Embodiment Construction

[0012] The present invention is further described below in conjunction with specific embodiments, but does not constitute any limitation to the protection scope of the present invention.

[0013] The phase change temperature and the phase change enthalpy of the microcapsule phase change material mentioned in the present invention are measured and can adopt differential scanning calorimeter (DSC), at N 2 Under protection, the heating rate is 5°C / min, and the measurement temperature range is -40°C to 200°C. The measured temperature corresponding to the peak top of the main absorption peak is the phase transition temperature. Between the start temperature and the end temperature of the peak, the absorption The heat corresponding to the area enclosed by the heat peak and the baseline is the phase change enthalpy. Its curve is shown in Figure 1.

[0014] Raw material ratio: 60 mesh wood powder 55wt%, high-density polyethylene (HDPE) 35wt%, compatibilizer 4.0wt%, conventional lubri...

Abstract

The invention relates to the making of wide breath hard wood. It mixes wood, fiber and thermal plastic material to be pressed by special mold press equipment to get hard wood with width reaching 1220mm, thickness 6-50mm.It can be used for the decoration board, hanging board and floor, being automatically adjusting temperature and reducing energy. It can resist water, corrosion, aging like natural wood. It can be sawed, cut, drilled like real wood, with good mechanical feature.

Description

technical field [0001] The invention relates to a production method of phase-change heat storage and temperature-regulating polymer wood boards, specifically, a polymer wood board with the ability to regulate indoor temperature within a certain range obtained by blending phase-change energy storage materials and wood polymer composite materials. wooden planks. Background technique [0002] During the phase change process, phase change materials can absorb heat (cold) from the environment or release heat to the environment, so as to achieve the purpose of energy storage and release and the matching of energy demand and supply. Solid-liquid phase change materials will expand or contract when the system changes, and leaks will occur when the material melts, so phase change materials need to be shaped when they are applied. Microcapsule encapsulation technology is a better method: the carrier matrix is ​​made into microcapsules according to a certain process, and then the solid...
