Embodiment 1

[0015] Embodiment 1: a kind of preparation method of nanometer multifunctional auxiliary agent, is made up of the following steps:

[0016] (1) Prepare 15kg of nanoscale titanium dioxide, 5kg of nanoscale zinc oxide, 15kg of nanoscale magnesium hydroxide and 15kg of nanoscale aluminum hydroxide respectively; the particle size of the titanium dioxide particles is 2 nanometers.

[0017] (2) Weigh the above materials and mix them into the reaction kettle, add 50kg of deionized water and stir at a speed of 600 rpm, after stirring for 10 minutes, raise the temperature in the kettle to 60°C, and add 0.3kg of surface-modified Auxiliary phosphate, after fully stirring and reacting for half an hour, add dropwise 0.3kg of titanic acid coupling agent and 0.3kg of emulsifier OP-10, emulsifier OP-10 is a condensation product of alkylphenol and ethylene oxide; then Raise the temperature to 75°C, stir and react at constant temperature for 2 hours, then cool naturally to 40°C to proceed to th...

Embodiment 2

[0022] Embodiment 2: a kind of preparation method of nanometer multifunctional auxiliary agent, is made up of the following steps:

[0023] (1) Prepare 14kg of nanoscale titanium dioxide, 5.5kg of nanoscale zinc oxide, 14kg of nanoscale magnesium hydroxide and 16kg of nanoscale aluminum hydroxide respectively; the particle size of the titanium dioxide particles is 5 nanometers.

[0024] (2) Weigh the above materials and mix them into the reaction kettle, add deionized water and stir to prepare a slurry with a concentration of 45%. The stirring speed is 650 rpm. After stirring for 12 minutes, the temperature in the kettle is raised to 55°C , add 0.4kg of surface modification additive TX-10, stir and react for 40 minutes, add dropwise 0.4kg of titanic acid coupling agent and 0.4kg of emulsifier OP-6, then raise the temperature to 80°C, stir and react at constant temperature for 100 Minutes later, it was naturally cooled to 30°C to proceed to the next step.

[0025] (3) Put the ...

Abstract

The invention relates to a preparation method of a nano multifunctional assistant and an application thereof. The method comprises the steps of (1) preparing nano-scale titanium dioxide, zinc oxide, magnesium hydroxide and aluminum hydroxide respectively; (2) mixing materials according to a certain proportion, adding deionized water, stirring to prepare slurry with the concentration of 40 percent-60 percent, and carrying out the modification to obtain modified slurry; (3) adding deionized water to dilute to the concentration of 10 percent-20 percent, pouring 2-6kg of nano silver-silicon compound and a dispersant in a kettle and stirring to react; (4) slowly dripping 6-12kg of fluorine-containing resin in the kettle under specific conditions, adding a coupling agent and the dispersant to react, keeping the temperature for 50-250 minutes and finally cooling and discharging. The product produced by the method has a plurality of functions of flame-retardant, anti-bacteria, anti-fungus, anti-water, anti-oil, anti-fouling and the like. The prepared nano multifunctional assistant can be applied in a variety of textiles.

Description

technical field [0001] The invention relates to a preparation method and application of a nanometer multifunctional additive. Background technique [0002] At present, the nanocrystalline compounds appearing on the market are basically single-function bactericidal additives, and are widely used in compounding with resins, coatings and other materials to make products such as nano-antibacterial resin composite materials or nano-composite antibacterial coatings. However, with the improvement of people's living standards, materials with single functions, such as bactericidal materials, mildew-proof materials, waterproof, oil-proof, and anti-fouling materials, can no longer meet the needs of the market. In the process of building and decorating homes or service places, consumers often need to spend a lot of manpower and material resources to select and purchase a variety of products with different functions, and then to achieve sterilization, disinfection, mildew resistance, wat...
