Improved production technology for mold-pressed wood part coated with melamine impregnated abrasion-resistant paper

Abstract

An improved production technology for a mold-pressed wood part coated with melamine impregnated abrasion-resistant paper is invented in order to optimize product performance. The improved production technology comprises the process that the surface of a to-be-coated layer of a mold-pressed wood part blank is clad with the melamine impregnated abrasion-resistant paper in a mold, and mold-closing, pressurizing and heating are conducted, so that the melamine impregnated abrasion-resistant paper is attached to the surface of the mold-pressed wood part blank and cured. The improved production technology is characterized in that the melamine impregnated abrasion-resistant paper which is gradually soft during low heat and is cured during high heat is adopted, in a mold press with the mold arranged in the mode of up-down mold opening and closing, the mold-pressed wood part blank is arranged in a lower mold cavity, the mold-pressed wood part blank is covered with the melamine impregnated abrasion-resistant paper which is gradually soft during the low heat and is cured during the high heat, the melamine impregnated abrasion-resistant paper which is gradually soft during the low heat and is cured during the high heat is baked and heated firstly till the melamine impregnated abrasion-resistant paper is softened, and then mold-closing, pressurizing and heating are conducted, so that the melamine impregnated abrasion-resistant paper which is gradually soft during the low heat and is cured during the high heat is attached to the upper surface of the mold-pressed wood part blank and cured.

Description

technical field [0001] The invention belongs to the technical field of molded wood production. In particular, the invention relates to a production process of covering a molded wood blank with melamine-impregnated wear-resistant paper. Background technique [0002] Molded wood parts are made of wood powder (mainly lignin and / or cellulose) with suitable particle size as filling material, thermosetting material as binder, and solidified in the mold under the action of pressure and heat. Wooden artifacts. Molded wood parts are widely used in furniture, construction, machinery and other fields, and can often obtain the effect of imitating logs. [0003] The existing production process of molded wood pieces is generally to mix wood powder and binder at room temperature to obtain molding materials, then fill the molded materials into molds, pressurize and heat, and obtain molded wood parts blanks. [0004] In order to optimize the mechanical and physical properties of the molde...

AI Technical Summary

Problems solved by technology

However, because the commercially available melamine-impregnated wear-resistant paper appears as brittle and easily broken sheets, limited by the production process of the coating, the current melamine-impregnated wear-resistant paper is only used for flat coatings, such as floors and furniture countertops.
