Abstract
The invention discloses a fire retardant for wood, and a preparation method and a treatment process thereof. The fire retardant for wood is prepared from the following raw materials in percentage by weight: 40 to 60 percent of silica sol, 5 to 20 percent of sodium octaborate tetrahydrate, 1 to 20 percent of ammonium polyphosphate, 1 to 20 percent of carbonate and 0 to 53 percent of water. The preparation method comprises steps of: putting the substances into a stirrer, and uniformly mixing fully to obtain the flame retardant. During use, wood is put into a treatment tank, and is vacuumized, the flame retardant is injected at normal temperature, the treatment tank is vacuumized and the vacuum is eliminated so as to obtain the flame-retardant wood. By utilizing advantages of nontoxicity, environmental friendliness, high flame-retardant efficiency, low price, wide sources and easy preparation of the materials such as the sodium octaborate tetrahydrate and the silica sol, after the materials are compounded, the flame retardant with good anti-loss performance is obtained and can be used for flame-retardant protection of interior and exterior decorative wood and wood structures of buildings.
Description
Technical field
The present invention relates to Wood flame-retarded technology, particularly a kind of wood fire retardant and preparation method thereof and the technology that adopts this fire retardant that timber is handled.
Background technology
Timber is a kind of reproducible green material, is widely used in fields such as building, furniture because of it has good visual characteristic, tactile characteristics, conditioning function and the higher ratio of strength to weight.But the intrinsic inflammability of timber has not only limited its scope of application, has also caused tremendous loss to people simultaneously.For this reason, must carry out flame treatment, to reduce the hidden danger of fire to wood materials.
In the existing fire retardant, emit a large amount of toxic gases when organic fire-retardant burns because of it and cost an arm and a leg, and do not advocate use; The resin type fire retardant because fire resistance is not ideal enough and existence is impregnated difficulty, handled problems such as material darkens, is not widely used.Use the widest inorganic combustion inhibitor, have advantages such as wide material sources, price are low, asepsis environment-protecting, but its resistance leachability can remain to be improved.Along with the enhancing of fire-retardant the reach of science and people's environmental consciousness, the environmental type fire retardant with good resistance leachability energy will be the main developing direction of fire-retarding of wood.
Summary of the invention
In order to overcome the shortcoming and defect that above-mentioned wood fire retardant exists, the object of the invention is to provide a kind of wood fire retardant and treatment process thereof of environment-friendly high-efficiency.In the hope of utilizing silicon dioxide gel, four water, eight Boratexes, APP and carbonate, advantage such as asepsis environment-protecting, flame retarding efficiency height, price economy, wide material sources, preparation are simple is by obtaining good resistance leachability energy after compound.
A kind of environment-friendly high-efficiency wood fire retardant is characterized in that it is formulated by following weight percentages:
Silicon dioxide gel 40-60%;
Four water, eight Boratex 5-20%;
APP 1～20%;
Carbonate 1～20%;
Surplus is a water.
The solid content of described silicon dioxide gel is 20～40%.
Described carbonate is potash or sodium carbonate.
Further purpose of the present invention is to provide the preparation method of above-mentioned environment-friendly high-efficiency wood fire retardant, this method is included as by above-mentioned percentage by weight silicon dioxide gel, four water, eight Boratexes, APP, carbonate, water is put into agitator, after the full and uniform mixing, be fire retardant.
Environment-friendly high-efficiency wood fire retardant of the present invention comprises the steps: the treatment process of timber
A. the timber test specimen is placed vacuum pressed equipment, vacuumize 30～120min with vavuum pump, vacuum keeps 0.094MPa;
B. under vacuum state, in vacuum pressed equipment, inject retardant solution, remove vacuum then;
C. be forced into 0.5～1.5MPa, keep 1～5h, make fire retardant enter timber inside;
D. pressure relief is taken out test specimen, promptly gets fire retarding wood.
The invention has the advantages that:
1, nontoxic, odorless, environmental protection;
2, treatment process is simple, can realize suitability for industrialized production under normal temperature and pressure conditions;
3, fire retardant is the inorganic combustion inhibitor system, flame retarding efficiency height, price economy, wide material sources;
