[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a photodegradable woven bag. (See also...) Figures 1-5 A photodegradable woven bag includes a woven bag body 1, which includes a woven layer 2, an anti-corrosion layer 21, and a photodegradable layer mechanism 3. The anti-corrosion layer 21 is disposed on the inner side of the woven layer 2, and the photodegradable layer mechanism 3 is disposed on the outer side of the woven layer 2. A first adhesive layer 22 is disposed between the anti-corrosion layer 21 and the woven layer 2. A sealing plate 4 is disposed on one side of the top opening end of the woven bag body 1. The woven layer 2 is made of a biodegradable synthetic polyester material, which is easily photo-oxidized and degraded under light and oxygen conditions. The anti-corrosion layer 21 is made of a material with a biodegradable synthetic polyester material as the matrix mixed with an organosilicon quaternary ammonium salt antibacterial agent, which has good toughness and anti-corrosion properties. The photodegradable layer mechanism 3 uses a photocatalyst to improve the photosensitivity of the woven layer 2, thereby accelerating the photo-oxidation degradation reaction of the woven layer 2 under light and oxygen conditions. The sealing plate 4 facilitates the opening and closing of the woven bag body 1.

[0025] The photodegradation layer 3 includes a second adhesive layer 31 and a photocatalytic layer 32. The second adhesive layer 31 is bonded to the outside of the braided layer 2, and the photocatalytic layer 32 is bonded to the outside of the second adhesive layer 31. Micro-grooves 34 are formed on the outer surface of the braided layer 2, and venting holes 35 are formed on the surface of the braided layer 2. The second adhesive layer 31 is made of epoxy chain extender, which has good adhesion and compatibility. The epoxy chain extender is used to improve the adhesion and compatibility between the braided layer 2 and the photocatalytic layer 32. The photocatalytic layer 32 is a photocatalyst synthesized by adding polylactic acid as the matrix and photoinitiator iron stearate and titanium dioxide. The micro-grooves 34 formed on the outer surface of the braided layer 2 increase the specific surface area of ​​the braided layer 2 and improve the light acquisition rate of the braided layer 2. The venting holes 35 formed on the surface of the braided layer 2 increase the oxygen contact area, thereby achieving the purpose of improving the photo-oxidative degradation rate of the braided layer 2.

[0026] Reference Figure 1 , Figure 2 and Figure 3 A first sealing strip 36 is provided on the inner side of the sealing plate 4, and a second sealing strip 43 is provided on the outer side of the photocatalytic layer 32. The first sealing strip 36 and the second sealing strip 43 are engaged and locked together. A slot 37 is provided on the outer side of the first sealing strip 36, and a locking strip 44 is provided on the outer side of the second sealing strip 43. The slot 37 and the locking strip 44 are engaged and locked together. An adhesive block 41 is fixedly connected to the outer side of the sealing plate 4. A handle 42 is provided on one side of the adhesive block 41. After the sealing plate 4 is folded, the first sealing strip 36 and the second sealing strip 43 are attached together, and the locking strip 44 is locked in the slot 37. Thus, the sealing plate 4 is stably folded and locked on one side of the woven bag body 1. The woven bag body 1 can be easily lifted by the handle 42 and the adhesive block 41.

[0027] Reference Figure 4 and Figure 5 The photocatalytic layer 32 has light-transmitting holes 33 on its surface, which penetrate the second adhesive layer 31 and the photocatalytic layer 32. The inner side of the first adhesive layer 22 is bonded to the outer side of the anti-corrosion layer 21, and the outer side of the first adhesive layer 22 is bonded to the inner side of the braided layer 2. The surface of the first adhesive layer 22 has dissolution holes 23, which connect the braided layer 2 and the anti-corrosion layer 21. By opening light-transmitting holes 33 on the surface of the photocatalytic layer 32, which penetrate the second adhesive layer 31 and the photocatalytic layer 32, the light and catalyst transmittance is increased, thereby improving the light acquisition rate of the braided layer 2 and accelerating the photo-oxidative degradation of the braided layer 2. The anti-corrosion layer 21 has improved adhesion and compatibility with the braided layer 2 through the first adhesive layer 22. The dissolution holes 23 on the surface of the first adhesive layer 22 increase the rate at which the photocatalyst penetrates from the braided layer 2 to the anti-corrosion layer 21, thereby improving the efficiency of the photo-oxidative degradation of the anti-corrosion layer 21.

[0028] Working principle: In use, the sealing plate 4 is used to fold and seal the woven bag body 1. The first sealing strip 36 and the second sealing strip 43 are attached, and the locking strip 44 is locked in the locking groove 37. At this time, the sealing plate 4 closes the opening of the woven bag body 1. The woven bag can be easily lifted and used using the handle 42 on the adhesive block 41. The anti-corrosion layer 21 set on the inner side of the woven layer 2 improves the anti-corrosion effect of the woven layer 2. The first adhesive layer 22 improves the adhesion and compatibility between the woven layer 2 and the anti-corrosion layer 21. The photodegradation layer mechanism 3 set on the outer side of the woven layer 2 accelerates the photo-oxidation degradation process of the woven layer 2 when the woven bag is discarded. The second adhesive layer 31 improves the adhesion and compatibility between the woven layer 2 and the light. The adhesion and compatibility of the catalyst layer 32, the photocatalyst of the photocatalyst layer 32 accelerates the photodegradation rate of the braided layer 2 under light and oxygen conditions, the light-transmitting holes 33 on the photocatalyst layer 32 improve the transmittance of light and photocatalyst, thereby improving the photodegradation efficiency of the braided layer 2, the micro-carved grooves 34 of the braided layer 2 increase the specific surface area under light, the venting holes 35 on the braided layer 2 increase the oxygen contact area, thereby further improving the photodegradation oxidation reaction process of the braided layer 2, and the dissolution holes 23 of the second adhesive layer 31 accelerate the rate at which the photocatalyst permeates through the second adhesive layer 31 and combines with the anti-corrosion layer 21, thereby improving the photodegradation oxidation reaction rate of the anti-corrosion layer 21.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
