Preparation method of wood preservative containing copper element

Abstract

The invention discloses a preparation method of a wood preservative containing copper elements. The preparation steps of the preservative are as follows: 1), dissolving propiconazole, tebuconazole and cyproconazole in at least one organic solvent, adding Dodecyl benzyl dimethyl ammonium chloride (BAC), double octaalkyl dimethyl ammonium chloride, make it dissolve completely, make triazole solution, 2), in reactor, add water earlier, then Quickly add copper salt, stir, then slowly add monoethanolamine and 20% ammonia water, stir while adding, control the adding speed to prevent the violent reaction from spraying out, when the copper salt is completely dissolved, cool to 50-80°C, and prepare Obtain copper amine [ammonia] complex, 3), add copper amine [ammonia] complex in the triazole solution at last, stir evenly, make copper azole wood preservative; The present invention has good stability, strong loss resistance, The usage amount is small, the method is simple and practical, no heating is required for preparation, and the production cost is low.

Description

technical field [0001] The invention relates to a preservative, in particular to a preparation method of a copper-containing wood preservative. Background technique [0002] Wood is a biopolymer material, which is easily harmed and degraded by biological factors such as fungi and insects, such as decay and insects. Wood preservatives can overcome this defect. For wood used under outdoor conditions, copper preservatives are effective after treating wood. The fixation performance of ingredients in wood is an important factor to determine its antiseptic and insect-proof effect. The ACQ preservative wood after antiseptic treatment will have mildew during storage before leaving the factory, and it will have serious damage to metal during use. Corrosion effect, which not only has a corrosion effect on the anti-corrosion treatment equipment, but also causes corrosion hazards to the wood structure and wood member metal fasteners during the factory use of ACQ anti-corrosion wood.

[0002] Wood is a biopolymer material, which is easily harmed and degraded by biological factors such as fungi and insects, such as decay and insects. Wood preservatives can overcome this defect. For wood used under outdoor conditions, copper preservatives are effective after treating wood. The fixation performance of ingredients in wood is an important factor to determine its antiseptic and insect-proof effect. The ACQ preservative wood after antiseptic treatment will have mildew during storage before leaving the factory, and it will have serious damage to metal during use. Corrosion effect, which not only has a corrosion effect on the anti-corrosion treatment equipment, but also causes corrosion hazards to the wood structure and wood member metal fasteners during the factory use of ACQ anti-corrosion wood. The large ratio of triazole to copper leads to the use of triazole The amount is high, the cost is high, and the use of ammonia to partially or completely replace monoethanolamine increases the corrosion resistance of the metal. In addition, adding a small amount of phosphate has the disadvantages of poor preparation stability and precipitation.
