preparation example Construction

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

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

Embodiment 1

[0034] A high-solid-content cleaning agent for heavy oil stains on the surface of an engine, the formula of which is as follows (mass percentage):

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...
