Problems solved by technology

[0003] Due to the extensive use of adhesives in the production of wood-plastic panels, the adhesives contain phenolic substances, which are easy to volatilize and produce harmful gases such as formaldehyde. However, the struc...

Method used

Because the alignment column 101 is conical, the bearing platform column 201 is a truncated cone, and the alignment column 101 and the bearing platform column 201 are all connected to each other at the smaller end of the cross section, so that the positioning column, the bearing platform column 201 and the fixed column A rhombus-shaped gap 4 is formed between the 3. The gaps 4 communicate with each other, and these gaps 4 increase the air permeability of ...

Abstract

The invention relates to the field of building material production technologies, and discloses a breathable wood-plastic plate production technology. The production technology comprises the steps that 1, an adhesive and plant fiber are mixed to be primary materials, and the primary materials are heated to 150-200 DEG C; 2, the heated primary materials are machined through a machining technology to be a substrate, one face of the substrate is a plane, the other face of the substrate is provided with installation grooves, and clamping grooves are formed among the installation grooves correspondingly; 3, fixing columns, alignment columns and bearing columns are manufactured, the alignment columns are in a conical shape, the bearing columns are in a frustum shape, and the top faces of the bearing columns are provided with alignment holes matched with the alignment columns; 4, the alignment columns are stuck to the interiors of the installation grooves on a lower-layer plate, one ends of the fixing columns are clamped into the clamping grooves on the lower-layer plate, and the bearing columns are stuck to the interiors of the installation grooves on an upper-layer plate; 5, the upper-layer plate and the lower-layer plate are stuck together; and 6, the upper-layer plate and the lower-layer plate are extruded inwards, and the bearing columns and the alignment columns are stuck together. The wood-plastic plate production technology aims at producing wood-plastic plates with good breathability.

Example Embodiment

[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.
