Embodiment 1

[0012] A method for preparing anticorrosive and flame retardant logs, which includes the following steps:

[0013] (1) Preparation of combustion-supporting preservative: Mix amidine urea phosphate, boric acid, borax, N-(2-benzimidazolyl)-methyl carbamate and water, and the ratio of the raw materials of the amidine urea phosphate is The molar ratio of urea, dicyandiamide, and phosphoric acid is 0.005~0.07:1:0.85-1, the weight of the amidine urea phosphate, boric acid, borax, N-(2-benzimidazolyl)-methyl carbamate and water The proportion is 60~70%: 20~30%: 2~8%: 0.05~0.2%: 10~15%; the urea, dicyandiamide and phosphoric acid are added to water and reacted at 80~100℃ to obtain the amidino phosphate Urea, when the pH value is adjusted to 4.0, add boric acid and borax, keep it at 80~100℃ for 60 minutes, and finally add N-(2-benzimidazolyl)-methyl carbamate to prepare anticorrosive flame retardant;

[0014] (2) Carry out vacuum pressure impregnation treatment on the wood to make the wood...

Abstract

The invention belongs to the field of decorative materials, and discloses a preparation method for corrosion-resistant and flame retardant crude wood. The method is characterized by comprising the flowing steps: firstly, preparing a fire-retardant preservative; secondly, performing vacuum pressure dipping processing on wood, so as to ensure that the wood absorbs the fire-retardant preservative; thirdly, drying the wood subjected to dipping processing through a gradual warming gradient drying method till the water content of the wood is 8 to 12 percent. The crude wood is subjected to corrosion resistant and flame retardant processing, the stability is enhanced, the wood has low possibility of deformation and cracking, and simultaneously the wood has capacities of flame retardance, mould resistance and corrosion prevention; the waterproof and corrosion-resistant performance, the wear-resisting and scratch-resistant performance, and the chemical resistance of the crude wood are improved; glossiness is high and the durability of the crude wood is improved.

Description

Technical field [0001] The invention belongs to the field of decoration materials and relates to a preparation method of anticorrosive and flame retardant logs. Background technique [0002] At present, most indoor floors have poor impact resistance, poor wear resistance, and unstable product performance, which not only wastes resources, but also affects the service life of the floor. Therefore, it is necessary to improve the existing technology. As a home decoration, wood flooring is more and more widely used. Generally, the wood floors laid on the ground mainly adopt three kinds of laminate flooring, multilayer solid wood composite flooring and solid wood flooring. Laminate floor is mainly composed of high-density fiberboard substrate and printing paper surface. This type of laminate floor has disadvantages: fear of water and moisture, high formaldehyde emission, poor decorative effect, airtight, and poor foot feel. Multi-layer solid wood composite flooring is composed of hi...
