Long-acting insect expelling and purifying functional coating as well as preparation method and construction method thereof

Abstract

The invention belongs to the technical field of building materials, and particularly relates to a long-acting insect expelling and purifying functional coating and a preparation method and a construction method thereof. The coating consists of a coating A and a coating B, wherein the coating A is prepared from the following raw materials in percentage by mass: 15 to 25 percent of talcum powder, 18to 25 percent of ground calcium carbonate, 8 to 15 percent of shell powder, 12 to 20 percent of ash calcium powder, 5 to 8 percent of bentonite, 1 to 3 percent of rubber powder, 2 to 6 percent of lemon eucalyptus alcohol, 1 to 4 percent of a pyrethrin agent, 5 to 10 percent of folium artemisiae argyi powder, 2 to 5 percent of lemongrass powder, and 2 to 4 percent of natural perfume; and the coating B is prepared from the following raw materials in percentage by mass: 85 to 95 percent of a basic paint, 2 to 8 percent of hexacyclic stone, 2 to 5 percent of germanite and 1 to 5 percent of infrared ceramic powder. The coating integrates insect expelling and air purification functions, has the characteristics of environmental friendliness, health, long-acting effect, durability, nature, high efficiency, sanitation, disease prevention, energy conservation and emission reduction, and can improve the living environment for people; and the preparation method and the construction method are simple and feasible.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a long-acting insect-repelling and purifying functional coating, a preparation method and a construction method thereof. Background technique [0002] Mosquitoes, cockroaches, fleas and other pests not only have a great impact on the environmental sanitation and physical health of human living space, but also can spread diseases such as malaria, filariasis, plague, Japanese encephalitis, dengue fever and other serious infectious diseases. In addition to physical blocking methods such as screen windows, screen doors, and mosquito nets, insecticidal aerosols and mosquito-repellent incense are mainly used to kill mosquitoes and flies. [0003] Insecticidal aerosols have serious pollution to the living room environment, especially to the health of children, pregnant women, and the elderly. Carcinogenicity, aroma molecules in fragrances and O 3 (ozone) reacts ...

Problems solved by technology

Among them, CN 201510915970.9 uses realgar AS 2 S 3 As an insect repellant, it is a highly toxic substance and is not safe to use

[0006] Although the above-mentioned Chinese herbal medicine mosquito repellent latex paint has good environmental performance, a core problem is that the time limit is too short. According to the product test disclosed in the above patent, it will generally have a good effect within 25-40 days at room temperature in summer. After 60 days, the function basically disappears. The reasons are: the slow-release control and the latex paint film-forming coating carrier are too small, and the depth of the release carrier is lacking.

[0007] General latex paint coating wall area 6.0m2 2 / kg or so, the solid content of latex paint is about 50%, which is equivalent to 80g / m 2 , the thickness of the paint film is 30-40um, that is, 0.03-0.04mm, therefore, the aging time is short, and it lacks the value of promotion and application
