[0035] The defoamer is Corning's A10.

[0036] Titanium dioxide is rutile titanium dioxide produced by the chloride method, which is BLR-895;

[0037] The filler is a combination of three types of calcined kaolin, diatomite, and heavy calcium carbonate; the calcined kaolin is calc...

Embodiment 2

[0051] The difference between embodiment 2 and embodiment 1 is: the natural plant extract liquid mosquito repellent and anti-insect health care coating comprises the following components by weight:

[0052]

[0053] The filler is calcined kaolin; the calcined kaolin is calcined kaolin DB80 from Shanxi Jinyang.

[0054] The preparation method of the above-mentioned natural plant extract mosquito repellent and insect-proof health care coating comprises the following steps:

[0055](1) According to the above parts by weight, first soak the peeled neem seeds in ethanol with 5 times the weight of the peeled neem seeds for 6 hours, then in the above ethanol, use a high-speed blade to cut, stir and pulverize to extract azadirachtin, and then filter , to obtain the extract and filter cake, and finally the extract was concentrated in vacuum at no more than 40°C to remove ethanol to obtain a concentrate containing azadirachtin, which was set aside.

[0056] (2) According to the abov...

Embodiment 3

[0062] The difference between embodiment 3 and embodiment 1 is: a kind of natural plant extract of the present invention repelling mosquitoes and insects health care paint, comprises the following components by weight:

[0063]

[0064]

[0065] The filler is heavy calcium carbonate; the heavy calcium carbonate is heavy calcium carbonate CC-800 from Jiangxi Guangyuan.

[0066] The preparation method of the above-mentioned natural plant extract mosquito repellent and insect-proof health care coating comprises the following steps:

[0067] (1) According to the above parts by weight, first soak the peeled neem seeds with ethanol with 4 times the weight of the peeled neem seeds for 9 hours, then in the above-mentioned ethanol, use a high-speed blade to cut, stir and pulverize to extract azadirachtin, and then filter , to obtain the extract and filter cake, and finally the extract was concentrated in vacuum at no more than 40°C to remove ethanol to obtain a concentrate contai...

Abstract

The invention discloses a mosquito-repellent and insect-resistant health coating with a natural plant extraction solution and a preparation method thereof, and relates to the technical field of coatings. The mosquito-repellent and insect-resistant health coating is prepared from the following components in parts by weight: 50-70 parts of waterborne synthetic resin emulsion, 10-25 parts of filler, 0.1-0.5 part of wetting agents, 0.2-0.4 part of dispersants, 0.2-0.6 part of defoaming agents, 5-10 parts of natural plant extraction solution, 2-10 parts of plant essential oil, 10-30 parts of deionized water, 100-250 parts of titanium dioxide, 0.2-1 part of thickening agents, 0.3-0.8 part of flatting agents, 0.1-0.3 part of pH regulators and 0.1-0.15 part of film forming additives, wherein the natural plant extraction solution is an azadirachta indica plant extraction solution. The coating has the characteristics that the coating is capable of efficiently repelling mosquitoes and resisting insects and is free of pollution to people and surrounding environments, and effective components of the plant extraction solution are slowly released in the coating and exert the effects for a long time.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a mosquito-repelling and insect-repelling health care coating with natural plant extracts and a preparation method thereof.
