Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention mainly relates to an improvement in an automobile cleaning agent that cleans an automobile body and imparts water repellency to the automobile body.

(Conventional technology) Traditionally, automobile bodies, tires, etc. (hereinafter referred to as vehicle bodies, etc.)
During cleaning, water and car shampoo were used to remove dirt from the car body. After that, car wax was applied to make the car body water repellent. Therefore, in this case, it is necessary to prepare a cleaning agent and a water repellent separately, which is not only inconvenient, but also very troublesome because both cleaning and waxing operations have to be performed.

Therefore, in view of the above drawbacks, a small amount of alanine is added to a mixture of a small amount of paraffin wax or other waxes, a small amount of silicone oil, a hydrocarbon solvent spirit, and a small amount of additives such as rust preventives. An emulsion-type vehicle wax made by adding an amphoteric surfactant and an appropriate amount of water (
(see Japanese Patent Application Laid-open No. 56-57863) was proposed.

(Problems to be Solved by the Invention) Although the above-mentioned conventional emulsion wax for vehicles has a certain degree of washability and water repellency,
It had the following drawbacks.

■Weak water repellency (particularly poor sustainability). ■It lacks foaming properties and tends to have poor cleaning properties. In addition, this foaming property also has a secondary role of giving the user a feeling of satisfaction during cleaning, so the poor foaming property may be dissatisfying to the user.

Therefore, the present invention was devised, and its purpose is to provide a cleaning agent for automobiles that satisfies all of the requirements of detergency, water repellency, and foaming properties.

(Means for Solving the Problems) The means taken by the present invention to achieve the object described in 1 will be explained below.

First, the automobile cleaning agent according to claim 1 has a composition including at least one of a nonionic surfactant or an amphoteric surfactant;
The product is an automobile cleaning agent characterized by being composed of a liquid mixture whose main components are glycols, water, and amine-modified silicone oil dissolved in these.

Next, the composition of the automobile cleaning agent according to claim 2 is such that the mixed liquid contains N-methyl-2-pyrrolidone and the average particle size is 0.1 to 0.1.
The cleaning agent for automobiles according to claim 1, characterized in that it contains an abrasive of 100 μm.

(Action of the Invention) By the above-mentioned means, first, when the cleaning agent for automobiles according to claim 1 is applied to the body of an automobile and rubbed, it foams in a large amount. The main reasons for this are that this detergent contains at least one of a nonionic surfactant or an amphoteric surfactant, and that it does not contain wax, etc., which tend to inhibit foaming properties. . When the cleaning agent is applied to a car body or the like and rubbed, the dirt on the surface of the car body or the like is easily removed. The main reason for this is that the surface of the vehicle body, etc. is adsorbed by the surfactant contained therein, thereby thoroughly wetting the surface (so-called wet temperature effect).

Furthermore, by using the cleaning agent, water repellency with excellent durability is imparted to the surface of the vehicle body, etc.

This is because the amine-modified silicone oil it contains adheres to the surface of the vehicle body, etc., and the reason why the amine-modified silicone oil has excellent sustainability is that it is not an emulsion, but is solubilized and dissolved in the cleaning liquid. This is thought to be the main factor. Incidentally, the glycols contained in the above-mentioned automobile cleaning agent mainly act as a stabilizer for the cleaning agent.

Next, the automobile cleaning agent according to claim 2, in addition to the effect of the automobile cleaning agent according to claim 1, easily removes stains that are difficult to remove with the same cleaning agent, especially water scale.

This means that the automobile cleaning agent according to claim 2 contains N-methyl-2-pyrrolidone and an abrasive having an average particle size of 0.1 to 100μ in the mixture of the automobile cleaning agent according to claim 1. This is due to being forced to do so. In other words, this N-methyl-2-pyrrolidone acts to remove dirt, etc. from the surface of the car body, etc., and the abrasive acts to polish the surface of the car body, etc. .

(Example) The present invention will be described in detail below based on Examples, but these are representative examples that are considered to be the best, and the present invention is not limited to these Examples. .

A conventional example is also shown for comparison with this example.

Hereinafter, in this example, polyoxyethylene (10 mol) nonylphenyl ether (concentration 100%), dimethyl lauryl amine oxide (concentration 33%), and distearyl polyethylene glycol were employed as nonionic surfactants.

Next, as the amphoteric surfactant, dimethylalkylbetaine (concentration 36%) was used, but in addition to this, alkylamidoacetic acid betaine, imidazolinium betaine, etc. may be used.

Next, although ethylene glycol was used as the glycol, propylene glycol, glycerin, etc. may also be used.

Next, the abrasive has an average grain size of 4. Although Oμ diatomaceous material is used, other materials such as alumina, silica, calcium carbonate, etc. may also be used. Moreover, this average particle size is 0.1 to 10
It is sufficient if it is within the range of 0μ.

The reason why the average grain size was limited to the range of 0.1 to 100μ is as follows.
If it is less than 0.1μ, the grain size is too small and the polishing effect is small.
This is because the effect of removing dirt (particularly water scale) on the surface of the vehicle body, etc. is small. On the other hand, if it is 100μ or more, it is too large and may damage, for example, the smooth and glossy surface of a car body.

Next, although it is not an essential component of the present invention, a thickener may be added to the automobile cleaning agent in order to adjust the viscosity as necessary.

The water repellency of each sample (B in the table) to which water was continuously applied with a hose for minutes was visually determined. The symbols for this judgment are: ◎: Small water droplets are uniformly formed on bonnet 2, ○: Slightly thick water droplets are uniformly formed on bonnet 2, △: Water is spread over a wide area on the bonnet. Water adheres uniformly, × indicates that water adheres to almost the entire surface of the bonnet.

(The following is a blank space) From the table above, it can be seen that the automobile cleaning agents according to Examples 1 to 3 are excellent in all of the cleaning properties, foaming properties, and water repellency. The reason for this is as described in the section on the effects of the invention.

In comparison, among the conventional examples (1 to 3), conventional example 1 has good cleaning properties, foaming properties, and water repellency after light washing with water (
Although A) in the table shows good results, 15
Poor water repellency (B in the table) after water spraying for minutes. This is considered to be due to the use of an emulsion type amine-modified silicone oil. Next, conventional example 2
In particular, foaming properties are poor. One of the reasons for this is that Conventional Example 2 contains paraffin wax and spirit, which tend to inhibit foaming properties.

Conventional Example 3 has good cleaning properties, but is poor in foaming properties and water repellency. This is because it contains liquid paraffin and ethylene glycol monobutyl ether, which tend to inhibit foaming properties, and polyoxyethylene alkylamine and liquid paraffin, which tend to inhibit water repellency. There is one.

(Effects of the Invention) As explained above, the present invention provides the following effects.

First, when the cleaning agent for automobiles according to claim 1 is soaked in a sponge or the like and rubbed on the body of an automobile, dirt is removed easily due to its excellent cleaning properties.

- Since it has excellent foaming properties, users can feel satisfied when using it during cleaning work.

■In addition to the cleaning effect described above, it also has excellent water repellency, so there is no need for further waxing after cleaning, and the water repellent effect lasts well, making it possible to reduce the number of times waxing is required. .

Next, the automobile cleaning agent according to claim 2 contains N-methyl-2-pyrrolidone, which is strong in removing stains, and an abrasive in the mixed liquid of the automobile cleaning agent according to claim 1. ,
