Abstract

The invention discloses fire-protection powder coating used for steel structure workpieces and a method for producing the same, belonging to the technical field of building coating. The fire-protection powder coating of a steel structure is produced from polyester resin, epoxy resin, solidifying agent, ammonium polyphosphate (II), melamine, pentaerythritol, melamine pyrophosphate, flatting agent, degasifying agent, flowable agent, pigment, filler and titanate coupling agent. The fire-protection powder coating of a steel structure has the advantage of good intumescent and heat-insulating effect, thereby being applicable to various steel structure workpieces.

Description

technical field [0001] The invention relates to an intumescent steel structure fireproof powder coating and a preparation method thereof, belonging to the technical field of architectural coatings. Background technique [0002] With the advancement of technology and social development, people pay more and more attention to environmental protection. Powder coatings with "economy, environmental protection, high efficiency and energy saving" have been developed rapidly. are getting more and more attention. In the research of intumescent fireproof coatings for steel structures, the coupling agent can improve the fireproof performance of the coating, and the effect is obvious, but its use methods and purposes are different. Chinese patent ZL200610045472.4 uses titanate coupling agent to treat inorganic fillers. The method is to treat with alkali solution first, then soak in titanate coupling agent solution, then filter and dry. It is mainly used for the production of pipeline an...
