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

A kind of preparation method of antiseptic fire-retardation log
Technical field
The invention belongs to finishing material field, relate to a kind of preparation method of antiseptic fire-retardation log.
Background technology
At present, the floor of indoor laying, impact resistance is poor mostly, wears no resistance, and properties of product are unstable, not only waste resource, and affected the service life on floor.Therefore, be necessary prior art to improve.Timber floor, as a kind of home decoration, is more and more used widely.The timber floor that lay on general ground mainly adopts these three kinds of consolidated floor and multi-layer solid wood composite floor and solid wooden floor boards.Consolidated floor is mainly made up of high-density fiber plate substrate and printing paper surface, this consolidated floor existent defect: water funk fearness tide, and burst size of methanal is high, and decorative effect is poor, and airtight, and feel is poor.Multi-layer solid wood composite floor is to be that high-quality broadleaf specification lath edge is spelled or view picture plank by surface, and multi-plywood is that base material forms, and carries out leaching paint PROCESS FOR TREATMENT on surface.The shortcoming of this multi-layer solid wood composite floor is that paint composition contains harmful material, can not accept for broad masses.
Timber is the main material of making raw wood floor, timber belongs to combustible material, although disclose the treatment process such as some fire-retarding of wood, protection in existing prior art, these treatment process all exist complex process, the processing time is long, the poor mechanical property of timber after treatment, intensity is low, the poor dimensional stability of timber, and fire retardant easily runs off, cause fire-retarding of wood DeGrain after treatment, antiseptic property is low.The processing such as enhancing, anticorrosion, fire-retardant and size stabilization are combined the technical research of timber multifunction, and majority, still in laboratory stage, is difficult to real application.
Summary of the invention
The object of the invention is to be difficult for anticorrosion and inflammable deficiency for timber in prior art, a kind of its preparation method of antiseptic fire-retardation log is provided, antiseptic fire-retardation treatment technology of the present invention, can make the stability of log strengthen, and has fire-retardant, mildew-resistant and the performance such as anticorrosion.
The preparation method of a kind of antiseptic fire-retardation log of the present invention, it comprises the following steps:
(1), prepare combustion-supporting anticorrisive agent: guanylurea phosphate, boric acid, borax, N-(2-benzimidazole base)-methyl carbamate and water are mixed, make antiseptic fire-retardation agent;
(2), timber is carried out to vacuum pressed impregnation process, make the agent of timber absorption antiseptic fire-retardation: the process tank of first timber being put into sealing, vacuumize processing, relative vacuum degree-0.1MPa, then import wood preservation fire retardant in process tank, then process tank is carried out to pressurized treatments 2 hours, absolute pressure 2MPa, finally lays down pressure and emptying antiseptic fire-retardation agent; Aforesaid operations is processed 2~3 times repeatedly, makes timber fully absorb antiseptic fire-retardation agent, obtains impregnation process material;
(3), dry: to adopt the gradient drying means progressively heating up to be dried to impregnation process material: to take out the impregnation process material in process tank, impregnation process material is first predrying at 50 ℃ of temperature, adopt the temperature incremental manner of 10 ℃/2~3 days to be dried, being dried to moisture content is 8~12% again.
The proportioning of the raw material of described guanylurea phosphate is that the mol ratio of urea, dicyandiamide, phosphoric acid is 0.005~0.07:1:0.85~1.Described guanylurea phosphate, boric acid, borax, N-(2-benzimidazole base)-methyl carbamate and water weight proportion are 60~70%:20~30%:2~8%:0.05~0.2%:10~15%.Described urea, dicyandiamide, phosphoric acid are added to the water, 80~100 ℃ of reactions make guanylurea phosphate, and regulating pH value is 4.0 o'clock, adds boric acid, borax, 80~100 ℃ of insulations 60 minutes, finally add N-(2-benzimidazole base)-methyl carbamate.
Beneficial effect of the present invention: log prepared by the present invention is through antiseptic fire-retardation treatment technology, and stability strengthens, Undeformable and indehiscent has fire-retardant, mildew-resistant and the performance such as anticorrosion simultaneously; Water-fast anti-corrosive properties, wear-resisting scratch-resisting, chemical proofing, high gloss, durability of log etc. are improved.
The specific embodiment
Embodiment 1
A preparation method for antiseptic fire-retardation log, it comprises the following steps:
(1), prepare combustion-supporting anticorrisive agent: guanylurea phosphate, boric acid, borax, N-(2-benzimidazole base)-methyl carbamate and water are mixed, the proportioning of the raw material of described guanylurea phosphate is that the mol ratio of urea, dicyandiamide, phosphoric acid is 0.005~0.07:1:0.85~1, and described guanylurea phosphate, boric acid, borax, N-(2-benzimidazole base)-methyl carbamate and water weight proportion are 60~70%:20~30%:2~8%:0.05~0.2%:10~15%; Described urea, dicyandiamide, phosphoric acid are added to the water, and 80~100 ℃ of reactions make guanylurea phosphate, and regulating pH value is 4.0 o'clock, add boric acid, borax, 80~100 ℃ of insulations 60 minutes, finally add N-(2-benzimidazole base)-methyl carbamate, make antiseptic fire-retardation agent;
(2), timber is carried out to vacuum pressed impregnation process, make the agent of timber absorption antiseptic fire-retardation: the process tank of first timber being put into sealing, vacuumize processing, relative vacuum degree-0.1MPa, then import wood preservation fire retardant in process tank, then process tank is carried out to pressurized treatments 2 hours, absolute pressure 2MPa, finally lays down pressure and emptying antiseptic fire-retardation agent; Aforesaid operations is processed 2~3 times repeatedly, makes timber fully absorb antiseptic fire-retardation agent, obtains impregnation process material;
