preparation example 1

[0039]The preparation of single-atom antibacterial disinfectant, step 1, the aqueous solution of 5g / L silver nitrate is added in the diatomite, wherein the mass ratio of transition metal salt and carrier is 1:20, the ultrasonic 30min dispersion is uniform under the condition of 100kHz of gained solution, Then the mixed solution was stirred at 100r / min for 12h;

[0040] Step 2, warming up the mixed solution obtained in step 1 to the boiling point of water, volatilizing at high temperature, evaporating the solvent, and fully grinding for 0.5 hours with a ball mill at a speed of 50 r / min to obtain a solid powder;

[0041] In step 3, the solid powder obtained in step 2 was heat-treated in an air atmosphere at 400° C. for 2 hours, cooled to room temperature, and ground by a ball mill at a speed of 50 r / min for 20 minutes to obtain the desired catalyst.

Embodiment 1

[0044] A single-atomic algae-killing and sterilizing pool coating, comprising the following components in weight percent: 23.5% deionized water, 2.5% polycarboxylate ammonium salt, 0.5% non-silicone mineral oil, 1.8% propylene glycol, 23% filler, olefin 1.5% polyurethane, 2% alcohol ester twelve, 40% ultra-fine styrene-acrylic emulsion, 0.2% dimethylethanolamine, 5% single-atom algicide; the filler is made of titanium dioxide, 3 % kaolin, 2% precipitated aluminum silicate composition.

[0045] A preparation method for single-atom algicidal and bactericidal pool coatings, comprising the following steps:

[0046] 1) In the selection of stainless steel Tietong, first add 14.5kg of deionized water, stirring at a speed of 300 rpm, under continuous stirring, add 2.5kg of polycarboxylate ammonium salt, 0.2kg of non-silicone mineral oil defoamer, 1.8kg propylene glycol, stir for 5 minutes to make all materials evenly mixed;

[0047] 2) Adjust the stirring speed to 500 rpm, slowly ad...

Embodiment 2

[0050] The difference between Example 2 and Example 1 is: 25.5% of deionized water, 42% of ultra-fine styrene-acrylic emulsion, 1% of single-atom algicide and bactericide in the single-atom algicidal and bactericidal pool coating formula, and other components are the same.

Abstract

The invention relates to the field of pool coatings, and specifically discloses a single-atom algicidal and bactericidal pool coating and a preparation method thereof. A single-atomic algae-killing and sterilizing pool coating, comprising raw materials in the following proportions: the product contains the following components in weight percentages: 20-30% deionized water, 2.0-3.0% dispersant, 0.2-1.0% defoamer, propylene glycol 1.5-2.5%, filler 20-35%, thickener 1.0-2.0%, film-forming aid 1.0-3.0%, ultra-fine styrene-acrylic emulsion 35-45%, pH regulator 0.1-0.5%, single-atom algicide Bactericide 1.0‑8.0%; its preparation method is: first add deionized water, add dispersant, defoamer, propylene glycol, filler, single atom algicide and bactericide under stirring, stir, grind, then add thickener, Deionized water, film-forming aids, ultra-fine styrene-acrylic emulsion, defoamer, and pH regulator are stirred to obtain a finished product. The invention is applied to the pool coating, and has the advantages of algae killing and anti-algae, antibacterial and anti-virus, and long-lasting purification.

Description

technical field [0001] The invention relates to the field of interior wall coatings, more specifically, it relates to a single-atom algicidal and bactericidal pool coating and a preparation method thereof. Background technique [0002] Water is the source of life, and the safe use of water resources is crucial to the survival and development of human beings. In daily life, common water algae such as green algae and cyanobacteria, and common water bodies such as Staphylococcus aureus, E. coli, H1N1 virus, and Salmonella cause disease Microorganisms seriously damage the ecological balance of water bodies, which in turn affects drinking water safety, water body sensory perception, aquaculture and other aspects. Traditional algae-killing and bactericidal chemicals have fatal defects such as high toxicity, short validity period, serious pollution, and non-recyclability. Therefore, the development of new, practical, and long-lasting algae-killing, anti-algae, anti-bacterial, and l...
