Description

Composite plate containing phase change energy storage material

technical field

The utility model relates to an energy-saving composite board (partition board or partition wall board) used in buildings and instruments, in particular to a phase-change energy-storage material composite board.

Background technique

Due to the soaring prices of basic raw materials such as metals, oil, and electricity, and the sharp increase in consumption, human society has to consider the issue of energy conservation in various fields, including the use of lightweight, energy-saving building partitions or lightweight composite energy-saving panels in the construction field. In the field of construction, the energy-saving building partitions or lightweight composite energy-saving panels that have been adopted now, such as partitions used in shelters or mobile houses, are usually filled with polyurethane or polyester between two layers of skeletons (supporting boards). Formed from ethylene foam boards, the skeleton of which is mainly steel plates, iron plates, aluminum plates, and glass-steel stools, which play a load-bearing role, and the lightweight mineral insulation materials such as polyurethane, polyethylene foam boards, or expanded perlite filled in the middle mainly play a role. The effect of heat preservation and weight reduction; the thermal conductivity of polyurethane or polyethylene foam board is very low (below 0.05), and it has good thermal resistance when used in shelters or mobile houses. However, polyurethane or polyethylene foam boards are light in weight (density <30KG/m3), and have a small heat storage coefficient. Therefore, polyurethane or polyethylene foam boards are used as partitions or lightweight composite energy-saving panels for the sandwich layer, which have poor thermal inertia, are significantly affected by external temperature fluctuations, and have unsatisfactory thermal insulation and energy-saving effects.

In order to overcome the above-mentioned shortcomings of poor thermal inertia and unsatisfactory thermal insulation and energy-saving effect of the separator or lightweight energy-saving composite panel, the Chinese utility model patent CN200968018Y provides a lightweight energy-saving composite panel containing phase change materials. The quality and energy-saving composite board includes an outer support plate and an inner support plate. In the cavity formed by the outer support plate and the inner support plate, a filling layer of phase change material is set; on the sides, or in the middle of the fill layer of lightweight insulation material. Phase Change Material (Phase Change Material, PCM) is a substance that uses the heat absorbed or released during its phase change process (melting or solidification) to store latent heat energy. The characteristics of high heat storage coefficient, as well as the characteristics that during the phase change process, the phase change material stores or releases energy and the temperature of the phase change material itself remains almost unchanged before the phase change is completed, so as to achieve the purpose of heat preservation and energy saving. It is filled in the cavity formed by the inner and outer support plates, so that the space temperature in the lightweight composite energy-saving panel containing phase change materials can be kept within a small fluctuation range, "warm in winter and cool in summer". Compared with the energy-saving building partitions or lightweight composite energy-saving panels used in the past, its temperature control and energy-saving effect is more obvious, and its weight is light and the price is low, so it has been widely used. However, the phase change material will leak when it is in the liquid phase. In order to prevent the leakage of the phase change material, the phase change material filled in the composite plate can only be particles and powders that can undergo solid-liquid phase change inside through special technology. 1. A bulk composite phase change material, the composite phase change material is always in a solid state macroscopically, but undergoes a solid-liquid phase transition on a mesoscopic or microscopic scale. The special technology mentioned is microcapsule technology, sol-gel technology, active carbon adsorption, polymer qualitative encapsulation and so on.

Although the above-mentioned patented products have been used for many years, there are still some shortcomings: 1. Since the phase-change materials filled in the above-mentioned light-weight and energy-saving composite panels containing phase-change materials can only be composite phase-change materials made by special technology, its It is highly restrictive and expensive; 2. Since the main features of the lightweight energy-saving composite board are light weight and energy saving, in order to meet its requirements, the board body of the inner and outer support boards requires light weight, and the composite board The phase change material is directly filled into the cavity formed by the inner and outer support plates, and its support strength is not high.
