Embodiment 1

[0017] The configuration mass percentage is 0.05% thiophanate-methyl + 0.05% carbendazim + 0.50% didecyldimethylammonium chloride anti-blue stain and anti-mold liquid: thiophanate-methyl is 70% wettable powder 0.3g , Carbendazim is 50% wettable powder 0.3g, didecyl dimethyl ammonium chloride is 98% solution 3g, add water to make 600g anti-mold liquid, stir evenly. Masson pine raw material 100mm×20mm×20mm, planed, without drying, treated by cold soaking method, soaking time 10-20min, stacked according to conventional methods, naturally dried, placed indoors, can achieve long-term anti-blueing and anti-mildew effect bacteria effect.

Embodiment 2

[0019] The configuration mass percentage is 0.05% thiophanate-methyl + 0.05% carbendazim + 0.50% didecyldimethylammonium chloride anti-blue stain and anti-mold liquid: thiophanate-methyl is 70% wettable powder 0.3g , Carbendazim is 50% wettable powder 0.3g, didecyl dimethyl ammonium chloride is 98% solution 3g, add 75% alcohol to make 600g anti-mold liquid. The solvent is alcohol, thiophanate-methyl and carbendazim have a better dissolution effect, and the anti-blue stain and anti-mildew solution configured has a more significant control effect. The masson pine raw wood is 100mm×20mm×20mm, without drying, treated by cold soaking method, soaking time for 10-20min, stacked according to conventional methods, dried naturally, and placed indoors, which can achieve long-term anti-blueing and anti-mildew antibacterial effect.

Embodiment 3

[0021] The configuration mass percentage is 0.10% thiophanate-methyl + 0.10% carbendazim + 1.00% didecyldimethylammonium chloride anti-blue stain and anti-mold liquid: thiophanate-methyl is 70% wettable powder 0.6g , carbendazim is 0.6g of 50% wettable powder, didecyl dimethyl ammonium chloride is 6g of 98% solution, add water to make 600g of anti-mold liquid, and stir evenly. Masson pine raw material 100mm×20mm×20mm, planed, without drying, treated by cold soaking method, soaking time 10-20min, stacked according to conventional methods, naturally dried, placed indoors, can achieve long-term anti-blueing and anti-mildew effect bacteria effect.

Abstract

The invention relates to a blue stain and mildew preventing processing method for masson pine timber. The method comprises the steps of: agitating 0.05-0.15% of thiophanate-methyl, 0.05-0.15% of carbendazim and 0.50-1.00% of double alkyl chain quaternary ammonium salt, with a solvent which is water or 75% alcohol uniformly to prepare a blue stain and mildew preventing liquid for masson pine timber; then quenching the masson pine timber naturally dried by the blue stain and mildew preventing liquid for masson pine timber for 10-20min; or processing fresh pine by way of painting or spraying, naturally drying the fresh pine and spraying for 2-3 times, and then stacking the masson pine timber processed by the blue stain and mildew preventing liquid for masson pine timber in an open type and naturally drying. The method provided by the invention can effectively inhibit propagation of various blue-stain fungi and moulds on the masson pine timber, has remarkable antibacterial effect and is simple in operational process with low processing cost, low using concentration of insecticide and low toxicity.

Description

technical field [0001] The invention relates to a method for anti-corrosion of masson pine wood, in particular to a treatment method for anti-blueing and anti-mildew of masson pine. Background technique [0002] Masson pine is the main timber tree species in southern my country with high economic value. It is the main material for civil engineering, furniture, interior decoration, industrial packaging and so on in my country. However, during the storage process, masson pine wood is extremely susceptible to blue stain and mold infection, causing the wood to discolor. Although the wood discoloration fungus will not cause the decay of the wood, it will turn the wood black, green or blue, leading to the pollution of the wood surface, seriously reducing the quality of the wood, affecting its appearance, and causing serious economic losses. At present, the successful technology of preventing the blue discoloration of wood in production mainly relies on chemical agent treatment. ...
