Abstract

The invention discloses a production process of a formaldehyde-free flame-retardant board, which comprises the following steps: (1) preparing a flame-retardant liquid; (2) soaking the base material of a formaldehyde-free multi-layer solid wood board in the flame-retardant liquid, pressurizing and soaking Finally, dry the base material soaked in the flame retardant solution; (3) The dried base material is combined with the use of formaldehyde-free glue, and after passing through the double-axis gluing machine, the front and back sides of the base material are evenly coated with formaldehyde-free glue. Glue; (4) Push the substrate plate at the front end of the gluing machine for gluing, then connect the rubber plate and lay the PP film at the back end of the gluing machine, then lay the bottom PP film, and then lay the rubber plate flat to the stacking and lifting (5) Place the laid PP film formaldehyde-free plate on the cold press for pre-pressing; (6) After the pre-pressing is completed, move the plate to the hot press for hot pressing ; (7) Saw the edge of the plate after the hot pressing. The formaldehyde-free multi-layer solid wood board of the present invention has good flame retardancy and mechanical properties, and can be widely applied.

Description

technical field [0001] The invention belongs to the technical field of plate processing, and in particular relates to a production process of a formaldehyde-free flame-retardant plate. Background technique [0002] Wood flooring is a commonly used ground decoration material. The main varieties include laminate flooring, solid wood composite flooring, solid wood flooring, and impregnated paper laminate veneer multi-layer solid wood composite flooring. Compared with other ground decoration materials such as carpet, stone, ceramic tile, and plastic floor, wooden floor has natural and beautiful texture, light weight and easy processing, good heat preservation, can adjust indoor temperature and humidity, and has the characteristics of being elastic and shock-relieving. It gives people a feeling of returning to nature, so it is loved by people and is widely used in the decoration of paving materials in indoor public places such as movie theaters and shopping malls. However, the ex...
