FIELD: chemistry.

SUBSTANCE: invention relates to a wax composition for protecting surfaces of vehicles from atmospheric effects and is also a car care product, particularly for filling various defects on surfaces of vehicles. The composition contains a substance with a wax structure, a pigment and liquid silicon polymer material. The wax material used is carnauba wax or ceresin wax. The liquid polymer material used is polymethylsiloxane. The composition also contains mica and abietic acid.

EFFECT: obtaining a composition which has a long storage period and has high plasticity and adhesion, as well as water-repellent and anticorrosion properties.

 

The invention relates to the protection of vehicle surfaces from atmospheric conditions and at the same time is a means of car care products, in particular for sealing of various defects on the surface of the vehicle.

Known composition for protective coatings with polishing properties (patent RF №2031917)containing montanuy wax, paraffin oil, wool fat, stearic acid, polyethylsiloxane liquid, aqueous ammonia, white spirit, water. The disadvantage of this composition is the impossibility of long-term storage of the composition, because it contains fat of animal origin does not have a long shelf life.

Closest to the invention to the technical essence and the achieved result is a wax composition described in U.S. patent No. 5821291 Pencil for filling, masking and sealing scratches on the painted surface. The composition contains a substance wax patterns, pigment, and a liquid silicone polymer material in the following proportions: Carnauba wax 5%; montanuy wax 35%; paraffin 35%; pigment 13%; liquid silicone resin material 12%.

This composition has insufficient ductility, which does not provide high-quality filling deep scratches and chips, not has high adhesion with the surface of the body vehicles is a, and does not provide the desired anti-corrosive action of the drug. In addition, it uses expensive materials. The color scheme is no different variety, in no particular color with metallic luster (metallic).

The purpose of this invention is to provide a wax composition for sealing of various defects on the surface of the vehicle, easy to use, has a long shelf life, with waterproof and anti-corrosion properties, and compared with the prototype, higher plasticity and adhesion.

This is achieved by a composition comprising the substance of the wax patterns, a pigment and a liquid silicone polymer material, characterized in that the wax material is Carnauba wax and ceresin, as a liquid polymer material is used polymethylsiloxane, and, in addition, the composition of the added mica and abietic acid with the following ratio of components, wt.%:

Carnauba wax30-40%;
Ceresin30-40%;
Pigment1-11%;
Mica an 8.8-18.8 per cent;
Polymethylsiloxane0,2%;
Abietic acid10%;

Formulated with Carnauba wax is the hardest and sustainable natural waxes. Materials using Carnauba wax be thanks to it a more heat resistant and practicality. The excessive hardness of the wax is reduced in the inventive composition through the use of ceresin. Ceresin due to the crystalline structure, has good viscosity, therefore giving higher ductility of the final composition. The content of these substances it is in the range of 30-40% is optimal, since the content of Carnauba wax more than 40% of the final product becomes fragile that bad when filling defects on the restored surface. And when the content of Carnauba wax less than 30% of the final product becomes more fusible and soft - this reduces the quality of the reconstructed surface. When the content of ceresin less than 30% reduced adhesive properties and flexibility of the claimed composition, and when the content of ceresin more than 40% of the coating composition on the restored surface is difficult due to the soft structure of the composition. For imparting metallic luster and evenly the ti application of the composition to the surface of the vehicle in the composition is injected mica. As mica may be used Muscovite or any other type of mica produced for the paint industry. The lower limit of the quantitative composition of the mica was 8.8%. A smaller number will have no impact on the uniformity of application of the composition. The upper limit of the content in the composition of the mica is 18.8%. If the content of mica more than 18.8 per cent, will be violated adhesion of the final composition, it will become brittle. As a technological additive is introduced to the silicon - organic polymer - poly-methylsiloxane in the amount of 0.2%. He is known as a substance holocause structure and interoperability of the various ingredients, and is also used to impart water-repellent properties of the final composition. With fewer polymethylsiloxane would be reduced corrosion resistance of the inventive composition. To improve the adhesion of the composition to the surface of the vehicle is introduced abietic acid. The percentage of 10% is necessary and sufficient for the best "sticking" of the composition to the surface of the vehicle.

In order to give the composition a color that matches the color of the restored surface, adds a variety of pigments, both organic and inorganic or complex origin, and their mixtures. The properties of the composition from the use of various pigment is not changed. To make the composition, for example, black color is used, such a pigment like carbon black. The number of carbon black in the range from 1.0 to 11.0% depends on the saturation of the black color, and in combination with a white pigment (in the same range) color varies from light gray to black. Similarly, the use of other pigments or a combination of them will give another desired color.

The durability of the structure, its resistance to harmful environmental influences (humidity, low temperature, salt fog) is provided by the content of ceresin.

The technology of producing a wax composition is as follows.

In dispersant load all components, except pigments, melted them, and stirred at the temperature t=100°C for 2 hours. Then melt add pigments and continue stirring for another 20 minutes for a thorough distribution of all components in a homogeneous liquid mass. Then it is poured into a cylindrical metal mold, cooled and squeezed out of shape. The finished wax crayons wrapped in foil or put in special cases.

Using pencils of the proposed structure is as follows.

Select the pencil in a color that matches the color of the treated surface. Then, pressing the arandas, to apply the composition to the surface, producing movement pencil along scratched, or chipped to until all the scratch or chip is not filled by the composition of the pencil. The excess of the composition above the painted surface, you can wipe with a cloth.

Use in the inventive composition is less expensive and scarce components - Carnauba wax and ceresin - allows you to reduce the price of the wax composition, not reducing and improving those properties that are particularly important in the climatic conditions of the Russian Federation (the use of the composition at low temperatures, in conditions of salt fog).
