Insect repellent, preparation method thereof and application of insect repellent in insect prevention of existing building wood components

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...

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 treatment is blue-green, and the color of the wood cannot be maintained; 4. ACQ has strong decay, and it will rot metal equipment parts during production. Severe, in the application, there is strong corrosion to the metal connecting reinforcements in the existing buildings

The single use of fenvalerate emulsion in water has a certain inhibitory effect on the microorganisms invading wood components, but it will not fundamentally prevent the growth and reproduction of microorganisms

If the wooden components are subjected to anti-corrosion treatment for the second time, not only the construction process is cumbersome, but also there will be problems such as compatibility between chemicals and cost.
