Description

Special caring agent for automobile engine lines and preparation method thereof

One technical field

The present invention relates to a kind of chemical composition, specifically relate to a kind of nursing agent of automobile engine line special use.

Two, background technology

Along with developing of automobile industry, the effect of vehicle-mounted Circuits System is more and more important, the circuit that is abound with in automobile engine nacelle wears out, chaps, causes electric leakage easily under long-time high temperature, terminal comes in contact bad because of the vibrations of jolting for a long time, easily produce electrical spark, can cause engine auto-ignition when serious, therefore, the automobile circuit maintenance is extremely important.

In recent years, along with the increase of automobile pollution, the especially fast development of private car, national automobile natural accident rises at double and reaches more than 8000 in 1 year, causes the several hundred million units of direct economic loss.According to the fire department statistics, in the majority in the natural accident with car, account for more than 80%, reason is all caused with wire short-circuiting.Analysis expert, private car quantity increases year by year, and car owner's prevention awareness is thin, and many car owners do not understand automobile circuit general knowledge, ignore line service, and this has become the weak link of Motor Maintenance maintenance.

Be the season occurred frequently of automobile generation incidents of spontaneous combustion summer, temperature height, high humidity, engine radiating are slow, temperature in the bonnet is up to more than 80 ℃, in case line electrical leakage, very easily take place from dying accident, the self-burning of vehicle accident takes place hundreds of more than in April according to the statistics made by the departments concerned altogether, the expert reminds, and the automobile engine line maintenance is very urgent.But, also do not have the care products of engine line special use in the market.

Three, summary of the invention

The object of the present invention is to provide nursing agent of a kind of automobile engine line special use and preparation method thereof, the electric leakage problem can not take place, the engine auto-ignition problem can not take place by the automobile engine line after the nursing agent nursing.

The objective of the invention is to realize by following technical scheme:
