Abstract

The invention relates to epoxy expansion type fireproof coating enhanced by various carbon-based materials. The epoxy expansion type fireproof coating is prepared from a component A and a component Baccording to the weight ratio of 3 to 1, wherein the component A is prepared by taking epoxy resin as a film-forming matter, and adding a foaming flame-retarding system (composed of a carbon-forming catalyst, a carbon-forming agent and a foaming agent), a carbon-forming enhancer, a toughening agent, a graphene substance, expanded graphite, carbon fiber, pigment and filler and an auxiliary agent; the component B is composed of a curing agent, the auxiliary agent and the pigment and filler. According to the epoxy expansion type fireproof coating enhanced by various carbon-based materials, provided by the invention, the technical problems that a fireproof coating layer is easy to crack and fall off are solved; the epoxy expansion type fireproof coating is applicable to safety protection of occasions which easily have hydrocarbon fire disasters, such as tunnels, chemical plants and marine oil production platforms.

Description

technical field [0001] The invention relates to the field of fireproof coatings, in particular to an epoxy expansion type fireproof coating reinforced by various carbon-based materials. Background technique [0002] With the development of my country's chemical industry and the acceleration of offshore oil exploration, the scale of offshore oil production platforms and large-scale chemical construction is increasing. In the process of urbanization and building development, tunnels have become an indispensable part of traffic planning. However, in these tunnels, chemical plants and offshore oil production platforms, there is a certain probability of hydrocarbon fires due to rich organic chemical raw materials. The heating and propagation speed of hydrocarbon fire is fast, and the shock wave generated by explosion may also be accompanied during the combustion process. Therefore, in these places composed of organic polymer materials, it is necessary to use hydrocarbon-resista...
