Exterior wall insulation decorative plate capable of adaptive temperature control and fire extinguishing without electricity

Abstract

The invention discloses an exterior wall insulation decorative plate capable of adaptive temperature control and fire extinguishing without electricity, and belongs to the building material fireproof warming plate technology field. The insulation decorative plate comprises a hollow aluminium section; more than one layer of aluminium foil heat conduction-insulation member in the enclosed space inside the hollow aluminium section; a novel bias current twist mode heat catcher arranged in an air flow adjusting layer of the exterior wall fireproof insulation decorative plate that can enhance the fluid's fluidity and bias current effect and improve heat catching effect by using a special physical structure of the heat catcher; a novel intelligent heat transition function paint, an inorganic foaming anticorrosion flame retardation layer; a low cost intelligent temperature-sensitive function assembly installed in the installation gap between the fireproof warming plate and the metope that can track temperature change and generate deformation automatically; and a fire extinguishing performer, namely an intelligent combination of a shape memory alloy temperature-sensitive performer and a shape memory temperature-sensitive fiber capsule. The insulation decorative plate has the advantages that excellent fireproof and moistureproof performances are provided; adaptive temperature adjustment and fire extinguishing are realized; and high mechanical strength, good toughness, light weight and low cost are provided.

Description

technical field [0001] The invention relates to a fire-proof and heat-preservation decorative board for an exterior wall, in particular to a heat-preservation decorative board for an exterior wall that can self-adjust and extinguish fire without using electricity, and belongs to the technical field of fire-proof and heat-preservation boards for building materials. The technical solution adopted by the present invention is not the same as the conventional method and technical route for improving the heat insulation and heat preservation technology of the fireproof heat preservation board and the method and technical route for adjusting the temperature of the outer wall. The thermal insulation ability does not rely on temperature sensors, actuators, and computer software and hardware to adjust and control the temperature of the external wall fire insulation board, but according to the laws of thermodynamics, especially the knowledge of Fourier's law of heat and Newton's law of co...

Problems solved by technology

This is a double-edged sword, which brings many side effects: it will lead to the overweight of the external wall fire insulation board, poor wind and snow resistance, short life and high cost

[0009] 2. Most of the fire-proof and thermal insulation panels for external walls in China are made of cement concrete and glass magnesium boards. They have strong heat absorption capacity and large heat capacity. They absorb a lot of heat during the day in summer and accumulate heat at night. The ground radiates out, resulting in overheating inside the wall. The temperature of the outer wall cannot be automatically controlled and adjusted according to the weather and ambient temperature. You cannot have both.

[0014] In our opinion, the above method is very effective, but its main disadvantages are high investment cost and operation cost, followed by complex maintenance technology, and also because it involves open-air use of power and electricity, as well as equipment maintenance problems and equipment aging, calibration and adjustment technologies , requires a special person to be responsible, and the failure rate is relatively high, so ordinary users cannot accept it.

[0015] According to intelligence tracking and user research, there is currently no manufacturer at home and abroad that uses an aluminum foil heat-conducting-insulation component with centrifugal glass wool inside to improve the isothermal characteristic curve, a bias current torsion heat collector with a gap, and an intelligent heat sink that does not use electricity. A report on the production of exterior wall fireproof and thermal insulation decorative panels with the cooperation of sensitive functional components and fire extinguishing actuators, new intelligent color heat conversion functional coating layers, inorganic foaming anti-corrosion and fire-resistant coating layers, etc.
