Phase-transition self-temperature-regulating heat-preserving facing brick of external wall and manufacturing method thereof

Abstract

The invention relates to a phase-transition self-temperature-regulating heat-preserving facing brick of an external wall, which is an integrated structure compacted by a phase-transition heat-preserving layer and an inorganic facing layer, wherein the phase-transition heat-preserving layer is mixed by proportion and compacted by hull-type expanded perlite heat-preserving aggregates, phase-transition temperature-regulating aggregates and cements; the inorganic facing layer is mixed by quartz sand, calcium carbonate, calcium oxide, cement and silicon oxide powders; and the phase-transition temperature-regulating aggregate is made of phase-transition cores and encapsulated hulls. The manufacturing method not only effectively solves the encapsulation problem of the phase-transition material, leads the prepared phase-transition self-temperature-regulating heat-preserving facing brick of the external wall to have excellent heat-preserving performance, waterproof performance and permanent anti-ageing performance, but also radically solves the obsolescence of thermo-physical property and the leakage problem of phase-transition material in the circulation process. The facing brick has the advantages of light weight, strong adhesion strength, large compressive strength, heat insulation, heat preservation, waterproof and moisture-proof performances, obvious energy-saving effect, and the like.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for building walls, and relates to a phase-change self-regulating exterior wall thermal insulation facing brick and a manufacturing method thereof. Background technique [0002] With the continuous development of science and technology, people have put forward higher requirements for the energy-saving effect of building insulation walls. In addition, modern buildings are developing to high-rise buildings, and the envelope structures used are required to be lightweight materials. In the prior art, the commonly used external wall composite thermal insulation method is to coat or paste a polystyrene thermal insulation layer on the external wall of the wall, add steel wire mesh, thermal insulation nails, then make a reinforcement layer and an anti-crack layer, and finally make For the finish layer, this method not only has complicated process, long construction period and high cos...

AI Technical Summary

Problems solved by technology

However, in the production of composite phase change insulation layers, traditional phase change materials usually adopt bone glue-based packaging technology. Due to the lack of sealing, poor film-forming performance, low strength, and easy melting at slightly higher temperatures, it is easy Leakage, poor working stability, loss of temperature adjustment performance, failure to reach a closed state and many other defects seriously affect the use effect and service life of phase change materials

So far, there is no external wall insulation brick with self-regulating temperature function made of phase change materials on the market. The main reason is that the packaging technology has not been ideally solved, which restricts the application of phase change materials in the construction field. Promote application
