Breathable wood-plastic plate production technology

[0029] Example

[0030] Such as Figure 1-Figure 4 As shown, the adhesive and plant fiber are mixed into an initial material, and the initial material is heated to 180°C; the heated initial material is processed into a flat substrate through plastic processing techniques such as extrusion, molding, and injection molding. The thickness of the substrate is 8mm, one side of the substrate is flat, and a solid wood board with a thickness of 2mm is glued on the flat surface. On the other side of the substrate, a rectangular array has a number of square installation grooves with a depth of 4mm. The distance between adjacent installation grooves on the substrate is 4mm, a card slot with a depth of 4mm is formed between every four adjacent installation slots; then take the heated initial material and pass it into a fixed column 3, an alignment column 101 and a platform column 201. The two ends of the fixed column 3 are formed There are ribs 301 matched with the slot, the alignment column 101 is tapered, the platform column 201 is frustum-shaped, the top surface of the platform column 201 is provided with an alignment hole 202 that matches the alignment column 101, the platform column The bottom surfaces of the 201 and the alignment column 101 are square, the fixed column 3 is hollow, the side wall of the fixed column 3 has through holes, and the fixed column 3 is filled with activated carbon particles; take a substrate as the lower plate and place it in the installation groove of the lower plate The upper alignment column 101 is internally bonded, and one end of the fixed column 3 is clamped in the slot of the lower board; the other substrate is taken as the upper board, and the upper support pillar 201 is bonded in the mounting groove of the upper board; in the alignment hole Add glue to 202, align the upper board with the lower board, and insert the alignment column 101 into the alignment hole 202, and the other end of the fixed column 3 is clamped into the slot on the upper board; the upper board and the lower board are aligned In the internal extrusion, the pressure of the upper and lower plates is 800 KPa, so that the supporting pillar 201 and the alignment pillar 101 are bonded together.

[0031] Since the alignment column 101 is tapered, the platform column 201 has a frustum shape, and the opposite ends of the alignment column 101 and the platform column 201 are connected with each other at their ends with a smaller cross section, so that the alignment column, the platform column 201 and the fixed column 3 A diamond-shaped gap 4 is formed. The gaps 4 communicate with each other, and these gaps 4 increase the air permeability of the wood-plastic board. When the harmful gas in the wood-plastic board escapes, part of it will enter the fixed column 3 and be absorbed by the activated carbon particles, and the other part of the harmful gas will enter these diamond-shaped gaps 4 and immediately radiate from the side of the wood-plastic board. To avoid the accumulation of harmful gases in the wood-plastic board, and to avoid long-term slow release of harmful gases and long-term pollution of the air.
