Description

A kind of composite wood anticorrisive agent and preparation method thereof

Technical field

The present invention relates to wood treatment agent technical field, specifically a kind of composite wood anticorrisive agent and preparation method thereof.

Background technology

Timber is a kind of natural organic, has obvious biological nature, easily by biological attack such as bacterium, worm, the raw boring in sea worms.Before use, according to different applied environments, select suitable anticorrisive agent, carry out appropriate process, then effectively can delay foxiness and extend woodwork service life etc., thus there is extremely important meaning.The timber preservative that current China commonly uses mainly contains: copper chromium arsenic (CCA), the molten alkylamine of ammonia (ammonia) copper (ACQ) and brass file (CA), because the arsenic chromium in CCA is all noxious material, easily human body is caused damage, especially during indoor use, larger to the harm of human body.In prior art, start by the efficient low toxic and environment-friendly anticorrisive agent such as ACQ, CA to replace CCA.Because single anticorrisive agent is narrow to wood preservation, scope that is fungi-proofing, mothproof, mildew-resistant, therefore Study and Development is a kind of efficiently, multifunctional novel composite wood anticorrisive agent is necessary, this not only can overcome weak point when single anticorrisive agent uses, but also can produce some new characteristics.

Summary of the invention

Composite wood anticorrisive agent that the object of the present invention is to provide a kind of anticorrosion, insect protected, mildew-resistant, sterilization and enhancing effective and preparation method thereof.

The technical solution adopted for the present invention to solve the technical problems is: a kind of composite wood anticorrisive agent, and its component by mass percent proportioning is: N-ethoxy ethamine triacetic acid 10% ~ 15%, eight Boratex 5% ~ 10%, Firebrake ZB 10% ~ 15%, nano titanium oxide 2% ~ 8%, Bravo 5% ~ 10%, isopropyl alcohol 10% ~ 15%, polyoxyethylate amide 1% ~ 3%, water 25% ~ 55%.

The particle diameter of described nano titanium oxide is in 1 ~ 100nm scope.

The preparation method of above-mentioned a kind of composite wood anticorrisive agent, comprises the following steps:

(1), each component is taken by weight ratio;

(2), N-ethoxy ethamine triacetic acid, eight Boratexes, Firebrake ZB, polyoxyethylate amide and water are added in agitator, 20 ~ 40min is stirred at 40 DEG C ~ 70 DEG C temperature, then nano titanium oxide is added, stir 20 ~ 30min, add Bravo and isopropyl alcohol again, make to continue stirring 15 ~ 20min together, to be mixed evenly after, be cooled to room temperature, obtain a kind of composite wood anticorrisive agent of the present invention.

The invention has the beneficial effects as follows, the present invention has good permeability, resistance leachability, and anticorrosion, insect protected, anti-mold effect are good, process timber are also had to the functions such as good enhancing, wear-resisting, long-acting nondiscolouring, thus there is very high practical value and popularizing application prospect.
