Description

Industrial cleaning agent and its manufacturing method {DETERENT COMPOSITIONS FOR INDUSTRIAL USE AND PREPARING METHOD THERE OF}

The present invention relates to a method for manufacturing an industrial detergent for removing and dissolving grease or oil stains and the like, and to a detergent, in particular dichloropropane, dichlorofluoroethane, stabilizer, additive, activator and chlorine trapping agent. The present invention relates to an industrial cleaner and a method for manufacturing the same, which provide a composition such as a solvent and a solvent that are not environmentally friendly and do not have a risk of ignition and explosion by not containing volatile organic materials.

In general, the industrial cleaning agent of the present invention is a cleaning agent for removing stains of grease, oil, and the like.

Therefore, such a detergent is also used simultaneously as a solvent for dissolving the hardened grease or oil.

However, most of the industrial cleaners and solvents produced and sold in Korea at this time are imported by water-based cleaners such as Trichloroethylene <TCE>, Perchloroethylene <PCE>, Methylenechloride <MC>, Freon, etc. .

However, these materials (TCE, MC, PCE, Freon) contains volatile organic substances (VOC), is not environmentally friendly, and has the disadvantage of flammability and explosion.

Therefore, in order to compensate for this disadvantage, the present invention selected a dichloropropane-based solvent.

Dichloropropane-based composition does not contain a volatile organic material (VOC) is not only environmentally friendly, but also stable to reduce the risk of ignition and explosion.

In addition, there is almost no water solubility, which prevents the mixing of moisture due to humidity during the process to reduce the occurrence of bubbles, or as the solids dissolving power increases, the productivity is improved, and the higher the dissolving power than water-based cleaners and compliant cleaners for cleaning oils and rust preventive oils. Excellence allows for increased workability and productivity.

Now look at the problems of the conventional industrial cleaner more deeply.

The composition used in the cleaning agent and the solvent is generally composed of a solvent, a stabilizer, an enhancer and other additives, the conventional TCE, MC, PCE, Freon has been used as a solvent, the TCE, MC, PCE, Freon is an atmospheric environment According to the Conservation Act, it is defined as VOC (Volatile Organic Compound). If it is used continuously, additional measures should be taken to suppress VOC emissions.

That is, TCE, MC, PCE, and Freon are volatile organic chemicals and are easily evaporated into the atmosphere due to their high vapor pressure. Secondary effects such as ozone and PAN (Peroxyacetyl Nitrate) are caused by the photochemical reaction by the action of sunlight when they coexist with nitrogen oxide in the atmosphere. It generates pollutants and induces photochemical smog. If this material is used as a solvent, it is necessary to install separate emission control, recovery and prevention facilities. Therefore, there are various problems such as excessive facility investment.

In addition, when TCE, MC, PCE, and Freon are used as solvents for cleaning agents and solvents, TCE, MC, PCE, and Freon are highly flammable and explosive substances, which may cause storage problems such as fire. Has been required.

Therefore, alternative cleaners and solvents for TCE, MC, PCE, Freon have been developed, and solvents and solvents using water as a solvent.

However, since the resin is not soluble in water, alkali has been added to about 40-50% of the amount of resin to transform the water into an alkaline solvent, and the resin is dissolved in water by saponifying the resin by reaction of alkali and resin. Some may not dissolve depending on the type of resin.

In addition, it takes not only a long time to dissolve the resin in water, but also when applied as a detergent and a solvent, due to the soapy nature of the resin, there is a problem that the bubbles remain after mixing the detergent and the solvent is forced to foam by spraying.

However, even in the case of applying the cleaning agent and the solvent by spraying, it is not preferable because a long time is required for the bubbles to disappear.

Furthermore, by using water as a solvent, the surface tension is increased, and thus the wettability is lowered and it is difficult to uniformly apply the surface.

The present invention, which solves the above problems, relates to a method for manufacturing an industrial detergent for removing and dissolving grease or oil stains and the like, and in particular, to dichloropropane, dichlorofluoroethane, stabilizers, additives, active agents and chlorine capture. Industrial cleaning agent and its manufacture to provide a cleaning agent and solvent composition that is not only harmful to the human body but also harmful to human body and does not contain volatile organic substances by preparing and cleaning the detergent by adding and mixing the agent. To provide a method.

Accordingly, the present invention provides a method for preparing an industrial cleaner for dissolving and dissolving grease or oil, and the like, comprising: 40-95% by weight of dichloropropane as a liquid substance based on the total mass; Mixing 1-58% by weight of dichlorofluoroethane; Second step: optionally, one or two or more of the stabilizers of the group of 2-methoxyethanol, 1,3-cyclohexadiene, 1,5-hesadiene, 1-chloropropane, cyclohexene, the substance of the solution Mixing and dissolving 0.01-0.1% by weight of the additives, 0.01-0.1% by weight of the active agent, and 0.01-1% by weight of the chlorine trapping agent, to 1-10% by weight of the mixed stabilizer; The third step: To provide a method for manufacturing an industrial detergent comprising a step of mixing the solution obtained through the first step and the solution obtained through the second step to remove the stains such as grease or oil.

In addition, the additive introduced in the second step of the present invention, 3-boron fluoride ethyl amide complex or palmitic acid may be used; The active agent is butyl amine hydrofluoric acid, butyl amine hydrochloride, ethyl amine hydrofluoric acid, pyridine hydrofluoric acid, cyclohexyl amine hydrofluoric acid, ethylamine hydrochloride, 1,3-diphenyl guanidine hydrochloride, 2, An object of the present invention is to provide a method for preparing an industrial cleaner that can be used by selectively adopting one or two or more from the group consisting of 3-dibromo-1-propanol.

In addition, the present invention is to provide an industrial cleaner prepared through the above-described manufacturing method in the industrial cleaner for removing and dissolving grease or oil stains and the like.

The present invention relates to an industrial detergent production method for removing and dissolving grease, oil stains and the like.

Therefore, the preparation method and the cleaning agent will be described in detail with the table shown.

In the present invention, a method for preparing an industrial detergent for dissolving and dissolving grease or oil, and dissolving the same, comprising 40-95% by weight of dichloropropane and 5-60% by weight of dichlorofluoroethane based on the total mass. Mixing prepares the detergent.

It is simply produced by mixing the liquid dichloropropane and dichlorofluoroethane.

In the present invention, an industrial detergent for removing and dissolving grease or oil stains, and dissolving a mixture of 40-95% by weight of dichloropropane, which is a liquid substance, and 5-60% by weight of dichlorofluoroethane, based on the total mass. And the cleaning agent itself produced is also subject to the patent.

Hereinafter, the cleaning agent according to the present invention and a manufacturing method thereof will be described in detail.
First, to prepare the cleaning agent of the present invention, the first step: 40-95% by weight of dichloropropane, which is a liquid substance, based on the total mass; 1-58% by weight of dichlorofluoroethane is mixed.

And step 2: selecting one or two or more of the stabilizers of the group of 2-methoxyethanol, 1,3-cyclohexadiene, 1,5-hesadiene, 1-chloropropane, cyclohexene, which are substances of the solution 1-10% by weight of the stabilizer mixed with 0.01-0.1% by weight of the additives of the solid material, 0.01-0.1% by weight of the active agent and 0.01-1% by weight of the chlorine trapping agent is mixed and dissolved.

In addition, the third step: consisting of mixing the solution obtained through the first step and the solution obtained through the second step to prepare a cleaning agent to remove stains such as grease or oil.

That is, in order to produce the industrial detergent, the solvent, etc. which are used for the washing | cleaning and solvent process of this invention, it consists of an additive, an active agent, and a chlorine trapping agent formed from dichloropropane, dichlorofluoroethane, stabilizer, solid content.

More specifically, the present invention adds 40-95% by weight of dichloropropane and mixes 1-58% by weight of dichlorofluoroethane (141B).

And 1-10% by weight of stabilizer, 0.01-0.1% by weight of additive, 0.01-0.1% by weight of active agent and 0.01-0.1% by weight of chlorine trapping agent are added and compounded.

Herein, both the dichloropropane and dichlorofluoroethane are liquid compounds.

At this time, the present invention uses dichloropropane as a basic solvent, this material does not require a separate treatment process, etc., suppresses the risk of flammability and explosion, and at the same time, further improved cleaning agent and solvent when treating the cleaning agent and solvent Can be provided.

That is, as the basic solvent dichloropropane, each of the dichloropropane isomers may be used, and a mixed composition of the dichloropropane isomers may also be used.

And this dichloropropane is used 40-95 weight%.

Here, the characteristics of dichloropropane are described as stable chlorine compounds and are not defined as volatile organic substances.

It is also environmentally friendly and reduces the risk of fire due to suppression of flammability and explosiveness.

In addition, when the evaporation rate is applied to the cleaner and the solvent, the energy is reduced during preheating and there is little solubility of water, thereby preventing the mixing of moisture due to humidity during the process, thereby improving paint and coating.

In addition, since dichloropropane has a high dissolving power, the washing agent and the solvent prepared therein increase the washing power and the dissolving power.

As a result, productivity is improved and workability and productivity can be increased because water and rust preventive oils are superior to water-based cleaners and oil-based cleaners.

Of course, such an increase in the input amount of dichloropropane brings about an enhanced cleaning power.

However, when chlorine of dichloropropane is present as a single substance, chlorine not only corrodes metals but also acts as a toxic substance, and thus has a disadvantage in that carbon-chlorine chains are broken due to chemical reactions caused by temperature and humidity generated during cleaning and solvent operations. Do.

Of course, in the present invention it is used by adding a stabilizer to prevent this.

As will be described later, this stabilizer is also intended to easily dissolve additives, activators, chlorine trapping agents, but is also used to prevent corrosion, and to prevent discoloration and deterioration.

And dichlorofluoroethane of the next structure is a boiling point control agent.

That is, in the first step of the preparation of the cleaning agent in the present invention, dichlorofluoroethane, which is the boiling point control agent, is added to the dichloropropane, which is the basic solvent, for compounding.

More specifically, the dichloropropane has a boiling point of about 70-120 ° C., which is higher than that of conventional TCE, MC, PCE, and Freon, and thus the dichlorofluoroethane having a low boiling point in consideration of the drying rate of the product (cleaning material). Used as an azeotrope with a boiling point regulator.

At this time, the amount of dichlorofluoroethane mixed with dichloropropane (40-95% by weight) showing an azeotropic point is 1-58% by weight.

The dichlorofluoroethane used as the non-point control agent is used as a non-flammable to further suppress the flammability of the flame retardant dichloropropane to contribute to the stabilization of dichloropropane.

And next, the present invention is a stabilizer of the group of 2-methoxyethanol, 1,3-cyclohexadiene, 1,5-hesadiene, 1-chloropropane, cyclohexene in the preparation step 2 1-10% by weight of one or more selective stabilizers are mixed with 0.01-0.1% by weight of the additives, 0.01-0.1% by weight of the active agent and 0.01-1% by weight of the chlorine trapping agent.

That is, one or two or more of the stabilizers in solution formed of 2-methoxyethanol, 1,3-cyclohexadiene, 1,5-hesadiene, 1-chloropropane, and cyclohexene groups may be mixed to form one stabilizer. Its weight is made from 1-10% by weight.

Then, the additives, activators, and chlorine trapping agents formed as solids are mixed and dissolved in the stabilizer thus prepared.

Then, where it is used as the additive, there is a 3-boron boron fluoride ethyl amide complex or palmitic acid.

This additive is used to prevent icicle formation and to give gloss or matteness during cleaning operations and solvent operations.

In the case of the active agent, the wettability or fluidity during the cleaning operation and the solvent operation of the detergent and the solvent to be prepared is used to compensate for this.

In addition, the use of the active agent improves the cleaning agent and the solvent and prevents ionization of compositions such as the cleaning agent and the solvent.

And as an active agent, as described above, butyl amine hydrofluoric acid, butyl amine hydrochloride, ethyl amine hydrofluoric acid, pyridine hydrofluoric acid, cyclohexyl amine hydrofluoric acid, ethylamine hydrochloride, 1,3-diphenyl guanidine fluoride In the group consisting of hydrochloride, 2,3-dibromo-1-propanol, one or two or more may be selectively adopted and used.

That is, only one of each of the above components may be used, or two or more thereof may be mixed and used.

On the other hand, the chlorine trapping agent, which is another solid substance, is an amine-based and / or ester-based chlorine trapping agent.

That is, this chlorine trapping agent is used in order to prevent corrosion and toxicity by chlorine, and it captures and neutralizes chlorine which exists in an ionic state.

However, when the chlorine trapping agent is used in an amount of less than 0.01% by weight, its role is not sufficiently exhibited, and when used in an amount of 1% by weight or more, it is not preferable because it shows strong alkalinity.

Therefore, it is important to be introduced in the above weight ratio, more specifically diisopropylamine is the most preferred.

Of course, the diisopropylamine is a kind of amine-based chlorine trapping agent.

As a result, an industrial detergent manufacturing method for preparing a detergent for removing stains such as grease or oil of the present invention is completed through three steps of mixing the material of the second step and the solution obtained through the first step.

In addition, the present invention is not only characterized by such a manufacturing method, but also for industrial cleaning agents for removing and dissolving grease, oil stains, etc., industrial cleaning agents manufactured through all the above-mentioned manufacturing methods are also subject to the claims.
