Intelligent temperature regulating polyurethane energy-saving plate and manufacturing method thereof

Abstract

The invention relates to an intelligent temperature regulating polyurethane energy-saving plate, comprising two colour steel plates and a polyurethane composite board which is arranged between the two colour steel plates, is bonded with the colour steel plates and is doped with organic energy storage phase change material and nano processing aid, wherein the organic energy storage phase change material accounts for 5-20% of the weight of the polyurethane composite board, and the nano processing aid accounts for 0.5-2% of the weight of the polyurethane composite board. The intelligent temperature regulating polyurethane energy-saving plate contains the energy storage phase change material and has good temperature regulating and heat insulating effects, when ambient temperature is higher than a set temperature, the energy storage phase change material absorbs heat and prevents the temperature from rising, and when the ambient temperature is lower than the set temperature, the energy storage phase change material releases heat and prevents the temperature from decreasing, thus intelligent temperature regulation is realized by virtue of the effect of the energy storage phase change material. Besides, the invention also relates to a manufacturing method of the intelligent temperature regulating polyurethane energy-saving plate.

Description

【Technical field】 [0001] The invention relates to the field of energy-saving materials, in particular to an intelligent temperature-regulating polyurethane energy-saving board and a preparation method thereof. 【Background technique】 [0002] Color steel composite board is an economical and practical building material developed in recent years. It is made of heat insulation composite maintenance by combining color coated steel plate or other panels and bottom boards with heat insulation core materials through adhesives or foaming agents. sheet. Color steel composite panels are mainly used in occasions that have special requirements for thermal insulation, such as: industrial plants, warehouses, cold storage, box packaging, light steel residences, original building mezzanine rooms, movable board rooms, various clean rooms, air conditioners room etc. [0003] Although the color steel composite board has a certain heat insulation performance, it is usually used in combination ...

AI Technical Summary

Problems solved by technology

[0003] Although the color steel composite board has a certain heat insulation performance, it is usually used in combination with the color steel composite board and high-grade polyurethane composite board, and the thermal conductivity of high-grade polyurethane composite board can reach 0.024W / (m*k), Under the action of sunlight (about 70°C on the outer surface), it is still easy to transmit a large amount of heat. Therefore, houses assembled with color steel composite panels cannot really achieve heat insulation in hot weather, and cannot achieve temperature adjustment functions.
