Non-expansive epoxy-group ceramifiable fireproof coating material and preparation method thereof

The invention discloses a non-expansive type epoxy group ceramifiable fireproof coating material and a preparation method thereof, and belongs to the technical field of fireproof coatings. The non-intumescent epoxy group ceramifiable fireproof coating material is composed of a component A and a component B. The component A comprises the following components in parts by weight: 10-20 parts of epoxy resin, 5-10 parts of a curing agent and 0.04-0.06 part of an accelerant. The component B is prepared from the following components in parts by weight: 10 to 20 parts of zinc phytate hybridized two-dimensional burning-resistant filler, 15 to 25 parts of alkaline earth metal glass powder and 5 to 10 parts of modified ceramic forming aid; the modified ceramic forming aid is one or a mixture of two of modified ammonium polyphosphate and modified melamine polyphosphate; the mass ratio of the component A to the component B is 1: (1.1-1.5). The non-expansive type epoxy group porcelainized fireproof coating material provide
