fly ash into a polyether derivative, then adding a silicon graphene material, centrifuging to collect a precipitate, and then adding a flame-retardant composite nano material, thereby obtaining the flame-retardant composite nano material. Various physical properties of the silicon graphene material can be remarkably improved, including improvement of compressive strength and tensile strength, reduction of thermal conductivity and improvement of combustion performance, so as to adapt to harsh application requirements of building materials.
