Abstract

The intumescent fireproof coating disclosed by the present invention is composed of two components A and B. The component A uses epoxy resin as the main film-forming substance, and is added with modified resin, catalyst, char-forming agent, foaming agent, flame retardant, Flux, pigments and fillers, smoke inhibitors, component B is composed of pigments and fillers, curing agent, auxiliary agent; the epoxy resin is selected from bisphenol A type epoxy resin, bisphenol F type epoxy resin, TDE- 85 epoxy resin, hydantoin epoxy resin, etc.; the modified resin is selected from polyurethane, furan resin, amino resin, bisphenol F resin, etc.; the dosage ratio of components A and B is 2-4:1. The fireproof coating has good fireproof and heat insulation performance, good adhesion, high strength, and can withstand the influence of high and low temperature cycles. The coating has good water resistance, acid and alkali resistance, salt corrosion resistance, excellent flexibility, and is not easy to fall off. Stable storage, convenient construction, etc., suitable for indoor and outdoor steel, aluminum, etc., especially suitable for fire prevention occasions in offshore oil platforms, oil fields, refineries and petrochemical plants.

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 ...
