Multifunctional environmental-friendly recyclable hydrocarbon detergent

Abstract

The invention relates to a detergent, in particular to a multifunctional environmentally friendly recyclable hydrocarbon detergent used in a novel vacuum recycling hydrocarbon cleaning machine. The detergent comprises the following components in parts by weight: 50-60 parts of C11H24, 30-40 parts of C12H26 and 5-10 parts of alcohol ether compound or C5-C7 isomeric alcohol. The hydrocarbon detergent has the advantages that residual greasy dirt, moisture, fingerprint, metal dust and other dirts on hardware and plastic parts can be rapidly and effectively cleaned, residues of solder paste, soldering flux and the like also can be cleaned, volatilization speed is moderate, no residue is produced, and the detergent can be recycled in an appropriate pressure relief device, has longer service life and economy compared with a hydrocarbon detergent used in the current market, is not toxic or harmful to human body and is a non-ODS (ozone-depleting substance) product, thus the hydrocarbon detergent is the optimal substitute of the traditional Freon, halohydrocarbon solvent and common hydrocarbon detergent.

Problems solved by technology

[0002] Traditional solvent-based cleaning agents are currently the most widely used ordinary hydrocarbon cleaning agents and halogenated hydrocarbon cleaning agents. Halogenated hydrocarbon cleaning agents include dichloromethane, chloroform (chloroform), trichloroethane, Chlorethylene, tetrachloroethylene, carbon tetrachloride, trifluorotrichloroethane (F-113), etc., because of their strong cleaning ability, non-flammability, fast drying, and distillation recovery, etc., but they will also be used It brings many dangers to people, objects to be cleaned and the environment: 1. Toxicity issues: The above solvents are very toxic except for trifluorotrichloroethane (F-113) and trichloroethane, and can be contacted through skin and breathing Or eating by mistake can cause liver, kidney, and blood poisoning, dizziness and vomiting in mild cases, and shock or even death in severe cases; and some solvents can also produce extremely toxic phosgene under sunlight exposure, which has carcinogenic effects

2. Corrosion problem: Most halogenated hydrocarbon cleaning agents contain chlorine atoms, which will decompose under certain conditions to produce hydrochloric acid, which will corrode equipment and metal workpieces; and most chlorinated hydrocarbon solvents will dissolve, swell, and Deformation or embrittlement, which limits the range of cleaning

3. Evaporation loss: All are volatile liquids with low boiling point (generally 40-80 degrees Celsius). About 40% of the cleaning agent is lost due to evaporation during transportation, storage and use.

4. Environmental pollution problems: chlorinated hydrocarbon solvents cannot be degraded naturally, and will cause serious pollution to air, water and soil after discharge

5. Destruction of the ozone layer: the volatile gases of trifluorotrichloroethane (F-113), trichloroethane, and carbon tetrachloride stay in the atmosphere, rise with the air flow, and decompose to produce chlorine atoms in the stratosphere by ultraviolet radiation. As a catalyst, the chlorine atom can cause a long-term reaction that damages the ozone layer, reducing the ozone layer's ability to block ultraviolet rays, and causing harm to people, animals, and plants on the earth.

Therefore, most industries have restricted the use of this type of solvent, and their prices have gradually increased in recent years, and they have long since lost their dominant position in the cleaning industry

[0003] Ordinary hydrocarbon cleaners only have good dissolving power for oily dirt, but poor cleaning power for water-based dirt and fingerprints; secondly, ordinary hydrocarbon cleaners generally use hydrocarbons with lower boiling points and faster volatilization speeds. Fast, low flash point, large volatile loss, and low safety performance; thirdly, due to the limitation of refining degree, ordinary hydrocarbons have low purity, wide rectification process, wide carbon number distribution, and unstable structure. After distillation recovery, not only recovery The rate is low, and the detergency drops significantly, which almost loses the meaning of recycling, so it cannot meet the demand of the market
