Embodiment 1

[0018] A kind of raw material and weight of organic water-soluble fungicide for MDF: thiophanate-methyl 0.01g, propiconazole 0.1g, tebuconazole 0.1g, didecyldimethylammonium chloride 5g, organic solvent 10g of ethanolamine, 10g of organic solvent ethanol, and 74.79g of water.

[0019] Preparation:

[0020] Add 0.1g of propiconazole to 10g of organic solvent ethanolamine to dissolve, stir evenly, then add 0.1g of tebuconazole and 10g of organic solvent ethanol in turn, stir evenly, so that propiconazole and tebuconazole are fully dissolved to make solution A;

[0021] Mix 0.01g of thiophanate-methyl and 5g of didecyldimethylammonium chloride, add 74.79g of water, and stir evenly, so that thiophanate-methyl and didecyldimethylammonium chloride are fully dissolved to prepare Solution B;

[0022] The obtained solution A is mixed with the solution B, and stirred evenly to prepare an organic water-soluble antifungal agent for medium density fiberboards.

Embodiment 2

[0024] A kind of raw material and weight of organic water-soluble fungicide for MDF: 0.05g thiophanate-methyl, 0.5g propiconazole, 0.5g tebuconazole, 10g didecyldimethylammonium chloride, organic solvent Ethanolamine 10g, organic solvent ethanol 10g, water 68.95g.

[0025] Preparation:

[0026] Add 0.5 g of propiconazole to 10 g of organic solvent ethanolamine to dissolve, stir evenly, then add 0.5 g of tebuconazole and 10 g of organic solvent ethanol in sequence, stir evenly, so that propiconazole and tebuconazole are fully dissolved, and make solution A;

[0027] Mix 0.05g of thiophanate-methyl and 10g of didecyldimethylammonium chloride, add 68.95g of water, and stir evenly, so that thiophanate-methyl and didecyldimethylammonium chloride are fully dissolved to prepare Solution B;

[0028] The obtained solution A is mixed with the solution B, and stirred evenly to prepare an organic water-soluble antifungal agent for medium density fiberboards.

Embodiment 3

[0030] A kind of raw material and weight of organic water-soluble fungicide for MDF: 0.05g thiophanate-methyl, 0.5g propiconazole, 0.5g tebuconazole, 10g didecyldimethylammonium chloride, organic solvent 20g of ethanolamine, 20g of organic solvent ethanol, and 48.95g of water.

[0031] Preparation:

[0032] Add 0.5 g of propiconazole to 20 g of organic solvent ethanolamine to dissolve, stir evenly, then add 0.5 g of tebuconazole and 20 g of organic solvent ethanol in sequence, and stir evenly, so that propiconazole and tebuconazole are fully dissolved to make solution A;

[0033] Mix 0.05g of thiophanate-methyl and 10g of didecyldimethylammonium chloride, add 48.95g of water, and stir evenly, so that thiophanate-methyl and didecyldimethylammonium chloride are fully dissolved to prepare Solution B;

[0034] The obtained solution A is mixed with the solution B, and stirred evenly to prepare an organic water-soluble antifungal agent for medium density fiberboards.

Abstract

The invention discloses an organic water-soluble antifungal agent for medium-density fiberboard and a preparation method thereof. 0.1-1.0%, didecyldimethylammonium chloride 5-25%, organic solvent ethanolamine 10-25%, organic solvent ethanol 10-25%, and the balance is water. The invention is a water-borne organic wood antifungal agent, which does not contain metal elements, has a low dosage of fungicide, has obvious drug effects, has the characteristics of high efficiency, broad spectrum, stability and environmental protection, and can be treated by soaking, brushing, spraying and other methods Density fiberboard has good anti-mildew effect, rational use of wood resources, and good economic, social and ecological benefits.

Description

technical field [0001] The invention belongs to the field of wood protection, and relates to an organic water-soluble antifungal agent for medium-density fiberboards and a preparation method thereof. Background technique [0002] As a renewable resource, wood is one of the important raw materials in my country's national economic construction. However, wood is a natural biomass material. There are various microorganisms in nature, which cause the deterioration of wood and its products. During the process of growth and storage, discoloration and decay will occur, which will increase the color difference and greatly reduce the physical and mechanical properties. Disintegrate its structure, thereby reducing the utilization rate of wood and limiting the scope of application. This kind of microbial destruction consumes 1 / 10 of wood and its products every year, resulting in a lot of waste of resources. Board products are also susceptible to microbial attack. At present, fiberboa...
