Abstract

The invention relates to the technical field of polymer materials and aims to solve the problem of poor anti-mildew performance of repair agents. For this purpose, the water-based anti-mildew and corrosion inhibitor repair agent for cables of the present invention contains the following raw materials in parts by weight: 5 to 20 parts of quaternary ammonium salt, 5 to 20 parts of chloride, 5 to 20 parts of sterilant, repair agent The carrier is 10 to 40 parts, and the organic aqueous emulsion is 20 to 90 parts. The preparation method of the repair agent of the present invention includes mixing polyvinyl chloride resin, triazine compound, acid absorbent, accelerator, plasticizer, and stabilizer according to any weight ratio, and performing a substitution reaction at 160°C to 200°C. That is, the repair carrier is obtained; add the antifungal agent, silver ammonia solution and nano titanium dioxide to the montmorillonite suspension under high-speed stirring, keep the reaction for 80min to 100min, and dry to obtain the montmorillonite antifungal catalyst; add the above repair carrier and anti-mildew catalyst are added to the water-based acrylic resin and stirred thoroughly to obtain a water-based anti-mildew and corrosion-inhibiting repair agent, which improves the anti-mildew performance of the repair agent.

Description

Technical field[0001]The invention relates to the technical field of polymer materials, and specifically provides a water-based anti-mildew, corrosion-inhibiting repair agent and an anti-oxidation method for cables.Background technique[0002]In order to enhance the ability of cables and other materials to resist moisture, mold and algae in high temperature, high humidity, marine climate and other harsh environments, and to protect the reliability and service life of electrical insulating materials, a layer is usually coated on their surface Antifungal agent or antifungal coating. The general anti-mold agent has weak adhesion to the substrate of the material to be protected, and it is easy to lose effectiveness after environmental impact, and the protection period is short. Even if the anti-mildew coating contains cross-linked structure resin, the anti-mildew performance of the coating will be greatly reduced due to the penetration of moisture, the dissolution and exudation of anti-mi...
