Abstract

The invention discloses the inflatable fire-resisting paint, comprising A and B. The A comprises epoxide resin, modified resin, catalyst, foamable agent, fire retarding agent, fluxing agent, color filler and smog inhibiting agent, and the B comprises color filler, curing agent and auxiliary agent. The fire-resisting paint has the advantages of good heat-insulating property, adhesion force and intensity. The coating has good water resistance, acid- alkali resistance, corrosion resistance and tenacity, and is not easy to drop. The paint can be used in rolled steel and aluminum products, especially the fireproof situation of oil factories.

Description

technical field [0001] The invention relates to an intumescent fire-proof coating, which is suitable for indoor and outdoor steel, aluminum and other materials from cellulose and hydrocarbon flames, fire spray and explosion, and maintains the efficacy of materials within a certain period of time. Compared with traditional intumescent fireproof coatings, the present invention is more suitable for offshore oil platforms, oil fields, oil refineries and petrochemical plants, etc. Background technique [0002] In terms of fire prevention mechanism, fire retardant coatings are generally divided into two types: intumescent and non-intumescent. When the non-expansive fire retardant coating is exposed to fire, the coating basically does not change in volume, and the thermal conductivity of the coating is low, which delays the speed of heat transfer to the protected substrate. The fire retardant coating itself is non-combustible, which acts as a barrier to the substrate and prevents ...
