Embodiment 1

[0037] 1.0% by weight of 2,4,5,6-tetrachloro-1,3-dicyanobenzene, 1.0% by weight of 3-iodo-2-propynylbutylcarbamate, 5% by weight The graft type quaternary ammonium salt cationic antibacterial agent (WS-8810) of fraction, the fatty alcohol polyoxyethylene ether (JFC) of 2% parts by weight, the styrylphenol polyoxyethylene ether (Nong milk 600 of 2% parts by weight) ) mixed with water of 84.95% by weight. The mixture is then fed into a disperser for dispersion. Wherein the rotating speed of the disperser is 1000 rpm, and the dispersion time is 45 minutes. If foaming occurs at this time, add 0.05% by weight of silicone defoamer. Then, after the mixture is uniformly dispersed, it is transferred to a sand mill for sand grinding. Wherein the rotating speed of sand mill is 1600 rev / mins, and sand mills 1 hour. After the sanding is completed, add 2% by weight of polyurethane thickener and 2% by weight of ethylene glycol, and evenly disperse to obtain the finished product of the wa...

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 ...
