The present invention relates to a method for preventing metal corrosion in 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, degrading the quality of the aerosol product. Moreover, the strength of the container itself is reduced, causing it to burst, which not only makes it impossible to maintain its commercial value, but also often poses a safety problem. Further, for example, when the aerosol product is a coating product such as paint or an adhesive, it is a matter of course 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, many conventional methods have concerned the prevention of corrosion caused by decomposition due to moisture and other influences when halogenated hydrocarbons such as chlorinated hydrocarbons, fluorinated hydrocarbons, and chlorinated fluorinated hydrocarbons are used as propellants. Even in this area, there are few that are fully satisfactory. Furthermore, recently, triggered by the so-called fluorocarbon regulations in the United States, attempts to use propellants other than halogenated hydrocarbons have increased.For example, various attempts have been made to use dimethyl ether as a propellant, but in particular, in aerosol products. Corrosion often occurs in the presence of water, and in this case corrosion can also occur in the gas phase inside the container, so it is desired to establish a method for preventing it. The present inventors have studied various methods for preventing metal corrosion, and have found that a method of adding styrene derivatives is effective and can prevent metal corrosion.
We have arrived at the present invention. The styrene derivative used in the present invention has the following general formula () (Here, R 1 is a hydrogen atom, a methyl group, a hexyl group,
An amyl group, R 2 is a hydrogen atom, a methyl group, a hydroxymethyl group, an aldehyde group, a carboxyl group, a carboxymethyl group, a carboxyethyl group, or a metal salt of a carboxylic acid, R 3 is a hydrogen atom, a methoxy group, R 4 is hydrogen atom, hydroxyl group, methoxy group,
Indicates an acetoxy group, and neither R 1 R 2 R 3 R 4 is a hydrogen atom. ) is a compound represented by Examples of styrene derivatives used in the present invention include styrene, α-methylstyrene, β-methylstyrene, P-methylstyrene, anethole, isoeugenol, isoeugenol acetate, cinnamic alcohol, cinnamaldehyde, amylcinnamaldehyde, hexylcinnamaldehyde, These include cinnamic acid, various metal salts of cinnamic acid, various cinnamic acid esters such as methyl cinnamate, and mixtures thereof. The amount of styrene derivative used in the present invention is
Although it cannot be stated unambiguously, the appropriate amount is usually 0.0001 to 10% by weight, preferably 0.001 to 5% by weight, more preferably 0.001 to 5% by weight, based on the total amount of the aerosol product.
It is 0.005 to 2% by weight. In the present invention, each component of an aerosol product is filled into a container, and when preparing an aerosol product, a styrene derivative alone or a suitable diluent or a styrene derivative is added to the aerosol product before, during, after, or simultaneously with other components. By a method such as pre-mixing with any ingredient,
This can be carried out by charging the styrene derivative into a container and, if necessary, adding an operation to promote mixing with other components. Also, if necessary, add a suitable acid,
It is also possible to adjust the PH using a base. The method of the invention comprises dichlorodifluoromethane,
Fluorinated chlorinated hydrocarbons such as trichloromonofluoromethane and dichlorotetrafluoroethane; chlorinated hydrocarbons such as vinyl chloride and methylene chloride;
One or two types of liquefied gas such as dimethyl ether
Homogeneous type, emulsion type, using seeds or more as propellant,
It can be applied to various aerosol products such as suspension type. However, it is particularly effective for aerosol products that use water as part or all of the propellant and dimethyl ether. 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, so the effects of the present invention are is significantly large. Hairspray, deodorant,
It is possible to significantly reduce the corrosiveness of various aerosol products such as anti-inflammatory agents to metals such as aluminum, tinplate, and iron used in their containers. The present invention will be explained in more detail with reference to Examples below. Example 1 After mixing a specified amount of additives with 40g of ethanol, water
Add 53g and put it into a 220ml tin aerosol can, then add 40g of dimethyl ether,
Leave it at 45℃ for 3 months and observe whether rust has formed.
I got the following results.
