The present invention relates to a metal corrosion protection method for aerosol products. Aerosol products are generally made by dispersing the desired main component and subcomponents in water, alcohol, or other organic solvent by dissolving or suspending them, and then placing this and liquefied or compressed gas as a propellant in an airtight container. However, when metal containers are used, corrosion often occurs, deteriorating the quality of the aerosol product, and further reducing the strength of the container itself, which may lead to bursting, thereby maintaining product value. Not only is this impossible, but it often poses a safety problem. Further, for example, when the aerosol product is a coating product such as paint or an adhesive, it is natural that it is necessary to prevent corrosion when used on metal. As a method for preventing metal corrosion in such aerosol products, attempts have been made to add various anticorrosive agents, and a number of substances have been proposed, but there are few that have significant effects. In particular, when halogenated hydrocarbons such as chlorinated hydrocarbons, fluorinated hydrocarbons, and chlorinated fluorinated hydrocarbons are used as propellants, there have been many efforts to prevent corrosion caused by decomposition due to moisture and other influences. Not only are there few products that are fully satisfactory in this area, but recently, due to the so-called regulations on fluorocarbons in the United States, attempts to use propellants other than halogenated hydrocarbons have increased, and for example, the use of dimethyl ether as a propellant has increased. Although various attempts have been made, it has been difficult to establish a metal corrosion prevention method because corrosion often occurs in this case, especially when water is present in aerosol products, and corrosion is also observed in the gas phase inside the container. desired. Among these corrosion prevention methods, the present inventors investigated various corrosion prevention methods for aerosol products that use dimethyl ether as a propellant and contain water. At least one basic substance (B) Acidic substance (C) A compound having a structure thought to be formed by the reaction of a basic substance selected from ammonia and amines with an acidic substance (D) Amino group and substituted amino An effective method is to add a compound selected from the four groups of amphoteric organic compounds having a basic group and an acidic group selected from the group so that the acidic equivalent is equal to or less than the basic equivalent and does not become zero. It was discovered that metal corrosion can be prevented. That is, the present invention was achieved by discovering the unexpected fact that a great metal corrosion prevention effect can be obtained by using a basic substance together with an acidic substance that is thought to promote metal corrosion. In the present invention, a method of simultaneously adding a basic substance selected from ammonia and amines and an acidic substance in an amount equivalent to or less than this basic substance to an aerosol product, and a base selected from ammonia and amines. A method of adding to an aerosol product a compound having a structure that is thought to have been formed by the reaction between a basic substance and an acidic substance in an equivalent or smaller amount, and a basic substance selected from amino groups and substituted amino groups. A method is mainly used in which an amphoteric organic compound having an acidic group in an amount equivalent to or less than the basic group is added to the aerosol product. How to use these compounds in combination, how to add them to aerosol products, and how to create a structure that is thought to result from the reaction between a basic substance selected from ammonia and amines and an acidic substance that exceeds the equivalent of this basic substance. A basic substance selected from ammonia and amines, ammonia and Compounds that have a structure that is thought to result from the reaction between a basic substance selected from amines and an acidic substance in an amount less than the equivalent of this basic substance, and basic groups selected from amino groups and substituted amino groups. and an amphoteric organic compound having an acidic group equal to or less than the equivalent of the basic group, and are selected and added so that the overall acidic equivalent is equal to or less than the basic equivalent and does not become zero.

In addition to the above-mentioned various acidic substances, examples of acidic substances when using a compound having a structure that is considered to be a reaction between a basic substance and an acidic substance include methyl chloride, ethyl chloride, which can form salts with ammonia or amines, Although the existence of organic halides such as lauryl chloride, stearyl chloride, benzyl chloride, and free acids such as thiosulfuric acid is not known, those that exist as salts are also included in the acidic substances.

Or N-alkyl, N-cycloalkyl and N-allyl substituted products of each of the above compounds such as p-methylethylaminophenol. The amount of the additive used in the present invention is suitably 0.0001 to 10% by weight, preferably 0.001 to 5% by weight, and more preferably 0.005 to 2% by weight, based on the total amount of the aerosol product. In the present invention, each component of an aerosol product is filled into a container, and when an aerosol product is prepared, additives are added only before, during, after, or at the same time as filling other components.
Alternatively, the additive of the present invention can be placed in a container by pre-mixing with a suitable diluent or any component in the aerosol, and if necessary, it can be carried out by adding an operation to promote mixing with other components. In addition, even when two or more components are used, they can be used individually or both can be mixed in advance and filled into an aerosol container as is or after mixing with a suitable diluent or any component in the aerosol. Most commonly, each additive component is mixed with an appropriate liquid diluent or any liquid component in the aerosol product for the purpose of reducing PH changes in the aerosol component, etc., and then filled into an aerosol container. There are many. The method of the present invention has the following unexpected results: for example, as shown in the examples below, hexamethylenetetramine and formic acid, which did not have a corrosion-inhibiting effect when used alone, exhibited an excellent corrosion-inhibiting effect when used together. It shows the great effect of external factors. The method of the present invention can be applied to various water-containing aerosol products such as homogeneous phase type, emulsion type, and suspension type using dimethyl ether as a propellant. Since dimethyl ether is flammable, it is generally necessary to reduce this flammability in aerosol products that use it as a propellant, and the use of water is the simplest and cheapest method for this purpose.
In this case, since metal corrosion is likely to occur due to the influence of water, the effect of the present invention is significantly greater. Furthermore, the method of the present invention hardly changes physical properties such as PH of aerosol products, and can be applied to aerosol products where PH changes are undesirable, for example. It is also possible to adjust the pH using an appropriate acid or base as necessary. By the method of the present invention, it is possible to significantly reduce the corrosiveness of various aerosol products such as hair sprays, deodorants, and anti-inflammatory agents to metals such as aluminum, tinplate, and iron used in their containers. The present invention will be explained in more detail below with reference to Examples. Example 1 After mixing a specified amount of additives with 53 g of water, ethanol
Add 40g to a 220ml tin aerosol can, then add 40g of dimethyl ether and heat to 45℃.
After being left for 3 months, the presence or absence of rust was observed, and the following results were obtained.
