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. laminate flooring

specific Embodiment approach 1

[0019] Specific Embodiment 1: Combining figure 1 Description of this embodiment, a method for manufacturing lacquered wood-plastic composite flooring, including the following steps: S1, veneer preparation: use rotary cutting or planing to determine the thickness of the veneer; use sawing, cutting, cutting, planing Cutting, gluing, pressing or sewing one or a combination of several methods, fixed-width processing veneer; the thickness of the prepared veneer is 0.5mm-5mm, and the width is 80mm-200mm; S2, veneer sorting : Sorting the veneers according to their apparent quality. The veneers with beautiful surface, no decay, no blue stain, no moths, and no blemishes are selected as veneers. The outer surface; the rest of the veneers are used as the core board; S3, veneer treatment: firstly pretreat the sorted veneers, the pretreatment is one or more of drying treatment and high temperature heat treatment; then carry out Surface treatment, seven primers and two topcoats on the oute...

specific Embodiment approach 2

[0021] Specific Embodiment 2: Combining figure 1 Describe this embodiment, the manufacturing method of a lacquered wood-plastic composite floor described in this embodiment, in step S9, the two long sides and two short sides of the floor have grooves after milling, and the The two long side surfaces have corresponding grooves matching each other; the two short sides also have corresponding grooves matching each other; the others are the same as in Embodiment 1.

[0022] The technical effect of this embodiment is: through the use of the end milling machine and the double-end milling cooperating operation, the floor has grooves that can match each other, so that the floor products manufactured on the assembly line can be directly put into use, reducing manual intervention and processing errors. The production efficiency is improved; the grooves and grooves obtained have the characteristics of matching each other, and also ensure the matching and non-deformation in the thickness-...

specific Embodiment approach 3

[0023] Embodiment 3: Combining figure 1Describe this embodiment, the manufacturing method of a lacquered wood-plastic composite floor described in this embodiment, in step S3, through one or more methods in ventilated drying, high temperature heat treatment and plasma treatment, make the water content of the veneer lower than 5%, while reducing the surface energy of the veneer; the others are the same as in Embodiment 1.

[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 floor, reducing the possibility of air bubbles inside the floor 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 beneficial to improve the interface bonding strength between wood...

Abstract

The invention discloses a manufacturing method of a lacquered wood-plastic composite floor. In order to realize quickly manufacturing the lacquered wood-plastic composite floor and solve the problem that a conventional hot pressing method needs long-time pressure-maintenance cooling, the invention provides the manufacturing method of the lacquered wood-plastic composite floor. According to the manufacturing method, the floor is prepared through the steps of veneer preparation, veneer sorting, veneer treatment, coupling agent coating, plastic thin film preparation, superposition for blank assembly, heating and roll extrusion, fixed-thickness cooling and side surface milling. The manufacturing method has the beneficial effects that the continuous production of the wood-plastic composite floor is realized; the defects that a pressure-maintenance cooling process is time-consuming and energy-consuming are avoided; the production efficiency of a wooden composite floor is improved; meanwhile,the improvement of the mechanical performance and the surface quality of a product is facilitated; a wooden raw material and plastic which are inside the floor are uniformly distributed; the amelioration of the mechanical performance and the surface quality of the floor is facilitated; meanwhile, the wood-plastic composite floor including a lacquer coating is also molded once; the production period is shortened and the energy consumption is decreased.

Description

technical field [0001] The invention belongs to the field of composite materials, and relates to a method for preparing a composite floor, in particular to a method for manufacturing a lacquered wood-plastic composite floor. 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. Floors made of wood-plastic composite materials are accepted by consumers because of their good durability, good corrosion resistance, moderate price, environmental protection and low carbon. In the manufacture of wood-plastic compo...
