Abstract

The invention discloses an impregnated film paper veneer blockboard free from formaldehyde release as well as a production process thereof. The blockboard comprises a board core, a middle board, a surface board and impregnated film paper; and the middle board, the surface board and the impregnated film paper adhere to the two surfaces of the board core sequentially and symmetrically. The production process comprises board core production and blockboard production, wherein the blockboard production comprises the processes of gluing, assembling, performing cold-press molding, hot-pressing, reliving pressure, performing putty filling maintenance, determining thickness and sanding, gluing and sticking the surface board, performing cold-press molding, hot-pressing, sanding, performing edge sawing and pressing to stick decorative film paper. The problem of formaldehyde pollution of the blockboard can be solved, and people's high demand on environmental protection life can be met.

Description

technical field [0001] The invention belongs to the technical field of blockboard processing, and in particular relates to a formaldehyde-free impregnated film paper-decorated blockboard and a production process thereof. Background technique [0002] Blockboard, commonly known as large core board, has excellent characteristics such as good screw holding force, not easy to burst during processing, high strength and not easy to break, firm quality, sound absorption, heat insulation, etc., and is widely used in architectural interior decoration, furniture production and other fields. Currently, the blockboards sold in the market are mainly produced with urea-formaldehyde resin glue, which will release formaldehyde which is harmful to the human body and the living environment. The country has mandatory standards for products sold, and their formaldehyde emission must meet the specified requirements. In order to meet the standard requirements, manufacturers use modified urea-for...
