Elevator heat preservation and sound insulation decorative sheet

Abstract

The invention discloses an elevator heat preservation and sound insulation decorative sheet. The elevator heat preservation and sound insulation decorative sheet comprises a clamping plate layer, a fixing layer and a heat preservation layer. The heat preservation layer comprises multiple stages of heat insulation layers, and the multiple stages of the heat insulation layers are all formed by filling thermal insulation materials. Heat preservation separation plates are arranged between every two adjacent heat insulation layers. Grid plates are arranged in all the stages of the heat insulation layers and further divide all the stages of the heat insulation layers into a plurality of heat preservation areas. Heat preservation separation plates located between every two adjacent heat preservation areas are provided with heat conduction holes and stopping pieces which are movably embedded into the heat conduction holes. Driving parts used for driving the stopping pieces to be opened or for shielding the heat conduction holes are arranged between the stopping pieces and the heat preservation separation plates. The moving distance of the stopping pieces driven by the driving parts and the temperature variation amplitude in the heat preservation areas are set in a positive correlation mode. The multiple stages of the heat insulation layers are arranged and further divided into the multiple heat preservation areas which are conditionally connected, transmission efficiency of heat in the heat preservation layer is lowered through the heat preservation areas, heat transmission can be guided in a directional mode, the heat does not penetrate through the heat preservation layer to form a heat conduction access directly, and accordingly a good heat preservation effect can be achieved.

Description

Technical field [0001] The invention relates to the technical field of elevator decorative board manufacturing, and more specifically, it relates to an elevator thermal insulation and sound insulation decorative board. Background technique [0002] In the elevator car, in order to increase the aesthetics of the elevator car, decorative panels are often arranged on the inner wall of the elevator car. The decorative panels in the prior art only play a decorative role, and this province does not have the effect of heat preservation and heat insulation. Generally, thermal insulation materials such as thermal insulation foam boards are arranged in the car wall of the elevator car. The above setting method is relatively simple and rude, and does not have a specific purpose. For example, for some extremely cold or extremely hot areas, the above setting cannot effectively block the heat exchange between the elevator car interior and the elevator shaft, and the heat preservation effect i...
