Abstract

The invention discloses a multicomponent phenolic resin fire-retardant paint composition. The paint composition comprises a component (A), a component (B) and a component (C), wherein the component (A) at least comprises one phenolic resin; the component (B) at least comprises an epoxide resin; the component (C) at least comprises a curing agent of the epoxide resin and the phenolic resin; the component (C) and the components (A) and (B) are stored separately; and the components (A), (B) and (C) are mixed, a crosslinking curing reaction is generated. The paint composition related to the invention does not contain solvents, such as an organic solvent, water and the like, or a dispersing agent, is paste suitable for various coating processes and can be used for fire-retardant coating of a steel structure, concrete and wood. A formed coating has the obvious characteristics of high bonding strength, ageing resistance and hydrocarbon fire resistance.

Description

technical field [0001] The invention relates to a multi-component phenolic resin fireproof coating composition, in particular to an intumescent multi-component phenolic resin coating composition for fire prevention. Background technique [0002] At home and abroad, more attention is paid to the research and development of fireproof coatings. Many scientific research institutions and coating companies have carried out research and development of fireproof coatings, and have also developed many new varieties of fireproof coatings. At present, most of the production and research and development of fire retardant coatings at home and abroad are still based on the modification of P-C-N flame retardant systems, but the performance of fire retardant coatings is optimized by adding ammonium polyphosphate, pentaerythritol, melamine, etc. in different proportions. In the current common fire retardant coating formulations, the mass fraction of P-C-N fire retardant additives in the coat...
