Porous silica gel cement activated ceramic powder for fireproof cable as well as preparation method and application of porous silica gel cement activated ceramic powder

The invention relates to the field of chemical materials, in particular to porous silica gel cement activated ceramic powder for a fireproof cable and a preparation method of the porous silica gel cement activated ceramic powder. The ceramic powder comprises the following components in parts by weight: 20-40 parts of wollastonite powder, 40-60 parts of mica powder, 10-20 parts of fumed silica, 1-5 parts of a coupling agent and 1-3 parts of an activating agent. The preparation method comprises the following steps: adding the wollastonite powder, the mica powder, the fumed silica and the coupling activator material into a high-speed mixer, and mixing at a high speed of 50-120 DEG C for 40-60 minutes to obtain the activated modified ceramic powder. The stability can be improved through the wollastonite powder, the mica powder, the fumed silica and the combination of modification of the activating agent and the coupling agent, the cost is low, the preparation method is simple, and rapid production can be achieved
