Abstract

The invention discloses an anti-aging corrosion-proof polyimide coating material, and belongs to the technical field of coating materials. The coating material comprises the following materials in parts by weight: 10 to 50 parts of polyimide, 3 to 10 parts of nanometer silicon, 10 to 20 parts of polysiloxane, 3 to 10 parts of solvent, 2 to 8 parts of fire retardant, 1 to 5 parts of puntia extract and 5 to 10 parts of crofton weed extract. By adding the nanometer silicon, the abrasion resistance of the coating material is improved; and the aging of the coating material after being used for a long time is prevented. By adding the polysiloxane, the thermal insulation of the coating material is improved. By adding the fire retardant, the fire resistance of the coating material is improved. By adding the puntia extract, the radiation resistance of the coating material is further improved; and the anti-fouling performance of the coating material is improved. With the application of the crofton weed extract, a harmful weed utilization way is developed; and the anti-fouling performance of the coating material is enhanced.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an aging-resistant and anti-corrosion polyimide coating. Background technique [0002] With the development of the electrical industry and the improvement of communication cable technology, the demand for polyimide coatings is increasing. Polyimide coatings have the advantages of high temperature resistance and good insulation performance, and are widely used in optical fibers, ships, etc. Housing, communication cables, semiconductors, household appliances and power cables and other industries. [0003] Although polyimide coating has the advantages of high temperature resistance and strong insulation performance, it is easy to age, easily polluted and corroded underwater, and is also easy to be adhered by aquatic animals, destroying the normal use of machine parts, which limits this type of coating. Application of paint. [0004] Cactus is a plant that can grow tenaciously in ...
