A multifunctional engine circuit protection agent

Abstract

The invention relates to the field of engines and particularly relates to a multifunctional engine circuit protectant. The protectant is prepared through uniformly mixing the following materials in parts by weight: 30-60 parts of ethylene glycol ethyl ether, 20-30 parts of insulating resin, 0.3-0.5 part of OP emulsifier, 0.1-0.2 part of ethyl orthosilicate, 0.5-1 part of graphene oxide, 10-20 parts of propane and 10-20 parts of butane. The protectant is prepared through uniformly mixing the ethylene glycol ethyl ether, the insulating resin, the OP emulsifier, the ethyl orthosilicate and the graphene oxide at normal temperatures, pouring the mixture into a metal gas mist tank, and then inflating the metal gas mist tank with the propane and the butane. The engine circuit protectant has the functions of isolating moisture, avoiding oxidation, resisting high pressure, insulating and delaying circuit aging, repairing fine cracks, keeping clean and the like.

Description

technical field [0001] The invention relates to the field of engines, in particular to a multifunctional engine circuit protection agent. Background technique [0002] The engine cabin has to experience high temperature, severe cold, rain, humidity and wind and sand throughout the year. Over time, the wiring harness, sensor connectors, rubber hoses and other parts in the cabin will age or even crack. For those old cars, this is the case. more obvious. Once these aging lines are oxidized and short-circuited, they are very easy to cause spontaneous combustion. [0003] Common engine wiring harnesses are generally composed of multiple strands of copper flexible wires, and the exterior is wrapped in plastic. The cabin temperature is very high during daily driving, and the plastic on the outside of the wiring harness will release chemical substances such as plasticizers after being heated. These substances will react with the copper wires inside the wiring harness, resulting in...

Problems solved by technology

[0005] At present, there are still few patents for protecting engine circuits. The Chinese invention patent (publication number CN101177588A) mentions a method for manufacturing engine circuit protection agents, in which phenolic resin or alkyd resin is used as a film-forming material, and phenolic resin is a weather-resistant Poor resin, easy to crack and fall off in the cold north in winter

Alkyd resin is not resistant to acid and alkali and hydrolysis, which will lead to short protection time and affect the effect
