Problems solved by technology
Chinese patent application 200710055329.8 provides a kind of honeycomb concrete, which can solve the problem that the current building materials such as brick or concrete cannot meet the needs of light weight, energy saving and environmental protection in buildings
However, there are certain problems in this invention: one is that the composition of the honeycomb agent used is complicated, which is not conducive to the quality control of the honeycomb concrete material; Density less than 200kg / m 3 The third is that its thermal conductivity is relatively large. By measuring its embodiment, the thermal conductivity is greater than 0.08W / (m.K)
The problem of economy is that the addition of phase change materials increases the construction process and project budget, so that it loses its competitiveness with traditional materials

Abstract
The invention belongs to the technical field of building materials, and particularly relates to a light phase-change cellular concrete plate and a preparing method thereof. The concrete plate is prepared from cement, coal ash, phase-change materials, a foaming agent, a water reducing agent, an accelerator, fibers and water. The light phase-change cellular concrete plate is high in strength, small in dead weight and good in closed porosity.
Description
technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a phase change material, a lightweight phase change honeycomb concrete panel and a preparation method thereof. Background technique [0002] In recent years, frequent building fires have put forward higher requirements for the fire performance of thermal insulation materials. Inorganic thermal insulation materials have attracted widespread attention because of their advantages such as good fire resistance, aging resistance, small deformation coefficient, closeness to the wall, and high bonding strength with the wall. Research and develop honeycomb concrete panels with thermal conductivity less than 0.05W / m.k and lower cost to replace polystyrene panels and extruded panels, so as to solve the shortcomings of existing insulation panels such as easy aging, poor stability, poor durability, and low bonding strength with the wall It has become a direction of res...
