Description

Technical Field

[0001] The invention relates to the technical field of peach gum ink, in particular to a preparation process of peach gum ink. Background Art

[0002] Peach gum is a gelatinous, translucent substance secreted by the trunks of Rosaceae plants such as peach or mountain peach after mechanical injury or disease. The solid substance formed by air drying on the trunk or other dehydration methods is raw peach gum. Raw peach gum is a pink or light yellow translucent solid block with a smooth surface. It can generally only swell and is not easy to completely dissolve. The aqueous solution is viscous and belongs to the polysaccharide substance.

[0003] Traditional ink is prepared by mixing animal gelatin. Animal gelatin is a protein that is easily degraded and loses its viscosity. The ink particles fall off and lose their luster, which is not conducive to ensuring the display of the ink effect.

[0004] The stickiness of peach gum can fully ensure the connectivity of ink particles, which helps to fully ensure the glossiness of ink. However, how to fully utilize the characteristics of peach gum in ink is a difficult problem in this field. Summary of the invention

[0005] The invention aims to solve the shortcomings in the prior art and provides a preparation process of peach gum ink.

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

[0007] A preparation process of peach gum ink comprises the following steps:

[0008] S1. Peach gum crushing and screening: The surface of the peach gum is cleaned by a cleaning device, and after cleaning, the peach gum is crushed by a cutting device, and the crushed peach gum is collected centrally;

[0009] S2, peach gum processing: the crushed peach gum is introduced into a blender and then purified water is added to obtain a soaking liquid, and the soaking liquid temperature is controlled between 60-70°, and the pH value of the soaking liquid is adjusted and the solution temperature is increased to between 75-80°, and the temperature is maintained until the peach gum is completely dissolved, and the dissolved soaking liquid is processed so that the solution is filtered after standing and settling to obtain peach gum liquid;

[0010] S3, ink material preparation: obtain carbon black, aromatic agent, moisturizer, dispersant, defoamer, preservative and purified water;

[0011] S4, ink material processing: crush the carbon black through a wall-breaking crusher;

[0013] S6. Prepare ink: grind the ink paste and 1 / 3 of pure water in a grinder, filter through a sieve after grinding, if there is any problem that it does not pass through the sieve, grind it all again until it completely passes through the sieve; after it completely passes through the sieve, transfer the mixed liquid to a blender, pour the remaining 1 / 3 of pure water into the blender and stir and mix for 5-8 minutes, set a filter collector at the discharge end of the blender to filter and collect.

[0014] Compared with the prior art, the present application crushes, soaks, decolorizes and bleaches peach gum, thereby improving the transparency of peach gum liquid while ensuring its viscosity, which can effectively avoid the situation where traditional peach gum affects the ink color, thereby effectively replacing animal gelatin, and through emulsification and grinding operations, the carbon black particles and peach gum liquid are fully mixed to ensure that the carbon black particles are adhered, and the adhesion effect between particles and between particles and paper is guaranteed.

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0044] Reference Figure 1 A preparation process of peach gum ink comprises the following steps:

[0045] S1. Peach gum crushing and screening: The surface of peach gum is cleaned by cleaning equipment, and crushed by cutting equipment after cleaning. At the same time, the crushed peach gum is collected centrally to fully ensure the quality of raw materials for preparing peach gum liquid, starting from the source. At the same time, by ensuring the consistency of the particles after the peach gum is crushed, it helps to ensure that the reaction time of the particles is in the same time period, which can make the reaction more uniform and ensure the quality of the peach gum liquid.

[0046] S2. Peach gum processing: introduce the crushed peach gum into the blender and then add pure water to obtain the soaking liquid. The mass ratio of peach gum to pure water is 1:1.8-2, which can effectively and comprehensively soak the peach gum, and control the temperature of the soaking liquid between 60-70°, adjust the pH value of the soaking liquid and increase the solution temperature to between 75-80°, maintain the temperature until the peach gum is completely dissolved, and process the dissolved soaking liquid so that the solution can be filtered after standing and settling to obtain peach gum liquid.

[0047] S3, ink making material preparation: obtain carbon black, fragrance, moisturizing agent, dispersant, defoaming agent, preservative and pure water; the mass ratio of peach gum liquid, carbon black, fragrance, moisturizing agent, dispersant, defoaming agent, preservative and pure water is 1:0.8-1:0.05-0.1:0.05-0.1:0.02-0.05:0.01-0.02:0.01-0.02:5-10; through the precise ratio between the materials, it is used to ensure the glossiness and quality of the finished ink. After the preparation is completed , ensuring that the finished ink has a certain fragrance, can have long-term fluidity and is easy to store for a long time, and can effectively prevent the colloid and ink particles inside it from agglomerating, so that it can be better used; the fragrance agent is selected from at least one of camphor oil, borneol powder, and camphor powder; the moisturizer is selected from at least one of Turkish red oil, cottonseed oil, rapeseed oil and glycerin; the preservative is selected from at least one of borneol, camphor, chitosan, and plant extract preservatives; the dispersant is an acrylic polymer dispersant, and appropriate agents are selected as needed to improve the quality of the final ink.

[0048] S4. Ink-making material processing: The carbon black is crushed by a wall-breaking crusher; the crushing effect of the carbon black is improved so that the carbon black can be crushed into finer particles, which can better mix the carbon black particles with the peach gum liquid and the corresponding agents more evenly, and can ensure the quality of the ink, so that the quality of the ink is consistent everywhere when writing.

[0049] S5, ink mixing: start the emulsifier, pour 1 / 3 of water into the emulsifier and heat it to 75-85°, then pour the peach gum liquid prepared in S2 into the emulsifier, and then pour the crushed carbon black into it, and finally pour the fragrance, moisturizer, dispersant, defoamer and preservative in turn. The emulsifier generates strong shear force, impact force and cavitation effect through the high-speed rotation of built-in stirring paddles, homogenizers and other components, which fully disperse and mix the raw materials such as oil phase, water phase and active ingredients in a short time, and form a uniform and delicate emulsion, and continue stirring until an ink paste is formed.

[0050] S6. Prepare ink: grind the ink paste and 1 / 3 of pure water in a grinder, filter through a sieve after grinding, if there is any problem that it does not pass through the sieve, grind it all again until it completely passes through the sieve; after it completely passes through the sieve, transfer the mixed liquid to a blender, pour the remaining 1 / 3 of pure water into the blender and stir and mix for 5-8 minutes, set a filter collector at the discharge end of the blender to filter and collect.

[0051] In the present invention, the cleaning equipment in S1 includes a high-pressure bubble cleaning device and a drying machine; the cutting equipment includes a cutter, a vibrating screen and an elevator;

[0052] The surface cleaning operation of peach gum includes the following steps:

[0053] The first step is to put the peach gum into the high-pressure bubble cleaning equipment, which is distributed in multiple stages to achieve a cycle of soaking and cleaning - fishing out and draining. It adopts existing technical equipment, and can achieve an effective combination of cleaning and drying through the ingenious cooperation between the equipment. In addition, through the multi-stage distribution mode, it can perform a cycle of cleaning, draining, re-cleaning, and re-draining, which can improve the cleaning quality of the peach gum and ensure that there is no attachment on its surface;

[0054] In the second step, the drying machine is set at the end of the high-pressure bubble cleaning equipment. After the peach gum is taken out and drained for the last time, it is transported to the conveyor belt of the drying machine. At the same time, the fan directly above the conveyor belt is operated to make the air flow downward to achieve drying. It can effectively dry the peach gum. Unlike the traditional drying method that causes the water to evaporate, the drying method can effectively blow away the water attached to the surface, but it does not affect its essence, that is, the internal water content will not be affected;

[0055] The crushing operation includes the following steps: the dried peach gum is conveyed into the feed hopper of the cutter so as to be conveyed into the cutter for cutting operation; the peach gum cut into pieces is conveyed to the vibrating screen for screening; the qualified peach gum falls down; the unqualified peach gum is conveyed to the feed hopper of the cutter again through the elevator for cutting again; the desired cutting parts can be selected according to the needs, and the screening can be fully carried out to ensure the consistency between the final cut particles; through the consistency between the above-mentioned cut particles, the reaction conditions and reaction time of the peach gum particles can be more uniform when they react later.

[0056] In the present invention, adjusting the pH value of the soaking liquid in S2 comprises the following steps:

[0057] The first step is to add any one of N-methyl-2-pyrrolidone and ethylene glycol amine to the soaking solution to make the pH value between 9 and 10;

[0058] The second step is to add hydrogen peroxide solution to adjust the pH value to between 6-7.

[0059] After adjusting the pH value, the dissolved soaking liquid is processed in the following steps: adding calcium hydroxide to completely dissolve it, adjusting the pH value to between 9 and 10 again, adding hydrogen peroxide solution and stirring, which can effectively bleach the peach gum liquid, remove the color in the peach gum liquid, and improve its transparency, so as to effectively display the carbon black particles and improve the color brightness of the ink.

[0060] In the present invention, the mesh number of the screen in S6 is 80-90 meshes, and the mesh number of the filter is 100-120 meshes, which fully ensures the fluidity of the final ink for writing use.

[0061] In the present invention, the grinder in S6 adopts a ball mill, the rotation speed of the ball mill is 4000-5000 rpm, and the grinding time of the ball mill is 1-2 hours, which fully ensures the quality of the ball mill so that the carbon black particles, peach gum particles, and various additives can be evenly mixed, convenient for mutual connection and function.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
