Wood fire-retarding treatment method

Abstract

The invention discloses a wood fire-retarding treatment method. Wood is sawed, segmented and sliced according to a designated size, layered, piled and put into a kiln, circulation hot air is injected,then phosphorus nitrogen system fire-retardant aqueous solution is prepared, the surface of the wood is cooled to 60-70DEG C, put into a basket to be impregnated into the fire-retardant aqueous solution, and then the impregnated wood is fed to a kiln and dried. The wood treated by using this method has improved fire-retardance and reduced fire retardant amount, and both combine economy and fire-retardance effects well. Via test, the wood prepared by the invention is good in fire retardance effect, and is accepted by floor and furniture factories.

Description

technical field [0001] The invention relates to a wood flame-retardant treatment method, which belongs to the technical field of production of wooden floor and furniture solid wood boards. Background technique [0002] Nowadays, with the improvement of people's living standards, most of the new houses are decorated with solid wood furniture or log floors. These wooden furniture are flammable materials. Due to technical limitations, manufacturers generally only use phosphorus-nitrogen flame retardants to treat logs. The simple flame retardant treatment is not standardized. The flame retardant is mostly attached to the surface and cannot penetrate into the wood body. It cannot achieve the desired flame retardant effect and poses a great threat to the safety of users' lives and property. Contents of the invention [0003] The object of the present invention is to provide a fire-retardant treatment method for wood. The fire-retardant agent of the wood treated by the method pen...
