Problems solved by technology

[0004] However, the manufacturing efficiency of this technical scheme is low, and it cannot solve the problem that the traditional hot pressing method needs to maintain pressure for a long time and cool down
Not only is time wasted, but the temperature of the mold needs to be raised or lowered repeatedly during the pressure-holding and cooling process, which also wastes energy
Moreover, this technology cannot fundamentally solve the uneven distribution of wood and plastic inside the board, and the defects caused by the relative concentration of stress due to the uneven inside of the board to the mechanical properties and surface quality of the board, so high-quality wood-plastic products cannot be obtained. composite door

specific Embodiment approach 1

[0019] Specific Embodiment 1: Combining figure 1 Description of this embodiment, a method for manufacturing a wood veneer-plastic composite door panel, comprising the following steps: S1, veneer preparation: process the veneer with thickness by rotary cutting or planing; sawing, cutting, cutting, Planing, gluing, pressing or sewing one or a combination of methods, fixed width processing veneer; S2, veneer pretreatment: pretreatment of the prepared veneer, the pretreatment is drying One or more of treatment and high-temperature heat treatment; S3, Coating coupling agent: Coating a liquid coupling agent on the surface of the pretreated veneer, the liquid coupling agent is an isocyanate coupling agent, the amount It is 10g~80g per square meter; S4, preparation of plastic film: prepare thermoplastic film with the combination of thermoplastic new material, reclaimed material or new material and reclaimed material; The veneer of the joint agent and the plastic film prepared by step...

specific Embodiment approach 2

[0021] Specific Embodiment 2: Combining figure 1 Describe this embodiment, the manufacturing method of a kind of wood veneer-plastic composite door panel described in this embodiment, the thickness of veneer obtained in step S1 is 0.5mm~5mm, and width is 350mm~800mm; The thickness of the film is 0.1mm~1mm, and the width is 400mm~1000mm. ; Others are identical with specific embodiment 1.

[0022] The technical effect of this embodiment is: the above-mentioned limitation on the thickness and width of the film is conducive to reducing the amount of plastic film used, which can increase the strength of the door panel while reducing the weight of the door panel, and improve the strength-to-weight ratio of the door panel. Application prospects.

specific Embodiment approach 3

[0023] Embodiment 3: Combining figure 1 Describe this embodiment mode, a wood veneer-plastic composite door panel manufacturing method described in this embodiment mode, in step S2, through one or more methods of ventilation drying, high temperature heat treatment and plasma treatment, so that the content of the veneer The amount of water is less than 5%, and the surface energy of the veneer is reduced simultaneously; the others are the same as those in Embodiment 1 or 2.

[0024] The technical effect of this embodiment is: after the veneer is treated, the water content is controlled, and the surface energy is reduced, which is beneficial to the compounding of the veneer and the plastic film, and also improves the mechanical properties of the door panel, reducing the possibility of air bubbles inside the door panel. Smaller, avoiding the stress concentration caused by the appearance of air bubbles; at the same time, because the surface energy of the veneer is reduced, it is be...

Abstract

The invention discloses a manufacturing method of a wood veneer-plastic composite door panel. In order to realize quickly manufacturing the wood veneer-plastic composite door panel and solve the problem that a conventional hot pressing method needs long-time pressure-maintenance cooling, the invention provides the manufacturing method of the wood veneer-plastic composite door panel. According to the manufacturing method, the door panel is prepared through the steps of veneer preparation, veneer pretreatment, coupling agent coating, plastic thin film preparation, superposition for blank assembly, heating and roll extrusion, fixed-thickness cooling and edge decoration. The manufacturing method has the beneficial effects that the continuous production of the wood-plastic composite door panelis realized through carrying out hierarchical pavement on a veneer and a plastic thin film; through carrying out quick cooling molding on the door panel, the defects that a pressure-maintenance cooling process is time-consuming and energy-consuming are avoided; the production efficiency of a wooden composite door panel is improved; meanwhile, the improvement of the mechanical performance and the surface quality of a product is facilitated; in addition; a wooden raw material and plastic which are inside the door panel are also uniformly distributed and the amelioration of the mechanical performance and the surface quality of the door panel is facilitated.

Description

technical field [0001] The invention belongs to the field of composite materials, and relates to a method for preparing a composite door panel, in particular to a method for manufacturing a wood veneer-plastic composite door panel. Background technique [0002] Wood-plastic composites are one of the fastest growing new polymer composites in the field of composites. Extrusion, injection and hot pressing are the three main methods of producing wood-plastic composites. Wood-plastic composite panels are used in the construction industry and furniture manufacturing industry. The wood-plastic composite panels with superior performance can replace natural wood to manufacture wood-structured buildings, interior decoration parts, desks, cabinet furniture, etc. The door panels made of wood-plastic composite materials have the characteristics of water resistance and anti-change, good durability, good corrosion resistance, moderate price, environmental protection and low carbon, and ar...
