Problems solved by technology

[0003] Cement mortar and Portland concrete are used for the walls and floors of buildings, which are easy to absorb water. Humid air will make wood products and mortar objects corroded by termites, so people often spray anti-termite drugs on the places where they may appear or on the surface of objects. , but once the drug gets wet, it will reduce its efficacy or even fail
In addition, mica powder, aluminum powder, graphite and glass beads are used as fillers in the damping coating, which has the disadvantage of high cost and high energy consumption
[0004] In the southern region, due to the humid climate, wood products and mortar in buildings with high humidity or water are most likely to be eaten by termites. Termites can also eat plastics, wires and cables, and steel bars in concrete. Harm, will greatly shorten the service life of the home improvement project

preparation example Construction

[0035] The preparation method of the described insecticide-containing micropod suspension may further comprise the steps:

[0036] Mix the protective colloid, emulsifier, water and lye to obtain a mixed aqueous phase;

[0037] Fly ash, permethrin, phoxim and terephthaloyl chloride are mixed with an organic solvent to obtain a mixed organic phase;

[0038] The mixed organic phase and the mixed water phase are emulsified, and then an aqueous solution of ethylenediamine is added to carry out interfacial polymerization reaction to obtain a microcapsule suspension containing insecticide.

[0039] In the above preparation process, the fly ash is used as the carrier of the microcapsules, which has a porous structure and can be loaded with insecticides to achieve a slow-release effect; at the same time, it can enhance the sound-absorbing effect of the damping coating and increase the loss coefficient; the microcapsules have The structure includes a capsule core and a capsule wall, an...

Embodiment

[0048] The preparation process of anti-termite damping coating is divided into two parts:

[0049] 1) The first part is to prepare microcapsule suspensions containing insecticides: it includes the following components: permethrin and phoxim insecticides are used as capsule cores, and terephthaloyl chloride and ethylenediamine are suspensions of capsule walls , the mass ratio of core wall is 1:4, sodium hydroxide is used as acid binding agent, emulsifier op-10, polyvinyl alcohol is used as protective colloid; the preparation process is as follows:

[0050] Water phase preparation: add a certain amount of polyvinyl alcohol and OP-10 in distilled water, stir evenly, add a certain amount of sodium hydroxide solution, and the stirring speed is 1000-1200 rpm;

[0051] Organic phase preparation: Dissolve fly ash powder, permethrin, phoxim and terephthaloyl chloride in organic solvent carbon tetrachloride, mix and stir evenly, and the stirring speed is 500-1000 rpm;

[0052] Emulsifi...

Abstract

The invention provides a damping coating for preventing termites. The damping coating is prepared from 20 to 28 weight percent of matrix resin, 15 to 20 weight percent of inorganic filler, 5 to 10 weight percent of wood fiber, 15 to 25 weight percent of waste rubber powder, 5 to 10 weight percent of microcapsule suspension containing insecticide and 5 to 15 weight percent of water. The damping coating for preventing termites, which is provided by the invention, has the characteristics of termite prevention, good chemical stability, controllable release speed, good damping effect, low cost and the like.

Description

technical field [0001] The invention relates to the metal field of paint compositions, in particular to a damping paint for termite prevention. Background technique [0002] Noise can be seen everywhere in our lives, and it has a huge impact on people's life and health, and it can cause hearing loss, gastric dysfunction, and sympathetic system tension and other adverse effects. Vibration is the source of noise, and there are two main ways to reduce vibration: vibration isolation and damping. The latter is to paint or spray a layer of damping paint on the vibrating thin plate, and convert one energy (mechanical vibration) into other energy (thermal energy) for dissipation, which is the damping technology. Nowadays, water-based damping coatings are widely used, which are composed of emulsions, inorganic fillers and functional additives; among them, the research on emulsions is mainly about the blending, copolymerization, hyperbranching and core-shell structure modification of...
