Description

Technical Field

[0001] This invention belongs to the field of protective glove manufacturing technology, specifically relating to a manufacturing process for a cut-resistant and puncture-resistant protective glove. Background Technology

[0002] Protective gloves, as a core component of personal protective equipment (PPE), are widely used in medical, industrial, laboratory, military, and everyday consumer fields. With the increasing demands for performance in PPE from modern industry, security, and special operations, the demand for cut-resistant and puncture-resistant protective gloves is growing. In high-risk work scenarios such as machining, metal handling, glass manufacturing, criminal investigation, and rescue, operators' hands are frequently threatened by sharp objects, including cuts, punctures, and friction. Traditional protective gloves, due to material or structural limitations, struggle to simultaneously meet the dual requirements of high protection levels and wearing comfort.

[0003] Currently, most mainstream cut-resistant and puncture-resistant gloves on the market employ the following technical solutions: 1) Metal fiber blending technology: This involves blending metal fibers such as stainless steel wire and titanium alloy wire with chemical fibers or cotton yarn, utilizing the high strength of the metal to achieve puncture resistance. However, these gloves are stiff, heavy, and prone to hand fatigue after prolonged wear. Furthermore, the metal fibers are prone to breakage, producing burrs and posing safety hazards. 2) Ultra-high molecular weight polyethylene (UHMWPE) fiber weaving technology: UHMWPE fibers have excellent cut resistance, but their puncture resistance is limited by the fiber's linear density and weaving density, offering insufficient protection against fine needle-like sharp objects. Additionally, the material cost is high. 3) Composite lamination structure: This involves bonding multiple layers of materials (such as aramid fabrics, polyurethane coatings, and metal films) with adhesives. However, the interlayer bonding strength is significantly affected by temperature and humidity, leading to delamination and failure after long-term use. The process is also complex and costly. Furthermore, existing technologies generally suffer from the following drawbacks:

[0004] Limited Protective Performance: Most products focus on only one function—cut resistance or puncture resistance—making it difficult to address complex threats (such as scenarios with both sharp edges and pointed objects). Insufficient Comfort and Flexibility: In pursuit of high protection levels, gloves often sacrifice breathability, tactile sensitivity, and finger dexterity, impacting work efficiency. Poor Durability: Repeated bending or friction easily leads to fiber breakage and coating peeling, causing a rapid decline in protective performance. Therefore, there is an urgent need for a manufacturing process for protective gloves that combines high cut resistance, strong puncture resistance, excellent comfort, and long-term durability. Summary of the Invention

[0005] The purpose of this invention is to provide a manufacturing process for cut-resistant and puncture-resistant protective gloves. By combining process optimization and material innovation, this invention aims to solve the problems of insufficient cut resistance and insufficient puncture resistance of existing protective gloves when they collide with sharp objects, making them prone to puncture.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] A manufacturing process for a cut-resistant and puncture-resistant protective glove includes the following steps:

[0008] Step 1: Pre-treat the fiber knitted glove body;

[0009] Step 2: After the pre-treated glove body is molded, it is heated to 45°C for 30 minutes. Then, the preheated glove mold is vertically immersed in the composite coating material. After the immersion is completed, it is first placed in an oven at 80°C for 5 minutes to cure, and then heated to 150°C for 2 minutes to form a nano-ceramic bridging layer.

[0010] Step 3: Prepare nitrile latex A solution and nitrile latex B solution respectively. Immerse the hand mold processed in Step 2 into nitrile latex B solution for 3-5 seconds, then remove it and let it stand for 30-50 seconds. Then pre-bake it at 60℃ for 1 minute and immerse it again in nitrile latex A solution for 8-10 seconds so that the A solution only covers the palm area. Remove it and then place the hand mold in a microwave device for pre-foaming treatment for 30-45 seconds. The microwave power is 300W.

[0011] Step 4: Vulcanize the pre-foamed hand mold at 65℃ for 10-15 minutes, then increase the temperature to 110℃ for 2-3 minutes, and continue vulcanizing at 130℃. At the same time, use near-infrared light to scan the palm area and adjust the infrared scanning speed. After vulcanizing for 5-8 minutes, allow it to cool naturally and then demold to obtain cut-resistant and puncture-resistant protective gloves.

[0012] Preferably, the pretreatment method in step 1 is as follows: argon / oxygen mixed plasma treatment is performed at 60°C using a low-temperature plasma processor, with an argon / oxygen volume ratio of 4:1 and a power of 0.8 W / cm³. 2 Time: 5 minutes.

[0013] Preferably, in step 2, the speed at which the hand mold is vertically immersed into the composite coating material is 8 cm / min, and the lifting speed is 4 cm / min.

[0014] Preferably, the composite coating material is made from the following raw materials in parts by weight: 40-45 parts of silane-modified epoxy resin, 30-32 parts of methyltriethoxysilane, 8-10 parts of nano-silicon carbide, 1-2 parts of graphene nanosheets, 15-20 parts of ethanol / water mixture, and 1-2 parts of ethylene glycol butyl ether.

[0015] Preferably, the composite coating material is prepared by the following method:

[0016] S1: Bisphenol A type epoxy resin E51 and KH550 are mixed evenly at a mass ratio of 10:1. The mixture is heated to 40°C and reacted for 3 hours. After the reaction is completed, silane-modified epoxy resin is obtained.

[0017] S2: Prepare an ethanol / water mixture by mixing anhydrous ethanol and deionized water in a volume ratio of 7:3. Adjust the pH of the mixture to 4.5 using 0.1M hydrochloric acid. Then add methyltriethoxysilane and stir magnetically for 30 minutes at room temperature to obtain mixture A.

[0018] S3: After mixing nano-silicon carbide and graphene nanosheets, mechanical ball milling was performed for 2 hours at a speed of 300 rpm and a ball-to-material ratio of 5:1 to obtain SiC-graphene mixed powder.

[0019] S4: Add the SiC-graphene mixed powder to the mixture A and ultrasonically disperse for 30 minutes to obtain mixture B;

[0020] S5: After heating the silane-modified epoxy resin obtained in S1 to 40°C, add the mixture B, then add ethylene glycol butyl ether and stir magnetically for 30 minutes. Then let it stand at room temperature in the dark for 90-95 minutes to obtain the composite coating material.

[0021] Preferably, the nitrile latex A solution in step 3 is made from the following raw materials in parts by weight: 500-600 parts nitrile latex, 15-35 parts sulfur, 6-10 parts zinc oxide, 2-3 parts silicon carbide micro powder, 15-25 parts sodium dodecylbenzenesulfonate, 3-5 parts sodium polyacrylate, 6-10 parts antioxidant 264, 8-15 parts accelerator ZDC, and 1-2 parts nano tungsten oxide cesium.

[0022] Preferably, in step 3, the nitrile latex B solution is made from the following raw materials in parts by weight: 300-500 parts nitrile latex, 10-25 parts sulfur, 5-8 parts zinc oxide, 8-12 parts composite foaming agent, 3-5 parts hydroxymethyl ethyl cellulose, 5-8 parts antioxidant RD, and 0.5-1.5 parts silicone defoamer; the composite foaming agent is composed of azodicarbonamide and sodium bicarbonate in a 1:1 mass ratio.

[0023] Preferably, the fiber knitted glove body is made of one or more of ultra-high molecular weight polyethylene fiber and aramid fiber.

[0024] Preferably, in step 4, the near-infrared light scanning wavelength is 808nm, the spot diameter is 20mm, and the spot scanning speed is 5mm / s.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] (1) By combining silane-modified epoxy resin with methyltriethoxysilane, combined with nano-silicon carbide and graphene nanosheets, a high-hardness and high-toughness ceramic-polymer composite coating material is formed. The surface of the glove body fiber is effectively activated by argon-oxygen mixed gas low-temperature plasma treatment, which improves the adhesion of the subsequent coating material. After coating, the coating is pre-cured at 80℃ and sintered at 150℃ in two steps to promote the cross-linking of resin and nanoparticles, forming a stable "bridging" structure and preventing the coating from peeling off. This process can make the composite coating material form a high-hardness and high-toughness ceramic protective layer on the fiber surface, which greatly improves the anti-cutting and anti-puncture performance.

[0027] (2) The gloves of this invention adopt a differentiated functional design in different areas. In the palm area, a composite structure is formed by two impregnations: a B-liquid foamed bottom layer (flexible cushioning) + an A-liquid highly filled surface layer (wear-resistant and puncture-resistant). The back of the hand uses lightweight foamed B-liquid to achieve a balance between high-strength protection in key areas and flexible breathability in non-operational areas. At the same time, a zoned vulcanization treatment is adopted. Near-infrared scanning is used for the palm area, and a specific scanning speed and range are set. Since the palm contains nano-tungsten oxide cesium microwave absorbing material, it can locally heat up to about 160°C to accelerate cross-linking, while the back of the hand, which is not scanned by infrared, is vulcanized at 130°C. This achieves zoned vulcanization of different areas, and precise directional vulcanization of the palm area, ensuring high hardness of the palm and good flexibility of the back of the hand. At the same time, the infrared scanning speed and range are reasonably set to avoid embrittlement of the rubber layer caused by local over-vulcanization.

[0028] (3) Through the collaborative innovation of materials, processes and structures, this invention achieves a balance between protective performance and wearing comfort. The protective gloves produced have a cut resistance of GB24541-2022 standard level E, and a puncture resistance and tear resistance of level 4. They also have good breathability and excellent durability. They are particularly suitable for high-risk operation scenarios such as military, security and metal processing, and have significant technological progress and industrialization value.

[0163] Performance testing

[0164] The gloves prepared in Examples 1-4 and Comparative Examples 1-4 of the present invention were subjected to performance tests. The performance of cut resistance, tear resistance and puncture resistance was tested according to standard GB24541-2022, and the air permeability was tested according to GB / T5453-1997. The specific test results are shown in Table 1.

[0165] Table 1 Performance Test Results

[0166]

[0167] As can be seen from the results in Table 1 above, the gloves prepared in Examples 1-4 of this invention all achieved a cut resistance of approximately 25N, a cut resistance level of 5, and a puncture resistance exceeding 150N, which is far higher than that of Comparative Examples 1-4. This indicates that the composite coating material (containing nano-silicon carbide and graphene) and the partitioned impregnation + infrared vulcanization process of this invention significantly improve the protective performance of the gloves. The significant decrease in cut resistance and puncture resistance of Comparative Example 1 indicates that the nano-ceramic bridging layer plays a key role in improving the protective performance of the substrate. This is because the silane-modified epoxy resin composite nano-silicon carbide / graphene coating forms a high-hardness, high-toughness ceramicized protective layer on the fiber surface, significantly improving the cut resistance and puncture resistance. The back-of-hand breathability of Comparative Example 2 is low, and the tear resistance of Comparative Example 2 is also significantly reduced, indicating that the lack of a foamed buffer layer leads to poor glove flexibility. The cut resistance and puncture resistance of Comparative Example 3 (without infrared partitioned vulcanization) are significantly lower than those of Examples 1-4, indicating that infrared partitioned vulcanization is crucial for strengthening the palm area, increasing the crosslinking density, and enhancing local protection capabilities. Comparative Example 4 (mixed impregnation) showed lower performance across all aspects compared to Examples 1-4, particularly in breathability and protection. This demonstrates the irreplaceable advantages of the zoned impregnation design, as mixed impregnation cannot simultaneously meet the requirements for both protection and comfort. This invention utilizes a nano-ceramic bridging layer as the puncture-resistant matrix and impregnates the palm area with nitrile latex B+A to form a dual-layer structure offering both flexible cushioning and rigid protection. Furthermore, infrared zoned vulcanization achieves localized reinforcement, resolving the long-standing contradiction of "high protection - low comfort" in the field of protective gloves. The resulting protective gloves exhibit excellent performance. Comparative data demonstrate that the absence of any step in this process leads to a significant performance decrease, indicating that each step in the process of this invention is indispensable.

[0168] It should be noted that the above embodiments are merely some preferred embodiments of the present invention, and not all embodiments. Obviously, based on the above embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
