Abstract

The invention discloses a wood flame-retardant preservative and a process for preparing flame-retardant and anti-corrosion wood by using the same, belonging to the field of organic chemistry and wood treatment technology. The wood flame retardant preservative of the invention is prepared by mixing 50-70% of BPW, 15-30% of diammonium phosphate, 10-30% of boric acid and 1-5% of ammonium molybdate according to the weight percentage. The invention prepares the flame-retardant and anti-corrosion wood (Pine sylvestris sylvestris) according to the following steps: after the wood is dried to a constant weight, it is placed in a flame-retardant liquid for vacuum pressure impregnation treatment, and then the flame-retardant wood is taken out and dried to obtain the flame-retardant anti-corrosion wood. The flame retardant preservative of the present invention adopts BPW, sodium dihydrogen phosphate and boric acid as main materials. The flame retardant prepared by mixing these several substances in the present invention has good flame-retardant, anti-corrosion and smoke-suppressing properties, good stability, and is non-toxic and odorless, and can be widely used in chemical construction and other fields; and it is easy to impregnate wood , so that the treated wood has good flame-retardant and anti-corrosion properties, and expands its scope of use.

Description

technical field [0001] The invention belongs to the field of organic chemistry and wood treatment technology, and relates to a flame-retardant, anti-corrosion and smoke-suppressing wood flame retardant and a process for treating solid wood by using the same. Background technique [0002] The environmental protection of wood has attracted wide attention in its application, but its use is limited due to its flammability and easy corrosion. The research on wood flame retardants has attracted widespread attention, but there are not many types that can be put into practical application at present. With the increasing requirements for wood flame retardants, our research on flame retardants has begun to focus on comprehensive research on the effects of flame retardants such as flame retardancy, smoke suppression, anti-corrosion, and insect protection. At the same time, due to the more stringent requirements for flame retardants in relevant regulations, this also requires more inve...
