Background technique

In recent years, due to the occurrence of many domestic fire incidents on external insulation of building exterior walls, all walks of life have paid great attention to the fire performance of external insulation materials. At the same time, my country is transforming into a resource-saving, low-carbon and emission-reducing society, and building energy conservation is an indispensable part of the entire system's energy conservation. Actively developing new building materials with both fireproof and thermal insulation properties has always been an important development direction in the field of new building materials. In recent years, relevant enterprises and research institutes have also made many beneficial attempts, but there is still no thermal insulation with excellent performance of energy saving and thermal insulation. Materials are available. In recent years, the trade-off between building external insulation materials should focus more on fire performance or thermal insulation performance has been constantly changing. At present, the huge market space and relatively lagging technical level of my country's A-class fire protection materials make the market share shrinking continuously, and although organic thermal insulation materials have good thermal insulation performance, there are still hidden dangers in their fireproof performance.
