Description

Manufacturing method of sword-proof gloves containing steel yarn and sword-proof gloves manufactured thereby

The present invention relates to a method for manufacturing a knife-proof glove containing steel yarn and a knife-proof glove manufactured thereby, and more particularly, to an industrial site or crime scene where knives, sharp tools, or sharp materials and products are handled, and the wearing comfort is reduced. The present invention relates to a method for manufacturing a sword-proof glove containing a steel yarn capable of preventing and protecting a wearer's palm or fingers from injury and a sword-proof glove manufactured thereby.

In general, industrial sites use various types of safety gloves to protect workers' hands and prevent products or tools from slipping. Since cut-resistant safety gloves with enhanced properties are used, wearing of such cut-resistant safety gloves is designated and obliged by law in Europe and other countries.

Specifically, cut-resistant safety gloves are mainly used in workplaces that use cutting tools such as knives or saws, such as meat processing and marine product processing, or workplaces that handle sharp metal materials and metal products, such as automobile factories, steel mills, and shipyards. However, it is usually knitted using aramid or high molecular weight/ultra high molecular weight polyethylene (HMWPE, UHMWPE) fibers.

However, safety gloves using aramid and high molecular weight/ultra high molecular weight polyethylene fibers have excellent cutting strength compared to ordinary gloves, but most of them do not secure sufficient cutting strength with a cutting strength of 4 or less, and are not only suitable for European standards. It did not reach the 'F' grade.

Accordingly, safety gloves using thick aramid of high denier or high molecular weight/ultra high molecular weight polyethylene fibers have been manufactured to secure sufficient cut resistance to prevent cuts, but in this case, the safety gloves are thick and stiff, significantly reducing workability. A problem has occurred.

In addition, in the case of Dyneema yarn among ultra high molecular weight polyethylene (UHMWPE) fibers, it is expensive and there are economic constraints to use at the work site.

On the other hand, there are cases where wire or glass yarn is used instead of expensive dyneema yarn, but it is not flexible and it is not easy to bend and stretch compared to improved cutting resistance. Not only could it not be used as a glove for sophisticated work such as handling, but if a short circuit occurs in the wire or glass yarn, the end of the wire or glass yarn protrudes to the surface of the glove, impairing the feeling of wearing and injuring the hand of the glove wearer. There were also problems.

Since the configuration is a well-known technology, a detailed description thereof will be omitted for convenience of description and clarity of the technical idea of the present invention.

On the other hand, in another embodiment according to the present invention, in order to prevent the first yarn and the second yarn from being contaminated and to improve flame retardancy, antibacterial properties and strength, the first yarn and the second yarn are immersed in an immersion liquid for 10 to 20 minutes. After soaking for a while, drying at a temperature of 50 to 60 ° C., coating the dried first yarn and second yarn with a binder to prepare a coated first yarn and a second yarn, and the coated first yarn and the second yarn. It is also possible to manufacture anti-knock gloves by weaving two yarns.

An immersion liquid prepared by the following method may be used as the immersion liquid.

First, a first solution may be prepared by mixing purified water with sodium citrate, sodium phosphate, succinic acid, and titania sol and then stirring.

In the above step, the first solution was mixed in a weight ratio of 8 to 12 parts by weight of sodium citrate, 3 to 7 parts by weight of sodium phosphate, 13 to 17 parts by weight of succinic acid, and 8 to 12 parts by weight of titania sol with respect to 100 parts by weight of purified water. It can be prepared by stirring after.

In the above step, the sodium citrate and sodium phosphate are included to improve the deodorizing effect and increase stability, the succinic acid is included to increase the odor removal efficiency of the sulfur compound-based material, and the titania sol increases the activity of visible light indoors, such as fluorescent lamps. And it may be included to exert excellent air purification performance in the visible light region of the room.

For example, the titania sol is prepared by adding 350 g of distilled water to a half container, maintaining a temperature of 55° C., and adding triton X-100 (triton-X(C ₁₄ H ₂₂ O (C ₂ H ₄ O)). After adding 0.25 g of n)) and stirring at 480 rpm for 45 minutes, 120 g of titanium tetraisopropoxide (Ti(OC ₃ H ₇ ) ₄ ) was added in three portions at 40 g intervals of 3 minutes, and 75 g at 480 rpm. After stirring for 15 minutes, 15 g of formic acid (HCOOH) and 12 g of 34.5% hydrogen peroxide were added in that order, stirred for 4 hours, and then 0.57 g of sulfur (S) was added, followed by reflux stirring at 125 ° C. for 5 hours. can

Since the configuration of the triton X-100 in the above step is a well-known technique, a detailed description thereof will be omitted for convenience of description and clarity of the technical idea of the present invention.

Next, a second solution may be prepared by adding starch, silver nano-zeolite, boric acid, and poly melamine sulfonate to the first solution and then stirring.

In the above step, the second solution contains 5 to 10 parts by weight of starch, 0.1 to 0.3 parts by weight of silver nano-zeolite, 0.1 to 1 part by weight of boric acid, and 0.5 parts by weight of poly melamine sulfonate, based on 100 parts by weight of the first solution. It may be prepared by stirring after mixing in a weight ratio of from 1.5 parts by weight to 1.5 parts by weight.

In the above step, the starch is a mixture of amylose and amylopectin, which is a polysaccharide made by linking long numbers of D-glucose (glucose) through a condensation reaction. The molecular weight is 50,000 to 200,000, and the specific gravity is 1.65. When hot water is poured into the starch or water is poured and heated, the starch particles expand to become a highly viscous liquid.

The silver nano-zeolite is obtained by adsorbing nano-silver to the pores of the zeolite, and as the nano-silver is adsorbed to the pores of the zeolite, the surface area of the silver increases, so that the antibacterial effect of the silver can be increased. In addition, far-infrared rays can also be emitted by the zeolite used as a carrier.

In the present invention, the silver nano-zeolite is prepared by impregnating zeolite powder in silver nano-water mixed with silver nano-zeolite. Preferably, the silver nano-zeolite may have an average particle size of 19,000 to 21,000 mesh.

The boric acid is a white crystal, soluble in water, and the solution is acidic and has a bactericidal action. can be included to prevent this.

The poly melamine sulfonate functions as a fluidizing agent, and the poly melamine sulfonate, the fluidizing agent, strongly disperses the particles of the composition to form a horizontal surface, thereby ensuring smooth workability.

Subsequently, an immersion liquid may be prepared by mixing cypress tree extract, peroxyacetic acid, TPO (Thermo Plastic Polyolefine; thermoplastic polyolefin elastomer) resin, and purified water with the second solution and then stirring.

In the above step, the immersion liquid is 0.5 to 1.5 parts by weight of cypress tree extract, 0.1 to 1 part by weight of peroxyacetic acid, and 10 to 20 parts by weight of TPO (Thermo Plastic Polyolefine; thermoplastic polyolefin elastomer) resin based on 100 parts by weight of the second solution. And it may be prepared by stirring after mixing in a weight ratio of 1 to 10 parts by weight of purified water.

The cypress tree extract can be extracted from the cypress tree by a known method. The cypress tree contains a component called phytoncide, and is composed of phenolic compounds including terpenes, alkaloid components, and glycoside components. As a 100% natural substance that is difficult to combine, it is a natural antibacterial agent with various effects such as strong antibacterial and antifungal action without resistance, stress relief, skin sedation, sleep inducing effect, allergic skin disease improvement and immune function enhancement.

The peroxyacetic acid has a molecular formula of CH ₃ COOOH, and is known to have high reactivity and the ability to eradicate various types of bacteria with just a few drops by an oxygen radical. The hydrocarbon end of peroxyacetic acid easily penetrates into microbial cells such as bacteria and decomposes SS and SH bonds inside and outside of microorganisms to induce rapid and effective antibacterial activity.

When peroxyacetic acid comes into contact with an organic substance, atomic oxygen radicals are generated as shown in [Scheme 1] below, and the generated oxygen radicals oxidize the contacted organic substances to exert a sterilizing effect.

[Scheme 1]

CH ₃ COOOH + H ₂ O ↔ CH ₃ COOH + O ₂

Therefore, in general, peroxyacetic acid is widely used as a cleaner for medical devices to remove pathogenic microorganisms, and is used in various fields such as air conditioner filters, cookware cleaners, and hand cleaners.

The TPO (Thermo Plastic Polyolefine; thermoplastic polyolefin elastomer) resin has excellent tensile strength and processability. It has excellent waterproofness and wind resistance, and above all, it is an eco-friendly thermoplastic material and has high mechanical strength.

For example, the TPO (Thermoplastic Polyolefine) resin is from the group consisting of PE (Polyethylene) resin, PP (Polypropylene) resin, polybutylene resin, ethylene-propylene copolymer resin, and ethylene-vinyl alcohol copolymer resin Any one or more selected resins may be used.

The binder can increase the antibacterial and antiodor activity of the anti-sword glove and improve the physical properties of the glove itself. The binder includes polybutylene adipate terephthalate resin, polysiloxane, alkoxysilane, graphene, thermally conductive polymer, photocatalyst, flame retardant adjuvants and 1,3,5-triglycidyl isocyanurate.

The polybutylene adipate terephthalate (PBAT) is a biodegradable bioplastic and is an environmentally friendly material that is 100% decomposed in the ground within 6 months. It can be obtained by condensation polymerization of 4-butanediol, adipic acid and terephthalic acid.

As such a PBAT resin, one directly synthesized by such a general method may be used, or a commercially available resin such as ECOPLEX (BASF) or PBG7070 (Samsung Fine Chemical) may be obtained and used. there is.

In addition, the PBAT resin may have a weight average molecular weight of 150,000 to 400,000. As the PBAT resin has this molecular weight range, the compatibility and processability of the PBAT resin with other materials such as polysiloxane are more excellent It can be, and can exhibit more improved physical properties according to the relatively high molecular weight.

The polysiloxane may provide excellent water repellency and water repellency durability to the surface of the cool pad fabric by providing excellent water repellency.

The polysiloxane may be represented by the following [Formula 1].

[Formula 1]

In [Formula 1], R ⁴ is each independently a hydrogen atom, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted C6 to C30 aromatic organic group, an acrylate organic group, an epoxy organic group, or any of these combination, X is a hydrogen atom, a hydrogen sulfide group, a substituted or unsubstituted C1 to C10 alkyl group, an acrylate organic group, an epoxy organic group, or a combination thereof, and n is a weight average molecular weight (Mw) of polysiloxane of 1,000 g /mol to 100,000 g/mol is an integer greater than or equal to 1.

For example, the polysiloxane may include dimethylpolysiloxane and organopolysiloxane, and the dimethylpolysiloxane and organopolysiloxane may be used in combination such that the ratio is 3:7 to 7:3.

The alkoxysilane can function as a crosslinking agent, surface treatment agent, adhesion promoter, and internal reinforcing agent, and generally strengthens the bond between an inorganic surface and an organic binder and can help exhibit various improved physical properties such as chemical resistance and moisture resistance. It is being used so that

The alkoxysilane is RnSi(OR')4-n (where R is an alkyl group having 1 to 4 carbon atoms, R' is an alkyl group having 1 to 3 carbon atoms or an acyl group having 1 to 3 carbon atoms, and n is 1, 2 or 3) can be represented.

The graphene is the most excellent material among existing materials in various characteristics such as strength, thermal conductivity, electron mobility, deodorization and antibacterial properties. Accordingly, it is applied to various fields such as displays, secondary batteries, solar cells, automobiles, and lighting, and is recognized as a strategic core material that will lead the growth of related industries, and the technology for commercializing graphene is receiving a lot of attention.

That is, graphene is a carbon allotrope of a two-dimensional structure in which carbon atoms form a hexagonal honeycomb lattice structure by sp ² hybridization, and the thickness of single-layer graphene is 0.2 to 0.3 nm, which is the thickness of one carbon atom. Since graphene has high electrical conductivity and specific surface area, it is used in supercapacitors, sensors, batteries, electrodes (electrode active material) for actuators, touch panels, flexible displays, high-efficiency solar cells, heat dissipation films, coating materials, seawater desalination filters, and secondary batteries. It is used in various fields such as electrodes and ultra-fast chargers.

The flame retardant satisfies Restriction of Hazardous Substances (RoHS), and brominated flame retardants may be used as the flame retardant. In general, halogen flame retardants compete with oxygen for radicals generated in a combustion process, and halogenated radicals are chained. It does not propagate the reaction, so the fire goes out.

Specifically, active radicals OH and active radicals H, which play a role in driving combustion, are trapped and stabilized by HX, and HX is non-flammable and has a dilution effect and an oxygen blocking effect, so flame retardancy is exhibited.

Among halogens, iodine is the most effective flame retardant element, but is expensive and lacks heat resistance and light resistance.

In contrast, bromine is the second most effective flame retardant element after iodine and is most widely used because it can produce a high flame retardant effect in a small amount that does not affect the physical properties of the polymer. In particular, the phenomenon that only traces of carbonization are visible after digestion is a distinctive feature from existing flame retardants.

For example, in the present invention, the brominated flame retardant includes tetrabromobisphenol-A (tetrabromobisphenol-A TBBA, TBBPA), tetrabromobisphenol-A ether, 1,2-bis (tribro 1,2-bis(tribromophenoxy)ethane, 2,4,6-tribromophenyl glycidyl ether, tetrabromophthalic anhydride (tetrabromophthalic anhydride), dimethyl 4-bromophthalate, tetrabromo phthalic disodium, decabromodiphenyl ether, decabromodiphenyl oxide , DBDPO), decabromodiphenyl ethane (DBDPE), 1,4-bis (pentabromophenoxy) tetrabromobenzene (1,4-bis (pentabromophenoxy) tetrabromobenzene), tribromophenoxyethane (tribromophenoxy ethane), 1,2-bis(pentabromophenyl)ethane, bromo trimethylphenyl indane, pentabromobenzyl acrylate At least one selected from the group consisting of pentabromodiphenyl benzyl bromide and hexabromobenzene may be used, and preferably the brominated flame retardant is decabromodiphenyl ethane, DBDPE) may be used.

The flame retardant adjuvant consists of flame retardant compounds such as antimony trioxide and antimony pentoxide, metal antimony and antimony trichloride such as sodium antimonate, aluminum hydroxide, magnesium hydroxide, zinc borate, zinc stannate, molybdate, zirconium, and mixtures thereof. It may be selected from the group, preferably, antimony trioxide may be used as the flame retardant adjuvant.

The antimony compound itself has extremely limited flame retardancy, but when combined with a halogenated flame retardant, it exhibits a synergism effect that greatly increases the radical trapping effect.

Typically, the antimony trioxide reacts with halogen to generate SbOCl and SbCl ₃ , SbCl generates HCl to exhibit a radical trapping effect, SbCl ₃ is also a heavy gas and exhibits an oxygen shielding effect, and SbOCl exhibits a dehydrocarbonization action. do.

The 1,3,5-triglycidyl isocyanurate may be used as a curing agent, and the 1,3,5-triglycidyl isocyanurate is included in a binder to proceed with a curing reaction to improve mechanical and chemical properties. can be secured

For example, the 1,3,5-triglycidyl isocyanurate preferably has a glass transition temperature (Tg) of -20°C or less and a number average molecular weight (Mn) in the range of 1000 to 1500. do.
