Abstract
An antiseptic for wood is prepared from borate, bithiocyanomethane, and ethanediol through heating and stirring until full dissolving.
Description
Affiliated technical field
The present invention relates to anticorrisive agent, more particularly the present invention relates to a kind of timber preservative and preparation method thereof, it is applicable to the wood protection of indoor and non-loss condition (through waterproof finish).
Background technology
As everyone knows, timber is human natural material with the most use since ancient times, the decorative pattern beauty, and ratio of strength to weight height, therefore processing easily be subjected to liking of people always, especially is used widely in furniture manufacturing and building material industry.Yet it is the infringement that is easy to be subjected to worm, bacterium that timber also has the shortcoming of a maximum, rotten, mouldy, makes the application of timber be subjected to very big restriction.In order to solve the protection question of timber, prior art often adopts copper chromium arsenic (CCA) and two kinds of timber preservatives of quaternary ammonium copper (ACQ), these two kinds of anticorrisive agents have antiseptic effect preferably, but deficiency is to need vacuum pressed to handle just can reach insect protected, corrosion-resistant result of use.In addition, treated timber band green, and contain the heavy metal copper ion, unsuitable indoor use can only be used for the open air.Some other medicament can not be used widely because of complex process, poor permeability, factor such as cost an arm and a leg.Therefore, how anticorrosion still can not get so far solves indoor timber preferably, and this is the prior art weak point just.
Summary of the invention
The objective of the invention is to solve the problem that existing timber preservative is unsuitable for indoor wood protection, provide a kind of and not only can be used for the open air, and be specially adapted to timber preservative of the wood protection under the indoor and non-loss condition and preparation method thereof.
Timber preservative of the present invention is made up of borate, dithiocyano-methane and ethylene glycol, and its weight percentage is:
Borate 20～60%
Dithiocyano-methane 0.1～0.5%
Ethylene glycol 39.5～79.5%
The preparation method of this timber preservative is as follows: ethylene glycol is added in the stirred vessel, add borate again, stirred vessel is heated to 100～110 ℃ of also continuous stirrings to be dissolved fully up to borate, add dithiocyano-methane then, continuation is heated and is stirred, and dissolves fully up to dithiocyano-methane to get final product.
In above-mentioned invention scheme, described borate can be eight boric acid disodium or sodium pentaborates.
The prescription preferred weight percent scope of preparation timber preservative of the present invention is:
Borate 33～55%
Dithiocyano-methane 0.2～0.4%
Ethylene glycol 44.8～66.8%
The optimum formula percentage by weight of timber preservative of the present invention is:
Borate 40%
Dithiocyano-methane 0.3%
Ethylene glycol 59.7%
The present invention adopts borate to be because borate is a kind of good anticorrisive agent, and its good penetrability has the insect protected function again.And dithiocyano-methane is the mould inhibitor of using always, and borate and dithiocyano-methane are combined, and makes solvent and makes timber preservative and have well anticorrosion and vermins-proof effect with ethylene glycol.Material source of the present invention is abundant, and manufacture method is simple, uses very conveniently, is painted on the timber or timber soaked and get final product.In addition, timber preservative of the present invention does not contain heavy metal ion, and colorless and odorless can not pollute environment, and is safe in utilization, can be widely used in indoor furniture, and indoor hardware fitting etc. also can be used for outdoor gardens, building etc. under non-loss condition.
Boratory content is high more, and its anticorrosion and vermins-proof effect is comparatively obvious, but too highly then can't dissolve, too low anticorrosion, vermins-proof effect is not obvious.
Dithiocyano-methane content surpasses then dissolving difficulty more than 0.5% less than not reaching anti-mold effect below 0.1%.
Ethylene glycol is as lytic agent, and the purpose that heats in whipping process is to quicken the dissolving of borate and dithiocyano-methane.
The specific embodiment
The constituent content of this timber preservative has embodiment as shown in the table:
| Embodiment | Borate (%) | Dithiocyano-methane (%) | Ethylene glycol (%) | |
| Eight boric acid disodiums | Sodium pentaborate | |||
| 1 | 40 | 0.3 | 59.7 | |
| 2 | 60 | 0.1 | 39.9 | |
| 3 | 20 | 0.5 | 79.50 | |
The preparation method of this timber preservative is as follows:
With embodiment 1 is example, 5970 gram ethylene glycol are added in the stirred vessel, add 4000 grams, eight boric acid disodiums again, stirred vessel is heated to 100～110 ℃, after constantly being stirred to eight boric acid disodiums and dissolving fully, add two sulphur cyanogen methane, 30 grams then, continuation heating and stirring are dissolved fully until dithiocyano-methane and are got final product.
Claims (5)
1. timber preservative and preparation method thereof is characterized in that this timber preservative is made up of borate, dithiocyano-methane, ethylene glycol, and the weight percentage of each component is:
Borate 20～60%
