| titleOfInvention | Procedure for manufacture of thermo-shrinking material |
| abstract | FIELD: machine building. n SUBSTANCE: invention refers to manufacture of thermo-shrinking materials on base of stabilised and radiation-cross-linked polyethylene designed for packing food products, various items, and thermo-shrinking tubes for protection of cable connections. It can be used at manufacture of items (straps, bands) for protection of pipelines from corrosion. According to the disclosed procedure for manufacture of thermo-shrinking materials a stabiliser chosen from poly-hydro-kinone-di-sulphide, poly-resorcin-di-sulphide or poly-pyro-catechine-di-sulphide is introduced into polyethylene. For uniform distribution of the stabiliser in volume of material the latter is introduced into polyethylene in form of super-concentrate corresponding to granulated source polyethylene containing specified stabiliser with concentration of 5-8%. Produced material is radiated with γ-radiation Co 60 or accelerated electrons with absorbed dose 0.05-0.1 MGr. Radiated material is subjected to thermo-drawing at temperature above temperature of non-radiated polyethylene melting in a lengthwise direction at 10-30%, and in a crosswise direction at 5-8%. Tubes are blown out in diametrical direction for not less, than at 50%. n EFFECT: thermo-shrinking materials with reduced concentration of applied stabiliser, increased strength and elasticity. n 4 cl, 1 tbl, 23 ex |
