A thermal insulation system and its material preparation method

Abstract

The invention relates to an insulation system and a preparation method of materials thereof, in particular to a heat insulation system and a preparation method of materials thereof, and belongs to the technical field of building materials. The heat insulation system comprises a bonding layer, an insulating layer, a dual-phrase-change layer, a strengthening protective layer, an elastic putty layer and a reflecting layer which are sequentially arranged from a wall to the outside. The insulating layer is one of an expanded polystyrene board, an extruded polystyrene board, a phenolic aldehyde board, a polyurethane board, a cement foaming insulation board and a rock wool board. The dual-phrase-change layer is made of dual-phrase-change shaping materials. The strengthening protective layer comprises anti-crack mortar and alkali-resisting gridding cloth. The reflecting layer is a reflecting insulating mold coating. The heat insulation system has the advantages that heat insulation efficiency can be improved, phrase change materials can play a role both in summer and in winter, and therefore energy-saving efficiency is improved.

[0002] With the development and progress of society, my country's energy consumption in the construction field is gradually increasing, and building energy conservation has become an important issue in today's society. The traditional thermal insulation system only uses low thermal conductivity materials to slow down the energy transfer rate, but does not It can completely absorb energy and fundamentally prevent energy transfer; because traditional thermal insulation systems can only slow down the rate of energy transfer, but cannot prevent energy transfer; traditional building phase change materials can only function in one season, and when When the surface temperature is too high, the phase change material will melt in a short period of time, which is not conducive to long-term energy storage

Phase change material is a new type of heat storage material, which can absorb and release a large amount of heat when the phase transition occurs, while keeping the temperature relatively stable. A Chinese invention patent application titled "Low Melting Point Paraffin Microcapsules Phase Change Thermal Storage Mortar and Preparation Method" discloses a thermal insulation mortar based on a phase change thermal storage mechanism. The Chinese Invention Patent Application of A Thermal Insulation Phase Change Temperature Adjusting Coating” discloses the use of phase change materials in substrates such as mortar and paint. The disadvantage of the above two patent applications is that the amount of phase change materials added is less There is less heat, and the matrix has the problem of poor compatibility, and the phase change material can only play a role in one season; as the publication number is CN102977857A, a Chinese patent entitled "A Phase Change Energy Storage Microcapsule and Its Preparation Method" The invention patent application discloses the preparation method of phase-change energy storage microcapsules. The microcapsules are composed of two kinds of phase-change materials and two layers of capsule walls, which can enhance stability and alleviate thermal shock. However, the preparation method is complicated and difficult to produce.
