Description

The invention relates to the field of decorative art, namely to surface treatment of products to obtain a special artistic effect - painting type Khokhloma.

A similar method for processing products is known, in which the surface is primed, putty, applied with a paint and varnish coating and inter-operative drying is carried out, followed by filling the metal layer in a vacuum chamber [1].

The disadvantage of this method is the increased complexity of the finish.

The aim of the invention is to reduce labor costs when finishing surfaces of complex profiles.

This is achieved by the fact that enamel with an opacity of 20–75 g / m ² and a film gloss of 58–70% is applied to the surface of the product as a paint and varnish coating.

Example 1. Products after grinding are primed with GF-020 primer prepared for application in accordance with GOST

4056-63. Primed products are dried at

PO — 120 ° С for 2 hours. Dried products are putty locally or completely putty PF-002 prepared for work in accordance with GOST 10277–76. Putty products are dried at 120 ° C for 2 hours, and then they are ground to the eighth grade of cleanliness. The polished surfaces of the products are covered with a black PF-223 enamel layer with a spreading rate of 20 g / m ² and a film gloss of 65–70%.

Enamel is prepared for operation in accordance with GOST 14923–69. The enamel coating is dried at 80-90 ° C for 4 hours. After drying, the enamel coated products are placed in a vacuum chamber and treated in a glow discharge field. A vacuum of 1'10 ~ ⁴ mmHg is created in the chamber. century, the melting current is 400-500 A, the evaporation current is 500-600 A. The products are processed for 15-20 minutes. After metallization, the surfaces of the products have a gloss degree of 85% according to the FB-2 gloss meter. The adhesion of the coating in accordance with GOST 5140-69 1 point. The metallized surfaces of the products are painted with paints and dried at 120 ° C for 3.5 hours. The dried products are coated with painted varnish M4-52. To do this, prepare passes3;

cryogenic solution of dyes yellow "3" and orange 2 "g". Dried products are coated with golden varnish in one of the known methods. For this, a saturated solution of the dyes yellow “3” (5 g) and orange 2 ”g” (1 g) in 100 g of ethyl alcohol in accordance with GOST 1799–71 or butyl alcohol in accordance with GOST 13935-67 is prepared at room temperature. A saturated solution of dyes is filtered through a filter and mixed with 1 l of urea-formaldehyde varnish brand M4-52 according to TU 6-10-764-74. The varnished products are dried at 120 ° C for 2 hours, and then a second coat of M4-52 varnish is applied without dye and dried for 2 hours at 120 ° C.

X to work in accordance with GOST 20481-75. After drying the last layer of enamel, the products are tilled in the same sequence and with the same materials as in example 1.

In addition to these enamel coatings, coatings from a number of other enamels have been tested. Good results were obtained when coating products with PF-223 enamels of black and Toluboi color, PF-133, Ml-12 sea waves, Ml-197 and Ml-1110, as well as enamels of the PF and Ml brands, which have good adhesion. Golden varnish deposited on the surface of the product, prepared according to the described method, gives the products the color of a uniform gilding and a rich color scheme.

prepared for applying paintwork in the sequence and with the modes described in example 1.

Prepared product surfaces are covered with three layers of PF-223 blue enamel with a spreading rate of 75 g / m ² and a film gloss of 58%. Each enamel layer is dried at 80 ° С for 3 hours. The enamel is prepared for operation in accordance with GOST 14923–69. After drying the last layer of enamel, the products are processed in the same sequence and with the same materials as in example 1.

Example 3. The surface of the product is prepared for applying the paintwork in the sequence and with the modes described in example 1.

Prepared surfaces of the product are covered with two layers of enamel ML-1110 color white night with a spreading rate of 50 g / m ² and a film gloss of 63%. Each layer of enamel is dried at 90-100 ° C for 1 h. The enamel is prepared
