DESCRIPTION

COMPOSITION TO CLEAN BODIES, RINGS, ENGINES AND VEHICLE ACCESSORIES, WITHOUT DAMAGING THE PAINT AND METHOD OF

PREPARATION

TECHNICAL FIELD

The present invention is related to the technical field of automotive cleaning products, specifically to a composition to clean the paint of the bodywork, accessories, rings and engines of all types of vehicles and its preparation method.

STATE OF THE ART

The invention of this product arose because in the jungle there are many places that are not paved, where people who have farms walk and in order to enter each place mentioned, you have to go through places where there is a lot of mud and earth. This makes each after vehicle transit through these _s places back to town full of mud and heat engines, the mud gets stuck on the surface and not only the engines, it also affects the rings and any surface metal and plastics. The usual technique is to perform a wash (such as a motorcycle) with conventional cleaning products such as chemical compositions or solvents; however, the earth does not come out in its entirety, remaining as a yellow stain and as time passes, this accumulates and gives rise to scale and later to rust. This happens in all types of vehicles.

In the state of the art, patent CN108085166 discloses an acidic ceramic cleaning agent especially used for cleaning precision ceramic sleeves and its preparation method. The cleaning agent is prepared from raw materials in mass percent as follows: 10% phosphoric acid, 6% hydrofluoric acid, 3% citric acid, 18% diethylene glycol, 10% monobutyl ether, 3 % sodium tripolyphosphate, 3% dodecylbenzene sulfonic acid, 3% coconut fatty acid diethanolamide, 1% TX-10 phosphate, 1.2% a powerful wetting agent, 0.1% a bleaching agent fluorescent and the rest water. Among the disadvantages i That this product presents are found that it contains solvents such as monobutyl ether and phosphoric acid. These inputs are not good strippers for engines, rings; solvents act as hydrocarbon degreasers and have an effect that makes rubber hoses dry out; and they are not specific strippers for cleaning engines, rings and plastics and accessories.

On the other hand, in document WO2019002789, a chemical cleaning composition is described to dissolve an amorphous surface layer composed of metals or semiconductor materials in their oxidized form to selectively remove it from layers of other layers. This cleaning chemical composition adapted to remove from a substrate a passivation layer that comprises etching residues resulting from the chemical attack of said substrate, is characterized mainly because it comprises: a weak acid, such as acetic acid, between 20% to 95% by weight, preferably between 50% to 80% by weight, relative to the weight of the chemical composition, a strong non-oxidizing acid, such as methanesulfonic acid, between 5% to 50% by weight, preferably between 15% to 50% by weight, in relation to the weight of the chemical composition, hydrofluoric acid, with a content between 0.2% to 2% by weight with respect to the weight of the chemical composition, water, with a content between 2% and 20% in weight relative to the weight of the chemical composition. Among the disadvantages of this product are that, due to the chemical composition of this compound that is used to eliminate a passivation layer from a substrate, it is very weak to be able to clean engines in which due to the fever it remains very impregnated and is very difficult to clean with this product; and its pH has to be raised with another procedure in order to be able to strip quickly.

Products that are currently used to clean vehicle bodies, including engines and internal parts, have the disadvantage of causing dryness and cracks in the hoses (such as for the gasoline pass, covering the electrical cables of the vehicle), leaving stains on the surface of the vehicle's plastic accessories, they only act as degreasers and have no effect on scale and oxides. DESCRIPTION OF THE INVENTION

The present invention describes a composition to clean the bodywork, rims, engines and accessories of a vehicle, as well as the damage and scale that forms in said parts without damaging the original paint, which comprises a basic active part and a complementary part according to with the use that is given to it.

The active part of the composition to clean vehicle bodies, rims, engines and accessories, without damaging the paint, comprises the following inputs:

Linear Alkylbenzene Sulfonic Acid (Linear Sulfonic Acid). This input is acquired at 96%, it is an anionic surfactant that, due to its acidic characteristics, makes it have a good affinity with hydrofluoric acid; its property as a degreaser gives it a good cleaning to the vehicle.

Hydrofluoric acid. This input is purchased at 73%, it is the main ingredient to remove scale and oxides, which due to its great affinity with aluminum and aluminum-derived compounds make it have a good result, especially in cleaning engines and rings of this material. and its alloys.

To enhance the composition and clean the scale without damaging the paint of the vehicle body, it comprises the following inputs, the composition is reformulated by adding to the active part, a complementary part whose inputs are indicated below:

THE TENSOACTIVE, is used for all kinds of detergents, as well as shampoo, liquid soaps, etc.

Among the surfactants, you can choose from the group of anionic surfactants: sodium lauryl sulfate, sodium dodecyl sulfate or sodium dodecyl benzene sulfonate, sodium alkyl benzene sulfonate, sodium alkyl sulfonate, sodium alpha olefin sulfonate, sodium alkyl sulfate , sodium alkyl ether sulfate, sodium monoglyceride sulfate, sodium nonylphenylether sulfate, sodium alkyl phosphate, oleylether phosphoric acid, sodium alkyl ether phosphate, sodium alkyl ether sulfosuccinate, disodium alkylmonoethanolamides sulfosuccinate, sodium dialkylsulfosuccinate, sodium nacetyl sulfate, sodium lauryl sulfate sodium lauryl sarcocinate, sodium alkylamidopolypeptidate.

Also, one can choose from the group of cationic surfactants such as: cetyl ammonium bromide, alkyl dimethylbenzylammonium chloride, cetyl triethyl ammonium chloride. Also, an amphoteric surfactant such as alkyl dimethyl betaine can be chosen.

Lastly, a non-ionic surfactant such as ethoxylated nonyl phenol or ethoxylated nonanol can also be chosen.

In a preferred embodiment, the chosen surfactant is sodium lauryl sulfate. THE MOISTURIZER is used in the cosmetic industry and is responsible for giving shine to the surface where it is cleaned. The humectant is a compound chosen from the group of diol alcohols, in a preferred embodiment it is propylene glycol. THE pH REGULATOR is widely used in cleaning products. The pH regulator is a compound chosen from the group of amines, monoethanolamine, diethanolamine, triethanolamine. In a preferred embodiment, Triethanolamine is used, which acts as a pH regulator and, being a weak base, also acts as a corrosion inhibitor.

POLAR SOLVENT is a compound chosen from the group of protic polar solvents, such as water (H-O-H), ethanol (CH3-CH2-OH) and acetic acid (CH3-C (= 0) 0H).

In a preferred embodiment, the polar solvent used is ethanol because it acts as a solvent in either an acidic or an alkaline medium.

THE THICKENER is the carboxy methyl cellulose compound (CMC), which is the most common used to increase the viscosity of a liquid and because it is food grade, this makes the product more for domestic use.

The procedure of the active part and the complementary part of the composition to clean bodywork, rims, engines and accessories of a vehicle, without damaging the paint, follows the following stages: In this operation, there are not many parameters to take into account because this The process is a simple mixture that occurs at a temperature between 25 ° C and 30 ° C, and the components to make the complementary part are food grade. Obtain the active part according to the previous procedure and it must be mixed with the complementary part obtained in another container, there is no exact time to mix both, since the mixture can be done at any time.

1. Take into account that the mixture has to be made in two separate containers.

2. In the first container, the surfactant is diluted in water until it is completely dissolved, the time to dilute it in water varies depending on how fast it is squeezed and the amount to be dissolved in water. Regarding the Temperature, it does not change because it works, at the temperature T = 29 ^Q C. 3. Once the surfactant has dissolved, add the humectant and stir slowly until it is completely mixed, T = 29 ^Q C.

4. To the previous mixture obtained, add the polar solvent and stir slowly until completely mixed, T = 29 ^Q C.

5. The pH regulator must be added to the previous mixture obtained and stir slowly until completely mixed.

6. In the second container, the fast-acting thickener is dissolved in water, this means that it does not form lumps and we do not have to heat the water, dissolve until it has the texture of a gel, T = 29 ^Q C.

7. Mix the contents of the two containers and move slowly until the mixture is homogeneous, the order of the way of mixing the containers does not matter since it gives the same result T = 29 ^Q C.

In the process of elaboration of the complementary mixture, the parameters are not taken into account because there are no violent reactions and neither highly acidic or alkaline inputs or an increase in temperature.

Each of these inputs act as stripping agents, hydrofluoric acid is an acid stripper and sulfonic acid is a surfactant stripper.

The mixture of both dilute hydrofluoric acid and sulfonic acid have very good affinity and if they are mixed, they still work as strippers.

The composition to clean vehicle bodies, rims, engines and accessories, without damaging the paint, cleans scale, especially on aluminum engines, leaving surfaces clean and shiny. Its concentrated formula of acidic compounds with adjuvant and surfactants, the acidic pH allows to remove the scale without damaging the cables, hoses, plastic accessories and rubber.

Clean the plastic casing of motorcycles without damaging it.

It cleans the damaged bodywork of the vehicles without damaging the paint and for this the active part must be mixed with the complementary part to lower the pH and not damage the car paint, keep in mind that the bodywork must have the original paint. It is also a product that cleans the glass and windshields of vehicles when they are completely invaded by fungi due to the humidity in the city.

In the second container dissolve the fast acting carboxy methyl cellulose this means that it does not form lumps and we do not have to heat the water, dissolve until it has the texture of a gel T = 29 ^Q C.

7. Mix the two containers and move slowly until the mixture is homogeneous, the order of the way of mixing the containers does not matter since it gives us the same result T = 29 ^Q C

Linear alkylbenzene sulfonic is purchased at 96%.

In the process of elaboration of the complementary mixture, the parameters are not taken into account because there are no violent reactions and no very acidic or alkaline inputs or increase in temperature.

The composition to clean rims, engines and accessories of a vehicle, without damaging the paint, is used to clean the external surface of aluminum engines, rims or any accessory made of this material. For its application it is recommended to dilute it in water in proportions of 1 to 4 (for 1 liter of the product it must be diluted with 4 liters of water), after applying the product wait approximately 20 seconds, if it is a motorcycle engine and then rub with brush. But if it is for older vehicles, wait 1 to 2 minutes that will depend on the degree of dirt that the engine has. To clean the paint of the vehicle body, it is necessary to mix the active part with the complementary part so that it does not damage the paint and can have an excellent result, but it has good results if the paint of the body to be washed is original paint .

The advantage of mixing with the complementary part is to save time because washing with this mixture has a good result, since, apart from the fact that the complementary part does not damage the paint, it can clean the oils, greases or particles that can hardly cleaned with other products, at the same time the effect it has on cleaning the paint damage.

There are two ways to clean the body without damaging the paint. The active composition dilute it in water and the proportion is 1 to 8, exclusively wash the bodywork manually and the washing is in parts or in a segmented way. It is recommended to wash in parts because due to its pH = 3 it is necessary to wash quickly in approximately 5 seconds and it must be rubbed with a cloth and then rinsed with plenty of water.

The active composition dilute it with the complementary part and the proportion is from 1 to 8, it can be used with equipment (air guns, shampoos) it does not damage the body with this form of washing because the pH increases from 1 to 6 and this makes that it is possible to clean not only the body but all parts of the vehicle without exception.

That is why the active part is extremely important because it has many applications and it all depends on what you want to clean.
