Problems solved by technology

In addition, the current antibacterial ingredients in coatings are isothiazolinones, benzoimidazoles, formaldehyde sustained-release agents, etc. These antibacterial agents can effectively kill bacteria, but they are irritating to the skin, and the addition amount has strict requirements. And it will slowly decompose over time

preparation example Construction

[0034] A kind of preparation method of plant environment-friendly mildew-resistant and antibacterial paint, concrete steps are as follows:

[0035] Step S1: Add water, hydroxyethyl cellulose, and pH adjuster in order to disperse for 2-4 minutes at a speed of less than 600 rpm in the reaction kettle;

[0036] Step S2: Keep the speed of the reaction kettle constant, add natural plant antibacterial and antifungal agents, and disperse for 2-5 minutes;

[0037] Step S3: Increase the speed of the reactor to 600-1000rpm, add water-based wetting agent, water-based dispersant, defoamer, titanium dioxide, calcined kaolin, calcium carbonate, diatomaceous earth, and ultrafine zinc oxide in sequence, and increase the speed of the reactor To 1200-1500rpm, disperse for 15-25min;

[0038] Step S4: Adjust the rotation speed of the reaction kettle to 700-1000 rpm, add emulsion, antifreeze, and film-forming aid in sequence and continue stirring for 10-15 minutes to obtain a finished product.

Embodiment 1

[0043] Adjust the speed of the reaction kettle to 500rpm, add 28 parts of water, 0.4 part of hydroxyethyl cellulose, 0.5 part of water-based dispersant, 0.2 part of water-based wetting agent, 1 part of natural plant antibacterial and anti-fungal agent, 0.2 part of water-based defoamer, and Increase the speed of the reaction kettle to 1000rpm, add 18 parts of titanium dioxide, 9 parts of kaolin, 15 parts of calcium carbonate, 13 parts of diatomaceous earth, and 2 parts of ultrafine zinc oxide, continue to increase the speed of the reaction kettle to 1300rpm, and stir for 20min. After mixing evenly, reduce the speed of the reactor to 1000rpm, continue to add 22 parts of emulsion, 0.5 part of antifreeze, 0.8 part of film-forming aid, and 0.3 part of water-based defoamer, and stir for 15 minutes to obtain this product.

Embodiment 2

[0045]Adjust the speed of the reaction kettle to 600rpm, add 30 parts of water, 0.4 parts of hydroxyethyl cellulose, 0.5 parts of water-based dispersant, 0.2 parts of water-based wetting agent, 1.5 parts of natural plant antibacterial and anti-fungal agent, and 0.2 parts of water-based defoamer. Increase the speed of the reaction kettle to 900rpm, add 16 parts of titanium dioxide, 8 parts of kaolin, 13 parts of calcium carbonate, 15 parts of diatomaceous earth, and 1.5 parts of ultrafine zinc oxide, continue to increase the speed of the reaction kettle to 1300rpm, stir for 15 minutes, and mix After uniformity, reduce the speed of the reactor to 1000 rpm, continue to add 23 parts of emulsion, 0.5 part of antifreeze, 0.8 part of film-forming aid, and 0.3 part of water-based defoamer, and stir for 12 minutes. Get this product.

Abstract

The invention relates to a plant environment-friendly mildew-proof antibacterial coating and a preparation method thereof. Theo antibacterial coating is prepared from the following raw materials: water, hydroxyethyl cellulose, a water-based dispersing agent, a pH regulator, a water-based wetting agent, a natural plant antibacterial mildew-proof agent, titanium dioxide, calcined kaolin, calcium carbonate, diatomite, superfine zinc oxide, emulsion, an anti-freezing agent, a coalescing agent and a water-foaming agent. According to the invention, natural plant components are used for mould prevention and antibiosis, and in addition, the addition of a superfine zinc oxide powder can not only synergistically perform mould prevention and antibiosis, but also efficiently remove indoor formaldehyde, so that the effect of purifying the indoor environment is realized together; and natural plant components and inorganic nano materials are used for mildew prevention, antibiosis and formaldehyde removal, so that the coating is healthier and more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a plant-friendly anti-mildew and anti-bacterial coating and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of the social economy and the continuous improvement of living standards, people have higher requirements for the quality of life. The rise of interior decoration has caused a series of air pollution problems, which has attracted widespread attention. [0003] Decoration materials such as boards and adhesives used in the decoration of new houses, as well as newly purchased furniture and cabinets, are often sources of formaldehyde. In addition, the current antibacterial ingredients in coatings are isothiazolinones, benzoimidazoles, formaldehyde sustained-release agents, etc. These antibacterial agents can effectively kill bacteria, but they are irritating to the skin, and the addition amount has strict requirement...
