Abstract

The invention can be used to produce chloroprene rubber based rubbers and improves their physical and mechanical properties. The mixture includes chloroprene rubber, 2-mercaptobenzthiazole, 4-thiazolidone-2-thione, stearic acid, paraffin, phenyl-β-naphtylamine, dibutyl phthalate, chalk, kaolin, technical carbon, magnesia and zinc oxide. Before mixing, zinc oxide and / or magnesium oxide are treated with laser radiation at a wavelength of 694.3 nm with a pulse repetition rate of 2 Hz, a duration of 30 ns, a power of 10 MW in the dose range of 150-450 pulses or x-ray irradiation to an absorbed dose of 8-13 krad, and then the remaining ingredients are added to the pre-mix. 3 tab.

(54) METHOD FOR PRODUCING A RUBBER MIXTURE FOR CABLE SHELLS

(57) The invention can be used. The invention relates to the technology of producing protective sheaths for cable products, in particular, to a method for producing a rubber mixture for cable sheaths, and can be used to produce rubber based on chloroprene rubber.

The purpose of the invention is to increase fi-. ziko-mechanical indicators of rubber.

Example. The compositions of the mixtures produced by the proposed and known methods are given in table 1. The mixtures manufactured by the proposed method contain zinc oxide or magnesium oxide, or zinc oxide and magnesium oxide, treated with laser radiation with a wavelength of 694.3 nm

It is used to obtain chloroprene rubber based rubber and improves their physico-mechanical properties. The mixture includes chloroprene rubber, 2-mercaptobenzthiazole, 4-thia-ZOLIDON-2-TION, stearic acid, paraffin, phenyl-p-naphthylamine, dibutyl phthalate, chalk, kaolin, carbon black, magnesium oxide and zinc oxide. Zinc oxide and / or magnesium oxide are mixed with a laser wavelength before mixing. 694.3 them with a pulse repetition rate of 2 Hz, a duration of 30 NS, a power of 10 MW in the dose range of 150-450 pulses or X-ray irradiation up to an absorbed dose of 8-13 krad, and then introduced into a pre-made mixture of other ingredients. 3 tab.

pulse repetition rate of 2 Hz, a duration of 30 no, with a capacity of 10 MW. For zinc oxide, the irradiation dose is 400 pulses and 10 krad, and for magnesium oxide, 300 pulses and -1 O krad.

The treated oxides are introduced into a rubber mixture previously manufactured according to conventional technology, which includes all the ingredients (Table 1), except

oxides. I

The properties of the mixtures obtained by the proposed and known methods are given in table. 2
