Problems solved by technology

[0003] The existing ancient wooden structure and wood flame retardant treatment method basically adopts the method of surface painting. This method can only improve the ignition point of the surface layer infiltrated with flame retardant, and cannot prevent the overall wood product from burning under continuous high temperature. combustion
With the development of wood science, some achievements have been made in the research of wood flame retardant. Some processing methods of anti-corrosion and flame-retardant wood have also appeared on the market. The functions of these flame retardants are relatively single. After using these flame retardants to treat wood , to really change the combustion characteristics of wood, so that the wood is flame-retardant, anti-corrosion, and resistant to biological pests, and at the same time, it can rarely produce smoke once the wood is burned, so as to meet the requirements of ancient wooden structures for wood flame-retardant, anti-corrosion, and insect-proof properties. ,Basically no

Embodiment 1

[0033] A method for processing anticorrosive and flame-retardant wood, the method comprising the steps of:

[0034] (1) Material selection: select the wood, and remove unusable wood such as too large cracks and too many wormholes;

[0035] (2) Drying: After the selected timber is piled up, it is sent into a drying kiln for drying until the moisture content of the timber reaches 14%, and it is taken out after the timber is naturally cooled;

[0036] (3) preparation flame retardant mixed solution, flame retardant mixed solution is made up of following components by weight percentage: borax 6%, boric acid 6%, ammonium polyphosphate 35%, ammonium dihydrogen phosphate 35%, ammonium sulfate 16%, Ammonium molybdate 2%, the rest is water; the preparation method is: after weighing each component according to the weight percentage, mixing each component evenly, putting the mixture into the medicine pool and adding water to prepare a saturated solution;

[0037] (4) The cooled wood is s...

Abstract

The invention discloses a processing method of anticorrosive flame-retardant wood. The method specifically comprises the steps of material selection, drying, flame-retardant treatment, drying and thelike. The flame-retardant solid wood processed by means of the method can meet the use requirement for wood, that is to say that, the functions of flame retardance, corrosion prevention and biologicalinsect attack prevention are achieved, and the flame-retardant property of the flame-retardant solid wood exceeds the requirement of the level B1 for wood combustion performance in design specifications.

Description

technical field [0001] The invention relates to a wood processing method, in particular to a processing method of anti-corrosion and flame-retardant wood. Background technique [0002] In recent years, the country has vigorously advocated the development of a green tourism and environmental protection economy. Chinese ancient buildings have shown vigorous new vitality. Various pavilions, pavilions, temples, ancient academies, ancient towns, and ancient dwellings have sprung up, while columns, beams, squares, purlins , rafters, doors, windows, frames, boards and other wooden structures have been widely used. As a kind of combustible material, the extensive use of wood also increases the fire load and fire safety hazards of buildings. The occurrence of the fire has caused huge economic losses to the country, the locality and the people, and also brought serious life threats, affected the normal work, production and living order of the people, and brought strong pain to people...
