Problems solved by technology

In recent years, a kind of hydrolysis pen has appeared. The ink of the hydrolysis pen can make the handwriting disappear when it meets water. However, after writing on the wall, the handwriting can be dissolved and disappeared by water, but it will still leave yellow marks on the wall after drying. Wipe it clean. In addition, in the season of high humidity, after writing with the hydrolytic pen, the handwriting will disappear soon after being wet, which will seriously affect the use effect.

preparation example Construction

[0014] The preparation method of color paste microcapsule core layer, comprises the steps:

[0015] Step 1: Mix sodium dodecylbenzenesulfonate, acrylic acid, ammonia water and water, add methyl methacrylate resin and organic pigment ultrafine powder under high shear emulsification and dispersion at 10000-20000r / min, and disperse for 10-40min , to prepare a nucleation seed emulsion, wherein, according to the mass percentage, sodium dodecylbenzenesulfonate is 2.5-5.5%, acrylic acid is 0.5-1.5%, ammonia water is 1-2%, and methyl methacrylate resin is 2.5-2.5% 5.5%, organic pigment superfine powder is 3-7%, and water is supplemented to 100%. The particle size of the organic pigment ultrafine powder is preferably 10-15 nm. The shearing time for dispersing the organic pigment ultrafine powder is preferably: 10-40min. Preferably, the mass percentages of organic pigment ultrafine powder, sodium dodecylbenzenesulfonate, methyl methacrylate resin, acrylic acid and ammonia water are 5:...

specific Embodiment

[0017] Step 1: Under high-speed dispersion conditions, add 4g of sodium dodecylbenzenesulfonate, 1g of acrylic acid, and 1.5g of ammonia in 50g of water in sequence, mix and emulsify and disperse. Methyl ester resin and 5 g of organic pigment ultrafine powder were slowly added, and after the addition of the pigment, the emulsification and dispersion were continued for 15 minutes, and the nucleation seed emulsion was prepared. The organic pigment ultrafine powder is preferably 10-15 nm. Stirring and mixing can be carried out by means of a Fluke high shear emulsification disperser with a rotating speed between 10000-30000r / min. In step 1, the organic pigment ultrafine powder can be added as required, and the color depth of the ink can be adjusted according to the addition amount of the organic pigment ultrafine powder, which can be carried out within 3-7%.

[0018] Step 2: Take a 500ml four-necked flask, install a tetrafluoro stirring paddle in the middle hole, a condenser tube...

Abstract

The invention relates to the field of new materials, and a method for preparing microcapsule-type watercolor pen ink, comprising the following steps. Mix with water, emulsify and disperse to obtain nucleation seed emulsion; step 2: obtain color paste microcapsule core layer; step 3: obtain microcapsule color paste; step 4: according to mass percentage, make microcapsule color paste: 40- 60%, wetting agent: 0.4‑1%, defoamer: 0.4‑1%, glycerol: 2‑6%, ethanol: 10‑15%, bactericide: 0.1‑0.3%, the rest is deionized water , stir and mix until there is no oil shrinkage to obtain micro-encapsulated watercolor pen ink. The invention adopts the microcapsule polymerization technology, wraps the pigment inside the organic polymer, and uses the hydrophilic group to modify the outside.

Description

technical field [0001] The invention relates to the field of new materials, in particular to watercolor pen ink. Background technique [0002] It is a child's nature to like to paint and draw on the wall. Even if there are large pieces of paper and small blackboards at home, children will still doodle on the wall. At present, the pens for children to write and draw mainly include watercolor pens and whiteboard pens. Domestic watercolor pens and whiteboard pens cannot be wiped off after they are written on the latex paint wall. Some imported watercolor pens can be written on the surface of low PVC latex paint for a short period of time. After erasing, it will still leave yellow marks over time. In recent years, a hydrolysis pen has appeared. The ink of the hydrolysis pen can make the handwriting disappear when it encounters water. However, after writing on the wall, although the handwriting can be dissolved and disappeared by the water, it will still leave yellow marks on th...
