Problems solved by technology

[0005] Although traditional expanded perlite thermal insulation mortar has excellent thermal insulation performance, the porous characteristics of expanded perlite have been ignored, and phase change materials have not been immersed in the existing technology In the pores of expanded perlite, the paraffin / expanded perlite shaped phase change material was made, and the phase change material was used as fine aggregate to prepare phase change mortar specimens

Abstract

The invention discloses paraffin / expanded perlite phase-change thermal insulation mortar prepared from the following raw materials: 364 parts of ordinary Portland cement, 40 parts of coal ash, 160-200 parts of expanded perlite, 400-450 parts of water, 20-40 parts of epoxy resin, 20-40 parts of T31 curing agent and 320-400 parts of phase-change thermal energy storage material. The paraffin / expanded perlite phase-change thermal insulation mortar is prepared by two steps of firstly, preparing a paraffin / expanded perlite sizing phase-change material, and packaging the paraffin / expanded perlite sizing phase-change material; secondly, preparing the paraffin / expanded perlite phase-change thermal insulation mortar. The phase-change thermal insulation mortar can be used for effectively reducing the indoor temperature fluctuation range, shortening the indoor temperature fluctuation time and improving the living comfort level.

Description

[0001] Technical field: [0002] The invention relates to a preparation method of paraffin / expanded perlite phase-change mortar, which belongs to the technical field of application of phase-change energy storage materials and novel building thermal insulation materials. Background technique: [0003] Energy and environmental issues are two major issues that the world needs to face. Developing and utilizing renewable energy, changing the energy structure, reducing excessive emissions of greenhouse gases, and protecting the environment on which human beings live have become important components of the energy sustainable development strategy. part. [0004] Phase change material (PCM) can store energy in the form of latent heat of phase change in its body, and can change the phase state of matter in a specific temperature range to absorb or release a large amount of latent heat of phase change, which can be used for heat storage or cold storage. Since the phase change proce...
