Method of creating patterns with a 3D effect on the surface of semi-finished products and products made of dry bulk

Abstract

The method of creating patterns with a 3D effect on the surface of semi-finished products and products made of dry bulk is based on the fact that dry bulk with a granulometry of 0.01mm to lOmm is poured into a circurnferential mould and its surface is levelled. The 3D element is imprinted on the surface and when removed, paint is sprayed on the surface with the 3D element irnprint at an angle of 89° to 1°; the subsequent further levelling of the surface creates a pattern with a visual 3D effect. Dry bulk in the mould and the surface after the creation of the irnprint by the 3D element is levelled by pressing, rolling, vibration or a combination thereof.

Description

[0001] Method of creating paterns with a 3D effect on the surface of semi-finished products and products made of dry bulk

[0002] Technical field

[0003] Die method of creating patterns with a 3D effect on the surface of semi-finished products and products made of dry bulk allows wide application, especially in the construction industry.

[0004] Current state of the art

[0005] The creation of the above-mentioned patterns is applied to materials the plasticity of which allows ductile deformation under the action of small external forces. Previously known decorations, created on the surface of dry bulk, which is subsequently compacted, are usually only coloured without a plastic 3D effect.

[0006] Background of the invention

[0007] The above disadvantages are eliminated by the method of creating patterns with a 3D effect on the surface of semi-finished products and products made of dry bulk according to the invention, the principle of which is that dry’ bulk with a granulometry of 0.01-10mm is poured into the circumferential mould, the surface of the mould is levelled by compacting and a 3D element is imprinted on the surface. Compacting of dry bulk in the mould is done by pressing, rolling, vibration or a combination thereof. After removing the 3D element, paint is sprayed on the surface with the 3D element imprint at an angle of 89° to 1°. Subsequent compacting of the surface creates a pattern with a visual 3D effect. After the 3D element is imprinted, the surface is compacted by pressing, rolling or pressing together with the action of vibrations. If the created pattern is to be resistant to external forces, it is necessary to add reinforcing components to the dry bulk. Another option is to stabilize the created pattern with a transparent plate or expose the dry bulk to a temperature at which the dry bulk becomes a solid whole. The imprint of the element is made by a 3D element created on a straight die or by a die placed on a cylinder.

[0008] Suitable materials for the production method according to the invention are such semi-finished products where the necessary plasticity and later strength of the product is ensured by the interaction of forces between particles or the addition of other components such as water, acrylates, cements, resins, etc. The plasticity of the material is also affected by the shape of individual particles and the mutual force bonds between the individual particles. These car, be affected primarily by choosing the right type of material and admixture of additional material to obtain the required plasticity. Correct granulometry affects both the plasticity of the material and the accuracy of the imprint. It is preferable to use materials consisting of multiple size fractions.

[0009] The resulting 3D effect of the pattern is also affected by the depth of the imprint; the smaller the plasticity of the material, the more it is necessary' to reduce the depth of the imprint to prevent the destruction of the imprint when removing the die from the pattern or only when the force of gravity is applied. The depth of the imprint affects the resulting 3D effect; the smaller the plasticity of the material, the more it is necessary to reduce the depth of the imprint to prevent the destruction of the imprint when removing the die from the pattern or only when the force of gravity is applied. Large depth of the Imprint has a negative effect on the sharpness of the pattern, due to the destruction of the imprint when comparing the surface.

[0010] The angle of the pigment application direction fundamentally affects the creation of a high- quality pattern with a 3D effect. The imprint disappears after comparing the surface at an angle of 90° between the surface and the pigment application direction as a result of the pigment uniformly painting the surface. Unpainted areas are created by gradually reducing the angle due to being shaded. On the contrary, by exceeding the optimal, angle of pigment application towards lower angle values, the unpainted areas become larger and the resulting pattern loses its contours and is blurred. Examples of Invention

[0011] Example 1

[0012] Sand with a granulometry of 0.1 to 3mm with a material moisture content of about 9% is used to create a 3D element. The material is compacted by pressing or rolling in a circumferential mould of any shape and a 3D element on a die is printed into the surface. After removing the element, the surface is spray-painted at an angle of 40° and compacted again by pressing or rolling. Contrast pigments can be used as a paint to match the colour of dry bulk. The plasticity of these materials, together with the application of paint at the right angle, will create the desired pattern with a plastic 3D effect. This method of creating a 3D pattern can be used when decorating, for example, building elements.

[0013] Example 2

[0014] Pottery clay with a granulometry of 0.1 to 0.5mm mixed with a reinforcing component, in this case water, is used to create a 3D element. The material is compacted by pressing or rolling in a circumferentiai mould of any shape and a 3D element on a die is printed into the surface. After removing the element, the surface is spray-painted at an angle of 50® and compacted again by pressing or rolling. Contrast pigments can be used as a paint to match the colour of dry bulk. The plasticity of these materials, together with the application of paint at the right angle, will create the desired pattern with a plastic 3D effect. In this case, the pattern will be stabilized on the item by the temperature while firing the ceramic. This method of creating a 3D pattern can be used when decorating, for example, ceramics.

[0015] Industrial applicability

[0016] The method of creating patterns with a 3D effect can be used, in the production of building elements such as fence elements, building blocks, concrete tiles, concrete paving, etc., in the ceramic industry to decorate ceramics, in the glass industry to decorate glass products and also in the food industry to decorate confectionery products.
