A fully sealed coating layer 6 is provided under the shaped layer 5, and the surface layer 1 of the pad is coated with nano-silver-loaded titanium dioxide. The super absorbent layer 4 is equipped with a water absorption factor. The super absorbent layer 4 is made of super absorbent resin and porous The polymer can absorb menstruation and can also lock the loss of menstruation, which can keep the surface of the sanitary napkin dry. The breathable bottom film 6 can reduce moisture and prevent the user from feeling stuffy. The user feels refreshed and comfortable. The first laminate 7 is installed on the left and right sides of the release layer 5. The release layer 5 and the friction pad 14 are fixedly connected, and the structure of the friction pad 14 is a concave-convex structure. The friction pad 14 It is fixed on the lower surface of the release layer 5 so that the friction pad 14 and the underwear can be in contact with each other, so that the friction pad 14 on the uneven surface can rub against the underwear, so as to avoid the problem of sanitary napkin sliding. The left and right ends of the surface layer 1 are equipped with second laminations 8, and the upper surface of the second lamination 8 is provided with a round hair layer 9 and a bristle layer 10, and the bristle layer 10 is installed on the left side of the round hair layer 9. The pad surface layer 1 and the second laminate 8 are fixedly connected, while the round hair layer 9 and the bristle layer 10 are adhesively connected. The pad surface layer 1 is coated with nano-silver-loaded titanium dioxide, which is Combining the antibacterial effect of metallic Ag with nano-TiO 2 Combined with its photocatalytic antibacterial properties, it can not only kill bacteria, but also penetrate cell membranes, destroy cell membrane structures, and degrade the later pollution caused by endotoxins; and, its antibacterial properties are different from general antibacterial materials with the consumption of fungicides However, it reduces or even disappears, which will produce long-lasting antibacterial properties. The surface layer 1 of the pad coated with nano-silver-loaded titanium dioxide can facilitate the fixation of the sanitary napkin through the connection with the second laminate 8. The round hair layer 9 and the bristles The adhesion of the layer 10 can facilitate the fastening of the sanitary napkin to the underwear and prevent the problem of unstable fixation of the sanitary napkin. The upper surface of the pad surface 1 coated with nano-silver-loaded titanium dioxide is provided with a laminate 11, and the laminate 11 The inner side is provided with a through hole 12, and the through hole 12 penetrates the inner side of the laminate 11, so that the blood flowing to the edge of the sanitary napkin can be blocked, and the through hole 12 can absorb the blood at the edge of the sanitary napkin. A first leakage hole 13 is installed in the middle part of the protective pad surface 1 coated with nano-silver-loaded titanium dioxide, and the outer side of the first leakage hole 13 is connected with a chute 16, and the outer side of the chute 16 is connected with a second leakage hole 15. The structure of the leak hole 13 and the second leak hole 15 are both funnel-shaped structures, and the first leak hole 13 forms a communication structure between the chute 16 and the second leak hole 15. The through hole 12 on the upper surface of the cushion surface 1 It is set in a funnel-shaped structure, so that the infiltrated liquid is not easy to return. The first leak 13 and the second leak 15 are connected through the chute 16, so that the blood can be diffused and the blood can be avoided. Will not accumulate in the same place, greatly improving the practicability of this kind of bactericidal cushion.
[0033] The manufacturing method of nano silver-carrying titanium dioxide includes the following steps:
[0034] Obtain urea solution;
[0035] After mixing and stirring the urea solution, dispersant and chloride salt solution for 1 hour at room temperature, the first solution is obtained;
[0036] The mass fraction of the urea solution is 30%;
[0037] The dispersant is polyvinylpyrrolidone;
[0038] The chloride salt solution is a sodium chloride solution with a mass fraction of 30%;
[0039] Drop the silver-containing solution into the first solution to obtain a second solution;
[0040] The silver-containing solution is a silver nitrate solution with a mass fraction of 20%;
[0041] At room temperature, the silver nitrate solution was added dropwise to the first solution at a rate of 1 mL/min, and after stirring for 0.5 h, the second solution was obtained;
[0042] Obtain a solution containing titanium;
[0043] Drop the titanium-containing solution into the second solution to obtain a third solution;
[0044] The titanium-containing solution is tetrabutyl titanate;

[0046] At room temperature, the titanium-containing solution was added dropwise to the second solution at a rate of 0.5 mL/min. After stirring for 0.5 h, the third solution was obtained; the third solution was stirred and reacted at 80 °C for 2 h, and then 0.1 mL /min Then the solution is filtered, centrifuged, and the precipitate obtained is washed with deionized water 3 times, and then the precipitate is dried in a vacuum drying oven at 60°C for 10 hours, and finally placed in a muffle furnace for roasting, the specific roasting procedure It is: heat up to 300°C at a heating rate of 5°C/min and roast for 2h; then heat up to 500°C at a heating rate of 3°C/min and roast for 4h; then heat up to 650°C at a heating rate of 1°C/min , Calcined for 2h to obtain nano silver-loaded titanium dioxide.
[0047] Working principle: For this kind of protective pad with bactericidal effect, the first lamination 7 and the second lamination 8 can be fixed on both ends of the release layer 5 and the surface layer 1 of the protective pad. The bristle layer 10 and the round hair layer 9 provided on the surface of the laminated sheet 7 and the second laminated sheet 8 can sometimes bond the bristle layer 10 and the round hair layer 9 to form a Velcro. The napkin is tied to the underwear, so as to avoid the damage to the underwear caused by the adhesion of viscose, and the friction pad 14 can be attached to the surface of the underwear, which can increase or decrease the friction, so that the sanitary napkin can be fixed. Covered with nano-silver-carrying titanium dioxide, nano-silver-carrying titanium dioxide has good photochemical properties and high stability. Under the excitation of near ultraviolet light, electrons transition from the valence band to the conduction band to form holes and electron pairs, which activate the water Oxygen produces hydroxyl free radicals, and hydroxyl free radicals have a very high oxidizing ability and can effectively degrade organic matter and environmental pollutants. When bacteria are adsorbed on the surface of titanium dioxide, the active oxygen O 2- And free radicals OH can penetrate the cell wall of bacteria, enter the bacteria body, prevent the transmission of membrane-forming substances, block its respiratory system and electronic transmission system, thereby effectively killing bacteria, the first ultra-soft dust-free paper bag set The covering layer 3 can improve the comfort of the sanitary napkin when it comes in contact with the female genitals. The super absorbent layer 3 has super absorbent and water-locking capacity, so that the surface of the sanitary napkin can be kept dry. The super absorbent layer 3 can pass the coagulant Play the role of blood coagulation, the breathable bottom film layer 4 can play a role in reducing moisture, the release paper layer 5 provided can play a role in fixing and protecting the friction pad 14, and the laminate 11 can prevent blood flowing to the edge of the sanitary napkin. Play a blocking role. The through hole 12 can absorb blood at the edge of the sanitary napkin. The first leak hole 13 and the second leak hole 15 on the surface of the pad surface 1 coated with nano-silver-loaded titanium dioxide can absorb blood and make blood flow. Circulation, the connected chute 16 can spread the blood in a large area and avoid the accumulation of blood, so that the practicability of the entire sterilization pad is well improved, and the entire sterilization pad is completed in this way. Use process.
