Problems solved by technology

[0002] Veneer panel is also called decorative veneer veneer plywood. It is a decorative panel with single-sided decorative effect made by precision-slicing solid wood into thin veneer, using plywood as the base material, and gluing process. Cabinets are also often used on wooden floors, but the bonding strength of the existing veneers on the surface of wooden floors is poor, which is not conducive to the long-term use of wooden floors

Abstract

The invention discloses a preparation method of a veneer for wood flooring, which comprises the following steps: (1) sorting the substrate and the panel; (2) configuring an adhesive: the adhesive includes the following raw materials in parts by weight: urea-formaldehyde resin: 90-95 parts; polyvinyl acetate: 15-20 parts; titanate coupling agent: 1-2 parts; chlorinated olefins: 0.5-1 parts; retarder: 0.1-0.5 parts; curing agent: 0.5-1 parts; Agent: 10-15 parts; mix and stir the above raw materials until the glue is a paste-like viscous liquid, and it is obtained; (3) glue coating; (4) veneer; (5) pressing; (6) trimming and sawing; Surface finishing of the pressed planks and edge sawing to the required specifications, vested. The wood floor veneer prepared by the method has strong bonding strength, which ensures that no edge warping occurs during use.

Description

Technical field [0001] The present invention relates to the technical field of home decoration, in particular a wooden floor of plywood preparation method. Background technique [0002] Also known as decorative plywood veneer plywood, wood precision is sliced ​​into thin veneer, plywood for the substrate, the process is made after adhesive decorative sheet having a decorative effect one surface of the sheet except the door cabinet, is also often applied to the wood, but wood veneer bonding strength of the existing floor surface is poor, is not conducive to long-term use of wood flooring. Inventive content [0003] The present invention aims to solve at least one of the prior art present technical problems that end, the present invention provides a method for preparing plywood flooring and wood flooring prepared by the method has a strong bonding strength with plywood. [0004] According to an aspect of the present invention, there is provided a method for preparing wood veneer, ...
