Embodiment 1

[0047] Embodiment 1 car engine circuit special care agent, is made of the compound of following weight percent distribution ratio:

[0048] Ethane 5%, Heptane 62%, Octane 20%, Nonane 7%, Decane 6%.

[0049] Its preparation method is as follows:

[0050] (1) First dissolve heptane and octane into the reaction kettle to preheat at 65°C, add 0.5% phenolic resin, stir to make it dissolve to a transparent state, and cool to room temperature after fully stirring;

[0051] (2) Next, add ethane and nonane and stir thoroughly, then add decane, speed up the stirring speed, and make it fully miscible;

[0052] (3) Finally, add 0.2% ethylene glycol monobutyl ether as a penetrating agent and 0.2% polyether-modified polydimethylsiloxane as an anti-flowing agent, and stir well to obtain the product of the present invention.

Embodiment 2

[0053] Embodiment 2 car engine line special care agent, is made by the compound of following percentage by weight proportioning:

[0054] Ethane 16%, heptane 60%, octane 15%, propane 2.5%, butane 6%, bromane 0.5%.

[0055] Its preparation method is as follows:

[0056] (1) First, dissolve heptane and octane into the reaction kettle to preheat at 75°C, add 1% alkyd resin, stir for 3 hours, make it dissolve to a transparent state, and cool to room temperature after fully stirring;

[0057] (2) After adding butane and ethane, stir fully, then add propane bromide, speed up the stirring speed, and make it fully miscible;

[0058] (3) Finally, add 0.2% ethylene glycol monobutyl ether and 0.2% polyether-modified polydimethylsiloxane, and stir well to obtain the product of the present invention.

Embodiment 3

[0059] Embodiment 3 The application of care agent of the present invention on automobile engine circuit

[0060] Turn off the vehicle and wait for the engine temperature to drop below 50°C. If there is too much grease on the engine circuit, wipe it off with a cloth first, and then spray the canned care agent directly on the engine circuit. A layer will form after a few minutes protective film. And it can be used on all types of engine circuits, internal and external surfaces of the engine, including engine casings, fuses, electronic circuit switches, contacts and battery connectors and other accessories.

[0061] The following is the effect after using the product care agent of the present invention on the car engine circuit in Table 4

Abstract

The invention discloses a special nursing agent for automobile engine lines and a preparation method thereof. According to weight proportion, the agent is prepared by ethane, heptane, octane, nonane and n-decane or ethane, heptane, octane, propane, butane and bromoalkane. The specific preparation method is that: first, the heptane, the octane are dissolved, put into a reaction vessel to be preheated, added with high molecular polymer resin, fully stirred and cooled to room temperature; second, ethane, butane or nonane are added and stirred to be fully mixed; third, penetrating agent and anti-advection agent are added and uniformly stirred, and the product is finally made. The nursing agent of the invention, having been tested, has performances of 100 percent insulation and 51700 volt endurance, and can solve the problems of line aging, cracking and electric leakage; by adopting the invention, a protection film can be formed at the wire layup of all lines of the engine, which avoids invasion by water vapor and moisture, prevents oxidation, lowers noise, reduces engine jitter and decreases engine spontaneous-combustion rate.

Description

a technical field [0001] The invention relates to a chemical composition, in particular to a special care agent for automobile engine circuits. 2. Background technology [0002] With the development of the automobile industry, the role of the on-board circuit system is becoming more and more important. The circuits all over the engine compartment of the car are prone to aging, cracking, and leakage under long-term high temperature, and the circuit connectors have poor contact due to long-term bumps and vibrations. , It is easy to generate electric sparks, and in severe cases, it will cause the engine to spontaneously ignite. Therefore, the maintenance of automobile circuits is very important. [0003] In recent years, with the increase of car ownership, especially the rapid development of private cars, the number of natural car accidents across the country has doubled to more than 8,000 in a year, causing direct economic losses of hundreds of millions of yuan. According to ...
