Abstract

Sowing belongs to the surface industry product modifications. Currently used technologies surface treatments are based for manual surface sealing and subsequent by hand grinding the putty. This work is strenuous and time-consuming. Addressing these remedies. Its essence it is that for products where they are a smooth and glossy finish is required is sprayed on using a spray gun nitrocellulose putty a synthetic baking enamel; Yippee this mixture is diluted with acetone if necessary diluent. The result is a surface whose structure forms tiny drops putty which, after subsequent spraying visually equalizes the top color possible unevenness of the substrate and can be look like a leatherette surface or oranges.

Description

The present invention relates to a method of surface treatment of any article in which any unevenness is to be masked or where a smooth, shiny surface of the article is not desired, the surface being sprayed with small drops of nitrocellulose spray or repair mastic. sprayed with any paint.

The previously known and used technologies provide for the treatment of uneven and coarse surfaces by applying several layers of sealant to the surface by hand, which is dried after drying and a topcoat is applied to the surface. Also, the surfaces of some products are sprayed with a special paint that coagulates on drying to create a surface that resembles the surface of a leatherette. These technologies are very demanding in terms of labor and material consumption.

The above-mentioned drawbacks are solved by the surface treatment method according to the invention, wherein a spray of a nitrocellulose sealant which is mixed with a synthetic baking varnish in a volume ratio of 9: 1 to 8: 2 is applied to the product surface using a spray gun. The mixture of sealant and baking synthetic enamel adds a maximum of 15% by volume of acetone-based diluent based on 100% by volume of the mixture of sealant and enamel, and the supply air pressure to the spray gun is reduced to 300 to 100 kPa.

By using said surface treatment method, a surface structure is obtained which optically compensates for the unevenness of the product surface which would have to be cemented and grinded using conventional technologies. The texture of the surface resembles the surface of an artificial leather or orange.

The solution will significantly reduce labor and material wherever surface finishing of products is carried out.

Example

The nitrocellulose sealant is mixed in a 9: 1 volume ratio with a synthetic baking varnish and 10-15% by volume of acetone diluent based on 100% by volume of the sealant / enamel mixture is added. The mixture is thoroughly mixed, filled into a spray gun receptacle at which the air inlet pressure is reduced to 300 kPa and applied to the surface of the product to which the primer has been previously applied. On the surface, small drops of putty are formed, which after drying overcoat overcoat of the desired color and shade. Thus, the treated surface of the product appears optically like the surface of the leatherette.

Claims (1)

Spray coating process, characterized in that a 9: 1 to 8: 2 mixture of nitrocellulose mastic and synthetic enamel is applied to the product surface at a pressure of 300 to 100 kPa, further comprising 10 to 15% by volume of a diluent based on acetone, based on 100% of a mixture of mastic and enamel.
