Example 5

Regarding the durability of the time that can be maintained after the rosin ink of the present invention is applied to gourd carving, the present inventors conducted the following experiment:

the calabash handicraft in the attached fig. 2 is manufactured in 3 months in 2010, and the calabash handicraft does not fade until 4 middle days in 2022; the portion in which the color appears black is completed using the rosin ink of the present invention.

The calabash artware in the attached figures 3-6 is an artware which is manufactured for more than 8 years, and the engraved patterns on the calabash still keep the original color after being placed for a long time. The rosin ink is applied to gourd carving, does not fade for a long time, and does not generate oil; it will not spill in humid weather.

Comparative product 1: in the invention, the method is characterized in that: printer ink (common commercial ink-jet printer ink, namely dye ink, is formed by blending the dye ink and vegetable oil according to a certain proportion, for example, the printer ink is mixed with peanut oil which is commonly adopted in the industry at present, and can be blended with other oils, such as olive oil, soybean oil, corn oil, sunflower seed oil, castor oil, cottonseed oil and the like, and all plants which can lubricate and enable the dye ink to be adsorbed to the carved nicks of the gourd can be used);

TABLE 1 durability of rosin inks of the present invention compared to commercial conventional inks

The above-mentioned rosin ink of the present invention is prepared by the method of the present invention, and the method is the same as in example 1.

(1) With respect to persistence

Because the formula and the method of the invention are ancestral methods, generation-by-generation, and regarding the durability, the product can completely reach no fading for 20 years (or no obvious fading observed by naked eyes), many of the products mentioned in the invention have been stored for more than 20 years, and the nicked part dyed by the rosin ink is still intact till now, and the ink is black like paint; products which are stored for more than 10 years are not faded from the date of carving, dyeing and drying; the product of the invention has good durability, because in the formula of the invention, the pine needles, pine branches and pine barks are used as raw materials to prepare the components containing the rosin oil (the mixture of burnt ash and the rosin oil, black and blocky structures), wherein the rosin oil component plays a role in lubrication and emulsification on one hand, and has harmonious property and permeability to enable various materials to be better mixed, diluted and dissolved; on the other hand, the turpentine oil has strong adhesion, so that the color of plant ash (or called as carbon black or carbon black) is tightly adsorbed in the engraved patterns on the surface of the gourd, so that the plant ash is firmly adhered in the lines of the patterns, and the falling off is avoided; the turpentine oil also has a function of being fully mixed with components such as plant ash and the like, and has a barrier function like a transparent cover outside the color of the plant ash to protect the color of the plant ash from being oxidized by the components in the outside air and being not washed by the outside moisture or rain water, so that the color is durable and not faded.

The lard oil has the effects of strong lubricity and good moisture retention performance, so that the turpentine ink is not easy to evaporate or dry, the humidity of the turpentine ink is kept, and the turpentine oil is assisted; the black color produced by hand making is easier to be absorbed in the lines of the carved patterns, the hand feeling is more moist when the color is rubbed, and the color rubbing is easier to succeed; and the rosin ink and the rosin oil have synergistic effect, so that the rosin ink has more adhesiveness, and a transparent protective layer is formed outside the color of the rosin ink, so that the carved product is durable and does not fade;

plant ash, which provides the color of black carbon black for dyeing, so that the final rosin ink presents black;

brown sugar powder: can blend the over-strong black of plant ash (grass carbon) to make the color of the plant ash black with light feeling;

the bait tea powder contains tea polyphenol which contains a large amount of phenolic hydroxyl, and the phenolic hydroxyl is combined with cellulose and other components in the cucurbit skin to form hydrogen bonds and hydrophobic bonds, so that the colored cucurbit artware is not easy to fade after being wetted, and the color is more durable; meanwhile, the black color rubbed by the rosin ink is softer and cannot be too strong due to the use of the bait tea powder;

the honey contains sugar which has excellent adhesion performance, so that various raw materials can be combined together more tightly, and a firm protective barrier is formed for the color of plant ash. And the honey and the rosin oil have brightness, so that the whole rosin ink presents a fine, smooth and bright appearance, and the rosin ink is rubbed on the gourd to form high unification with the smoothness of the gourd surface, thereby being beneficial to improving the visual aesthetic feeling.

The printer ink is also commercially available for coloring gourd sculptures, but the printer ink is very likely to fade with time when used for gourd sculptures. On the one hand, it is well known in the industry that the cause of ink fading is mainly the irregular distribution of the circumferential patterns and non-patterns of the plate cylinder, while the non-printing cylinder gap also has an effect and lateral cross-inking affects ink fading. The coloring object in the invention is a calabash handicraft article, which is a product carved by hand, colors are rubbed in the engraved grooves or nicks on the surface of the calabash, and the engraved grooves or nicks are sunken in the surface of the calabash.

On the other hand, dye ink is susceptible to fading due to ultraviolet rays, ozone, and other components in sunlight, which is why ordinary photographs are susceptible to yellowing and fading. Meanwhile, the dye ink also has the phenomena of ink seepage or fading and the like caused by moisture absorption and easy moisture absorption, so that the color fastness of the dye ink is also poor.

Therefore, compared with the common printer ink, the rosin ink product is derived from natural plant and animal grease, has no artificially synthesized chemical components in dye ink, and has stronger durability.

(2) With respect to oil-bleeding, spillage or leakage

The rosin ink is applied to gourd carving, so that the phenomenon that the pattern at the carving and dyeing position is leaked and spilled out of the nicks due to high moisture absorption or deliquescence of air in rainy days is avoided, the phenomenon of oil leakage is avoided, and the phenomenon of oil leakage or oil leakage can be observed by naked eyes.

The judgment of the phenomena of spilling and oil leakage is to adopt a common paper towel to wipe the carved part back and forth and observe whether the paper towel has black pollution or oil stain. The rosin ink prepared by the method is carved on the gourd and then dried, and after the rosin ink is placed for 30 days, the method is adopted to judge in rainy days, so that black pollution and oil stain are avoided, which shows that the rosin ink dyed in the method has no oil seepage and spilling phenomenon and oil seepage phenomenon in gourd carving.

Or the gourd handicraft article colored by the rosin ink is placed in a damp and dark basement, observed after being placed for 1 to 2 days, and the gourd carving and dyeing part is wiped by using a paper towel, and the result shows that the paper towel is not dyed with any black stain or oil stain, which also indicates that the rosin ink has strong adhesion and is tightly adhered to the carving groove of the gourd handicraft article.

(3) The inventors of the present invention judged that the stability was high if the ink was uniform without precipitation, and whether the ink had precipitation or not was judged to be stable. After the rosin ink is prepared, the rosin ink is placed for 30 days, ink on the uppermost layer, the middle layer and the bottommost layer of the rosin ink is scooped up by a long handle spoon and placed in a taste dish, and the taste dish is stirred by a glass rod to observe whether black granular matters are settled on the taste dish or not. Some of the common commercial inks are prone to precipitation due to their formulation or processing.

(4) Washing with clean water

Experiment one: taking the gourd handicraft article manufactured by the method in the embodiment 1, fully airing, respectively standing for 10 days, 20 days and 30 days, then rinsing the dyed carved pattern with 100mL of clear water, receiving the rinsing water by a white porcelain plate, wiping the carved pattern with a paper towel after rinsing, and observing the color of the paper towel, wherein the result shows that the color of the paper towel is unchanged in 3 samples; and meanwhile, observing the color of the shower water in the white porcelain plate, and finding that the water is colorless and is not stained by any ink. This shows that the rosin ink is not decolorized by rinsing with clear water, and the rosin ink has strong coloring power and is not decolorized for a long time after being dyed on the gourd, and can not be decolorized even by rinsing with water.

Experiment two: the gourd handicraft article prepared by the method in example 1 was completely dried in the air, and was left to stand for 10 days, 20 days, and 30 days, respectively, and was placed in a white plastic tray, and was soaked in a large amount of tap water, and during soaking, the gourd was pressed with a weight, and the dyed carved pattern was always in a state of being soaked in water. After soaking for 12 hours, wiping the engraved pattern with a paper towel, and observing the color of the paper towel, wherein the result shows that the color of the paper towel is unchanged in 3 samples; this shows that the carved cucurbit dyed with the rosin ink of the present invention does not fade whether rinsed or soaked.

(5) Degree of convenience in use

The rosin ink of the present invention can be used after being prepared, and the ink rubbing and dyeing are performed in the manner of example 1.

The product 1 sold on the market is dye ink, or is mixed with peanut oil when in use, and is used after being prepared, so that the convenience is poor. The dosage proportion of the dye ink to the peanut oil needs to be controlled in the preparation process, and if the peanut oil is excessive, the phenomenon of oil leakage after dyeing is easily caused; if the peanut oil is insufficient, the ideal lubricating effect is not achieved, the glossiness after coloring is influenced, and the product has a rough feeling. If the finished product is prepared, the solubility between the dye ink and the peanut oil is not ideal, so that the oil is likely to float on the upper layer.

Therefore, the rosin ink of the present invention is far superior to the commercial products in terms of convenience.

(6) Smell(s)

The rosin ink is prepared from rosin serving as a raw material, and has a unique rosin taste. The common dye ink has the ink smell of chemical products. The rosin ink disclosed by the invention has the effects of soothing the nerves and helping sleep, and is pleasant to smell.

Example 6

In this example, example 1 was compared with each comparative example, and it was confirmed that the formulation of the present invention has a more significant advantage than the formulation of the comparative example, demonstrating that the formulation of the rosin ink of the present invention as a whole is not indispensable. When certain raw materials are reduced, the product cannot achieve an ideal effect, and the color fastness, the color durability and the like of later carving and coloring are influenced.

Compared to example 1, the difference is that comparative example 1: lard is not used;

comparative example 2: black sugar powder is not adopted;

comparative example 3: honey is not adopted;

comparative example 4: bait tea is not adopted;

comparative example 5: the consumption of the raw materials of pine branches, pine needles and pine barks is greatly reduced;

comparative examples 1 to 5 are comparisons of the rosin ink products by the present inventors, and specifically are as follows:

TABLE 3 comparison of rosin ink products of example 1 with comparative examples 1 to 5

From the description in the above table, the rosin ink product of the present invention, which is made of raw materials with a specific ratio, when one of the raw materials is reduced or absent, will cause the properties of the final product to change, thereby affecting the coloring effect of the gourd sculpture at a later stage.

The raw material of the rosin ink in the invention is derived from pure natural vegetable or animal oil, such as rosin oil with rosin; such as plant ash; even some edible raw materials such as honey, bait tea powder, lard and the like have no pollution; the printing ink of the printer especially contains antioxidant hydroquinone, adhesive polyvinylpyrrolidone, cosolvent N-methyl-2-pyrrolidone, diethylene glycol and the like, and the organic components have certain influence on the body of the engraver. The rosin ink of the present invention is clearly more safe.

From the analysis of the coloring power, durability, coloring effect and the like, it can be seen from table 1 that the effect of the rosin ink of the present invention is far superior to that of the printer ink.
