Embodiment Construction

[0013] The technical solutions of the present invention will be further described below in conjunction with specific preferred embodiments.

[0014] A high-efficiency and environmentally friendly flame retardant for wood impregnation, its components are: 20% phosphoric acid, 8% borax, 8% boric acid, 40% water-soluble ammonium polyphosphate, 20% aluminum sulfate, molybdic acid Ammonium 4%. Wherein, the mass concentration of the phosphoric acid is 80%-90%.

[0015] The preparation method is as follows: weighing each component according to the mass percentage, and fully mixing uniformly to obtain the high-efficiency and environment-friendly flame retardant for wood impregnation of the present invention.

[0016] Adopt the high-efficiency environment-friendly flame retardant for wood impregnation of the present invention to the treatment process step of wood as follows:

[0017] (1) Dry the wood to be treated so that its moisture content is ≤12%;

[0018] (2) Preparation of fla...

Abstract

The invention discloses an efficient environmentally-friendly fire retardant for wood impregnation, and a treatment technology thereof. The efficient environmentally-friendly fire retardant for wood impregnation comprises, by mass, 10-25% of phosphoric acid, 5-10% of borax, 5-10% of boric acid, 30-45% of water-soluble ammonium polyphosphate, 5-30% of aluminum sulfate and 3-6% of ammonium molybdate. Compared with fire retardants in the prior art, the efficient environmentally-friendly fire retardant has smoke elimination and inhibition effects through the addition of ammonium molybdate, contains P, N and B fire retardation components, and has the advantages of good fire retardation effect, no halogen, low toxicity, no irritation, no corrosion, good stability in the use process, difficult degradation or loss, abundant sources of raw materials, low cost and use convenience.

Description

technical field [0001] The invention relates to the technical field of wood flame retardants, in particular to a high-efficiency and environment-friendly flame retardant for wood impregnation and its treatment process. Background technique [0002] Wood is widely used in the fields of construction, transportation, furniture and interior decoration, but its flammability can easily bring fire hazards, causing casualties and property losses. The use of appropriate flame-retardant treatment will further expand the use of wood and protect people's property. It is of great significance to ensure the security and stable growth of the national economy. Since wood is a porous and complex natural organic substance mainly composed of cellulose, hemicellulose and lignin, it does not dissolve or melt under normal processing and use conditions, and wood contains a large number of hydroxyl groups and hydroxymethyl groups, etc. Oxygen-containing polar groups have strong hygroscopicity and ...
