Problems solved by technology

Drying treatment is required after dipping, which increases the complexity of the flame retardant process, and is limited by the permeability of the wood material itself, and has the disadvantages of losing the flame retardant effect due to the precipitation and loss of the flame retardant. Most Outstanding Issues in Technology
The additive method has the problem of the adaptability of the adhesive and the flame retardant. If the adaptability is poor, it will not only be impossible to mix and use, but also have a negative impact on the bonding performance of the adhesive. This process also increases the complexity of production.
The disadvantage of fire retardant coating treatment is that the opacity of most fire retardant coatings cannot meet the decoration requirements in the use of wood materials.

Abstract

The invention relates to a preparation method of a flame-retardant adhesive for an artificial board, and belongs to the technical field of adhesives. The flame-retardant adhesive for the artificial board is prepared by adding the modified superfine magnesium hydroxide powder, and the superfine magnesium hydroxide flame retardant can release moisture, absorb heat and reduce the actual temperature of flame on the surface of the board when being heated and decomposed, so that the speed of degrading a polymer into low molecules is reduced. The uniformly released water vapor can dilute the concentration of oxygen on the surface of the wood, so that the combustion on the surface of the wood cannot be continued; the ultrafine uniformly-dispersed magnesium hydroxide flame retardant can react withwood at high temperature to decompose non-combustible gas such as carbon dioxide, and the fire extinguishing effect is achieved by isolating air.

Description

Technical field[0001]The invention relates to a method for preparing a flame-retardant adhesive for artificial boards, and belongs to the technical field of adhesives.Background technique[0002]In recent years, wood materials have been widely used in decoration and building materials. However, the natural flammability of wood products used in homes and public places constitutes a fire hazard. With the popularization of wood products in homes and public places, fire safety issues have become more prominent. Therefore, in order to reduce the occurrence of fires, considering the safety of human life and property, it is necessary to research and develop flame-retardant wood materials and use wood materials with flame-retardant functions, and it is also the most concerned issue in the industry.[0003]The main method of the existing wood material flame retardant technology is to impregnate the flame retardant material into the wood, or mechanically mix the flame retardant material with the ...
