Embodiment 1

[0027] The present embodiment provides a process method for preparing a recycled floor from scrap materials, which is performed in sequence as follows:

[0028] S1. Preparation of recycled floor blanks: Collect the wood scraps and pulverize them into flakes with a size of 2-3mm and a thickness of 0.3-0.5mm. Preheat the flakes at a temperature of 20°C for 30min; 35°C for 2h. After preheating, it is mixed with melamine modified urea-formaldehyde resin glue, so that the flake fragments are completely wrapped by glue, and then placed in the mold, the press is started, the upper mold and the lower mold of the mold are closed, and the cold pressing is solidified into a plate. During cold pressing, the pressure was slowly increased for 20 minutes until the pressure reached 0.1Mpa, and then the pressure was maintained for 30 minutes. Take out the floor blank after cold pressing, and coat the upper surface with a transparent acrylic resin layer to obtain a recycled floor blank with a ...

Embodiment 2

[0033] The present embodiment provides a process method for preparing a recycled floor from scrap materials, which is performed in sequence as follows:

[0034] S1. Preparation of recycled floor blanks: Collect the wood scraps, pulverize them into flakes with a size of 4-6mm and a thickness of 0.3-0.5mm, and preheat the flakes at a temperature of 20-30°C for 40min; The temperature was raised to 35°C and maintained for 3h. After preheating, it is mixed with melamine-modified urea-formaldehyde resin glue, so that the flakes are completely covered with glue, and then placed in the mold, the press is started, the upper and lower molds of the mold are closed, and the cold-pressed solidification becomes a plate. During cold pressing, slowly increase the pressure for 20 minutes until the pressure reaches 0.15Mpa, and then maintain the pressure for 100 minutes. Take out the floor blank after cold pressing, and coat the upper surface with a transparent acrylic resin layer to obtain a ...

Embodiment 3

[0039] The present embodiment provides a process method for preparing a recycled floor from scrap materials, which is performed in sequence as follows:

[0040] S1. Preparation of recycled floor blanks: Collect the wood scraps, pulverize them into flakes with a size of 4-6mm and a thickness of 0.3-0.5mm, and preheat the flakes at a temperature of 30°C for 60min; 40°C for 2.5h. After preheating, it is mixed with melamine modified urea-formaldehyde resin glue, so that the flake fragments are completely wrapped by glue, and then placed in the mold, the press is started, the upper mold and the lower mold of the mold are closed, and the cold pressing is solidified into a plate. During cold pressing, the pressure was slowly increased for 25 minutes until the pressure reached 0.2Mpa, and then the pressure was maintained for 150 minutes. Take out the floor blank after cold pressing, and coat the upper surface with a transparent acrylic resin layer to obtain a recycled floor blank wit...

Abstract

The invention relates to a regenerated floor prepared from waste wood. The regenerated floor is prepared by the following steps: collecting wood leftover materials, crushing the wood leftover materials into fragments, carrying out preheating treatment, mixing and stirring the fragments with a colloidal solution, and carrying out cold pressing and solidification to form a board; wood is cut and subjected to vacuum drying treatment to control the water content, and a floor base layer blank is manufactured; and the single face of the floor base layer blank is coated with cold pressing glue, then the regenerated floor blank is attached to the floor base layer blank, cold pressing treatment is conducted, and the finished regenerated floor is manufactured. The waste wood leftover materials are recollected and processed to prepare the floor with certain strength and high wear resistance, so that waste recycling is realized, wood resources are effectively saved, and the problem of environmental pollution is solved while the problem of resource waste is solved.

Description

technical field [0001] The invention belongs to the technical field of home building materials, in particular to a recycled floor prepared by using waste wood. Background technique [0002] Wooden floor is a floor decoration material formed by drying and processing of natural wood. It is a floor directly processed from solid wood. It has the texture of natural growth of wood and is a poor conductor of heat. It can play the role of warm in winter and cool in summer. It is comfortable and safe to use. However, the cost of wooden floors is high, and the use of non-renewable trees in a short period of time is not conducive to environmental protection. However, during the processing of wooden floors, a large amount of waste is generated and resources are wasted. [0003] In the prior art, there is also the preparation of recycled floors by crushing the waste materials, but the granular wood fragments or irregular wood fragments such as wood chips are difficult to mix evenly when...
