Description
Technical field
The present invention relates to chemical field, more particularly to organic compound, more particularly to solvent, particularly a kind of environment-friendly type
Fire-retardant solvent cleaner and preparation method thereof.
Background technology
Environmental protection and the two principal themes that product safety is that world today's product is used, are weighed by increasing country
Depending on.And in industrialized production, cleaning is the indispensable process procedure in being processed, assembling, storing and repairing.By
It is quite big in the output of every profession and trade, therefore the workload and the usage amount of cleaning agent to this kind of cleaning are also quite big, so as to lead
A large amount of discharges of discarded cleaning agent are caused, what solvent cleaner was conventional currently on the market is not fire-retardant agent for carbon hydrogen detergent and halogenated hydrocarbons
Cleaning agent, some have also applied for patent of invention, and what such as 200810168534.X and 200710151158.9 was used is exactly carbon
Cleaning agent.Agent for carbon hydrogen detergent subject matter is that cleaning force is poor, inflammable and explosive, using dangerous, and metal parts surface is easy
Dissolvent residual.Although and halogenated hydrocarbons cleaning agent using than carbon cleaning agent safety, cleaning performance is also superior to agent for carbon hydrogen detergent, halogen
Harmful to environment and human body for hydrocarbon cleaning agent, such as representative products dichloromethane, trichloro ethylene and tetrachloro-ethylene not only break up air
Ozone layer, and can be harmful to human body psychiatric system and skin, now majority state is prohibitted the use of in plain text in the world, both products
Seriously it is not suitable with market development demand.Therefore researching and developing this environmental-protection flame-retardant solvent cleaner is just quite necessary, and
And with wide market application foreground.
The content of the invention
It is an object of the invention to provide a kind of environmental-protection flame-retardant solvent cleaner, described this environmental-protection flame-retardant solvent
Cleaning agent to solve cleaning agent of the prior art it is not fire-retardant, using it is dangerous, easily to human body and the skill of environmental pollution
Art problem.
This environmental-protection flame-retardant solvent cleaner of the present invention, is made up of, institute cleaning host, azeotropic solvent, cleaning additive

The present invention is reacted, by one using cleaning host and azeotropic solvent under certain temperature, pressure, speed conditions
The fixed reaction time, a kind of nontoxic fire-retardant azeotropic compound of binary of generation, 82 ± 2 DEG C of the azeotropic compound product boiling point, just
A little 86 ± 2 DEG C are evaporated, 112 ± 2 DEG C are done, volatile performance is better than trichloro ethylene, and safety non-toxic, then by azeotropic compound and clearly
Auxiliary compound is washed, in specific temperature, pressure, speed conditions recombination reaction, by the regular hour, a kind of environmental protection resistance of generation
The solvent cleaner of combustion.
Advantages of the present invention is as follows：
1. preferable cleaning performance is reached under conditions of room temperature, with strong detergency, cleaning performance is better than hydrocarbon cleaning
Agent and halogenated hydrocarbons cleaning agent.
2. this product is fire-retardant, anti-riot superior performance, safe and reliable, is significantly better than agent for carbon hydrogen detergent and is cleaned with halogenated hydrocarbons
Agent.
3. this product can also reduce the corrosivity to equipment, and cleaned metal parts should not get rusty.
4. cleaning equipment is simple and convenient, can be used for soaking and washing and ultrasonic wave cleaning.
5. product cleaning is applied widely, it is adaptable to the cleaning of auto parts machinery, bearing, rubber, electronic product etc..
6. product is not remained, and cleaning is simple, and cleaning agent is recycled well.
