Paint-free plate

Abstract

The invention discloses a paint-free plate. The paint-free plate comprises a solid wood core board, a layer of konfetti soaked by melamine resin glue adhesive is covered on the solid wood core board, the solid wood core board is composed of a plurality of wooden strips, the wooden strips are connected through glue adhesive blocks arranged on the head end and the tail end, a layer of density board is installed between the solid wood core board and the konfetti, and a fire-retardant layer is arranged on the surface of the confetti; a wearing layer is arranged between the fire-retardant layer and the confetti. By this way, the paint-free plate is strong in adhesive property, the usage amount of glue is greatly reduced, environmental protection performance is more excellent, the paint-free plate is not prone to swell and deform in a usage process, and the product usage stability is better.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a paint-free board. Background technique [0002] Most of the energy-saving panels in the existing construction field in my country are made by spraying thermal insulation slurry on the surface of the panels. This kind of thermal insulation slurry panels often have a single color tone and poor decorative effect, and the thermal insulation effect is related to the amount of slurry. If the amount of coating is large, not only the cost will increase, but also the surface elasticity of the board will also decrease; and because many building boards are installed outdoors, they are prone to cracking under the influence of external factors such as rain and snow. , Yellowing, making the color of the wall itself unsightly. [0003] Paint-free board is a new type of environmentally friendly decorative material. Paper with different colors or textures is soaked in melamine resin adhes...

AI Technical Summary

Problems solved by technology

[0004] The paint-free boards on the market today have the following problems: the paint-free board with the core laminated with MDF and melamine finish is not environmentally friendly, cannot hold nails repeatedly, and the internal stress is unbalanced, which leads to easy deformation; three-plywood In the market of paint-free boards that fit the base material of the board, it is generally easy to open the glue; the paint-free board with the board core plus the middle board and then pasted with melamine has high adhesion and strong stability, but it has extremely high requirements on the process
