Description

The present invention is a self-polishing and antistatic coating composition suitable for the care of skins and imitations, wood or metal surfaces coated with polymer-based varnish or paint, and plastic floors.

Compositions containing various wax emulsions and polymers are known to be used for the above purposes.

The requirement for these compositions is that they be applied to the surface to be treated to form a high-gloss, high-gloss coating which is also water repellent.

Such a composition is described in U.S. Patent No. 3,912,679. The composition comprises wax, synthetic resin, plasticizer, emulsifier, fluorine-containing surfactant and silicone compound in an aqueous medium. The composition on the skin and imitation leather forms a shiny, elastic film that allows water vapor to pass, so when applied to shoes, it does not prevent footwear from breathing.

U.S. Pat. No. 4,265,663 uses a similar composition for this purpose. The composition disclosed herein comprises, besides wax, a dimethylsiloxane polymer. U.S. Patent No. 3,960,575 discloses a skin care composition consisting of wax, polydimethylsiloxane, silicone amino-function, surfactant and water.

German Patent Publication No. 2,435,135 proposes for this purpose a composition comprising a wax, polydimethylsiloxane, an amino-functional siloxane compound in the form of a dispersion in gasoline.

German Patent No. 2,537,700 discloses an aqueous composition consisting of an aqueous dispersion of a polyacrylate homo- or copolymer, a wax emulsion and additives as a polishing or care agent.

U.S. Patent No. 3,931,079 discloses a composition comprising an aqueous wax emulsion, polydimethylsiloxane, and surfactants.

A common disadvantage of the above-described compositions is that they cannot meet the combined requirement of high surface brightness and antistatic effect, or can only be partially fulfilled in an individual case determined by the purpose of use.

An object of the present invention to overcome the disadvantages of the above-described compositions is to provide a composition which has an increased surface luminosity compared to the known compositions, and which makes the coated surface less antistatic and thus more widespread than the prior art.

The present invention is based on the discovery that an amino-containing polydimethylsiloxane of formula V wherein m is 3-6, n is 5-15, Rx and R2 are hydrogen is 1: 0, By reacting it in a 5 to 1 molar ratio, it produces a material which is well suited as an additive for self-polishing lotions with a moss surface gloss, antistatic effect, and a wide range of uses.

The antistatic agent which enhances the surface luster is characterized by the general formula (I). In the formula, m, n are as defined above, R 1 is H, R 5 is (II), or (III) or (IV).

In addition to the specific siloxane additive, the composition of the present invention comprises a wax emulsion, optionally an aqueous dispersion of styrene / acrylate copolymers and an aqueous dispersion of acrylate resin, surfactants, plasticizer, optionally petroleum, or other solvent, and poly (dimethyl) silane, Contains known filler, corrosion inhibitor additive, bacterial ericide.

The composition of the invention is formulated in vials or in aerosol form.

The composition of the invention is applied in a thin layer to the surface to be treated. After evaporation of the solvent, a good adhesive coating is obtained, which is high-gloss and prevents the electrically charged surface of the treated surface.

As a result, the treated surface becomes conductive in the electrostatic sense 10 ~ Ohm-MSz 16040 (1-73), thereby avoiding the possibility of dust-brain impurities being deposited on the surface due to electrical charge.
