A production process of flame retardant board

Abstract

The invention belongs to the technical field of wood processing and handling, and particularly discloses a production technology for an anti-flaming plate. The technology comprises the following stepsof 1, selecting materials, wherein leftover materials obtained after aspen, willow or other wood are processed are adopted as plate raw materials, and then the raw materials are stewed and softened;2, performing hot grinding; 3, performing mixing; 4, performing prepressing; 5, performing hot pressing; 6, preparing a solvent, wherein the solvent is prepared from 1.8-4 parts of anhydride with theconcentration being 20-40% and 1 part of fire retardant, the plate obtained in step 5 is soaked with the solvent, pressurizing is performed to 0.8-1.2 mpa, and soaking is performed for 1-1.5 h; aftersoaking is completed, vacuumizing is performed to reach 100-200 Pa, and the plate with the water content being 5-8% s obtained; 7, performing gluing; 8, performing press fitting. The anti-flaming plate produced by adopting the technology can improve the processing efficiency of the anti-flaming plate, and the obtained anti-flaming plate is good in fire retardant effect.

Description

technical field [0001] The invention belongs to the technical field of wood processing and treatment, and in particular relates to a production process of a flame-retardant board. Background technique [0002] A plank is a plank made of whole wood. Wooden boards are often used in wooden doors, desks and other furniture. These boards are durable and have natural textures, making them the best choice for making high-end furniture. Wooden boards are generally classified according to the actual name of the board, and there is no uniform standard specification. [0003] Existing wood boards are flammable materials. There is a big safety hazard in using these wood boards to process products, that is, they are not fireproof and flammable. With the enhancement of people's safety awareness, boards with flame retardant function are more and more popular.

Problems solved by technology

[0003] Existing wood boards are flammable materials. There is a big safety hazard in using these wood boards to process products, that is, they are not fireproof and flammable. With the enhancement of people's safety awareness, boards with flame retardant functions are more and more popular among people.

There are many flame retardant treatment methods for wood, mainly including atmospheric pressure impregnation method, hot pressing method, composite method, etc. Among them, the atmospheric pressure impregnation method is to soak the wood board in the flame retardant solution under normal pressure conditions. The process is simple, but this method needs to soak the plate for a long time, the processing efficiency is low, and it is only suitable for processing thinner materials

The hot pressing method is suitable for the production of wood-based panels, and has little effect on the physical and mechanical properties of the board, but when the flame retardant is infiltrated into the board by hot pressing, it is easy to cause bubbles on the surface of the board
