Flame retardant, preparation method thereof and method for preparing artificial boards from same

Abstract

The invention discloses a flame retardant, which comprises the following components in percentage: 12 to 20 percent of melamine derivative, 18 to 30 percent of boron-containing compound and 50 to 70 percent of water. The invention mainly solves the problems that the flame retardant has low flame retardancy, strong moisture absorption, high loss tendency and the like, and the flame retardant adding method has high energy consumption, low efficiency and the like in the conventional artificial board flame retardancy technology. The flame retardant can be directly mixed in an adhesive; after one-time board manufacturing, the artificial board has flame retardancy; and the flame retardant has the advantages of saving the manufacturing process flow for the flame-retardant artificial board and saving cost.

Description

technical field [0001] The invention relates to the technical field of flame retardant for wood-based panels, and relates to a flame retardant for wood-based panels mixed with an adhesive and a preparation method thereof. Background technique [0002] Wood-based panels are wood fiber raw materials separated into various shapes of unit materials by mechanical processing, and then combined and pressed into various boards, including medium density fiberboard, particle board, plywood and other varieties, which are widely used in furniture manufacturing and construction industries. , Interior decoration industry. However, wood-based panels are combustible materials, and there is a greater fire risk in use. In order to reduce fire hazards and increase public safety, it is very necessary to research and develop flame-retardant wood-based panels and corresponding flame retardants, and the field of wood-based panel flame-retardant technology has also emerged. [0003] Wood-based pa...

AI Technical Summary

Problems solved by technology

The above-mentioned flame retardants have the following disadvantages: low flame retardant efficiency and large addition amount; flame retardants have strong hygroscopicity, are prone to deliquescence and frost return, and have a large loss tendency; Stability, processing performance, use performance, etc. are greatly affected; flame retardants are corrosive to metal components, etc.

[0004] The existing methods of adding flame retardants generally have the following three methods. The first method is to soak or spray raw materials such as fibers, shavings, and veneers with a flame retardant solution, and then produce wood-based panels after drying. The disadvantage of this method is that it requires Increasing the production process will increase energy consumption and reduce production efficiency; the second method is to mix solid flame retardants with raw materials such as fibers and shavings, and use them. The disadvantage of this method is that the flame retardants are not easy to disperse evenly, and the loss of flame retardants is large The third method is to produce the finished wood-based panel first and then soak it in the flame retardant solution. The disadvantage of this method is that it is easy to cause the wood-based panel to be deformed and glued, and the energy consumption will be increased during drying.
