Problems solved by technology

[0003] On November 23, 2005, the State Intellectual Property Office of China published the invention patent (its patent number is ZL 00 1 36528.2) of "manufacturing method of artificial wood square". The veneers are then glued with adhesives through the glue machine in turn. The adhesives generally use E0~E1 modified urea-formaldehyde glue, which has fireproof functions, such as modified polyhexenyl acetate, modified melamine or polyurethane series. The amount of glue applied is 90-200 grams per square meter, and double-sided glue is applied to each veneer." This kind of adhesive with fireproof function is used for surface coating. Although the adhesive can partially penetrate into the veneer, it is only Penetrates into the surface layer of the veneer, its fire and flame retardant ability is limited

Embodiment approach 1

[0052] A method for making a flame-retardant recombined decorative material, comprising the following steps:

[0053] (1) Flame retardant treatment of thin wood boards with flame retardants; flame retardants and water are dissolved in a ratio of 1:1 to 1:20 or a flame retardant solution that is proportioned according to the requirements of flame retardant performance is used. The flame retardant described above can be liquid, concentrated or powdered; the dissolved flame retardant solution is added to the container according to the ratio of 1:50 to 50:1 by the volume ratio of the veneer, and the liquid in the container The temperature is 5-100°C and the pressure is 5Mpa. Put the veneer into the container and impregnate it with a flame retardant. After continuous treatment for 0.5-10 hours, release the pressure and take out the veneer.

[0054] Or vacuumize the container, that is, vacuum injection, so that the flame retardant is completely immersed in the veneer;

[0055] Or d...

Embodiment approach 2

[0061] A method for making a flame-retardant recombined decorative material, comprising the steps of:

[0062] (1), bleaching the veneer;

[0063] (3), veneer is dyed;

[0064] (4), veneer is dried;

[0065] (5) Use a flame retardant to treat the veneer with a flame retardant; the flame retardant and water are dissolved in a ratio of 1:1 to 1:20 or the flame retardant solution is mixed according to the flame retardant performance requirements. The above-mentioned flame retardant can be liquid, concentrated or powder; the dissolved flame retardant solution is added to the container according to the ratio of 1:50 to 50:1 to the volume of the veneer, and the liquid in the container The temperature is 5-100°C and the pressure is 5Mpa. Put the veneer into the container and impregnate it with a flame retardant. After continuous treatment for 0.5-10 hours, release the pressure and take out the veneer.

[0066] Or vacuumize the container, that is, vacuum injection method, so that t...

Embodiment approach 3

[0071] The flame-retardant treatment of the veneer with a flame retardant, that is, step (5) is carried out after the veneer is bleached and before drying, and the rest of the steps are the same as in the second embodiment.

[0072] Composition and mechanism of action of flame retardants

[0073] Chemical composition of flame retardants - most of the existing flame retardants can be used for flame retardant treatment of recombined decorative materials and slices, and are generally composed of inorganic salts or organic salts. Commonly used inorganic salts are monoammonium phosphate, diammonium hydrogen phosphate, ammonium sulfate, ammonium polyphosphate, borax and boric acid. Commonly used organic salts are guanylurea phosphate and the like. These salts are cheap and easily seep into wood. It is usually combined in a variety of ways to improve the formulation of flame retardants.

[0074] Mechanism of Action of Flame Retardants - Flame retardants work by altering the combus...

Abstract

The invention relates to a method for producing flame-proof assembled finishing material, which adds one flame-proof treatment in the former production, to make said sheet to be immerged by said flame retardant, while the flame retardant can immerge into inner space, to esterify, etherify and graft copolymerize the hydroxyl group of wood, to separate air, fire resource, fuel or dilute the fuel gas, to change the thermal crack process and control the burning of wood. In said invention, the other physical and chemical properties of wood are changed little.

Description

technical field [0001] The invention relates to a wood processing method, in particular to a method for preparing a flame-retardant recombined decorative material after recombining natural wood. Background technique [0002] The production method of the recombined decorative material is a kind of recombined decorative material, which is made of the rotary-cut (or sliced) veneer of artificial forest or ordinary tree species as the main raw material, and is manufactured by the techniques of veneer coloring, lamination, molding and gluing. It is a new type of wood decoration material with the texture, pattern, color and other characteristics of natural precious tree species wood or other artistic patterns. This decorative material is a new type of wood composite decorative material, which is mainly made of common or fast-growing tree species, such as poplar and paulownia. These tree species grow fast, have a short period of becoming useful, and...
