Description
Technical Field
The invention relates to the field of engines, in particular to a multifunctional engine line protective agent.
Background
The engine cabin is subjected to high temperature, severe cold, rain, moisture and sand storm, and the phenomena of aging and even cracking of the wire harness, the sensor joint, the rubber hose and the like in the engine cabin occur over time, which is more obvious for old vehicles. These aged circuits are highly susceptible to spontaneous ignition once they are short-circuited by oxidation.
The conventional engine wiring harness is generally composed of a plurality of strands of copper flexible wires, and the outer surface of the copper flexible wires is wrapped by plastic. In daily running, the cabin temperature is very high, and the plastic on the surface of the wire harness releases chemical substances such as plasticizers and the like after being heated, and the substances react with copper wires in the wire harness to reduce the strength of the plastic, increase the resistance of the copper wires and finally cause the wire harness to age to generate short circuit. The rubber hose in the engine room belongs to unsaturated macromolecular hydrocarbon, and the rubber is easy to oxidize after aging to cause vehicle spontaneous combustion.
Graphene oxide is a novel carbon material with excellent performance, and composite materials of the graphene oxide comprise polymer composite materials and inorganic composite materials, and further have wide application fields. The graphene oxide has a small-size effect, and the stacking of the sheets can form compact physical isolation, so that the graphene oxide has strong barrier capability on small molecules and repairs fine cracks. After the product is used, a layer of protective film can be formed on the surfaces of the engine wire, the battery joint and the wire harness, so that moisture is isolated and oxidation is avoided. The product has the characteristics of high pressure resistance and insulativity, so that the aging and cracking of rubber and plastic pipes in the engine room can be delayed, and the electric leakage of the wire harness caused by aging can be prevented. In addition, the sprayed protective film is not easy to be dusty, and the cabin can be kept clean for a long time by being easy to wipe.
The current patents for protecting engine circuits are few, and the Chinese patent of invention (publication No. CN101177588A) discloses a method for manufacturing an engine circuit protective agent, wherein phenolic resin or alkyd resin is used as a film-forming substance, and the phenolic resin is a resin with poor weather resistance and is easy to crack and fall off in the cold north in winter. The alkyd resin is not resistant to acid and alkali and hydrolysis, and the protection time is short, so that the effect is influenced. The resin with more excellent weather resistance, acid and alkali resistance and hydrolysis resistance is adopted, and the resin can not be re-adhered in hot summer and can not crack in cold winter after being used, so that the lines around the engine can be protected for a long time all the year round, and the aging of the lines can be delayed.
