Problems solved by technology

[0004] To sum up, compared with rice paper and water writing paper, water writing cloth has its own unique advantages, but the water writing cloth currently on the market is expensive, and there are paint penetration during coating, handwriting diffusion during water writing, After drying, there are defects such as imprinting, which limits the promotion and use of water writing cloth
Looking at the patents and documents related to water-based cloth, there is no detailed description of the key part that determines the performance of water-based cloth—the coating formula and preparation method of the overcoat.

Embodiment 1

[0034] Taking 50mL of water as an example, the mass ratio of raw materials used to prepare the water-based environmental protection water-based cloth overcoat is:

[0035]

[0036]

[0037] Its preparation method consists of the following steps:

[0038] Step 1: Weigh the methyl cellulose according to the above mass ratio, and evenly sprinkle it into the water under the state of rapid mechanical stirring, and stir for 2 hours, so that the methyl cellulose is evenly dispersed in the water, and a uniform cellulose glue is obtained .

[0039] Step 2: After the cellulose glue is prepared, under continuous stirring, slowly add the ultrafine silica powder into the cellulose glue, and stir for 1.5 hours to obtain a uniform ultrafine silica powder system.

[0040] Step 3: Add defoamer GY330, dispersant 5040, polyether-modified polydimethylsiloxane, environment-friendly propylene glycol ether film-forming agent and preservative KSG102S to the superfine silica powder system accor...

Embodiment 2

[0049] Taking 50mL of water as an example, the mass ratio of raw materials used to prepare the water-based environmental protection water-based cloth overcoat is:

[0050]

[0051] Its preparation method consists of the following steps:

[0052] Step 1: Weigh the methyl cellulose according to the above mass ratio, and evenly sprinkle it into the water under the state of rapid mechanical stirring, and stir for 3 hours, so that the methyl cellulose is evenly dispersed in the water, and a uniform cellulose glue is obtained .

[0053] Step 2: After the cellulose glue is prepared, under continuous stirring, slowly add the superfine silicon micropowder into the cellulose glue, and stir for 2 hours to obtain a uniform superfine silicon micropowder system.

[0054]Step 3: Add defoamer GY330, dispersant 5040, polyether-modified polydimethylsiloxane, environment-friendly propylene glycol ether film-forming agent and preservative KSG102S to the superfine silica powder system accordin...

[0058] Taking 50mL of water as an example, the mass ratio of raw materials used to prepare the water-based environmental protection water-based cloth overcoat is:

[0059]

[0060]

[0061] Its preparation method consists of the following steps:

[0062] Step 1: Weigh the methyl cellulose according to the above mass ratio, and under the state of rapid mechanical stirring, evenly sprinkle it into the water, stir for 1 hour, so that the methyl cellulose is evenly dispersed in the water, and a uniform cellulose glue is obtained .

[0063] Step 2: After the cellulose glue is prepared, under continuous stirring, slowly add the ultrafine silica powder into the cellulose glue, and stir for 0.5 hours to obtain a uniform ultrafine silica powder system.

[0064] Step 3: Add defoamer GY330, dispersant 5040, polyether-modified polydimethylsiloxane, environment-friendly propylene glycol ether film-forming agent and preservative KSG102S to the superfine silica powder system according...

Abstract

The invention relates to a water-based environment-friendly water writing fabric covering coating. The water-based environment-friendly water writing fabric covering coating taking cellulosic derivatives as a tackifier and taking kaolin or the same class of inorganic salt such as talc powder or calcium carbonate as padding pigment is prepared by utilizing the crosslinking connection action of superfine quartz powder and the water changing transparency characteristic of the water-changing-color ink and adding corresponding auxiliaries. According to the invention, water is used as a dispersion medium, so that the water-based environment-friendly water writing fabric covering coating is good in property, non-toxic and environment-friendly, for the water writing fabric prepared by adopting the coating, the coating is not easy to penetrate during applying, the chirography is clear and indiffusible during writing, proper in water-retention time, free from prints after being dried, the water writing fabric can be used for repeatedly writing for many times, the coating is low and easily available in raw materials, and the prepared water writing fabric is high in performance cost ratio, thereby being beneficial to popularization and use.

Description

technical field [0001] The invention belongs to the technical field of water-based paints, and in particular relates to a water-based environment-friendly water-based cloth overcoat paint for water-based cloth. Background technique [0002] Soft pen calligraphy and painting practice is not only bigger to paper consumption, and the paper for calligraphy and painting is expensive, therefore, limits the practice of people's soft pen calligraphy and painting to a certain extent. A new type of paper called "water writing paper" is now on the market. Using this kind of paper, you can use a clean brush dipped in water for calligraphy and painting, and the color of the colored layer will appear on the paper, forming handwriting and patterns. After a few minutes, the handwriting disappears, and you can practice calligraphy and painting repeatedly. This product uses water instead of ink for calligraphy and painting practice, which is economical, hygienic, convenient and magical, heal...
