Embodiment 1

[0075] The water-soluble fungicide spraying application process prepared by embodiment 1:

[0076] Prepare working solution:

[0077] 1% water soluble fungicide

[0078] the rest is water

[0079] Spray directly on the surface of artificial leather and dry at 80°C.

[0080] The application effect is shown in Table 2 in detail. According to GJB150.10A-2009 to detect mold resistance (grade), it is grade 2; according to GB / T3920-2008 to detect color fastness to rubbing (grade), it is grade 4; according to GB / T 8427-2008 to detect color fastness to light (Grade) is grade 4; according to GB / T 8949-2008 detection of anti-adhesion (grade), it is grade 4.

[0081] Among them, GJB150.10 A-2009 uses 5 levels to assess the mold resistance level of test samples: Level 0 - no mold growth on the material; level 1 - scattered, rare or very limited mold growth; level 2 - mold spread intermittently on the surface of the material Either the colony is loosely distributed, or there is a cont...

Embodiment 5

[0092] The water-soluble antifungal agent brush coating application process prepared by embodiment 5:

[0093] Prepare working solution:

[0094] 4% water soluble fungicide

[0095] 3% cationic polyurethane emulsion

[0096] the rest is water

[0097] Put the prepared working solution into the working tank, pad the artificial leather with the working solution, and dry it at 100°C. Bake at 160°C for 2 minutes.

[0098] The application effect is shown in Table 2 in detail. According to GJB150.10A-2009 to detect mold resistance (grade), it is grade 2; according to GB / T3920-2008 to detect color fastness to rubbing (grade), it is grade 4; according to GB / T 8427-2008 to detect color fastness to light (Grade) is grade 4; according to GB / T 8949-2008 detection of anti-adhesion (grade), it is grade 4.

[0099] It shows that it is excellent in antibacterial and anti-mildew, not only has the effect of anti-bacterial and anti-mildew, meets the requirements of environmental protection...

Abstract

The invention relates to a preparation method of an antibacterial and antifungal material for artificial leather, in particular to an antibacterial and antifungal material for artificial leather and apreparation method thereof. The antibacterial and antifungal material comprises, by weight, 30-50% of 1.8% octylamine acetate, 0.5-1% of Zhongshengmycin, 0.2-0.6% of flocuxacin, 5-8% of sodium diacetate, 5-10% of quaternary ammonium salt cationic surfactant, 1-3% of penetrant, 2-5% of dispersion emulsifier, 2-5% of sodium hexametaphosphate and the balance water. The invention also provides the preparation method. The prepared antibacterial and antifungal material for the artificial leather has an antibacterial and antifungal effect, meets environmental protection requirements and also can improve the softness and surface color fastness of the artificial leather.

Description

technical field [0001] The invention relates to the technical field of antibacterial and antifungal materials, in particular to a preparation method of an antibacterial and antifungal material for artificial leather. [0002] technical background [0003] Artificial leather is a kind of leather-like product with appearance and feel similar to natural leather, which is soft and wear-resistant. After the artificial leather is used for a long time, its luster will deteriorate and its softness will also decrease. If it encounters humid weather, it will become moldy, which will affect the service life of the artificial leather. At present, most of the antifungal agents for artificial leather are added to the coating slurry during the production of artificial leather, and are mainly solvent-based. Such as invention patent application CN108677546A a kind of artificial leather and its preparation method, the main components of the selected raw materials are Kathon, paraben, organic ...
