Description

The present invention relates to corrective compositions for eliminating defects that occur on rubber, plastic, wooden surfaces, as well as for restoring the base layer of car bodies without damaging the surface.

From the current level of technology there is known a composition containing a substance of a wax structure, a pigment, and a liquid silicone polymer material in the following proportions: carnauba wax 5%; montan wax 35%; paraffin 35%; pigment 13%; liquid silicone polymer material 12% [US patent US 5821291 A from 10/13/1998. Stick for filling, masking and sealing scratches in a painted substrate. IPC C08L 91/06; C09D 5/34. Application No. 829908 of March 26, 1997]. This composition has insufficient plasticity, which does not provide high-quality filling of deep scratches and chips, does not have high adhesion to the surface of the vehicle body, and also does not provide the desired anticorrosive effect of the drug. In addition, it uses expensive materials.

A known composition for a protective coating with polishing properties [RF patent RU 2031917 C1, publ. 03/27/1995. Composition for a protective coating with polishing properties. IPC C09D 191/06, C09D 5/08, C09D 183/04. Application: 5006231/05 of 10.23.1991] containing montan wax, petroleum paraffin, wool fat, stearic acid, polyethylsiloxane liquid, aqueous ammonia, white spray, water. The disadvantage of this composition is the impossibility of long-term storage of the composition, because its animal fat does not have a long shelf life.

Also known is the composition of crayons for protecting vehicle surfaces from atmospheric phenomena, which is also a means of car care, and is used, in particular, for sealing various surface defects of a vehicle [RF Patent RU 2008137704/04, publ. 07/20/10 g. Wax composition for restoration of vehicle surfaces. IPC C09D 191/06, C09D 183/04, C08L 91/06, C08L 93/04. Application: 2008137704/04, dated September 19, 2008]. They are obtained on the basis of compositions containing 30% carnauba wax, 40% ceresin, 10.8% pigment, 9% mica, 0.2% polymethylsiloxane, 10% abietic acid.

Closest to the claimed technical solution is [RF patent RU 2135538, publ. 08/27/1999, the composition of the pencil for applying colorful coatings. IPC C09D 13/00. Application: 2135538 dated 10.29.1997], which provides the composition of crayons for painting various surfaces: paper, cardboard, canvas, rubber, wood, glass, etc., and can be used for artistic purposes. The composition is obtained on the basis of compositions comprising 10 ÷ 90% solid binder (technical stearin, paraffin, olein, ceresin, brown coal or extraction wax, anti-aging agent or a mixture thereof), 0.1 ÷ 30% oil, 0.01 ÷ 40% metal compounds, pigment and various fillers (mertallite, bentonin, aluminum or bronze powder).

The technical result of the claimed invention is the creation of a wax composition:

- easy to use;

- having a long shelf life and storage;

- providing water-repellent properties;

- with high ductility and adhesion.

This technical result is achieved due to the fact that the corrective composition for eliminating defects includes CCD petrolatum, filler (mica), pigment (carbon black P-234) and additionally contains a plasticizer (liquid paraffin).

Petrolatum with a melting point of at least 70 ° C is used as the basis for the corrective composition.

The shelf life of the corrective composition depends on the shelf life of the components and is usually 2–3 years. The expiration dates of the various components are shown in table 1.

After applying the product to the surface, the basis of the corrective composition (CCD petrolatum) creates a protective layer that repels moisture and dirt, thereby providing water-repellent properties (an example is shown in figure 1).

The filler in the composition ensures uniform application of the product on the treated surface, as well as the required coating quality (gloss or dullness). Mica (phlogotype or muscovite) was used as a filler. An example of a surface treated with a corrective composition is presented in figure 2.

To give the composition a color corresponding to the color of the restored surface, pigments are added to it. To mask tire scratches in the tire industry, a corrective composition of black color is required, therefore P-234 carbon black is used as a pigment.

The plasticizer allows you to obtain the desired ductility, softness of the composition and provides the required quality of application to the surface. As the plasticizer content increases, the plasticity, softness and adhesion of the sample increase. The figure 3 presents samples with the content of plasticizer.

The advantage of the proposed technical solution is the homogeneity of the corrective composition in its structure, obtaining a uniformly colored, black, wax-like product with a melting point of 45 ÷ 65 ° C. The formulation of the invention are shown in table 2.

The specificity of the formulation of the developed corrective composition ensures its easy application to the treated surface, good masking of defects. After exposure to low temperature (dry ice), the appearance of the surface treated with the corrective composition will not change, which is expressed in the absence of color change, cracking, chipping and shedding (the test sample is shown in fragment 4).

The technology for producing the wax composition is as follows. In the mixer with a heated jacket load all the components of the composition. Cooking is carried out at a temperature of 90 ° C with vigorous stirring until the base is completely melted and a homogeneous composition is formed.

Ready-made corrective compounds are packaged in packages that protect products from the effects of precipitation and mechanical damage.

The use of the inventive corrective composition is as follows.

The wax corrector is applied with gentle movements, first across, and then along the scratch, paying attention to the smallest damage. Once the damaged area is hidden, you can begin to polish the treated surface with a dry cloth, which will eliminate the excess of corrective composition.
