Summary of the invention
The object of the present invention is to provide a kind of new automobile curing fluid capable, can reach beyond thought cleaning effect after the use, not only can keep body of a motor car clean bright, and be difficult for the absorption dust,
A kind of nursing liquid for automobile of the present invention is divided into mother liquor and working fluid, and its mother liquor comprises following component by percentage: tween 1~60%, and polyacrylamide 0.01~50%, all the other are water; With 100 to 1000 times of described mother liquor dilute with waters as working fluid.
Preferably, described polyacrylamide is that molecular weight is at 7,500,000 to 2,000 ten thousand daltonian polyacrylamides.
Tween (Tween-20, Tween-40, Tween-80) is a kind of nonionic surface active agent, derives from natural product, does not contain nonnitrogenous, the phosphorus compound of big naphthenic hydrocarbon, and readily biodegradable does not pollute environment.Have multiple performance, as absorption, wetting, infiltration, emulsification, dispersion, bubble, solubilising etc., its performance synthesis determines the soil removability that it is powerful.The present invention as one of component of nursing liquid for automobile, can reach the car body dirt is stable with surfactant micelle, dispersive effect with tween.
Determining of tween concentration: water phase surfactant mixture character changes with the variation of concentration, many character at critical 0~5% internal surfactants aqueous solution, noticeable change all takes place as surface tension, molar conductance, turbidity, osmotic pressure and soil removability, surpass this scope and work as concentration, along with the increase SOLUTION PROPERTIES of surfactant concentration no longer includes noticeable change, therefore surfactant concentrations should remain on a little higher than threshold concentration and could neither waste and can give full play to its soil-removing action in washings.As shown in Figure 1.Consider that reducing aqueous solution surface tension is purpose, in nursing liquid for automobile of the present invention, the work final concentration protection domain of tween is: 0.01-0.6%, so its mother liquid concentration is 1-60%.
Polyacrylamide (PAM) is a high molecular weight water soluble polymer, is insoluble to most of organic solvents, and performances such as good flocculence, thickening property are arranged.PAM (polyacrylamide) itself is avirulent to Mammals, hydrobiont and field-crop, and is atomic to environmental influence, do not have the problem of burning and blast aspect.
The structurally the most basic characteristics of PAM are: 1, molecular chain has the volatility of kindliness and molecular conformation.As the PAM of molecular weight 7,100,000, the length-to-diameter ratio after its molecular chain stretches is up to 10
5, be equivalent to the filament of diameter 1mm, long 100m.Can imagine that the flexible molecule chain of big L/D ratio is very easily to curl like this, also very easily tangles between the molecular chain.2, have identical side group-amide group on the molecular chain, and amide group has high polarity, easily forms the long-chain mortise that conjugated link(age) can make entanglement, conjugated link(age) bonded macromolecular material electronics can transmit between singly-bound and two key, has the characteristic of conduction.The conduction of metal is done relay just as the conduction of electronics conducting polymer doing marathon race just as electronics and is run between conjugated Dan Shuanjian, conjugated polymer can be used for eliminating static, eliminates the absorption that the electrostatic lacquer painting can reduce dust.When the rheological of PAM makes liquid-flow and the resistance of tube wall reduce.These constructional features are given PAM extremely valuable application performance.Make the PAM aqueous solution have good rheology modulability as submissive long-chain; Amide group very easily with contain-material (car lacquer lacquer painting) of OH group forms hydrogen bond, produces very strong adsorption.What PAM solution precipitating after drying obtained is a kind of transparent hard glassy polymers, PAM is trapped in because in the depression that air erosion lacquer painting causes, because the chemisorption of hydrogen bond and intermolecular reactive force and physical adsorption make the firm depression that is filled in lacquer painting of sedimentary PAM produce clean bright mirror effect in the washing lotion because the molecular sieve effect makes in the car body cleaning process.
Contain tween and polyacrylamide in the nursing liquid for automobile of the present invention, its principle of work is:
The dirt of car body mainly exists with following form.1, the dirt of piling up in the car body surface sedimentation by action of gravity merely.The external dirt that this form exists, very weak at the sticking power of body surface, be easier to remove from body surface.2, the dirt particle leans on electrostatic attraction attached to body surface.The body surface of many poorly conductives tends to be with electric charge in air, and charged dirt particle will be adsorbed onto car body surface by electrostatic attraction.When this class material was immersed in the water, because water has very big specific inductivity that the electrostatic attraction of dirt and car body surface is greatly weakened, this moment, this class dirt just dissociated from the surface easily.3, atmosphere dust and dirt.In air, there is the very little dust granules of diameter usually, greatly increased, be exposed to the easier formation dirt of body surface under such atmospheric condition by the dust amount that contains in the atmosphere of industrial pollution.Dust and the bonding force of car body are decided by the area that grit contacts with car body and the surface energy (surfactivity) of grit.Because the composition more complicated of dust and dirt is difficult to find the suitable solvent that can dissolve dust and dirt fully.
Consider the factors such as aggressiveness to car body surface, we have selected the highest nonionic surface active agent Tween solution of HLB value to make clean-out system.In cleaning process, utilize wetting, the osmosis of tween to remove dust and dirt.When washing composition with after dust and dirt and car body surface contact, at first reduce the surface energy of dust and dirt, in the absorption interface that dust and dirt contacts with car body, permeate then, eliminate the bonding force between dust and dirt and the car body.Car body surface also adsorbs the surfactant molecule that one deck aligns simultaneously, so dirt can not deposit on the lacquer painting again.Again in conjunction with dash, mechanical external force effect such as spray makes dust and dirt break away from car body surface and is eliminated.Simultaneously, tween is difficult for absorption dust for the nonionic surface active agent neutral makes the car body after the cleaning.The effect of polyacrylamide (PAM) is particularly important, PAM is trapped in because in the depression that air erosion lacquer painting causes in the washing lotion because the molecular sieve effect makes in the car body cleaning process, sedimentary PAM does not have concavo-convex lacquer painting can produce clean bright mirror effect because the chemisorption of hydrogen bond and intermolecular reactive force and physical adsorption make the firm depression that is filled in lacquer painting of PAM.Therefore, clean automobile, can wash brighter and brighter, simultaneously, eliminate static and the effect that reduces relative static friction coefficient, the absorption of dust when objectively also having reduced running car because the inertia polymer of covering body has with nursing liquid for automobile of the present invention.
Described mother liquor also comprises following component by percentage: mineral compound washing assistant 0~5%.
Described mineral compound washing assistant is selected from one or more combination of tripoly phosphate sodium STPP, water glass, yellow soda ash, sodium sulfate.
Described mother liquor also comprises following component by percentage: organic compound washing assistant 0~5%.
Described organic compound washing assistant is selected from nitrilotriacetic acid salt, Trisodium Citrate, polyacrylic one or more combination.
Between above-mentioned washing assistant and the surfactant molecule complex interactions takes place, the result makes washing effect than using the tensio-active agent fashion separately.
Preferably, described mother liquor also comprises following component by percentage: triton x-100 0~10%.
Triton x-100 (TritonX-100) is a kind of nonionic surface active agent, can strengthen the effect of tween, also can be used as sterilant, removes the insect corpse of car body surface.
Preferably, described mother liquor also comprises following component by percentage: sodium azide 0~0.02%.
The effect of sodium azide is anticorrosion.
Preferably, described mother liquor also comprises following component by percentage: Virahol 0~50%.
The effect of aqueous isopropanol is to guarantee that the concentrated solution of selling is stable.
Compare with existing like product, nursing liquid for automobile of the present invention has the following advantages:
(1) dispose spissated mother liquor earlier, its raw material sources are convenient, and preparation is simple, is easy to preserve, and redilution was working fluid for 100 to 1000 times before reality was used, and had reduced use cost.
(2) easy to use, the carwash effect is very good, washes brighter and brighter, has solved the problem of carwash difficulty preferably.The car owner spends more than ten minute cleaning wiping vehicle body that the love car is taken on an entirely new look, and without any side effects again to lacquer painting, life-time service can play good maintenance effect to automobile.
(3) with after the cleaning of this nursing liquid for automobile, when running car, can reduce the absorption of dust.
(4) behind the carwash, can form the protective membrane of one deck light, make the vehicle cleaning blast, lacquer painting is had prolongs life effects such as (preventing that lacquer painting from wearing out, coming off) at lacquer painting.
(5) working fluid environmentally safe.
