Embodiment Construction
[0020] 1. Use wood scraps to produce wood powder, add polyvinyl chloride particles, external additives, and fireproofing additives, and use high-temperature and high-pressure processes to form one-time molding such as figure 1 The wood-plastic hollow profile shown; its specifications are: the overall thickness is 40mm, the cross-sectional size of the hollow cavity ② is 20х40, the thickness of the plate rib ⑤ between adjacent hollow cavities is 20mm; there are joints on both sides ③; high temperature and high pressure The process is a well-known technology in the field, so it will not be described in detail; adding polyvinyl chloride particles, external admixtures, and fireproof additives to the wood powder can be adjusted by those skilled in the art according to needs.
[0021] 2. Soak the expanded perlite with a reasonable particle size distribution in fresh water for 24 hours, then wash it with clean water, dry it, and perform high-temperature roasting and activation at 700°C...

Abstract
The invention discloses a phase-change particle filled wood-plastic composite floor, and belongs to the technical field of composite floors. The phase-change particle filled wood-plastic composite floor comprises a wood-plastic hollow sectional material, wherein multiple cavities running through the two ends of a base body are formed in the base body of the wood-plastic hollow sectional material; each cavity is filled with a phase-change expanded perlite particle material. The floor overcomes various defects of traditional floors; the phase-change material inside the floor can absorb excessive heat energy at 25 DEG C in the day time for phase change, and then carries out phase change again to release heat energy when the temperature at night drops, so that intelligent adjustment for an indoor heat environment is realized. Meanwhile, as the floor sectional material has a hollow part, relatively good elasticity still can be realized without paving keels, and the walking comfort level is high. At the same time, the paving technology of the phase-change particle filled wood-plastic composite floor is completely as same as that of the common composite floor, so that the construction is convenient, and 100% floor can be recycled and reused.
Description
technical field [0001] The invention relates to a composite floor, in particular to a wood-plastic composite floor filled with phase-change particles and a preparation method thereof. It is mainly used for ground decoration projects of construction projects. Background technique [0002] At present, in building energy-saving projects, cement mortar, extruded polystyrene board (ρ=25-32), and reinforced concrete floor slabs are generally used for the floor of the building. Traditional architectural engineering drawings do not even have thermal insulation layers, and it is basically impossible to achieve floor temperature. Control, to a certain extent, affects the energy-saving effect of building floor engineering. When floor heating is used, heat is easily lost through the floor, resulting in a large loss of heat energy, resulting in energy waste and reducing indoor thermal comfort. However, the use of traditional solid wood flooring will cause consumption of wood, and the us...
