Embodiment 1
[0033] 70 mL of THF, 1 gram of water anhydrous carbonate, 12.2 grams of hexapoxymethyl methadeide, N. 2 Protect the next room temperature for 12 h. After the phase transfer catalyst TbAb was added, the stirring was mixed, and a THF 50 ml of THF 50 ml of THF 50 ml of Trichloronitrile was added to the flask, and the reaction was stirred at room temperature and then warmed to the reflux reaction after 72 h. Naturally fell to room temperature, retained, after removing the solvent, was sufficiently washed with deionized water until the aqueous solution was neutral, and the product was placed at a vacuum drying tank at 60 ° C for 15 h to give a white powder compound. The white powder was dissolved in 50 mL of distilled water, and 3.6 g of zinc acetate was added, stirred to zinc acetate completely dissolved, slowly drop with 4 mol / L sodium hydroxide solution, and added to the precipitate after dissolution; add graphene 0.5g, Then, the polyacrylamide (4 million molecular weights of 4 mi...
Embodiment 2
[0041] Nano-zinc oxide rod / graphene / polyphosphorne in Example 1.
[0042] Preparation of antiviral, antibacterial flame retardant cloth:
[0043] S31. Place the chemical fiber textile fabric in an alkaline solution having a concentration of 5 to 25% by weight and is soaked in 0.5 to 50 min;
[0044] S32. The fabric processed via the step S31 is soaked in the slurry for 10 to 60 min;
[0045] S33. Dry the fabric after soaking step S32;
[0046]Among them, the slurry in step S32, according to the weight percentage, including: 5 to 45 wt% nano-zinc oxide / graphene / polyphosphoryonl derivative, 3 to 25 wt% coupling agent, 3 ~ 25 wt% emulsifier, 10 ~ 55 wt% of the two-pro-organic solvent. The coupling agent is KH550, the emulsifier is the tray-80, and the two 亲 邮 邮 is ethylene glycol.
[0047] According to GB / T 21866-2008, the anti-gold-yellow staphylococcal rate is> 99.99%, anti-E. coli ratio is> 99.99%, anti-white candida ratio> 99.9%, anti-copper green fake single cyclospori...
Embodiment 3
[0049] Nano-zinc oxide rod / graphene / polyphosphorne in Example 1.
[0050] Preparation of antiviral, antibacterial flame retardant cloth:

[0052] S32. The fabric processed via the step S31 is soaked in the slurry for 10 to 60 min;
[0053] S33. Dry the fabric after soaking step S32;
[0054] Among them, the slurry in step S32, according to the weight percentage, including: 5 to 45 wt% nano-zinc oxide / graphene / polyphosphoryonl derivative, 3 to 25 wt% coupling agent, 3 ~ 25 wt% emulsifier, 10 ~ 55 wt% of the two-pro-organic solvent. The coupling agent is KH550, the emulsifier is the tray-80, and the two 亲 邮 邮 is ethylene glycol.
[0055] According to GB / T 21866-2008, the anti-gold-yellow stapcleis ratio is> 99.99%, anti-E. coli ratio is> 99.99%, anti-white candida ratio> 99.9%, anti-copper green fake single cyclos...
