Domain.
Background technique
Timber has the characteristics that low heat conductivity, high sound-proofing, easy processing as a kind of reproducible natural resources；Simultaneously
It is inflammable due to the natural quality of timber, and then mechanical property is lost, if dealing with improperly, it may appear that phenomena such as being bent, distorting, from
And influence the normal use of door and window.When wood section moisture content is higher than 20%, fungi is easy to be bred in vivo at it, so as to cause
There is phenomena such as mildew, rot in timber；The effectively any absorption and loss of control Water In Wood, is to ensure that aluminium clad wood doors and windows are used
The key factor of wood section quality.
Timber pickling is common Wooden modifying technique, can assign timber more excellent properties；However, current timber
That there are pickling efficiencies is low for impregnation technology, into timber pore dipping liquid measure it is few, maceration extract is not fire-retardant the problems such as, influence timber
Safe handling.Based on this, the present invention is proposed.
Summary of the invention
The first purpose of this invention is to be to provide aluminium clad wood doors and windows fireproof wood, has fire protection flame retarding, thermal insulation separation
The excellent properties such as heat, sound insulation, dimensionally stable, anti-corrosion, service life length, coat film without surface, retain the original texture of timber, beautiful
Practical, market prospects are huge.
Second object of the present invention is to be to provide the preparation method of aluminium clad wood doors and windows fireproof wood, and the present invention utilizes
Sodium methyl silicate is as hydrophobic crosslinking agent, and using hydrophobic tobermorite as heat-insulating flame-retardant filler, phosphoric acid is gel catalyst, methyl
Cellulose is thickener and surfactant, prepares Wooden modifying functional liquid, and pass through vacuum impregnation technique and microwave drying work
Skill compounds timber with modified function liquid.It is coagulated the study found that colloidal sol-occurs under the catalytic action of phosphoric acid for (1) sodium methyl silicate
Glue reaction, can form Si-O-Si key and tridimensional network, hydrophobic performance and fire protecting performance are excellent；(2) hydrophobic Tuo Beimo comes
Stone has um porous structure, still keeps um porous structure to be not filled in sodium methyl silicate water-based system, has heat-insulated
And fire retardation；(3) methylcellulose not only has hydrophilic radical, but also has hydrophobic grouping, is conducive to hydrophobic tobermorite and exists
It is evenly dispersed in sodium methyl silicate water-based system, and the hydrophobic main chain of methylcellulose and surrounding water molecules are formed by hydrogen bond
It closes, improves the fluid volume of polymer itself, reduce the movable space of Particle free makes to improve system viscosity
When being separated with functional liquid after timber adsorption function liquid, greatly reduce wood internal functional liquid and be lost before gel.
Third object of the present invention is to provide the applications of the fireproof wood, are used for aluminium clad wood doors and windows, show
Excellent comprehensive performance.
In order to achieve the above technical purposes, the present invention provides a kind of aluminium clad wood doors and windows fireproof wood, by timber and timber
The functional liquid filled in hole is constituted；The functional liquid includes sodium methyl silicate, water, phosphoric acid, methylcellulose, hydrophobic Tuo Beimo
Carry out stone.
Further, the timber is one of pine, birch, oak.
Further, the hydrophobic tobermorite can be substituted by hydrophobic fumed silica.
It in this way, tobermorite and fumed silica all have um porous structure, and is inorganic incombustible material, into
And there is heat-insulating flame-retardant performance；Hydrophobic property is not filled it in water-based system Hole, guarantees excellent heat-proof quality.
A kind of preparation method of aluminium clad wood doors and windows fireproof wood of the invention, comprising the following steps:
(1) prepared by functional liquid, and sodium methyl silicate, water, phosphoric acid are mixed, 3h is stirred, and methylcellulose is added, hydrophobic Tuo Beimo comes
Stone continues to stir 0.5h, for use, the wherein mass ratio of sodium methyl silicate, water, phosphoric acid, methylcellulose, hydrophobic tobermorite
For 20:12 ~ 15:0.001 ~ 0.005:0.1 ~ 0.15:5 ~ 8；
(2) timber is dried in microwave device 0.5 ~ 1h, is cooled to room temperature, is placed in vacuum equipment by timber pre-treatment
It vacuumizes, to vacustat, vacuum degree is 10 ~ 100Pa；
(3) vacuum impregnation mixes the functional liquid of step (1) with the timber of step (2) in vacuum equipment, will be more after 0.2h
Remaining functional liquid and wood seperation, standby function lyogel restore normal pressure；
(4) sodium is removed, the timber of step (3) is impregnated in water, solvent displacement, each 12h is replaced 3 times；
(5) timber of step (4) is placed in microwave device dry 1 ~ 2h by microwave drying, obtains aluminium clad wood doors and windows fire prevention wood
Material.
Further, in the step (4), weak-acid cation-exchange resin is added.
In this way, weak-acid cation-exchange resin can significantly improve the removal rate of Na+, reduce solvent displacement number with
Time reduces the generation of industrial wastewater.
Fireproof wood produced by the present invention can be used for aluminium clad wood doors and windows, excellent combination property.
Beneficial effects of the present invention: (1) using the sodium methyl silicate of included hydrophobic grouping as crosslinking agent, have hydrophobic
Property, rigidity, anti-flammability, wood cell wall inflated by sodium methyl silicate system, and cell is filled by it, effectively control Water In Wood
It is any absorption and loss, improve the dimensional stability, service life anti-flammability and mechanical property of timber；(2) tobermorite is by work
Industry waste material flyash is made by hydro-thermal reaction, and waste utilization and emission reduction is environmentally protective；(3) on the one hand methylcellulose is used as surface living
Property agent improve the compatibility of hydrophobic tobermorite and water-based system, be on the other hand used as thickener, avoid functional liquid in gel
It is preceding to be flowed out from timber；(4) before impregnating, microwave drying treatment is carried out to timber, most of water in timber is excluded in advance, improves function
It can the loading of liquid in wood；(5) vacuum impregnation technique can to form negative pressure in timber hole, improve functional liquid filling
The amount of timber pore；(6) microwave drying process makes wood internal and external heat drying simultaneously, with traditional heating mode phase
Than significantly improving drying efficiency, making the high efficiency of thick matter timber is filling-modified to be achieved；(7) equipment that the present invention uses is equal
For working standard equipment, it is easy to accomplish industrialized production.
