Flame-retardant adhesive for surface of artificial board as well as preparation method and application thereof

Abstract

The invention belongs to the field of wood decorative material manufacturing, and discloses a flame-retardant adhesive for the surface of an artificial board as well as a preparation method and application of the flame-retardant adhesive, and the flame-retardant adhesive is prepared by uniformly mixing 100 parts by weight of melamine formaldehyde resin, 50-100 parts by weight of a flame retardant,0-0.2 part by weight of a cellulose thickener and 5-10 parts by weight of urea, and coating the surface of the artificial board with the obtained flame-retardant adhesive for the surface of the artificial board to prepare the surface flame-retardant artificial board with visual wood grain texture. The flame-retardant adhesive which can be coated on the surface of the artificial board only throughsimple mixing is prepared by changing the resin adhesive and the auxiliary materials which are matched with the flame retardant for use, and a transparent flame-retardant adhesive layer can be formedon the surface of the artificial board after the flame-retardant adhesive is coated, so that the wood grain texture visualization effect of the artificial board is achieved; a decorative surface doesnot need to be pasted to cover the flame-retardant layer, and the fire-resistant grade reaches B1 (B) grade or B1 (C) grade.

Description

technical field [0001] The invention belongs to the field of wood decoration materials, and relates to a flame-retardant adhesive, in particular to a flame-retardant adhesive used on the surface of wood-based panels, a preparation method and application thereof. Background technique [0002] The mandatory standard of "Flame Retardant Products and Components Combustion Performance Requirements and Labels in Public Places" (GB20286-2006) stipulates that products and components entering public places must have a certain level of flame retardant performance. Wood products used in household and public places are flammable materials, and there are great fire safety hazards. With the wide application and popularization of wood products in household and public places, the problem of fire safety has become more prominent. As one of the main raw materials of wood products, wood-based panels have extremely important flame retardant properties. The flame retardant properties of wood-b...

AI Technical Summary

Problems solved by technology

Ordinary flame-retardant wood-based panels are soaked in wood-based panels or raw materials in flame-retardant adhesives. It has certain flame retardant properties, but the flame retardant wood-based panels prepared by this preparation method are prone to problems such as moisture return, frost return, glue opening, and unstable flame retardant performance during use; there are also a small number of flame retardant adhesives that can be coated Cloth is used to make a flame-retardant layer on the surface of the wood-based panel, but the preparation process is cumbersome, and because the flame-retardant layer is mostly white or black, it is not beautiful, and it is necessary to cover the surface with leather paper or decorative surface to cover the flame-retardant layer itself. Phase, this not only increases the difficulty of the process, but also increases the production cost
