Description

Technical Field

[0001] The invention belongs to the technical field of handicraft preparation, and in particular relates to a paint wire forming handicraft and a preparation method thereof. Background Art

[0002] Lacquerware is one of the traditional Chinese handicrafts with a long history and unique artistic charm. The traditional lacquer craft requires multiple steps, including base making, back piling, surface piling, and bottom application, which are cumbersome and time-consuming. In addition, the production of traditional lacquer begins with finding a solid body of suitable material and shape (such as wood, metal, leather, debonding (paper-padded), bamboo, pottery, paper, rope, etc.). However, the process of finding a suitable base material often takes a lot of time and effort, and lacquerware based on the base often looks clumsy and heavy.

[0003] Based on this, on the basis of continuing some of the traditional lacquer piling processes, it is necessary to develop new processes to provide new materials, colors, molding methods or handicraft forms for the traditional lacquer piling process, thereby pioneering innovations in lacquer piling process methods and handicraft forms. The patent with publication number CN107284115A and invention name "Lacquer Painting and Lacquer Carving Decoration Production Method" announced a modified raw lacquer ink made from lacquer phenol extracted from raw lacquer as a resin raw material, and further announced the use of 3D printing to produce raised line effects. However, this method is relatively complicated as a whole and requires the use of additional instruments and equipment. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a method for preparing handicrafts directly formed by paint wire and paint wire formed handicrafts, which partially solve or alleviate the above-mentioned deficiencies in the prior art. The present invention specifically adopts the following technical solutions.

[0005] A method for preparing handicrafts by using paint wire molding, comprising the following steps: S01: preparing lacquer and talcum powder, wherein the mass ratio of lacquer to talcum powder is 1:3 to 2:3; adding the talcum powder to the lacquer in small amounts and multiple times, stirring thoroughly each time, to obtain a crude lacquer ash product; S02: adding fluid grease to the crude paint ash product, adding 1-3 mL of the fluid grease to every 40-60 g of the crude paint ash product, stirring thoroughly and then standing to obtain a paint wire material; S03: prepare a handheld extrusion tool and load the paint wire material into it; the handheld extrusion tool comprises a discharge end and an extrusion end; the hardness of the discharge end is higher than that of the extrusion end (to facilitate the molding of the paint wire); the top of the discharge end is open, the opening shape is circular, and the diameter is 1-3 mm; S04: setting the ambient temperature to 32-35° C. and the ambient humidity to 75-80% RH, and drawing a pre-designed pattern on a drawing board using the paint line squeezed by the handheld squeezing tool; repeatedly drawing to obtain a multi-layer paint line pattern; S05: After the drawing is completed, the ambient temperature is cooled down to no less than 20°C in a gradient manner. After the gradient cooling is completed, the ambient humidity is reduced to 40-50%RH to allow the handicrafts drawn with paint lines to be fully dried.

[0006] Furthermore, before the lacquer is mixed with talcum powder, it is first spread on a flat plate at room temperature and left to stand for 3-5 minutes.

[0007] Furthermore, the viscosity of the paint wire material is in the range of 100-300 Pa·s.

[0008] As a preferred embodiment, the viscosity of the paint line material is in the range of 200-300 Pa·s. The paint line extruded by the tool of the present invention needs to be smooth and round, and have a certain hardness and viscosity to ensure that overlapping drawings can be made on the same paint line.

[0009] Further, the drawing board includes a wooden drawing board, a wood-fiber composite drawing board or a plastic drawing board. The surfaces of these drawing boards have a certain degree of roughness, which can make the extruded paint lines better bonded.

[0010] As an optional method, a layer of lacquer paste (a mixture of paste made from glutinous rice flour and raw lacquer) is first applied on the drawing board to increase the firmness of the drawing board and make it waterproof.

[0011] As an optional method, a pre-designed pattern can be drawn on a drawing board with a pen; the pre-designed pattern includes node marks indicating the drawing length of the paint line.

[0012] Furthermore, the volume of the paint wire material loaded into the handheld extrusion tool at a single time is no more than 50 mL.

[0013] As a preferred embodiment, the fluid grease contains antioxidants.

[0014] Furthermore, the gradient cooling is specifically as follows: cooling to 30° C. and maintaining for 1 hour; cooling to 25° C. and maintaining for 3 hours; cooling to 20° C. and maintaining until the paint wire is completely dry.

[0015] The present invention adopts a gradient cooling method to ensure that the paint wire can be firmly bonded to the plane or the paint wire of the lower layer during the drying process, and the completely dried paint wire will not collapse or crack.

[0016] Furthermore, in the process of drawing the paint lines, after each paint line is drawn, it is left to stand for at least 5 minutes under the conditions of an ambient temperature of 32-35°C and an ambient humidity of 75-80%RH, and then the paint lines are continued to be superimposed and drawn; the number of layers of the multi-layer paint lines is not more than 10 layers.

[0017] As a preferred implementation, the multi-layer paint wire has 7 layers.

[0018] Furthermore, the multi-layer paint line is arranged from top to bottom as an upper paint line, a middle paint line and a lower paint line; the mass ratio of lacquer to talcum powder in the upper paint line is 1:3 (the proportion of talcum powder is large, and the paint line is hard); the mass ratio of lacquer to talcum powder in the middle paint line is 1:2 (the proportion of talcum powder is moderate); the mass ratio of lacquer to talcum powder in the lower paint line is 2:3 (the proportion of talcum powder is small, and the paint line is soft.

[0019] As a preferred implementation, from top to bottom, the 1st to 3rd layers of paint lines are set as upper layers of paint lines; the 4th to 5th layers of paint lines are set as middle layers of paint lines; and the 6th to 7th layers of paint lines are set as lower layers of paint lines.

[0020] Furthermore, the pre-designed pattern may include decorations made of other materials.

[0021] The lacquer wire forming handicraft prepared by the above method.

[0022] Beneficial technical effects: (1) The present invention provides a method for directly using molded paint lines to produce a handicraft of a predetermined shape or pattern without the need for a model or blank, or other equipment or instruments. The handicraft produced forms a stable multi-layer structure, and the entire three-dimensional handicraft finally formed does not collapse or crack. Therefore, the paint line molding technology provided by the present invention is an extension and decomposition of the traditional paint piling process.

[0023] (2) The present invention provides an innovative material, which adds talcum powder to traditional lacquer to increase the hardness of the lacquer line, and further adds fluid grease to increase the uniformity and smoothness of the lacquer line. The lacquer line extruded by this innovative material can be drawn not only on a single plane, but also in multiple layers, with each layer of lacquer line firmly bonded to each other, and the entire handicraft does not collapse or crack. Specifically, in order to draw a multi-layer lacquer line work of qualified quality and to maintain its shape for a long time without collapse, the proportion of lacquer and talcum powder is different when preparing the material. In the lacquer line material, the proportion of talcum powder gradually increases, and the texture of the lacquer line obtained gradually becomes harder and heavier. The lacquer line with the hardest texture is in the uppermost layer, the lacquer line with a moderate texture is in the middle layer, and the lacquer line with the softest texture is in the lowermost layer (i.e., the texture of the lacquer line gradually becomes softer from top to bottom). In this way, when the upper layer of lacquer line is bonded to the lower layer of lacquer line, the lower layer of lacquer line with a softer texture can be slightly concave and deformed, thereby increasing the contact area between the lacquer lines and forming a more stable bond.

[0024] (3) To further meet the characteristics of the paint line material, the present invention also proposes high temperature and high humidity operating conditions so that the extruded paint line will not dry too quickly. In this high humidity environment, the paint line of the upper layer will slightly overflow and deform outward when it is extruded, increasing the contact area with the surface of the lower layer of paint line, and also promoting the formation of a more stable bond. After the overall drawing is completed, the temperature is first lowered and then the humidity is lowered, and then a fixed low humidity environment is maintained so that the paint line craftwork will not collapse or crack after it is fully dried.

[0031] In this specification, some embodiments may be disclosed in a format of being in a range. It should be understood that this description of "being in a range" is only for convenience and brevity, and should not be interpreted as a rigid limitation on the disclosed range. Therefore, the description of the range should be considered to have specifically disclosed all possible sub-ranges and independent numerical values ​​within this range. For example, the description of the range 1-6 should be considered to have specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as individual numbers within this range, such as 1, 2, 3, 4, 5 and 6. Regardless of the breadth of the range, the above rules apply.

[0032] Example 1 This embodiment provides an example of a method for preparing a handicraft using paint wire molding.

[0033] Prepare the materials for making the paint thread: S01: Spread an appropriate amount of lacquer and place it on a flat plate, and place it in a cool place at room temperature for 3-5 minutes to activate the lacquer phenol contained in the lacquer. Then add an appropriate amount of talcum powder to the lacquer three times, stir it thoroughly after each addition of talcum powder, and finally fully blend the talcum powder and the lacquer to obtain a crude lacquer ash product. The mass ratio of lacquer to talcum powder ranges from 1:3 to 2:3. According to the convenience of operation, 3 portions of crude lacquer ash can also be prepared at a time. In different portions of crude lacquer ash, the mass ratio of lacquer to talcum powder is 1:3, 1:2 and 2:3 respectively.

[0034] S02: Add an appropriate amount of fluid grease to the stirred and mixed crude paint ash for blending and dilution. Add 1-3 mL of fluid grease to every 40-60 g of crude paint ash, and then let it stand for 3-5 minutes. After the mixture presents a stable state with obvious granularity, the paint wire material is obtained. Take a small amount of the prepared paint wire material and measure its viscosity value with a tube viscometer. By adjusting the amount of crude paint ash or fluid grease added, the viscosity range of the paint wire material is 100-300 Pa·s.

[0035] You can add a small amount of antioxidants to the oil to keep the paint color bright, or you can directly choose oils with antioxidant ingredients, such as orange oil.

[0036] S03: prepare a handheld extrusion tool, further load the prepared paint wire material, the front section of the handheld extrusion tool is open, the opening shape is circular, and the opening diameter is 1-3mm. The paint wire extruded by the handheld extrusion tool is cylindrical.

[0037] The process of painting with paint thread: S04: Set the ambient temperature to 32-35℃, set the ambient humidity to 75-80%RH, and use the cylindrical paint line squeezed out by the handheld extrusion tool to draw a pre-designed pattern on the wooden drawing board. Different colors of paint can be used in each layer of paint line pattern according to the color requirements of the work. In the process of drawing the paint line, after each paint line is drawn, let it stand for at least 5 minutes under the environmental conditions, and then continue to draw on the paint line. Multiple layers of paint lines can be repeatedly drawn according to the needs of the work creation, but no more than 10 layers.

[0038] S05: After the drawing is completed, the ambient temperature is cooled down to no less than 20°C in a gradient manner. After the gradient cooling is completed, the ambient humidity is reduced to 40-50%RH to allow the handicrafts drawn with paint lines to be fully dried.

[0039] The operation diagram of this embodiment is shown in Figure 1 , where the partial schematic diagram of the bonding between the paint lines is shown in Figure 2It is understandable that the paint lines extruded by the innovative paint line material of the present invention are not limited to drawing one layer on a plane, but can be drawn in multiple layers, and each layer of paint line is fully bonded to form a stable multi-layer structure, so that the entire three-dimensional handicraft will not collapse or crack.

[0040] Example 2 This embodiment provides an example of drawing multiple layers of paint lines in an overlapping manner.

[0041] Table 1 Multi-layer paint line and material ratio See the schematic diagram Figure 3 , the total mass of the upper paint line is heavier (because the talcum powder accounts for the largest proportion), the paint line texture is the hardest, and the texture of the paint line from the middle layer to the lower layer gradually becomes softer (the proportion of talcum powder gradually decreases). When the upper paint line is bonded to the middle paint line and the middle paint line is bonded to the lower paint line, the softer layer of paint line can be slightly concave and deformed, thereby increasing the contact area between the paint lines and forming a more stable bond. In addition, because the paint lines are drawn in a high humidity environment, the upper layer of paint lines will have a slight outward overflow deformation when they are squeezed out, increasing the contact area on the surface of the next layer of paint lines, which also promotes the formation of a more stable bond.

[0042] Example 3 This embodiment provides a specific operation example of preparing handicrafts by using paint wire molding.

[0043] S01: Place 20g of lacquer on a flat plate and leave it in a cool place at room temperature for 3-5 minutes to activate the lacquer phenol contained in the lacquer.

[0044] S02: Then, 30 g of talcum powder is added to the lacquer three times, and each time the talcum powder is added, the mixture is stirred thoroughly, and finally the talcum powder and the lacquer are fully blended to obtain a crude lacquer ash product. The purpose of adding the talcum powder three times is to stir the mixture more evenly.

[0045] S03: Dilute 2 mL of orange oil into the stirred and mixed crude paint ash, and then let it stand for 3-5 minutes. After the mixture presents a stable state with obvious granularity, the finished paint ash product is obtained, and its viscosity value is measured with a tube viscometer. Then take 50 mL and put it into a decorating bag, wherein the front end (discharging end) of the decorating bag has an opening of 1-3 mm. In addition, a cardboard is pre-set at the front end of the decorating bag to make the front end of the decorating bag have good hardness.

[0046] S04: Draw the pre-designed pattern on the drawing board with a pencil in advance.

[0047] S05: Use air conditioning or other heating devices to set the ambient temperature to 32-35°C and stabilize it; use a humidifier to raise the ambient humidity to above 75% and stabilize it. Use the paint line squeezed out of the piping bag to draw the pre-designed pattern, and squeeze out several layers repeatedly according to the needs of the work creation. The pre-designed pattern contains beads or block sequins decoration. The operation diagram of drawing the paint line in this embodiment is shown in Figure 4 .

[0048] S06: After drawing is completed, first cool the ambient temperature to 30℃ and keep it for 1h; then cool it down to 25℃ and keep it for 3h; then cool it down to 20℃ and at the same time reduce the ambient humidity to 40-50%RH and keep it until the paint line is completely dry.

[0049] Example 4 This embodiment provides another specific operation example of preparing handicrafts by using paint wire molding.

[0050] S01: Place 10g of lacquer on a flat plate and leave it in a cool place at room temperature for 3-5 minutes to activate the lacquer phenol contained in the lacquer.

[0051] S02: Then, 30 g of talcum powder is added to the lacquer three times, and each time the talcum powder is added, the mixture is stirred thoroughly, and finally the talcum powder and the lacquer are fully blended to obtain a crude lacquer ash product. The purpose of adding the talcum powder three times is to stir the mixture more evenly.

[0052] S03: Dilute the crude paint ash product with 1.5 mL of olive oil after stirring and mixing, and then let it stand for 3-5 minutes. After the mixture presents a stable state with obvious granularity, the finished paint ash product is obtained, and its viscosity value is measured with a tube viscometer. Then take 50 mL and put it into a decorating bag, wherein the front end (discharging end) of the decorating bag has an opening of 1-3 mm. In addition, a cardboard is set in advance at the front end of the decorating bag to make the front end of the decorating bag have good hardness.

[0053] S04: Set the ambient temperature to 32-35℃ and stabilize it; at the same time, raise the ambient humidity to above 75% and stabilize it. Use the paint line squeezed out of the piping bag to draw the pattern.

[0054] S05: After drawing is completed, first cool the ambient temperature to 30℃ and keep it for 1h; then cool it down to 25℃ and keep it for 3h; then cool it down to 20℃ and at the same time reduce the ambient humidity to 40-50%RH and keep it until the paint line is completely dry.
