Description

The invention relates to the field of economic and industrial activity in terms of cleaning the contaminated surfaces of dishes, containers and other devices, protecting the surface of the hands and hands from the negative effects of water, detergents, etc.

Known glove containing the palm-palmar membrane with convex contact areas having a configuration corresponding to the phalanx and palmar fields, and ribbed protrusions on the outer surface (RU 2270592 C1, A41D 19/015, 2006, A41D 13/08, 2006 )

A disadvantage of the known glove is that it is designed to protect the hands and hands during precise manual mechanical assembly, associated with the risk of damage to the hands on the sharp edges of parts and workpieces, but does not provide protection for hands and hands when working with detergents, water, etc. ., since the glove is made of knitted fabric. Also, the application of polymer ribbed protrusions on the surface of a knitted glove is a difficult task. In the case of the manufacture of these protrusions from rubber, the technology for their preparation involves the use of special equipment and massive strong forms with their filling with a crude rubber mixture and the subsequent vulcanization operation carried out at high pressures (above 10 atm) and temperatures (above 100 ° C), which is essential complicates the manufacturing process of the glove both in terms of labor intensity and in terms of material and energy costs.

In the case of using the technology of applying liquid compositions for the manufacture of polymer ribbed protrusions, it is necessary to use solvents, which are mostly harmful to humans and the environment.

Known protective glove containing an external base and protective elements embedded in the external base. Protective elements are embedded in the area of the fingers and are made in the form of durable and flexible thimbles. The invention relates to means for protecting hands from cuts and punctures in an industrial environment, in particular in nuclear production (RU 2425611 A41D 19/015, 2006).

The disadvantage of this prototype is the use of embedded protective elements that carry the protective function of the operator’s hands in the nuclear industry and are not necessary and inconvenient when working on cleaning contaminated surfaces. In addition, in the case of embedded elements made of metal, the gloves are heavy and wear out quickly.

Known mittens with a protective coating of a polymeric material made of an inner fabric base with an outer layer of a polymeric material. The invention relates to protective work clothing, to personal protective equipment for human hands for use in aggressive environments, at low temperatures, with oilfield equipment (RU 2104663 C1, A41D 13/10, A62B 17/00).

The disadvantage of this prototype is that the mitten is not convenient for enhanced separation of contaminants from the surfaces to be cleaned, due to the coating of the entire surface of the glove with a sufficiently thick polymer layer. In addition, as a protective polymer coating, a multicomponent composition based on polyether urethane is used, and the technology for its manufacture and application is complex, time-consuming and costly. The use of solvent in the manufacture and application of the polymer composition is chemically and fire hazardous and involves the use of all equipment and the production room in an explosion-proof design (Acetone boiling point 56 ° C). The use of an insulating inner layer for gloves designed to clean contaminated surfaces is impractical, and the performance in the form of a mitten makes it impossible to thoroughly clean the contaminated surface.

Known vibration-protective gloves (semi-gloves), including the back and palms, napalka and a pad of vibration-absorbing elastic damping material, characterized in that the vibration-absorbing elastic-damping layer of the lining is made in the form of seven damping elements located between the cover layer and the lining, and the back of the glove (semi-glove) tightened with elastic braid at the level of the leggings grind line (RU 107669 U1, A41D 19/015, 2006).

The disadvantage of this prototype is its specificity, namely the use for working with a vibratory tool, as well as the absence of a special surface for enhanced separation of contaminants from the surfaces to be cleaned.

Known composition for applying a protective coating on the gloves. The composition relates to the production of personal protective equipment against aggressive influences, in particular the protective coating of mittens for work in the oil field (RU 2206253 C1, A41D 19/015, A41D 13/00, C08L 27/06).

The disadvantage of this prototype is the complexity of the composition, the difficulty of the technological process of its manufacture and application, the absence of a special surface for enhanced separation of contaminants from the surfaces to be cleaned. In the prototype, only gloves are claimed to be made, while gloves are more effective for cleaning contaminated surfaces.

The difficulty in cleaning contaminated surfaces lies in the fact that during the cleaning process the operator must have protective gloves and a device for eliminating pollution, such as a washcloth, sponge, brush, etc. The idea is to combine the operator’s hand protection functions and the cleaning device into a single unit.

Closest to the claimed invention relates to patent RU (11) 2452459 (13) C1, which describes a medical glove with printing. Unlike the prototype, according to the claimed invention, instead of font characters, washing elements from a composition based on polyurethane foam are applied to the glove.

Claims (2)

1. A glove containing a shell in the shape and size of the hand, having at least finger and palm fields, characterized in that the glove is made of rubber, latex, spunbond and any other waterproof elastic material, coated from the inner surface with a washing layer of elastic or semi-rigid polyurethane foam with a thickness of 0.5 to 1.5 cm, applied by free pouring at a temperature of 10 ° to 60 ° C in prefabricated molds made of wood or compositions based on wood, metal, porcelain and other glass shaped materials, polymer composite material: thermoplastics, thermoplastic elastomers, rubbers, rubbers, monolithic polymers, including filled or reinforced so that the washing surface is located on the glove on the inner surface of the fingers, excluding the thumb, and palm, or separately on the finger part gloves and in the palm of your hand, while the index finger is completely covered with a washing surface on all sides. 2. The glove according to claim 1, characterized in that the washing surface consists of a layer of abrasive material with a size of 10-20% of the thickness of the layer of the foamed composition and elastic polyurethane foam, or polyurethane foam filled with agricultural grain waste is used as a washing surface: buckwheat husks, rice, sunflower, etc. in an amount of from 5 to 70% by weight of an elastic to semi-rigid polyurethane composition at ambient temperature, which, when foaming the composition, is firmly bound to the foam material, spread Lying on the outer surface of the foam for more successful removal of contaminants.
