Composite phase change material composition for window frame

Abstract

The invention provides composite phase change material composition for a window frame. The composite phase change material composition is prepared from polyolefin, phthalate, a hydrocarbon mixture, acarbon material, a silicate material, a resin material and a polymer. The material composition can absorb or release a large amount of heat on the premise of unchanged size and unchanged performance in a phase change process, so that product performance stability is guaranteed, the problems about cold insulation and heat insulation of the window frame are solved, indoor temperature equalization ofa building is realized, indoor temperature fluctuation is reduced, start times of an air conditioner are reduced, energy consumption of the building is reduced remarkably, and energy using efficiencyis increased.

Description

Technical field [0001] The invention belongs to the technical field of phase change materials, and specifically relates to a window frame composite phase change material composition. Background technique [0002] Phase change material technology mainly uses its characteristics of providing latent heat while changing the phase under the conditions of a specific temperature region, absorbing or releasing a large amount of heat, so as to realize the application of a certain technology. According to its phase change range and characteristics, it can be widely used in different fields, such as aerospace (astronaut clothing, etc.), military fields (military vehicles, ships, aircraft, tanks, etc.), power communication fields (electric cabinets, etc.), Refrigeration equipment field (air conditioning, cold storage, etc.) and construction field (electric heating, etc.). [0003] At present, in the field of building door and window manufacturing in China, window frames have gradually transit...

AI Technical Summary

Problems solved by technology

The phase change will make its technical products change in volume, specifically: after the solid-liquid phase change, the product will seep out of liquid, or brittle cracks will occur, and the sealed product will expand, etc., which will affect the stability of product performance; -After the solid phase change, the flow channel of the product will be blocked, and the density and hardness of the product will change, which will also affect the stability of product performance; no matter which phase change method is used, it will have a significant impact on the service life of the product

In addition, in terms of product forming, due to the phase change characteristics, there are still some problems in the key issues of product forming. For example, the hot pressing method is used to form the material, and the pressing temperature is likely to exceed the phase change temperature of the phase change material itself. During the process, due to the leakage of the phase change material due to the solid-liquid phase change, the performance of the sheet is reduced, and at the same time, brittle cracks are prone to occur after forming, which affects the quality of industrialization
