Description

The invention relates to personal protective equipment and can be used to protect the skin of human hands from chemical and thermal effects when performing emergency rescue and repair work at enterprises of the chemical industry.

Known anti-acid rubber glove KShchS, type 1 (TU 38.306-5-59-95), as well as a protective glove butyl rubber BL 1-M (TU 006251-80). The gloves listed above, made on the basis of an insulating material, provide protection against chemicals, but do not have fire retardant properties, and are also uncomfortable during operation due to low air permeability, which prevents the perspiration released by the hand.

Known protective glove (patent 2077239, RU, publ. Bull. Inventory No. 1997.04.04), used to protect hands from vibration. The glove includes the back and palm of the hand and located on the palm of the hand pad of vibration-absorbing material.

The vibration damping pad covers the entire palm of the hand and consists of several layers. The upper layer is made of corrugated rubber in the form of conical protrusions, the middle layer is made of foam rubber, and the layer located between them, the lower layer of the palm of the hand and the back are made of rubberized cotton fabric. The glove effectively protects hands from vibration, but does not have protection against thermal effects and chemical hazardous substances.

A protective glove (patent 2041676, RU, publ. Bull. Invent. 1995.08.20), designed to protect the doctor's hands from ultrasound, contains the back and palm parts. To ensure the protective properties of the gloves, the back and palm of the glove are three-layer. The inner layer is made of cotton fabric, the middle layer is made of air-based material based on natural, synthetic (for example, synthetic winterizer) or a mixture of natural and synthetic fibers. A polymer film is used as the outer layer. However, the described product (glove) does not have flame retardant and chemical protective properties.

Known protective glove (patent 2270592, RU, publ. Bull. Invent. 2006.02.27) relating to protective work and sportswear. The glove contains a palm-palm shell with convex contact areas having a configuration that corresponds to the phalanx and palmar fields. On the glove there are also ribbed protrusions on the outer surface, made in the form of differently oriented groups of strips. In this case, the palm-palm casing is made of knitted whole, and the ribbed protrusions are made of polymer elastic material. The invention provides reliable protection for the hands when performing work associated with the danger of damage to the hands on the sharp edges of parts and workpieces, but does not provide protection against thermal and chemical influences.

Known protective glove with high mechanical properties in combination with high chemical and / or radiation resistance (patent 2279234, RU, publ. Bull. Invent. 2006.07.10). The glove contains one or more layers of elastomers that are identical or different. Layers of elastomers are obtained from solutions of elastomers in one or more organic solvents or in water. The layers are reinforced with a layer of fabric. However, the coating technology is complex and specific.

The closest in technical solution is a protective glove with fire retardant properties (patent 2126643, RU, publ. Bull. Invent. 1999.02.27).

The protective knitted glove consists of 2 layers: the outer glove and the inner one. The outer layer is a knitted glove made of fire-retardant and heat-resistant tohilen yarn in combination with high-strength high-modulus CBM thread. The outer glove has the back and palm parts, the back side of the outer glove and the palm part of it are connected by interweaving half-fangs, the upper part of the palm is reinforced with an additional layer of knitwear by interlacing erasers.

The inner glove is made in an all-knit way from cotton yarn by weaving the smooth surface. The use of cotton material gives additional hygienic properties due to the absorption of moisture released by the hand.

The well-known protective glove is laborious to manufacture, uses expensive materials: tohilen yarn and CBM thread and has only flame retardant properties, without providing protection from chemical hazardous substances.

The high cost of the above materials does not meet the requirements of efficiency, allowing widespread use of products made from them.

The technical result of the proposed solution is to give the protective glove both chemical and fire retardant properties.

The technical result is achieved by a design feature and the device of the protective layers of the inventive gloves. The protective glove consists of an outer glove and an inner glove. Each of the gloves has a back and palm parts, and the back side and cuff of the outer glove are made of fireproof textile material; the palm and interdigital inserts of the outer glove are made of an insulating material. The back side and the cuff of the inner glove are made of a chemical protective hot-melt composite material; the palm and interdigital inserts of the inner glove are made of cotton material.

A general view of the protective glove is shown in the drawing.

The protective glove consists of two layers: the outer glove and the inner one. Each of the gloves has a back and palm parts (sides).

The back side (1) and cuff (2) of the outer glove are made of fire-retardant textile material, for example, material with a polymer discrete coating (TU 8318-028-10725218-2004) can be used. Fire-retardant material is a fabric base with a one-sided discrete polymer coating in the form of different geometries, arranged in different combinations with each other, with a flame retardant composition containing emulsion polyvinyl chloride (PVC). Due to the use of material, the product acquires high resistance to high temperatures and open flame. Fire-retardant material has a high degree of wear resistance, thereby contributing to an increase in the life of the product. The product in which this material is used has reliable fire protection.

The palm and interdigital inserts (3) of the outer glove are made of an insulating polymer-textile material using, for example, rubberized fabric based on butyl rubber or its mixture with polymers (Koshelev V.V., Kornev A.E., Bukanov A.M. The general technology of rubber. - M .: Chemistry, 1978. 528 p.). This ensures protection not only from vapors and liquid phases of potent and toxic, but also resistance to aggressive substances (strong oxidizing agents, mineral acids, alkalis, etc.). Polymer-textile material is a textile base (for example, polyamide), on which a thin layer of polymer or a mixture of it with other polymers, for example, butyl rubber and ethylene-propylene triple synthetic rubber, is applied on one or both sides (E. Kozyreva Development of protective materials, resistant to aggressive environments, based on a polymer composition. // International scientific-practical conference of students and young scientists "New technologies and materials in the manufacture of leather and fur." - Kazan, May 2005 - P.40- 43). The textile base serves as a frame and ensures the strength of the fabric as a whole, and a thin layer of polymer is an obstacle to harmful and hazardous chemicals. The use of an insulating material in a protective glove ensures safe operation when in contact with a surface in contact with vapors and aerosols of chemical liquids.

The back side and the cuff of the inner glove (4) are made of a chemical protective hot-melt adhesive material (TU OP 5459-018-00281097-2001), which is a multilayer filtering material based on activated carbon (patent 2281800, RU, publ. Bull. .twenty).

Chemical protective hot-melt adhesive composite material consists of a middle sorption layer, which is used as a carbon-filled creped paper, reinforced on both sides with cushioning material with hot-melt coating (TU 8729-004-05790484-95) or cushioning material on a non-woven base (TU 8729-096-05790484 -97). The sorption layer contains unbleached sulfate cellulose, activated carbon in a certain ratio, and polyvinyl alcohol-water-soluble fibers, the introduction of which significantly improves the strength properties of the material, ensuring a longer preservation of the protective adsorption properties, which leads to an increase in the life of the finished product.

The use of a chemical protective hot-melt adhesive material in the manufacture of a protective glove provides reliable protection of the skin from vapors and aerosols of aggressive and toxic chemicals during emergency rescue operations.

The palm and interdigital inserts (5) of the inner glove in contact with the palm are made of cotton material (for example, calico, chintz). The use of cotton material gives the protective glove additional hygienic properties, absorbing sweat, which is released by the hand.

The glove is made in a cut way and includes the removal of anthropometric data, cutting the material into parts of the palm and back parts and assembling the parts into the product. The back side of the outer and inner gloves fits as one piece with the gaiters, and the palm side of the outer and inner gloves, the gait of the palm side, fingertip and interdigital inserts are separate.

In order to ensure greater fire and chemical protection in the area where the palm and gait parts are joined, the palm of the inner glove (made of cotton) is shorter (1-2 cm) than the palm of the outer glove (made of insulating material) in order to the chemical protective material of the inner glove was superimposed (forming an “overlap”) on the insulating material of the outer glove.

All structural elements (palmar, back, gaiters, interdigital inserts) are fastened together by a thread (such as lavsan), which has strength and incombustibility.

The outer glove at the level of the wrist is equipped with a strap and ties, fastened with a textile fastener 6 (such as "Velcro") to adjust the width of the gloves.

Both gloves are inserted one into the other and fastened (stitched) along the upper edge with the help of a nylon tape or other braid.

Thanks to this design and the combination of layers of various textile materials (chemical and fire retardant, protective material of an insulating type), the protective glove acquires high resistance to the action of hazardous chemicals along with giving it flame retardant properties and ensures a comfortable stay in the product through the use of cotton material. The product has sufficient flexibility, allowing the hand of a person (user) to maintain all mobility when handling objects. The manufacturing technology of protective gloves due to the use of materials based on cheap and affordable raw materials is economical, which allows widespread use of the product made in this way.
