Problems solved by technology

Due to the poor compatibility between the flame retardant and the resin matrix, it often leads to the decline of mechanical properties and the uneven appearance. The flame retardant effect of the current encapsulation coating used for airgel is not ideal, and there is still a large room for development and improvement

Abstract

The invention provides a packaging flame-retardant coating for aerogel and a production process thereof, and the packaging flame-retardant coating comprises the following raw materials in parts by mass: 20-100 parts of a resin matrix, 40-100 parts of a compound flame retardant, 60-100 parts of a water solvent, 2-10 parts of carbon black color paste, 2-20 parts of a chemical additive, 1-8 parts of a thickening agent and 1-25 parts of a curing agent, the resin matrix is any one or two or more of epoxy resin, polyurethane resin, acrylic resin and silicone rubber; the compound flame retardant is any one or two or more of a metal hydroxide flame retardant, a phosphorus flame retardant and a nitrogen flame retardant. The flame-retardant packaging coating provided by the invention has the advantages of wide material sources, no need of large precise instruments, simple production process and wide application range, and the obtained flame-retardant coating has excellent flame-retardant and high-temperature-resistant characteristics, excellent mechanical properties, chemical resistance and high adhesive force.

Description

Technical field [0001] The invention relates to an encapsulated flame retardant coating for airgel and its production process, belonging to the field of flame retardant coatings. Background technique [0002] my country's aerogel production capacity has exceeded 55,000 cubic meters, the industry scale has exceeded 600 million yuan, and market demand is growing year by year. Its advantages of low carbon, environmental protection and energy saving echo the national policies and international energy situation, and have good development prospects. [0003] As the material with the smallest density in the world, aerogel's loose and porous structure gives it extremely low thermal conductivity and excellent heat insulation, heat preservation, and thermal stability properties, making it useful in power battery protection, industrial pipelines and equipment insulation, energy saving, and new applications. Energy buses are widely used in flame retardant, building insulation and other...
