Description

Technical Field

[0001] This invention relates to the field of art creation materials technology, and in particular to liquid painting materials and painting methods based on modified black powder. Background Technology

[0002] Traditional painting art mostly uses conventional pigments such as oil paint, watercolor, and acrylic. In order to pursue unique visual impact and artistic effects, artists are constantly exploring new creative media. Gunpowder, as a combustion material, has been used by artists to create explosive burning effects on canvas, forming unique burn marks and images.

[0003] In the prior art, such as Chinese invention patent application with publication number CN118290210A, a method for preparing and applying a liquid flow material for making fireworks effects is disclosed. This technology prepares a liquid material by mixing pigments, additives and gunpowder (such as a mixture of potassium chlorate, starch and clay) in a solvent. After being drawn, dried and ignited, it produces fireworks flames and carbonization marks.

[0004] However, the existing technology and traditional gunpowder painting methods have the following significant defects: (1) Single artistic effect: mainly relies on carbonization traces after combustion, the color is monotonous, lacking rich color layers other than black, and its "pigment" mainly plays the role of painting, contributing little to the color after combustion; (2) Poor controllability: the combustion process focuses more on simulating the spray effect of "fireworks", the combustion trajectory, range and the final pattern left are too random, making it difficult for artists to make fine guidance and composition; (3) Questionable safety: using oxidants such as perchlorate to directly mix with combustibles, its combustion performance is closer to micro fireworks, and improper control may lead to unpredictable rapid combustion; (4) Unable to achieve delicate brushstrokes and color presets in liquid painting: traditional methods cannot use gunpowder as a "pigment" with preset colors for painting, smearing and blending, and its visual effect after combustion is weakly related to the painting process.

[0005] Therefore, there is an urgent need in this field for a new type of painting material and painting method that can retain the unique artistic characteristics of gunpowder combustion, while also having higher safety, stronger controllability, and the ability to achieve rich and predictable colors. Summary of the Invention

[0006] Based on the technical problems existing in the background art, the present invention proposes a liquid painting material and painting method based on modified black powder. The painting material transforms gunpowder into a liquid "pigment" that can be safely stored and is easy to operate with a paintbrush. After combustion, it can form unique, controllable and colorful burn textures on the paper surface.

[0007] The present invention proposes a liquid painting material based on modified black powder, comprising the following components in parts by weight: 0.5-1.2 parts black powder powder, 0.1-0.4 parts combustion accelerant, 0.1-0.5 parts metal oxide colorant, 0.3-1 parts thickener, and 1-3 parts diluent.

[0008] Preferably, the mixed particle size of the black powder and the combustion accelerant is less than 100 mesh.

[0009] Preferably, the combustion aid is potassium chlorate or benzoyl peroxide.

[0010] Preferably, the metal oxide colorant is one or more of manganese dioxide, copper oxide, and ferric oxide.

[0011] Preferably, the thickener is glycerin or acetone.

[0012] Preferably, the diluent is a C1-C4 alcohol solvent.

[0013] This invention proposes a painting method based on modified black powder liquid painting material, the modified black powder liquid painting material is as described above, and the method steps are as follows:

[0014] S1: Mix black powder, combustion aid, metal oxide colorant and thickener, then add diluent and stir to form a uniform suspension;

[0015] S2: The suspension is applied to the substrate to form a pattern, and after drying, a cured film is formed;

[0016] S3: Use a controllable heat source to ignite the solid film, creating burn marks on the substrate with the color of metal oxide colorant, thus completing the painting.

[0017] Preferably, the substrate is one of Xuan paper, watercolor paper, and sketch paper.

[0018] Preferably, in S2, the suspension is applied to the substrate using a brush or a spray brush.

[0019] Preferably, the controllable heat source in S3 is one of an electric soldering iron, incense stick, and electric igniter.

[0020] Mechanism of action

[0021] The mechanism of the "synergistic effect of metal oxide colorants and specific solvent systems" described in this invention lies in the fact that the liquid environment jointly formed by the thickener and diluent is not merely a physical dispersion medium, but an active system that participates in and plays a key role throughout the entire process from pretreatment and combustion process control to final color development. This synergistic effect is specifically manifested in the following three aspects:

[0022] 1. Construction of the "micro-reaction environment" in the pretreatment stage

[0023] The thickeners (such as glycerol and acetone) of this invention exhibit excellent wetting and dispersing capabilities for metal oxide colorants and black powder. During the process of stirring to form a suspension, the thickener molecules can uniformly coat the surface of the solid particles, creating a temporary, energy-rich "micro-reaction environment." This pretreatment allows the metal oxide colorants and energetic components to achieve close molecular-level contact before combustion occurs, creating favorable conditions for electron transfer and catalytic activity in the subsequent combustion process.

[0024] 2. Energy and mass transfer regulation during combustion

[0025] Thickeners as Secondary Combustibles and Mass Transfer Barriers: Thickeners themselves (such as glycerin) can participate in combustion as combustibles, but their liquid nature and high boiling / decomposition temperature cause them to form a gas-liquid interface in the early stages of combustion. This interface slows down the mass and heat transfer rates between the oxidizer and the combustible. This creates a subtle "antagonistic balance" with the catalytic effect of metal oxide colorants (such as CuO, Fe2O3): the catalytic effect tends to accelerate the reaction, while the physical barrier formed by the solvent system tends to slow it down. The combined effect of these two factors transforms the inherently violent deflagration of black powder into the slow, stable, surface-spreading smoldering required by this invention. This controlled combustion mode is a prerequisite for preserving brushstrokes and achieving uniform color development.

[0026] Diluents act as "shapers" of combustion patterns: the rapid evaporation of diluents (such as ethanol) leaves microporous structures in the dried solid film. These micropores, upon ignition, regulate the diffusion of oxygen and the exhaust path of combustion products, enabling combustion to spread directionally and orderly along the drawn lines, rather than spreading randomly, thus achieving high fidelity and controllability of the combustion path.

[0027] 3. Fixing and Enhancement of the Final Color Rendering Effect

[0028] Because the combustion process is a gentle smoldering rather than a violent deflagration, its peak temperature is much lower than the temperature at which solid gunpowder is directly ignited. This mild thermal environment avoids sintering, discoloration, or phase transformation of metal oxide colorants due to excessively high temperatures, ensuring the stability and accurate reproduction of their inherent colors.

[0029] Meanwhile, the small amount of amorphous carbon produced by the incomplete combustion of the thickener intertwines and complements the colors of the metal oxides, forming richer, deeper, and uniquely textured color layers and carbonization traces, which together constitute the final artistic effect.

[0030] Beneficial technical effects

[0031] (1) By introducing specific metal oxide colorants, the present invention can leave various colors such as ochre, dark green, and brownish black on the substrate after combustion, breaking through the limitation of single color in traditional gunpowder painting. Moreover, the color is directly related to the metal oxide colorant selected during painting, with predictability.

[0032] (2) By using a modified black powder base system, adding metal oxides to regulate the combustion process, and adopting a safe and controllable heat source such as an electric soldering iron, the present invention realizes the controllability of the combustion process; artists can perform fine composition like using traditional pigments, and the combustion path can be effectively guided, achieving a leap from "random blasting" to "controllable burning drawing".

[0033] (3) The present invention converts high-energy black powder into a liquid suspension system, reducing the risk of dust explosion during storage and operation; the combustion process is slow surface smoldering rather than violent deflagration, which is easy to control.

[0034] (4) The painting method of the present invention perfectly combines the beauty of flowing and blending in liquid painting with the beauty of etching marks in gunpowder combustion, and at the same time superimposes the color charm of metal oxides, providing artists with an unprecedented art expression medium. Brief Description of the Drawings

[0035] Figure 1 It is the effect diagram of the painting created using the materials of the present invention in Example 1 proposed by the present invention. Detailed Embodiments

[0036] The present invention will be further explained below in conjunction with specific embodiments. Example 1

[0037] First, weigh 0.8 g of black powder and 0.2 g of potassium chlorate (mixed particle size less than 100 mesh) and place them in a beaker. Add 0.02 g of copper oxide powder and 0.5 g of glycerin; then add 1 mL of ethanol, put in a magnetic stirrer, seal and stir at 400 rpm for 30 minutes to obtain a uniform suspension.

[0038] Then, select a piece of imitation Xuan sketch paper with a weight of 80 g / m 2 as the substrate and fix it on a steel drawing board; dip a medium-sized wolf hair brush into the above liquid material and write words such as "Heaven and Earth, Mysterious and Yellow" on the paper to show the brushstrokes; place the work in a 65 °C blast drying oven and dry it for 30 minutes to form a solid film.

[0039] Finally, ignite the starting point of the handwriting with a lit incense stick, and the solid film burns slowly and steadily along the handwriting, accompanied by blue-white smoke; after the combustion stops, the handwriting with the unique green-brown tone of copper oxide formed by burning remains on the paper, with smooth brushstrokes and a unique carbonized halo at the edge; after the picture cools, spray fixative for color fixation and sealing. Example 2

[0040] First, weigh 0.7g of black powder and 0.3g of potassium chlorate (mixed particle size less than 100 mesh) and place them in a beaker. Add 0.03g of ferric oxide powder and 0.3g of glycerol. Then add 1mL of ethanol, place a magnetic stir bar in the beaker, seal it, and stir at 400rpm for 30 minutes to obtain a uniform suspension.

[0041] Then, select a sheet of 180g / m 2 Watercolor paper is used as a base and fixed to a steel drawing board; abstract patterns are drawn with a brush; the artwork is placed in a 40℃ drying oven for 40 minutes to form a cured film.

[0042] Finally, the edge of the pattern is ignited using a soldering iron tip, and the combustion spreads in a controlled manner. After burning, a unique texture of ochre red and carbon black interwoven by ferric oxide is formed on the substrate. After the image cools, fixative is sprayed to fix the color and seal it. Example 3

[0043] First, weigh a mixture of 0.5g black powder and 0.5g potassium chlorate (mixed particle size less than 100 mesh) into a beaker, add 0.05g manganese dioxide powder and 0.4g acetone, then add 2mL ethanol, place a magnetic stir bar in the beaker, seal it, and stir at 600rpm for 30 minutes to obtain a uniform suspension.

[0044] Then, select a sheet of raw Xuan paper that has been lightly flame-retardant treated as a base and fix it on a solid wood drawing board; use a mixed-hair brush dipped in the above liquid material, first use the central tip to outline the contours of the rocks and trees, and then adjust the dryness, wetness, thickness and lightness of the brush tip and the side tip of the brush to express the shape and texture of the rocks; after the painting is completed, place the work in the dark at room temperature to dry naturally for 2 hours to form a solid film.

[0045] Finally, a lit incense stick is used to ignite the ridgeline area in the painting. After the solid film is ignited, the flame spreads slowly and in a controlled manner along the mountain's contours. After the burning stops, the Xuan paper is left with a mountain structure, mainly dark gray-black, formed by the catalytic combustion of manganese dioxide, and the outline of the rocks is clearly preserved. After the painting cools down, fixative is sprayed to fix the color and seal it. Example 4

[0046] First, weigh 1.0g of a mixture of black powder and benzoyl peroxide in a mass ratio of 3:1 (mixed particle size less than 100 mesh) and place it in a beaker. Add 0.01g of ferric oxide powder and 0.3g of propylene glycol, stir initially with a glass rod for 5 minutes, then add 1mL of ethanol, place a magnetic stir bar in the beaker, seal it, and stir at 400rpm for 30 minutes to obtain a uniform black suspension.

[0047] Then, select a sheet of 180g / m 2 Use coarse-textured watercolor paper as a base and fix it on the drawing board; use a medium-sized wolf hair brush to dip into the above liquid material and follow the Chinese painting method of "writing bamboo" to outline the bamboo stalks and leaves with the central brush stroke; after the painting is completed, place the work in a 40℃ forced-air drying oven to dry for 40 minutes to form a solid film.

[0048] Finally, using lit incense sticks to ignite the bamboo leaves, the solid film slowly and steadily smolders along the shape of the bamboo leaves and stalks. After the burning stops, a distinct artistic effect is left on the watercolor paper: the bamboo leaves show a clear ochre color due to the ferric oxide, while the bamboo stalks form a natural gradient from brownish-black to jet black due to different degrees of carbonization. After the painting cools, fixative is sprayed to fix the color and preserve it.

[0049] To demonstrate the progressiveness of this invention, a comparison is made with the method described in Example 1 of CN118290210A as a comparative example:

[0050] (1) Color performance: The traces after burning in the comparative examples are almost all black carbon traces. Examples 1, 2 and 4 of this invention show obvious greenish-brown, ochre-red and ochre tones respectively.

[0051] (2) Combustion speed: The comparative example burns relatively quickly, accompanied by sparks. The embodiment of the present invention burns stably, with surface smoldering. The average combustion speed is reduced by about 40%, making it easier to control.

[0052] (3) Stroke reproduction: The pattern boundary is blurred after the comparative model is burned. Since the combustion is controllable, the present invention can better preserve the brushstroke details when drawing.
