Problems solved by technology

[0005] At present, the common processing methods of waterproof and oil-proof paper are translucent paper, vegetable parchment paper, metal box, plastic film laminated paper, processed paper coated or impregnated with polyvinyl alcohol and other chemicals. The mechanism is to form a physical barrier on the surface of the base paper to slow down or make it almost impermeable to the oil through the paper, but at the same time, it also greatly reduces the original air permeability of the paper, and it is difficult to make waste paper recycling or natural degradation, causing environmental hazards

Embodiment 1

[0037] Take 2% of nano-titanium dioxide, 4% of fluorocarbon coupling agent, 5% of fluorine paper oil repellent and water-based stearic acid, 5% of sodium tripolyphosphate and 84% of tap water; the particle size of nano-titanium dioxide is 30nm.

[0038] The nano-titanium dioxide and fluorocarbon coupling agent are ultrasonically oscillated in an ultrasonic cleaning machine. The power of the ultrasonic wave is controlled to 2000W, the frequency is 500HZ, and the oscillation time is 5min. Coating; then, under the condition of mechanical stirring at a stirring speed of 500r / min, sequentially add sodium tripolyphosphate, fluorine paper oil repellent, aqueous stearic acid and water to the above-mentioned homogeneous aqueous solution, and stir for 3 hours to obtain A waterproof, oil-proof and antibacterial coating with a solid content of 40%; then, the prepared waterproof, oil-proof and antibacterial coating is coated on paper, and the coated paper is placed in an oven at a temperatu...

Embodiment 2

[0040] Take 5% of nano titanium dioxide, 8% of TX-10, 8% of fluorocarbon waterproof and oil repellent agent and water-based zinc stearate (mixed in a mass ratio of 1:1), 5% of sodium pyrophosphate, and 74% of tap water; the particle size of nano titanium dioxide is 30nm.

[0041] Ultrasonic oscillation of nano-titanium dioxide and TX-10 in an ultrasonic cleaning machine, control the ultrasonic power to 2000W, frequency of 800HZ, oscillation time of 8min, disperse evenly, form a uniform aqueous solution, and make TX-10 coat nano-titanium dioxide; Then, under the condition of mechanical stirring with a stirring speed of 800r / min, sodium pyrophosphate, fluorocarbon water and oil repellent, water-based zinc stearate and water were sequentially added to the above-mentioned homogeneous aqueous solution, and stirred for 3 hours to obtain a solid content of 45 % waterproof, oil-proof and antibacterial coating; then, the prepared waterproof, oil-proof and antibacterial coating is coate...

Embodiment 3

[0043] Take nano-titanium dioxide 8%, OP-10 and fluorocarbon coupling agent (mass ratio 1:1 mixed) 9%, fluorocarbon waterproof and oil-repellent agent and water-based calcium stearate 10%, urea 10%, tap water 63%; The particle size of titanium dioxide is 40nm.

[0044]Nano-titanium dioxide, OP-10 and fluorocarbon coupling agent are ultrasonically oscillated in an ultrasonic cleaning machine. The power of the ultrasonic wave is controlled to 2000W, the frequency is 1800HZ, and the oscillation time is 18min. The fluorocarbon coupling agent is used to coat nano-titanium dioxide; then, under the condition of mechanical stirring at a stirring speed of 800r / min, urea, fluorocarbon water and oil repellent, water-based calcium stearate and water are sequentially added to the above-mentioned homogeneous aqueous solution. , stirred for 3.5h to obtain a waterproof, oil-proof and antibacterial coating with a solid content of 55%; then, the prepared waterproof, oil-proof and antibacterial ...

Abstract

The invention discloses water and oil proofed and antibacterial paper. The water and oil proofed and antibacterial paper comprises a water and oil proofed and antibacterial coating and is prepared from the following components in percentage by weight: 2 to 8% of antibacterial agent, 3 to 9% of migration agent, 2 to 10% of water and oil proofing agent, 1 to 10% of dispersing agent, and 63 to 92% of water, wherein the antibacterial agent is nanometer titania. The paper has both the water and oil proofing function and antibacterial function. The invention also provides a preparation method of the water and oil proofed and antibacterial paper. The preparation method comprises the following steps of: firstly, wrapping the antibacterial agent with the migration agent; secondly, sequentially adding the dispersing agent, water and oil proofing agent and water to a homogeneous aqueous solution generated by the antibacterial agent and the migration agent so as to obtain the water and oil proofed and antibacterial coating; and thirdly, coating the prepared water and oil proofed and antibacterial coating onto the paper, and drying. By adopting the preparation method, the physical performance and printing performance of the paper are remained, the paper can be prevented from water and oil permeation, has a lasting antibacterial performance, and is resistant to high temperature and high in safety for a human body.

Description

technical field [0001] The invention relates to antibacterial paper, in particular to a waterproof and oil-proof antibacterial paper and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, health awareness continues to increase, especially the outbreak and prevalence of various diseases in recent years, making people pay more and more attention to the impact of various infectious diseases and diseases caused by harmful bacteria on human health. serious harm caused. Paper products are widely used in people's lives. Household paper, kitchen paper, food packaging coated paper, decorative paper, sanitary and medical paper, banknote paper, etc. play an important role in people's production and life. Therefore, , the development of paper with antibacterial function is an inevitable requirement to protect human health. [0003] The antibacterial effect of antibacterial paper is bec...
