[0023] A green anti-mold insecticide for wood, made of the following raw materials in parts by weight: 65 sumac leaves, 61 Chinese pine leaves, 58 mountain peach stem bark, 52 catalpa leaves, 52 neem leaves, 48 ​​bark leaves, and 48 willow bark , hairy hazelnut 48, bellows fruit bark 43, white gun shaft 41, mountain akebia 37, knotwood stem bark 37, Bupleurum 37, purple ore seed 37, centipede 37, white sugar 8, gossypol 3, lactic acid bacteria 2, wine Yeast 2, compound enzyme 0.04.

[0024] For the gossypol, the cottonseed is crushed to 80 meshes, anhydrous ethanol with 5 times the weight of the cottonseed is added, placed at 43°C and 37kHz for ultrasonic extraction for 35 minutes, filtered to obtain the extract and filter residue, and then added to the filter residue 3 times A certain amount of absolute ethanol was placed at 46°C and 57 rpm for 32 minutes, filtered, and all extracts were combined, and placed at 42°C and 51 rpm for rotary evaporation until there was no ethanol...

Embodiment 2

[0039] A green anti-mold insecticide for wood, made of the following raw materials in parts by weight: sumac leaves 66, Chinese pine leaves 62, mountain peach stem bark 59, catalpa leaves 53, neem leaves 53, mulberry leaves 49, willow bark 49 , hairy hazelnut 49, bellows fruit bark 44, white gun shaft 42, mountain akebia 39, knotwood stem bark 39, Bupleurum 39, purple ore seeds 39, centipede 39, white sugar 9, gossypol 4, lactic acid bacteria 3, wine Yeast 3, compound enzyme 0.05.

[0040]For the gossypol, the cottonseed is crushed to 100 mesh, anhydrous ethanol of 6 times the weight of the cottonseed is added, placed at 44°C and 38kHz for ultrasonic extraction for 38 minutes, filtered to obtain the extract and filter residue, and then 4 times the weight of the cottonseed is added to the filter residue A certain amount of absolute ethanol was placed at 47°C and 58 rpm for 33 minutes, filtered, and all extracts were combined, and placed at 43°C and 52 rpm for rotary evaporation...

Embodiment 3

[0055] A green anti-mold insecticide for wood, made of the following raw materials in parts by weight: 67 sumac leaves, 63 Chinese pine leaves, 60 mountain peach stem bark, 54 catalpa leaves, 54 neem leaves, 50 bark leaves, and 50 willow bark , hairy hazelnut 50, bellows fruit bark 45, white gun shaft 43, mountain akebia 41, knotwood stem bark 41, Bupleurum 41, purple ore seed 41, centipede 41, white sugar 10, gossypol 5, lactic acid bacteria 4, wine Yeast 4, compound enzyme 0.06.

[0056] For the gossypol, the cottonseed is crushed to 100 mesh, and anhydrous ethanol 7 times the weight of the cottonseed is added, placed at 45°C and 39kHz for ultrasonic extraction for 40 minutes, filtered to obtain the extract and filter residue, and then 5 times the weight of the cottonseed is added to the filter residue A certain amount of absolute ethanol was placed at 48°C and 59 rpm for 34 minutes, filtered, and all extracts were combined, and placed at 44°C and 53 rpm for rotary evaporati...

Abstract

The invention relates to the technical field of wood processing and discloses a green mould-proof insecticide for wood materials. The green mould-proof insecticide is prepared from the following raw materials: cotinus coggygria leaves, Chinese pine leaves, mountain peach bark, catalpa leaves, melia azedarach leaves, paper mulberry leaves, periploca bark, corylus mandshurica, physocarpus monogynus bark, fraxinus malacophylla, clematis finetiana, edgeworthia chrysantha bark, Chinese thorowax root, butea monosperma seeds, centipedegrass, white granulated sugar, gossypol, lactic acid bacteria, wine yeasts and compound enzymes. The raw materials are rich and cheap, are simple to prepare, are green and healthy, are free of any toxic reagent, are friendly to the environment, and are harmless to the human body. Steamer water is reserved and used for extracting and can prevent mould, kill insects, increase flexibility and facilitate processing; and at the same time, water usage can be saved, the environment can be protected, and the cost can be saved by 10.2%. Through the double fermentation of the lactic acid bacteria and the wine yeasts, plant cell structures are destroyed, the extracting of effective components is promoted, small-molecular antibacterial components are increased, the mould-proof and insecticidal effect is enhanced, the antibacterial rate reaches 81.7%, and the insecticidal rate reaches 78.3%.

Description

technical field [0001] The invention mainly relates to the technical field of wood processing, in particular to a green anti-mold insecticide for wood. Background technique [0002] Wood antifungal insecticides are a class of chemical agents that inhibit or prevent fungi, insects, and marine borers from growing and multiplying in wood. Antiseptic treatment of wood can prolong the storage and service life of wood products, reduce the demand for wood, and is an important way to protect forest resources. [0003] At present, organic phosphorus compounds commonly used in the market as wood mildew-proof insecticides include copper chromium arsenic (CCA), ammonia-soluble alkylamine (ammonia) copper (ACQ) and copper file (CA), because organic phosphorus compounds can paralyze Nerves, arsenic and chromium in CCA are toxic substances, which are easy to cause damage to the human body. In the process of production and use, they cause great harm to the human body. Therefore, the market...
