Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

DETAILED DESCRIPTION

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0020] Embodiment 1: Reference Figure 1 , which is the first embodiment of the present invention, provides a high-performance polypropylene plastic woven bag, including the following specific components: polypropylene, talcum powder, anti-ultraviolet agent, antistatic agent, and toughening agent.

[0021] The mass fractions of the above ingredients are as follows: Polypropylene is 90 parts; Polypropylene is the main material of plastic woven bags, which has excellent corrosion resistance, rigidity and high tensile strength.

[0022] talcum powder is 8 parts; Talc is often used to enhance the fluidity of plastics and reduce friction during the production process, thereby improving production efficiency.

[0023] UV inhibitor is 2 parts; Used to improve the UV resistance of plastic woven bags and extend their service life.

[0024] Antistatic agent is 2 parts; It is used to prevent dust or other debris from sticking to plastic bags due to static electricity during use, ensuring that the bags are clean and dust-proof.

[0025] Toughener is 3 parts; Toughening agents are used to improve the impact resistance of polypropylene, so that the woven bags can still maintain good toughness in low and high temperature environments.

[0026] Among the specific components: The anti-ultraviolet agent is one of diphenylbenzotriazole, titanium dioxide, and hydroxyphenyltriazine compounds. Diphenylbenzotriazole can effectively absorb ultraviolet rays and convert them into heat, thereby reducing the degradation of polypropylene by ultraviolet rays. Titanium dioxide, as a common ultraviolet absorber and catalyst, can effectively delay the aging process of polypropylene under sunlight exposure. Hydroxyphenyltriazine compounds have good ultraviolet absorption and protection effects, and can improve the anti-aging properties of plastics.

[0027] The antistatic agent is one of quaternary ammonium salt compounds, olefin-based polymers, and silicone antistatic agents. Quaternary ammonium salt compounds form a charge shielding layer with the surface of polypropylene through their positively charged structure, which can effectively reduce the accumulation of static electricity. Olefin-based polymers (such as polyurethane) have strong antistatic properties and can form a thin film on the surface of plastics to inhibit the generation of static electricity. Silicone antistatic agents adhere to the surface of plastics through chemical reactions, reduce friction, avoid static electricity accumulation, and will not affect other properties of plastics.

[0028] The toughening agent is one of polyurethane resin, styrene-butadiene copolymer, and polyether toughening agent. Polyurethane resin forms a cross-linked network with polypropylene through its unique molecular structure, which significantly improves the impact strength and flexibility of plastics. Styrene-butadiene copolymer, as a typical elastomer, can improve the toughness and low-temperature performance of polypropylene. Polyether toughening agent: It has good low-temperature toughness, is suitable for use in low-temperature environments, and can effectively prevent plastic brittle cracking.

[0029] The high-performance polypropylene plastic woven bag also includes additives, which include superconducting nano-graphene oxide, micron-scale composite materials, photocatalysts, composite microcapsules, and silicon nitride microparticles; The mass fractions of the additives are as follows: Superconducting nanographene oxide is 1 part; As a nanomaterial, graphene has excellent electrical conductivity and mechanical strength. Adding a small amount of superconducting nanographene oxide can further improve the tensile strength and electrical conductivity of polypropylene woven bags, and help improve their antistatic properties. This material can effectively enhance the strength and anti-aging properties of the bag while keeping the bag light.

[0030] 1 part for micron-scale composite materials; The components of the micron-scale composite material include an inorganic part, an organic part and a coupling agent, the inorganic part adopts bentonite, the organic part adopts a silanization modifier, and the coupling agent adopts an epoxy resin coupling agent; Bentonite, in micron-sized particles, is used to enhance the tensile strength and corrosion resistance of polypropylene; The silanization modifier uses γ-aminopropyltriethoxysilane to chemically modify the surface of bentonite through organic silane molecules, so that its surface can better chemically combine with polypropylene, which is used to enhance the dispersibility and interface adhesion of the composite material; Epoxy resin coupling agent is used to promote the cross-linking between bentonite and polypropylene and improve the bonding of the organic-inorganic interface.

[0031] In this embodiment, the components of the micron-scale composite material include, by weight: Bentonite: 70-80 parts; Silanization modifier: 15-20 parts; Coupling agent: 5-10 parts.

[0032] By combining inorganic bentonite with organosilicon compounds, the wear resistance and corrosion resistance of polypropylene can be effectively enhanced, especially for oils, chemical solvents, etc. This additive not only enhances the durability of the bag, but also helps improve its performance in harsh environments.

[0033] Photocatalyst is 0.5 parts; Titanium dioxide, as a common photocatalyst, can decompose harmful substances under sunlight, reduce the accumulation of toxic substances in plastic bags, and has a self-cleaning function. Its addition can effectively reduce environmental pollution and improve the environmental performance of polypropylene bags.

[0034] The composite microcapsule is 0.5 parts; The components of the composite microcapsule include antibacterial substances, capsule wall materials and stabilizers, and the components are in the following mass parts: Antibacterial substances: 60-70 parts; Capsule wall material: 20-30 parts; Stabilizer: 5-10 parts.

[0035] Furthermore, in the composite microcapsule: Antibacterial substances include nanosilver, ammonium chloride, and zinc oxide; nanosilver has strong antibacterial and antiviral effects and can effectively inhibit the growth of bacteria and mold. Ammonium chloride has a broad-spectrum antibacterial effect, especially in inhibiting bacterial growth. Zinc oxide not only has antibacterial effects, but also has certain antioxidant properties, which can further improve the durability of the material.

[0036] The capsule wall material is made of polyurethane, chitosan or gelatin, which can effectively encapsulate the antibacterial substance and control its release.

[0037] Stabilizers include glycerin and polyvinyl alcohol to prevent leakage or destruction of antibacterial substances during production and use.

[0038] Encapsulating antibacterial substances in microcapsules can enable polypropylene plastic woven bags to continuously release antibacterial ingredients during long-term use. This innovative additive can significantly improve the antibacterial properties of the bag and prevent the bag from being contaminated by bacteria when storing food, medicine and other items.

[0039] The amount of silicon nitride microparticles is 0.3 parts.

[0040] Silicon nitride has extremely high wear resistance and thermal stability. Adding it to polypropylene can not only enhance the mechanical strength of the bag, but also improve its stability in high temperature environments, which is especially advantageous when storing and transporting high-temperature items.

[0041] In this embodiment, the additives include: Superconducting nano-graphene oxide reacts with polypropylene to enhance the mechanical properties and electrical conductivity of woven bags. The reaction formula is as follows: ; In the formula, For superconducting nanographene oxide, The superconducting nano graphene oxide is a polypropylene monomer; by hot pressing, a stable chemical connection is formed between the superconducting nano graphene oxide and the polypropylene monomer; The photocatalyst reacts with polypropylene to improve its UV resistance. The reaction formula is as follows: ; In the formula, Titanium dioxide photocatalyst, It is a polypropylene monomer; under ultraviolet light, titanium dioxide and propylene monomer undergo a photocatalytic reaction to enhance UV resistance.

[0042] Embodiment 2: Reference Figure 2 , which is the second embodiment of the present invention, and provides a method for producing a high-performance polypropylene plastic woven bag, based on the high-performance polypropylene plastic woven bag described in the first embodiment, comprising the following specific steps: S1, premixing talcum powder and polypropylene, and adding an anti-ultraviolet agent, an antistatic agent and a toughening agent to obtain a mixture A; First, the polypropylene is dried to ensure that its moisture content is less than 0.2% to avoid hydrolysis during the subsequent production process. Other additives such as talcum powder, anti-ultraviolet agents, antistatic agents and toughening agents should also be evenly dispersed in advance and kept dry.

[0043] Talc is pre-mixed with polypropylene using efficient mixing equipment. Anti-UV agents, anti-static agents and toughening agents are added together at this stage to ensure that they are evenly distributed in the polypropylene matrix. This pre-treatment ensures that the mechanical strength, anti-UV ability and anti-static effect of polypropylene in subsequent steps are effectively enhanced.

[0044] S2, mixing the superconducting nano-graphene oxide, silicon nitride microparticles and micron-sized composite material with the mixture A using a high shear mixing device to obtain a mixture B; Superconducting nano-graphene oxide and micron-scale composite materials are added to polypropylene. First, superconducting nano-graphene oxide is dispersed evenly in the polypropylene matrix through ultrasonic dispersion technology. Then, the micron-scale composite material is fused with polypropylene through mechanical mixing. The addition of silicon nitride microparticles will enhance the surface hardness of polypropylene and improve its wear resistance and high temperature resistance. Using efficient dispersion technology, nano-graphene oxide and composite materials can be evenly distributed in polypropylene, improving its mechanical strength, wear resistance and chemical corrosion resistance.

[0045] The nanomaterials and composites were thoroughly mixed with the polypropylene using high shear mixing equipment to ensure that there was no agglomeration on the surface.

[0046] S3, melt-extrude the mixture B to form a uniform polypropylene melt; When the mixture B is melt extruded, the mixture B is fed into a single screw or twin screw extruder for melting, and the melting process allows the polypropylene to be fully mixed within a temperature range of 180-220° C. Through this process, the mechanical properties of the polypropylene are further improved, and the effects of other functional additives are also optimized.

[0047] S4, adding a photocatalyst into the polypropylene melt; Titanium dioxide is added to the polypropylene melt as a photocatalyst. Under the irradiation of ultraviolet light, titanium dioxide can decompose organic pollutants attached to the surface, making the material self-cleaning. At the same time, the addition of titanium dioxide can enhance the ultraviolet resistance of polypropylene and extend the service life of the material. This step requires ensuring that titanium dioxide is evenly distributed in the polypropylene.

[0048] Use an efficient mixer to mix quickly in a short time to avoid precipitation of titanium dioxide. At this time, a coupling agent can be added appropriately to enhance the bonding strength between titanium dioxide and polypropylene.

[0049] S5, adding the composite microcapsules into the polypropylene melt; The composite microcapsules containing antibacterial substances are evenly dispersed in the polypropylene melt. The embedding effect of the microcapsules can ensure the slow release of antibacterial substances, thereby improving the antibacterial properties of the woven bags in long-term use. At this stage, the addition of microcapsules not only enhances the hygienic properties of polypropylene, but also enhances the durability of the material through the slow release effect.

[0050] Ensure uniform distribution of microcapsules in the polypropylene matrix and prevent microcapsules from breaking during processing.

[0051] S6, shaping the polypropylene plastic woven bag through a cooling device and solidifying it into a final plastic woven bag; After extrusion, the polypropylene melt is cooled by a cooling device and solidified into the final woven bag structure. During this process, the cooling speed must be controlled to avoid thermal stress and thermal deformation. At the same time, the cooled polypropylene woven bag will be stretched and formed to ensure that it has excellent tensile strength and good dimensional stability.

[0052] Control the cooling rate to ensure that the woven bag is cooled evenly and achieves the required physical properties.

[0053] S7. Carry out quality inspection on plastic woven bags and package the finished products.

[0054] In this embodiment, the quality inspection includes a tensile strength test, an anti-ultraviolet performance test, an antistatic test, and an antibacterial test.

[0055] The test contents are shown in Table 1.

[0056] The test results show: Tensile strength: The test results show that the tensile strength of the material is 45 MPa, which means that the polypropylene woven bag exhibits strong tensile resistance when subjected to external force, can maintain high strength under normal conditions, and is suitable for packaging applications with heavy loads.

[0057] Anti-ultraviolet performance: The results of the UV accelerated aging test show that the UV weathering index of the material is as high as 98%. Even after 500 hours of UV exposure, the physical properties of the polypropylene woven bag do not change much. This shows that the material has strong UV resistance, is suitable for long-term outdoor exposure, and is not easy to age or become brittle.

[0058] Antistatic performance: The antistatic test results show that the static voltage on the surface of the material is 1.2 kV, showing good antistatic performance. This means that the woven bag can effectively prevent static electricity accumulation, help avoid damage caused by static electricity during packaging, and is especially suitable for electronic component packaging.

[0059] Antibacterial property: Antibacterial test shows that the inhibition rate of the material against Escherichia coli and Staphylococcus aureus is as high as 99%, indicating that the polypropylene woven bag has a strong antibacterial effect and can effectively reduce the reproduction of bacteria. It is suitable for use in food, medicine or other industries with high hygiene requirements.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
