Problems solved by technology

[0003] However, in the traditional copper azole preparations, the solubility of triazole in water is extremely small, and it is easy to precipitate. After the wood is treated, the fixation amount of its active ingredients is small, which affects its antiseptic and insecticidal effect.

Embodiment 1

[0018] A copper triazole wood preservative, characterized in that the preservative is made of the following parts by weight of raw materials:

[0019]

[0020] The invention also provides a preparation method of the copper triazole wood preservative, which is characterized in that it comprises the following steps:

[0021] (1) Prepare raw materials according to the weight ratio;

[0022] (2) Prepare the triazole solution first: Dissolve the required amount of flusilazole, difenoconazole, and cyproconazole in isopropanol, add dodecyl dimethyl benzyl ammonium chloride and diphosphate Ammonium hydrogen to completely dissolve the triazole compound, then add imidacloprid to make a triazole solution;

[0023] (3) Preparation of copper ammonia complex: first add water to the reactor, quickly add copper isothiazoline and copper citrate, stir, then slowly add ammonia water, stir while adding, control the adding speed to prevent the reaction from violent reaction After the copper salt is compl...

Abstract

The invention discloses a copper triazole wood antiseptic agent and a preparation method thereof and belongs to the field of corrosion prevention for wood. The copper triazole wood antiseptic agent is prepared from, by weight, 7%-15% of kathon 886, 7%-15% of copper citrate, 2%-4% of flusilazole, 1%-3% of difenoconazole, 1%-3% of cyproconazole, 2%-4% of dodecyl dimethyl benzyl ammonium chloride, 2-4% of ammonium dihydrogen phosphate, 0.5%-2% of imidacloprid, 5%-10% of sodium tetraborate, 20%-30% of isopropanol, 10%-20% of ammonium hydroxide and the balance water. The antiseptic agent has the advantages of being good in durability and stability, not prone to loss, high in permeability, high in safety, small in harmful damage to wood, and the like. After the wood is subjected to anti-corrosion treatment, the mechanical strength, good texture and pleasant color and luster of the wood are not affected.

Description

Technical field [0001] The invention relates to the field of wood preservatives, in particular to a copper triazole wood preservative and a manufacturing method thereof. Background technique [0002] Wood preservative treatment can improve the durability of wood. Compared with the traditional wood preservative CCA (chromated copper arsenate), copper azole preservatives are more environmentally friendly. Compared with ACQ preservatives, copper azole treatment has a lower dosage and lower cost. Copper Azole CA (Copper Azole) preservative is a wood preservative composed of divalent copper, azolane compound, ammonia or amine and water in a certain proportion. It was admitted to the American AWPA standard in 1995. CA preservatives do not contain arsenic, chromium and other organic pollutants, and do not contain harmful VOCs that may pollute indoor air. They are generally used substances. Among them, the copper azole CA-B wood preservative is a mixture of divalent positively charged ...
