Embodiment 1

[0031] Such as figure 1 , figure 2 As shown, the antibacterial and deodorant paper diapers of the present invention include a blended base film 1 of PBAT and PLA and an absorber located in the middle of the base film 1, the absorber and the base film 1 are bonded by structural glue 5, and the base film 1 It is in the shape of "I", and the absorber includes a large cotton core 2, a small cotton core 3 and a natural plant fiber spunlace non-woven fabric 4 bonded with structural glue 5 in sequence. The large cotton core 2 is dumbbell-shaped, and the surface is provided with a diamond honeycomb The embossing structure is formed by dissolving the blend pulp of primary reed and bamboo, and polymer water-absorbing agent; the small cotton core 3 is elliptical, and the surface is provided with linear embossing. Treated sodium polyacrylate mixed with acid polymer water-absorbing agent. The dosage ratio of sodium polyacrylate and primary bamboo dissolving pulp in the small cotton core...

Embodiment 2-3

[0034] The structure of the antibacterial and deodorant paper diapers is the same as that of Example 1, except that 1g and 0.5g of ZEM enzymes are rotated and sprayed in the small cotton core.

[0035] Because the absorbent body is made of a mixture of original dissolving pulp and polymer, it has super liquid absorption; the small cotton core of the absorbent body is added with sodium polyacrylate after bridging treatment, which has a certain odor suppression function and can also improve liquid absorption. The absorption rate; the added ZEM enzyme can quickly absorb and decompose the odorous substances in the body fluid, and at the same time protect the skin; the non-woven fabric layer is made of spunlace non-woven fabric, which further improves the antibacterial ability; Wired embossing is conducive to the radial diffusion of liquid and improves the diffusion efficiency; the surface of the large cotton core is provided with diamond honeycomb embossing, which increases the con...

experiment example 1

[0037] Prepare a urine reagent for use. The content of each component in the reagent is 35.0 g of urea, 16.5 g of sodium chloride, 3.0 ml of phosphoric acid, 2.0 ml of sulfuric acid, 1.2 g of calcium phosphate, and 0.65 ml of ammonia water.

[0038] In a glass box with an operating port, draw 100ml of the prepared urine reagent with a disposable straw and inject it into 10 antibacterial diapers of Example 2 and the commercially available antibacterial and deodorant diapers with built-in bamboo charcoal strips for 1 minute, 5 Minutes, 10 minutes, 30 minutes, and 1 hour to observe the absorption, odor, surface color, and corrosion.

[0039] test results:

[0040] For the 10 diapers of Example 2, all the urine reagent in the straw was squeezed out within 5 seconds, and there was no residual floating liquid on the surface of the diapers. After 1 minute, the surface of the diaper is refreshing and semi-dry; after 5 minutes, the surface humidity of the diaper is further reduced.

Abstract

The invention discloses a fully-degradable environment-friendly paper diaper, which comprises a bottom film and an absorption body positioned at the middle position of the bottom film, wherein the absorption body is bonded with the bottom film by adopting a structural adhesive; the absorption body comprises a large cotton core, a small cotton core and a non-woven fabric which are bonded in sequence by using the structural adhesive; the large cotton core is formed by mixing crude dissolved pulp and a high-polymer water absorbent; the small cotton core is formed by mixing crude dissolved pulp and an acid high-polymer water absorbent; the bottom film is a blended film of PBAT (Poly Butylene Terephthalate) and PLA (Poly Lactic Acid). By adopting the fully-degradable environment-friendly paper diaper, various environmental pollution problems are solved, and the treatment cost is reduced greatly; moreover, with the superior anti-bacterial and deodorization functions, the type of disposable article becomes more popular, and the health of users is protected.

Description

technical field [0001] The invention relates to the technical field of degradable paper diapers. Background technique [0002] With the continuous development of the economy and the continuous innovation of product quality, the consumption of children's diapers in my country is increasing day by day. In addition, with the advent of an aging population, the number of incontinent patients such as long-term bedridden patients and severe patients is also increasing, and incontinence products are also attracting attention. There is no need to count the amount of usual feminine hygiene products. In short, the number of similar hygiene products is huge every year. [0003] However, with the increase of such hygienic products that absorb bodily fluids, the pressure on the environment is also increasing, because these sanitary products are non-degradable disposable daily products. The current treatment method is to incinerate or landfill together with domestic waste, which not onl...
