Abstract

The invention belongs to the technical field of wood-based panel manufacturing, in particular to a surface control process for PB cold-laminated panels, which solves the problem that in the prior art, the veneering treatment of PB panels has high requirements on process parameters, and the veneered PB panels produced are subject to the level of production technology. Restriction, problems such as glue opening, blistering, and low bonding strength are prone to occur. The surface control process of the PB cold veneer, the PB cold veneer, in the order from top to bottom, is composed of composite veneer-plain board-composite veneer The surfaces are connected by the adhesive I, and finally cold-pressed and formed after post-processing. In the present invention, the composite veneer, the plain board and the adhesive I are prepared, and the composite veneer-plain board-composite veneer is connected by the adhesive I, and finally the PB cold veneer is prepared by cold pressing; the preparation method of the invention is simple, and cold pressing is adopted. The molding and cold-pressing solidification process has low requirements on process parameters, simple production operation, low preparation cost, and is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of wood-based panel manufacturing, in particular to a surface control process of a PB cold-laminated panel. Background technique [0002] PB board refers to the use of broken wood or broken wood fiber as the main raw material, the main raw material is cut into pieces of a certain size, after drying, mixed with rubber, hardener, waterproofing agent, etc., and pressed under a certain temperature and pressure. Wood-based board, also known as particle board, particle board, particle board, particle board, bagasse board, etc. PB boards are mainly used in furniture and construction industries, as well as in the manufacture of trains and automobile carriages. [0003] China's PB board production has experienced a repeated process of rising in the 1980s, declining in the 1990s, and then rising again in 2000. After the PB board was abandoned by the market due to poor quality and other reasons, many PB board compani...
