Abstract

The invention provides a nano composite heat-insulation material and a preparation method thereof. The nano composite heat-insulation material is characterized in that a flame-retardant glue layer, analuminum foil layer and an aerogel layer are successively arranged on one side of a flame-retardant bubble layer; and the flame-retardant bubble layer consists of hexagonal bubble structures which are arranged in a cellular manner, and comprises 50-85 parts by weight of low-density polyethylene and 20-60 parts by weight of a compound flame retardant. The compound flame retardant comprises the following components in parts by weight: 10-12 parts of nano aluminum oxide, 16-18 parts of silicon nitride, 20-30 parts of phenolic resin, 10-30 parts of an ethylene-vinyl acetate copolymer and 2-8 parts of a silane coupling agent. By the hexagonal bubble structures which are arranged in the cellular manner and the compound flame retardant, ventilation paths are reduced, the content of oxygen is reduced, and the combustion value of an aluminum foil bubble heat-insulation material is decreased.

Description

【Technical field】 [0001] The invention relates to the field of thermal insulation materials, in particular to a class A flame-retardant aluminum foil air bubble thermal insulation material and a preparation method thereof. 【Background technique】 [0002] The energy consumed by industrial buildings and maintaining a comfortable indoor temperature accounts for more than 30% of the world's total annual energy consumption. The use of thermal insulation materials can improve the energy utilization rate of buildings and reduce energy consumption. However, the thermal conductivity of inorganic thermal insulation materials is generally high, traditional organic thermal insulation materials are generally flammable, and the use of organic flame retardants will cause harm to the environment and human health. In recent years, there have been many fire accidents caused by the low fireproof performance of thermal insulation materials, such as the 2009 CCTV building fire in Beijing. There...
