Environment-friendly deposited carbon cleaning agent and preparation method thereof

Abstract

The invention discloses an environment-friendly deposited carbon cleaning agent and a preparation method thereof. The deposited carbon cleaning agent is made of raw materials by mass percent: 1-20% ofinorganic alkaline, 1-10% of block polyether surface active agent, 1-10% of fatty alcohol-polyoxyethylene ether, 0.1-10% of esters solvent, 0.1-10% of cosolvent, 0.1-10% of monocyclic dibasic acid and less than or equal to 90% of water. The preparation method comprises: adding the metered tap water and inorganic alkaline into a reaction kettle, stirring until the inorganic alkaline is completelydissolved; then, sequentially adding the fatty alcohol-polyoxyethylene ether, the monocyclic dibasic acid, the block polyether surface active agent, the cosolvent and the esters solvent, stirring for10min when adding one material every time, and finally, stirring the mixed solution to be transparent.

Description

Technical field: [0001] The invention relates to a chemical cleaning agent, in particular to a fast cleaning and environmentally friendly carbon deposit cleaning agent and a preparation method. Background technique: [0002] Carbon deposits are easy to form on piston engines used in automobiles, internal combustion engine trains, ships, and aircraft, resulting in reduced power performance of the engine and increased fuel consumption. The reason for the formation of carbon deposits is that the fuel and its combustion products decompose and adhere to the engine at high temperature. If the high temperature lasts for a long time, the paint film will further decompose and generate carbon black on the outer surface. Cleaning is different from the cleaning of general oil stains. It needs to have a good penetration, dissolution and stripping effect on the varnish. There are mainly two types of carbon deposit cleaners on the market, one class is the automobile engine interior cleane...

Problems solved by technology

There are mainly two types of carbon deposit cleaners on the market, one class is the automobile engine interior cleaner announced by CN1232097 as the Chinese Patent Publication No. Composed of volatile solvents, although this type of carbon deposit cleaning agent has a fast cleaning speed and obvious effect, it has the problems of seriously endangering the health of the operator and causing great pollution to the environment during use; there is also a class of Chinese patent publication No. CN1480517A announces that the engine avoids dismantling carbon agent, mainly is based on surfactant, although it has no irritating smell, is more environmentally friendly and has little damage to human body, but its decontamination ability is relatively poor, not only cleaning speed is slow but also on the carbon deposit dirt. The paint removal effect is not obvious, and there are still many residual carbon deposits after cleaning that need to be manually removed, which increases labor costs and reduces work efficiency
