Embodiment 1

[0032] First, 40 parts of isothiazolinone with a mass concentration of 10% and 500 parts with a concentration of 16×10 -5 The g / mL nano-silver colloidal solution is stirred and mixed at room temperature to make a compound antibacterial agent, and then the compound antibacterial agent is first sprayed on the grain surface and meat surface of the cowhide mat that has been conventionally coated with the bottom layer and middle layer with a back cover effect After drying, the spraying amount is 320g / m 2 ;The grain surface of the cowhide mat sprayed with the compound antibacterial agent was screed, the pressure was 10MPa, the temperature was 70°C, and the screed time was 2s; finally, the obtained cowhide mat was followed by conventional top coating and embossing treatment That's it.

Embodiment 2

[0034] First, 30 parts of mass concentration of 12% isothiazolinone and 450 parts of concentration of 14 × 10 -5 The g / mL nano-silver colloidal solution is stirred and mixed at room temperature to make a compound antibacterial agent, and then the compound antibacterial agent is first sprayed on the grain surface and meat surface of the cowhide mat that has been conventionally coated with the bottom layer and middle layer with a back cover effect After drying, the spraying amount is 350g / m 2 ;The grain surface of the cowhide mat sprayed with the compound antibacterial agent was screed, the pressure was 15MPa, the temperature was 66°C, and the screed time was 2s; finally, the obtained cowhide mat was followed by conventional top coating and embossing treatment That's it.

Embodiment 3

[0036] First, 20 parts of isothiazolinone with a mass concentration of 1.5% and 400 parts with a concentration of 8×10 -5 The g / mL nano-silver colloidal solution is stirred and mixed at room temperature to make a compound antibacterial agent, and then the compound antibacterial agent is first sprayed on the grain surface and meat surface of the cowhide mat that has been conventionally coated with the bottom layer and middle layer with a back cover effect After drying, the spraying amount is 270g / m 2 ;The grain surface of the cowhide mat sprayed with the compound antibacterial agent is screed, the pressure is 5MPa, the temperature is 68°C, and the screed time is 1s; finally, the obtained cowhide mat is subjected to subsequent conventional top coating and embossing treatment That's it.

Abstract

The invention discloses a cow leather mat with an anti-bacterial function. The cow leather mat is characterized in that a grain side and a flesh side of the cow leather mat simultaneously comprises a nano-silver and isothiazolinone antibacterial agent; the inhibition zone of the nano-silver and isothiazolinone antibacterial agent to staphylococcus aureus, colon bacillus, bacillus subtilis, Aspergillus niger, blue mould, hair mould, cryptococcus neoformans, candida albicans is 43.28 to 68.84mm; the dry wipe resistance level is 4 to 5 level or 5 level; the wet wipe resistance level is 3 to 4 level or 4 level; and folding resistance fastness is 1 level. The invention also discloses a preparation method of the cow leather mat. The cow leather mat not only has good inhibit function to bacterium and fungus, but also has durable antibacterial property; the preparation method is skillful, the only thing to do is to add antibacterial treatment after a middle layer is coated, additional investment cannot be increased, the process is simple to operate, and the cow leather mat is applicable to industrial application.

Description

technical field [0001] The invention belongs to the technical field of functional leather products and their preparation, and in particular relates to a cowhide mat with antibacterial function and a preparation method thereof. Background technique [0002] Cowhide mats were a traditional product in southeastern Sichuan before the 1950s. Because of their incomparable advantages in natural leather, such as good air permeability and water vapor permeability, sweat absorption, summer coolness, and durability, they are popular among consumers. favorite. [0003] As a processed product of leather collagen protein, cowhide mats contain oils (such as fatliquors), sugars (such as tannins) and other ingredients in the raw and auxiliary materials used in the leather processing process, making it a bacteria and fungi. Good source of nutrients for growth. In addition, the sweat left by people on the leather, the dust and moisture in the air will also accelerate the growth of bacteria a...
