Abstract

The invention belongs to the field of self-repaired material preparation and provides a cable material with self-repaired functional composite gel and a preparation method. The preparation method comprises the following steps: mixing a solid initiator with nano clay granules, performing cold welding so as to obtain composite granules, putting into a reaction container with a dissolved polymer monomer, performing polymerization and cross-linking winding under the action of the initiator so as to obtain composite gel with a self-repairing function, and performing blending extrusion with a substrate resin and aids, thereby obtaining the cable material with the self-repaired functional composite gel. Compared with a conventional method, the preparation method has the functions that the reaction velocity of the initiator and the cross-linking degree of the gel are effectively increased, the gel is high in mechanical property, high in self-repairing efficiency and high in property, reactionscan be implemented at a room temperature, the preparation raw material is easily obtained, and the preparation method is simple in process, low in energy consumption and relatively low in cost and can realize on-scale popularization and production.

Description

technical field [0001] The invention belongs to the field of preparation of self-repairing materials, and provides a cable material containing self-repairing function composite gel and a preparation method thereof. Background technique [0002] When the polymer matrix is ​​used as a structural material, it is easy to damage both macroscopically and microscopically, and the typical impact damage is caused by microcracks. Microcracks affect various mechanical properties of materials, such as strength, stiffness, dimensional stability, etc., and at the same time affect the thermal properties, electrical properties, and acoustic properties of materials. At the same time, microcracks also provide a place for environmental aging materials, resulting in material degradation and performance. Decline. When polyethylene, silicone rubber, epoxy resin and other polymers and their composite materials are widely used in electrical insulation, micro-defects represented by electric trees a...
