Abstract

The invention discloses a low-thermal-conductivity phase-change energy-storage thermal-insulation board as well as a preparation method and application thereof. The low-thermal-conductivity phase-change energy-storage thermal-insulation board comprises a core board structure and a multifunctional skin layer structure covering the surface of the core board structure; a phase-change material is packaged in the multifunctional skin layer structure; the core board structure comprises a uniform porous material serving as a reinforcing material and a thermal-insulation foam material; and the thermal-insulation foam material is filled and distributed in the uniform porous material. The phase-change material filled in the skin layer absorbs a large amount of heat and stores the heat in the heating process, the heat is slowly released in the heat release process, and the heat insulation performance of the phase-change energy-storage insulation board can be greatly improved by matching with the foam material with low thermal conductivity. In addition, the thermal-insulation foam material in the uniform porous material plays a role in heat insulation, so that the low-heat-conductivity phase change energy storage heat insulation plate with the phase change energy storage function is realized.

Description

technical field [0001] The invention relates to a thermal insulation board, in particular to a low thermal conductivity phase-change energy storage thermal insulation board suitable for alpine regions, a preparation method and application thereof, and belongs to the technical field of thermal insulation materials and building materials. Background technique [0002] According to the data of the International Energy Agency, the proportion of global building energy consumption is gradually increasing. In 2018, the proportion of global building energy consumption has risen to nearly 36% of total energy consumption, while carbon dioxide emissions accounted for 28.3% of total emissions, and This percentage is still rising steadily. In China, my country's building energy consumption is second only to industrial production energy consumption. With the introduction of the concepts of building energy-saving systems such as passive houses and zero-emission buildings, it shows that bo...
