Abstract

The invention discloses a high-concentration gasoline detergent and a preparation process thereof. The high-concentration gasoline detergent comprises polyether amine, polyisobutylene amine, di-tert-butyl-p-methylphenol, bis(salicylidene)propane diamine, benzotriazole, xylene, aviation kerosene, n-butyl alcohol, isopropanol and SP demulsifying agents, and the weight percentages of the components are as the follows: 15-25% of the polyether amine, 25-35% of the polyisobutylene amine, 0.5-1% of the di-tert-butyl-p-methylphenol, 0.5-1% of the bis(salicylidene) propane diamine, 0.5-1% of the benzotriazole, 1-10% of the xylene, 15-25% of the aviation kerosene, 3-8% of the n-butyl alcohol, 5-10% of the isooctanol and 2-5% of the demulsifier SP. The preparation process comprises the following steps: step 1, selecting materials; step 2, carrying out mixing; step 3, carrying out concentrating; step 4, adjusting the pH value; and step 5, carrying out discharging. The high-concentration gasoline detergent can be used for replacing other expensive gasoline detergents, the concentration degree is high, the use amount is low, the effect is remarkable, the raw materials are relatively cheap, production cost is greatly saved, sediments at oil nozzles and sediments at air inlet valves can be removed, and meanwhile, formation of combustion chamber deposits (CCD) are reduced, so that secondary pollution of existing detergents is avoided.

Description

technical field [0001] The invention relates to the technical field of gasoline detergent, in particular to a highly concentrated gasoline detergent and a preparation process. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles in our country is increasing rapidly. As automobiles bring convenience to people's production and life, they also increase the consumption of petroleum resources and the emission of harmful exhaust substances. How to keep the car engine in a good working condition for a long time, so that the fuel gasoline can be fully burned, reduce fuel consumption and improve emissions. This must require the fuel intake system of the automobile engine to be kept clean for a long time. For this reason, it is clearly stipulated in the national environmental protection standard that an effective gasoline detergent must be added in motor gasoline. Existing gasoline detergents use solvent oils such as trimeth...
