Embodiment Construction

[0016] The antibacterial coating provided by the embodiment of the present invention includes a powder material, a sizing agent, a water resistance agent, a dispersant, and a pH regulator, wherein the powder material includes a pigment and an antibacterial component.

[0017] The pigment can be selected from one or more of calcium carbonate, kaolin, clay, aluminum hydroxide, titanium dioxide, and talcum powder. Considering fluidity and coating cost, heavy calcium carbonate and light calcium carbonate are preferred as the main components of the pigment.

[0018] The antibacterial component includes at least chitosan, titanium dioxide and silver zeolite in the present invention. The reason why the above three antibacterial ingredients are used in combination is mainly based on economical and practical considerations: although the antibacterial effect of silver zeolite is good, it is expensive, and the dosage should not be too high; chitosan antibacterial agent is more safe , bu...

Abstract

The invention relates to an antibacterial coating which comprises a powder material, an alkyl ketene dimer or modified alkyl ketene dimer, an ammonium zirconium carbonate anti-hydration agent, a dispersing agent and a pH regulator, wherein the powder material comprises pigment and antibacterial components; the antibacterial components at least include chitosan, titanium dioxide and silver zeolite; in the powder material, the content of chitosan is 5-10% by mass, the content of titanium dioxide is 30-45% by mass, and the content of silver zeolite is 0.5-1.0% by mass; the addition amount of the alkyl ketene dimer or modified alkyl ketene dimer is 0.2-1.0% of the total mass of the powder material; the addition amount of the ammonium zirconium carbonate anti-hydration agent is 0.5-1.5% of the total mass of the powder material; the addition amount of the dispersing agent is 0.5-0.65% of the total mass of the powder material; the addition amount of the pH regulator is within a limit where the pH value of the antibacterial coating is 8.5-9.5. The cost of the antibacterial coating is low, and the antibacterial effect is stable. The invention also relates to an antibacterial paper.

Description

technical field [0001] The invention relates to an antibacterial paint and antibacterial paper. Background technique [0002] With the development of society and the improvement of people's living standards, in order to meet the needs of their own health, people have higher and higher hygienic requirements for working and living environments, thus promoting the development of various antibacterial products, among which antibacterial paper is also one of them. . [0003] Antibacterial paper not only requires the necessary quality characteristics of general paper products, but also requires better antibacterial effect. However, the antibacterial paper currently on the market has the following defects: due to the water absorption and swelling characteristics of the paper, the moisture in the air or the environment can easily infiltrate into the paper, and the microorganisms in the air or the environment can easily penetrate into the paper, thereby Cause the antibacterial effe...
