Embodiment 1

[0019] Use nano-silver antibacterial agent as the first layer, press 100g / m 2 Spray evenly on the base surface of the synthetic leather, and dry it at 50°C; then mix the nano-silver antibacterial agent and polyurethane in a mass ratio of 1:1 as the second layer, and press 80g / m 2 Spray evenly on the base surface of the synthetic leather, and dry it at 50°C; use pure polyurethane resin as the third layer at 50g / m 2 The amount is uniformly sprayed onto the base surface of the synthetic leather, then placed on the condition of 50°C for drying, and finally ironed once at 100°C under a pressure of 70Kg to obtain antibacterial non-natural leather.

Embodiment 2

[0021] Use nano silver as the first layer, according to 110g / m 2 The amount is evenly sprayed onto the base surface of the artificial leather, and placed at 55°C for drying; then the nano-silver antibacterial agent and polyacrylic resin are mixed in a mass ratio of 1:10 as the second layer, and the weight is 90g / m 2 Spray evenly on the base surface of the artificial leather, and dry it at 55°C; use pure polyacrylic resin as the third layer at 60g / m 2 The amount is evenly sprayed onto the base surface of the artificial leather, then placed on the condition of 50°C for drying, and finally ironed once at 100°C under a pressure of 70Kg to obtain antibacterial non-natural leather.

Embodiment 3

[0023] Use nano-zinc oxide as the first layer, according to 120g / m 2 Spray evenly on the base surface of the microfiber leather, and dry it at 55°C; then mix nano-zinc oxide and butadiene resin in a mass ratio of 1:20 as the second layer, and weigh 100g / m 2 Spray evenly on the base surface of the microfiber leather, and place it at 60°C for drying; use pure butadiene resin as the third layer at 70g / m 2 Spray evenly on the base surface of the microfiber leather, then dry it at 55°C, and finally iron it once at 100°C under a pressure of 70Kg to obtain an antibacterial non-natural leather.

Abstract

The invention discloses a sandwich treatment method of antibacterial non-natural leather. The sandwich treatment method comprises the following steps of (1) using a certain amount of an antibacterial agent as a first layer, spraying to the substrate surface of the non-natural leather, and drying the treated non-natural leather at the temperature of 50 to 60 DEG C; (2) mixing the antibacterial agent and resin according to a certain ratio, using a certain amount of a mixed solution as a second layer, spraying to the substrate surface of the non-natural leather obtained in step (1), and drying at the temperature of 50 to 60 DEG C; (3) using a certain amount of resin as a third layer, spraying to the substrate surface of the non-natural leather obtained in step (2), and drying at the temperature of 50 to 60 DEG C; then, ironing at the temperature of 100 DEG C and pressure of 70Kg, so as to obtain the antibacterial non-natural leather. The sandwich treatment method has the advantages that the finished product of non-natural leather can be treated, the suitability is wide, the practicality is strong, the operation is simple and convenient, and the prepared antibacterial non-natural leather has a good antibacterial property and an antibacterial lasting property.

Description

technical field [0001] The invention belongs to the technical field of preparation of antibacterial functional materials, and in particular relates to a "sandwich" treatment method of antibacterial non-natural leather. Background technique [0002] Non-natural leather is a combination of synthetic resin and base fabric in a certain way, which can partially or completely replace the appearance and performance of natural leather, including synthetic leather, artificial leather and microfiber leather. Among them, synthetic leather is based on non-woven fabric, mainly using polyurethane as resin, and the imitation leather obtained after film processing has a smooth surface, uniform physical properties such as color, strength, thickness, etc., and its wind resistance, The water resistance is better than that of natural leather; artificial leather is mainly a mixture of polyvinyl chloride resin (PVC), plasticizer, stabilizer, etc., which is a kind of leather-like plastic product o...
