Abstract

The invention belongs to the technical field of fireproof coatings. The invention discloses a composite steel structure fireproof coating which comprises the following components in percentage by weight: 20%-30% of hydroxymethyl acrylamide modified acrylate, 15%-25% of composite ammonium phosphate, 15%-25% of high-performance sub-nanometer hollow glass beads, 15%-25% of tripentaerythritol, 10%-15%of nanometer aluminum oxide, 0.1%-0.5% of fluorocarbon modified polyacrylate and 3%-5% of propylene glycol methyl ether acetate. The fireproof coating provided by the invention has good fireproof andflame-retardant properties and mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of fireproof coatings, and in particular relates to a composite steel structure fireproof coating and a preparation method thereof. Background technique [0002] Steel structures are widely used in buildings. Without the protection of fire-resistant coatings, once a fire occurs, the temperature of the steel will rise rapidly after being burned by an open flame. When the temperature exceeds 540°C, the steel will start to soften, and the overall steel structure will be easily deformed. Collapse occurs, endangering the safety of life and property. Therefore, measures must be taken to protect steel structures from fire. The most widely and cost-effective method in practical engineering applications is to apply fire-resistant coatings for steel structures. The purpose of fire-resistant coatings for steel structures is to increase the fire-resistant limit of steel structures to the fire-resistant limit specified ...
