Antifungal and antibacterial agent for waterproof leather product and preparation method of antifungal and antibacterial agent

Abstract

The invention relates to an antifungal and antibacterial agent for a waterproof leather product and a preparation method of the antifungal and antibacterial agent. The antifungal and antibacterial agent for the waterproof leather product comprises the following components in percentage by weight: 1-6.5 percent of antifungal agent, 2-5 percent of antibacterial agent, 1-4 percent of penetrating agent, 1-4 percent of dispersion emulsion, 1-3 percent of thickening agent, 2-5 percent of anti-freezing agent, 0.05-0.1 percent of antifoaming agent and the balance of solvent. By adopting the antifungal and antibacterial agent for the waterproof leather product and the preparation method of the antifungal and antibacterial agent, provided by the invention, an efficient, low-toxicity, convenient (soaking, padding or direct spraying), water soaking-resistant and water washing-resistant antifungal effect can be achieved. In the antifungal and antibacterial agent for the waterproof leather product, a grafted quaternary ammonium salt cation antibacterial agent is added and can be organically combined with the leather product for forming a layer of antibacterial film on the surface of the leather product, so that an excellent water-resistant antibacterial effect is achieved.

Description

technical field [0001] The invention relates to leather products, more specifically, to a water-resistant leather product anti-mildew and antibacterial agent and a manufacturing method thereof. Background technique [0002] Leather products contain a lot of nutrients such as collagen, which is the best source of nutrition for mold and bacteria. When the leather products are in an environment with an ambient temperature of 25-35 degrees Celsius and a relative air humidity of 75-95%, mold is very easy to grow, and mild mildew affects the appearance of leather products, making the grain surface of leather products lose luster; Mildew stains may cause mildew on the grain surface of leather products, intestinal cracking, and significantly reduce the physical and mechanical properties of leather products, seriously affecting the sales and performance of leather products. [0003] In the prior art, there are many antifungal agents for preventing leather products from growing mold ...

AI Technical Summary

Problems solved by technology

When the leather products are in an environment with an ambient temperature of 25-35 degrees Celsius and a relative air humidity of 75-95%, mold is very easy to grow, and mild mildew affects the appearance of leather products, making the grain surface of leather products lose luster; Mildew stains may cause mildew on the grain surface of leather products, intestinal cracking, and significantly reduce the physical and mechanical properties of leather products, seriously affecting the sales and performance of leather products

[0003] In the prior art, there are many antifungal agents for preventing the growth of mold and bacteria on leather products, but their effects are not ideal

Because its anti-mildew mechanism relies on the leaching and migration of the drugs applied on the surface of leather products to kill or inhibit the growth of mold to achieve the anti-mildew effect, the effective time is very limited

And when the leather products are wetted or further soaked in water, the antifungal agent will be dissolved in the water, causing it to completely lose the antifungal effect

[0004] In addition, the antifungal agents in the prior art generally do not contain antibacterial components, which cause bacteria to multiply and grow rapidly on leather products, causing great harm to the health of users
