Problems solved by technology

Quaternary ammonium antibacterial agents also have certain toxicity, while chitosan and its derivatives, sorbic acid, etc. are not strong enough to kill bacteria, so it is not recommended to add them to interior wall coatings
[0004] Patent CN1045308043A discloses a kind of environment-friendly thermal insulation building coating containing styrene-acrylic emulsion, hydroxyethyl cellulose and chitosan, etc., which has antibacterial effect, but as mentioned above, the bactericidal ability of natural antibacterial agents such as chitosan not strong enough
Patent CN104449165A, CN104387856A, CN104387859A, CN104371436A, CN103834242A all disclose the interior wall latex paint that contains hydroxyethyl cellulose, styrene-acrylic emulsion and / or acrylate emulsion, antifungal agent and / or bactericide, and these interior wall coatings all have Anti-mildew and / or bactericidal effects, but they all use organic anti-fungal agents and / or fungicides, which are not environmentally safe and have certain toxicity
[0005] Patent CN102304305A discloses a formaldehyde-removing coating containing persimmon skin extract, which can also inhibit bacteria and remove formaldehyde, but the content of persimmon skin extract in the coating is relatively large, and the cost is high, and because the active ingredients in the extract are easy to volatilize , the antibacterial persistence of the coating is not enough

preparation example Construction

[0044] Preparation example of plant-based composite nano-bactericidal powder

[0045] Wash and slice the fresh leaves, branches and roots of camphor trees, cedar, pine needles, arborvitae and purslane, and conduct infrared radiation heating for rapid dehydration and drying. Carry out nano-grinding production technology for grinding and crushing to obtain nano camphor tree powder, nano cedar powder, nano pine needle powder, nano arborvitae powder, and nano purslane powder with nano-scale particle size. These nanoscale plant bactericidal powders are then mixed in proportions by weight shown in Table 1 to make corresponding plant-based composite nano bactericidal powders. The particle size of the nanopowder is also shown in Table 1.

Embodiment 1

[0049] Prepare the plant sterilization and insect repellent functional type white interior wall latex paint by the formula weight part of table 2, comprise the following steps:

[0050] a) Prepare raw materials according to the weight parts set by the formula, put hydroxyethyl cellulose, purified water, additives, antifreeze, titanium dioxide, plant-based nano-bactericidal powder, and fillers into the container in turn and stir at high speed at 1400-1600 rpm Minutes, after stirring evenly, grind on a horizontal sand mill until the fineness is less than or equal to 30 μm, then transfer it to a mixing container, reduce the speed to 800 rpm, add polymer emulsion, film-forming aids, fluid Leveling agent, adding thickener to adjust the viscosity required by customers.

[0051] b) Detection-filter-package-sample retention.

Embodiment 2

[0053] The adjustment of the formula ratio of this embodiment is shown in Table 2. The specific implementation process is basically the same as that of Example 1, the only difference being that the high-speed stirring speed is 1200-1400 revolutions per minute, and the stirring time is 30 minutes.

Abstract

The invention discloses a plant-sterilizing and insect-repelling functional interior wall latex paint and a preparation method thereof. The interior wall latex paint comprises the following components by weight: 120-150 parts of polymer emulsion, 3-5 parts of hydroxyethyl cellulose, 2-5 parts of plant-based composite nano-bactericide powder, 15-25 parts of antifreeze, and 7-9 parts of film aid, 3-6 parts of thickener, 3-5 parts of leveling agent, 180-220 parts of filler, 350-450 parts of water. The present invention adjusts the formula structure and adds plant-based composite nano-bactericidal powder, wherein the component plant-based composite nano-bactericidal powder is dehydrated by infrared dehydration technology and nano prepared by production technology. The bactericidal powder is a green, environmentally friendly, and healthy bactericidal material, which is non-toxic and harmless to the human body. The interior wall latex paint of the present invention is low in cost, bactericidal, antibacterial, anti-mildew, and insect repellent are efficient and durable, with strong practicability and wide application prospects. .

Description

technical field [0001] The invention relates to the technical field of interior wall latex paint, and particularly discloses a plant-sterilizing and insect-repelling functional interior wall latex paint and a preparation method thereof. Background technique [0002] Viruses and bacteria exist everywhere in our living environment, which pose a threat to human health; in addition, pests such as mosquitoes, flies, cockroaches, fleas, bedbugs and mites can spread diseases and affect people's health. In this regard, humans are also constantly developing sterilization and deworming technology. For example, there is a technical branch of antibacterial coatings in the coatings industry. [0003] Antibacterial agents in antibacterial coatings are usually inorganic antibacterial agents such as silver ions, organic antibacterial agents such as quaternary ammonium antibacterial agents, natural antibacterial agents such as chitosan and its derivatives, sorbic acid, etc. Although silver...
