Abstract

FIELD: printing.

SUBSTANCE: invention relates to the field of decorative art, namely to the field of manufacturing decorative sculptures. The method of manufacturing sculptural-design articles comprises reinforcement layer by layer, drying, staining and varnishing, at that the volume article is moulded in sculptural plasticine, its surface is smeared with soap suds and poured with gypsum, after 10-20 minutes the gypsum is removed, 5-6 layers of vegetable oil are applied for 10-15 minutes, then the first layer of bandage is placed in the form, it is filled with PVA adhesive, using a bristle brush and the adhesive the bandage is distributed over the entire surface, the second layer of bandage is placed in transverse direction and poured with the adhesive, then up to 6 bandage layers are placed successively longitudinally and transversely, applying the PVA adhesive on each layer, it is dried at room temperature for 1-2 days, the article is pulled from the gypsum form, coated it with dye with the imitation of the article texture, it is varnished if necessary.

EFFECT: increase in strength and quality of the articles obtained and reduction in time of their manufacturing.

Description

The invention relates to the field of decorative art, namely to the field of manufacturing decorative sculptures.

A known method of manufacturing products from papier-mâché, including winding onto a blank cut and glued cardboard adhesive tapes, drying, sawing off a reel removed from a blank, skinning, assembling into a product, secondary skinning, varnishing, with cardboard tape coated with impregnation with natural glue and when winding onto a blank, glued with glue based on polyvinyl acetate and its derivatives, followed by tightening with a bundle of elastic material and holding for 48-60 hours at 30-40 ° C, while the assembled product after skinning a lapping surface to the ideal smooth several times abundantly impregnated varnish and dried at 60-70 ° C for the first time for 50-60 min, and in each subsequent - 15-20 minutes. (No. 2132781, B44C 5/00, B32B 13/08).

The disadvantage of this method is the complexity of the duration of manufacture.

A known method of manufacturing products by machining, which is pasting the prepared form with pieces of paper. Make it necessary at least 8-10 layers. Every two layers must dry before applying the next two. It is necessary to ensure that the pieces of paper, when pasted, slightly overlap, lie flat and do not wrinkle (see mashe /).

The disadvantage of this method is the need for applying a large number of layers of reinforcement, the duration of drying at a certain temperature, the reduction in size when drying, the lack of clarity of shape.

The objective of the invention is to improve the quality, durability and reduce the manufacturing time of products of various sizes.

This object is achieved by the fact that in the method of manufacturing sculptural and design products, including layer-by-layer reinforcement, drying, staining and varnishing, the three-dimensional shape is molded from sculpted plasticine, its surface is smeared with soap foam and filled with gypsum, after 10-20 minutes the gypsum is removed, applied 5-6 layers of vegetable oil for 10-15 minutes, then put the first layer of the bandage in the mold, fill it with PVA glue, distribute the bandage with a bristle brush and glue over the entire surface, put the second layer of the bandage in transverse board and fill with glue, then stack sequentially longitudinally and transversely up to 6 layers of bandage, applying PVA glue to each layer, dry at room temperature for 1-2 days, pull the product out of a gypsum mold, cover it with a dye with imitation of the texture of the product, if necessary varnish.

The inventive method is presented in the following images:

Photo 1 - product molded from plasticine;

Photo 2 - the resulting plaster mold;

Photo 3 - the process of bookmarking the bandage;

Photo 4 - prepared product in the form;

Photo 5 - product taken from the mold;

Photo 6 - two parts of the product;

Photo 7 - gluing two parts of the product;

Photo 8 - finished product with a touch of metal.

The method is as follows.

The three-dimensional form is molded of sculptural plasticine, its surface is smeared with soapy foam and cast with plaster. Gypsum is removed after 10-20 minutes, 5-6 layers of vegetable oil are applied for 10-15 minutes. Then the first layer of the bandage is put in the mold in the longitudinal direction, filled with PVA glue, with the help of a bristle brush and glue the bandage is distributed over the entire inner surface of the product. The second layer of the bandage is laid in the transverse direction and filled with glue. Then stack sequentially longitudinally and transversely up to 6 layers of the bandage, applying PVA glue to each layer. And it is not recommended to use gauze instead of a bandage, since when it is used in the form, folds appear.

The product is dried at room temperature for 1-2 days, the product is pulled out of a plaster mold, and if necessary, the defects are corrected with PVA glue. Then it is coated with a dye imitating the texture of the product, if necessary, varnished.

The proposed method improves the strength and quality of the products and reduce the time of their manufacture.

Claims (1)

A method of manufacturing sculptural and design products, including layer-by-layer reinforcement, drying, staining and varnishing, characterized in that the three-dimensional product is molded from sculpted plasticine, lubricated its surface with soap foam and cast with gypsum, after 10-20 minutes the gypsum is removed, 5-6 apply layers of vegetable oil for 10-15 minutes, then put the first layer of the bandage in the mold, fill it with PVA glue, distribute the bandage with a bristle brush and glue over the entire surface, lay the second layer of the bandage in the transverse direction and fill it with EEM then placed successively longitudinally and transversely to 6 layers of bandage, applying adhesive to each layer of PVA is dried at room temperature for 1-2 days, pull the product from the plaster form, it is coated with imitation billing dye product, varnish, if necessary.
