Abstract
The present invention relates to a fire-retarding and antiseptic chemical agent for treating wood, which is prepared from ammonium polyphosphate soluble in hot water, boracic matter, quaternary ammonium salt, etc.
Description
What the present invention relates to is that a kind of anticorrosion using of fire-retarding of wood that contains organic composition handled medicament.
Extensive for using, the natural timber that consumption is big, improving its fire-retardant fireproof performance and antiseptic property as far as possible is particular importance.The processing medicament that can have fire-retardant and anticorrosion dual-use function simultaneously can be divided into two classes at present, one class is made up of pure inorganic constituents, as disclosed in documents such as Russian Patent SU1017500A and SU1255435A be exactly inorganic type, it is except that problems such as the toxicity of ingredient itself and pollution, and weak point also is with the timber wettability of its processing big.Another kind of is the processing medicament that contains organic principle, as just introduced the phosphate that contains fluoride, ammonium and the processing material of compositions such as higher fatty acids or urea respectively in Russian Patent SU613894B and SU663581B.Wherein contained fluoride also owing to its poorly water-soluble has influenced dried salt content in the processed timber, has caused the reduction of fire retardant effect, thereby only should use as the coating form except that toxicity that exists and contaminative.
The object of the present invention is to provide a kind of low toxicity, anticorrosion the using of the fire-retarding of wood that contains organic composition pollution-free and the fire retardant, anticorrosive excellent performance to handle medicament.
The composition of the said fire-retarding preservative for wood of the present invention (weight %) is: the polyphosphoric acid ammonium salt 64-72 that can dissolve in the hot water, boron substance 22-35, quaternary ammonium salt material 3-7.APP is present known good applied fireproofing, has water-soluble and branch water-insoluble by the big I of its degree of polymerization.Though experiment shows its degree of polymerization increase water-soluble degree is reduced, the fire-retardant fireproof performance improves thereupon, and the timber wettability of processing is little.When guaranteeing in common hot water below 100 ℃, to make under the prerequisite of its dissolving, adopt the APP of high polymerization degree can make it obtain satisfied unification in anti-flammability and for handling between the required dissolubility of timber as far as possible.When using chemicals treatment timber of the present invention, only need be controlled at below 100 ℃, for example carry out under the heating condition just can not having the problem aspect its dissolubility 50-80 ℃ make things convenient for.Another advantage that this treatment conditions also have simultaneously is the range of choice that can enlarge boron substance essential to the invention.Though, often make actual use very inconvenient or be restricted because of the relation of its solubility as some salts such as boraxs because boron substances such as boron, boric acid and various borates are known fire proofings.And in the present invention,, also help reducing cost even the boron substance that solubility is very little in the cold water such as borax even also can be used alone has both helped reducing the component kind.
Quaternary ammonium compound uses existing research and report as the wood preservation material.But in the present invention, be used with other component, it also has good flame fire prevention booster action simultaneously and improves the infiltrative surface-active effect of medicament.For improving its combination property in these areas, the present invention advises should having at least on the one hand one and is C in its each substituted hydrocarbon radical
7Above long chain hydrocarbon is as the existing C that introduces

10Two long chain hydrocarbons etc., help improving antiseptic property; Serve as better to select quaternary ammonium halides salt for use on the other hand, more help strengthening its fire-retardant fireproof performance.
For reducing to the various Effect on Performance of timber itself, handle the acid-base value of medicament and be advisable with the nearly neutrality of pH6-7, therefore in treating of wood medicament of the present invention, can suitably select suitable acid-base modifier as required for use in case of necessity.For example when the fire-retarding preservative of forming by said components of the present invention is alkalescence, can select an amount of inorganic acid commonly used for use, example hydrochloric acid, sulfuric acid, phosphoric acid etc. are regulated pH, wherein especially to select for use phosphoric acid for well, because of its deacidification warm in nature and and corrosivity little outside, also can have auxiliary fire resistance.
This shows, collaborative by cooperatively interacting of the above-mentioned component that respectively has a multiple action, make treating of wood medicament of the present invention both simplify composition as far as possible, can reduce the consumption consumption in the actual use again, also can improve effect simultaneously in fire-retardant and anticorrosion each side.The timber that the aqueous solution that uses fire-retarding preservative 10-20% of the present invention is handled under 50-80 ℃ of condition carries out the fire-retardant fireproof test and shows that processing medicament of the present invention can stop flaming combustion, can suppress flameless combustion again.In dried salt amount is 35Kg/m
3The time, rate of lostmass after fire about 15%, burning average residual length 18-21cm.Treating of wood medicament of the present invention belongs to lower toxicity, and is not volatile, and the physical property of timber is not had influence, and its thermal decomposition product is nonirritant and corrosivity also.The relevant data of fire-retardant fireproof test sees Table 1.The corrosion-resistanting test that with the birch is test material the results are shown in Table 2.
Some concrete composition embodiment as fire-retarding of wood anti-corrosion agent of the present invention sees Table 3, and quaternary ammonium salt wherein is a chlorination dimethyl benzyl dodecyl ammonium.But these examples should not constitute limitation of the scope of the invention.
