Abstract

The invention discloses a wood fire retardant anticorrosive processing method including five steps of wood preprocessing, preparation of a flame retardant preservative, preparation of a flame retardant preservative solution, impregnation and post-drying processing. The fire retardant preservative is prepared from propylene glycol, bronopol, 4, 5-dichloro-N-octyl-4-isothiazolin-3-one, 2-chloro-5-hydroxy meta-xylene, dithiocyano methane, dodecyl dimethyl benzyl ammonium chloride, N-(2-benzimidazole)-methyl carbamate, diammonium phosphate, zinc borate, ammonium molybdate and fatty alcohol polyoxyethylene ether compound. The beneficial effect is that the wood fire retardant anticorrosive processing method is simple in process, practical, efficient, environmentally-friendly, and easy to control, and the like, the processed wood maintains the original features, meanwhile has excellent flame retardant, anti smoke, anti-corrosion, anti mildew, pest control, antibacterial, anti erosion and other muti-function modification effect, is stable in performance, non-toxic, and environmentally-friendly, and can be widely used in indoor and outdoor decoration, building material, furniture material and other fields.

Description

technical field [0001] The invention relates to the technical field of wood production, in particular to a method for fire-retardant and anti-corrosion treatment of wood. Background technique [0002] As a natural and renewable resource, wood has the advantages of beautiful texture, natural color, comfortable texture, good plasticity, and easy processing, so it is used as an ideal material for building decoration and furniture manufacturing. However, due to long-term contact with oxygen, light, and moisture, wood is easily corroded by insects and bacteria, and it is easy to burn, which will greatly limit the application effect and application field of wood. Therefore, before the use of wood, it is usually necessary to carry out necessary flame-retardant and anti-corrosion treatment to improve its performance and prolong its service life. Contents of the invention [0003] The purpose of the present invention is to provide a simple, practical, efficient and environment-fri...
