Problems solved by technology

This agent is highly toxic to humans, and the treated wood has reached its service life, which involves harmless treatment of the treated wood. CCA is very dangerous to the environment, and its use has been banned or strictly restricted at home and abroad.
The wooden components treated with the popular environmental-friendly protective agent quaternary ammonium copper (ACQ) have the following problems: 1. The preservative is mainly aimed at the anticorrosion of fungi, and has a certain inhibitory effect on wood beetles; 2. The wooden components can be used Lifespan, because copper does not degrade basically, the recycling of solid wood waste copper; 3. The color of the wood surface after ACQ t

Example Embodiment

[0028] Example 1

[0029] This embodiment provides an insect repellent and a preparation method thereof. The preparation method of the insect repellent is as follows:

[0030] Weigh 175g of 99% difenoconazole, 180g of 95% flusilazole, and 180g of 95% hexaconazole, place them in a 20L reactor, add 956g of 95% ethanol and 1148g of 99% DMF, After dissolving the difenoconazole / flusilazole / hexaconazole composition, add 1157g of 90% fenvalerate, 1195g of 50% calcium dodecyl dibenzene sulfonate and 1435g of 30% MOA -20,715g of water, use a stirrer to stir for more than 30 minutes, and the speed is more than 1000r per minute. After stirring evenly, an anti-insect antiseptic water emulsion is obtained, which is recorded as anti-insect agent A. The weight percentage composition of the components in the insect repellent A is: fenvalerate accounts for 14.6%, difenoconazole / flusilazole / hexaconazole accounts for 7.2%, ethanol and DMF account for 28.6%, dodecyl Calcium dibenzenesulfonate and M...

[0031] Example 2

[0032] This embodiment provides an insect repellent and a preparation method thereof. The preparation method of the insect repellent is as follows:

[0033] Weigh 175g of 99% difenoconazole, 185g of 95% flusilazole, 185g of 95% hexaconazole, and place them in a 20L reactor, add 717g of 95% ethanol and 861g of 99% DMF, After dissolving the difenoconazole / flusilazole / hexaconazole composition, add 970g of 90% fenvalerate, 875g of 50% calcium dodecyl dibenzene sulfonate and 1051g of 30% MOA -20,715g of water, use a stirrer to stir for more than 30 minutes, and the speed is more than 1000r per minute. After stirring evenly, an anti-insect antiseptic water emulsion is obtained, which is recorded as anti-insect agent B. The weight percentage composition of each component in the insect repellent B is: fenvalerate accounts for 15.2%, difenoconazole / flusilazole / hexaconazole accounts for 9.1%, ethanol and DMF account for 26.8%, dodecyl Calcium dibenzenesulfonate and MOA-...

Abstract

The invention provides an insect repellent, a preparation method thereof and the application of the insect repellent in the insect prevention of existing building wood components. The insect repellentis prepared from the following components: a triazole compound, fenvalerate, an organic solvent and a surfactant. The mass ratio of the triazole compound, the fenvalerate, the organic solvent to thesurfactant is (7 to 10) to (14 to 18) to (25 to 40) to (12 to 20), and the triazole compound is prepared by mixing difenoconazole, flusilazole and hexaconazole in a mass ratio of (0.9-1.1) : 1 : 1. The insect repellent provided by the invention not only has excellent insect-resist performance but also has an anti-corrosion function, and the fenvalerate and the triazole compound in the insect repellent have relatively good compatibility. In addition, when the insect repellent is used, the effective insect prevention and corrosion prevention of the wood components can be achieved under the condition that a drug loading capacity is small.

Description

technical field [0001] The invention belongs to the technical field of insect-proofing wood components, and relates to an insect-repelling agent, a preparation method thereof and an application in insect-proofing existing building wood components. Background technique [0002] As existing buildings, ancient buildings and folk houses are part of our country's traditional culture, and have extremely precious cultural relics and historical memories. In these existing buildings, various types of wooden components such as beams and columns are used. Wooden components are made of wood, which is vulnerable to attack and parasitism by pests. Common pests include wood beetle and powder beetle. Insect infestation is already one of the main causes of damage or disease of wooden components in existing buildings. The larvae of these pests burrow into the interior of the wood and eat away, creating dense, hollow burrows. In addition, due to the existence of holes, decaying bacteria can...
