Description

An ultra-long nano-silver wire/lignin synergistic antibacterial and antistatic gloves and its preparation method

technical field

The invention belongs to the field of glove preparation, in particular to an ultra-long nano-silver wire/lignin synergistic antibacterial and antistatic glove and a preparation method thereof.

Background technique

Silver has good antibacterial properties, high safety, low toxicity to mammals and few complications, good persistence, and achieves the purpose of lasting antibacterial. Nano-silver can inhibit the growth and spread of most bacterial species, such as Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and other pathogenic bacteria, as well as fungi such as dermatophytes and more than 650 kinds of pathogenic bacteria. Bacteria can even kill HIV-1, and bacteria treated with silver ions are basically unable to survive, which prevents bacteria from developing drug resistance.

At the same time, nano-silver itself has good conductivity, which can effectively eliminate the harm of static electricity to the human body, eliminate the discomfort caused by static electricity when the human body moves or puts on and takes off, and expands the application of the prepared gloves.

Contents of the invention

The invention provides an ultra-long nano-silver wire/lignin synergistic antibacterial and antistatic glove, and each component includes:

In the present invention, on the basis of the ultra-long nano-silver wire as an antibacterial material, by adding lignin to play a catalytic role, the silver wire can enter the bacterial cells, so that the antibacterial effect of the silver wire is effectively improved; and the nano-lignin itself cannot enter the bacterial cells.

Among them, plasticizers are polyester plasticizers, mainly including W2500, UN-615, Ultramoll Ⅳ (4), W8000, W-2050, which have good compatibility with polymer materials, low volatility, and oil resistance. And resistance to the extraction of aliphatic or aromatic hydrocarbons, excellent migration resistance, aging resistance and high temperature resistance, etc.

Acrylic resin is a "core-shell" structure copolymer, such as ACR-401, ACR122U-A9, ACR-ZB-20, P-551J, ACR-ZB-401, which can effectively reduce the plasticizing temperature of PVC resin, Improve the processing performance of PVC, reduce the amount of plasticizer,

Stabilizers are potassium-zinc stabilizers, sodium-zinc stabilizers, magnesium-calcium-zinc stabilizers, etc., which prevent the catalytic degradation of HCl by capturing the HCl generated by the thermal decomposition of PVC; and dehydrochloride the hydrogen chloride generated by the thermal decomposition of PVC from the matrix again The formed conjugated double bond has an addition effect, inhibits the growth of the conjugated chain, and effectively prevents the degradation of PVC.

The dispersant is an efficient polymer hyperdispersant, such as Solsperse 3000, Solsperse13650, Solsperse22000, Solsperse 5000, etc.

Surfactants refer to fixed hydrophilic and lipophilic groups that can effectively improve the surface morphology of PVC emulsions, mainly alcohol ethers, alkanolamides, sodium dodecylsulfonate, nonylphenol polyoxyethylene ether, ZWP One or a mixture thereof;

The aspect ratio of the ultra-long nano-silver wire is 100-1000, and the diameter is 10-50nm; the nano-lignin is the unrefined conventional lignin with a particle diameter of 10-20nm;

The coupling agent is mainly to improve the dispersion of nano-silver wire and lignin in the matrix resin, the uniformity of the glove appearance and the stable performance. The present invention mainly adopts fluorine-containing silane coupling agent, such as trifluoropropylmethylethylene Based polysiloxane, heptadecafluorodecyltriethoxysilane fluorosilane, etc., on the one hand, can improve the dispersion of silver nanowires and lignin in the matrix, on the other hand, fluorine-containing coupling agents Coupling agent, the coupling performance is more stable, and can improve the corrosion resistance of gloves.

The present invention also provides a preparation method of the above-mentioned ultra-long nano-silver wire/lignin synergistic antibacterial and antistatic gloves: stirring and mixing each component into a paste, filtering, vacuuming, and standing still, then putting it into the production line trough ; After impregnating the paste with an 80°C glove mold for 100 seconds (the paste temperature is 170°C), bake it at a temperature of 230°C for 5 minutes to form a glove.

The thickness of gloves is generally 20-50um.

The comprehensive beneficial effects of the present invention are: the present invention solves the disease infection brought to the user by the bacteria or microorganisms breeding and multiplying during the use of gloves, the unique small size effect, quantum effect and comparative The large specific surface area has better antibacterial effect and more stable physical and chemical properties compared with traditional silver nanoparticles and Ag ⁺ ; the addition of a small amount of lignin significantly promotes the antibacterial effect of silver wire.
