Anti-oxidation ageing-resistant adhesive for coaxial cables and production method thereof

Abstract

The invention discloses a non-molten anti-oxidation ageing-resistant functional master batch for producing coaxial cables and a production method thereof. The anti-oxidation ageing-resistant functional master batch for the coaxial cables comprises the following components in percentage by weight: 80.6 percent of polyolefin, 2.4 percent of adhesive and 17 percent of anti-oxidation ageing-resistant agent. The production method of the anti-oxidation ageing-resistant functional master batch for the coaxial cables comprises the following steps of: (1) proportioning the selected polyolefin material and the adhesive in a ratio, and mixing and stirring the polyolefin material and the adhesive for 5 minutes at a high speed; (2) proportioning the selected main antioxidant and the selected auxiliary antioxidant in a ratio of 2:1; (3) mixing 80.6 percent of polyolefin, 2.4 percent of adhesive and 17 percent of anti-oxidation ageing-resistant agent in percentage by weight, and mixing and stirring the materials for 5 minutes at a high speed; and (4) cooling, filling and performing moisture-proof storage. The functional master batch can be produced without a melting method, so energy is saved, loss is reduced and original properties of the materials are ensured.

Description

Technical field: [0001] The invention relates to the technical field of cables, in particular to a coaxial cable anti-oxidation and anti-aging functional masterbatch and a production method thereof. Background technique: [0002] If anti-oxidation and anti-aging materials are not added to the foamed insulating material, the foamed insulating material is prone to aging during use. Signal transmission quality. For this reason, anti-oxidation and aging-resistant materials should be added to the insulating foam materials of coaxial cables used outdoors. However, since most of the anti-oxidation and aging-resistant materials are powdery, if they are directly added, it will cause unevenness, such as melt extrusion. Granulation will cause loss again. For this reason, the present invention uses a stirring method to add an adhesive and an anti-oxidation and anti-aging material to the polyolefin material to directly stir the masterbatch. Invention content: [0003] The object of ...
