Description
The present invention relates to a kind of spray-type cleaning and polishing soft wax, in particular for the composition of automobile clean light soft wax.
The car surface paint film, owing to often be subjected to the erosion of various compositions such as the mud of waste gas, rural area ridge of the oiliness dust of silt, vehicle on natural rainwater, dust, road surface and factory chimney or acid rain, be easy to cause the pollution and the damage of car surface paint film, if the automobile of this pollution only is the flushing of simple water or adds the water flushing with mild detergent and dry, will the paint film of automobile be injured and wear out in the course of time.If on the automobile paint film after the cleaning, be coated with the protection wax of getting on the car, then can make its light and cleaning.Bibliographical information about automobile protection wax is a lot; for example: US5110891 (1991), JP5148454, CN96116220, CN96123169, CN90109026 report; the fusing point of the wax of using with the automobile polish of known available is all lower; the silicone resin of adding usefulness is the organic silicone oil of liquid; boiling point is higher not volatile; very easy suction ash, especially when the roof of automobile in summer after burning sun tans by the sun, the vehicle body temperature can reach 80-90 ℃.Though these raw material consumptions seldom, owing to reach its fusing point already on the automobile paint film, viscous liquid is easy to cling airborne dust.Therefore, after cleaning automobile, can not form the automobile paint film supercoat of dystectic antidusting dust of light, the very fast disappearance of the light of car surface in the course of time at car surface.For this reason, the present invention is improved at this shortcoming exactly.
The purpose of this invention is to provide a kind of sprayed automobile cleaning and brightening soft wax composition that contains special macromolecule resin, it is the composition that contains four kinds of different macromolecule resins and a kind of quaternary surfactant and solvent, said composition can improve the automobile clean brightness effect, can strengthen, increase gorgeous automobile paint film effect and can improve the antidusting of automobile paint film, antifouling, water-sprinkling effect.
Sprayed automobile cleaning and brightening soft wax composition of the present invention is to include polyvinyl resin, the composition of the quaternary surfactant of the silicone resin of super large molecule and the silicone resin of extra small molecule, organic fluorinated silicone resin and anti-negative charge and the petroleum solvent of two kinds of different boiling, the proportioning of its component and content is as follows:
1. polyvinyl resin, molecular weight is 5,000-10,000, in composition, account for 1-15 weight %;
2. super large molecule silicone resin, molecular weight is 1,000,000-1,500,000, in composition, account for 0.1-2 weight %;
3. extra small molecule silicone resin, molecular weight are 200-1,000, in composition, account for 0.2-10 weight %;
4. organic fluorinated silicone resin, molecular weight is 150-2,000, in composition, account for 0.5-5 weight %;
5. quaternary surfactant accounts for 0.05-1 weight % in composition;
6. petroleum solvent has two kinds: a kind of is boiling point 130-200 ℃ solvent oil, and another kind is boiling point 180-300 ℃ a kerosene, and both part by weight are 1: 2-4, both account for 70-95 weight % altogether in composition.
The structural formula of the polyvinyl resin that uses among the present invention is:
T=200-500 in the formula
Molecular weight is 5,000-10,000., because its molecular weight is very big, corresponding fusing point is higher.Film even also can form the fixed solid in the summer of broiling sun when filming, be difficult for sticking grey dust suction in the formation of the surface of automobile paint film.Polyvinyl resin accounts for 1-15 weight % in the present composition.
