FIELD: chemistry.SUBSTANCE: invention relates to a method and a composition for manufacturing a multi-layered elastomeric film, suitable for gloves. The composition for manufacturing the elastomeric film contains a synthetic elastic polymer or a copolymer. The total concentration of solid substances in the composition constitutes 5-20 wt % of the composition weight. The method of manufacturing the elastomeric film with the application of a multi-layered coating contains the following stages: (i) dipping the mould into a coagulant with the content of calcium ions and concentration of 1-10 wt %; (ii) drying the dipped mould; (iii) dipping the mould into the composition for the elastomeric film manufacturing with the temperature of 25-45°C with a 1-10 s exposure; (iv) drying the elastomeric film composition; (v) re- dipping the mould into the composition for the application of the next layer of the elastomeric composition; (vi) optional repetition of stages (iv) and (v); (vii) drying and vulcanisation of the multi-layered elastomeric film with the average layer thickness from 6 to 90% of the average total thickness of the multi-layered film, and the average total thickness of the multilayered elastomeric film from 0.01 to 0.3 mm.EFFECT: invention makes it possible to increase the strength of the finished film without defects, does not cause skin allergy.12 cl, 10 tbl, 2 ex |
