Description

Technical Field

[0001] The invention relates to the technical field of animal marking paint preparation, and more particularly to an animal marking paint and a preparation method thereof. Background Art

[0002] Wool marking paint is a special material for printing numbers on individual sheep during the breeding, reproduction, epidemic prevention, quarantine and grouping of sheep. It is used to distinguish flocks or identify individuals. In the initial sheep farming production, due to the lack of special wool marking paint, farmers and herdsmen mainly marked sheep with paint, asphalt, numbers cut out of wool, and numbers sewn and printed on wool. After paint and asphalt are contaminated with wool, they are easy to react chemically with the protein in the wool, which is difficult to remove in a short period of time, seriously affecting the quality and value of wool. At the same time, in wool spinning processing, it also increases the cost of wool washing and processing for wool spinning enterprises. After asphalt and paint are heated and melted, they will also contaminate other wool fibers, affecting the washing effect and production efficiency, and even affecting the quality of wool spinning products. Asphalt wool and paint wool not only affect the income of farmers and herdsmen and breeders. It also brings unimaginable harm to the production and product quality of wool spinning enterprises, and causes great economic losses. In the case of the sluggish wool market in recent years, asphalt wool and paint wool have no economic value, and most farmers and herdsmen can only abandon them. Methods such as cutting numbers out of wool or sewing printed numbers on sheep's wool are time-consuming, labor-intensive, slow, and ineffective. In addition, the sewn numbers are easily eaten by sheep, which is not suitable for large-scale farming needs.

[0003] The most rapidly developing meat sheep industry still needs to use wool marking paint to accurately complete the sheep flocking, quarantine, epidemic prevention, breeding and reproduction. Existing similar products are bottled and self-spraying. Bottled simple paint has the problems of single color, slow drying speed and easy precipitation; self-spraying has the problem of single color and high cost.

[0004] Therefore, it is necessary to provide an improved wool marking paint to meet the requirements of low cost, easy to carry, high biosafety, long-lasting durability and easy cleaning in sheep breeding and production. Summary of the invention

[0005] In view of this, the present invention is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] On the one hand, an embodiment of the present invention provides an animal marking paint, which includes the following raw materials in weight fractions: 15-25% oil-in-water emulsifier, 20-25% organic solvent; 0.8-1% emulsifier, 0.6-1.0% adhesive, 0.1-0.2% preservative, 0.4-0.6% pigment, 32.2-53.1% water, and 10-15% drying agent.

[0008] In a preferred embodiment, the water-in-oil emulsifier is lanolin.

[0009] In a preferred embodiment, the organic solvent is isopropyl acetate.

[0010] In a preferred embodiment, the emulsifiers are rosin and stearic acid, with weight fractions of 0.4-0.5% and 0.4-0.5% respectively.

[0011] In a preferred embodiment, the binder is soft kaolin.

[0012] In a preferred embodiment, the preservative is ε-polylysine.

[0013] In a preferred embodiment, the pigment is a red oil-soluble pigment, a blue oil-soluble pigment or an oil-soluble pigment of another color.

[0014] In a preferred embodiment, the drying agent is ethanol.

[0015] The second aspect of the embodiment of the present invention provides a method for preparing the animal marking paint, the process comprising:

[0016] 1) mixing lanolin and isopropyl acetate and heating and melting them to obtain a mixture 1;

[0017] 2) mixing stearic acid and rosin, heating and melting, to obtain a mixture 2;

[0018] 3) heating and melting soft kaolin and ε-polylysine to obtain a mixture 3;

[0019] 4) stirring and dissolving the pigment and water to obtain a mixture 4;

[0020] 5) Mixture 1, mixture 2, mixture 3 and mixture 4 are stirred and mixed evenly, and a certain amount of ethanol is added and packaged.

[0021] It can be seen from the above technical solution that, compared with the prior art, the coating of the present invention has the following beneficial effects:

[0022] 1. It is not easy to fade under weather changes in the natural environment and is durable. At the same time, in the later wool processing process, the pigment can be easily washed away using a specific detergent.

[0023] 2. When applied on sheep wool blankets, it will not chemically react with the wool and will not produce chemical reactions or toxic effects when in contact with the skin.

[0024] 3. The paint has good viscosity and uniformity, is easy to fill and transport, is not prone to stratification and sedimentation, and is suitable for bottles of different sizes.

[0025] 4. After being used on the surface of sheep, it can not only permanently mark the color on the wool, but also is easy to rinse and decolorize during wool textile processing, which greatly reduces the economic losses of wool raw materials and product processing, contributes to the healthy development of the sheep industry, and increases the income of farmers and herdsmen.

[0026] In summary, the raw materials of this patent are all commercially available products, which are safe, reliable and easy to purchase. Using ethanol as a desiccant is low-cost and easy to purchase. It can not only play the role of ethanol as a drying agent, but also will not affect the chemical properties of other reagents. Using ε-polylysine as a preservative is safer than other chemical preservatives and has high biological safety. After marking the surface of the sheep, the coating of the present invention retains its color for a longer time and the color fades slowly. Experiments have shown that the product retention time can reach about eight months in an outdoor natural environment, which fully guarantees the durability of the biological coating. DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The raw materials and effects used in the embodiment are as follows:

[0029] Lanolin: Water-in-oil emulsifier, soluble in hot ethanol, very slightly soluble in ethanol. Has excellent emulsifying properties. Lanolin refers to a kind of secreted oil attached to wool, generally in the form of a soft brown or light yellow paste. Lanolin is extracted from natural wool or concentrated, extracted and refined from wool washing waste liquid, and its main component is sterol ester.

[0030] Isopropyl acetate: organic solvent, slightly soluble in water, soluble in ethanol. Mainly used as solvent for coatings, printing inks, etc., and also commonly used as dehydrating agent in industry, extractant and flavoring component in drug production. This product has a fruity aroma, and has an apple aroma after dilution. Natural products exist in pineapples, pears, cocoa, etc., and are allowed to be used as edible spices according to GB2760-86 of my country. Mainly used as a solvent for preparing rum flavor and fruit-type flavors. Mainly used as a solvent and extractant for cellulose derivatives, plastics, oils and fats, and widely used in chemical, pharmaceutical, biological pesticide, coating, ink and other industries.

[0031] Stearic acid: Emulsifier, a compound produced by the hydrolysis of oils and fats, which has a lubricating effect. It is an unsaturated fatty acid with antioxidant effects, which can promote the body's metabolism and, to a certain extent, achieve the effect of beauty and skin care. Stearic acid is widely used in oral medications. It is non-toxic and non-irritating. Stearic acid is a saturated fatty acid that promotes the mixing of oil and water due to its non-polar properties. Stearic acid is often used as an emulsifier in cosmetics to stabilize the oil-water mixture and prevent separation.

[0032] Rosin: Emulsifier is a natural resin extracted from pine plants, mainly derived from the oleoresin secreted by pine trunks. Rosin emulsifier is an important chemical product, usually made by emulsifying rosin. Rosin emulsifier has good emulsification and stability and is widely used in the preparation of various types of coatings, paints and adhesives. Since rosin is a non-polar substance, it will be stratified in water and difficult to mix and use evenly. The presence of rosin emulsifier can effectively solve this problem, allowing rosin to be better mixed with water to form a stable mixed liquid. Due to the high efficiency, stability and ease of use of rosin emulsifier, it has become a mainstream adhesive formula. Rosin itself has good adhesion and viscosity, so adding rosin can keep the emulsified oil mixture stable and improve its consistency and adhesion.

[0033] Soft kaolin: adhesive, a non-metallic mineral, is a clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and fine, it is also called dolomite. It is named after Gaoling Village in Jingdezhen, Jiangxi Province. Its pure kaolin is white, fine, soft and soil-like, with good physical and chemical properties such as plasticity and refractoriness. Its mineral composition is mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals. Kaolin has a wide range of uses, mainly used in papermaking, ceramics and refractory materials, secondly in coatings, rubber fillers, enamel glazes and white cement raw materials, and a small amount is used in plastics, paints, pigments, grinding wheels, pencils, daily cosmetics, soaps, pesticides, medicines, textiles, petroleum, chemicals, building materials, national defense and other industrial sectors. In textile printing and dyeing, kaolin is usually used as an adhesive. Kaolin can not only act as an adhesive, but also increase the softness, glossiness and feel of the fabric. Kaolin also has some special properties, such as good dispersibility, stability and flame retardancy.

[0034] ε-polylysine: preservative, compared with other preservatives, has the advantages of broad antibacterial spectrum and good stability. ε-polylysine is a polypeptide with antibacterial effect, which can be decomposed into lysine in the human body, and lysine is one of the eight essential amino acids for the human body. Therefore, ε-polylysine is a nutritional antibacterial agent, which is safer than other chemical preservatives.

[0035] Pigments: red oil-soluble pigments, blue oil-soluble pigments, or oil-soluble pigments of other colors.

[0036] The red color is carmine, also known as edible red No. 102 (Japan), edible red No. 7, Ponceau 4R, scarlet, and bright scarlet. It is an aqueous azo colorant. Its chemical name is 1-(4'-sulfonic acid-1'-naphthazo)-2-naphthol-6,8-disulfonic acid trisodium salt. It is an isomer of amaranth red and has a molecular formula of C 20 H 11 O 10 N 2 S 3 Na 3 As a food pigment, carmine can be used to color fruit juice drinks, blended alcoholic beverages, carbonated beverages, candies, cakes, ice cream, yogurt and other foods.

[0037] The blue color is made of oily blue ink pigment BP-P30-EA, which uses multiple nano-modification technologies such as inorganic-organic composite doping, coating, and modification. It can be used in coatings, inks, printing and dyeing, or in fields with special optical requirements for color paste. It is safe and environmentally friendly, and does not release toxic and harmful substances.

[0038] Ethanol: desiccant, is a hydrophilic solvent, under certain conditions, can play the role of desiccant, that is, adsorb moisture in the surrounding environment. In the present invention, the water content is relatively high, which dilutes the ethanol to a certain extent. The ethanol is designed to be excessive in the system, and its boiling point is 78°C. When heated to 80°C in the reagent mixture, as the ethanol evaporates, it can play the role of ethanol as a drying agent, and will not affect the properties of other reagents.

[0039] Example 1

[0040] The above components are mixed according to different proportions. The formula list of a typical embodiment of the animal marking paint of the present invention is shown in Table 1:

[0041] Table 1 Animal marking paint ratio table

[0042]

[0043]

[0044] The animal marking paint is prepared as follows:

[0045] Mix lanolin and isopropyl acetate in the above-mentioned proportions, heat and melt, and stir while heating until they are completely melted and uniform; mix stearic acid and rosin in the above-mentioned proportions, heat and melt, and stir while heating until they are completely melted and uniform; heat soft kaolin and ε-polylysine in the above-mentioned proportions, melt, and stir while heating until they are completely melted and uniform; stir and dissolve pigment and water in the above-mentioned proportions; stir and mix all the above-mentioned molten components evenly, heat and stir for 1 hour, and add ethanol after the mixed solution cools to room temperature to obtain animal paint, which is divided for use.

[0046] Example 2 Persistence Detection

[0047] The durability of the three different animal marking paints obtained in Example 1 was tested by the following method:

[0048] In March 2024, the effect of this product was tested at the sheep breeding farm of Xinjiang Academy of Agricultural Reclamation Sciences. The sheep breeding farm is located in Shihezi, Xinjiang, between 44°15′43″~44°19′13″N, 85°59′12″~86°08′13″E, in the middle section of the northern foothills of the Tianshan Mountains and the southern edge of the Gurbantunggut Desert. It is 450.8 meters above sea level and has a temperate continental climate with little precipitation and dryness, long and severe cold winters, and short and hot summers. The frost-free period is 168 to 171 days, with an average temperature of 25.1 to 26.1°C, a maximum temperature of 42.1°C, a minimum temperature of -41.8°C, an average annual precipitation of 213 mm, and an annual evaporation of 1537 mm. In the experiment, 150 sheep were randomly selected and divided into three groups with 50 sheep in each group. The sheep were painted with the paint provided by the present invention and numbered. The marking part was on the back of the sheep, and the painting area was about 5×5 cm. 2 ; Observation records were made every month to observe the clarity and color changes of the paint on the body surface. The experiment ended in November when winter arrived. The specific results of the observation are shown in Table 2.

[0049] Under the condition of natural weather changes, farmers and herdsmen hope that the coating can maintain the sheep numbers for more than 6 months. According to the above results, the coating provided by the present invention can still be identified under ultraviolet irradiation, rain erosion and wind erosion for up to 6 to 8 months, although the color is dark due to dirt such as mud and sand covering the wool surface, and the coating can still be identified under the conditions of ultraviolet irradiation, rain erosion and wind erosion, and has the characteristics of good stability and durability.

[0050] Table 2 Durability test

[0051] Sample No. 1# 2# 3# 3 months Clear markings Clear markings Clear markings 6 months The color is dark and clearly visible The color is dark and clearly visible The color is dark and clearly visible 8 months Color diffusion and unclear markings The color is dark and clearly visible The color is dark and clearly visible

[0052] At the same time, compared with the invention patent CN 106947388 A, the three ratios of the present invention are clearly identifiable and the colors do not fade at 6 months, and the 2# and 3# ratios are still clearly identifiable in the 8-month outdoor marking test. And the color of the control patent becomes lighter in the outdoor test of more than 4-6 months. Therefore, after periodic experimental comparison of sheep living naturally outdoors, it is found that the durability of the present invention is superior.

[0053] Example 3 Washability Test

[0054] See Table 3;

[0055] Table 3

[0056] Shimizu Wool and cashmere detergent (commercially available) The coating of the present invention Cannot be cleaned Can be cleaned asphalt Cannot be cleaned Cannot be cleaned paint Cannot be cleaned Cannot be cleaned

[0057] After the sheep are sheared, the paint and asphalt marked on the wool are difficult to wash off, which seriously affects the quality and processing performance of the wool and greatly reduces the economic benefits of the wool. After the sheep are marked, the sheep marking of the present invention is not easy to wash off after daily rain washing, but the wool can be cleaned by a commercially available special wool and cashmere detergent, thereby reducing the economic losses caused by the paint in the wool production, eliminating the need for manual sorting of the marked wool, reducing labor and improving economic benefits.

[0058] Example 4 Economic Benefit Calculation

[0059] The wool-specific coating provided by the present invention is used to mark fine-wool sheep and other meat sheep. According to the average wool production of 7.5 kg per sheep, the cost is 28 yuan per kg, and the loss of each sheep is reduced by 1%, which can reduce 2.1 yuan. The loss of 100 sheep can be reduced by 210 yuan. According to the average wool production of 3 kg per sheep, the cost is 10 yuan per kg, and the loss of each sheep is reduced by 1%, which can reduce 0.3 yuan. The loss of 100 sheep can be reduced by 30 yuan. In addition, the coating does not damage the sheep, is safe for humans and animals, has good durability, can reduce the labor cost of multiple markings, and has significant economic benefits.

[0060] In summary, the animal marking paint and the preparation method thereof provided by the present invention have high application value in animal husbandry. The paint of the present invention is not easy to fade during the weather changes in actual production, has good stability, and can meet the production needs of the paint to be kept for more than 6 months. After marking the surface of the sheep, the paint is easy to clean with a special wool and cashmere detergent, avoiding the damage of traditional asphalt wool and paint wool to wool and wool spinning, and also reducing manpower consumption, greatly improving production efficiency and production benefits. The animal marking paint and the preparation method thereof of the present invention can be widely used in the breeding of sheep and goats of different breeds and different hair colors, as well as in the feeding and management of other animals and livestock, and has the advantage of wide applicability.
