Abstract

The invention discloses an aerogel composite modified fire retardant and its preparation method and application. The aerogel composite fire retardant is formed by composite processing of silica aerogel particles, ammonium biphosphate, diammonium phosphate, sodium dodecanesulphonate and urea which are used as raw materials. The hydrophobic silica aerogel particle composite modified fire retardant provided by the invention has excellent fire resistance, heat preservation and insulation performance, sound insulation performance and light weight. Thus, problems of high heat conduction, heavy weight, high water absorption and the like of a traditional fire retardant are solved. The fire retardant provided by the invention can be used for fire protection and modification of building materials and in the fields of various cloth materials, plywood and the like. By the use of the product provided by the invention, safe and reliable fireproof guarantee can be provided for high-rise buildings, public amenities, hotels, residential buildings and the like.

Description

technical field [0001] The invention relates to a functional additive for flammable polymers, in particular to an airgel composite modified flame retardant and its preparation method and application. Background technique [0002] In recent years, urban buildings have become higher and higher, and fires in high-rise buildings have emerged one after another, and have become more and more intense. As a big real estate country, our country pays more and more attention to building safety and fire prevention, especially the Beijing CCTV building and Shanghai "11.15" fire caused by the external thermal insulation material of the external wall, which has caused the relevant national authorities to pay attention to the external thermal insulation material of the external wall. The Ministry of Public Security also issued Document No. 65 in mid-March 2011 to strengthen the fire performance requirements of external thermal insulation materials for residential buildings. Among the tradi...
