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 laminated board for a wood floor. The preparation method comprises the following steps: (1) sorting a base board and a panel; (2) preparing an adhesive, wherein the adhesive is prepared from the following raw materials in parts by weight: 90-95 parts of urea-formaldehyde resin; 15-20 parts of polyvinyl acetate; 1-2 parts of a titanate coupling agent; 0.5-1 parts of chlorinated olefin; 0.1-0.5 parts of a retarding agent; 0.5-1 parts of a curing agent; 10-15 parts of a filling agent. The preparation method comprises the following steps: mixing and stirring the raw materials until the glue solution is pasty viscous liquid; (3) performing gluing; (4) performing veneering; (5) performing pressing; (6) performing trimming and edge sawing; and allowing the pressed wood board to be subjected to surface finishing, performing edge sawing according to the required specification to obtain the laminated board. The laminated board for the wood floorprepared through adoption of the method has high bonding strength, and it is guaranteed that the edge warping phenomenon does not occur in the using process.

Description

technical field [0001] The invention relates to the technical field of home decoration, in particular to a preparation method of a wood floor veneer. Background technique [0002] Veneer panel is also called decorative veneer veneer plywood.
