Description

Concentrated multifunctional cleaning and maintaining car washing liquid
Technical Field
The invention relates to a car washing liquid, in particular to a concentrated multifunctional cleaning and maintaining car washing liquid
Background
The automobile as a travel tool can not naturally avoid 'head throwing and surface exposure', and the automobile body is difficult to be prevented from being eroded by dirt, ultraviolet rays and the like due to the influence of external environments such as driving road conditions or parking positions and gradually loses the bright appearance. Whether the automobile body is clean or not is not only related to the problem of 'surface', but also influences the service life of the automobile. Therefore, the clean maintenance of the vehicle body is particularly important.
The traditional solution is to remove the dirt of the car body by washing the car, and in order to further enhance the effect, the constructions such as waxing, film coating, glaze sealing, crystal plating and the like are often carried out, so that the anti-pollution capability of the car body is enhanced, and the aging speed of the car body is delayed.
The car washing, as the name implies, is to use the detergent to clean the car body and restore the original clean appearance of the car body;
waxing, namely uniformly coating car wax on a car body as a traditional project of car cosmetology so as to form a waterproof and high-gloss protective layer, wherein the effective time is about one month;
coating, namely uniformly coating a glazing material with high adsorption force such as resin with high gloss or emulsion thereof on a vehicle body to form a glazing protective layer, wherein the effective time is about three months;
glazing, namely, a glazing curing substance is strongly permeated into the surface of the vehicle paint by using soft materials such as wool or sponge and the like through high-speed vibration and friction of a vibration polishing machine, and the effective time is about half a year;
and crystal plating, namely applying a layer of crystallizable substance with certain glossiness, hardness and hydrophobic ability on the paint surface, and firmly fixing the crystallizable substance on the surface of the vehicle paint through chemical reaction, wherein the effective time is more than one year.
The protective capacities of waxing, glazing, coating and crystal plating are sequentially increased, so that the construction difficulty is also sequentially increased, the operation process is complicated, and time and labor are wasted. Part of the operations need to be carried out in a dust-free workshop, polishing and other operations need to be carried out according to different vehicle conditions, most individual users are difficult to independently complete the operations, and professional construction of a steam repair shop is needed. The current time concept of people is increasingly strengthened, the time cost and the labor cost are also continuously improved, and the time concept is obviously unfavorable for users.
In addition, the four maintenance methods have strong hydrophobic effect, dense, hemp and round and rolling water drops are easily formed on the paint surface after the paint surface is soaked with water or the rain day passes, if the water drops are not discharged in time, the water drops directly stay on the paint surface until the water drops are dried, the residual calcium and magnesium salts after the water drops are dried can be firmly adsorbed on the paint surface to form 'watermarks' which are difficult to remove, and the appearance of the paint surface is seriously influenced.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a concentrated multifunctional cleaning and maintenance vehicle washing liquid.
In order to achieve the purpose, the invention adopts the technical scheme that: a concentrated multifunctional cleaning and maintaining car washing liquid comprises the following components in parts by weight: 2-10 parts of amino modified polydimethylsiloxane, 15-20 parts of surfactant and 73-85 parts of water;
wherein the structural general formula of the amino modified polydimethylsiloxane is RnSi(NHaR＇b)4-nWherein: r, R' are identical or different monovalent organic groups; n is an integer between 1 and 3; a and b are integers between 0 and 2, and a + b is 2;
the amino modified polydimethylsiloxane is a mixture of at least two amino modified polydimethylsiloxanes with different viscosities.
The concentrated multifunctional cleaning and maintenance vehicle washing liquid is based on deionized water, the amino modified polydimethylsiloxane with hydrophobic effect is uniformly dispersed in a water carrier through a surfactant and is neutralized with organic acid to be converted into a cationic form, the paint surface of a vehicle body is used as a material rich in hydroxyl, the affinity of the protonated amino modified polydimethylsiloxane with the vehicle body is enhanced, the rupture of a water film is improved, the flowing of water is promoted, and the conditioning effect and the glossiness are improved.
The concentrated multifunctional cleaning and maintenance vehicle washing liquid can quickly remove various dirt on a vehicle body without influencing the strength and the wear-resisting property of the original paint surface, and the treated paint surface has some characteristics of amino modified polydimethylsiloxane due to the adsorption of protonated amino modified polydimethylsiloxane, such as high thermal stability, hydrophobicity, high glossiness and the like.
In terms of effective time, the car washing liquid developed by the invention has a polishing and hydrophobic effect for about two weeks, is not lasting, and is far shorter than the time for waxing, glazing, coating and crystal plating, but has the greatest advantages of repeatability and sustainability.
At present, most of users wash the car between one week and two weeks, and because the polishing and hydrophobic effects of the car washing liquid developed by the invention are attached to the car washing, the polishing and hydrophobic effects of the paint surface can be endowed and sustained by using the concentrated multifunctional cleaning and maintenance car washing liquid to carry out common car washing operation, so that the polishing and hydrophobic effects of the paint surface can be endowed and sustained by washing the car once and again, the operations of waxing, glaze sealing, film coating, crystal plating and the like are omitted, and the time, the labor and the material resources are saved.

As a preferable embodiment of the concentrated multifunctional cleaning and maintenance vehicle washing liquid, the amino-modified polydimethylsiloxane is a mixture of at least one of amino-modified polydimethylsiloxane A and at least one of amino-modified polydimethylsiloxane B; the viscosity of the amino modified polydimethylsiloxane A is 1-500 cps; the viscosity of the amino modified polydimethylsiloxane B is 1000-10000 cps.
Regarding the selection of the amino-modified polydimethylsiloxane, the inventors found the following rule in the research process:
the higher the viscosity of the amino modified polydimethylsiloxane is, the better the glazing performance and the poorer the anti-fouling performance of the product are;
the lower the viscosity of the amino modified polydimethylsiloxane is, the poorer the glazing performance of the product is and the better the anti-fouling performance is;
thirdly, the water film breaking speed is related to the content of the amino modified polydimethylsiloxane, the larger the using amount of the amino modified polydimethylsiloxane is, the faster the water film breaking is, but the water film breaking speed tends to be stable after a certain amount of the amino modified polydimethylsiloxane is reached.
The viscosity of the amino modified polydimethylsiloxane A is 1-500 cps, the viscosity of the amino modified polydimethylsiloxane in the viscosity range is small, the antifouling performance is relatively good, the waterproofness is good, but the gloss is poor; the viscosity of the amino modified polydimethylsiloxane B is 1000-10000 cps, and the amino modified polydimethylsiloxane in the viscosity range has high viscosity, relatively high glossiness, good waterproofness and poor antifouling property. Therefore, in order to obtain a product with better effect, the invention mixes the low-viscosity amino modified polydimethylsiloxane A and the high-viscosity amino modified polydimethylsiloxane B for use, thereby obtaining the product with good polishing performance and good anti-fouling performance.
