Abstract

A continuous-fiber reinforced thermoplastic polymer temperature-adjusting plate comprises a surface plate, a bottom plate, a honeycomb core layer and a phase-change energy-storage material packed in the honeycomb core layer. The surface plate, the bottom plate and the honeycomb core layer are prepared from a sheet of a continuous-fiber reinforced thermoplastic polymer composite material filled with a modified heat-conduction filler, the honeycomb-core-layer phase-change energy-storage material is packed in multiple mutually-independent chambers in the honeycomb core layer, and the surface plate and the bottom plate are respectively combined with the upper surface and the lower surface of the honeycomb core layer through heat fusion. By blending a high-heat-conductivity substance with the polymer, the high-heat-conductivity continuous-fiber reinforced thermoplastic polymer plate, which is prepared by employing a double-face film coating method, has high specific modulus and specific strength. The honeycomb core layer employs a material same to that of the surface plate, and the honeycomb core layer and the surface plate are firmly bonded through fusion. Honeycomb holes are filled with the phase-change material, the addition amount is large and the problem that the phase-change material precipitates is effectively avoided. The continuous-fiber reinforced thermoplastic polymer temperature-adjusting plate has an expanded application field and is especially applicable to decoration of indoor decoration furred ceilings and wall surfaces.

Description

Technical field [0001] The invention relates to a building or decoration board with constant temperature, energy storage and automatic temperature adjustment functions. Specifically disclosed is a continuous fiber reinforced thermoplastic polymer temperature regulating board. Background technique [0002] Building a resource-saving and environment-friendly society is the guiding principle for the development of the country today. In the engineering field, phase change plates with self-adjustable temperature are used, which can not only maintain indoor temperature, but also reduce greenhouse gas emissions and achieve the purpose of energy saving and emission reduction. However, the existing phase change energy storage plates use metal plates to sandwich the microcapsule phase change material, which has key problems such as easy leakage, easy flow, and poor decorative effect during cutting. [0003] Generally, phase change materials are prepared by blending modification methods, th...
