Embodiment 1

[0042] Embodiment 1: A wood and bamboo anticorrosion and anti-mold modification composition: comprising the following components by weight: 0.04 to 0.10 parts of triazole, 0.05 to 0.12 parts of iodopropynyl n-butyl carbamate ( IPBC), 1-6 parts of water-soluble dye, 1-6 parts of dyeing auxiliaries, 1-6 parts of flame retardant, and 1-10 parts of polymerization inhibitor.

[0043] The triazole is cyproconazole, propiconazole, tebuconazole, or a composition of propiconazole and tebuconazole in parts by weight of 1: 0.85-1.

[0044] The polymerization inhibitor is one or more combinations of polyethylene glycol, dipropylene glycol, diethylene glycol, and propylene oxide butyl ether.

[0045] The water-soluble dyes include one or more combinations of acid dyes, reactive dyes, direct dyes and basic dyes.

[0046] The dyeing auxiliaries include dicyandiamide, lignosulfonate, pinpina, alkyl fatty alcohol, sodium sulfite, nano-titanium dioxide, nano-zinc dioxide, nano-silica, nano-mon...

Embodiment 2

[0064] Embodiment 2: the preparation method of propiconazole / tebuconazole (PT) stock solution and PT / IPBC working solution:

[0065] Weigh 82g of 95% propiconazole and 68g of 97% tebuconazole into a 2000ml small reactor, add 320g of 95% ethanol, after dissolving propiconazole / tebuconazole, add 50g of 30% dodecyl Dimethyl ammonium oxide (OA-12) and 200g of 45% benzyl dodecyl dimethyl ammonium chloride, then add 70 g of 99% tetradecyl trimethyl ammonium chloride and 100 g of 70% ten Hexaalkyltrimethylammonium chloride, then add 137g distilled water, stir for 10 minutes, obtain water-soluble propiconazole / tebuconazole stock solution (PT), the mass fraction of tebuconazole / propiconazole is 14.0%, propiconazole The ratio of tebuconazole / tebuconazole is 1:0.85.

[0066] Weigh 101g of 99%IPBC in a 500ml small reaction kettle, add 400g of n-butanol, after the IPBC is dissolved, add 827g of 70% didecyldimethyl ammonium chloride, stir for 10 minutes with a stirrer, and the speed is 300...

Embodiment 3

[0068] Example 3 Preparation method of cyproconazole stock solution (Cy) and Cy / IPBC working solution:

[0069] Weigh 105g 95% cyproconazole into a 2000ml small reaction kettle, add 300g 95% ethanol, dissolve cyproconazole, add 24g 50% dodecyl dihydroxyethyl amine oxide (OAE-12) , then add 150g 45% benzyl dodecyl dimethyl ammonium chloride, finally add 65g 30% coco trimethyl ammonium chloride and 85g 99% tetradecyl trimethyl ammonium chloride and 16g distilled water , using a stirrer to stir for 10 minutes at a speed of 300-1000r / min. Then add 5 parts of water-soluble dye, 5 parts of dyeing auxiliaries, and 6 parts of flame retardant in parts by weight, heat, stir and fully mix. Dissolved into an aqueous solution to obtain a water-soluble cyproconazole stock solution (Cy), the mass fraction of cyproconazole in the Cy stock solution was 13.4%.

[0070] The preparation method of the Cy / IPBC composition working solution is the same as in Example 2.

Abstract

The invention belongs to a wood and bamboo material corrosion and mold prevention modified combination agent and a wood and bamboo material treating method. The wood and bamboo material corrosion andmold prevention modified combination agent comprises, by weight, 0.04-0.10 part of triazole, 0.05-0.12 part of 3-iodo-2-propynyl butylcarbamate, 1-6 parts of water soluble dyes, 1-6 parts of dyeing assistants, 1-6 parts of fire retardants and 1-10 parts of polymerization inhibitors. A wood and bamboo material treated through the modified combination agent can simultaneously have the functions of corrosion prevention, mold prevention, dyeing, inflaming retarding and pharmaceutical composition loss resistance, and has the advantages of easy operation, easy implementation, low preparation and using cost, good durability and long service life.

Description

technical field [0001] The invention belongs to an antiseptic and anti-mildew modified combination agent for wood and bamboo and a method for treating wood and bamboo. Background technique [0002] At present, among the main preservatives used in my country: CCA contains harmful heavy metals such as chromium and arsenic, which is highly toxic to humans and animals. The accumulated loss of solid waste and application process has potential harm to the environment, and its use has been banned or strictly restricted at home and abroad; Copper quaternary ammonium (ACQ) preservatives are severely corrosive to metals and have low antibacterial effects. When used, they require a higher drug loading and use costs are higher. [0003] Triazole fungicides are an important class of fungicides for crops, which inhibit the synthesis of ergosterol and affect the growth of mycelia and the formation of spores. Triazole fungicides mainly include tebuconazole (TEB), propiconazole (PPZ), cyproc...
