Problems solved by technology

However, the microcapsules prepared by this method choose urea and formaldehyde as the capsule wall material, which is easy to cause pollution during the production process and use process, and is not conducive to environmental protection and safety.
In addition, choosing to add a coupling agent to improve the compatibility of paraffin microcapsules and inorganic gel materials, the effect is not obvious

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a crack-resistant thermal insulation mortar. Background technique [0002] Insulation mortar is a kind of pre-mixed dry powder mortar made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed by the production enterprise. It is mainly used for building exterior wall insulation, and has the advantages of convenient construction and good durability. [0003] Heat storage technology can be used to solve the contradiction between thermal energy supply and demand mismatch, and is an important technology to improve energy utilization efficiency and protect the environment. There are three main storage methods: sensible heat, latent heat and chemical reaction heat. Among them, the latent heat method uses phase change materials to absorb heat (cold) from the environment or release heat (cold) to the environment during the ph...
