Example Embodiment

[0030] A preparation method of a high-solid content engine surface heavy oil cleaning agent includes the steps of heating deionized water to 60-80°C, adding other raw materials, and stirring until all components are completely dissolved.

[0031] The cleaning agent of the present invention is formulated under the condition of 60-80°C and can be used at room temperature. Spray the cleaner on the outer surface of the engine cylinder through a hand-button spray gun, soak it naturally for 5-10 minutes, and rinse with tap water to remove stubborn oil stains and carbon deposits attached to the outer surface, restore the original luster of the engine metal surface, and Steel, cast iron, aluminum, copper and other metals are non-corrosive, and the operation is simple, fast and convenient.

Example Embodiment

[0033] Example 1:

[0034] A high-solids engine surface heavy oil cleaning agent, its formula is as follows (mass percentage):

[0035] Sodium hydroxide 2%, sodium metasilicate pentahydrate 6%, silicate stabilizer KM-309 0.6%, urea 0.5%, sodium sulfate 1.5%,

[0036] Benzotriazole 0.2%, Dodecylbenzenesulfonic acid 2.0%, Oleic acid 0.8%, 6501 0.5%, AEO-7 0.4%, OEP-98 0.5%,

[0037] The balance is 4% butyl cellosolve, 6% isopropanol, and deionized water.

[0038] Preparation process: heat deionized water to 70℃, add sodium hydroxide, sodium metasilicate pentahydrate, silicate stabilizer, urea, sodium sulfate, benzotriazole, stir to dissolve all, keep warm at 70℃ , And then add the rest of the ingredients while stirring. After completely dissolved, a light brown to brown transparent liquid is obtained.

[0039] Detergency test: According to the requirements of QB / T 2117 general water-based metal detergent

[0040] The test results are shown in the table below:

Abstract

The invention discloses a high-solid-content engine appearance heavy greasy dirt cleaning agent and a preparation method thereof. The cleaning agent is prepared from the following raw materials in percentages by weight: 0.5-5% of alkali metal hydroxide, 3.0-10% of silicate, 0.3-3.0% of a silicate stabilizer, 0.2-2.0% of urea, 0.5-5.0% of sulfate, 0.1-1% of a metal corrosion inhibitor, 1-5% of an anionic surfactant, 0.5-2% of a nonionic surfactant, 0.1-1.0% of a permeating agent, 2-10% of an organic cosolvent and the balance of deionized water. The preparation method comprises the following steps: heating deionized water to 60-80 DEG C, adding other raw materials and stirring until all components are completely dissolved. The cleaning agent disclosed by the invention has good cleaning effect on the engine appearance and no corrosion too metals such as steel, cast iron, aluminum and copper and is simple in operation, fast and convenient.

Description

technical field [0001] The invention relates to a cleaning agent for heavy oil dirt on the surface of an engine with high solid content and a preparation method thereof. Background technique [0002] After the vehicle has been running for a period of time, it will inevitably be infested with various dust, dust and other dirt. These dirt will combine with the leaked engine oil on the surface of the engine to form a highly viscous pollution mixture. They are affected by the heat generated when the engine is running. Gradually carbonized into heavy dirt such as colloid and oil sludge. [0003] The traditional method of washing with high-pressure water guns or using gasoline and kerosene to clean these heavy dirt is out of date. [0004] General synthetic cleaning agents contain a certain amount of surfactants and detergent builders. Appropriate detergent builders and surfactants have a synergistic effect, which can effectively improve the ability to remove oil. The higher the...
