preparation example Construction

[0041] A preparation method for antibacterial and mildew-proof shell powder coating, comprising the following steps:

[0042] Step 1. According to the proportion, mix the deionized water, dispersant, wetting agent, defoamer, leveling agent, antifreeze, bactericide, and film-forming aid in the raw materials evenly to obtain a mixed liquid;

[0043] Step 2. According to the proportion, add antibacterial and antifungal agent, shell powder, heavy calcium carbonate, light calcium carbonate, titanium dioxide and beat at high speed to make the powder mix evenly to obtain a mixed slurry;

[0044] Step 3: Add emulsion, pH regulator and thickener according to the proportion and mix evenly to obtain the antibacterial and mildew-proof shell powder coating.

[0045] The preparation method of described antibacterial antifungal agent, comprises the following steps:

[0046] Step 1. Mix the molecular sieve and nano-zinc oxide evenly according to the proportion, and calcinate the obtained mix...

[0052] According to the formula quantity of this example, 3A molecular sieve and 13X molecular sieve were mixed with nano-zinc oxide evenly, calcined at 600° C. for 2.5 hours, and nano-zinc oxide was loaded on the molecular sieve at high temperature. After the calcined powder cools down, use a dry powder grinder to grind the powder for 1 hour, so that the calcined mixed powder I can be better mixed with other powders. Then mix the mixed powder I with nano-titanium dioxide, and calcine it at a temperature of 300°C for 4 hours. After the calcined powder cools down, use a dry powder mill to grind the powder for 0.5 hours, so that the calcined mixed powder II can be more Blends well with other powders. Finally, add bentonite, hydroxypropylmethylcellulose and hydroxyethylcellulose, mix in a powder mixer for 0.5h, and discharge to obtain an antibacterial and antifungal agent.

Abstract

The invention relates to an antibacterial and antifungal shell powder coating and belongs to technical field of interior wall coatings. The antibacterial and antifungal shell powder coating is prepared from deionized water, shell powder, emulsion, ground limestone, light calcium carbonate, titanium dioxide, antibacterial and antifungal agent and auxiliaries. The antibacterial and antifungal agentis prepared from molecular sieves, nano-zinc oxide, nanometer titanium dioxide, bentonite, hydroxypropyl methyl cellulose, and hydroxyethyl cellulose. The antibacterial and antifungal agent used in the antibacterial and antifungal shell powder coating is mostly prepared from inorganic materials, and the inorganic antibacterial and antifungal material has the characteristics of high safety, no volatility, good durability, no irritating odor, wide antimicrobial spectrum, no resistance to drugs, and good heat resistance and can have better and more durable antibacterial and antifungal effects onthe wall, causing no harm to the human body. Combined use of the antibacterial and antifungal agent in the coating and the shell powder avoids negative effects caused by organic antifungal bactericide, so that the coating is more environment-friendly and the antibacterial and antifungal effect is better and longer lasting.

Description

technical field [0001] The invention belongs to the technical field of interior wall coatings, in particular to an antibacterial and anti-mildew shell powder coating. Background technique [0002] In the field of building materials, interior wall paint is a kind of building material product used for painting and decoration of the interior walls of buildings. It is a necessary material for buildings, and its usage is huge. However, ordinary decorative paints are not suitable for some walls with special requirements, and sometimes even endanger health. [0003] In areas with relatively high air humidity, some harmful bacteria and molds are easy to breed on the surface of wall coatings. Long-term exposure to this environment will bring great harm to people's health, especially in some places that require strict control of bacteria and molds Environment, better antibacterial and anti-mildew is extremely important. [0004] Through the research on shell powder, it is found that...
