Description

Technical Field

[0001] This invention relates to the field of ink preparation technology for calligraphy and painting, specifically to a quick-dissolving, no-grind ink and its preparation method. Background Technology

[0002] Ink is a core consumable for traditional calligraphy and painting. Currently, the mainstream products are divided into two categories: one is traditional solid ink sticks, which need to be ground with water using an inkstone before use. The grinding process is time-consuming and laborious, and the fineness of the grinding depends on manual operation, making it difficult to guarantee uniformity; the other is liquid ink, which does not require grinding, but has problems such as easy leakage during transportation, easy freezing at low temperatures, short shelf life at room temperature, and large carrying volume.

[0003] In recent years, a small number of "no-grind toner" products have appeared on the market, but they generally have the following defects: 1) slow dissolution speed, easy to produce agglomerated particles during the dissolution process, affecting the smoothness of writing; 2) the formula contains industrial adhesives, which may corrode paper with long-term use and does not meet environmental protection requirements; 3) the toner has a dense structure and weak water absorption capacity, and cannot quickly form uniform ink.

[0004] In view of the shortcomings of the existing technologies, there is an urgent need to develop a calligraphy and painting ink product that combines "fast dissolution, environmental protection, portability, and excellent writing performance" to solve the pain points of using traditional ink sticks and liquid inks. Summary of the Invention

The toner and lampshade work synergistically to ensure smooth writing without pen stagnation, and the ink color is stable and resistant to fading after drying. Attached Figure Description

[0024] Figure 1 This is a flowchart illustrating the preparation process of the present invention. Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1 The present invention provides an instant ink that does not require grinding. The instant ink that does not require grinding comprises the following components by weight: 5-15 parts of bone glue, 2-8 parts of rock sugar, 20-40 parts of carbon powder, 15-30 parts of oil fume powder, 0.5-2 parts of borneol, 0.1-0.5 parts of artificial musk, and 0.3-1.5 parts of plant pigment.

[0027] The bone glue is food-grade bone glue; the carbon powder is nano-grade carbon black; and the soot powder is first-grade tung oil soot powder.

[0028] The plant pigment is either carbon black plant pigment or madder pigment, and the plant pigment needs to be dissolved in deionized water at a mass ratio of 1:5 before use.

[0029] A method for preparing a fast-dissolving, non-grinding ink includes the following steps:

[0030] Step 1: Raw material pretreatment:

[0031] Pretreatment of bone glue: Crush the bone glue into particles with a diameter of 5-10mm, add 8 times its weight of deionized water, and soak at room temperature for 4-6 hours until the bone glue has completely absorbed water and softened (to avoid clumping during subsequent cooking).

[0032] Screening of toner and fume powder: Pass the toner and fume powder through a 200-mesh sieve to remove impurity particles; then screen them through an air classifier to ensure that the toner particle size is ≤100nm and the fume powder particle size is ≤150nm, and set aside for later use;

[0033] Fragrance grinding: Mix borneol and artificial musk, grind them in an ultra-fine grinder to a particle size of 20-50μm, and set aside; dissolve the plant pigment in a small amount of deionized water (pigment: water = 1:5) to prepare a pigment solution for later use;

[0034] Step 2: Preparation of bone glue solution:

[0035] Pour the pretreated bone glue and soaking water into a stainless steel reactor and start stirring (150-200 r / min).

[0036] The temperature is raised by electric heating, with a heating rate of 5℃ / min. After the temperature reaches 100℃, it is kept at a constant temperature for 8 hours (stirring for 30 minutes every hour during this period to prevent the bottom from gelatinizing).

[0037] After the cooking process is complete, add all the rock sugar and continue stirring for 20-30 minutes until the rock sugar is completely dissolved, resulting in a transparent gelatin-rock sugar mixture. Cool to 60-70℃ for later use.

[0038] Step 3: Preliminary preparation of ink paste:

[0039] Add the screened carbon powder and oil fume powder to the bone glue-rock sugar mixture solution in sequence, stirring for 30 minutes after each addition (increasing the speed to 250-300 r / min) to ensure that the powder and solution are fully mixed.

[0040] Add the ground borneol-artificial musk mixture and stir for 20 minutes; then slowly add the plant pigment solution while stirring (200 r / min). After the addition is complete, continue stirring for 15 minutes to obtain the preliminary ink paste.

[0041] Step 4: Grind and refine the ink paste:

[0042] Transfer the initial ink paste to a colloid mill, adjust the grinding gap to 5-10 μm, and perform the first grinding (30 minutes).

[0043] After the first grinding, the ink paste is transferred to a ball mill (agate balls are used to avoid metal contamination). The ball milling speed is controlled at 400 r / min and the grinding time is 2-3 hours until the fineness of the ink paste reaches 750-1000 μm (detected by a laser particle size analyzer).

[0044] After grinding, let the ink paste stand for 1 hour to remove internal air bubbles and obtain a fine and uniform refined ink paste.

[0045] Step 5: Ink Preparation:

[0046] Add deionized water to refined ink paste. The mass ratio of ink paste to deionized water is 1:5-1:10 (adjust according to the required ink concentration; 1:8 is preferred for writing and 1:6 is preferred for drawing).

[0047] Turn on high-speed stirring (500-600 rpm) for 15-20 minutes to ensure the ink paste is completely dissolved and forms a uniform ink without particles;

[0048] Filter the ink (through a 300-mesh nylon filter) to remove any undissolved tiny particles, and set aside.

[0049] Step Six: Spray Drying

[0050] Start the spray drying tower, preheat the tower body, control the inlet air temperature to 95-105℃, the outlet air temperature to 60-70℃, the atomization pressure to 0.2-0.4MPa, and the inlet air velocity to 1.2-1.8m / s;

[0051] The filtered ink is fed into the atomizer of the spray drying tower (a centrifugal atomizer with an atomization particle size of 50-100μm) via a peristaltic pump at a feed rate of 50-80mL / min.

[0052] After being atomized, the ink comes into contact with hot air and dries instantly to form toner particles. The toner particles are collected by a cyclone separator to obtain a porous, fluffy, quick-dissolving, no-grind toner.

[0053] The collected toner is cooled to room temperature (25-30℃) and then vacuum-packed (the packaging is filled with nitrogen to extend the shelf life) to obtain the finished product.
