The principle of such scheme institute foundation is as follows:

1. decontamination and microemulsion:

The soil-removing action of cream for dry cleaning and finishing surface of leather, at first be high mixture ratio and the temperature control that utilizes the kinds of surface promoting agent, and make it form certain density micellar solution (and surface tension, solubilising, decontamination, emulsification, the osmotic effect of used kinds of surface activator solution are closely related in the definite and preparation of this concentration, temperature) greater than micelle-forming concentration CMC value back, the micellar solution concentration that this product is determined not only can be dissolved dirt, the grease on the corium goods, and subsequent reactions is also had good katalysis.

Known to thousands of time experimental observations,, can make this product become microemulsion from micellar solution if in the dense micellar solution of this product, add grease, wax and the auxiliary (playing solubilization) of some amount and control proper temperature.

But the 2. formation of respiratory protective membrane:

Selected SF909 silicone oil and SF956 phenyl silicone oil in this product preparation; because the spread of silicone film is very capable; make leatherware can obtain having high-gloss finish and uniform top coat rapidly; and make the loose part of surface be absorbed with organosilicon polymer morely; and closely partially absorb less; dwindle appearance poor distance tight and loose part, formed " but respiratory protective membrane " and make coating effect both reach cleaning, light, reached sanitation performance ventilative, permeability to water vapour again.

Now that two kinds of silicone raw materials effect division in this product is as follows:

SF-909 silicone oil: it has good water-solubility and excellent surface activity, be one of the important auxiliary of this product and emulsifying agent, by the surface tension of reduction liquid, thereby good wettability and emulsifying property are arranged in this product, also have static resistance, flexible smooth and ventilation property.

The SF-956 phenyl silicone oil: color and luster auxiliary agent, hydrophobizing agent, lubricant as this product use, and it can give guard, hydrophobic, air-permeability, soft smooth property and the non-stick property of this product excellence, and is easier to mix with other oils.

3. emulsion stuffing and performance thereof:

In the present invention owing to utilized aniorfic surfactant (sodium laurylsulfate), nonionic surface active agent (Tween65) and SF-909 silicone oil excellent surface activity and emulsifying property, forming microemulsion (refining wax, brazil wax, paraffin oil, silicone oil) with multiple grease, wax is lubricated the quick sorption stuffing of hide fiber material, promoted grease to permeate to intracutaneous, improved leather pliability, improved the corium physical properties of articles, dissolve dirt effectively, reach decontamination, oil, soft, bright purpose.

From the test learn, adopt negatively charged ion, nonionic surface active agent simultaneously in this product after, surfactivity can increase greatly, helps emulsification.At this moment, surfactant soln easily forms micella, and has good wet performance.Helping this product fat liquor in dry-cleaning, covering with paint permeates to intracutaneous.

4. stablizer PVA:

Adopt high molecular polymer PVA can strengthen product stability in this product, make it in dry-cleaning, covering with paint, play the medium effect, easily form the small-particle (like the frosted shape) of rolling in the use by the rubbing of hand (or dried soft cloth), it both can evenly be coated on surface synergy with emulsion, dirt can be with down at any time again, be had concurrently dual-use function.

Positively effect of the present invention is as follows:

It has reached the dirt-removing functions of product fine scientifically by the formed micellar solution concentration of combination of controlled temperature, oil-water system, auxiliary and kinds of surface promoting agent; Simultaneously, micellar solution again solubilising the grease of volume, wax, form microemulsion, leatherware obtains stuffing, oils, soft, bright effect thereby make.
