Description

The invention relates to multi-layered materials with drawing and adhesive surface properties, intended for the manufacture of reusable drawing elements in drawing and graphic works.

A multilayer material is known, consisting of a transparent polyester substrate and a matting front layer containing a mixture of copolymers of vinyl chloride with vinyl acetate and vinyl chloride with vinylidene chloride or a mixture of cellulose triacetate and copolymer of terephthalic acid with diethylene glycol and the filler il,

A disadvantage of the known multilayer material is the limited scope of application, in particular, it cannot be used for the manufacture of reusable drawing elements in drawing and drawing works.

The aim of the invention is to create a material for the manufacture of elements of multi-use drawings in drawing and graphic works.

 The essence of the invention is that the known material on the opposite side of the face layer has an adhesive layer that contains a 30-50% aqueous dispersion of a copolymer of butyl acrylate and vinyl butyl ether at a ratio of from 4: 1 to 4: 2 and 30-50% aqueous dispersion of vinylacetate copolymer and acrylic acid at a ratio of 15: 84: 1 to 49: 49: 2 in the following ratio of components.%:

30-50% water

butyl acrylate copolymer dispersion. that and vinyl butyl ether 20-50

30-50% water

Vinylacetate copolymer dispersion,

Acrylic Acid Else.

In order to protect the adhesive layer, the material may additionally have a protective layer of siliconized or waxed or polyethylene paper on the adhesive layer.

A multilayered material of such composition possesses adjustable adhesion sufficient to prevent spontaneous movement on the base during the execution of drawing works and ensures the safety of the face matted base layer after its removal; solidity in the final fixation of a material with a sticky layer based on prolonged contact (the effect of accretion), due to the presence in the adhesive layer and the drawing basis of components with similar functional groups and the transfer of the polymer adhesive layer from flowing into a highly elastic state; the basis of the drawing and the proposed long-term contact during the process. It is provided only when the content of vinyl acetate Tai in the copolymer dispersion ranges from 15 to 49%. Such material properties allow it to be used for the mechanization of graphic works using the method of flat-bone design.

The material is obtained by successively applying to the transparent polyester substrate a facial matting coating on one side and an adhesive layer on the other side.

The temperature mode of drying the adhesive layer: Zone I is 40-50 ° C, Zone II with the substrate moving speed of 0.4-4.0 m / min. After removing the solvent from the adhesive layer, a protective layer of siliconized, waxed, or polyethylene paper is rolled into it. Example

Multilayer material with peryJiHpyeMBiifH adhesiveness is achieved through the mechanization of drawing and graphic works in design and structural work through the introduction of new progressive technology for compiling technical documentation of the plane-plane method. The essence of the method lies in the fact that the types of elements of the drawing, made on the proposed material, can be applied to the sub-foundation of the drawing due to the sticky properties. When creating variants, it is not necessary to redraw each variant anew, it is sufficient to transfer, according to the new layout, the typical elements made on the proposed material and complete the drawing with connecting lines of communication. When transferring a typical specimen made on the proposed mother and ale, the integrity of the drawing base on which the installation is carried out is not disturbed. Thus, dramatically increases the productivity of the designer, improves the quality of documentation and reduces the time it takes to complete it.
