    This invention relates to the field of medicine, namely desmurgy. The goal is to increase the strength of the dressing. The fixing belt is made by soaking the plaster bandage with an aqueous polymer dispersion and layering its layers on the affected part of the body, alternating rounds of the bandage based on polyurethane and polyvinyl alcohol moistened with water, and then finishing the fabrication of the band with tours of the plaster bandage, water-saturated dispersant with water dispersion, and soaking with water dispersant. and a copolymer of ethylene and vinyl acetate.

    The invention relates to medicine, namely desmurgii.
    The aim of the invention is to increase the strength of the band edge.
    Use the following components.
    1. Gypsum bandage. Conventional gypsum bandages are used, in which 500-600 g / m2 of gypsum are applied on a cotton carrier.
    2. Plastic resin based bandages. Plastic resin-based bandages are used, where 150 ± 20 May is applied to a textile cotton carrier weighing 60 ± 10 g / m2. % of polyurethane containing aromatic isocyanate groups (NCO content 18 ± 3 wt.%, viscosity 10QOO-25000 mPa s at 25 ° С).
    3. Disperse plastics.
    a) Polyurethane dispersion. The polyurethane dispersion used can be obtained as follows.
    1632 parts of polyether diol based on 1,6-hexanediol, 2,2-dimethylpropane-1,3 and adipic acid, having a hydroxyl number of 63, are dehydrated at 100 ° C under vacuum (about 14 Torr) and after adding 85 h polyester mono alcohol from n-butanol, ethylene oxide and propylene oxide (in a molar ratio of 83:17) having a hydroxyl number of 30, is mixed with a mixture of 244.2 parts of 3-isocyanatomethyl-3,5,5-trimethyl-hexyl isocyanate and 185 h. 1,6-hexane diisocyanate. The mixture is stirred at 100 ° C until it contains 4.6% by weight of NCO. After cooling to 50-60 ° C, 3200 parts of anhydrous acetone are added. To this acetone solution is slowly added a mixture of 107 parts of (2-amino-ethyl) -2-aminoethanesulfonic acid sodium and 10 parts of hydrazine monohydrate dissolved in 260 parts of water. After additional mixing for 10 minutes

    WITH
    with vigorous stirring, 2280 parts of water are slowly added. This forms a bluish-white solid dispersion in a mixture of water and acetone. After removal of the acetone by distillation, the aqueous dispersion of a solid substance with a concentration of 50% remains. The particle diameter is 200-20 nm (determined by light scattering).
    The dispersion solid contains 3.1% polyethylene oxide units and 3 equivalents of sulphonate groups () per 100 g of solid.
    b) Polyvinyl resin based dispersion. Aqueous dispersions of a copolymer of vinyl acetate and ethylene, pH 4, particle size 0.5-1 μm are used.
    PRI me R 1 (obtaining impregnated plaster bandages). In 1900 g of a 5% polyurethane dispersion by weight, 14 gypsum bandages measuring 8 x 400 cm (dry weight about 170 g) are successively dipped for 4-5 seconds until air bubbles are no longer formed. Bandages are only weakly squeezed, removed and then processed into appropriate samples. Examine the remaining dispersion: an amount of 780 g, a solids content of 5.65 wt.%. This means that as a result of the treatment with a polyurethane water dispersion, 14 gypsum bandages absorbed 51 g of a solid contained in the initial dispersion, which corresponds to an impregnation level of 2.3%.
    EXAMPLE 2. Samples of the following quality are manufactured: an internal diameter of 87 mm, a width of 90 mm.
    Sample A:
    Layer: a plaster bandage of 10 x 300 cm in size is immersed for 5 s in a 10% by weight dispersion of a resin based on ethylene and vinyl acetate and wound three times on the appropriate sleeve (diameter of 87 mm).
    Layer: A plastic resin resin bandage with a size of 10 x 300 cm is immersed in water for 5 seconds while squeezing and wound onto the existing plaster layer twice.
    Layer: a plaster bandage of 10 x 300 cm in size is immersed for 5 seconds in a 10% by weight dispersion of a resin based on ethylene and vinyl acetate and wound three times on an existing bandage based on a plastic resin.
    After curing and removal of the liner, a molded article is obtained having a tensile strength of 19 N / cm in the radial direction.
    Sample B:
    The layer is the same as for sample A, however, instead of a dispersion of a resin based on ethylene and eninyl acetate, a 10% polyurethane dispersion is used.
    Layer as in sample A.
    Layer as in sample A, but instead of a dispersion of a resin based on ethylene and vinyl acetate, a 10% by weight dispersion of polyurethane is used. The tensile strength of 19.2 N / cm (defined as in sample A).
    Example Samples of the following quality are made: internal diameter 100 mm, width 90 mm.
    Sample A:
    Layer: 8 x 400 plaster bandage
    cm immersed for 5 s at 5% by
    mass dispersion of polyurethane and three times
    wound on the appropriate sleeve
    (diameter 10cm).
    Layer: A bandage based on a plastic resin measuring 7.5 x 300 cm is immersed in water and squeezed onto a gypsum layer.
    Layer: 8 x 400 plaster bandage
    cm immersed for 5 s at 5% by
    mass dispersion of polyurethane and three times
    wound on the available bandage based on
    plastic resin.
    After curing and removing liner
    get a molded product having in
    radial direction certain
    the method of ultimate strength
    13.6 N / cm.
    Sample B:
    Layer as in sample A.
    Layer as in sample A, but instead of water also use 5% by weight dispersion of polyurethane.
    Layer as in sample A.
    Strength of 14,6 N / cm.
    The samples described in the examples given, in particular, have rapid curing, reliable release of excess water, high adhesive strength between the individual layers, high elasticity, high water resistance, high resistance to fracture, especially at the edges.
