Abstract

The invention provides a nanometer composite heat-insulating material. The nanometer composite heat-insulating material comprises a flame-resistant bubble layer and is characterized in that a flame-resistant glue layer, an aluminum foil layer and an aerogel layer are arranged on one side of the flame-resistant bubble layer sequentially; the aerogel layer is prepared from the following components in parts by weight: 5 to 20 parts of silicon dioxide-phenolic resin composite aerogel, 20 to 30 parts of epoxypropane, 80 to 130 parts of acetic acid, 50 to 70 parts of polyethylene glycol 600, 10 to 30 parts of formamide, 20 to 30 parts of toluene diisocynate tripolymer and 10 to 15 parts of isophorone diisocyanate tripolymer. Through the silicon dioxide-phenolic resin composite double-network structure aerogel, the adhesiveness of the aerogel and the aluminum foil can be improved and the heat-insulating property of the material is improved.

Description

【Technical field】 [0001] The invention relates to the field of thermal insulation materials, in particular to a nanocomposite 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. Silica airgel nanomaterials have excellent thermal insulation performance, and its stable three-dimensional space network structure can eliminate the internal convection of the gas. At the same time, the gas molecules in the pores are difficult to collide or the probability of collision is very small, so that the heat conduction of the gas is also large. In order to reduce, and the Si-O-Si group skeleton greatly increases the path of heat transfer in the solid skeleton of ...
