Description

DK 152263 BDK 152263 B

iin

Opfindelsen angår et træbeskyttelsesmiddel af den i indledningen til krav 1 angivne art.This invention relates to a wood preservative of the kind set forth in the preamble of claim 1.

Det er kendt at anvende et koncentrat med et højt indhold af borsyre, f.eks. en blanding af diethanolamin, 5 b.orsyre og vand, som træbeskyttelsesmiddel (DE patent- skrift nr. 21 40 051).It is known to use a concentrate with a high content of boric acid, e.g. a mixture of diethanolamine, 5 b.oric acid and water as a wood preservative (DE patent no. 21 40 051).

Ved anvendelse af alkanolaminer som opløsningsmiddel for borsyren kan koncentraterne kun under visse betingelser anvendes som flammebeskyttelsespåstrygninger.Using alkanolamines as a solvent for the boric acid, the concentrates can only be used as flame retardants under certain conditions.

10 Disse koncentrater er stærkt hygroskopiske og frembringer på trods af initial udtørring efter kortere eller længere tid stærkt klæbende anstrøg på træet, i afhængighed af luftfugtighed og temperatur.10 These concentrates are highly hygroscopic and, despite initial drying, produce strong adhesive stresses on the wood for shorter or longer periods, depending on humidity and temperature.

Ved anvendelse af andre aminer, f.eks. polyaminer, 15 forekommer der en for stærk tørring på træet, således at anstrøgene i det lange løb bliver sprøde og udviser revnedannelser. Ved anvendelse som træbeskyttelsesmiddel ved beskyttelse af randen (påstrygning, sprøjtning, neddykning), hvor koncentratet fortyndes med 20 vand (sædvanligvis 90-75 vægt-?o vand), er indtrængning en af borsyren i træet påvirket i skadelig retning på grund af den manglende indtrængning af aminen, der straks bindes til træets overflade.When using other amines, e.g. polyamines, 15, there is too strong drying on the wood, so that the strokes in the long run become brittle and exhibit cracking. When used as a wood preservative for protection of the rim (ironing, spraying, dipping), in which the concentrate is diluted with 20 water (usually 90-75% by weight water), penetration of one of the boric acid in the wood is adversely affected by the lack of penetration of the amine which immediately binds to the surface of the tree.

Træbeskyttelsesmidlet ifølge opfindelsen er ejendomme-25 ligt ved det i den kendetegnende del af krav 1 angivne.The wood preservative according to the invention is peculiar to that of the characterizing part of claim 1.

Det har vist sig, at træbeskyttelsesmidlet ifølge opfindelsen ikke er behæftet med de ovenfor angivne ulemper. Træbeskyttelsesmidlet ifølge opfindelsen egner sig både til beskyttelse af træet før angreb hidrørende fra svam-30 pe eller insekter og som flammebeskyttelsesmiddel til· beskyttelse af træet før opblussen på grund af ild.It has been found that the wood preservative according to the invention does not suffer from the disadvantages mentioned above. The wood preservative according to the invention is suitable both for protection of the tree before attacks from fungi or insects and as a flame retardant for protecting the tree before fire due to fire.

Ued en vandopløselig, organisk amin skal man f. eks. forstå: primær , sekundær , tertiær organisk amin eller diamin, triamin, tetramin eller pentamin eller et hydroxyderivat eller methoxyderivat af de angivne 5 aminer. Sådanne aminer er f. eks. monoethanolamin, diethanolamin, triethanolamin, monomethylethanolamin, methyldiethanol.amin, ethylamin, diethylamin, propylamin, methoxyethylamin, methoxypropylamin, dimethylethanol-amin, 1,2-propylendiamin, 3-amino-l-methylaminopropan, 10 dipropylentriamin, tripropylentetramin, tetrapropy- lenpentamin eller blandinger deraf. Man foretrækker monoethanolamin.For example, a water-soluble organic amine is understood to mean: primary, secondary, tertiary organic amine or diamine, triamine, tetramine or pentamine or a hydroxy derivative or methoxy derivative of the indicated 5 amines. Such amines are, for example, monoethanolamine, diethanolamine, triethanolamine, monomethylethanolamine, methyldiethanolamine, ethylamine, diethylamine, propylamine, methoxyethylamine, methoxypropylamine, dimethylethanolamine, 1,2-propylenediamine, 3-amino-1-methylaminopropane, dipropylene tripropylenetetramine, tetrapropylene pentamine or mixtures thereof. Monoethanolamine is preferred.

I forbindelse med de fleste aminer er indrøring af borsyre i aminerne tilstrækkelig. Da de fremkomne 15 væsker dog kan være for viskose, kan det anbefales at anvende en ringe vandtilsætning ved forarbejdningen.For most amines, boric acid stirring in the amines is sufficient. However, since the resulting 15 liquids may be too viscous, it is recommended to use a low water addition during processing.

Over en pH-værdi på ca. 6,5 til 7,5 lader koncentratet sig let fremstille. Under disse pH-værdier vanskeliggøres opløsning af borsyren i aminerne eller polyaminer-20 ne. En pH-værdi på ca. 7,5 til 8,0 svarer til et blandingsforhold på ca. 1 mol amin til 3 til 4 mol bor-syre. Ved polyaminerne må i hvert tilfælde ca. 1 nitrogenatom af polyaminmolekylet reagere med 3 mol borsyre, dvs. der foreligger f. eks. et blandingsforhold på 1 25 mol triamin til 9 mol borsyre. Ved forøgelse af amin-eller polyaminandelen kan man indstille højere pH-værdier efter behov.Above a pH of approx. 6.5 to 7.5 allow the concentrate to be readily prepared. Under these pH values, dissolution of the boric acid in the amines or polyamines is made more difficult. A pH of approx. 7.5 to 8.0 corresponds to a mixing ratio of approx. 1 mole of amine to 3 to 4 moles of boric acid. In each case, the polyamines must contain approx. 1 nitrogen atom of the polyamine molecule reacts with 3 moles of boric acid, ie. for example, there is a mixing ratio of 1 25 moles of triamine to 9 moles of boric acid. By increasing the amine or polyamine content, higher pH values can be adjusted as needed.

Natriumpolyborat (Na^BgO^^.3^0) er en fast, vandopløselig forbindelse. Den opstår ved omsætning mellem 50 borsyre og borax i vand. Træbeskyttelsesmidlet ifølge opfindelsen kan derved indeholde natriumpolyborat el- 3Sodium polyborate (Na 2 B 2 O 3. 3 50) is a solid, water-soluble compound. It arises from reaction between 50 boric acid and borax in water. The wood preservative according to the invention may thereby contain sodium polyborate or 3

ler en blanding af borsyre eller borax, da disse, som ovenfor angivet, omdannes til natriumpolyborat.is a mixture of boric acid or borax since, as indicated above, it is converted to sodium polyborate.

Ved fremstillingen af træbeskyttelsesmidlet ifølge opfindelsen foretrækker man tilsætningen af en blanding 5 af borsyre og borax eller den alternerende tilsætning af borsyre og borax til den vandige blanding af den vandopløselige amin og borsyre.In the preparation of the wood preservative according to the invention, the addition of a mixture of boric acid and borax or the alternate addition of boric acid and borax to the aqueous mixture of the water-soluble amine and boric acid is preferred.

Træbeskyttelsesmidlet ifølge opfindelsen indeholder som angivet 20 til 60 vægt-% af et koncentrat af den van-10 dige blanding af borsyre og en vandopløselig organisk amin. Hertil tilsætter man 40 til 80% af natriumpolyborat eller fortrinsvis af den dermed ækvivalente mængde af blandingen af borsyre og borax. Vægtforholdet borsyre til borax i den tilsatte blanding andrager hen-15 sigtsmæssigt 2:1 til 1:1,2, fortrinsvis 1:1.The wood preservative of the invention contains, as indicated, 20 to 60% by weight of a concentrate of the usual mixture of boric acid and a water-soluble organic amine. To this is added 40 to 80% of sodium polyborate or preferably of the equivalent amount of the boric acid and borax mixture. The weight ratio of boric acid to borax in the added mixture is suitably 2: 1 to 1: 1.2, preferably 1: 1.

Træbeskyttelsesmidlet ifølge opfindelsen er f.eks. en viskos træ- og ildbeskyttelsespasta med et indhold på i alt 40 vægt-% ^er * '/and af en temperatur på 20° C besidder en opløselighed på over 25¾.The wood preservative of the invention is e.g. a viscous wood and fire protection paste having a total content of 40 wt% ^ is * '/ and of a temperature of 20 ° C has a solubility of over 25 °.

20 Pastaen fremstiller man f.eks. ved langsom indrøring af natriumpolyborat i blandingen af borsyre og amin eller ved indrøring af borsyre/borax i denne blanding.For example, the paste is prepared. by slow stirring of sodium polyborate in the mixture of boric acid and amine or by stirring boric acid / borax in this mixture.

Herved opstår der under røreprocessen ved reaktion mellem borsyre og borax under fraspaltning af vand natrium-25 polyborat, der udfælder i meget finkrystallinsk form (1- 10yU m) og derpå danner pastaen sammen med blandingen af borsyre og amin.Thereby, during the stirring process, reaction occurs between boric acid and borax during the decomposition of water sodium polyborate, which precipitates in a very fine crystalline form (1 to 10 µm) and then forms the paste together with the mixture of boric acid and amine.

Blandingsforholdet i blandingen borsyre/borax vælges i afhængighed af pH-værdien af blandingen borsyre/amin 30 på sådan måde, at træbeskyttelsesmidlet ifølge opfindel sen og dennes vandige opløsninger udviser en pH-værdi mellem 6 og 8 ved 20° C. Til træbeskyttelsesmidlet ifølge opfindelsen kan man efter behov tilsætte mere eller 4The mixture ratio in the boric acid / borax mixture is selected depending on the pH of the boric acid / amine 30 mixture such that the wood preservative of the invention and its aqueous solutions exhibit a pH between 6 and 8 at 20 ° C. For the wood preservative of the invention more or 4 can be added as needed
