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 structure of wood-plastic panels is dense, and these harmful gases will stay in the wood-plastic panels for a long time and pass through. The tiny holes on the wood-plastic board are slowly released, and this process is very long

Embodiment

[0030] Such as Figure 1-Figure 4 As shown, the adhesive and plant fiber are mixed into a primary material, and the primary material is heated to 180°C; the heated primary material is processed into a flat substrate by extrusion, molding, injection molding and other plastic processing techniques. The thickness of the substrate is 8mm. One side of the substrate is a plane, and a solid wood board with a thickness of 2mm is glued on the plane. There are several square installation grooves with a depth of 4mm in a rectangular array on the other side of the substrate. The distance between adjacent installation grooves on the substrate is 4mm, every four adjacent installation grooves are formed with a depth of 4mm slots; take the heated primary material to make the fixed column 3, the alignment column 101 and the platform column 201, and the two ends of the fixed column 3 are formed There is a rib 301 matched with the card slot, the alignment column 101 is conical, the cap column 20...

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.

Description

technical field [0001] The invention relates to the field of building material production technology. Background technique [0002] Wood-plastic composites (Wood-Plastic Composites, WPC) is a new type of composite material that has been booming at home and abroad in recent years. Wooden materials are processed by extrusion, molding, injection molding and other plastic processing techniques to produce panels or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. Plastic and wood powder are mixed in a certain proportion and then hot-extruded to form a board, which is called an extruded wood-plastic board. [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 structure of wood-plastic panels is dense, and these harmful gases will stay in the wood-plastic panels for ...
