Embodiment 1

[0028] The first step is the preparation of nano-silver coated with modified starch, the method is as follows:

[0029] (1) the silver nitrate solution of preparation 0.05mol / L and the sodium citrate solution that concentration is 1% are subsequent use;

[0030] (2) Add 50ml of water into the three-necked flask, then add 0.25g of modified starch, turn on the heat-collecting constant temperature heating magnetic stirrer, put the above three-necked flask into it, stir and heat up to 95°C for about 30min to gelatinize the starch;

[0031] (3) Lower the temperature to 70°C, add dropwise 10ml of the prepared silver nitrate solution into the three-necked flask, and continuously stir for 10 minutes;

[0032] (4) Add 2ml of the prepared sodium citrate solution dropwise at a rate of 1 drop / s, and stir to make it fully react;

[0033] (5) After the color of the reaction system no longer changes, that is, after the reaction is sufficient, the prepared sol is taken out from the reaction ...

Embodiment 2

[0038] The first step is the preparation of nano-silver coated with modified starch, and its preparation steps and process are the same as in Example 1.

[0039] The second step is to prepare nano-silver three-proof antibacterial finishing agent according to the optimization results of each component, as follows: (1) according to nano-silver sol: HS1100:ATB9800:TPM9007=0.3:7:2:3, weigh 3g of nano-silver sol , HS1100 three-proof finishing agent 70g, ATB9800 antibacterial finishing agent 20g, TPM9007 antibacterial finishing agent 30g (total liquid weight 1000g)

[0040] (2) First place 70g of HS1100 three-proof finishing agent in a three-necked flask with stirring, then gradually add 3g of nano-silver sol, 20g of ATB9800 antibacterial finishing agent, 30g of TPM9007 antibacterial finishing agent, and add water to a total liquid weight of 1000g.

[0041] (3) Stir the compounded three antibacterial agent at normal temperature and pressure for 10 minutes until it is uniform.

Embodiment 3

[0043] The first step is the preparation of nano-silver coated with modified starch, and its preparation steps and process are the same as in Example 1.

[0044] The second step is to prepare nano-silver three-proof antibacterial finishing agent according to the optimization results of each component, as follows: (1) according to nano-silver sol: HS1100:ATB9800:TPM9007=0.4:8:3:3, weigh 4g of nano-silver sol , HS1100 three-proof finishing agent 80g, ATB9800 antibacterial finishing agent 30g, TPM9007 antibacterial finishing agent 30g (total liquid weight 1000g)

[0045] (2) First place 80g of HS1100 three-proof finishing agent in a three-necked flask with stirring, then gradually add 4g of nano-silver sol, 30g of ATB9800 antibacterial finishing agent, 30g of TPM9007 antibacterial finishing agent, and add water to a total liquid weight of 1000g.

[0046] (3) Stir the compounded three antibacterial agent at normal temperature and pressure for 10 minutes until it is uniform.

Abstract

The invention discloses a nano silver tri-proof antibacterial finishing agent and a preparation method thereof. The nano silver tri-proof antibacterial finishing agent is prepared from nano silver antibacterial sol coated by modified starch, a tri-proof finishing agent HS1100, an antibacterial finishing agent ATB9800 and an antibacterial finishing agent TPM9007 according to a weight ratio of 0.1-0.4:5-9:2-5:2-4. Naturally degradable polymer-starch is used as a protective agent and a dispersing agent, and the nano silver sol coated by the starch is prepared by adopting a simple liquid-phase chemical reduction method, so that the nano silver tri-proof antibacterial finishing agent is simple in process, environment friendly, high in dispersity and less prone to aggregation. The nano silver tri-proof antibacterial finishing agent prepared by the method can be used for one-bath finishing, and is simple in process and convenient to operate compared with split-bath finishing.

Description

[0001] This application is a divisional application with application number: 201410606498.6, application date: 2014.10.31, and name "nano-silver three-proof antibacterial finishing agent and its preparation method". technical field [0002] The invention relates to a preparation method of a nano-silver three-proof antibacterial finishing agent. Background technique [0003] With the improvement of people's quality of life, single-function textiles are increasingly unable to meet people's needs. In some special occasions, there are more requirements (such as waterproof, oil-proof, anti-fouling, anti-ultraviolet, anti-static, antibacterial properties, etc.) ), which makes the development of multifunctional textiles more and more people's attention. At present, the three-proof antibacterial finishing generally adopts the three-proof antibacterial separate bath finishing, that is, the first three-proof and then the anti-bacterial finishing or the first anti-bacterial and then th...
